FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with benign prostatic hyperplasia is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about benign prostatic hyperplasia, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to benign prostatic hyperplasia, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on benign prostatic hyperplasia. Abundant guidance is given on how to obtain free-ofcharge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to benign prostatic hyperplasia, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on benign prostatic hyperplasia. The Editors

PROSTATIC

Overview In this chapter, we will show you how to locate peer-reviewed references and studies on benign prostatic hyperplasia.

The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and benign prostatic hyperplasia, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “benign prostatic hyperplasia” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

Non-medical Treatments for Benign Prostatic Hyperplasia: Balloons, Stents, Lasers and Cryosurgery Source: Current Opinion in Urology. 2(1): 8-11. February 1992. Summary: A majority of male patients with bladder outflow obstruction are treated satisfactorily by transurethral resection of the prostate (TURP). However, worries about mortality, morbidity and cost, combined with the progress of surgery towards minimally invasive therapies, have produced an array of potential alternatives. This article assesses those alternatives, including balloon dilatation, prostatic stenting, laser prostatotomy, and cryosurgical prostatectomy. The authors conclude that stents may

prove to be a suitable alternative to TURP in patients who are not candidates for TURP. They note that long-term follow-up data is not presently available. 17 annotated references. (AA-M). •

Finasteride in the Treatment of Clinical Benign Prostatic Hyperplasia: A Systematic Review of Randomised Trials Source: BMC Nephrology. 2(14): [17 p.]. December 2002. Summary: Benign prostatic hyperplasia (BPH) affects older men. This systematic review study determined the effectiveness and adverse effects of finasteride, used to treat BPH. Of the studies found in the review, 3 trials had active controls and 19 had placebo. In placebo-controlled trials, 8,820 patients received finasteride 5 milligrams and 5,909 placebo over 3 to 48 months. Over 48 months, finasteride produced greater improvements in total symptom score, maximum urinary flow rate, and prostate volume. Significantly more sexual dysfunction, impotence, ejaculation disorder, and decreased libido occurred with finasteride at 12 months. Significantly fewer men treated with finasteride experienced acute retention or had surgery at 24 or 48 months than with placebo. The authors conclude that information from many patients in studies of high quality showed beneficial effects of finasteride in terms of symptoms, flow rate, and prostate volume. 6 figures. 4 tables. 57 references.

Benign Prostatic Hypertrophy: 'Cost-Benefits' of Surgery Greater Than That of Drug Therapy Source: Drugs and Therapy Perspectives. 10(11): 13-15. November 24, 1997.

Summary: Benign prostatic hypertrophy (BPH), defined as enlargement of the prostate with associated urinary symptoms, affects a large percentage of men over the age of 50 years. Treatment options include a wait and see approach with the introduction of surgery when symptoms become severe, or long term drug therapy, which is mainly indicated for men with moderate symptoms with the aim of circumventing the need for surgery. This article considers the cost benefits of surgery versus drug therapy for BPH. It is possible, and perhaps even likely, that efficient drug therapy itself will reduce the need for prostate surgery by lowering the general level of symptoms. Cost benefit considerations become unfavorable when they are applied to younger men with mild or no symptoms, and most men in this age group will probably object to taking drugs for years to prevent a benign condition such as BPH. Furthermore, cost benefit considerations are of questionable relevance in patients with severe symptoms, who are likely to require surgical management. Men with moderate symptoms of BPH are generally considered the best candidates for drug treatment. However, the distinction between mild and moderate symptoms is arbitrary, and there are wide differences in patient tolerance of symptoms. One possible benefit of closer long term followup of BPH as a result of drug treatment might be an increase in the early detection of prostate cancer. The author concludes that, until more potent drugs are introduced, transurethral resection and other alternative surgical treatments will continue to be the principal treatment modalities for symptomatic BPH. 9 references.

Summary: Hyperthermia treatment of benign prostatic hyperplasia (BPH) is now being used after its earlier encouraging application in prostatic cancer. The author of this article reports on his experiences using a transrectal probe to deliver hyperthermia treatments. Objective and subjective improvement in obstructive and irritative symptoms has been reported in 40 to 60 percent of the cases. Other recently introduced machines use either the transrectal or the transurethral approach and induce higher temperatures than the original equipment. The author concludes that more time is needed to establish the optimum temperature in hyperthermia for BPH, the best and safest route to achieve this objective, how long each treatment should last, which patients should receive it, and how they should be selected and followed. 1 figure. 49 annotated references.

Summary: In this article, the authors report on a study in which they assessed the long term effects of finasteride on bladder outlet obstruction and symptoms in the treatment

of patients with benign prostatic hyperplasia. Of the original 36 patients assigned to treatment with 5 mg finasteride daily (group 1) or placebo (group 2) for 6 months, 27 completed an open extension study of 5 mg finasteride for 4 more years. The possible relief of bladder outlet obstruction was monitored with repeated pressure-flow studies at baseline, 6 months, and 4.5 years. Results showed that the treatment resulted in a further slight decrease in detrusor pressure at maximum flow rate in group 1 and a significant decrease in group 2 during the 4-year period, whereas improvement in maximum flow rate did not achieve statistical significance. Concomitantly, there was a significant improvement in obstructive and irritative symptoms. The authors conclude that finasteride decreases bladder outlet obstruction moderately and only occasionally relieves it completely. However, the decrease in obstruction achieved in many patients is sufficient to improve the symptoms significantly. The beneficial effect is long lasting. 2 figures. 2 tables. 24 references.

Summary: It is estimated that by the age of 60, half of all men will develop evidence of enlarged prostate (BPH, benign prostatic hyperplasia). Despite the large number of men affected by BPH, many men lack an awareness or knowledge about the condition and existing treatments. This article reviews BPH, how it happens, symptoms, and treatment options. BPH is a noncancerous enlargement of the prostate, a walnut-sized gland located just below the bladder (which stores urine); the prostate surrounds the urethra, the canal through which urine and semen pass out of the body. BPH symptoms occur when growth of muscular tissue and glands in the prostate combine and constrict the urethra. This can cause difficulty urinating, but generally does not interfere with sexual function. The author lists the typical symptoms of BPH. Diagnosis of BPH consists of a visit to a physician or urologist, a physical examination (including a digital rectal examination, or DRE), and patient history. If BPH is diagnosed, it only requires treatment if the symptoms are severe enough to be bothersome and if the function of the urinary tract is seriously affected. Treatment options include watchful waiting or a variety of surgical methods, including transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), laser surgery, open prostatectomy, transurethral microwave therapy (TUMT), and transurethral needle ablation (TUNA). Medications may also be used to treat BPH. The authors emphasize that effective

What We Do and Don't Know About Benign Prostatic Hyperplasia (editorial) Source: Current Opinion in Urology. 10(1): 1-2. January 2000. Contact: Available from Lippincott Williams and Wilkins. 241 Borough High Street, London, SE1 1GB, UK. +44 (0) 171940-7500. E-mail: [email protected]. Summary: Many urinary voiding complaints in elderly men are caused by benign prostatic hyperplasia (BPH); however, more recent research in this field indicates that some of these symptoms can be caused by bladder dysfunction. In an effort to clarify the differences, the author of this article reviews the current knowledge about BPH and its diagnosis and treatment. The author reminds readers to consider that age-related changes in bladder and central nervous system function, which may lead to lower urinary tract symptoms, may result in similar symptoms to those observed in patients with BPH. The lack of clear correlation between prostate size, urodynamic obstruction, and lower urinary tract symptoms has caused the questioning of the assumption that prostate growth is the key event. The author summarizes the current concepts regarding BPH treatment: watchful waiting is effective and appreciated by both patients and physicians; in case of a significant outlet obstruction, TURP is the most effective treatment, and risk has decreased considerably; and alternative minimally invasive therapies are especially attractive in high risk patients and those who prefer such a treatment over surgery. In addition, the author underscores the importance of adequate identification (diagnosis) before recommending the most appropriate therapy.

Efficacy of Terazosin, Finasteride, or Both in Benign Prostatic Hyperplasia Source: New England Journal of Medicine. 335(8): 533-539. August 22, 1996. Summary: Men with benign prostatic hyperplasia (BPH) can be treated with alpha1adrenergic antagonist drugs that relax prostatic smooth muscle or with drugs that inhibit 5alpha-reductase and therefore reduce tissue androgen concentrations. This article reports on a study in which the authors compared the safety and efficacy of placebo, finasteride (5 mg daily), terazosin (10 mg daily), and the combination of both drugs in 1,229 men with BPH. American Urological Association symptom scores and peak urinary flow rates were determined at baseline and periodically for 1 year. The mean changes from baseline in the symptoms scores in the placebo, finasteride, terazosin, and combination-therapy groups were decreases of 2.6, 3.2, 6.1, and 6.2 points, respectively. The mean changes at 1 year in the peak urinary flow rates were increases of 1.4, 1.6, 2.7, and 3.2 ml per second, respectively. Finasteride had no more effect on either measure than placebo. In the placebo group, 1.6 percent of the men discontinued the study because of adverse effects, as did 4.8 to 7.8 percent of the men in the other three groups. The authors conclude that, in men with BPH, terazosin was effective therapy, whereas finasteride was not, and the combination of terazosin and finasteride was no more effective than terazosin alone. 2 figures. 3 table. 24 references.

provide a framework for treatment choice but leave much room for physician personal opinions. This article reports on a study that identified and quantified determinants of treatment choice for BPH among urologists focusing on urologist treatment preferences. The study population consisted of 670 consecutive patients with BPH, 50 years old or older, newly referred to 1 of 39 urologists in a stratified sample of 13 hospitals throughout The Netherlands. Data on patient characteristics were retrieved from patient questionnaires, medical records, and a urologist questionnaire. Urologist treatment preferences were inventoried using a mailed questionnaire. Among the patient characteristics, maximum flow rate, residual urine, and prostate volume were strongly associated with the probability of surgery and watchful waiting. However, the influence of urologist preferences on actual decisions was also significant. Adjusted for case mix, the differences in low and high preferences revealed a 2.2 times greater probability of surgery. For alpha blockers and finasteride these ratios were 1.8 and 9.4, respectively. An additional independent effect was seen for urologist extent of experience. The authors conclude that the influence of urologist personal preferences on treatment choice in BPH is considerable. Given the different efficacy and side effects of the various treatments, further consensus development is needed to enhance appropriate treatment decisions and eliminate undue costs. The article includes an appendix that reprints the urologist questionnaire. 2 figures. 3 tables. 13 references. (AA-M). •

Benign Prostatic Hyperplasia: Pathogenesis and Medical Therapy Source: Journal of the American Geriatric Society. 39: (12): 1208-1216. December 1991. Summary: Prostate disease is a frequent accompaniment of aging in men. This review article covers the pathogenesis and medical therapy for benign prostatic hyperplasia (BPH). The author focuses on the role of the testis, and particularly dihydrotestosterone (DHT), in the pathogenesis of BPH, since it provides a clear understanding of the rationale for many of the clinical trials to develop medical therapy for BPH. Topics include the relationship between the testis and the prostate, the DHT theory of the pathogenesis of BPH, the estrogen theory of the pathogenesis of BPH, a summary of the endocrine factors relating to this pathogenesis, the non-endocrine factors, treatment of BPH, androgen-withdrawal therapy and surgical castration, medical castration with progestational agents, androgen blockade, medical castration with gonadotropinreleasing hormone (GNRH), the clinical effects of estrogen withdrawal, and the current status of the non-surgical management of BPH. 3 figures. 1 table. 55 references.

Is Transurethral Microwave Thermotherapy an Alternative to Medical Therapy for Patients with Benign Prostatic Hyperplasia? Source: Techniques in Urology. 6(4): 300-306. December 2000. Contact: Available from Raven Press, Ltd. 1185 Avenue of the Americas, New York, NY 10036. (800) 777-2836 or (212) 930-9500. Summary: Scientific evidence supports the safety and efficacy of transurethral microwave thermotherapy (TUMT) as well as medical therapy for the management of patients with benign prostatic hyperplasia (BPH). This article considers the fact that TUMT is increasingly considered as an alternative to medical management with alpha blockers or finasteride in patients with lower urinary tract symptoms of BPH. Enduring clinical benefits have been demonstrated after a single 1 hour microwave treatment session under topical anesthesia, and associated morbidity is low. Optimal results are obtained with the delivery of high thermal doses and accurate targeting of microwave energy. Extensive evidence from randomized clinical trials supports the safety and

efficacy of both microwave treatment and medical management. Randomized clinical trial data directly comparing these two approaches to BPH treatment have only recently become available. These data indicate that greater long term improvements in symptoms, peak urinary flow rates, and quality of life are attained with microwave treatment as compared with alpha blocker therapy. Furthermore, the rate of treatment failure is markedly lower in patients undergoing microwave versus alpha blocker treatment. However, the onset of action with alpha blockers is faster. Limitations of alpha blockers are side effects and lack of efficacy leading to treatment failure in some patients. Maximal effects of finasteride are modest and require months to be demonstrated, although the side effect profile and tolerability of this agent are favorable. Neoadjuvant and adjuvant alpha blocker therapy can accelerate symptom and flow rate improvement after microwave treatment. In contrast to medical management, microwave treatment is highly versatile, allowing patients over a broad range of baseline symptom severities and prostate sizes to be treated with a high probability of success. The author concludes that, compared with medical management, microwave treatment also appears to possess greater versatility, allowing patients who fall within a broad range of baseline symptom severities and prostate sizes to be treated with a high probability of success. 1 table. 40 references. •

Effect of Diabetes on Lower Urinary Tract Symptoms in Patients with Benign Prostatic Hyperplasia Source: Journal of Urology. 163(6): 1725-1729. June 2000.

Summary: Several studies have suggested a specific association between the presence or symptom intensity of benign prostatic hyperplasia (BPH) and diabetes, but no definitive conclusion has thus far been reached. This article reports on a study that examined the intensity of lower urinary tract symptoms in a large cohort of men with BPH, with and without diabetes. The authors then determined whether the alpha 1 adrenoceptor antagonist tamsulosin similarly improved those lower urinary tract symptoms in patients with BPH with or without diabetes. The International Prostate Symptom Score (IPSS), maximum flow rate, and postvoid residual (urine remaining in the bladder after urination) were determined in 9,856 men with clinically diagnosed BPH, of whom 1,290 also had diabetes, at baseline and after a 12 week, open label course of 0.4 mg of tamsulosin daily. Older age and IPSS were independently associated with a statistically significant increase in the odds ratio of having diabetes. Accordingly, men with diabetes had a significantly greater baseline IPSS and smaller maximum flow rate than nondiabetic patients on age adjusted analysis, while residual urine was not significantly altered. Tamsulosin markedly improved lower urinary tract symptoms. The extent of improvement was similar in men with and without diabetes. The authors conclude that the severity of lower urinary tract symptoms in patients with BPH and the likelihood of having diabetes are significantly associated. Within the limitations of an open label, observational study, tamsulosin appears to reduce lower urinary tract symptoms similarly in BPH patients with or without diabetes. 2 tables. 22 references.

Contact: Available from Journal of Urological Nursing, P.O. Box 408, Long Valley, NJ 07853-0408. (908) 852-8789. Summary: The authors of this article describe the use of lasers as an alterative treatment for patients with benign prostatic hyperplasia (BPH). They report on more than two years experience performing laser prostatectomy using the TULIP (transurethral laser prostatectomy) device, with careful follow-up on all of the patients. The authors note that the majority of the currently available lasers utilize the laser's ability to induce coagulative necrosis to achieve the desired clinical effect while minimizing morbidity to the patient. They report on a study that investigated the use of TULIP at 10 clinical sites across the U.S. The results show excellent clinical outcome with minimal morbidity following laser prostatectomy. The authors also stress the need for more extensive cancer screening in patients undergoing TULIP, as compared to those undergoing transurethral resection of the prostate (TURP), in whom a biopsy can be performed postoperatively. 1 table. 8 references. •

Contact: Available from Lippincott Williams and Wilkins. 241 Borough High Street, London, SE1 1GB, UK. +44 (0) 171940-7500. E-mail: [email protected]. Summary: The choices for minimally invasive treatments for patients with benign prostatic hyperplasia (BPH) has increased during the past decade. This article reviews these treatment options. The energy sources used range from microwaves and radiofrequency waves to high intensity focused ultrasound, laser vaporization, laser coagulation, laser resection, and electrosurgical techniques. The authors review the particular advantages and disadvantages of each of these devices by summarizing the findings of recent, clinically significant studies. At present, the most intensively studied techniques are interstitial laser coagulation, holmium laser resection, and new approaches to transurethral electrosurgery. The authors conclude that there is now enough data available to allow comparisons between these minimally invasive techniques and the gold standard for treatment, transurethral resection of the prostate (TURP). Although the subjective response after TURP and minimally invasive procedures is comparable, improvements of flow and urodynamic (measurement of urinary flow and pressure during urination) parameters are nearly always better after TURP. Failure rates requiring reintervention are considerably higher than after TURP and many of these procedures have anatomical limitations. Minimally invasive procedures lead to a shift of the morbidity (complications) from the intraoperative time, which is reduced, to the postoperative phase. The postoperative phase can be characterized by a prolonged urinary retention, significant dysuria (pain on urination), and nocturia (urination at night). The authors note that improvements in TURP are resulting in a less invasive procedure for TURP itself, and improvements in perioperative care and anesthesia are reducing the risk of postoperative complications. 2 figures. 4 tables. 64 references (21 abstracts).

Summary: The choices of minimally invasive treatment modalities for patients with benign prostatic hyperplasia (BPH) has increased steadily during the past decade. The energy sources used range from microwaves and radiofrequency waves to high intensity focused ultrasound, with laser vaporization or coagulation or resection and electrosurgical techniques. This article reviews the large amount of data available and draws some conclusions concerning the present role of the 'gold standard' TURP (transurethral resection of the prostate) among the minimally invasive procedures. Although the subjective response after TURP and other minimally invasive procedures is comparable, improvements of flow and urodynamic parameters usually are more pronounced after TURP. Failure rates requiring reintervention (usually TURP) are considerable. Minimally invasive procedures lead to a shift of morbidity from the intraoperative phase, which is reduced (risk of bleeding, TUR syndrome, transfusion) to the postoperative phase. This postoperative period is characterized by prolonged urinary retention, significant dysuria (painful urination), and nocturia (urination at night). Recent advances in electrosurgical techniques, such as band TURP loops that facilitate coagulation due to the longer contact time between the electrode and the tissue, have the potential to convert TURP into a less invasive procedure. Finally, high energy TUMT (transurethral microwave thermotherapy) seems to offer a truly minimally invasive treatment combining efficacy and the need for topical anesthesia only. However, due to a lack of homogeneity of criteria for patient recruitment, parameters of evaluation, and adequate followup, accurate guidelines for appropriate patient management have not yet been established. 93 references. •

of less invasive alternatives. Microwave therapy is one of the most explored forms of heat-induced therapy of the prostate. This article provides an overview of microwave therapy and explains what the nurse and patient should be aware of as treatment decisions are made. The authors describe two different forms of microwave therapy: hyperthermia and transurethral thermotherapy. The authors focus on the recently approved transurethral thermotherapy and related patient implications. This procedure involves heating the prostate gland transurethrally to destroy prostatic tissue through tissue necrosis. A special microwave catheter placed in the patient's urethra carries the microwaves and a cooling system of sterile water, which keeps the urethral area cooler than 50 degrees Centigrade. This procedure is completed with a single, 1 hour treatment. Compared to transurethral prostatectomy, microwave therapy is significantly less costly to the hospital and patient because it is an outpatient procedure that does not require general anesthesia, it is a short procedure, and it requires minimal staffing. 3 figures. 12 references.

Evaluation of Benign Prostatic Hyperplasia Treatments: How Can We Improve the Outcome Measure and Success Criteria? Source: European Urology. 32(Supplement 2): 38-41. July 1997. Contact: Available from S. Karger Publishers, Inc. 26 West Avon Road, P.O. Box 529, Farmington, CT 06085. Summary: This article considers the evaluation of treatments for benign prostatic hyperplasia (BPH), a situation that is complicated by a number of interdependent factors. The evaluation of the individual patient is influenced by the risk-to-benefit ratio and health-related quality of life (QOL); and this, in turn, is interrelated with the evaluation of therapeutic options. Current outcome measures include subjective measurements (symptom scores and patient reports) and objective measurements (uroflow and prostate volume). In order to improve outcome measures it is important to use health-related QOL scales and symptom and bother-associated (level of annoyance) scores. In addition, the patient should complete frequency and volume charts and possibly use home flowmetry; transitional zone measurements may also play a role in finding a better treatment strategy. It is important to consider the adverse effects and complication rates of invasive and pharmacological treatments (including their influence on QOL) and economic factors such as the cost of treatment, the cost of following guidelines, and the durability and failure rate associated with treatment. The author concludes that, in order to manage the increasing number of BPH patients who seek care effectively, it is important to share care provision between urologists and general practitioners, but this will require improved guidelines, better data, and better outcome measurements. 1 table. 12 references.

Benign Prostatic Hyperplasia: Natural Evolution Versus Medical Treatment Source: European Urology. 32(Supplement 2): 34-37. July 1997. Contact: Available from S. Karger Publishers, Inc. 26 West Avon Road, P.O. Box 529, Farmington, CT 06085. Summary: This article considers the topic of natural evolution versus medical treatment for benign prostatic hyperplasia (BPH). The author stresses that the epidemiology and natural evolution of the condition must be taken into consideration. The incidence of BPH increases with age; it is thought that about 75 percent of men over 50 years of age suffer from some symptoms commonly associated with BPH. There are also differences in the incidence of BPH among various racial and ethnic groups. For example, it is considerably less common among Japanese men compared with Caucasian men. Evidence from prospective studies, retrospective studies, and the placebo arms of randomized, controlled studies regarding the natural evolution of BPH suggests that a strategy of 'watchful waiting' may be considered as a treatment option, since the majority of patients do not show a worsening of symptoms over time. However, the chance for improvement of symptoms and the degree of symptom improvement has been shown to be higher with alpha1-blocker therapy than with 'watchful waiting.' As both symptoms and treatment have an impact on the patient's quality of life, there is now a strong case for involving the patient in making quality of life decisions based on his own preferences and attitudes. 2 figures. 2 tables. 14 references.

Summary: This article describes a study that evaluated the long term efficacy and safety of once daily tamsulosin at 0.4 or 0.8 milligrams (mg), a unique selective alpha1Aadrenoceptor antagonist, in patients with benign prostatic hyperplasia (BPH). The study extended a 13 week, Phase III multicenter placebo controlled, double blind outpatient trial for an additional 40 weeks. Of 618 patients, 418 continued into the extension phase on the same double blind medication and dose. The primary efficacy parameters were total American Urological Association (AUA) symptom score and maximum urinary flow (Qmax). The mean changes in AUA symptom score from baseline to end point were statistically significant in all groups. Significant improvements were observed for both tamsulosin groups but not for the placebo group. The statistically significant improvements from baseline in efficacy parameters observed for each tamsulosin group at the end of the 13 week Phase III trial were maintained during the long term extension phase. Tamsulosin at both dosages was well tolerated as maintenance therapy. Clinically significant orthostatic hypotension (low blood pressure) was not observed. Vital sign changes in either hypertensive or normotensive patients were not clinically significantly different across the three groups. The authors conclude that tamsulosin once daily at 0.4 or 0.8 mg was shown to be effective, safe, and well tolerated in the target BPH population during long term use. 1 appendix. 2 figures. 2 tables. 11 references.

Benign Prostatic Hyperplasia

Summary: This article describes treatment with alpha1-adrenergic blockers as a reasonable alternative to surgery for patients with symptomatic benign prostatic hyperplasia (BPH). The author notes that alpha blockers may also be useful as an adjunct to finasteride in the treatment of this disorder. Topics include the drugs' mechanism of action; pharmacokinetics; efficacy; adverse effects; drug interactions; indications; clinical presentation; and treatment. The author stresses that pretreatment evaluation is essential to ensure that the patient does not have an infection, prostate cancer, or another serious cause of the prostatic symptoms. Side effects can be minimized by administering the medication at night and reversed by discontinuing the drug. In more than 50 percent of patients, treatment with alpha blockers results in objective and subjective symptomatic relief. 1 table. 13 references. (AA-M). •

Summary: This article describes treatments for benign prostatic hyperplasia (BPH) among men participating in the Olmsted County study of urinary symptoms and health status among men during 10,000 person-years of followup. A cohort of 2,115 men (40 to 79 years old) was randomly selected from an enumeration of the Olmsted Country, Minnesota, population (55 percent response rate). Participants completed a previously validated baseline questionnaire to assess symptom severity and voided into a portable urometer. A 25 percent random subsample underwent transrectal sonographic imaging of the prostate to determine prostate volume and measurement of serum prostate specific antigen (PSA). Followup included retrospective review of community medical records and completion of a biennial questionnaire to determine the occurrence of medical and surgical treatment for BPH in the subsequent 6 years. During more than 10,000 person-years of followup, 167 men were treated, yielding an overall incidence of 16.0 per 1,000 person-years. There was a strong age related increase in risk of any treatment from 3.3 per 1,000 person-years for men 40 to 49 years old, to more than 30 per 1,000 person-years for those men 70 years old or older. Men with moderate to severe symptoms, depressed peak urinary flow rates, enlarged prostate, or elevated serum PSA had about 4 times the risk of BPH treatment as those who did not. The authors conclude that the data demonstrate that treatment for BPH is common in elderly men with nearly 1 in 4 receiving treatment in the eighth decade of life (the authors note that repeat contact and availability of urological measurements during the study period may have influenced treatment decisions in this cohort). Furthermore, the data suggest that men with moderate to severe lower urinary tract symptoms, impaired flow rates, or enlarged prostates are more likely to undergo treatment, with increases in risk of similar magnitude to those associated with adverse outcomes, such as acute urinary retention. 3 tables. 1 figure. 37 references.

Updated Patient Information for Treatment of Benign Prostatic Hyperplasia: A Permanent Challenge Source: European Urology. 32(Supplement 2): 42-44. July 1997. Contact: Available from S. Karger Publishers, Inc. 26 West Avon Road, P.O. Box 529, Farmington, CT 06085. Summary: This article discusses the use of patient education and information provision as a crucial part in the decision-making process for treating benign prostatic hyperplasia (BPH). The author states that, ideally, a decision analysis should be performed in order to provide patient information and enhance decision-making procedures in BPH. The steps associated with a decision analysis include creating a decision tree, identifying decision alternatives, quantifying the potential outcomes, and weighing the potential outcomes according to the patients' requirements. However, doctors have their own individual experience and information on treatment from a wide variety of sources, e.g., journals, conferences, and industry. Patients, in contrast, are typically informed by the popular media, friends, and relatives. Updated patient information for the treatment of BPH therefore remains a permanent challenge. Each patient also has an individual acceptance level of his symptoms, an individual tolerance for therapy, and an individual approach to medication or surgery. The doctor may have novel experience with new drugs and instrumental procedures and his own individual availability of treatment options. The doctor must always take the cost-effectiveness of a treatment into consideration. 2 tables. 2 references. (AA-M).

Tamsulosin: A Uroselective Drug in the Management of Benign Prostatic Hyperplasia Source: Today's Therapeutic Trends: The Journal of New Developments in Clinical Medicine. 16(2): 119-137. 2nd Quarter 1998. Contact: Available from Communications Media for Education, Inc. Post Office Box 712, Princeton Junction, NJ 08550. Summary: This article discusses the use of tamsulosin in the management of benign prostatic hyperplasia (BPH). Tamsulosin (Flomax), the first of a new class of alpha blockers, demonstrates preferential selectivity for the 1A-receptor subtype which predominates in prostatic smooth muscle. Therefore, this agent is optimally effective in treating the symptoms of BPH, while reducing extraprostatic effects and thus the incidence of treatment related adverse reactions. These adverse reactions were more often encountered with the use of earlier alph-receptor antagonists. Overall, tamsulosin has a number of significant advantages. Its long duration of action allows for once a day dosing within a range of 0.4 to 0.8 mg. Its therapeutic effect, as indicated by a more than 30 percent increase in peak urinary flow rate, is achieved in over 50 percent of patients receiving tamsulosin therapy. Moreover, the therapeutic effect of tamsulosin is realized as early as 2 to 3 weeks after reaching the optimum dosage. In addition to controlling the irritative symptoms of BPH, tamsulosin dosage can be titrated to achieve the desired reduction in obstructive urinary tract symptoms, such as a weak urinary stream, hesitancy, straining, and incomplete voiding. If necessary, the dose can also be decreased to reduce the incidence of any untoward side effects. The occurrence of cardiovascular system effects that may be seen with earlier alph blocking agents is less of a concern due to tamsulosin's demonstrable uroselective activity. Finally, as any pharmacotherapy for BPH must be administered indefinitely to maintain the desired therapeutic effect, the favorable long term clinical experience with tamsulosin treatment is particularly significant. 2 tables. 95 references.

of controlled heat at high temperatures to safely destroy the excess prostatic tissue which can cause the symptoms of BPH. Heat is delivered to the prostate by using a small microwave treatment catheter that is inserted into the urethra. The inclusion of a cooling system in the microwave applicator allows for deeper penetration of the power, while eliminating local pain and urethral destruction. Because the urethra is constantly cooled and protected, the treatment is anesthesia free, is performed on an outpatient basis, and does not have the side effects associated with other treatments. The benefit of the treatment begins to be felt 6 to 8 weeks following the procedure. This gradual improvement is due to the steady absorption by the body of treated prostate tissue. One sidebar describes the technique of watchful waiting as a treatment option for prostate cancer. 1 figure. (AA-M). •

Contact: Available from American Academy of Family Physicians. 8880 Ward Parkway, Kansas City, MO 64114-2797. (800) 274-2237. Summary: This article outlines the medical and surgical options used for the treatment of benign prostatic hyperplasia (BPH), options which have expanded in recent years. Saw palmetto, the most widely used complementary medication, is less effective than standard medical therapy but has fewer side effects. Although nonselective alpha blockers provide rapid relief of symptoms and are relatively inexpensive, they can cause dizziness and orthostatic hypotension. These effects occur less often with tamsulosin, a more selective alpha blocker. Finasteride, a 5 alpha-reductase inhibitor, slowly reduces prostatic volume but is not as effective as alpha blockers, especially in men with a smaller prostate. Dutasteride, a new 5 alpha-reductase inhibitor, has recently been labeled for the treatment of BPH. Surgery may be appropriate initial treatment in patients with severe symptoms who are not at high risk for complications. Surgery may also be indicated in patients who have failed medical therapy or have recurrent infection, hematuria (blood in the urine), or renal (kidney) insufficiency. Transurethral resection of the prostate (TURP) is effective in most patients, but it carries some risk of sexual dysfunction, incontinence, and bleeding. Surgical procedures that use thermal microwave or laser energy to reduce hyperplastic prostate tissue have recently become available. In general, the newer procedures are less expensive than transurethral resection of the prostate and have fewer complications; however, the need for retreatment is somewhat greater with these less invasive techniques. 1 figure. 2 tables. 29 references.

Contact: Available from Lippincott Williams and Wilkins. 241 Borough High Street, London, SE1 1GB, UK. +44 (0) 171940-7500. E-mail: [email protected]. Summary: This article provides information on the epidemiology, etiology, classification, pathophysiology, symptoms, diagnosis, and treatment of benign prostatic hyperplasia (BPH). The understanding and therapy of BPH has become more complex recently. The molecular mechanisms and growth factors involved in BPH need to be elucidated in the new millennium. The current classification of disease reflects the varied pathophysiologic mechanisms causing lower urinary tract symptoms (LUTS). In addition, symptom scores have improved evaluation of men with BPH, yet bothersomeness' and health related quality of life' should be better recognized as significant outcome parameters. Clinical evaluation with laboratory markers specific for BPH or LUTS is currently inadequate. Yet, urodynamic evaluation should remain an important aspect of evaluation to guide selection of therapy. Recently, medical therapy has expanded to include uroselective alpha blockade and phytotherapy, yet more research is needed. The most significant growth field, however, is in minimally invasive therapies of the prostate. Long term comparative prospective multicenter studies are needed to properly evaluate the outcomes of new technologies compared to traditional procedures that are considered standard of care. 32 references.

Comparison of Transurethral Surgery with Watchful Waiting for Moderate Symptoms of Benign Prostatic Hyperplasia Source: New England Journal of Medicine. 332(2): 75-79. January 12, 1995. Summary: This article reports on a multicenter randomized trial that compared transurethral resection of the prostate (TURP) with watchful waiting in men with moderate symptoms of benign prostatic hyperplasia (BPH). Of 800 men over the age of 54 years who were screened between July 1986 and July 1989, 556 were studied (280 in the surgery group and 276 in the watchful-waiting group). Patients' symptoms and the degree to which they were bothered by urinary difficulties were measured with standardized questionnaires and medical evaluations; treatment failure was the primary outcome measure. The researchers conclude that, for men with moderate symptoms of BPH, surgery is more effective than watchful waiting in reducing the rate of treatment failure and improving genitourinary symptoms. Watchful waiting is usually a safe alternative for men who are less bothered by urinary difficulty or who wish to delay surgery. 1 figure. 3 tables. 15 references. (AA-M).

Summary: This article reports on a randomized, placebo controlled trial that tested the effects of a saw palmetto herbal blend in men with symptomatic benign prostatic hyperplasia (BPH). The authors randomized 44 men aged 45 to 80 years old with symptomatic BPH into a trial of a saw palmetto herbal blend versus placebo. Results showed both saw palmetto herbal blend and placebo groups had improved clinical parameters with a slight advantage in the saw palmetto group (not statistically significant). Neither prostate specific antigen (PSA) nor prostate volume changed from baseline. Prostate epithelial contraction was noted, especially in the transition zone, where percent epithelium decreased from 17.8 percent at baseline to 10.7 percent after 6 months of saw palmetto herbal blend. Histological studies showed that the percent of atrophic glands increased from 25.2 percent to 40.9 percent after treatment with saw palmetto herbal blend. The mechanism of action appeared to be nonhormonal, but it was not identified by tissue studies of apotosis, cellular proliferation, angiogenesis, growth factors, or androgen receptor expression. The authors noted no adverse effects of saw palmetto herbal blend. When the study was no longer blinded, 41 men elected to continue therapy in an open label extension. The authors conclude that saw palmetto herbal blend appears to be a safe, highly desirable option for men with moderately symptomatic BPH. Saw palmetto herbal blend therapy was associated with epithelial contraction, especially in the transition zone, indicating a possible mechanism of action underlying the clinical significance detected in other studies. 2 appendices. 4 figures. 4 tables. 23 references.

Summary: This article reports on a study in which the authors compared the Health Utility Index (HUI), EuroQol (EQ-5D), and time trade-off methods to identify the most suitable technique for collecting preference data in a clinical trial of patients with benign prostatic hyperplasia (BPH). In the study, a total of 29 men with symptomatic BPH were interviewed by a single trained interviewer who collected demographic data and administered EQ-5D and time trade-off questionnaires. Participants self administered the other tests. Although mean utility values for HUI, EQ-5D, and 1 year time trade-off were similar, only utility values elicited using time trade-off with a 1 year time frame significantly correlated with symptom scores. All participants indicated that the HUI and EQ-5D were appropriate for assessing BPH, while approximately 10 percent considered time trade-off questions irrelevant. Average completion time for the HUI, time trade-off, and EQ-5D was 31, 25, and 10 minutes, respectively. 1 figure. 2 tables. 16 references.

Summary: This article reports on a study that established the prevalence and bothersomeness of symptoms and their impact on well being in a large group of strictly selected men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). Included in the study were 475 consecutive men who met the criteria of the International Consensus Committee on BPH and who voided more than 150 milliliters during uroflowmetry. International Prostate Symptom Scores (IPSS) and quality of life score were determined. The symptoms with the highest prevalence were weak urinary stream, frequency and urgency. Urgency, nocturia (urinating at night), and hesitancy were the most bothersome symptoms. Patients were only discouraged from performing normal daily activity when the symptom index exceeded 20. Incomplete emptying and frequency bothersomeness correlated strongly, and weak urinary stream and hesitancy bothersomeness correlated weakly with all health and quality of life domains. 3 figures. 4 tables. 18 references.

Doxazosin for Benign Prostatic Hyperplasia: Long-Term Efficacy and Safety in Hypertensive and Normotensive Patients Source: Journal of Urology. 157(2): 525-530. February 1997. Summary: This article reports on a study to evaluate the sustained efficacy and safety of doxazosin for longterm treatment (up to 48 months) of normotensive and hypertensive patients with benign prostatic hyperplasia (BPH). A total of 272 normotensive and 178 mildly to moderately hypertensive men entered a longterm extension study of doxazosin therapy (1 to 8 and 1 to 12 mg. 1 time daily, respectively) for BPH following participation in double-blind, placebo controlled studies. The starting dose of doxazosin was 1 mg. with upward titrations at 2-week intervals to a stable, efficacious and welltolerated dose. At the time of data analysis, patients had received between 1 and 48 months of stable dose doxazosin therapy. At the end point analysis, doxazosin treatment resulted in significant increases above baseline in maximum and average urinary flow rates. As assessed by the patient, total, obstructive, and irritative BPH symptoms also improved significantly with doxazosin treatment. Sustained blood pressure decreases with doxazosin were statistically and clinically significant in hypertensive patients. Blood pressure decreases in normotensive patients were not clinically significant. Changes in heart rate were not significant. Doxazosin was well tolerated with almost 90 percent of adverse experiences considered mild or moderate in severity. The most common adverse events were dizziness, headache, and fatigue in normotensive and hypertensive patients. 4 figures. 6 tables. 27 references. (AA-M).

Summary: This article reports on a study undertaken to compare the efficacy and safety of finasteride (5 milligrams) in older (65 years old or older) versus younger (45 to younger than 65 years old) men with benign prostatic hyperplasia (BPH). The Proscar Long Term Efficacy and Safety Study (PLESS) was a 4 year, randomized, double blind, placebo controlled trial assessing the safety and efficacy of finasteride 5 milligrams in 3,040 men aged 45 to 78 years old with symptomatic BPH, enlarged prostates, and no evidence of prostate cancer. The endpoints included urinary symptoms, prostate volume, occurrence of acute urinary retention, or BPH related surgery, and safety. In both age groups, finasteride treatment led to a 51 percent reduction in the relative risk for acute urinary retention (inability to urinate because of blockage) or BPH related surgery, a significant and durable improvement in symptoms score, and a significant and sustained reduction in prostate volume. Within each age cohort, no significant differences were found between the placebo and finasteride treated patients in the incidence of cardiovascular adverse events. Significant differences were evident between the placebo and finasteride groups in the incidence of the typical, known, drug related adverse events, but no specific differences were associated with age. No drug interactions of clinical importance were observed in the finasteride treated patients. The results demonstrate that finasteride is highly effective in improving symptoms and reducing prostate volume in many men and in reducing the risk of acute urinary retention and BPH related surgery. 2 figures. 3 tables. 16 references. •

Practice Trends in the Diagnosis and Management of Benign Prostatic Hyperplasia in the United States Source: Journal of Urology. 154(1): 205-206. July 1995.

Summary: This article reports on a survey designed to ascertain practice trends in the diagnosis and management of benign prostatic hyperplasia (BPH) in the United States. In August 1994, a random sample of 514 American urologists was surveyed by the Gallup Organization regarding practice patterns for BPH. The survey revealed that 99 percent of the respondents were aware of and used the American Urological Association (AUA) symptom score index, and that 21 percent of these respondents had altered their diagnosis and management strategies because of its existence. The authors conclude that therapeutic recommendations of the respondents based upon AUA symptom score index severity parallel the recently announced Federal Agency for Health Care Policy and Research BPH guidelines. 3 tables. 3 references.

Contact: Available from Raven Press, Ltd. 1185 Avenue of the Americas, New York, NY 10036. (800) 777-2836 or (212) 930-9500. Summary: This article reports on water induced thermotherapy (WIT), administered by the Thermoflex System, a new, minimally invasive technique for the treatment of benign prostatic hyperplasia (BPH). The Thermoflex System consists of an extracorporeal (outside the body) heat source and a proprietary closed loop catheter system. Water, heated to 60 degrees Centigrade, is continuously circulated through the catheter to a treatment balloon, which conducts thermal energy to targeted prostatic tissue. The combination of heat and compression reduces the heat sink effect of the circulating blood, thus enhancing the thermal energy transfer to the compressed tissue.

WIT treatment is performed using only topical urethral anesthetic, in a single 45 minute session. The 2 year follow up data from a European multicenter study consisting of 125 patients showed an improvement in peak urine flow of 87.4 percent from baseline and in the International Prostate Symptom Score (IPSS). Patient tolerance of WIT was rated as excellent or good in 91.8 percent of the procedures. The authors conclude that WIT is effective, simple, and inexpensive; has few side effects; and does not need special probes to monitor prostate or rectum temperature; thus, it can be used in hospitals, outpatient clinics, and doctors' offices. 7 figures. 1 table. 10 references. •

Summary: This article reviews recent advances in transurethral microwave thermotherapy (TUMT), a promising, minimally invasive treatment for patients with complaints related to benign prostatic hyperplasia (BPH). The results of phase II studies and placebo control studies suggest real therapeutic benefit for certain patient groups who undergo this treatment. A number of reports have appeared that confirm the thermotherapy principle, add to the knowledge of patient selection, and provide data to suggest that the treatment is durable. Consistently, TUMT appears to be a remarkably safe procedure, and refinement in patient selection will confirm a place for this treatment between medical and surgical alternatives for BPH. The single session, outpatient office-based procedure, which does not require general anesthesia, continues to be an attractive alternative for patients with symptoms of moderate to moderately severe BPH. 1 figure. 4 tables. 23 abstracts.

relieve or eliminate the lower urinary tract symptoms (LUTS) caused by prostatic growth and bladder outlet obstruction. They seek to accomplish this by arresting prostatic growth and reducing prostatic size, or by diminishing the smooth muscle tone of the prostatic and proximal urethra. Medical therapy must be limited to those patients who do not have significant obstructive uropathy caused by bladder outlet obstruction. The authors discuss two classes of drugs, the 5 alpha reductase blockers and the adrenergic antagonists, both of which provide acceptable efficacy and tolerable side effects. Although initial clinical experiences favor the efficacy of a combination of alpha reductase blockers and an alpha adrenergic blocking agent over monotherapy, no well controlled clinical trial has been completed to prove or disprove this clinical impression. The authors call for research elucidating the relationship between bladder outlet obstruction and LUTS, and the natural history of BPH, in order to better define the role of medical therapy in controlling or preventing the adverse effects caused by BPH. 2 figures. 14 references. •

Benign Prostatic Hyperplasia

Summary: This entry from a monograph on geriatric urology explores the most common cause of outlet obstruction in the male geriatric population, benign prostatic hyperplasia (BPH). The prevalence, pathophysiology, and natural history of BPH are discussed, along with the work-up and indications for medical or surgical intervention. The authors also focus on the medical and surgical options now available for the management of BPH. The options include 5-alpha-reductase inhibitors, other hormonal agents, alpha-adrenergic antagonist drugs, transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), transurethral electrovaporization of the prostate, laser prostatectomy, transurethral balloon dilation of the prostate, prostatic stents, high-intensity focused ultrasound, microwave therapy, transurethral microwave thermotherapy (TUMT), and transurethral needle ablation of the prostate (TUNA). 4 figures. 1 table. 96 references.

Saw Palmetto Extracts for Treatment of Benign Prostatic Hyperplasia: A Systematic Review Source: JAMA. Journal of the American Medical Association. 280(18): 1604-1609. November 11, 1998. Summary: This journal article reviews the research on the efficacy and safety of saw palmetto extract (Serenoa repens) in men with symptomatic benign prostatic hyperplasia (BPH). A comprehensive search of the literature identified 18 randomized controlled trials involving 2,393 men who met inclusion criteria. Studies were included if the participants had symptomatic BPH, the intervention was a preparation of Serenoa repens alone or in combination with other phytotherapeutic agents, a control group received a placebo or other pharmacological therapies for BPH, and the treatment duration was at least 30 days. Results from doctor and participant assessments showed that Serenoa repens was superior to a placebo and comparable with finasteride in improving urinary tract symptom scores, nocturia, peak and mean urine flow rates, and residual urine volume. Adverse effects due to Serenoa repens generally were mild and comparable with a placebo. Erectile dysfunction was more common with finasteride (4.9 percent) than with S repens (1.1 percent). The withdrawal rates in men receiving Serenoa repens, a placebo, and finasteride were 9.1 percent, 7 percent, and 11.2 percent, respectively. The authors conclude that Serenoa repens appears to improve urologic symptoms and flow measures in men with BPH; its efficacy is similar to that of finasteride but with fewer adverse effects. The article has 4 figures and 51 references.

FDA Public Health Notification: Serious Injuries from Microwave Thermotherapy for Benign Prostatic Hyperplasia Source: AUA News. 6(1): 20. January-February 2001. Contact: Available from Lippincott Williams and Wilkins. 351 West Camden Street, Baltimore, MD 21201. (410) 528-4000. Website: lww.com. Summary: This news article offers a Food and Drug Administration (FDA) public health notification on the incidence of serious injuries from microwave thermotherapy for benign prostatic hyperplasia (BPH). The notification also provides information that can help avoid these complications. Although the use of microwave thermotherapy for the treatment of BPH has been demonstrated to be safe and effective, and more than 25,000 procedures have been performed, the FDA is concerned about some unexpected procedure related complications that have occurred since the marketing of these devices. Since 1996, the FDA has received reports of 16 thermal injuries related to microwave thermotherapy. Of these, 10 resulted in fistula (an abnormal passage) formation and 6 resulted in clinically significant tissue damage to the penis or urethra. These injuries may not be apparent at the time of treatment and may take hours or days to develop. The reported injuries have required colostomies, partial amputation of the penis, or other therapeutic interventions. The report outlines the factors that may have contributed to the injuries noted and offers recommendations for preventing those injuries. Continued physician monitoring of the procedure is the most crucial aspect in preventing injuries. Readers are encouraged to copy and distribute this information freely.

Urodynamic Effects of Various Treatment Modalities for Benign Prostatic Hyperplasia Source: Journal of Urology. 158(6): 2034-2044. December 1997. Summary: This review article covers the effects of various treatments for benign prostatic hyperplasia on urethral resistance. Articles that reported pretreatment and

26

Benign Prostatic Hyperplasia

posttreatment values of relevant urodynamic parameters were analyzed. Average before and after treatment values of maximum flow rate and detrusor pressure at maximal flow rate for every study were plotted and classified as obstructed, equivocal, or nonobstructed. Average values of maximum flow rate and detrusor pressure at maximal flow rate were calculated for the total number of patients treated by a certain modality. Based on this analysis, the rank order of urodynamic efficacy showed that open prostatectomy is more effective in reducing urethral resistance than is transurethral prostatectomy. These treatments diminish obstruction better than laser treatment or transurethral incision of the prostate, which again are more effective than balloon dilation, alpha-blockers, or transurethral microwave thermotherapy. Finally, androgen deprivation performs better than placebo treatment. The author concludes that the rank order of urodynamic efficacy as determined in this analysis shows a high level of agreement with reported rank order of symptomatic efficacy of various modalities. After placebo treatment there is no significant change in urethral resistance. The author notes that these results indicate that pressure-flow studies are a sensitive way to compare active to placebo treatment and that pressure-flow studies have excellent long-term reproducibility. 7 figures. 4 tables. 85 references.

Cliggott Publishing Company, 55 Holly Hill Lane, Box 4010, Greenwich, CT 06831-0010. Summary: Voiding dysfunction in men is often caused by benign prostatic hyperplasia (BPH), but the differential diagnosis also includes prostate cancer and nonprostaterelated problems. This article provides guidelines to physicians for the diagnosis and treatment of BPH. A thorough patient history covers not only the classic symptoms, such as decreased force of urinary stream, but also identifies medical conditions that can affect the urinary tract, including diabetes. Readers are advised, when performing the digital rectal examination, to be sure to press into the substance of the prostate; otherwise, areas of induration and nodularity may be missed. Most prostate nodules are not exophytic lumps that project into the lumen of the rectum. Diagnostic tests used include urinalysis; measurement of serum creatinine and prostate-specific antigen (PSA); and transrectal ultrasonography. In selected patients, urodynamics or video urodynamics helps differentiate the various causes of voiding dysfunction. Treatment options discussed for BPH include watchful waiting, androgen deprivation therapy (finasteride), alpha-blockers (terazosin and doxazosin), and surgery. The absolute indications for therapy are deterioration of renal function, hydronephrosis, bladder

Project Title: ACTION OF HORMONES ON PROTEIN AND RNA METABOLISM Principal Investigator & Institution: Mcphaul, Michael J.; Professor; Internal Medicine; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2002; Project Start 01-JUN-1976; Project End 30-JUN-2005 Summary: The androgen receptor plays a critical role in the development of the male phenotype and in the regulation of homeostatic processes, such as spermatogenesis. In addition, alteration of androgen receptor function have been implicated in the pathogenesis and progression of a number of disease states, including spinal bulbar muscular atrophy and prostate cancer. A large body of experimental work has defined the functional domains of the androgen receptor and identified a number of structural lesion that contribute to alterations of androgen receptor function. The present application seeks to build upon this foundation to identify the proteins that mediate the function of the androgen receptor in controlling gene expression. Three specific aims are proposed: 1) Extension of prior work that has identified two proteins (RFG/ELE1/ARA70 and 23-3) that interact with the ligand- bound androgen receptor. Experiments are outlined to define the genesis and location of potential isoforms and the roles that each plays in the normal function of the human AR. Experiments to produce and characterize mice with conditional disruptions of the RFG/ELE1/ARA70 gene are proposed. 2) Characterization of proteins that have been identified on the basis of their ability to interact with the androgen receptor protein in two-hybrid screens using the intact AR-A to screen a randomly primed cDNA library. 3) Biochemical characterization of proteins that associate with the androgen receptor using a novel immuno purification method to purify native AR expressed in mammalian cells. Extensions of these studies are proposed to permit an analysis of the effects that thee type of ligand, nature of the

The male reproductive tract offers many advantages for studies of age-related phenomena, including: 1) experimental manipulation of the tests/epididymides is unlikely to cause death or morbidity; 2) much is known about the regulation of the male tract; and 3) the male reproductive system is an excellent model for generalized aging because it is possible to study, at once, the influence of age on cells that have different proliferative capacities and are at different stages of differentiation. Thus, there are cells that are proliferating rapidly by mitosis (spermatogonia, prostatic epithelia cells), undergoing meiosis (spermatocytes), permanently postreplicative (Sertoli cells), slowly turning over (Leydig cells), differentiating (spermatids), terminally differentiated (spermatozoa), and exquisitely sensitive to hormones and to changes in testicular function (epididymal and prostatic epithelia cells). In the rat, as in the human, striking changes occur with aging, including reduced secretion of testosterone, diminished germ cell production, reduced numbers of testicular and epididymal sperm, atrophy of the seminiferous epithelium, and increased sensitivity of the prostate gland to androgens. The major objectives of this program project application are to elucidate the critical structural and functional changes associated with aging of Leydig (Drs. Zirkin and Wright, Project 1), prostatic (Dr. Brown, Project 2), Sertoli/germ (Drs. Zirkin and Wright, Project 1), spermatozoal (Dr. Robaire, Project 3) and epididymal (Dr. Robaire, Project 3) cells, and to determine the mechanism by which such changes occur.

Project Title: AGING AND PROSTATE GROWTH Principal Investigator & Institution: Dahiya, Rajvir; Professor and Director; Northern California Institute Res & Educ 4150 Clement Street (151-Nc) San Francisco, Ca 941211545 Timing: Fiscal Year 2002; Project Start 01-SEP-1998; Project End 30-NOV-2003 Summary: The main goal of this proposal is to investigate the molecular mechanisms of prostate growth in aging. The rationale for this proposal is that the mechanisms of neoformation of ductal-acinar tissue during the pathogenesis of benign prostatic hyperplasia (BPH) is similar (if not identical) to the process of ductal-acinar growth and

development occurring during the organogenesis of the prostate in fetal and pubertal periods. This proposal is based on the hypothesis that the age- dependent endocrine control of prostatic cell growth is regulated by mesenchyme-epithelial cell interactions mediated by the local production and action of growth factors (KGF, TGFa, and TGFb). Based upon preliminary experiments, TGFa and KGF may up-regulate and TGFb downregulate the prostatic epithelium growth. This hypothesis will be tested through pursuit of the following specific aims. 1. Analysis of paracrine mechanisms in the regulation of rat fetal prostatic growth and differentiation. Under this specific aim, rat fetal prostates (different ages) will be studied to determine growth kinetics, ductal morphogenesis, expression of differentiation markers and expression of KGF, TGFa and TGFb and their receptors. Specific Aim number 2. Analysis of the growth promoting and morphogenetic effects of rat urogenital sinus mesenchyme (rat UGM) on growth-quiescent adult rat prostatic epithelium. Under this specific aim we will test the hypothesis that rat UGM can induce the growth and differentiation of growth-quiescent adult rat prostatic epithelium. To test this hypothesis, rat UGM will be associated with rat prostatic epithelium from adult rats (age 3, 6, 12, 18 and 24 months) and the resultant tissue recombinants will be grown in kidney capsules of male athymic nude mice and will be characterized for growth, differentiation and expression of KGF, TGFa and TGFb and their receptors. Specific Aim number 3. Analysis of the inter- relationships between growth factor families during normal and impaired prostatic epithelial growth. Under this specific aim, we hypothesize that there is a complex interaction between androgen action and growth factors. Indeed, for some systems it has been shown that the actions of one growth factor may be mediated by other downstream signaling growth factors. To dissect this complex interplay between growth factors, various transgenic knockout mice will be utilized. The goal of this experiment is to elucidate the linkage between different growth factor pathways employing chimeric rat-mouse prostatic tissue recombinants.

Project Title: AGING AND PROSTATIC HYPERPLASIA IN TRANSGENIC MICE Principal Investigator & Institution: Chatterjee, Bandana; Professor; Cellular & Structural Biology; University of Texas Hlth Sci Ctr San Ant 7703 Floyd Curl Dr San Antonio, Tx 78229 Timing: Fiscal Year 2003; Project Start 01-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): Age-associated benign prostatic hyperplasia (BPH) is a major health problem of elderly men. The molecular etiology of BPH is complex and not clearly understood. Chronic influence of multiple regulatory factors including androgen and peptide growth factors are suspected to contribute to pro static cell proliferation and pathogenesis. The species-specific nature of BPH and the lack of an appropriate mouse model have impeded progress in the delineation of the causal factors for the development of BPH and testing of potential intervention strategies. It is our hypothesis that prostate-specific overexpression of the androgen receptor (AR) and insulinlike growth factor-1 (IGF- 1) in transgenic mice would cause increased prostatic cell proliferation and would give rise to a pathological condition similar to human BPH. The first specific aim of this proposal is to generate transgenic mice overexpressing AR in the prostate targeted by a ten kilobase pair long homologous mouse probasin gene promoter and to characterize the age-and androgen-dependent changes in the prostatic morphology, cellular composition and gene expression profiles. Region (proximal, intermediate and distal)- and lobe-specific histopathologic changes during aging will be correlated with gene expression profiles determined by micro array analysis. In the

30

Benign Prostatic Hyperplasia

second specific aim, we will elucidate the interacting role of AR and IGF-1 in promoting aberrant cell proliferation and gene expression through comparative analysis of monotransgenic mice with individual prostatic overexpression of AR and IGF- 1 and bitransgenic mice with simultaneous overexpression of both AR and IGF- 1 in the prostate. Our preliminary results support the feasibility of the proposed experiments and successful completion of this study is expected to provide important new insights into the cellular and molecular pathways that lead to the development of the prostatic hyperplasia under the influence of physiological stimuli. Additionally, the transgemc model and molecular markers generated through these investigations will be beneficial for future studies concerning the development of effective intervention strategies and progression/remission of the disease process.

Project Title: ALTERNATE THERAPIES FOR BENIGN PROSTATE SYMPTOMS Principal Investigator & Institution: Dixon, Chistopher M.; Urology; New York University School of Medicine 550 1St Ave New York, Ny 10016 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAR-2009 Summary: (provided by applicant): Over the past 10 years, medical therapy for men with symptomatic benign prostatic hyperplasia (BPH) has become first-line therapy. Well-designed clinical trials have defined the role of medical therapy for symptom reduction, improved quality of life and diminished the likelihood of disease progression. Phytotherapy for BPH has long been a popular therapeutic option in spite of the lack of compelling scientific information about the mechanism(s) of action, magnitude of symptom improvement, adverse effects or long-term preventative role of these extracts. The primary objective of this application is to determine whether the long-term use of saw palmetto or pygeum africanum delays or prevents the progression of clinical BPH as compared to placebo. Clinical progression will be specifically defined as symptom progression, acute urinary retention, recurrent infection or urosepsis, urinary incontinence or renal insufficiency. Patients will also be classified if they crossover to other BPH treatment options (watchful waiting, medical or invasive treatment). The secondary research questions include an assessment of the natural history of BPH in a well-defined population, differences over time between the 3 cohorts with respect to symptom score, quality of life, urinary flow rates, post void urinary residual, sexual function and prostate volume. The subgroup hypotheses will assess whether treatment response is related to symptom severity, urinary flow rate, residual urine, prostate size or prostate specific antigen hopefully providing some insight into the mechanism of action should these agents be proven effective. The study will enroll approximately 3000 men at 10 centers during the first 2 years. Patients will be followed at 3-month intervals for 4 to 6 years using standard outcome measures. This trial will determine whether saw palmetto or pygeum africanum are worthwhile alternative for the treatment of men with symptomatic BPH.

Medicine trials group as a Clinical Evaluation and Treatment Center (CETC) in a multiinstitutional research consortium. The purpose of this consortium is to study the effect of phytotherapy using Sernoa repens (saw palmetto) and Pygeum africanum in men with benign prostatic hyperplasia (BPH). A large segment of the United States population uses phytotherapy for treatment of symptoms of BPH, yet there is little scientific data regarding long-term treatment with these agents. Our proposal here at the CETC will enroll 300 patients in this trial during the enrollment period and follow them for the duration of the trial for a minimum of four years and a maximum of six years. The primary outcome measure will be the clinical progression of BPH. The recruitment, marketing, and retention strategies outlined in the following sections will ensure this level of participation as well as maximize the center's ability to recruit minority populations. This center has all the clinical and laboratory support required as stated in the protocol. The following sections outline innovative methods to recruit a large number of men with BPH as well as multiple strategies to ensure long-term compliance and completion of all scheduled follow-up visits. In summary, this proposal outlines what we believe are the outstanding credentials of the University of Iowa Department of Urology and Preventive Medicine to serve as a Clinical Evaluation and Treatment Center for this multi-institutional clinical trial.

Almost every individual study, systematic review and meta-analysis report analyzing the effect of these phytotherapeutic agents on BPH have come to the same conclusion: further research is needed to determine the long term safety and effectiveness and ability to prevent complications associated with progressive BPH. The primary objective of this study is to determine if serenoa repens or pygeum africanum delays or prevents clinical progression of benign prostatic hyperplasia compared to placebo treatment. Secondary objectives will compare relative efficacy of these two treatments and also determine whether either of these agents ameliorate symptoms of BPH, improve BPH specific quality of life, improve maximum flow rate and reduce residual urine in men with BPH. Men with mild to moderate symptoms of BPH who do not desire or require immediate medical or surgical treatment will be randomized to placebo, serenoa repens or pygeum africanum after placebo run in and will be followed for disease progression for a minimum of four years. Progression will be defined as an increase in AUA symptom score of 4 or more points from baseline, or occurrence of any of the following complications of BPH; acute urinary retention, incontinence, obstructive uropathy (measured as increased creatinine) or BPH related urinary tract infection. The Canadian BPH Research Group (Canadian CETC) have demonstrated experience and expertise in designing and implementing multi-center clinical trials in BPH and are the most successful research group in Canada in recruiting patients to multi-center BPH trials. The principal investigator has been a successful and effective collaborator in studies funded by NIH-NIDDK. The members of this group have demonstrated their

Project Title: ALTERNATIVE THERAPIES FOR BENIGN PROSTATIC SYMPTOMS Principal Investigator & Institution: Naslund, Michael J.; Surgery; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAR-2009 Summary: (provided by applicant): The purpose of this request is to establish a cooperative group of approximately 10 prostate evaluation and treatment centers nationwide which will develop and conduct a prospective, randomized, double-blind, placebo controlled clinical trial to determine whether Saw Palmetto(SP) and/or Pygeum Africanum(AP) can prevent the clinical progression of benign prostatic hyperplasia (BPH). BPH is a common disease in men over 50 which can lead to bothersome voiding symptoms, urinary retention, permanent bladder damage, renal failure, urinary tract infections, urosepsis or urinary incontinence. Treatment options with documented efficacy include medication, several thermotherapy options, and surgical prostatectomy. Phytotherapy is another treatment option for BPH which is used widely in Europe and is experiencing increasing utilization in the United States. Two common phytotherapeutic agents SP and PA. Despite the widespread use of these substances, there is no convincing data in the literature which demonstrates efficacy for the treatment of BPH. These phytotherapeutic substances do appear to be safe from the patients' perspective. The objective of this trial is to determine if SP and/or PA can prevent the clinical progression of BPH, as defined by the development of: acute urinary retention, renal insufficiency due to BPH, recurrent urinary tract infections, urinary incontinence, or an increase in the international prostate symptom score (IPSS) of 4 or more points over a four year trial. Parameters to be assessed in the subjects enrolled in this trial include IPSS, peak urinary flow rate, post void residual volumes, quality of life and sexual health questionnaires, prostate size determined by prostatic ultrasound, blood count and blood chemistries, urinalysis, serum hormone levels, a history and physical examination. Patients will be assessed every 3 months over a four year trial period. The chosen group of collaborators will meet to design the protocol including diagnostic criteria, inclusion/exclusion criteria, safety measurements and quality of life outcome measurements. The trial will commence after the protocol has been developed, an operations manual has been completed and data collection techniques have been established. Each site will obtain IRB approval of the final protocol. When the study is complete and the data has been analyzed, publication of relevent results will be done.

Re-instating functional apoptotic mechanisms, by targeting specific components in this pathway, are of high significance

Studies

in the regulation of prostate growth. Recent studies documented the ability for quinazoline-based a1-adrenoceptor antagonists, doxazosin and terazosin, to induce apoptosis in human prostate smooth muscle, benign and malignant epithelial cells, via an a1-adrenoceptor independent mechanism and suppress tissue vascularity. Our hypothesis is that quinazoline-based a1-adrenoceptor antagonists suppress prostate growth by inducing apoptosis (via induction of intracellular signaling effectors) and inhibit angiogenesis by promoting anoikis (via interference with extracellular matrix attachments). To test this hypothesis, the following aims are proposed: In Specific Aim 1 we will use DNA microarray analysis and proteomic analysis to identify intracellular signaling effectors of apoptosis induced by quinazoline-based a1-adrenoceptor antagonists in prostate benign and malignant cells. Specific Aim 2 will identify the extracellular matrix components involved in quinazoline-induced anoikis in prostate epithelial and endothelial cells with focus on Fas-Fasligand-caspase-8 activation mechanism and integrin effectors. Specific Aim 3 will establish that the quinazolines, doxazosin and terazosin, suppress prostate vasculature and inhibit tissue angiogenesis in patients after a1 blockade treatment. Immunohistochemical analysis will be performed on tissue specimens from BPH patients treated with a1 blockade (for obstructive symptoms) using antibodies against Factor VIII (microcrossed density), vascular endothelial growth factor (VEGF), and focal ashesion kinase (FAK). The goal of the proposed studies is to determine the early response genes at the intracellular (TGFbeta) and extracellular matrix (integrins) environment underlying the quinazolinemediated apoptosis, targeted by this pharmacologic intervention in benign and malignant prostate growth. Potential results will establish the apoptotic/anoikis effect by the quinazolines as a significant phenomenon with clinical relevance in development and progression of benign prostatic hyperplasia (BPH) prostate cancer.

Project Title: ANTI-GM1B IGM FOR DETECTION OF LOCALIZED PROSTATE CANCER Principal Investigator & Institution: Ravindranath, Mepur H.; John Wayne Cancer Institute 2200 Santa Monica Blvd Santa Monica, Ca 90404 Timing: Fiscal Year 2004; Project Start 01-APR-2004; Project End 31-MAR-2006 Summary: (provided by applicant): The discovery that tumor cells escape ceramidemediated apoptosis by glycosylating ceramides and storing them as gangliosides (lactosylceramides with sialic acids) suggests that gangliosides (Ggs) may be valuable targets for diagnostic and therapeutic explorations. Stored Ggs are released into the tumor microenvironment and the circulation, where they suppress a variety of cellmediated immune functions. While studying the tumor Ggs shed into the circulation after cryosurgical ablation of liver tumors, we observed that these shed gangliosides induced production of IgM specific to the tumor Ggs. Assay of sera from patients with early-stage sarcoma, colorectal carcinoma and melanoma confirmed the presence of anti-ganglioside IgMs characteristic of early tumors. These novel and serendipitous discoveries led us to evaluate whether specific anti-Gg lgM antibodies could serve as diagnostic and prognostic markers of subclinical prostate cancer (CAP). CaP progresses imperceptibly and is potentially curable when organ-confined. A noninvasive method for early detection would encourage more men to seek chemopreventive treatments before their CaP has metastasized beyond the prostate. Prostate-specific antigen (PSA) is widely used for diagnosing and monitoring CaP. However, serum PSA level does not increase significantly until tumor volume exceeds 1cc, and it is inversely related to a tumor's histologic grade. Moreover, benign prostatic hyperplasia (BPH) and prostatitis

34

Benign Prostatic Hyperplasia

can falsely elevate serum PSA. By contrast, serum levels of anti-Gg IgM antibodies in healthy individuals decline with age and remain low (titer <50) above the age of 60. In CaP patients above 60 years of age, serum anti-Gg IgM antibodies, particularly antiGD1a, are highly elevated, possibly due to release and sensitization of tumor Ggs. We have observed that serum IgM antibodies from CaP patients immunostained GM1b more strongly than GD1a, suggesting that GM1b may be more immunogenic in patients. We hypothesize that serum anti-GM1b and anti-GD1a IgM in patients with early-stage CaP (T1c) may represent potential markers for localized disease. Although anti-GM1b is not available from commercial sources, we have identified GM1b in large quantities in CaP cell lines. Therefore we will purify GM1b from CaP lines. We hypothesize that the anti-GM1b and anti-GD1a IgM could be more sensitive prognostic markers in patients with localized disease. We will determine their diagnostic potential with and without serum PSA for identifying patients with stage T1 CaP. 1. To isolate and purify CaPassociated ganglioside GMlb from PC3 and Du145 cell lines, and use this ganglioside to study anti-GM1b IgM antibody titers in sera of patients with localized CaP. 2.

Project Title: BIS-PHENOL A: SIGNALING AND MITOGENESIS IN THE PROSTATE Principal Investigator & Institution: Knudsen, Karen E.; Cell Biol, Neurobiol/Anatomy; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant): Environmental and commercially prevalent estrogenic compounds (xenoestrogens) have been classified as endocrine disruptors, or agents capable of disrupting normal hormone function in the human body. Exposure to xenoestrogens has been shown to result in diverse biological outcomes, such as infertility and developmental defects. Although considerable effort has been directed toward delineating the effect of xenoestrogens on the female reproductive system, few studies have examined the effect of such agents on growth and maintenance of the prostate gland. Prostatic epithelia and the cells of primary prostatic adenocarcinomas are dependent on androgen for proliferation and survival. This critical dependence of the prostate on androgen is exploited in the treatment of prostatic proliferative diseases (e.g. benign prostatic hyperplasia and prostatic adenocarcinoma). Increasing evidence also demonstrates a role for estrogen in the prostate cell proliferation. For example, exposure to estrogen has been shown to directly induce prostate hyperplasia animal model systems. Additionally, the anti-estrogen Tamoxifen is used clinically to reduce prostate growth. Despite these observations, the mechanism by which estrogen stimulates prostate cell growth has not been determined. Moreover, the effect of xenoestrogens on prostate proliferation and growth has not been explored. Here we show that the xenoestrogen bis-phenol A (BPA) provides inappropriate mitogenic stimuli to prostatic epithelial cells. This mitogenic activity is associated with nuclear receptor activity, and allows prostate cells to bypass their requirement for androgen. Based on our preliminary data, we hypothesize that BPA activates specific nuclear receptors in prostate cells to propagate inappropriate mitogenic signaling pathways and initiate cellular proliferation. This action of BPA likely facilitates the development of prostate hyperplasias and neoplasias. The experiments outlined herein will determine

the mechanism by which BPA activates nuclear receptors in prostate epithelia, define the mitogenic signaling pathway for BPA in this cell type, and assess the influence of these agents on the formation and treatment of prostate hyperplasias and neoplasias.

Project Title: BLADDER OUTLET OBSTRUCTION INDUCED NEUROPLASTICITY Principal Investigator & Institution: Zvara, Peter; Surgery; University of Vermont & St Agric College 340 Waterman Building Burlington, Vt 05405 Timing: Fiscal Year 2002; Project Start 15-AUG-2001; Project End 31-JUL-2004 Summary: (provided by applicant) Benign prostatic hyperplasia (BPH) is the most common cause of bladder outflow obstruction (BOO). This condition is commonly associated with uninhibited urinary bladder contractions. Irritative voiding symptoms, a consequence of uninhibited bladder contractions are very bothersome to a large population of aging men, adversely affecting their quality of life. The overall hypothesis for this research proposal is that the marked changes in the neural control of voiding function that occur following BPH are mediated by multiple factors, including: (1) changes in the properties of urinary bladder afferent neurons induced by peripheral organ (bladder) dysfunction and (2) changes in the properties of interneuronal populations in the spinal cord. Thus, we propose that reorganization of spinal micturition circuitry occurs in response to changes in neural-target organ interactions. We plan to examine the effects of BOO on the neurochemical, organizational and morphological properties of afferent and spinal neurons involved in the micturition reflex pathway. This research proposal aims to provide a more thorough understanding of the wiring diagram for lower urinary tract reflexes and the functions of neurotransmitters in these reflexes. In the first part of our study we will assess neurochemical changes in neurons involved in the micturition reflex that project to the periphery following BOO. Peripheral and spinal neurons projecting to the bladder will be identified following injection of the tracer into the urinary bladder. Subsequently, immunohistochemical techniques will be used to determine changes in the expression of neuroactive compounds in these neurons. A second group of experiments will use pharmacological techniques to evaluate the role of neuroactive compounds in the central micturition pathway following chronic BOO. The effect of selective inhibitors of these neuroactive compounds on the micturition reflexes following BOO and in shamoperated controls will be determined with the use of the cystometrography (recording pressure changes in the urinary bladder during filling and micturition). In the third part of this research project, we propose to determine the organization of urinary bladder interneurons and parasympathetic preganglionic neurons in the. lumbosacral spinal cord. Changes in connectivity between the various spinal elements will be assessed following BOO. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

The identification of MeHPLA as a ligand for type II sites which controls cell growth led to

36

Benign Prostatic Hyperplasia

the development of MeHPLA-related compounds with antiproliferative activities and potential for the treatment of benign prostatic hyperplasia, endometriosis, breast and prostatic cancer. We recently identified the nuclear type II binding site as histone H4. This exciting discovery targets very specific genomic pathways for regulation by MeHPLA and related-compounds including bioflavonoids and phytoestrogens. These compounds bind to type II sites (histone H4) with high affinity and have classically been defined as antioxidants that scavage free radicals. Our recent data indicate very specific regulation of gene transcription at the level of chromatin structure and function by type II site (histone H4) ligands. Histone acetylation is temporally and functionally coupled to DNA replication and gene expression in experimental systems including uterus and cancer cells. We propose that MeHPLA and related compounds control normal and malignant cell proliferation by modulating chromatin acetylation patterns and core nucleosome unwinding by binding to histone H4. We will assess hormonal (estrogen, progesterone) modulation of histone H4 gene expression (mRNA and protein), ligand binding activity and cell proliferation in rat uterus and in ER-dependent (MCF-7 cells) and ER-independent (MDA-MD-231) breast cancer cells in vitro and when grown in nude mice (Specific Aim 1). Potential involvement of histones H1, H2A, H2B and H3 in ligand binding to histone H4 will be studied (Specific Aim 2). The identity of the ligand binding domain(s) on histone H4 by will be determined by protein sequencing and site directed mutagenesis studies (Specific Aim 3). Effects of MeHPLA and related histone H4 ligands on chromatin structure, histone acetylation, and steroid hormone-dependent chromatin remodeling and gene transcription in a cell free system (Specific Aim 4) will be assessed. Estrogen, antiestrogen and MeHPLArelated compound effect on the acetylation of histone H4 (or other histones), specific gene (cyclin Dl and p21) transcription and expression and cell proliferation (cell cycle transcition, etc.) in estrogen-dependent and estrogen-independent breast cancer cells in vitro and in vivo (Specific Aim 5) will be evaluated. The proposed studies should precisely define specific effects of MeHPLA and bioflavonoids on chromatin structure and function, growth related gene transcription and cellular proliferation in normal and malignant cells.

Project Title: CLINICAL EVALUATION & TREATMENT CENTER FOR BPH Principal Investigator & Institution: Andriole, Gerald L.; Surgery; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAR-2009 Summary: (provided by applicant): Lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) are one of the most common disorders of the aging U.S. male. Over the last decade significant advances have been made in characterizing this abnormality and treating it with medical therapy (such as alpha blockers and 5 alpha reductase inhibitors) and minimally invasive surgical techniques (such as stents, lasers, hyperthermia and others). Despite this, use of non-traditional medical therapies for LUTS has greatly increased in recent years. Most trials evaluating these agents are limited by small size, short study interval and absence of standardized testing instruments. For these reasons there is a need to evaluate non-traditional agents such as saw palmetto and pygeum Africanum in a large scale, randomized, placebo-controlled, long-term trial. In this application, we propose one such study, describe our clinical research environment, including patient population, facilities, personnel, experience with prior studies, and other methods to assure recruitment, protocol compliance, and retention for such a study. We describe our willingness to develop a final protocol and collaborate in performing it.

Principal Investigator & Institution: Kristal, Alan R.; Member and Associate Head; Fred Hutchinson Cancer Research Center Box 19024, 1100 Fairview Ave N Seattle, Wa 98109 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2006 Summary: (provided by applicant): The overall goal of this application is to understand relationships among hormonal, genetic and behavioral risk factors for symptomatic benign prostatic hyperplasia (BPH). BPH symptoms affect well over half of American men over age 50, with substantial effects on quality of life and medical care cost of over 4 billion dollars annually. This study will assess whether the risk of symptomatic BPH is associated with (1) serum concentrations of steroid hormones and insulin-like growth factors known to affect prostate growth; (2) polymorphisms in genes that affect hormone and growth factor metabolism or activity; and (3) diet and other lifestyle factors that affect steroid hormones and insulin-like growth factor concentration or activity. Data are from the Prostate Cancer Prevention Trial (PCPT), a double blinded, placebo-controlled, randomized trial of the drug finasteride (Proscar) for the primary prevention of prostate cancer. Analyses will be restricted to the approximate 5,000 men in the placebo control group with no medical history or symptoms of BPH at baseline. The primary endpoint, incidence of symptomatic BPH, is based on careful and standardized assessments of lower urinary tract symptoms and treatment for prostate-related disease collected at baseline and annually for 7 years. Steroid hormones, insulin-like growth factor 1 and insulin-like growth factor binding protein 3 will be measured from plasma banked at baseline, and genetic characteristics will be assessed using banked lymphocytes. Diet and other behavioral risk factors were assessed by both interviewer- and selfadministered questionnaires. A nested case-control design, with 700 cases and 700 controls, will be used to address hypotheses related to serum measures and genetic polymorphisms. A cohort study using all 5,000 men will be used to examine hypotheses related to diet and other behavioral risk factors. The nested case-control studies are powered to detect odds ratios of 1.5 and the cohort studies are powered to detect hazard ratios of 1.35, comparing highest to lowest quartiles of exposures, with type I error = 0.05 and type II error = 0.20. This study is highly cost-effective, as all data and samples have been collected, and funds are requested for laboratory analyses of serum and genetic polymorphisms, data preparation, statistical analyses and manuscript preparation. Results from this study will enhance our understanding of the etiology of symptomatic BPH and could potentially be used to develop new strategies for prevention and control of this very common disease.

Project Title: CONTROL OF PROSTATE-SPECIFIC GENE EXPRESSION Principal Investigator & Institution: Matusik, Robert J.; Director of Urologic Research; Surgery; Vanderbilt University 3319 West End Ave. Nashville, Tn 372036917 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-MAY-2003 Summary: With the approach of adulthood, the prostate undergoes a developmental change that results in the maturation of that gland at puberty. At this stage, the prostate becomes a differentiated gland which produces proteins fundamental for reproduction and survival of the species. Two recent population trends place the understanding of these processes at the forefront. A decline in male fertility requires a better understanding of normal, reproductive development and an increasing aging population demands a better understanding of the further stages of prostatic growth that often leads to benign prostatic hyperplasia and/or prostate cancer. Androgen plays a key role in the normal development of the prostate however, little is known about the other basic molecular events that are required for organ determination and cell differentiation of the prostate. We have shown that an extremely small probasin promoter fragment contains the necessary regulatory information to target both developmental and prostatic epithelial-specific gene expression to the prostate of transgenic mice. Our hypothesis is that these PB DNA sequences can be used to identify the critical gene regulatory proteins that govern prostatic epithelial cell-specific gene expression. We believe that identifying these critical regulatory proteins which control prostate-specific gene expression will elucidate the mechanisms that control both cell determination and cell differentiation of the prostate. To decipher the information within this PB DNA fragment, the following specific Aims are planned: 1) to characterize the ontogeny of prostate-specific probasin gene expression in the developing mouse UGS; 2) to identify the PB promoter sequences that dictate prostatespecific gene expression; 3) to clone the regulatory factors that interact with the prostatespecific sequences; and 4) to determine the patterns of expression of these prostatespecific factors in the developing mouse. The ultimate goal is to provide a basic understanding of prostatic epithelial cell gene expression that will lead to insight in male infertility and the mechanism that lead to prostatic disease.

Project Title: CYCLIN DEPENDENT KINASE INHIBITORS IN BENIGN AND MALIGNANT PROSTATIC DISEASES Principal Investigator & Institution: Cordon-Cardo, Carlos; Director; Sloan-Kettering Institute for Cancer Res New York, Ny 100216007 Timing: Fiscal Year 2002 Summary: The objective of our research focuses on the continued characterization of mutations and altered expression patterns of cyclin-dependent kinase inhibitors (CKI) as they rate to processes of tumorigenesis and tumor progression in prostate cancer. It is our hypothesis that abnormalities of KIP and INK genes, as well as those that affect their encoded products, produce a selective advantage for prostate growth and an aggressive behavior in prostate cancer patients. The Specific Aims are outlined as follows: Aim #1: To determine the frequency and potential clinical relevance of mutations affecting the KIP genes, as well as altered patterns of expression of their encoded proteins, in benign prostatic hyperplasia (BPH) and prostate carcinoma. We have found distinct p27 anomalies in BPH and prostate tumors, supporting the postulate that BPH is not a premalignant lesion. Moreover, prostatic carcinomas displaying a p27 negative phenotype were found to be biologically more aggressive. We plan to validate these

observations and to study p21 and p57 genes. Aim #2: To define the rate and possible clinical relevance of mutations arising in the INK genes, as well as altered patterns of expression of their encoded products, in BPH and prostatic carcinoma. Preliminary data reveals that altered patterns of p16 expression and methylation of he p16 promoter are frequent events in prostate cancer. We plan to extend and validate these data and to assess the relevance of alterations affecting p18 and p19. Aim #3: To further characterize the histopathology of prostatic tissue in animal models for loss of KIP or INK function, and to produce transgenic models using tissue-specific promoters. We have engineered CKI knockout mice (ie, p27 and Ink4a). p27 mull mice develop hyper-cellular prostatic glands; however,over prostate neoplasms are not observed. Transgenic mice will be generated using cyclins E or each D-type fused to the rat probasin promoter in the presence and absence of either p27 or p16. A model mimicking the human disease is expected. The goal is to translated basic and clinical research findings into clinical studies, and to collaborate with the O'Brien Centers and members of the scientific community, evaluating tumor markers of potential relevance.

Project Title: DATA COORDINATING CENTER FOR BENIGN PROSTATE SYMPTOMS Principal Investigator & Institution: Lee, Jeannette Y.; Research Professor; Medicine; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAR-2009 Summary: (provided by applicant): This proposal is for the Medical Statistics Section (MSS) at the University of Alabama at Birmingham to serve as the Data Coordinating Center (DCC) for the study of alternative therapies in benign prostate symptoms. It is anticipated that 10 Clinical Evaluation and Treatment Centers (CETCs) will enroll approximately 3100 men with benign prostatic hyperplasia (BPH) in a randomized, double-masked, placebo-controlled study of two phytotherapy agents, Serenoa repens (Saw palmetto) and Pygeum africanum in the treatment of BPH. Specific aims of the DCC are to: provide statistical expertise in study design and analyses; provide data management support for the study; develop and maintain a WEB-based system for data transmission and communication from the CETCs to the DCC; establish a Phytotherapy Distribution Center to distribute Saw palmetto, Pygeum africanum and placebo to the CETCs; and provide administrative support for meetings of the Steering and Planning Committee, Executive Committee, Data Safety and Monitoring Board and any subcommittees formed during the progress of the trial. The strengths of the MSS in serving as the DCC are: its well-established infrastructure (personnel, computing facilities, communications networks, and data management system) for providing support to clinical trials; its experience in serving as the coordinating center for NIHsupported multicenter clinical trials groups; and its participation in the UAB Chemoprevention Center.

medical problems associated with benign prostatic hyperplasia. The overall goal of the study is to test the effectiveness of pharmacological intervention in benign prostatic hyperplasia (BPH) with the hope that pharmacological intervention may prove to be superior to surgery for some patients. The goal of the project under consideration from the University of Colorado is to establish the requested Diagnostic Center for the fullscale trial. The Diagnostic Center will perform assays on peripheral blood with materials sent from several clinical centers; these assays will include prostate specific antigen, luteinizing hormone, testosterone, and dihydrotestosterone. Blood chemistries will be carried out initially and annually for the duration of the trial (described in Appendix F of the protocol). The Diagnostic Center will receive four fixed and two frozen, 18-gauge needle biopsies from each patient entered into the study. A series of slides made from the paraffin-embedded fixed needle biopsies and from the frozen needle biopsies will be examined. These slides will be examined for diagnostic purposes by the principal investigator and an unidentified fellow who will be appointed in the second year of support. Sets of slides will also be made available to the departments of pathology from the hospitals from which the biopsies are obtained. The pathology analyzed in the Diagnostic Center in Denver will be recorded on a standard form that is displayed in the material sent with the application. Additional sections of paraffin-embedded needle biopsies and the remaining materials from frozen needle biopsies will be stored for research in the future. Biopsies will be carried out at the beginning of the study, after one year, and at the end of the study. In addition to the above, immunohistochemical studies will be carried out to assess the expression of prostate specific antigen and the MIB-1 nuclear proliferation antigen. Apoptosis will be evaluated with the TUNEL immunohistochemical technique. Morphometric evaluations will be carried out "using a semiautomated image analysis approach such as that described by Shapiro et al (44)." The step by step methods of staining are listed. The investigators state that conditions stipulated in the pilot study that was carried out in their center made in "impossible.to have any information about the expected ranges of variation for each of the variables with respect to any measures of treatment outcome.From the published literature, however, it is expected that data on 280 patients will be sufficient to produce meaningful results." They state that a ".subset of approximately 280 cases will have detailed analyses performed." Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: EFFECTS OF AGING ON PROSTATE STRUCTURE AND FUNCTION Principal Investigator & Institution: Brown, Terry R.; Professor; None; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 01-MAY-2003; Project End 31-MAR-2008 Summary: (provided by applicant): Aging is a major factor that contributes to abnormal growth of the prostate leading to the condition of benign prostatic hyperplasia (BPH) in men. Unlike the human prostate, the rodent prostate is organized into different anatomical lobes referred to as the ventral, dorsal and lateral. Each lobe is biochemically distinct and differentially responsive to androgens. Based upon embryologic origin and biochemical function, the lateral and dorsal lobes have been considered homologous to the human prostate, whereas the ventral lobe lacks homology. Past studies in our laboratory have established that spontaneous and androgen-stimulated prostate epithelial cell hyperplasia occurs in the dorsal and lateral, but not the ventral lobe of aging Brown Norway rats. Hence, the age-dependent, lobe-specific prostatic hyperplasia of Brown Norway rats is considered to be a model for human BPH. Our working hypothesis is that aging contributes to a progressive increase in oxidative stress within

the prostate, the consequences of which are alterations in the lobe-specific sensitivity to androgen and alterations in cell regulatory mechanisms. These alterations manifest themselves in the form or reactivated cell proliferation and increased cell survival, with the net effect being cellular hyperplasia. The lobe-specific, age-dependent occurrence of hyperplasia provides a unique model to understand the factors that differentially contribute to hyperplasia. In this application, we propose three aims to determine: 1) if changes in androgen sensitivity alter the expression of cell cycle regulatory molecules that activate cell proliferation leading to hyperplasia; 2) if changes in growth factor regulation and expression increase cell proliferation and survival leading to hyperplasia; and 3) if oxidative stress causes damage to lipids, proteins and DNA that correlates with disruption of normal regulation of prostate growth. These studies should lead to a better understanding of the molecular mechanisms that underlie the incidence of prostatic hyperplasia with increasing age, particularly at a time in life when the androgendependent prostate is exposed to a hormonal milieu with paradoxically diminished testosterone concentration.

Project Title: EFFECTS OF SAW PALMETTO EXTRACT ON SYMPTOMATIC BENIGN PROSTATIC HYPERPLASIA Principal Investigator & Institution: Hess, David L.; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2002 Summary: Saw palmetto extract (SPE) has seen wide use in Europe for self treatment of benign prostatic hyperplasia (BPH), although the mechanism of action on the human prostate is unknown and efficacy of treatment remains unproven. Suggested mechanisms include inhibition of androgen action and an anti-inflammatory effect. These possibilities were evaluated by study of prostate biopsy specimens obtained before and after treatment with SPE in men during a 6 month randomized clinical trial vs a placebo. Ultrasound-guided sextant biopsies were obtained from 41 men prior to and after 6 months of placebo (n=20) or SPE (n=20) treatment (320 mg/day). The 82 tissue samples were batch processed by routine histology; by morphometry for quantitative tissue composition of the inner and outer gland; by a histopathologic scoring system for acute and chronic inflammation and for atrophy; by immunohistochemical assessment of apoptosis, cell proliferation, and androgen receptor expression; an d by a tissue homogenate assay for androgen levels (expressed as ng/g of prostate tissue). A contraction in the transition zone epithelium from 17.8% before to 10.7% after 6 months of treatment was found in the SPE group (p < 0.01). In a parallel, independent analysis, the epithelial atrophy scores increased from 25.2% before to 40.9% after SPE (p < 0.01). In placebo patients, no significant changes were seen in any tissue measures. None of the other tissue studies revealed any significant changes from baseline during SPE treatment. SPE appears to exert a suppressant effect on the prostatic epithelium, especially the transition zone. Since no alterations in prostatic androgen metabolism or apoptosis markers could be demonstrated, the data suggest that the effect is mediated by a mechanism unrelated to changes in tissue hormone concentrations, receptor expression or to obvious anti-inflammatory effects. How epithelial suppression related to clinical effects, in the absence of pro state volume contraction, is not clear. However, our observation of significant epithelial involution following 6 months of SPE use should encourage further investigation.

Project Title: EPIDEMIOLOGY OF UROLOGIC DISORDERS IN MINORITY MEN Principal Investigator & Institution: Mckinlay, John B.; Senior Vice President and Director; New England Research Institutes, Inc. 9 Galen St Watertown, Ma 02472 Timing: Fiscal Year 2002; Project Start 15-JUN-2001; Project End 30-APR-2006 Summary: Urologic disorders, including erectile dysfunction, benign prostatic hyperplasia, prostatis, and hypogonadism, are highly prevalent and have enormous impact on the health, medical-care expenditures, and quality of life of the aging U.S. male population. Surprisingly little is known about the basic epidemiology of these conditions, particularly in minority populations, where they may be especially prevalent. Several professional societies and the NIH have urged that research on urologic disorders in minority men be given highest priority. Similar recommendations regarding erectile dysfunction were made by a 1993 NIH Consensus Conference. The role of health-care access and utilization in relation to the specific conditions is likewise studied. We purpose to conduct a cross-sectional, population-based random- sample survey, building on the field experience of investigators from the Massachusetts Male Aging Study, to examine the epidemiology of urologic disorders in minority men. We will estimate and compare the age-specific prevalence of urologic conditions in Hispanic, black (non- Hispanic), and white (non-Hispanic) men. We will measure the relative contribution of biophysiologic factors, health status, medications and comorbidities, lifestyle and behavioral within each minority group and to variation among the three groups. Medical care access, utilization behavior, and quality of life dimensions will also be explored. Our random sample will include a total of 3000 men aged 40-79 year, 1000 from each of the three above mentioned racial/ethnic groups living in the Boston, MA metropolitan area. We will collect blood samples and comprehensive battery of health information in an in-home interview conducted by bilingual interviewer-phlebotomists. To prepare for the possibility of a future, separately funded prospective study we will actively maintain the sample through regular main contact. This design represents a cost-efficient approach to gathering detailed information on four poorly understood medical conditions in a single wave of field effort.

Principal Investigator & Institution: Saxena, Indu; Senior Scientist and Group Leader; Intelligent Optical Systems, Inc. 2520 W 237Th St Torrance, Ca 905055217 Timing: Fiscal Year 2002; Project Start 01-APR-1998; Project End 31-AUG-2004 Summary: (provided by applicant): To improve hyperthermia and thermotherapy treatments by providing a realistic, cost effective and efficient technique for temperature profiling in treated tissues, Intelligent Optical Systems proposes to develop an optical fiber temperature (OFT) probe providing 10 points of high resolution temperature data in a single fiber. The OFT probe is an efficient alternative to thick bundles of arrayed single point temperature probes and expensive MRI thermometry to provide distributed temperature monitoring in tissue. In addition to BPH treatments, all intracavital treatments will benefit from the OFTs in-situ temperature profiling. Due to its nonconducting nature, the optical fiber probe is especially suited to radio frequency and microwave hyperthermia applications. In Phase I, the OFT probe demonstrated temperature measurement every 0.5 cm along the optical fiber with an accuracy of 0.2 degrees C, while reading all 7 points simultaneously in less than 5 seconds. These

features of our OFT probe have already received keen interest from potential commercial partners. lOS proposes to develop a complete, clinically validated sensor probe with optoelectronic instrumentation as the Phase II end product. PROPOSED COMMERCIAL APPLICATION: As microwave hyperthermia becomes increasingly popular for treatment of benign tumors such as benign prostatic hyperplasia and other benign or malignant tumors, IOS's optical fiber temperature probe will be an integral part of the instrumentation required for effective treatment, providing multipoint, selfcalibrating temperature sensing with high accuracy. Other non-invasive, multipoint thermometric medical applications that are accessible via narrow pathways will benefit from development of this device.

Project Title: FORMS OF PROSTATE SPECIFIC ANTIGEN AND HK2 IN CANCER Principal Investigator & Institution: Heeb, Mary J.; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 01-MAY-1993; Project End 31-JAN-2004 Summary: We seek to extend promising studies showing that prostate specific antigen (PSA) and glandular kallikrein (hK2) occur in several forms in blood of prostate cancer (CaP) patients and that measurement of the proportion of PSA in the form of PSAalpha2-macroglobulin (alpha2M) improves the discrimination between early CaP and benign prostatic hyperplasia (BPH). This will be confirmed with well-characterized prospective patient samples. Moreover, we will measure the proportion of PSA in its various forms in these patients, and identify and measure forms of the related novel CaP marker, hK2. We found that hK2 exists in several forms in CaP plasmas, including hK2alpha2M. Clinical assays do not detect PSA-alpha2M and there are no clinical assays for hK2. We will determine which combination of measurements provides the greatest discrimination between CaP and BPH. Since forms of PSA also vary in early vs. advanced CaP, our assays may also be useful in prognosis. The goal is to provide simple ELISA assays that will reduce the invasive, expensive procedures that are needed for diagnosis and ELISAs that are prognostic, to help physicians choose how aggressively to treat CaP patients, or to identify BPH patients who will develop CaP later. It is hypothesized that PSA and hK2 are secreted as zymogens, activated when needed, and then inactivated by protease inhibitors. The pathophysiology of cells that synthesize PSA and hK2 vary in CaP vs. BPH and possibly in different courses of CaP. The time between PSA or hK2 secretion and translocation to the blood may differ, and the enzymes and inhibitors to which they are exposed in the prostate differs from that in blood. Thus, a different spectrum of PSA and hK2 forms will be found in CaP compared to BPH, and in different courses of CaP. To meet our goals, we will: 1. Identify forms of hK2 in CaP and BPH plasmas and develop assays for relevant hK2 forms. Purify hK2 and prepare antibodies and standard hK2-inhibitor complexes for relevant hK2 forms. 2. Prospectively collect serial blood samples from 300 CaP patients and document full histories. Collect prospective samples from 300 undiagnosed patients with elevated PSA. 3. Measure PSA-alpha2M PSA-ACT, free PSA and "total" PSA in each sample and calculate the proportions of each PSA form. Similarly measure relevant hK2 forms. 4. Correlate the proportions of various forms of PSA and hK2 to the course of disease in all CaP patients to determine the prognostic value of each measurement. 5. Correlate the proportions of various forms of PSA and hK2 to the subsequent diagnosis of CaP or BPH in the patients who were undiagnosed. Determine the specificity and sensitivity of each measurement to determine its diagnostic value. Techniques will include protein

Project Title: FT-IR/GC-MS MODELS FOR PREDICTING PROSTATE CANCER Principal Investigator & Institution: Malins, Donald C.; Pacific Northwest Research Institute 720 Broadway Seattle, Wa 98122 Timing: Fiscal Year 2002; Project Start 15-JAN-1999; Project End 31-DEC-2003 Summary: We have shown that Fourier-transform-infrared (FT-IR) spectroscopy, coupled with advanced statistics, is a powerful means for discriminating between the DNA of normal, pre-malignant and cancer tissues, thus making it possible to establish cancer probability relationships. Previously, we showed that comparable cancer probability relationships could be established using mutagenic and other modified base structures evinced by gas chromatography-mass spectrometry (GC-MS). The overall objective of the proposed work is to further explore the capability of these models for understanding the etiology of prostate cancer and predicting its occurrence at early stages of oncogenesis. The specific aims are (I) to validate, in a blinded study, our published cancer probability models of DNA based on FT-IR/statistics technology for distinguishing between prostate cancer (adenocarcinoma), benign prostatic hyperplasia (BPH) and morphologically normal prostate tissue, using an increased number of cases adjusted for age. This would be expected to confirm our published cancer probability models that were based on a relatively small number of samples; (II) to obtain representative samples from the peripheral, central and transition zones of normal and cancerous prostate glands (from which 70 percent, 20 percent and 10 percent of cancers arise) and determine differences in the DNA structures from each zone, using the FTIR/statistics technology; (III) to determine, with GC-MS, radical- induced base modifications in DNA (e.g., 8-hydroxyguanine) using representative samples from (II) and correlate the results with those obtained by FT-IR/statistics technology; (IV) to determine differences between the DNA of primary prostatic adenocarcinoma and primary tumors that have metastasized based on FT-IR/statistics and GC-MS models; and (V) to apply recently developed equipment for reducing the amount of prostate DNA required for FT-IR spectral analysis to substantially less than a 1.0mug and demonstrate that it produces IR spectra that are statistically indistinguishable from spectra presently obtained with much larger sample sizes. At the conclusion of these studies we expect to have significantly increased understanding of the etiology of prostate cancer and established a promising basis for cancer prediction.

Project Title: GENETIC POLYMORPHISMS BENIGN PROSTATIC HYPERPLASIA Principal Investigator & Institution: Roberts, Rosebud O.; Associate Professor; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 16-MAR-2002; Project End 31-JAN-2005 Summary: (provided by applicant) Benign prostatic hyperplasia (BPH) is the most frequent cause of lower urinary tract symptoms and office visits to urologists among elderly men. Despite this, little is known about the etiology and risk factors for BPH and the only proven risk factors for BPH to date are increasing age and an intact androgen metabolism. Estrogens have also been observed to act synergistically with androgens in the development of BPH. Recent studies suggest that the pathogenesis of BPH is related to a decrease in the serum androgen: estrogen ratio with increasing age. Serum hormone

45

levels, however, have not been consistently associated with BPH risk, possibly because serum levels may not reflect intracellular hormone levels in prostate cells. Since hormone levels within prostate cells may reflect genetic variations, polymorphisms in genes that regulate intracellular androgen and estrogen levels in prostate cells may play an etiologic role in BPH. Several functionally significant polymorphisms have been described for genes that determine androgen and estrogen levels. These polymorphisms may alter the risk of BPH by altering hormone levels or by their effects on androgen and estrogen receptor-mediated events within the prostate. We propose to test the hypothesis that genetic polymorphisms in sex hormone receptors and sex hormone metabolizing enzymes are etiologic risk factors for BPH. In Specific Aim 1 we will test the association between genetic polymorphisms in androgen and estrogen receptor genes and measures of BPH obtained longitudinally in a cohort of men randomly selected from the community. In Specific Aim 2 we will test the association between polymorphisms in genes that encode enzymes involved in androgen and estrogen biosynthesis and activation and measures of BPH in the same cohort. We will evaluate the CYP11A1, CYP17, CYP19, 3Beta hydroxysteroid dehydrogenase, 17BETA hydroxysteroid dehydrogenase types 2,3, 5, and SRD5A2 genes. In SpecificAim 3 we will test the association between polymorphisms in genes that encode enzymes involved in estrogen bioactivation and inactivation and measures of BPH in the same cohort. These genes include CYP1A1, CYP1A2, CYP1B1, catechol 0-methyl transferase, sulfotransferase 1A1, and glutathione S-transferases (M1, P1, and T1). This communitybased cohort study should provide insights that should improve our understanding of the genetic control of hormonal mechanisms in the pathogenesis of BPH.

Project Title: GROWTH FACTORS IN PROSTATE CANCER Principal Investigator & Institution: Mc Keehan, Wallace L.; Professor & Center Director; None; Texas A&M University Health Science Ctr College Station, Tx 778433578 Timing: Fiscal Year 2002; Project Start 01-NOV-1993; Project End 30-APR-2003 Summary: Prostate cancer is the most commonly diagnosed malignancy in men, and ranks second in mortality rate after lung cancer in the USA. Cancer and benign prostatic hyperplasia (BPH) is an increasing socio-economic burden on the medical care system with increase in life span of males. Prostate cancer is progressive to malignancy, but occurs primarily in two stages. Type I cancers are largely responsive to anti-androgen treatment, but over long periods progress to the type II malignant and untreatable state. Understanding of the progressive transition from type I to type II states is urgently needed to guide diagnosis, prevention and treatment. The hypothesis underlying this continuation project is that the progression from the non-malignant to malignant states is a stepwise disruption of homeostasis mediated by communication between epithelium and stroma of the prostate. The heparin-binding fibroblast growth factor (FGF) family of polypeptides and its receptor (FGF-R) has been firmly implicated in mediation of growth and differentiation within the prostate. The FGF family is an extremely heterogenous three component system-FGF polypeptides, FGF receptor kinase and FGF heparan sulfate proteoglycan. This project will determine the molecular and cellular mechanisms underlying mediation of homeostasis (growth, growth inhibition/death and differentiation) by specific members of the FGF family in prostate and the changes that occur during progression to malignancy. Specifically, the project will determine (1) the specific roles of stromal derived FGF-7 and FGF-10 in instruction of epithelial phenotypes; (2) the time course and sequence of changes in the FGF signaling system during progression of pre-malignant tumor epithelial cells to

46

Benign Prostatic Hyperplasia

malignancy; (3) relative roles of the ecto- and intracellular domains of FGFR1 and FGFR2 in the process; (4) role of androgen and its receptor in squamous versus glandular differentiation; (5) structural motifs in FGFR1 and FGFR2 underlying effects on non-malignant and malignant cell phenotypes; (6) impact of changes in specific pericellular heparan sulfates; (7) conditions that regulate alternate splicing of the FGFR2 gene. Lastly, the project will employ mouse genetics to test the physiological consequence of FGFR1 and FGFR2 on prostate tumor progression. These results will open up new avenues for early diagnosis of prostate tumor potential for progression, for prevention of progression and for treatment of malignancies targeted to the FGFR signaling system.

Project Title: HEPARIN-BINDING EGF-LIKE FACTORS IN PROSTATE GROWTH Principal Investigator & Institution: Freeman, Michael R.; Director; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2002; Project Start 01-AUG-1994; Project End 30-NOV-2004 Summary: The human prostate is particularly susceptible to dysfunction arising grow cell growth abnormalities. Prostate adenocarcinoma is now the most commonly diagnosed cancer among American men, accounting for about 40,000 deaths per year at current rates Benign prostatic hyperplasia (BPH), a non-malignant neoplastic disorder of the human prostate that inhibits urine flow through the prostatic urethra, affects over 800,000 men per year in the US. A majority of men over the age of 50 will occasionally or persistently suffer from symptoms attributable to BPH, including urinary retention, urinary tract injection, hematuria, and bladder muscle dysfunction. Although abnormal tissue expansion is evident in both epithelial and stromal compartments in PH, symptoms are thought to arise primarily from expansion of the stromal compartment and from other neuromuscular abnormalities. This is a competing renewal of a proposal to study the role of heparin-binding epidermal growth factor-like growth factor (MBEGF), and related EGF-like factors, in prostate growth. In the first grant period (7/94 through 3/99) we have accumulated significant evidence that HB-EGF is an important growth factor in the adult human prostate, and therefore of potential physiologic relevance to both benign and malignant prostatic disease. Importantly, we found that (1) HB-EGF is synthesized almost exclusively by smooth muscle cells (SMC) of the interstitital stroma and the vascular bed; and (2) that the membrane form of HB-EGF ("mHB-EGF", for "membrane HB-EGF") was most likely the predominant form of the growth factor present in the prostate under steady-state conditions. In the new proposal we will focus on understanding the role of mHB-EGF as a mediator of cell survival and determine whether mHB-EGF or soluble HB-EGF is a physiologic regulator of human prostate smooth muscle cells. The specific aims of the new proposal are: Specific Aim 1: Determine whether unique binding partners of membrane HB-EGF mediate apoptosis and survival signals. We will test the hypothesis that mHB-EGF acts a survival factor independently of the secreted form of the growth factor and that one or more membrane binding partners, including the tetraspan, protein CD9 and the Bcl-2 binding protein, BAG-1, collaborate with mHB-EGF in this survival activity. Specific Aim 2: Determine the mechanism of HB-EGF growth and survival regulation of prostate SMC. In these experiments we will determine whether mHB-EGF or sHB-EGF is the predominant growth/survival regulator in this cell type and identify and determine the role of possible collaborating proteins.

Project Title: HIGH INTENSITY ULTRASOUND FOR PROSTATE TREATMENT Principal Investigator & Institution: Sanghvi, Narendra T.; President; Interscience Research, Inc. Indianapolis, in 46226 Timing: Fiscal Year 2002; Project Start 11-AUG-1998; Project End 30-APR-2004 Description (provided by applicant): High-Intensity Focused Ultrasound (HIFU) phased arrays allow flexibility in beam steering, beam shaping, and dynamic focusing. These features enable them to create large and contiguous tissue lesions of predetermined shape with high efficiency, resulting in shorter treatments, increased accuracy, and ease of operation. The goal of this proposal is to replace the current Sonablate HIFU transducers (mechanically scanned, dual-element, HIFU and imaging capability) used in the clinic for the treatment of BPH and localized prostate cancer with a 2-D HIFU phased array. The array will eliminate "probe switching" during treatment, reduce the reliance on mechanical scanning, and increase treatment effectiveness through dynamic focusing and focal zone shaping. During Phase I, phased array configurations were simulated to determine an optimum design for HIFU prostate treatments. A 1-D truncated spherical annular array and electronics were fabricated and characterized. In this Phase II application, we propose to build on these encouraging results by: 1) defining and optimizing a HIFU phased array with 2-D focusing capability, 2) fabricating and characterizing the array, 3) integrating it into a transrectal image-guided HIFU probe to be used with the Sonablate system, and 4) evaluating its performance invitro and in-vivo using a canine prostate model. PROPOSED COMMERCIAL APPLICATION: As our population ages, prostate disease (BPH & cancer) is becoming an ever-more-frequent malady for man. The annual market for treatment of prostate cancer in the U.S. is estimated around $5 billion. Focus Surgery Inc. manufactures the Sonablate(TM) system, which makes use of HIFU technology to treat benign prostatic hyperplasia (BPH). To extend the application of this system to treat localized prostate cancer increased flexibility in focal spot placement and less reliance on mechanical steering is required. The current proposal directly addresses this challenge. Successful completion of this project will open the enormous market of prostate cancer treatment to our Sonablate(TM) device.

Project Title: HORMONAL AND ZINC REGULATION OF PROSTATE M ACONITASE Principal Investigator & Institution: Costello, Les C.; Professor; Oral & Craniofacial Biol Scis; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 01-JUN-1996; Project End 30-NOV-2004 Summary: Prostate cancer (PCa) is the second leading cause of cancer deaths in males. The diagnosis, treatment, and prevention of PCa are important contemporary issues. New approaches are required to address this major health problem. Important fundamental information and understanding of the pathogenesis and progression are seriously lacking; which contributes to the slow progress in addressing these issues. Compelling evidence now implicates the involvement of altered zinc accumulation and citrate-related metabolism in the pathogenesis and progression of PCa. The most consistent hallmark characteristic of PCa is the inability of the malignant cells to accumulate zinc and citrate as contrasted with the extremely high accumulation of zinc and citrate associated with normal prostate and benign prostatic hyperplasia (BPH). The consistency of this metabolic change is revealed by the fact that in situ MRS determination of prostate citrate levels now provides the most accurate and sensitive

test for the detection and localization of malignancy. The key reaction in the metabolic transformation of non-malignant citrate-producing prostate epithelial cells to citrateoxidizing malignant cells is mitochondrial (m-) aconitase. The expression and level of maconitase are regulated by hormones (testosterone and prolactin) and by zinc specifically in prostate cells. In this application, the mechanism and specificity of hormonal regulation of the m-aconitase gene in normal and malignant prostate cells will be established. The role of zinc in modulating the activity and equilibrium of maconitase will be investigated. The studies will be performed with normal fresh prostate epithelial cells obtained from rat prostate tissue; and with human malignant prostate cell lines. The long-term objectives are to understand the unique metabolic relationships associated with the alteration of citrate-related metabolism of normal and malignant prostate cells; to establish the role of zinc and hormones in this altered metabolism, and the implications in the pathogenesis and progression of malignancy. This information will provide new approaches to the diagnosis, prevention, and treatment of PCa. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: HUMAN ALDO KETO REDUCTASES AND STEROID HORMONE ACTION Principal Investigator & Institution: Penning, Trevor M.; Professor; Pharmacology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 22-JUN-2001; Project End 31-MAY-2006 Summary: (Scanned from the applicant's description): Human Aldo-Keto Reductases (AKR) of the AKR1C sub-family include 3alpha-, 17beta-, and 20alpha-hydroxysteroid dehydrogenases (HSDs). By acting as ketosteroid reductases or hydroxysteroid oxidases they can either convert potent sex hormones (androgens, estrogens and progestins) into their cognate inactive metabolites or they can form potent hormones by catalyzing the reverse reactions. The synthesis of sex hormones in target tissues is known as their intracrine formation. Our hypothesis is that tissue specific expression of AKR isoforms regulates the occupancy and trans-activation of steroid hormone receptors and provides a pre-receptor regulation of steroid hormone action. In vitro, recombinant AKR1C2 (formerly type 3 3alpha-HSD) and AKR1C3 formerly type 2 3alpha-HSD and type 5 17beta-HSD) function as 3-, 17 and 20-ketosteroid reductases and as 3alpha-, 17beta- and 20alpha-hydroxysteroid oxidases. Both isoforms are expressed in human prostate and AKR1C3 is dominantly expressed in human mammary gland. The role of AKR1C2 and AKR1C3 in androgen, estrogen and progestin metabolism will be studied by transient and stable expression of their cDNA's into CHOP and human embryonic kidney cells, respectively. Forced expression of AKR1C2 and AKR1C3 in androgen receptor (AR; +/ive) prostate cells (LNCaP and PC3) as well as forced expression of AKR1C3 into estrogen receptor (ERalpha; +/-ive) mammary cells (MCF-7 and MDA-MB-435) will elucidate their roles in steroid hormone metabolism and steroid receptor transactivation. AKR 1 C2- and AKR1C3 expression will be measured in normal, benign prostatic hyperplasia and prostatic carcinoma microdissected sections of radical prostatectomy samples using RT-PCR. Co-localization with the AR will be measured by in situ hybridization and immunohistochemistry. Identical techniques will be used to measure AKR 1 C3 expression and its co-localization with the ER and PR in normal and ductal carcinoma regions of breast biopsy samples. These studies will determine whether AKRs co-localize with steroid receptors and whether AKR expression is associated with disease. Selective AKR1C2 and AKR1C3 inhibitors will be developed from two lead compounds, ursodeoxycholate and N-phenylanthranilic acids (e.g. flufenamic acid). These leads will be used to develop transition-state analogs, tight-

binding inhibitors, and mechanism-based inactivators. These inhibitors may provide tools to dissect function and provide routes to the first Selective Intracrine Modulators that target AKRs. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: HUMAN PROSTATIC 3A HYDROXYSTEROID DEHYDROGENASE Principal Investigator & Institution: Lin, Hsueh-Kung; Urology; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2002; Project Start 28-SEP-1998; Project End 31-JUL-2005 Summary: (Adapted from the Applicant's Abstract): In androgen target tissues 3ahydroxysteroid dehydrogenases (3a-HSDs) may regulate the occupancy of androgen receptor (AR) by interconverting 5a-dihydrotestosterone (5a-DHT, a potent androgen) with 5a-androstane-3a,17b-diol (3a-diol, a weak androgen). We have obtained type 2 and type 3 3a-HSD cDNAs expressed in human prostate and overexpressed the enzymes in E. coli. Kinetic studies of these recombinant enzymes show that type 3 3aHSD functions as both a 3a-and 17b-HSD to inactivate active androgens, whereas, type 3 3a-HSD interconverts 5a-DHT with 3a- diol. Levels of 3a-HSD mRNA were higher in primary cultures of prostatic epithelial cells than stromal cells; and elevated levels of 3aHSD mRNA were observed in primary cultures of epithelial cells derived from benign prostatic hyperplasia and prostatic carcinoma tissues. Expression of steady state levels of 3a-HSD mRNA is up-regulated by epidermal growth (EGF) in human prostatic cell lines, LNCaP (androgen sensitive) and PC3 (androgen insensitive). The focus of this proposal is to examine the physiological functions of type 2 and type 3 3a-HSD in regulating androgen metabolism and their activities in modulating prostatic cell proliferation will be investigated. This will be accomplished by stably transfecting type 2 and type 3 3a-HSD cDNAs into these cells. Second, levels of endogenous type 2 and type 3 3a-HSD transcripts will be examined in RNA extracted from the cell lines and normal prostate using ribonuclease protection assay (RPA). Third, EGF-regulated type 2 and type 3 3a-HSD mRNA levels will be examined using RPA. Changes in 3a-HSD expression mediated by EGF will be examined in cell lysates by immunotitration of the enzyme activity. Fourth, to understand the constitutive and EGF- regulated type 2 and type 3 3a-HSD expression in prostatic cells, the 5'-flanking regions of the 3a-HSD genes will be sequenced and cis-acting elements responsible for transcription regulation of two isoforms will be identified.

BLADDER

Principal Investigator & Institution: Levin, Robert M.; Director of Research; Basic & Pharmaceutical Scis; Albany College of Pharmacy 106 New Scotland Ave Albany, Ny 12208 Timing: Fiscal Year 2004; Project Start 01-MAR-2004; Project End 29-FEB-2008 Summary: (provided by applicant): The rabbit model of chronic partial outlet obstruction has proven to be an excellent model for the study of the pathophysiology of human obstructed bladder disease secondary to benign prostatic hyperplasia (BPH). In the rabbit model and in obstructed human bladder tissue, we have identified four defining characteristics of the decompensated (dysfunctional) bladder: 1) cholinergic denervation; 2) mitochondrial dysfunction; 3) decreased sarcoplasmic reticulum (SR) Ca2+ATPase (SERCA) content and activity; and 4) progressive connective tissue (CT)

synthesis and redistribution. Results of our recent studies revealed that the rabbit urinary bladders response to partial outlet obstruction is non-uniform, areas of transient focal hypoxia appeared in the bladder wall during the organs initial rapid growth response to obstruction, before any decrease in net bladder blood flow (BF) was observed. Furthermore, these hypoxic foci were clearly visible within the smooth muscle (SM) compartment during compensated bladder function in chronically obstructed rabbits. In addition, EM examination of mildly obstructed bladders revealed focal damage to nerve and muscle cellular and subcellular membranes, i.e., damage was localized only to specific cells within the fields evaluated. From these studies, we have developed the following hypothesis: Ischemia / reperfusion (I/R) - induced membrane damage originates in areas of transient focal hypoxia that first occur in specific regions of the bladder wall during the organs initial response to partial outlet obstruction and are present during compensated function. In the muscle compartment these hypoxic foci are the initiation sites for the contractile and biochemical dysfunctions and smooth muscle collagen synthesis that continue during progressive decompensation. Progression from compensated function to end-stage decompensation occurs as a result of a graduated change from a focal to global response to focal hypoxia; the shift from compensated to decompensated function occurs as membrane damage and collagen synthesis originating in hypoxic foci spreads into normoxic tissue. A corollary of this hypothesis states that aging is accompanied by a loss of antioxidant potential in the bladder resulting in increased sensitivity to I/R damage and increased rate of progression of obstructive bladder dysfunction. The following are our specific aims: Specific Aim 1: To show that I / R - induced focal hypoxic damage begins during the initial response to partial outlet obstruction and continues into and during compensated function. Specific Aim 2" To show that the shift from compensation to decompensation occurs when membrane damage originating in the hypoxic foci spreads into normoxic areas of the bladder wall and that progression to end-stage decompensation occurs as a result of a shift from a focal to a global organ response to focal hypoxia. Specific aim 3: To show that aging results in decreased antioxidant potential of the bladder and an increase in the progression of obstructive bladder dysfunction.

Project Title: MINIMALLY INVASIVE SURGERY FOR BPH Principal Investigator & Institution: Lieber, Michael M.; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): The objective of this application is for the Department of Urology, Mayo Clinic, Rochester, Minnesota, to become one of the Prostate Evaluation and Treatment Centers (PETC?s) as part of the Minimally Invasive Surgical Therapies (MIST) Treatment Consortium for BPH described in RFA DK-01-024. The purpose of the MIST consortium is to carry out collaborative studies of minimally invasive surgical treatments for lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) over the next five years. Minimally invasive surgical therapies for BPH recently have been recognized as an efficient and cost-effective alternative to standard transurethral resection of the prostate (TURP) and open prostatectomy for certain patients with typical symptoms of prostatism. Most urologists now recognize that minimally invasive surgical therapies occupy a useful niche between pharmacologic therapy and surgical procedures which require inpatient hospitalization. However, as stated in the RFA, published reports about minimally invasive therapies are highly variable in entry criteria and have short periods of follow-up, inadequate documentation of follow-up and adverse events, and absence of information on postsurgical pharmacologic therapy. Most studies have been funded by the device makers and are probably not as objective as studies carried out by an independent group such as the MIST consortium. Because of documented interest in carrying out minimally invasive surgical therapies for BPH at this institution as well as past experience of being a useful member of collaborative consortia studying prostate diseases, we believe we can make a useful contribution to the study of Minimally Invasive Surgical Therapies for BPH as a PETC. As an example of the type of MIST research which could be performed in this initiative, we propose a prospective multicenter randomized Phase III comparison of high power KTP laser vaporization prostatectomy (LVP) versus transurethral microwave thermotherapy (TUMT) using the Urologix Targis T3 device. One hundred seventy patients would be randomized to each treatment arm. Follow-up period would be 2 years post-treatment. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Benign Prostatic Hyperplasia

Summary: (provided by applicant): The George Washington University Biostatistics Center proposes to work in cooperative agreement with the National Institutes of Diabetes and Digestive and Kidney Diseases (NIDDK) to serve as the Biostatistical Coordinating Center (BCC) for the Minimally Invasive Surgical Therapies (MIST) Consortium for Benign Prostatic Hyperplasia (BPH). The prostate surgeries labeled minimally invasive offer exciting treatment alternatives to the gold standard, transurethral resection of the prostate (TURP). The proposed consortium?s objective is to design and conduct up to four randomized, controlled, multi-center clinical trials to determine the long-term efficacy and safety of minimally invasive therapies for symptomatic benign prostatic hyperplasia (BPH). Researchers and investigators from 15 prostate evaluation and treatment centers (PETC), the NIDDK Division of Kidney, Urologic, and Hematologic Diseases, and the BCC will comprise the consortium and collaborate under a cooperative agreement mechanism. The Steering and Planning Committee, composed of the principal investigators from the BCC and each PETC and the NIDDK project officer, will design and develop each of the clinical trials. The BCC will provide centralized support and biostatistical consultation in: the development of protocols, manuals of procedures, data collection forms, and randomization procedures; implementation of a data management system including data quality assessment; interim analysis of protocol performance, patient safety, and treatment efficacy; and final analysis for publication of results in collaboration with the clinical investigators. The BCC will establish a secure encrypted and password protected web site for study staff to enhance development, distribution, and use of study documents. The application includes a proposed protocol for a 3-arm, placebo/sham controlled, randomized, double-blind clinical trial to address whether the apoptotic effect of neoadjuvant and adjuvant finasteride in combination with the thermal effect of high-energy transurethral microwave thermotherapy (TUMT) act synergistically to destroy more BPH mass and improve outcome than either finasteride alone or TUMT alone. Success is defined as at least 30 percent improvement in AUA symptom score. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

The planning for this clinical trial center has been performed to ensure the center?s success in meeting the long-term objectives of the multi-center trial. Specifically, this proposal provides detailed information to establish our ability to meet recruitment goals including minority populations. The following sections outline fail-safe mechanisms in this center design to ensure patient eligibility, data accuracy and efficient data reporting. Two additional considerations central to the design of this clinical center have been the need to maintain patient compliance throughout the duration of enrollment and follow-up, and the need to communicate effectively with the Biostatistical Coordinating Center for this multiinstitutional trial. These tasks will be performed in a timely, efficient, accurate and professional manner to ensure the validity of the data contributed to the trial. This, together with similar contributions from the other clinical trial centers, should allow the

test hypothesis to be answered, specifically to evaluate the safety and long-term efficacy of minimally invasive therapies for lower urinary tract symptoms. Our study center will participate as members of a group of investigators who will conduct multiple randomized clinical trials, either sequentially or concurrently, of minimally invasive devices for the treatment of symptomatic BPH. The investigators from this study center will develop clinical trials and carry out these trails in accordance with centrally approved protocols. The study center at the Medical College of Wisconsin will enroll 180 patients in this clinical trial. The recruitment and marketing strategies outlined in the following sections will ensure this level of participation as well as maximize the center?s ability to recruit minority populations. The center has been designed to provide all the clinical, laboratory and follow-up data required in the protocol. In summary, this proposal outlines what we believe to be the outstanding credentials of the Division of Urology, the Medical College of Wisconsin to serve as a clinical center in this multiinstitutional trial.

Project Title: MINIMALLY INVASIVE SURGICAL THERAPIES TREATMENT CONSORT* Principal Investigator & Institution: Roehrborn, Claus G.; Professor and Chair; Urology; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): Lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) are very common findings in aging men and present a considerable health care burden both in terms of morbidity as well as health care resource utilization. Aside from the standard therapy transurethral resection of the prostate (TURP), medical therapies and minimally invasive surgical therapies (MIST) have been developed over the past decade, which are utilized to varying degreed. Fundamentally, information regarding the relative efficacy and safety, as well as tolerability of these procedures in an outpatient setting under local anesthesia, and importantly, durability of the initial results over intermediate follow-up periods is lacking. Further, due to a lack of understanding of the mechanism of action of some of the treatments, there are no known baseline parameters that could be used as predictors of a successful outcome. The MIST Study Group will develop several clinical trial protocols to address these issues over a 5 year time period. A four-arm randomized trial comparing the safety and efficacy of TURP vs TUMT vs TUNA vs ILTT with a 3 year follow-up is proposed enrolling 600 patients with moderate to severe LUTS and BPH at 15 centers as the first study done by the MIST Study Group with the following objectives: (1). Determine the efficacy of three different minimally invasive surgical therapies (MIST: TUMT, TUNA, Interstitial Laser Thermal Therapy) for LUTS and clinical BPH compared with the standard treatment TURP by electrocautery as measured by a standardized symptom severity assessment instrument (2). Determine the safety and tolerability of three different minimally invasive therapies (TUMT, TUNA, Interstitial Laser Thermal Therapy) for LUTS and clinical BPH compared with the standard treatment TURP by electrocautery (3). Determine the rate of retreatment or secondary treatments following the MIST intervention compared with the standard treatment TURP by electrocautery. (4) Determine whether pre-treatment urodynamic status impacts upon the treatment outcome as defined by symptomatic improvement. (5) Determine the relative efficacy as measured by maximum urinary flow rate, postvoid residual urine volume, prostate volume changes, and serum PSA changes. During the course of this first trial, the MIST Study Group will meet regularly to develop a 2nd,

3rd and subsequent trials. The nature of these additional trials will depend on a needs assessment, the development of new MIST interventions, the findings obtained in the first trial and other factors. The MIST Study Group will be a blueprint for a technology assessment group applicable to other areas of urology and other medical or surgical subspecialties.

Project Title: MOLECULAR ANALYSIS OF COLLAGEN IN NON-COMPLIANT BLADDERS Principal Investigator & Institution: Howard, Pamela S.; Associate Professor; Anatomy and Cell Biology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-SEP-1993; Project End 30-NOV-2003 Summary: (Adapted from the Applicant's Abstract): The major goal of this proposal is to determine the cellular and molecular mechanisms responsible for activation of extracellular matrix genes in bladder fibrosis. Congenital and acquired obstructive uropathies, as the sequelae to neurologic lesions (myelomeningocele, tethered cord syndrome) or physical alteration (posterior urethral valves, benign prostatic hyperplasia, radiation therapy) can result in fibrosis of the bladder wall. The applicant has demonstrated that the terminal response is an accumulation of type III collagen in an abnormal location and an alteration in the ratio of types III to I collagen. To evaluate potential molecular control mechanisms responsible for bladder fibrosis, she will utilize a cell culture model system consisting of human bladder wall cells (detrusor smooth muscle cells and lamina propria fibroblasts) and bladder wall cells from mice which carry genetic mutations in the potential regulatory pathway proteins, transforming growth factor-beta (TGFB) and angiotensin. She will test the hypothesis that extracellular matrix changes in bladder wall cells are regulated by expression of transforming grow factor-beta via a cascade mechanism involving a positive feedback response of angiotensin. She will determine the role of these tissue factors in regulating cell growth (hyperplasia), cell enlargement (hypertrophy) and extracellular matrix gene and protein expression. These experiments will allow determination of the molecular and biochemical impact of each stimulus on a given cell type to determine further what role each cell type within the bladder wall contributes to the pathologic process. In vivo model of mice which have been genetically manipulated to produce less type I collagen or type III collagen, thereby producing a bladder model in which the normal type III: type I collagen ratio has been altered. Using length-tension studies and whole bladder cystometry on these genetically altered bladders; biochemical alterations will be correlated to physiologic functional properties (bladder compliance). We will initiate studies in vivo and in vitro to attempt to identify signaling molecules and transcription factors, which are part of the signaling pathways, which lead to bladder fibrosis.

There is a paucity of information on the molecular basis of prostate regionalization and patterning. In an effort to elucidate the cellular and molecular mechanisms that underlie initiation and maintenance of normal prostate growth, with a long-term view towards understanding the basis of human disease susceptibility, we propose a comprehensive study of regional gene expression in developing prostate glands. Using the mouse as a model system, where zones (termed lobes) are readily dissected, I propose to use a genomic approach to identify genes that are locally expressed during prostate growth and differentiation. A preliminary survey employing differential display analysis has covered approximately 20% of all transcribed genes and identified a number of candidate genes that are region-specific. Further characterization of these genes and their roles in prostate development and differentiation may yield insights into the molecular basis of normal prostate development as well as prostate disease.

Principal Investigator & Institution: Rubin, Mark A.; Associate Professor; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 30-JUN-2005 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) is an extremely common disease of men over age 50. Seventy percent of men by age 60 and 90% by age 70 have histologic evidence of BPH. BPH is clinically manifested by a cluster of lower urinary tract symptoms. A significant cohort of these older individuals exhibit clinical symptoms of BPH. The precise molecular mediators of BPH have yet to be discovered, however, there is considerable evidence that androgens and race play an important role in this process. Before prognostic markers and rational therapies can be developed to target clinically symptomatic BPH, the molecular alterations associated with it need to be unmasked. Our overall hypothesis is that a distinct set of genes/proteins define BPH, molecularly distinguishing it from prostate cancer and non-hyperplastic benign prostatic epithelia. These "signature" molecules have potential as prognostic markers, therapeutic targets, and may play a role in BPH development or progression. The advent of high throughput genomic and proteomic techniques raises new hopes for identifying novel molecular targets for therapy. In this proposal, we will take a functional genomics approach to molecularly dissect BPH. In Aims 1 and 2, gene and protein expression profiles of BPH will be determined using high-density cDNA microarrays and protein microarrays, respectively. Aims 3 and 4 will validate candidate tissue and serum markers using both local and MTOPS samples. Given this, the specific aims are as follows: Aim 1: Define gene expression profiles of BPH. Aim 2: Define focused proteomic profiles of prostatic tissue from BPH patients. Aim 3: Validation of candidate tissue biomarkers of symptomatic BPH a) Tissue Microarray (TMA) Validation using Michigan samples. b) Validation of tissue markers using MTOPS samples. Aim 4: Validation of candidate serum biomarkers of symptomatic BPH. a) Serum Microarray Validation using Michigan samples. b) Validation of serum markers using MTOPS samples.

Benign Prostatic Hyperplasia

Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 30-JUN-2005 Summary: (provided by applicant): Benign Prostatic Hyperplasia (BPH) is a disease of unknown etiology that significantly affects the quality of life in aging men. Histologic BPH may present itself either as symptomatic or asymptomatic in nature. To elucidate the molecular differences underlying BPH, gene expression profiles from the prostate transition zone tissue have been analyzed using microarrays. A set of 511 differentially expressed genes distinguished symptomatic and asymptomatic BPH. This genetic signature separates BPH from normal tissue but does not appear to change with age. This analysis resulted in the identification of several targets, which appear to differentiate BPH from individuals with symptoms from those with histologic BPH. As a Biomarker Unit of the MTOPS Prostate Sample Analysis Consortium we propose to both utilize these markers in a cooperative nature to analyze the tissue and serum samples collected as part of the Medical Therapy of Prostatic Symptoms clinical trial. Our Biomarker Unit will work closely together with the existing MTOPS Data Coordinating Center, the Pathology Coordinating Center as well as the other awarded Biomarker Units. We hypothesize that the genetic markers that we have identified may correlate with the occurrence of BPH as well as the severity of the BPH, responses to pharmacological agents as well as with clinical parameters obtained as part of the study. This hypothesis will be addressed by conducting the following specific aims: 1) to analyze the expression of JM-27, BMP-5 (list other markers) as well as other markers in biopsy samples obtained from the MTOPS trial as well as normal and BPH (symptomatic and asymptomatic) tissues in our bank and to correlate the abovedescribed markers with both response to therapy and symptom progression; 2) to develop serum-based methodologies for testing the expression of the above-described markers in patient samples obtained from the MTOPS trial as well as from normal and BPH (symptomatic and asymptomatic) individuals from our Institution; and 3) to further develop a system by which other markers developed and prioritized by the MTOPS Consortium can be analyzed. As a component of the MTOPS Consortium, these studies should provide the development of novel biomarkers with utility in diagnosing and characterizing BPH.

Project Title: NA CHANNELS IN AFFERENTS AFTER BLADDER OBSTRUCTION Principal Investigator & Institution: Steers, William D.; Professor and Chairman; Urology; University of Virginia Charlottesville Box 400195 Charlottesville, Va 22904 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-MAY-2007 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) develops in one out of four men. In excess of $1 billion is spent to relieve bothersome symptoms of BPH due to an overactive bladder (OAB). These symptoms may include urgency, frequency, nocturia and urge incontinence. Symptoms can be relieved by local anesthetics and minimally invasive procedures that blunt sensory input from the bladder and urethra yet fail to un-obstruct. Using the partial urethral ligation model in rodents, investigators postulate that OAB may originate from changes in muscle and nerves in the lower urinary tract. Obstructed (OBS) rats exhibit urinary frequency and detrusor overactivity temporally correlated to the development of afferent hypertrophy, an enhanced spinal reflex, and a rise in nerve growth factor (NGF). Immunity to NGF prevents both neural plasticity and OAB. Therefore, NGF acting as a cytokine is thought to participate in these events, NGF's ability to influence afferent excitability is thought to derive, in part, from altering Na conductances, which in turn depends on Na channel isoform expression. Data suggests that afferents from OBS rats exhibit decreased

57

immunohistochemical (IHC) staining for the Nay1.8 isoform. This Na alpha subunit gives rise to tetrodotoxin resistant (TTX-R) sodium (Na) currents in C-fiber afferents. Moreover, an antisense (AS) but not mismatch oligodeoxynucleotide (ODN) against this isoform reduces OAB. We postulate that in OBS rats 1) increased afferent excitability exists, 2) OAB and afferent excitability are due to an alteration in sodium (Na) conductance, 3) knockdown of Na channel isoform(s) using intrathecal AS ODN reduces afferent hyperexcitability and OAB, and 4) NGF participates in the genesis of enhanced afferent excitability, alterations in Na channel function and/or isoform expression. These hypotheses will be tested by determining whether obstruction compared to sham surgery 1) alters electrical properties of labeled afferent bladder neurons based on patch clamp analysis, 2) changes expression of Na channel isoforms using IHC and Western blotting, and 3) whether alterations in excitability or protein expression are reversible with deligation and normalization of voiding behavior. The ability of NGF to orchestrate these events will be elucidated by noting if NGF immunity or trkA antagonists prevent changes in electrical properties and protein expression in OBS compared to controls. Insight into these cellular processes could be exploited to develop afferent based treatments for OAB employing pharmacologic, molecular or gene based strategies.

Project Title: NATURAL HISTORY OF PROSTATISM--THE OLMSTED COUNTY STUDY Principal Investigator & Institution: Jacobsen, Steven J.; Professor and Chair, Epidemiology; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-AUG-2005 Summary: The Olmsted County Study of Urinary Symptoms and Health Status among Men is a prospective cohort study of urologic aging in a random sample of over 2,000 community-dwelling men. This study has made a number of significant contributions to our understanding of the natural history of signs and symptoms related to benign prostatic hyperplasia (BPH) that are free from the biases present in clinical series of patients. These findings, however, are limited to an initial ten years of follow-up that was funded by Merck Research Labs. Since BPH is a chronic, progressive disease and complications are manifest over extended periods, the continued follow-up of this cohort is necessary to accrue sufficient events to provide long-term risk information. These data are not presently available but are necessary to make informed clinical decisions. Furthermore, extending follow-up will increase the precision of estimates of change in surrogate measures of BPH, providing better insight into what would be expected in community-dwelling men in the absence of a clinical trial setting. The continued follow-up also will provide a better understanding of how serum PSA levels change over time. The specific aims for this application are designed to expand upon our previous findings with an additional four years of follow-up using our wellestablished protocols. We will determine the 14-year progression of clinical (symptoms), physiologic (peak urinary flow rates) and anatomic (prostate volume) surrogate measures of BPH (Aim 1). We will examine how these vary together over time (Aim 2) and gather information on long-term risk of complications and treatment and relate this to the surrogate measures of BPH (Aim 3). We will also assess the longitudinal changes in serum PSA levels (Aim 4) in order to increase our understanding of the relationship between increases in PSA levels and prostate growth in the absence of cancer. Thus, with the completion of these aims, we will have provided much-needed insight into the role of surrogate measures of BPH in understanding the natural history of this condition

in the community at large. This information will prove useful in the design of future clinical trials and epidemiologic studies. Furthermore, we will have provided information that is necessary for informed clinical decision making for treatment of BPH. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: NKX31 AND PROSTATE DEVELOPMENT AND CANCER Principal Investigator & Institution: Abate-Shen, Cory; Professor; Medicine; Univ of Med/Dent Nj-R W Johnson Med Sch Robert Wood Johnson Medical Sch Piscataway, Nj 088545635 Timing: Fiscal Year 2002; Project Start 01-SEP-1998; Project End 30-JUN-2003 Summary: (adapted from investigator's abstract): Inductive signaling interactions between epithelial and mesenchymal cell layers represent one of the principal mechanisms of vertebrate organogenesis. In particular, the prostate arises late in gestation when signals from urogenital sinus mesenchyme induces the urogenital sinus epithelium to form the prostatic buds. Under the influences of androgens, these epithelia buds elongate and undergo ductal morphogenesis, thereby forming the ventral, dorsolateral, and anterior (coagulating gland) lobes of the rodent prostate. The prostate provides an excellent model system for studying inductive epithelialmesenchymal interactions, the role of androgen signaling in the generation of sexual dimorphism, and the molecular mechanisms of ductal morphogenesis. Moreover, the analysis of prostate development is likely to provide insights into human disease, notably benign prostatic hyperplasia (BPH) and prostate carcinoma. The Principal Investigator has identified a novel homeobox gene, termed Nkx3.1 that appears to play an important regulatory role in prostate development. Nkx3.1 is one of the few transcriptional regulators known to be expressed specifically in the prostate during development and adulthood. Importantly, the preliminary analysis of Nkx3.1 null phenotype has demonstrated that Nkx3.1 is required for normal prostate development and function. The regulatory role of Nkx3.1 in prostate development will be investigated by performing a detailed analysis of its biochemical properties, expression pattern, cellular activities, and biological functions as follows: 1) the biochemical properties of the Nkx3.1 protein will be analyzed by examining its requirements for DNA recognition, its transcriptional properties, and its post-translational modification by phosphorylation; 2) the expression pattern and cellular functions of Nkx3.1 will be analyzed by examining the distribution of murine Nkx.3.1 transcripts and protein in the male urogenital system, and investigating the effects of Nkx3.1 on cell proliferation and transformation; and 3) the biological role of Nkx3.1 in development will be analyzed by investigating its role in the male urogenital system, by examining its cell autonomy, and its over-expression in reconstituted prostatic tissue.

development increase with the ageing process. We propose that a component of the prostate microenvironment that may 'evolve' during the ageing process and increase the risk for BPH development and progression, namely, the relationship between epithelial and associated fibroblastic cells. To test this possibility, we propose to utilize an in vitro model system developed in our laboratory. The epithelial component of this model comprises N15C6 cells that genotypically and phenotypically resemble primary prostate epithelial cells, and the stromal component consists of fibroblastic cell populations originating from young, middle-aged or elderly cystoprostatectomy patients. Preliminary data utilizing this in vitro model system demonstrates that paracrine interactions with fibroblast cells alter genotypic expression and augment expression of the proliferative phenotype in immortalized epithelial cells. Therefore, this in vitro model system could recapitulate the 'evolution' of paracrine interactions between prostate epithelial cells and associated fibroblastic cells during the ageing process. Based on data acquired from this model, we hypothesize that the composition of proteins secreted by fibroblast cells derived from young, middle-aged and elderly patients may differ in a patient age-dependent manner. If so, we expect that human prostate epithelial cells may respond differentially, both phenotypically and genotypically, to the particular medley of proteins secreted by fibroblast cells derived from young, middleaged and elderly patients, and vice versa. This work will be accomplished through the completion of three specific aims: Specific Aim 1. Elucidate the influence of an ageing tissue microenvironment on prostatic proliferation. Specific Aim 2. Isolate fibroblast- or epithlelial-secreted factors that augment expression of the proliferative phenotype. Specific Aim 3. Elucidate how genotype drives phenotype in the context of an ageing prostate tissue microenvironment. The results of these studies should define the specific epithelial- and fibroblast-secreted proteins and their downstream effectors that augment expression of the proliferative phenotype in the human prostate.

Project Title: PHYTHOTHERAPY FOR THE TREATMENT OF BPH SYMPTOMS Principal Investigator & Institution: Foster, Harris E.; Associate Professor; Surgery; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-MAR-2009 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) is the most common non-malignant neoplasm in the aging male. The number of men with lower urinary tract symptoms secondary to BPH, is expected to increase substantially as the population ages. Interest in using complementary and alternative medicines, such as phytotherapy, to prevent and manage health care needs has increased dramatically in recent years. The use of phytotherapy to relieve lower urinary tract symptoms, particularly BPH, has spurred interest in Serenoa repens (Saw palmetto) and Pygeum africanum. Both phytotherapeutic agents are used extensively in this country to relieve symptoms of BPH, but little is known about their mechanism of action, efficacy, safety, or the side effects. Although a number of randomized placebo-controlled trials have been published, all suffer from a variety of shortcomings. A long-term randomized placebo-controlled trial is needed to determine if Serenoa repens or Pygeum africanum prevents clinical progression of BPH. Secondary objectives should include a direct comparison of the two phytotherapeutic agents in their ability to improve the symptoms of BPH, the relationship between prostate size and clinical progression of BPH or regression of symptoms, and the ability of objective diagnostic studies to determine which patients are optimal candidates for phytotherapy. The primary goal of this application is to emphasize the ability of Yale University School of Medicine and Yale

Project Title: PILOT--SCAN FAMILY MEMBERS IN THE GENITOURINARY TRACT Principal Investigator & Institution: Collins, Tucker O.; Professor; Chldrn's Hospital Corporation Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2008 Summary: Growth factor signaling systems play a central role in cellular physiology and have been implicated in a wide range of pathophysiologic responses. In the urogenital system, these conditions include benign prostatic hyperplasia and bladder hypertrophy resulting from obstructive uropathies. Because growth factors can elicit such profound changes in cellular responses, understanding the regulation of expression of these mediators should provide important insights into these adaptations. Transcriptional control mechanisms are thought to play a role in altering the levels of the growth factors expressed by the cells of the urogenital system. One class of transcription factors implicated in both the positive and negative regulation of growth factor genes is the C2H2 type of zinc finger factor. With more than 700 C2H2 zinc finger proteins in the human genome, this is a largely unexplored group of regulators. Some of the C2H2 zinc fingers are associated with conserved functional motifs, such as the SCAN domain. The SCAN domain is a highly conserved 84-residue dimerization motif that is found at the N-terminus of about 10% of C2H2 zinc finger proteins. An attractive possibility is that the domain generates combinatorial diversity within the SCAN family of proteins. Despite the large number of members in this family, remarkably little is known about the domain itself or the functions of most of the proteins defined by the domain. However, some members of the family have been implicated in the regulation of growth and survival factors and preliminary studies suggest that SCAN family members are expressed by some of the cells of the urogenital system. The central hypothesis of this developmental project is that members of the SCAN-ZFP transcription factor family play a key role in the regulation of genes important in tissue renewal in the genitourinary tract. To further investigate this hypothesis, we propose two specific aims to define the relevant SCAN family members and the genes they regulate: Specific Aim 1: Characterize the spatial and temporal expression pattern of selected SCAN-ZFP in the urogenital system; Specific Aim 2: Identify candidate target genes in the genitourinary tract that are transcriptionally regulated by SCAN-ZFP. Collectively, these studies should provide new information about the SCAN family and its target genes in the urogenital system. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: PROSTATE GENE EXPRESSION CHANGES ASSOCIATED WITH BPH Principal Investigator & Institution: Slawin, Kevin M.; Associate Professor; Urology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 30-JUN-2005 Summary: (provided by applicant): Through this application, Baylor College of Medicine responds to RFA: DK-02-017, MTOPS Prostate Samples Analysis Consortium (MPSA). The Baylor Prostate Center proposes to serve as a Biomarker Unit within the MPSA consortium, which will work cooperatively with the other Biomarker Units, the Pathology Coordinating Center, and the NIDDK Project Coordinator to perform basic and translational research on biomarkers for BPH. The PI, Kevin M. Slaw/n, M.D., Director of the Baylor Prostate Center, recruited and managed 200 patients on the MTOPS trial over its seven-year duration. The co-investigators encompass broad interests and expertise in both clinical and basic research in benign prostatic hyperplasia (BPH), molecular epidemiology, biomarkers research, genetic and tissue microarray technology, cell signaling, and sophisticated data mining and statistical analysis of complex biologic data. Drawing from his extensive BPH clinical trials experience and with the resource management skills gained as co-Director of both the Biopsy and the Basic Tissue Research Committees of the MTOPS trial, as the Serum Bank director and member of the Resource Allocation Committee of the Baylor SPORE in Prostate Cancer, and as director of Baylor's Prostate Cancer Screening Program for the past eight years, the PI has the requisite administrative, clinical and basic research experience in BPH and biomarker development and validation to lead this center. Furthermore, the considerable tissue resources available through BPH-sub-studies of the Baylor SPORE in Prostate Cancer, and the expertise in tissue harvesting, cataloguing and banking, and in tissue microarray development and production will serve as a valuable resource for biomarker validation prior to testing on the invaluable and limited MTOPS tissue for the Baylor Center, as well as, for the other MPSA consortium members. Our large prostate cancer screening serum bank, containing frozen sera obtained through a yearly program, contains serial frozen serum samples and clinical data including IPSS, DRE estimated prostate volume, and medical and surgical treatment history for BPH on over 10,000 patients spanning a decade of follow-up. Serum markers that correlate with the presence and severity of BPH or that predict progression or response to medical therapy, identified either by the Baylor Biomarkers Center, or by other Centers could be validated in a Phase II study with these resources, allowing only the best markers for progression to evaluation in Phase III studies using the exhaustible MTOPS serum and tissue bank resources. Through the efforts of this RFA proposal, the Baylor MPSA Center, along with the other centers, the Biostatistics Center and the NIDDK, hopes to answer identify and validate much needed new biomarkers for the detection of BPH and the assessment of risk for disease progression, as well as to gain insight into the molecular correlates that determine response to medical therapies, primarily a-blockers and 5a-reductase inhibitors for this disease.

Benign Prostatic Hyperplasia

Summary: (provided by applicant): In the proposed research, we plan to develop methods that examine the humoral response to prostate tumor antigens as a diagnostic and prognostic serum biomarker of disease. The method involves the use of protein microarrays produced by the two-dimensional liquid phase fractionation of cell lysates. A pl-based chromatographic separation is utilized in the first dimension to fractionate large numbers of proteins into discrete pH fractions over an extended pH range. In the second dimension, nonporous (NPS) reversed phase (RP) HPLC of each pH fraction will be used to separate out purified proteins to be spotted from the column eluent onto nitrocellulose slides. The result will be a protein microarray consisting of >2500 protein spots that can be tested against patient sera to examine resulting humoral response. The prostate cancer protein microarrays will be used to interrogate serum from healthy control individuals, patients with benign prostatic hyperplasia (BPH), and those with biopsy-proven prostate cancer. Using this approach, we hope to characterize a signature humoral response for patients with prostate cancer. The method arrays proteins from actual tumor cells so that antibodies in patient plasma may react to modified forms of a protein not necessarily produced by other methods. Proteins eliciting a humoral response to serum can be analyzed directly from liquid fractions by mass spectrometry where an accurate MW value and analysis of enzymatic peptide maps by CE-TOF-MS and MALDI-TOF-MS can be used for identification and determination of present modifications. Modified proteins may provide selective response to antibodies in sera that unmodified proteins may not provide. The presence of proteins in the liquid phase makes this method amenable to automated screening of large numbers of samples. The antibody response will be explored for its utility in screening/diagnosis (i.e. to supplement PSA testing) and prognosis (i.e., distinguish between indolent and aggressive prostate cancer). In addition, bioinformatic methods will be used to determine whether subclasses of prostate cancer exist that better discriminate among clinical outcomes. A predictive model will be developed cataloguing clinically meaningful markers based on humoral expression profiles from localized prostate cancer samples; thus, candidate tumor antigens can be identified for further experimental study. Candidate tumor antigens will be further validated using tissue microarrays. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: REGULATION OF HUMAN PROSTATE EPITHELIAL CELL GROWTH Principal Investigator & Institution: Ware, Joy L.; Professor; Pathology; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2002; Project Start 18-MAY-1998; Project End 28-FEB-2006 Summary: (provided by applicant): Two diseases of the prostatic epithelium, benign prostatic hyperplasia (BPH) and prostate cancer, are among the major health problems faced by American men. Deregulation of prostatic epithelial cell proliferation is a central event in both benign and malignant prostatic disease about The objective of this application is to determine the mechanism(s) by which insulin-like growth factor (IGF) and epithelial growth factor (EGF) regulate the growth of human prostate epithelial cells, with emphasis on interactions between the IGF receptor, EGF receptor and the androgen receptor (AR) networks. The hypothesis to be tested is that androgen-induced genes also inducible by IGF or EGF provide an alternate mechanism for control of prostate epithelial cell proliferation and behavor. We will use a novel, well characterized family of SV40TAg immortalized human prostate epithelial cells, both androgen receptor negative (M12AR-) and androgen receptor positive (M12AR+) to achieve these specific aims: (1) To identify key genes induced in common in androgen receptor positive Ml2 cells by both androgen (DHT) and IGF or EGF by applying cDNA microarray analysis; (2) To determine the mechanism(s) by which IGF and EGF regulate prostate cell growth in vitro and in vivo. Candidate genes will be either over expressed or reduced in expression in the appropriate cell line by transfection or introduction of morpholino antisense oligonucleotides or antisense constructs. Proliferation, apoptosis, and differentiation will be assessed in vitro and in vivo by orthotopic injection into athymic nude mice; (3) To determine the expression patterns of the IGF, EGF, and androgen regulated genes identified in Aim 1 among human benign and malignant prostatic tissues. Prostate tissue arrays will be prepared from 400 prostate cancers and screened by immunohistochemistry or in situ hybridization, to confirm expression and assess the frequency of expression of the genes evaluated in our experimental system. These studies will provide comprehensive and unique insights into the mechanisms by which peptide growth factors provide alternate pathways to control prostate epithelial cell proliferation in benign and malignant states.

Project Title: ROLE OF FIBROBLAST GROWTH FACTORS IN PROSTATE GROWTH Principal Investigator & Institution: Ittmann, Michael M.; Professor; Pathology; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 30-SEP-1997; Project End 31-AUG-2004 Summary: (Adapted from the Applicant's Abstract): Benign prostatic hyperplasia (BPH) is an extremely common disease of older men which leads to morbidity by obstructing urine outflow. There is a considerable body of evidence implicating increased estrogen, in conjunction with androgens, as an underlying factor in the etiology of BPH, but the mechanism by which these hormonal alterations lead to BPH is unclear. The investigators have shown increased expression of FGF7 and FGF2 in BPH that is correlated with epithelial and stromal proliferation, respectively. The role of androgens and estrogens in controlling FGF7 and FGF2 production in the prostate is either controversial or unknown. They have also shown that paracrine factors secreted by prostatic epithelial cells can stimulate production of FGFs by prostatic stromal cells. For FGF7 this paracrine factor is IL- 1alpha. FGF 17, which can increase proliferation of fibroblastic cells, is also expressed by prostatic epithelial cells. Their hypothesis is that increases in estrogen, in combination with androgen, can synergistically stimulate FGF2 and FGF7 production by stromal cells in BPH, which can be further stimulated by local, epithelial derived paracrine factors that both induce FGF production and enhance proliferation of FGF producing stromal cells. They propose two Specific Aims: Specific Aim 1: Control of FGF7 and FGF2 expression by androgens and estrogens: Using primary cultures of human stromal cell they will assess the effect of androgens, estrogens, and paracrine epithelial factors, alone or in combination, on FGF7 and FGF2 production. They will then determine the mechanism by which FGF protein expression is increased in response to the inducing factors. Finally, they will evaluate the effects of androgens and estrogens on FGF production and proliferation using an in vivo model system in which human tissue is implanted in scid/hpg mice. Specific Aim 2: Control of FGF7 and FGF2 expression by paracrine epithelial factors: Their first goal is to correlate expression of IL- Ialpha with expression of FGF7 to test their hypothesis that FGF7 production can be driven by IL- 1alpha. In vivo they will derive a transgenic mouse line that expresses IL- 1alpha at high concentrations in the prostate and determine whether there is induction of FGF7 expression in parallel with hyperplasia of the prostate. The second goal is to identify the epithelial derived paracrine factor(s) which induces FGF2 production by stromal cells. Their final goal is to define the role of FGF 17 as an epithelial derived paracrine inducer of stromal cell proliferation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ROLE OF IGFBP 2 IN PROSTATE--AGE RELATED CHANGES Principal Investigator & Institution: Chakrabarty, Shilla; Anatomy and Neurosciences; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2005 Summary: The prostate gland is known to become hyperproliferative and display a propensity toward carcinoma, with progression in age. As a result, the frequencies of benign prostatic hyperplasia (BPH) and prostate cancer increase dramatically in elderly men. The Insulin-like growth factor (IGF) system is being increasingly recognized as an important regulator of prostatic functions. Insulin like growth factor binding protein-2 (IGFBP-2) may play a significant role in prostatic growth because: (a) it is a major prostatic binding protein; (b) serum IGFBP-2 levels increase with age; and (c) circulatory

levels of the protein are dramatically higher in prostate cancer patients compared to those with BPH, or in normal subjects. The role of IGFBP-2 in prostatic growth has not been studied to date. Our preliminary studies with prostate cancer cell lines suggest that IGFBP-2 potentiates the growth of prostate cancer cells by up-regulating IGF-I, while IGFBP-2 antibody (Ab) inhibits these effects. No significant growth modulating effects of IGFBP-2 or its antibody were found on normal prostate epithelial cells obtained from a 40 year old single donor. Based on the results of our preliminary studies, and the fact that prostate cancer develops in old age, I hypothesize that IGFBP-2 is involved in the age-dependent transformation of the prostate from normal to metastatic disease. I speculate that elevation of circulatory IGFBP-2 with age induces malignant transformations in the prostate by up- regulating IGF-I, and by modulating IGF cellular actions. To test my hypothesis, the specific aims of the current proposal are to: (1) study age-related and lobe-specific changes in the morphology and expression of IGF system components in the prostate of rodent models of spontaneous hyperplasia and prostatic carcinoma, and relate these to circulatory levels of IGFBP-2; (2) explore if exogenously administered IGFBP-2 or its antibody can modulate the incidence of malignant transformations in the prostate of rodent models of spontaneous hyperplasia and prostatic carcinoma; (3) examine if IGFBP-2 can modulate the tumorigenic potential of normal and malignant prostatic epithelial cells in vivo and in vitro, and (4) investigate the molecular mechanisms by which IGFBP-2 modulates the growth of normal and malignant prostatic epithelial cells. The importance of the proposed studies lies in the fact that besides establishing a knowledge base on age-related changes in the role of IGFBP-2 in the prostate, it will create new grounds for targeting IGFBP-2 in the early diagnosis, progression, management and treatment of prostate cancer, which affects a large population of elderly men.

Project Title: SAW PALMETTO EXTRACT IN BENIGN PROSTATIC HYPERPLASIA Principal Investigator & Institution: Avins, Andrew L.; Assistant Clinical Professor; Northern California Institute Res & Educ 4150 Clement Street (151-Nc) San Francisco, Ca 941211545 Timing: Fiscal Year 2001; Project Start 23-AUG-1999; Project End 31-AUG-2004 Summary: This proposal describes a double-blind, placebo-controlled randomized clinical trial of the effect of saw palmetto extract on symptoms, objective parameters of disease severity, and quality of life in men with moderate-to-severe benign prostatic hyperplasia. BPH, one of the most common morbid medical conditions in middle-aged and elderly men, is generally treated with alpha-adrenergic blocking agents, finasteride, surgical interventions, or no specific therapy ("watchful waiting"). In the past several years, however, many patients have begun to self-medicate with an extract of the saw palmetto plant (Serenoa repens), a medicinal herb grown in the southeastern United States. Saw palmetto has become the fifth leading medicinal herb consumed in the U.S. and is considered first-line therapy for BPH in several Western European countries. Several small studies suggest that saw palmetto may have clinical benefit, but the methodologic quality of most prior studies has been poor. Very few side effects of the herb have been observed, but few studies have been conducted for more than three months. We propose to conduct a high-quality clinical trial of saw palmetto, with careful attention to the methodologic deficiencies of prior studies. After a single-blind placebo run-in period, 224 patients with mode moderate-to-severe BPH (American Urological Association Symptom Index score greater than or equal to 8) and objective measurement of urinary obstruction, will be randomized to receive either 160mg BID of the herbal

extract or an identical placebo. Patients will discontinue any other medical therapy for BPH prior to enrollment and all participants will undergo a trans-rectal ultrasound examination at baseline and closeout. Participants in the trial will be seen at 3-month intervals for a total one-year follow-up. Outcome measurements include changes in the AUASI score (the primary outcome measurement), the peak urinary flow rate, the postvoid residual urine volume, the BPH Impact Index, the Olmstead County Study Questionnaire of BPH-specific symptoms and quality of life, and the Short-Form 36 (a generic health status instrument). Numerous laboratory parameters will measured at intervals throughout the trial and symptomatic side effects will be assessed. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: SAW PALMETTO USE AND RISK OF PROSTATE CANCER Principal Investigator & Institution: Lee, I-Min; Assistant Professor of Medicine; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2003; Project Start 18-SEP-2003; Project End 31-AUG-2005 Summary: (provided by applicant): Apart from non-melanoma skin cancer, prostate cancer is the most commonly diagnosed cancer among men in the United States today. In spite of its importance, few modifiable predictors of this disease have been established. Well-established risk factors for prostate cancer (e.g., age) are not amenable to modification and, hence, have limited utility as targets of primary prevention strategies. There is a need to identify other risk factors that can be controlled. 5-alpha reductase, the enzyme that converts testosterone to dihydrotestosterone, has been proposed to play a key role in the etiology of prostate cancer; thus, the NCI is currently testing finasteride, a 5-alpha reductase inhibitor, in the prevention of prostate cancer in an ongoing, randomized clinical trial. No information is available on other agents capable of inhibiting 5-alpha reductase and prostate cancer risk in men. Saw palmetto, derived from the berry of the American palm tree, can inhibit 5-alpha reductase activity. Saw palmetto has been shown to be as effective as finasteride in the treatment of urinary symptoms from benign prostatic hyperplasia. No data are available regarding its association with prostate cancer incidence in men; however, in vitro studies show inhibition of growth of prostate cancer cell lines. Therefore, we propose to conduct a retrospective cohort study among 16,700 physicians (mean age 67 years) to test the hypothesis that saw palmetto use reduces the risk of developing prostate cancer. These men currently are being followed as part of two other funded studies, the Physicians' Health Study I and II. Information on the development of prostate cancer is being collected in these two studies, as is a whole host of other information on health habits and medical history. In this application, we propose to retrospectively collect details on the use of saw palmetto (when started and stopped, dose, brand) by adding questions to the scheduled 72-month follow-up questionnaire in these two other studies. During the proposed period of study, we anticipate that 790 cases of prostate cancer will develop. Power calculations show adequate power to detect a 45% reduction in risk of prostate cancer associated with saw palmetto use. At little additional cost, the data from this study will contribute to the knowledge infrastructure regarding whether large scale, informative trials on saw palmetto use and prostate cancer risk should be supported in the future.

Timing: Fiscal Year 2002; Project Start 07-JUL-1997; Project End 30-JUN-2006 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) has been postulated to arise from reactivation of embryonic growth pathways. The major goal of our research is to identify the molecular mechanisms that initiate fetal prostate development and to understand how reactivation of these mechanisms in the adult might cause hyperplasia. The prostate is an accessory exocrine sex organ composed of a secretory ductal system enmeshed in a supporting stroma. During fetal development, buds of urogenital sinus (UGS) epithelium grow into the surrounding mesenchyme and form ducts that grow and branch to form a complex ductal system. We have identified two important regulators of ductal development that exert opposing effects on growth. The first is the gene sonic hedgehog (Shh). Shh expression is upregulated by testosterone and localizes to the epithelium of buds that form the main prostatic ducts and to the epithelium of the growing prostatic ducts. The Shh gene product is a secreted signaling peptide that activates target genes in the adjacent UGS mesenchyme. Shh stimulates epithelial proliferation, induces budding in the UGS and promotes ductal branching during postnatal prostate development. The second factor is the gene Bone morphogenetic protein 4 (Bmp4). Bmp4 is expressed in the UGS mesenchyme. Expression surrounds sites of ductal budding and ensheaths the developing prostate ducts. Bmp4 inhibits epithelial proliferation, restricts ductal budding and restrains ductal branching. Our studies reveal that Shh and Bmp4 are expressed in tightly coordinated, complementary patterns of expression that echo their opposing influences on ductal growth. We propose to evaluate the hypothesis that Shh and Bmp4 collaborate to control prostate ductal budding and branching. We expect to show that Shh and Bmp4 act as independent regulators that control ductal growth by exerting opposing effects on epithelial proliferation. We will characterize the effects of Shh and Bmp4 on ductal growth, link their expression to the influence of testosterone and a regulator of ductal budding (Hox-dIS), and characterize the effects of Shh overactivity and Bmp4 insufficiency on ductal budding and branching. We expect to provide new insights into the regulation of prostate growth that will have particular significance in light of our recent observation that Shh and Bmp4 are re-expressed in BPH.

Project Title: STEM CELLS AND DISEASE SUSCEPTIBILITY IN THE PROSTATE Principal Investigator & Institution: Masters, John R.; U of L University College London University College London London, Timing: Fiscal Year 2002; Project Start 01-MAR-2001; Project End 31-JAN-2004 Summary: (Adapted from the Applicant's Abstract): The prostate gland is the site of two of the most frequent diseases that afflict elderly men: benign prostatic hyperplasia (BPH) and prostate cancer. The etiology of both diseases is thought to involve changes in prostate stem cells, the cells that are responsible for the growth and maintenance of the prostate gland. BPH and prostate cancer arise in different zones of the prostate. If the differences in stem cell biology between the different zones of the human prostate are elucidated, it may be possible to identify the factors regulating the major differences in susceptibility to prostate disease and design more effective means of controlling BPH and prostate cancer. The specific aims are to identify the epithelial stem cells in each zone of the human prostate and provide the resources for comparative analysis of gene and protein expression in stem cells of these different zones. The project will use normal human prostate tissue to (1) identify, isolate and characterize the epithelial stem cell population from each zone using flow sorting and lineage analysis, (2) to compare the patterns of differentiation between the zones using multiple immunostaining, and (3) to

grow and store at least 3 large scale primary cultures of epithelial and mesenchymal cells derived from each zone for future analysis using DNA microarrays and proteomics. It is proposed that this project will lead to a greater understanding of why these two important diseases of elderly men develop in different parts of the prostate and provide the resources needed to develop new strategies for the prevention, management and therapy of BPH and prostate cancer.

We have reported the cloning of full length cDNA (rat and human) and genomic DNA (mouse and human). The ps20 protein is a new member of the whey acidic protein (WAP) family. This family exhibits growth and differentiation functions. We have made antibody probes to ps20, localized ps20 expression to smooth muscle cells (SMC) in vivo, produced recombinant biologically active ps20, localized ps20 gene to human chromosome 16q24.3, and identified CD9 as a putative membrane interacting/signaling protein. Expression of ps20 was preferential to smooth muscle in vivo, including prostate gland and vascular smooth muscle. Recombinant ps20 induced phenotypic modulation of prostate smooth muscle cells to the migratory, synthetic phenotype in vitro, characteristic of hyperplastic SMC in vascular wall (atherosclerosis) diseases and in culture. In addition, ps20 blocked TGF-beta1 induced phenotypic modulation of SMCs to the contractile phenotype and maintained cells in the synthetic phenotype. Expression of ps20 was specifically regulated by TGF-beta1 in smooth muscle, suggesting an autocrine negative feedback loop. Immunoprecipitation-Western experiments suggests an interaction between ps20 and the CD9 membrane protein in SMCs. These studies suggest ps20 may be a fundamental mediator of smooth muscle phenotype. Benign prostatic hyperplasia (BPH) is a stromal-based disease typified by hyperplastic smooth muscle and ps20positive SMCs. The present proposal will address the hypothesis that ps20 functions as a key autocrine regulator of synthetic SMC phenotype and that ps20 and the synthetic SMC phenotype play roles in the genesis of BPH. To extend our studies and address this hypothesis in detail we propose: l.) To define the ps20-induced smooth muscle phenotype and identify specific ps20-interacting proteins. 2.) To determine whether there is a correlation between expression of synthetic smooth muscle markers, a nodular BPH phenotype, and ps20 expression in human BPH specimens; 3.) To determine the in vivo function of ps20 by targeted gene knockout in mice, and; 4.) To determine the inductive function of ps20 in vivo by targeted overexpression using prostate tissuetissue recombination mouse models.

Summary: (provided by applicant): My long-term goal is to study the biology of stromal-epithelial interactions in benign prostatic hyperplasia (BPH). Since development, growth and tumorigenesis in the prostate is closely regulated by the stromal-epithelial crosstalk, identifying the signal transduction pathways between prostate epithelial cells and the surrounding stromal cells will enable us to better understand the normal and abnormal biology in prostatic diseases. I hypothesize that expression of particular stromal genes is one of the components that regulates the proliferation, cell death and differentiation of prostatic epithelial cells leading to BPH in adulthood. The Jun-family proteins that are early transcription factor molecules have been shown to regulate stromal-epithelial interactions via paracrine modulation. Moreover, the Jun family member proteins have been shown to play an important role in proper development of the genitourinary organs. The balance between the different Jun-family expression in the stroma may be one of the determinants of the ultimate survival or death signals that the stroma may exert on prostatic epithelial cells. This proposal will address whether paracrine signals form stromal cells with genetically modified Jun-family proteins can regulate epithelial proliferation, cell death and differentiation. Stromal expression of Jun-family proteins will be examined in relation to signal transduction pathways known to be important in prostatic stromal-epithelial interactions. These studies can improve our understanding of normal and abnormal stromal-epithelial interactions that may lead to BPH in adulthood.

Project Title: SYSTEMATIC ASSESS OF GENE EXPRESSION IN MOUSE PROSTATE Principal Investigator & Institution: Chen, Yong Q.; Associate Professor; Cancer Biology; Wake Forest University Health Sciences Winston-Salem, Nc 27157 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-AUG-2003 Summary: Although our understanding of the molecular mechanisms that underlie early development of the vertebrate embryo has advanced dramatically, there has been much less progress in clarifying the processes that orchestrate the formation of the elaborate structures that make up many of the body's organ systems. Elucidating early steps in genitourinary tract development and subsequent steps in determining and differentiating prostate cell lineages is expected to identify genes important in prostate diseases such as benign prostatic hyperplasia and prostate cancer. Cancer of the prostate is the most commonly diagnosed cancer in males in the United States and is the second leading cause of cancer death in men. Many risk factors for human prostate cancer have been proposed, however, its exact etiology is still largely unknown. Since a wide variety of genetic and genomic approaches are possible in the mouse, systematic assess gene expression of the developing mouse prostate will provide an extremely valuable database for research using this species. In turn, genetic studies in mice are likely to further our understanding of the mechanism of human prostate cancer development. We propose to systematically catalog cell-specific patterns of gene expression in mouse prostate. (1) We will quantify genes that are expressed in the stroma, basal and columnar epitheial cells of the mouse ventral, lateral, dorsal and anterior prostate by microSAGE. A total equal to or greater than1,350,000 transcripts will be determined, with which we will have a 96.6% chance to identify genes that are expressed at 1 copy/cell level. (2) We will compare the gene expression profile between the stroma and epithelial cells in different anatomical locations of the mouse prostate (a total of 75 comparisons). We will confirm SAGE results by real-time PCR quantitation. We will post results on our web site so that the data are available to the entire research

community. (3) We will compare genes that are differentially expressed during the human prostate tumor progression from normal to BPH, PIN, carcinoma and bone metastases to genes that are expressed in mouse prostate to identify mouse homologues/orthologues. Our study will provide the first comprehensive mouse prostate gene database. More importantly, we will provide a list of candidate genes that are likely to be involved in prostate tumor progression. The data should be a rich, valuable resource for devising future genetic targeting, animal modeling and other experiments related to developmental biology in general and prostate cancer in particular.

Project Title: THE EFFICACY OF TUMT AND NEOADJUVANT FINASTERIDE FOR BPH Principal Investigator & Institution: Mcvary, Kevin T.; Associate Professor; Urology; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) is the most common neoplastic condition afflicting men and constitutes a major factor impacting the health of the American male. The objective of the Minimally Invasive Surgical Therapies (MIST) Consortium for BPH is to design and conduct up to several randomized, controlled, multicenter clinical trials to determine the long-term efficacy and safety of minimally invasive therapies for symptomatic BPH including Transurethral Microwave Thermotherapy (TUMT). The potential advantages of TUMT include the relief of LUTS with an in-office procedure using minimal anesthesia and a rapid recovery. TUMT has been enthusiastically applied to patients with BPH, but reports suffer from lack of uniform outcome measurements and little data on post-surgical pharmacological treatment. One of the goals stated in the RFA is to assess whether adjuvant medical therapy improves the long-term outcome of MIST. In this light, we hypothesize that finasteride can augment the necrosis of prostatic tissue undergoing TUMT by virtue of it ability to induce TGF-beta mediated apoptosis. We propose that this known effect of finasteride will increase the "thermal kill" when used in a neoadjuvant setting with TUMT and result in an improved outcome. This is a truly exciting research direction, with considerable potential ramifications for both the patient and the health care delivery system. We propose an initial clinical trial to address whether the apoptotic effect of neoadjuvant and adjuvant finasteride in combination with the thermal effect of TUMT act synergistically to destroy more BPH mass and improve outcome than either finasteride alone or TUMT alone. We are proposing a 3-arm, placebo/sham controlled, randomized clinical trial using changes in symptoms as the primary Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

become apparent that androgens, while necessary, are not sufficient for full prostate growth or for the development of BPH. The sympathetic division of the autonomic nervous system controls prostate smooth muscle tone through the action of the sympathetic catecholamine neurotransmitter norepinephrine (NE) on G-protein coupled alpha1-adrenoceptors (alpha1-ARs). There is also compelling evidence from rat and human models that the action of NE on alpha1-ARS stimulates cell proliferation in the prostate independently of androgens. Furthermore, sympathetic activity is known to increase with aging in man and human BPH is associated with clear indications of aberrant sympathetic neurotransmission including alterations both in the number of noradrenergic nerves and in the expression of the mRNAs encoding the three alpha1AR subtypes. These findings indicate that the sympathetic nervous system represents an important androgen independent prostatic growth mechanism. It is our hypothesis that increased sympathetic activity is a critical factor in the causation of BPH. We further hypothesize that increased sympathetic activity results in the altered expression pattern of the alpha1-AR subtype mRNAs seen in BPH which in turn results in increased cell proliferation. We will systematically test our hypothesis by dissecting the mechanism involved in the mitogenic activation of prostatic alpha1-ARS by NE. Specifically we will activate or inhibit specific steps in this signaling pathway and examine the consequences on cell proliferation, cell apoptosis and alpha1-AR We will utilize two model systems for this study. The first is an organ culture system of human prostate tissue, a readily manipulable system that retains cell-cell interactions seen in the intact tissue. The second system is the spontaneously hypertensive rat, an animal model that displays elevated sympathetic activity with concomitant prostatic hyperplasia.

Project Title: THROMBOSPONDIN-1 IN PROSTATE DEVELOPMENT AND NEOPLASIA Principal Investigator & Institution: Crawford, Susan E.; Associate Professor; Pathology; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): Thrombospondin-1 (TSP-1) is a homotrimeric secreted glycoprotein that functions in a wide variety of biologic activities including embryonic development, tissue differentiation, neurite outgrowth, and responses to injury and inflammation. TSP-1 is also a potent inhibitor of angiogenesis, the growth of new blood vessels from the existing vasculature. Decreased TSP-1 expression contributes to the angiogenic environment that supports the growth of glioblastoma, fibrosarcomas and bladder cancer. Data is presented that show TSP-1 expression is down-regulated or lost in benign prostatic hyperplasia (BPH) and prostate cancer and identify TSP-1 as a key functional inhibitor of angiogenesis in the prostate. The normal and diseased prostate is exquisitely sensitive to changes in TSP-1 levels as TSP-1 null mice develop prostatic hyperplasia and TSP-1 expression increased after androgen ablation therapy in human prostate cancer specimens. Thus, we hypothesize that TSP- 1 plays a key role in the regulation of normal prostatic growth and that dysregulated TSP1 expression contributes to disease. To study the functions of TSP-1 in normal prostate growth and discern how dysregulated expression contributes to disease states, we plan to 1) characterize the prostate phenotype in the TSP-1 null mice, establishing a time course of disease development, and determine the underlying mechanism of the hyperplasia (i.e. increased proliferation or angiogenesis, decreased apoptosis or a combination of these), and 2) determine if androgen regulation of TSP-1 expression is critical to modulation of prostatic growth, using in vitro methods and the TSP-1 null

mouse model. Results from these experiments should establish the function of TSP-1 in prostatic growth regulation and determine how TSP-1 may be useful as a prognostic indicator or as a treatment for prostatic diseases. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: TRACKING UROGENITAL SINUS CELL PROGENY Principal Investigator & Institution: Sikes, Robert A.; Assistant Professor; Biological Sciences; University of Delaware Newark, De 19716 Timing: Fiscal Year 2002; Project Start 22-JUL-2002; Project End 30-JUN-2005 Summary: (provided by applicant): The cellular otigins of both benign and malignant prostate neoplasia remain elusive. Subtypes of benign prostatic hyperplasia (BPH) have been shown to respond differentially to androgen withdrawal, 5alpha-reductase inhibitors and alpha-adrenergic blockers. Likewise, malignant prostate cancer and its precursor, high-grade prostatic intra-epithelial neoplasia (PIN), have been shown to exhibit variable hormonal responsiveness with an unpredictable length of remission and time to recurrence. Much of the uncertainties reside in the lack of basic understanding of the origins of tumor epithelium, whether from basal/stem cells, neuroendocrine cells, luminal epithelial cells, or epithelial-mesenchymal interconversion. To gain further insight into the origin of prostate epithelium, efforts have been made to establish relevant tissue culture cell lines for comparative and correlative studies. These approaches have been faced with the criticism that passage of cells in vitro often results in genotypic and phenotypic "drift," which can no longer be used with confidence to define the nature of prostate cells from the diseased state. Moreover, normal prostatic epithelial cells, either immortalized with large T antigens or transfected with ras or myc oncoproteins, have dramatic alterations in phenotype and genotype when compared to prostatic epithelial cells that progress without such specific genetic context. Faced with these deficiencies, methods of analyzing directly clinical specimens using microdissection, high-throughput cDNA microarray and comparative genomic hybridization have been used to delineate the molecular profiling of normal and diseased tissues andcells. In the proposed study, we seek to define the molecular basis of the normal and diseased prostate gland, with special emphasis on cell-lineage relationships through profiling of genes that are associated with urogenital sinus (UGS) epithelium, stromal, ventral pad, {dorsal or ventral UGS}. The hypothesis to be tested is: Differential expression of urogenital sinus "core" genes can be found during neonatal, pubertal and adult prostate development. These marker genes should prove useful in defining the origin of prostate cells in a lobe-specific and defined relationship. Sex steroid administration could affect the developmental "fate" of prostate cells normally under rigid temporal and spatial control. The aims to be pursued in this proposal are: Aim 1 Gene expression profiles will be defined in discrete UGS components, Aim 2 Confirmation of cellular location of UGS core genes in developmental stage-specific prostate glands. Aim 3 Determine changes in the pattern of UGS ?core? genes following various epigenetic stress (estradiol+ testosterone tx., lobe-specific responses to castration). The overall objectives of this proposal are to define the origin of the normal prostate cells with specific emphasis on the primordial origin of these cells based on an understanding of fetal UGS architecture and developmental capacity.

Project Title: TRANSCRIPTOME ANALYSIS IN NORMAL AND NEOPLASTIC PROSTATE Principal Investigator & Institution: Nelson, Peter S.; Associate Professor; Fred Hutchinson Cancer Research Center Box 19024, 1100 Fairview Ave N Seattle, Wa 98109 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-OCT-2003 Summary: (adapted from the application) The prostate gland contributes to a significant portion of the disease burden involving American males due to the high prevalence and increasing incidence of benign prostatic hyperplasia (BPH) and prostate carcinoma in aging men. Prostate cancer now represents the second leading cause of cancer death in American men. The prevalence of BPH numbers in the tens of millions. Nonetheless, little is known about the molecular factors that contribute to the onset or progression of these diseases. A primary impediment for identifying relevant molecular factors has been the paucity of information regarding the mechanisms of normal prostate growth and differentiation. Few regulatory genes are known to be expressed specifically during prostate development or to be required for prostate function. One approach toward the identification of factors involved in prostate development involves the use of mouse models. The mouse has the significant advantage of having an extensive background of accumulated genetic knowledge. In addition, the mouse genetic program can be manipulated in the form of transgenic and gene deletion animals to provide insights for gene function. We hypothesize that the dysregulation of genes directing the normal development of the prostate gland influence the pathogenesis of prostate diseases including BPH and malignancy. The specific aims of this proposal are to: Aim 1. To establish a virtual and physical cDNA clone archive representing developing, mature, and diseased mouse prostate. Aim 2. To identify specific stromal and epithelial factors responsible for the directed development of mouse prostate. Aim 3. To analyze the expression profiles of prostatic tissues derived from Nkx3.1 and p27Kipl knockout mice and determine their genetic interactions. The accomplishment of these aims will provide a genomics-based resource that defines cell type specific gene expression profiles associated with stages of normal development and neoplastic prostate growth.

The center will build on a critical mass of urology investigators that comprise a well-established urology research program at the University of Michigan. Toward the O'Brien Center objective, five urology research projects have been assembled that reflect a wide range of investigation across various, different urological diseases. This broad spectrum of investigation is proposed to reflect the unique objective of the O'Brien Award mechanism, that being the advancement of urology research in general. The breadth of our proposed work thus spans from pediatric to adult urological diseases, and from basic science to clinical research. In Project 1, Dr. Jill Macoska will use cDNA microarray expertise, and a unique age-specific stromal and epithelial prostate model, to identify gene expression differences consequent to effects of aging on stromal-epithelial interaction. The findings will have implications for the pathophysiology of benign prostatic hyperplasia (BPH). In Project 2, Dr. John Park will use unique knockout models and cDNA microarrays to further characterize obstruction-induced COX-2 function in collecting duct cells, based on preliminary data implicating increased COX-2 expression in obstructive nephropathy. The findings may guide therapy development for obstructive nephropathy. In Project 3, Dr. Martin Sanda will use hybrid transgenic mouse models to characterize the role of FAS-mediated T cell death as a mediator of prostate-specific T cell tolerance. The findings will have implications for possible immune intervention in benign and malignant prostate diseases. In Project 4, Dr. John Wei and Dr. John Delancey will conduct clinical studies to identify intervention-specific, physiological/anatomic and racial determinants of urinary incontinence natural history and outcome. For this purpose they will use the Incontinence Symptom Index (ISI), a biometrically robust, validated, and broadly applicable instrument for measuring incontinence in multiple domains that they developed in preliminary studies. The findings should improve selection and evaluation of effective interventions for urinary incontinence. In Project 5, Dr. Mark Day will build on preliminary data implicating Rb and androgen receptor (AR) interaction in the regulation of prostate growth to characterize how Rb/E2F1 regulates AR trasncription and activity in vitro and in vivo. The findings have relevance to prostate growth and BPH. These 5 projects will be complemented by a Developmental Award Program that will further broaden the scope of this O'Brien Center to include new investigators in areas such as infertility and urological epidemiology, among others. Interaction between Projects will be facilitated by arl Administrative Core that will provide scientific oversight in the form of a multidisciplinary Center Advisory Board as well as biostatistical support in the form of

Project Title: URODYNAMIC AND MULTIETHNIC VARIABILITY OF MEN TREATED B* Principal Investigator & Institution: Kaplan, Steven A.; Professor of Urology, Vice Chair; Urology; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): Benign prostatic hyperplasia (BPH) is the most common affliction of men over the age of 50. Despite numerous innovations in therapy for BPH including medical and minimally invasive surgical therapies (MIST), transurethral resection of the prostate (TURP) remains the most effective. In part, the shortcomings of MIST have been the lack of uniform baseline study entry criteria, poor elucidation of baseline criteria aid in therapeutic success and paucity of long-term data. Furthermore, there have been no studies that have attempted to stratify response to therapy based on ethnic variability. Recent data suggests that there may be varying distribution of symptoms, objective diagnoses, and functional / morphologic aspects of the prostate among different ethnic groups. Do minimally invasive alternative surgical therapies result in alternating levels of success among different ethnic groups? The Prostate Center at the New York Presbyterian Medical Center evaluates and treats an ethnically diverse group of more than 1,000 men per year with lower urinary tract symptoms secondary to BPH. In addition it has access to and currently employs all FDA approved MIST procedures, including transurethral microwave thermotherapy, TUNA, interstitial laser, water induced thermotherapy, holmium laser prostatectomy and electrovaporization. We propose to examine the role of MISTs designed to treat BPH a multi - ethnic group. The goals of this clinical trial are to determine the urodynamic changes in bladder function and outlet obstruction in patients with BPH treated by MIST. Parameters to be analyzed include peak detrusor pressure during voiding, detrusor pressure during maximal flow, Shafer resistance curves, Abrams - Griffiths contractility index and detrusor contraction duration. These parameters will be assessed to determine prognostic significance and correlated with long term improvement as determined by changes in the American Urologic Association Symptom Score (AUASx), uroflow and post void residual urine. Specifically, this study aims to evaluate in a highly diverse multi - ethnic population: 1. Urodynamic contractility and resistance parameters which change significantly after MIST 2. Baseline urodynamic parameters which may predict improved outcome after MIST 3. The success of various types of MIST in treating BPH in African - American, Hispanic and Caucasian men.

Project Title: UROLOGICAL RESEARCH TRAINING GRANT Principal Investigator & Institution: Coffey, Donald S.; Professor; Urology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 01-MAY-1987; Project End 30-APR-2007 Summary: (provided by applicant): Genitourinary diseases cover abnormal development and growth, benign tumors and malignant cancers, abnormalities in kidney function and stone formation, infections, micturition, impotence and reproductive failure, as well as the neurological and endocrine control of the sex systems. This represents colossal medical problems requiring expertise in many areas of research. There is a critical shortage of trained research scientists in the field of urology. This research training program trains highly qualified young physician scientists for academic careers in urological research and develops young basic scientists (Ph.D. or M.D./Ph.D.) to pursue careers in urological research. Trainees function side-by-side in modern urology research laboratories occupied by 5 full-time Ph.D. basic scientists plus 6 M.D./Ph.D. and 10 M.D. clinical research investigators. These laboratories carry out major funded research programs in the physiology of the smooth muscle of the genitourinary tract, biochemical and physiological studies on benign prostatic hyperplasia, endocrine studies on male secondary sex characteristics, cell biology and structure, mechanisms of action of steroid hormones, genetic studies, neurotransmitter and receptor studies of genitoruinary tissues, reproductive physiology; and basic and clinical studies on cancer. Each trainee participates in a research training program that is customized for his/her particular needs and interests and includes courses in molecular biology, biostatistics, endocrinology, pathology and physiology. The six research trainees are comprised of three types: 1.) Postresident physician scientists - completed

residency training, spending an additional 1-2 years in research, 2.) M.D. Urological Research Fellows will spend 1 or more years in full time research, and 3.) Postdoctoral Research Fellows - Ph.D. or M.D./Ph.D., in full time research, who have already completed graduate training in a basic science discipline, plus 4.) Predoctoral Trainees, Ph.D. graduate program students carrying out thesis research in the urology labs who are not funded by this grant but who form part of the research-training environment. Each of these four components of our urological training program enriches and contributes to the success of each part. A multidisciplinary environment of graduate students, postdoctorals, postresidency, M.D.'s all doing research within the same environment has proven to be synergistic. The ability to understand the biology of the disease and to work on human pathological material with the application of precise molecular and pathological techniques that are now forthcoming provides a rich environment for future research leaders to study the major medical problems within the field of urology. Past successes of these laboratories in bridging clinical and basic research has produced a large number of scientists and physician scientists who are dedicated to solving urological diseases.

Project Title: ZINC TRANSPORT RELATIONSHIPS IN PROSTATE CANCER CELLS Principal Investigator & Institution: Franklin, Renty B.; Professor; Oral & Craniofacial Biol Scis; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2004; Project Start 01-AUG-1999; Project End 30-APR-2009 Summary: (provided by applicant): It is well established that prostate cancer (PCa), as contrasted with normal prostate or benign prostatic hyperplasia (BPH), is consistently characterized by dramatic decreases in citrate and zinc levels. Strong and compelling evidence exists that implicate a significant role of altered zinc accumulation in the regulation of citrate metabolism of prostate epithelial cells associated with the development and progression of prostate malignancy. Our broad objectives are to establish the mechanism and regulation of zinc accumulation in normal prostate cells; to determine the alterations that accounts for the loss of zinc accumulation associated with the pathogenesis and progression of malignancy; to establish mechanisms to restore zinc accumulation in malignant and pre-malignant prostate cells; to use this information in the development of new approaches to the diagnosis, treatment and perhaps prevention of prostate malignancy. Normal prostate glandular epithelial cells have the major function and capability of accumulating and secreting the highest levels of both citrate and zinc in the body. We recently established the important link between zinc and citrate; i.e., zinc inhibits (mitochondrial) m-aconitase activity and citrate oxidation of citrate-producing prostate epithelial cells. In PCa, prostate cells undergo a transformation from zinc-accumulating, citrate-producing sane cells to citrate oxidizing malignant cells, due to the lost ability to accumulate high zinc levels. This metabolic transformation occurs early in malignancy and is an apparent requirement for progression of the malignancy. Thus, the mechanism involved in the lost ability to accumulate zinc, which permits the alteration in citrate metabolism, is a key relationship in prostate malignancy. The specific aims of the proposal are: 1. To establish the mechanism by which ZIP1 facilitates the transport of zinc from plasma into the cell. 2. To determine the structure of the regulatory region of the ZIP1 gene that confers prolactin and testosterone regulation. 3. To establish that altered expression of ZIP1 alters the tumorigenicity of prostate cells (PC-3 and LNCaP). 4. To determine if

decreases expression of ZIP1 and decreased zinc accumulation are characteristics of malignant cells in prostate cancer. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

E-Journals: PubMed Central3 PubMed Central (PMC) is a digital archive of life sciences journal literature developed and managed by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM).4 Access to this growing archive of e-journals is free and unrestricted.5 To search, go to http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Pmc, and type “benign prostatic hyperplasia” (or synonyms) into the search box. This search gives you access to full-text articles. The following is a sample of items found for benign prostatic hyperplasia in the PubMed Central database: •

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with benign prostatic hyperplasia, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “benign prostatic hyperplasia” (or synonyms) into the search box, and click “Go.” The following is 3 4

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION HYPERPLASIA

AND

BENIGN

PROSTATIC

Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and benign prostatic hyperplasia.

Finding Nutrition Studies on Benign Prostatic Hyperplasia The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail: [email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “benign prostatic hyperplasia” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 4. HYPERPLASIA

PATENTS

ON

BENIGN

PROSTATIC

Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “benign prostatic hyperplasia” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on benign prostatic hyperplasia, we have not necessarily excluded non-medical patents in this bibliography.

Patents on Benign Prostatic Hyperplasia By performing a patent search focusing on benign prostatic hyperplasia, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent 8Adapted

descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an example of the type of information that you can expect to obtain from a patent search on benign prostatic hyperplasia: •

Alpha 1a adrenergic receptor antagonists Inventor(s): Bock; Mark G. (Hatfield, PA), Lagu; Bharat (Maywood, NJ), Newton; Randall C. (West Point, PA), Patane; Michael A. (Harleysville, PA) Assignee(s): Merck & Co., Inc (Rahway, NJ), Synaptic Pharmaceutical Corporation (Paramus, NJ) Patent Number: 6,376,503 Date filed: June 17, 1998 Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved. Excerpt(s): This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenoceptor antagonists. More particularly, the compounds of the present invention are useful for treating benign prostatic hyperplasia (BPH). Human adrenergic receptors are integral membrane proteins which have been classified into two broad classes, the alpha and the beta adrenergic receptors. Both types mediate the action of the peripheral sympathetic nervous system upon binding of catecholamines, norepinephrine and epinephrine. Norepinephrine is produced by adrenergic nerve endings, while epinephrine is produced by the adrenal medulla. The binding affinity of adrenergic receptors for these compounds forms one basis of the classification: alpha receptors bind norepinephrine more strongly than epinephrine and much more strongly than the synthetic compound isoproterenol. The binding affinity of these hormones is reversed for the beta receptors. In many tissues, the functional responses, such as smooth muscle contraction, induced by alpha receptor activation are opposed to responses induced by beta receptor binding.

Combination therapy for the prophylaxis and/or treatment of benign prostatic hyperplasia Inventor(s): Labrie; Fernand (Ste-Foy, CA) Assignee(s): Endorecherche, Inc. (CA) Patent Number: 6,423,698 Date filed: June 7, 1995 Abstract: A combination therapy for the prophylaxis and/or treatment of benign prostatic hyperplasia in susceptible warm-blooded animals which comprises administering a combination of two or more compounds selected from the group consisting of an inhibitor of 5.alpha.-reductase activity, an anti-estrogen, an inhibitor of aromatase activity, an inhibitor of 17.beta.-hydroxysteroid dehydrogenase activity and, in some cases, an anti-androgen and/or an LHRH agonist. Pharmaceutical compositions

154

Benign Prostatic Hyperplasia

useful for such treatment and pharmaceutical kits containing such compositions are disclosed. Excerpt(s): This invention relates to a method of prophylaxis and/or treatment of benign prostatic hyperplasia (BPH) in susceptible warm-blooded animals including man and in particular to a combination therapy involving administering a combination of drugs which inhibit sex steroid (androgens and estrogens) activity by blocking their formation and/or by blocking receptors where they act. The role of androgens in the development of benign prostatic hyperplasia in men is well documented (Wilson, N. Engl. J. Med. 317: 628-629, 1987). In fact, benign prostatic hyperplasia does not develop in the absence of the testes (referred to in Wendel et al., J. Urol. 108: 116-119, 1972). Blockade of testicular androgen secretion by surgical or medical (LHRH agonist) castration is known to decrease prostatic size (Auclair et al., Biochem. Biophys. Res. Commun. 76: 855-862, 1977; Auclair et al., Endocrinology 101: 1890-1893, 1977; Labrie et al., Int. J. Andrology, suppl. 2 (V.

Combination therapy for the treatment of benign prostatic hyperplasia Inventor(s): Broten; Theodore P. (Ambler, PA), Nichtberger; Steven A. (Gladwyne, PA), Siegl; Peter K. S. (Blue Bell, PA) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,410,554 Date filed: March 23, 1999 Abstract: This invention relates to combination therapy for the treatment of benign prostatic hyperplasia comprising an alpha-1a antagonist and an endothelin antagonist. More specifically, the use of a selective alpha-1a adrenergic receptor antagonist in combination with a subtype non-selective endothelin antagonist provides relief of lower urinary tract symptoms in patients with symptomatic prostatism or benign prostatic hyperplasia. This combination therapy improves lower urinary tract symptoms including increasing urine flow rate, decreasing residual urine volume and improving overall obstructive and irritative symptoms in patients with benign prostatic hyperplasia or symptomatic prostatism. Excerpt(s): The present invention provides combination therapy for the treatment of benign prostatic hyperplasia. More particularly, the combination comprises an alpha-1a adrenergic receptor antagonist with an endothelin antagonist, and optionally a 5areductase inhibitor, for relief of lower urinary tract symptoms in patients with symptomatic prostatism or benign prostatic hyperplasia. Benign prostatic hyperplasia, also known as benign prostatic hypertrophy or BPH, is an illness typically affecting men over fifty years of age, increasing in severity with increasing age. The symptoms of the condition include, but are not limited to, increased difficulty in urination and sexual dysfunction. These symptoms are induced by enlargement, or hyperplasia, of the

Patents 155

prostate gland. As the prostate increases in size, it impinges on free-flow of fluids through the male urethra. Concommitantly, the increased noradrenergic innervation of the enlarged prostate leads to an increased adrenergic tone of the bladder neck and urethra, further restricting the flow of urine through the urethra. Bladder outlet obstruction (BOO) in BPH patients results from a static component of increased prostatic mass which physically impinges on the urethra and a dynamic component of increased contractile tone of the prostatic-urethral smooth muscle. Standard treatment of BPH involves surgical or pharmacological intervention. Surgical intervention, either by removal of the prostate via radical prostatectomy or removing the prostatic adenoma via transurethral resection of the prostate alleviates both the static and dynamic components of BOO since the entire prostate or the majority of the prostatic smooth muscle is removed. Although these procedures result in the most marked improvement in symptoms, there is the possibility of mortality and morbidity since these are invasive surgical procedures. Many patients suffer incontinence and retrograde ejaculation as a consequence of these surgical procedures. Because of the chances for morbidity and mortality, these procedures are not optimum for patients with mild to moderate symptoms in a disease which is not life-threatening.

Dihydropyrimidines and uses thereof Inventor(s): Cui; Donghui (Newtown, PA), Davis; Margaret R. (Redmond, WA), Dunn; Michael (Cambridge, MA), Evans; Ben E. (Lansdale, PA), Kari; Hanumath P. (Hatfield, PA), Lagu; Bharat (Maywood, NJ), Nagarathnam; Dhanapalan (Bethany, CT), Vyas; Kamlesh P. (North Wales, PA), Zhang; Kanyin (San Diego, CA) Assignee(s): Synaptic Pharmaceutical Corporation (Paramus, NJ) Patent Number: 6,680,323 Date filed: June 4, 2001 Abstract: This invention is directed to dihydropyrimidines which are selective antagonists for human.alpha.sub.1a receptors. This invention is also related to uses of these compounds for relaxing lower urinary tract tissue, treating benign prostatic hyperplasia and for the treatment of any disease where the antagonism of the.alpha.sub.1a receptor may be useful. The invention further provides a pharmaceutical composition comprising a therapeutically effective amount of the abovedefined compounds and a pharmaceutically acceptable carrier. Excerpt(s): Throughout this application, various references are referred to within parentheses. Disclosures of these publications in their entireties are hereby incorporated by reference into this application to more fully describe the state of the art to which this invention pertains. Benign Prostatic Hyperplasia (BPH), also called Benign Prostatic Hypertrophy, is a progressive condition which is characterized by a nodular enlargement of prostatic tissue resulting in obstruction of the urethra. This results in increased frequency of urination, nocturia, a poor urine stream and hesitancy or delay in starting the urine flow. Chronic consequences of BPH can include hypertrophy of bladder smooth muscle, a decompensated bladder and an increased incidence of urinary tract infection. The specific biochemical, histological and pharmacological properties of the prostate adenoma leading to the bladder outlet obstruction are not yet known. However, the development of BPH is considered to be an inescapable phenomenon for the aging male population. BPH is observed in approximately 70% of males over the age of 70. Currently, in the United States, the method of choice for treating BPH is surgery

156

Benign Prostatic Hyperplasia

(Lepor, H., Urol. Clinics North Amer., 17, 651 (1990)). Over 400,000 prostatectomies are performed annually (data from 1986). A medicinal alternative to surgery is clearly very desirable. The limitations of surgery for treating BPH include the morbidity rate of an operative procedure in elderly men, persistence or recurrence of obstructive and irritative symptoms, as well as the significant cost of surgery.alpha.-Adrenergic receptors (McGrath, et. al. Med. Res. Rev., 9, 407-533, 1989) are specific neuroreceptor proteins located in the peripheral and central nervous systems on tissues and organs throughout the body. These receptors are important switches for controlling many physiological functions and, thus, represent important targets for drug development. In fact, many.alpha.-adrenergic drugs have been developed over the past 40 years. Examples include clonidine, phenoxybenzamine and prazosin (treatment of hypertension), naphazoline (nasal decongestant), and apraclonidine (treating glaucoma).alpha.-Adrenergic drugs can be broken down into two distinct classes: agonists (clonidine and naphazoline are agonists), which mimic the receptor activation properties of the endogenous neurotransmitter norepinephrine, and antagonists (phenoxybenzamine and prazosin are antagonists), which act to block the effects of norepinephrine. Many of these drugs are effective but also produce unwanted side effects (for example, clonidine produces dry mouth and sedation in addition to its antihypertensive effects).

Dual mode transurethral microwave warming apparatus Inventor(s): Carr; Kenneth L. (Harvard, MA), Regan; James F. (Waltham, MA) Assignee(s): Meridian Medical Systems, LLC (Ayer, MA) Patent Number: 6,424,869 Date filed: January 3, 2000 Abstract: A dual mode transurethral warming apparatus particularly adapted to treat benign prostatic hyperplasia includes a urethral catheter dimensioned for insertia through the urethra. The catheter includes an elongated flexible tube having a plurality of longitudinal lumens extending between the ends of the tube. A coaxial cable extends along one of the lumens to an antenna in the form of a multi-turn helical winding wound around the outside of the tube. A first connector connects one of the cable conductors to one end of the winding and a second connector connects the other cable conductor to the other end of the winding so that the antenna formed by the winding is larger in diameter than the cable, and all of the lumens are located within the winding. The cable is connected to a control and display unit which includes a transmitter which provides electromagnetic energy via the cable to the antenna so that the antenna generates an electromagnetic field sufficient to treat tissue adjacent the antenna. The same antenna also detects thermal energy emitted by the tissue thereby developing an electrical signal which is fed via the cable to a receiver in the form of a radiometer in the control and display unit. The cable is connected to the transmitter and receiver by way of a diplexer which separates the transmitter and receiver signal frequencies allowing the use of the common coaxial cable and antenna for both heating the tissue and sensing the actual temperature of the tissue. Preferably, the catheter includes an inflatable balloon at the distal end of the tube, the balloon being inflated by flowing an inflation fluid to the balloon via one of the lumens in the tube. Other working lumens may be included in the tube for providing drainage and for coolant circulation to cool the exterior surfaces of the catheter.

Excerpt(s): This application relates to transurethral hypothermia apparatus. It relates more particularly to a dual mode (i.e heating and sensing) transurethral microwave warming apparatus. It is well known that heat can be used to reduce an enlarged prostate. Benign prostatic hyperplasia (BPH) is a common disease among aging men that may lead to several complications such as urinary tract infection, acute urinary retention or uremia. In the U.S. alone, there are approximately 400,000 transurethral resection procedures performed each year involving general anesthesia and hospitalization to treat the above problem. Many patients are poor surgical risks due to age and possible co-existing health problems. Microwave hyperthermia appears to be a practical alternative to transurethral resection for the prostate, the usual surgical procedure. Microwave transurethral hyperthermia involves insertion of a small catheter, including a microwave antenna, into the bladder via the urethra. This procedure can be performed in an outpatient basis without the need for general anesthesia. Web site: http://www.delphion.com/details?pn=US06424869__ •

Forms of free prostate-specific antigen (PSA) and their association with prostate tissues from prostate peripheral zone and transition zone Inventor(s): Mikolajczyk; Stephen D. (San Diego, CA), Rittenhouse; Harry G. (Del Mar, CA), Slawin; Kevin (Houston, TX), Wang; Tang Jang (Poway, CA), Wolfert; Robert L. (San Diego, CA) Assignee(s): Baylor College of Medicine (Houston, TX), Hybritech Incorporated (Fullerton, CA) Patent Number: 6,423,503 Date filed: April 30, 1999 Abstract: A method of distinguishing prostate cancer from benign prostatic hyperplasia (BPH) is provided. The mathematical combination or ratio of proPSA and BPSA serum or tissue markers may be used for distinguishing benign prostatic hyperplasia (BPH) from prostate cancer. It is the discovery of the present invention that BPSA is preferentially elevated in transition zone prostate tissue whereas pPSA is elevated in the peripheral zone of prostate tissue. A kit for aiding in distinguishing BPH from prostate cancer is also provided. Excerpt(s): The invention relates generally to prostate-specific antigen (PSA) and specifically to different forms of PSA and their association with prostate cancer and benign prostate disease. Throughout this application, various references are referred to within parentheses. Disclosures of these publications in their entireties are hereby incorporated by reference into this application to more fully describe the state of the art to which this invention pertains. Full bibliographic citation for these references may be found at the end of this application, preceding the claims. The measurement of serum PSA is a widely used marker for the early detection of human prostate cancer (1-3). Elevated levels of PSA in the blood are symptomatic of prostate disease, which is primarily manifested as either benign prostate hyperplasia (BPH) or prostate cancer (PCa). However, in the range 4-10 ng PSA per ml of serum it is difficult to distinguish BPH from PCa without additional tests such as digital rectal exam and prostate needle biopsy.

Method of constructing a microwave antenna Inventor(s): Arndt; G. Dickey (Friendswood, TX), Carl; James (Houston, TX), Ngo; Phong (Friendswood, TX) Assignee(s): The United States of America as represented by the Administrator of the (Washington, DC) Patent Number: 6,512,956 Date filed: December 18, 2000 Abstract: A method, simulation, and apparatus are provided that are highly suitable for treatment of benign prostatic hyperplasia (BPH). A catheter is disclosed that includes a small diameter disk loaded monopole antenna surrounded by fusion material having a high heat of fusion and a melting point preferably at or near body temperature. Microwaves from the antenna heat prostatic tissue to promote necrosing of the prostatic tissue that relieves the pressure of the prostatic tissue against the urethra as the body

160

Benign Prostatic Hyperplasia

reabsorbs the necrosed or dead tissue. The fusion material keeps the urethra cool by means of the heat of fusion of the fusion material. This prevents damage to the urethra while the prostatic tissue is necrosed. A computer simulation is provided that can be used to predict the resulting temperature profile produced in the prostatic tissue. By changing the various control features of the catheter and method of applying microwave energy a temperature profile can be predicted and produced that is similar to the temperature profile desired for the particular patient. Excerpt(s): The present invention relates to apparatus, methods, and computer simulations highly suitable for treatment of benign prostatic hyperplasia (BPH) and, more particularly, to a unique catheter for microwave treatment of BPH to necrose prostatic tissue while protecting urethral tissue and computer simulations relating to the same. Benign prostatic hypertrophy or hyperplasia (BPH) is one of the most common medical problems experienced by men over 50 years old. Urinary tract obstruction due to prostatic hyperplasia has been recognized since the earliest days of medicine. Hyperplastic enlargement of the prostate gland, or enlargement due to abnormal but benign multiplication of the cells thereof, often leads to compression of the urethra thereby resulting in obstruction of the urinary tract. Common symptoms that develop from this condition may include more frequent urination, decrease in urinary flow, nocturia, pain, and discomfort. The incidence of BPH in men over 50 years of age is approximately 50 percent and increases to over 75 percent in men over 80 years of age. Symptoms of urinary obstruction occur most frequently between the ages of 65 and 70 when approximately 65 percent of men in the age group have prostatic enlargement. When treatment by drug therapy is not sufficiently effective, surgical procedures for treating BPH are available but have potential side effects. General surgical risks apply such as anesthesia related morbidity, hemorrhage, coagulopathies, pulmonary emboli, electrolyte imbalance, and the like. Other problems that may occur from surgical correction include cardiac complications, bladder perforation, incontinence, infection, urethral or bladder neck stricture, retention of prostatic chips, and infertility. Due to the problems of surgery, many or even most patients delay treatment. However, the delay of treatment may lead to other complications including obstructive lesion in the prostate, chronic infection, and the like. Therefore it is unquestionable that a need exists for improved surgical or non-surgical methods for treating BPH. Web site: http://www.delphion.com/details?pn=US06512956__ •

Method of treating androgen-dependent disorders Inventor(s): Bond; Richard W. (Union, NJ), Pachter; Jonathan A. (Maplewood, NJ), Wang; Lynn (Fanwood, NJ) Assignee(s): Schering Corporation (Kenilworth, NJ) Patent Number: 6,710,037 Date filed: May 1, 2002 Abstract: Novel methods of treating subjects afflicted with an androgen-dependent disorder, such as prostate cancer and benign prostatic hyperplasia are disclosed. Specifically, methods of treating androgen-dependent disorders by introducing a polypeptide or a polynucleotide encoding the polypeptide, which enhances inactivation of active androgens, are described. Excerpt(s): All references cited herein are incorporated in their entirety by reference. The present invention relates to methods of using polypeptides or polynucleotides that

Patents 161

encode polypeptides which enhance inactivation of active androgens for the treatment of androgen-dependent disorders. Specifically, the present invention relates to methods of treating conditions wherein androgen activity is implicated such as prostate cancer, benign prostatic hyperplasia and other androgen-dependent disorders such as androgenic alopecia. An androgen-dependent disorder refers to any disorder that can benefit from a decrease in androgen stimulation and includes pathological conditions that depend on androgen stimulation. An androgen-dependent disorder can result from an excessive accumulation of testosterone or other androgenic hormone; increased sensitivity of androgen receptors to androgen; or an increase in androgen-stimulated transcription. Examples of androgen-dependent disorders include prostate cancer, benign prostatic hyperplasia, acne vulgaris, seborrhea, female hirsutism, androgenic alopecia (which includes female and male pattern baldness), and polycystic ovary syndrome. Early attempts to provide a chemotherapeutic agent to counter the undesirable results of androgen-dependent disorders resulted in the discovery of several steroidal antiandrogens having undesirable hormonal activities of their own. The estrogens, for example, not only counteract the effect of the androgens but have a feminizing effect as well. Non-steroidal antiandrogens have also been developed, for example, 4'-nitro-3'-trifluoromethyl-isobutyranilide. See Neri et al., "A Biological Profile of a Nonsteroidal Antiandrogen, SCH 13521 (4'-Nitro-3'Trifluoromethylisobutyranilide)", Endocrinology, 91(2):427-437 (1972). Unfortunately, even though these products are largely devoid of direct hormonal stimulatory effects, they compete with all natural androgens for receptor sites. Hence these products have a tendency to feminize a male host or the male fetus of a female host and/or initiate feedback effects that cause hyperstimulation of the testes with increased androgen production.

Method of treating benign prostatic hyperplasia and other benign prostate conditions Inventor(s): Parks; L. Dean (2420 SE. 15th St., Ocala, FL 34471) Assignee(s): none reported Patent Number: 6,733,779 Date filed: September 17, 2001 Abstract: Methods of treatment of benign prostatic hyperplasia and reduction of the level of the prostate specific antigen (PSA) of benign prostate conditions are disclosed. The treatment method includes an initial treatment of patients with orally administration of an initial dosage of about 40 mg 13 cis-retinoic acid daily for a period from about ten days to about twenty days, and followed by a sustaining treatment of the patients with orally administration of a sustaining dosage of about 40 mg 13 cis-retinoic acid about every five to seven days in a sustaining period. Excerpt(s): The present invention relates to methods for treating benign prostate hyperplasia and reducing the level of prostate specific antigen of benign prostate conditions. More specifically, the methods utilize 13 cis-retinoic acid to effectively treat benign prostate hyperplasia, and to reduce the level of prostate specific antigen of the patients with benign prostate conditions. The three most common prostate health problems facing men and their families today are benign prostatic hyperplasia (BPH), prostate cancer, and prostatitis. Each of these conditions affects the prostate differently. Benign prostate hyperplasia is the most common benign neoplasm (non cancerous enlargement of the prostate gland) in men, and has a high prevalence that increases with

162

Benign Prostatic Hyperplasia

age. The increase in size of the prostate inside its capsule exerts pressure on the urethra, which passes through the capsule, resulting in obstruction to urine flow. Half of all men have BPH identifiable histologically at age 60 years, and by 85 years the prevalence is about 90%. In the United States about 25% of men will be treated for BPH by age 80, and over 300,000 surgical procedures are performed each year for BPH (mostly transurethral resection of the prostate, TURP). This makes TURP the second most common surgical procedure, second only to cataract surgery--at a cost estimated at $2 billion per year. Experts do not yet know what causes BPH, but the condition may be related to the hormone testosterone and its relationship to other hormones that change during the aging process. There are a number of treatment options for BPH. These include watchful waiting, medical therapy such as alpha blocker therapy and finasteride therapy, balloon dilatation and various surgical procedures such as transurethral incision of the prostate (TUIP), transurethral resection of the prostate (TURP), and open prostatectomy. Few treatments are without any adverse consequences, and this is particularly so with treatments with BPH, where there is a delicate balancing act between the benefits and demerits of the treatments available. The adverse events following treatment for BPH include impotence (for various surgical procedures ranging from about 4% to 40%, the incidence of impotence is also increased after some medical treatments), incontinence (stress incontinence about 3% after surgery, with total urinary incontinence approaching 1%), and the need for re-treatment. Combined analysis of published data estimated that the mean probability for perioperative mortality (death within 90 days of a procedure) was 1.5% for TURP. For open surgery it was 2.4% and for balloon dilation it was 3.5%. Web site: http://www.delphion.com/details?pn=US06733779__ •

Use of.alpha.1C specific compounds to treat benign prostatic hyperplasia Inventor(s): Branchek; Theresa A. (Teaneck, NJ), Chiu; George (Bridgewater, NJ), Forray; Carlos C. (Paramus, NJ), Gluchowski; Charles (Danville, CA), Hartig; Paul R. (Pennington, NJ), Wetzel; John M. (Elmwood Park, NJ) Assignee(s): Synaptic Pharmaceutical Corporation (Paramus, NJ) Patent Number: 6,602,888 Date filed: November 22, 1999 Abstract: A method of treating benign prostatic hyperplasia in a subject which comprises administering to the subject a therapeutically effective amount of a compound which binds to a human.alpha.sub.1C adrenergic receptor with a binding affinity greater than ten-fold higher than the binding affinity with which the compound binds to a human.alpha.sub.1A adrenergic receptor, a human.alpha.sub.1B adrenergic receptor, and a human histamine H.sub.1 receptor, and, binds to a human.alpha.sub.2 adrenergic receptor with a binding affinity which is greater than ten-fold lower than the binding affinity with which the compound binds to such.alpha.sub.1C adrenergic receptor. Compounds meeting these criteria are provided. Excerpt(s): Benign Prostatic Hyperplasia (BPH), also called Benign Prostatic Hypertrophy, is a progressive condition which is characterized by a nodular enlargement of prostatic tissue resulting in obstruction of the urethra. This results in increased frequency of urination, nocturia, a poor urine stream and hesitancy or delay in starting the urine flow. Chronic consequences of BPH can include hypertrophy of bladder smooth muscle, a decompensated bladder and an increased incidence of urinary tract infection. The specific biochemical, histological and pharmacological properties of the prostate adenoma leading to the bladder outlet obstruction are not yet known. However, the development of BPH is considered to be an inescapable phenomenon for the aging male population. BPH is observed in approximately 70% of males over the age of 70. Currently, in the United States, the method of choice for treating BPH is surgery (Lepor, H. Urol. Clinics North Amer., 17, 651 (1990)). Over 400,000 prostatectomies are performed annually (data from 1986). A medicinal alternative to surgery is clearly very desirable. The limitations of surgery for treating BPH include the morbidity rate of an operative procedure in elderly men, persistence or recurrence of obstructive and irritative symptoms, as well as the significant cost of surgery.alpha.-Adrenergic receptors are specific neuroreceptor proteins located in the peripheral and central nervous systems on tissues throughout the body. These receptors are important switches for controlling many physiological functions and, thus, represent important targets for drug development. In fact, many.alpha.-adrenergic drugs have been developed over the past 40 years. Examples include clonidine, phenoxybenzamine and prazosin (treatment of hypertension), naphazoline (nasal decongestant), and apraclonidine (treating glaucoma).alpha.-Adrenergic drugs can be broken down into two distinct classes: agonists (clonidine and naphazoline are agonists), which mimic the

164

Benign Prostatic Hyperplasia

receptor activation properties of the endogenous neurotransmitter norepinephrine, and antagonists (phenoxybenzamine and prazosin are antagonists), which act to block the effects of norepinephrine. Many of these drugs are effective but also produce unwanted side effects (for example, clonidine produces dry mouth and sedation in addition to its antihypertensive effects). During the past 15 years a more precise understanding of.alpha.-adrenergic receptors and their drugs has evolved through increased scientific scrutiny. Prior to 1977, only one.alpha.-adrenergic receptor was known to exist. Between 1977 and 1988, it was accepted by the scientific community that at least two.alpha.adrenergic receptors--.alpha.sub.1 and.alpha.sub.2 --existed in the central and peripheral nervous systems. Since 1988, new techniques in molecular biology have led to the identification of at least six.alpha.-adrenergic receptors which exist throughout the central and peripheral nervous systems:.alpha.sub.1A,.alpha.sub.1B,.alpha.sub.1C,.alpha.sub.2A,.alpha.sub.2B and.alpha.sub.2C (Bylund, D. B., FASEB J., 6, 832 (1992)). It is not known precisely which physiological responses in the body are controlled by each of these receptors. In addition, many.alpha.-adrenergic drugs that were developed before 1992 are not selective for any particular.alpha.-adrenergic receptor. Many of these drugs produce untoward side effects which may be attributed to their poor.alpha.-adrenergic receptor selectivity. Web site: http://www.delphion.com/details?pn=US06602888__

Apparatus and method for the treatment of benign prostatic hyperplasia Inventor(s): Chornenky, Victor I.; (Minnetonka, MN), Jaafar, Ali; (Eden Prairie, MN) Correspondence: Ali Jaafar; 11600 Landing Road; Eden Prairie; MN; 55347; US Patent Application Number: 20040059389 Date filed: September 23, 2003 Abstract: An apparatus and method for treatment of benign prostatic hyperplasia is disclosed wherein the apparatus includes an applicator having a probe having proximal and distal probe sections wherein the proximal and distal probe sections each define an axis and wherein the axes are not collinear. Excerpt(s): The present application claims priority to U.S. Provisional Application No. 60/412,705 entitled "Apparatus and method for treatment of benign prostatic hyperplasia by electroporation", which was filed Sep. 23, 2002. This application also claims priority to U.S. patent application Ser. No. 10/217,749 entitled "Apparatus and method for treatment of benign prostatic hyperplasia by electroporation", which was filed Aug. 13, 2002 (U.S. Patent Application Publication 2003/0060856, published Mar. 27, 2003). The present invention relates generally to methods and apparatus for the electroporation of tissues and more specifically to such methods and apparatus for the treatment of benign prostatic hyperplasia. The biophysical phenomenon known as electroporation refers to the use of electric field pulses to induce microscopic pores-"electropores"--in the lipid cell membranes. Depending on the parameters of the electric pulses, an electroporated cell can survive the pulsing or die. The cause of death of an electroporated cell is believed to be a chemical imbalance in the cell, resulting from the fluid communication with the extra-cellular environment through the pores. For a given cell size, geometry, and orientation, the number of electropores--and their size--created in the cell by the applied electric field pulses depends on both the amplitude E of the electric field pulses and the duration t of the pulses. That is, for a given pulse duration t, no pores will be induced in the cell until the amplitude E reaches a certain lower limit. This limit is different for different cells, particularly, for cells of different sizes. The smaller the size of a cell, the higher the electric field required to induce pores and thus the higher the lower limit is. Above the lower amplitude E limit the number of pores and their effective diameter increases proportionally with both increasing field amplitude E and pulse duration t. Electroporation is observed for pulse durations in the range from tens of microseconds to hundreds of milliseconds. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Benign Prostatic Hyperplasia

Apparatus and method for treatment of benign prostatic hyperplasia Inventor(s): Chornenky, Victor; (Minnetonka, MN), Jaafar, Ali; (Eden Prairie, MN) Correspondence: Briggs And Morgan, P.A.; 2400 Ids Center; Minneapolis; MN; 55402; US Patent Application Number: 20030060856 Date filed: August 13, 2002 Abstract: An apparatus and a method for treatment of benign prostatic hyperplasia are disclosed. The apparatus includes an applicator piece carrying a set of electrodes shaped and positioned to create a substantial electric field in the volume of hyperplasia and a pulse generator adapted for delivery of electrical pulses above the upper electroporation limit for the neoplastic cells. The amplitude, duration and number of the electrical pulses are generally selected to cause necrosis of a significant fraction of the volume of benign prostatic hyperplasia. The apparatus may include a high frequency system for heating the prostatic tissue and a cooling system for cooling the urethra. The combined action of heating and cooling may increase the temperature of the prostate cells to 45.degree. C. to 55.degree. C., while keeping the urinary tract at a temperature 15.degree. C. to 20.degree. C. This temperature distribution can increase the selectivity of the treatment by increasing susceptibility of the neoplastic cells to the electroporation treatment and decreasing it for the normal urethral tissues. Excerpt(s): The present application claims priority to U.S. Provisional Application No. 60/311,792 entitled "Apparatus and method for treatment of benign prostatic hyperplasia by electroporation", which was filed Aug. 13, 2001. This application also claims priority to U.S. Provisional Application No. 60/325,994 entitled "Apparatus and method for treatment of benign prostatic hyperplasia by electroporation", which was filed Oct. 1, 2001. The present invention relates generally to the therapeutic treatment of tissues and more particularly, to an apparatus and method for therapeutic treatment of benign prostatic hyperplasia. Biophysical phenomenon "electroporation" (EP) refers to the use of electric field pulses to induce microscopic aquatic pores--"electropores"--in the lipid cell membranes. Depending on the parameters of the electric pulses, electroporated cell can survive the pulsing or die. The cause of death of an electroporated cell is believed to be a chemical imbalance in the cell, resulted from the fluid communication with the extra cellular environment through the pores. The number and size of electropores depend on both, the amplitude of electric field pulse E and the pulse duration t. Electroporation is observed for pulse durations in the range from tens of microseconds to hundreds of milliseconds. For a given duration of a pulse and bellow a certain limit of the electric field amplitude, no pores are induced at all. This limit is different for different cells, particularly, for cells of different sizes. The smaller the size of a cell, the higher the electric field required to induce pores and thus the higher the limit is. Above the lower limit the number of pores and their effective diameter increases proportionally with both the amplitude E and duration t.

The compound of this application has an antiandrogen action and is useful in preventing or treating prostatic cancer, benign prostatic hyperplasia and the like diseases. Excerpt(s): This is a divisional of application Ser. No. 09/787,672 filed Mar. 21, 2001, which is a Continuation Application of PCT Application No. PCT/JP99/05149 filed Sep. 21, 1999; the above noted prior applications are all hereby incorporated by reference. This invention relates to novel cyanophenyl derivatives useful as medicaments, particularly as an anti-androgen, and salts and pharmaceutical compositions thereof. Androgen as a steroid hormone is secreted from testis and adrenal cortex and induces male sex hormone actions. Androgen, when incorporated into target cells, acts upon an androgen receptor and the receptor to which androgen binds forms a dimer. Subsequently, this dimer binds to an androgen-response-element on DNA to accelerate synthesis of mRNA and to thereby induce proteins which control the androgen actions, thus expressing various actions within living organism (Prostate Suppl., 6, 1996, 45-51, Trends in Endocrinology and Metabolism, 1998, 9 (8), 317-324).

Identifying drugs for and diagnosis of benign prostatic hyperplasia using gene expression profiles Inventor(s): Getzenberg, Robert H.; (Pittsburgh, PA), Kulkarni, Prakash; (Gaithersburg, MD), Munger, William E.; (Gaithersburg, MD), Waga, Iwao; (Yokohama, JP), Yamamoto, Jun; (Yokohama, JP) Correspondence: Morgan Lewis & Bockius Llp; 1111 Pennsylvania Avenue NW; Washington; DC; 20004; US Patent Application Number: 20030134280 Date filed: September 24, 2001 Abstract: The present invention is based on the elucidation of the global changes in gene expression in prostate tissue isolated from patients exhibiting different clinical states of prostate hyperplasia as compared to normal prostate tissue as well as the identification of individual genes that are differentially expressed in diseased prostate tissue. Excerpt(s): This application claims priority of U.S. Provisional Application No. 60/223,323, filed Aug. 7, 2000, and U.S. application Ser. No. 09/873,319, filed Jun. 5, 2001, which are herein incorporated by reference in their entirety. Benign Prostatic Hyperplasia (BPH) is the most common benign tumor in men aged >60 years. It is estimated that one in four men living to the age of 80 will require treatment for this disease. BPH is usually noted clinically after the age of 50, the incidence increasing with age, but as many as two thirds of men between the ages of 40 and 49 demonstrate histological evidence of the disease. The anatomic location of the prostate at the bladder neck enveloping the urethra plays an important role in the pathology of BPH, including bladder outlet obstruction. Two prostate components are thought to play a role in bladder outlet obstruction. The first is the relative increased prostate tissue mass. The second component is the prostatic smooth muscle tone.

Immunological test and diagnostic kit for prostate adenocarcinoma Inventor(s): Charrier, Jean-Philippe; (Ecully, FR) Correspondence: James C Lydon; Suite 100; 100 Daingerfield Road; Alexandria; VA; 22314; US Patent Application Number: 20040038321 Date filed: December 12, 2002 Abstract: This invention concerns a test method for the purposes of diagnosis, prognosis or therapeutic monitoring in male patients with adenocarcinoma of the prostate or benign prostatic hyperplasia, which does not require a biopsy of prostate tissue, and which exploits the combination of at least one tissue-specific marker and at least one marker for inflammation in order to arrive at a diagnosis.The invention also concerns a process using such a method, an immunological test to implement such a process, and a diagnostic kit.The invention is applied to the diagnosis of adenocarcinoma of the prostate and benign prostatic hyperplasia. Excerpt(s): This invention concerns a screening or diagnostic method for the detection of prostate cancer (i.e. adenocarcinoma of the prostate, usually abbreviated to PCa) and benign prostatic hyperplasia (abbreviated to BPH) in patients, a method which does not involve the taking of a biopsy. More generally, the invention concerns a test method for the purposes of diagnosis, prognosis or therapeutic monitoring of cancer in human patients. By diagnosis, it is meant that the marker reveals whether or not the patient is suffering from a certain disease. By prognosis, it is meant that the marker reveals the seriousness of the disease. The prognosis can guide the therapeutic strategy. Finally, by therapeutic monitoring, it is meant that the marker can be used to follow the efficacy of treatment. If the chosen treatment strategy is failing (as revealed by the marker), the patient can be offered an alternative. Prostate-specific antigen (PSA) is synthesized by epithelial cells of the human prostate gland, probably in the form of an inactive zymogen (Lundwall et al. FEBS LeH 1987) and is secreted in the seminal fluid in an active form (Lilja, J. Clin Invest 1985). The biological activity of PSA in seminal fluid consists of controlled proteolysis of the most abundant proteins secreted by the seminal vesicles (Lilja, J. Clin Invest 1985; Lilja et al. J. Clin Invest 1987; Mc Gee et al. Biol. Reprod. 1988). Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Insulin-like growth factor system and cancer Inventor(s): Diamandi, Anastasia; (Toronto, CA), Khosravi, M. Javad; (Toronto, CA), Mistry, Jehangir; (League City, TX) Correspondence: Haynes And Boone, Llp; 901 Main Street, Suite 3100; Dallas; TX; 75202; US Patent Application Number: 20030017513 Date filed: March 7, 2002 Abstract: Method of monitoring or diagnosing disease conditions, including disease of the prostrate, that involve measuring a combination of tumour markers and at least one component of the IGF axis. The invention is exemplified with prostate cancer and benign prostatic hyperplasia, the tumor marker prostate specific antigen, and the insulin-like growth factors and their binding proteins.

Patents 173

Excerpt(s): This invention relates to the measurement of the IGF-axis component levels and tumor marker levels for use in assessing cancer risk and/or progression and/or distinguishing between cancer and other non-malignant disorders. The invention is exemplified with prostate cancer (CaP) and benign prostatic hyperplasia (BHP), the tumor marker prostate specific antigen (PSA), and the insulin-like growth factors (IGF) and their binding proteins (IGFBP). Specifically, IGF-I, intact IGFBP-3, fragment IGFBP3, total IGFBP-3, free PSA and total PSA were assayed and certain permutations of these measurements were found to present improved diagnostic indicators. The method is predicted to have general applicability to other IGF-system related cancers. The insulinlike growth factor (IGF) family of high affinity IGF binding proteins (IGFBP-1-6) (14) has recently evolved to a superfamily status in order to accommodate a related group of newly discovered low affinity IGFBPs called the IGFBP related proteins (5). The conventional view of IGFBPs as the sole regulators of IGF bioavailability and bioactivity has also evolved to include the IGF-independent properties of IGFBPs (6, 7). IGFBPs, particularly IGFBP-3, have been recently identified as potent apoptotic agents (8-12), presumably mediating the effects of cellular growth suppressing mechanisms (8, 11, 12). The emerging new concept appears to similarly broaden the pathophysiological roles of the IGF peptides to include their potential involvement in regulation of the IGFBPs' bioactivity (8). In this ever-expanding maze of reciprocal molecular interactions, posttranslational modification by selective proteolysis is rapidly gaining acceptance as the key modulator of the IGF/IGFBP system and a major determinant of their effects on cellular growth and metabolism (13, 14). Insulin-like growth factors (IGF-I and -II) are mitogenic and anti-apoptotic agents produced primarily by the liver and locally by a wide variety of tissues. IGFs circulate mostly complexed with IGFBP-3, which in association with the acid-labile subunit (ALS) forms an approximately 150 kD ternary protein complex (1-4). Under normal conditions, nearly all of the circulating IGFs remain ternary complexed (75-80%), and smaller proportions (20-25%) are associated with the low molecular weight IGFBPs (IGFBP-1, IGFBP-2, IGFBP-4, IGFBP-5, and IGFBP-6) or exist in the free form (1-4).

Benign Prostatic Hyperplasia

Excerpt(s): This invention relates to prostate cancer, and more particularly to methods and compositions for inhibiting the proliferation of prostate cancer cells. The prostate gland is located between the bladder and the rectum and wraps around the urethra. The prostate is composed of glandular tissue that produces a milky fluid and smooth muscles that contract during sex and squeeze this fluid into the urethra where it mixes with other fluid and sperm to form semen. The prostate gland converts testosterone to a more powerful male hormone, dihydrotestosterone, which affects the size of the gland and plays an important role in prostate cancer. Prostate cancer is a malignant tumor that arises in the prostate gland and can eventually spread through the blood and lymph fluid to other organs, bones, and tissues. Prostate cancer is the most commonly diagnosed cancer in the U.S., and it is the second leading cause of cancer death in American men after non-melanoma skin cancer. Although prostate cancer is just as common in Japan as in the United States, death rates from prostate cancer are significantly lower in Japan. It is unlikely that these differences are all genetic, because Japanese men who migrate to the United States die of prostate cancer with increasing frequency as a function of the number of years they reside in the United States. It is possible that this paradox could be explained, at least in part, by dietary factors. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Methods and compositions for the treatment of benign prostatic hypertrophy Inventor(s): Randhava, Sarabjit; (Evanston, IL), Randhava, Sikander; (Evanston, IL), Randhava, Surjit; (Evanston, IL) Correspondence: Katten Muchin Zavis Rosenman; Attention: Patent Administrator; Suite 1600; 525 West Monroe Street; Chicago; IL; 60661-3693; US Patent Application Number: 20030096009 Date filed: October 23, 2002 Abstract: This invention relates to a composition for use in treating benign prostatic hyperplasia including a saw palmetto extract provided in an oral controlled release formulation which allows release of active ingredients in the intestinal tract and which allows the maintenance of therapeutic levels of active agents in the bloodstream for prolonged periods of time. This invention also relates to a composition for improving the efficacy of a saw palmetto extract, a method of treating benign prostatic hypertrophy, and a method of improving the efficacy of a saw palmetto extract treatment. Excerpt(s): This invention relates to a composition for use in treating benign prostatic hyperplasia, which comprises saw palmetto extract contained in a controlled delivery system. The composition is preferably administered orally, uses a controlled delivery system to provide a targeted, extended release of the saw palmetto extract into the bloodstream. Many men over the age of fifty commonly experience a condition known as benign prostatic hyperplasia, or BPH. BPH affects as much as 40% of the male population over the age of seventy. The condition is commonly recognized as a swelling of the prostate gland. This problem gradually manifests itself in the form of a) frequent urination, b) small discharge volumes and "dribbling", and c) unsatisfying bladder evacuations. Waking up to urinate once or more each night is a typical sign of this problem. BPH is a chronic condition that tends to gradually worsen with age. The increased incidence of BPH in older men may be due to the fact that as men age, testosterone levels tend to decline and estrogen levels rise. In the process, testosterone metabolism takes a different pathway, and testosterone is converted to

Patents 175

dihydrotestosterone (DHT), a potent male hormone that causes prostate enlargement. The actions of DHT can be limited by restricting the enzymatic production of DHT from testosterone and/or blocking the direct pharmacological action of DHT at the receptor level. Current therapies for BPH focus on limiting the actions of DHT, and include: pharmaceutical intervention with 5-.alpha.-reductase inhibitors such as finasteride (Proscar.RTM.); pharmacological intervention with.alpha.-adrenergic blockers, such as terazosin HCl (Hytrin.RTM.), and doxazosin mesylate (Cardura.RTM.); prostatectomy; and administration of saw palmetto extract.

Novel antibody, immunoassay and method for prostate cancer detection Inventor(s): Lilja, Hans; (Skanor, SE), Lovgren, Timo; (Turku, FI), Niemela, Pauliina; (Turku, FI), Pettersson, Kim; (Turku, FI) Correspondence: Rothwell, Figg, Ernst & Manbeck, P.C.; 1425 K Street, N.W.; Suite 800; Washington; DC; 20005; US Patent Application Number: 20040101914 Date filed: July 21, 2003 Abstract: This invention concerns an antibody wherein said antibody does bind with high affinity to human single-chain intact, i.e. not internally cleaved, mature and/or zymogen forms of prostate specific antigen (SCINT PSA). The antibody, obtainable through immunization with an uncleaved form of PSA and selected by its differential reactivity with the intact and internally cleaved forms, does not bind to a nicked PSA (PSA-N), wherein said PSA-N has been formed by internal peptide bond cleavage(s) of SCINT PSA resulting in two-chain or multi-chain PSA. This invention further concerns an immunoassay and a method for differentiating patients with cancer of the prostate (PCa) from patients with benign prostatic hyperplasia (BPH) and/or healthy male subjects without PCa, patients with aggressive PCa from patients with indolent PCa and/or patients with clinically localized and/or organ confined PCa from patients with extraprostatic extension of PCa and/or PCa with metastatic spread to lymph nodes or bone marrow using said antibody. Excerpt(s): This invention relates to high affinity immunoreagents which are specific for the single-chain, intact (i.e. not internally-cleaved) form(s) of prostate specific antigen (PSA or hK3). It also relates to the discrimination of prostate cancer from healthy asymptomatic men or benign prostatic conditions by an analytically sensitive immunoassay, employing the aforementioned immunoreagents, for the specific determination of the single-chain, intact (not internally cleaved) form(s) of free, noncomplexed PSA (free SCINT PSA), or by combining the result from this immunoassay with immunoassays measuring any other forms of the prostatic kallikreins, PSA or hK2, either by forming various ratios of these or by combining them with other means, e.g. using logistic regression and/or artificial neural networks. The invention may be used for detection of prostate cancer both in screening of asymptomatic individuals as well as in distinguishing cancer from benign conditions in men presenting with clinical symptoms (e.g. lower urinary tract symptoms, LUTS). Further, the invention may be used to improve the staging and grading of prostate cancer as well as to provide improved means to detect recurrency of cancer at early stage and provide improved means to monitor therapeutic response at various stages of disease. Suitable biological specimens for the immunoassay determinations are mainly serum, plasma or whole blood samples, but the invention may also be applied to other

Benign Prostatic Hyperplasia

biological fluids such as urine and seminal fluid samples. The publications and other materials used herein to illuminate the background of the invention, and in particular, cases to provide additional details respecting the practice, are incorporated by reference. Prostate-specific antigen (PSA; also designated hK3) and human glandular kallikrein 2 (hK2) are two closely related serine proteases highly expressed, predominantly in prostatic tissue. [Wang et al. Invest Urol 1979; 17:159-163, Lilja J Clin Invest 1985; 76:1899-1903, Chapdelaine et al. FEBS Lett 1988; 236:205-208]. The PSA gene is located on the long arm of chromosome 19 and has >84% nucleotide sequence identity with hK2. The two proteins also show extensive similarity in amino-acid sequence (79%) but the expression rates are quite different (hK2 mRNA levels amount to.about.10-20% of PSA mRNA levels) [Schedlich et al. DNA 1987; 6:429-437]. PSA is synthesized as a 261 amino acid preproform from which the 17-21 amino acid signal peptide is cleaved and released in the secretion process. The remaining zymogen form of PSA is activated to an active serine protease by cleavage of 3-7 amino acid propeptide [Lovgren et al Biochem. Biophys. Res. Comm. 1997; 238; 549-555]. Recently, recombinant hK2 was shown to convert in vitro inactive recombinant proPSA into active mature PSA [Lovgren et al. Biochem Biophys Res Commun 1997; 238:549-555, Takayama et al. J Biol Chem 1997; 272:21582-21588, Kumar et al. Cancer Res 1997; 57:3111-3114]. Therefore, hK2 is likely a physiological activator of proPSA. Enzymatically active PSA is secreted into seminal fluid at high concentrations (0.2-5 mg/mL) [Christensson et al. Eur J Biochem 1990; 194:755-763, Ahlgren et al. 1995 J Androl 16:491-498]. In semen, PSA degrades the seminal vesicle derived gel-forming proteins semenogelin I and II, causing liquefaction of semen and release of progressively motile spermatozoa [Lilja J Clin Invest 1985; 76:1899-1903]. The action of PSA generates hydrolysis of peptide bonds, mainly Cterminal, of certain tyrosine- and glutamine residues in semenogelin I and II [Malm et al. The Prostate 2000; In press]. By contrast, hK2 generates distinctly different cleavage patterns in semenogelin I and II compared to those generated by the action of PSA, though it is presently unclear whether the hK2 action on the gel proteins has physiological significance [Lovgren et al. Eur. J. Biochem. 1999; 262; 781-789]. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Pharmaceutical combination for the treatment of benign prostatic hyperplasia or for the long-term prevention of acute urinary retention Inventor(s): Baiker, Wolfgang; (Volxheim, DE), Mehlburger, Ludwig; (Bingen/Rhein, DE) Correspondence: Boehringer Ingelheim Corporation; 900 Ridgebury Road; P. O. Box 368; Ridgefield; CT; 06877; US Patent Application Number: 20030225118 Date filed: April 24, 2003 Abstract: The present invention relates to a new pharmaceutical combination for treating benign prostatic hyperplasia (BPH) or for the long-term prevention of acute urinary retention (AUR). Excerpt(s): The present invention relates to a pharmaceutical combination suitable for the treatment of benign prostatic hyperplasia or for the long-term prevention of acute urinary retention. BPH, a benign, non-cancerous enlargement of the prostate, is a wellknown complaint in men, which generally comes to medical attention from the age of 50 onwards. About 50% of all men aged over 50 and 95% of all men aged over 70 are affected by it. BPH is a generally progressive condition which in serious cases may endanger kidney function and require surgical intervention. The number of untreated patients runs at over 37 million worldwide. The reduced flow rate and voiding (obstructive) symptoms of BPH are generally considered to be caused by two main factors, the enlarged prostatic gland (the static component), and the tone of the smooth muscle of the stroma and urethra (the dynamic component). Storage (irritative) symptoms have been associated with bladder dysfunction secondary to outflow obstruction. The growth and tone of the prostate compresses or lengthens the urethra, causing the symptoms of urethral blockage and possibly leading to urinary retention.

Excerpt(s): This invention relates to new polypeptides able to bind PSP94 (PSP94binding protein), as well as nucleic acid and amino acid sequences, and the use of these sequences in the diagnosis and prognosis of diseases. This invention also relates to improved diagnostic assays, kit and reagents such as antibodies able to recognize PSP94 or a PSP94-binding protein. The prostate gland, which is found exclusively in male mammals, produces several components of semen and blood and several regulatory peptides. The prostate gland comprises stromal and epithelial cells, the latter group consisting of columnar secretory cells and basal nonsecretory cells. A proliferation of these basal cells as well as stromal cells gives rise to benign prostatic hyperplasia (BPH), which is one common prostate disease. Another common prostate disease is prostatic adenocarcinoma (CaP), which is the most common of the fatal pathophysiological prostate cancers, and involves a malignant transformation of epithelial cells in the peripheral region of the prostate gland. Prostatic adenocarcinoma and benign prostatic hyperplasia are two common prostate diseases, which have a high rate of incidence in the aging human male population.

Regulation of human adenylate cyclase Inventor(s): Zhu, Zhimin; (Waban, MA) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20040063174 Date filed: October 14, 2003 Abstract: Reagents which regulate human adenylate cyclase and reagents which bind to human adenylate cyclase gene products can play a role in preventing, ameliorating, or correcting dysfunctions or diseases including, but not limited to, peripheral and central nervous system disorders, disorders of the genito-urinary system including but not limited to benign prostatic hyperplasia and urinary incontinence, obesity, COPD and diabetes. Excerpt(s): This application incorporates by reference U.S. provisional applications Serial No. 60/247,005 filed Nov. 13, 2000 and U.S. 60/267,181 filed Feb. 8, 2001. The invention relates to a novel human adenylate cyclase and its regulation for therapeutic uses. Cyclases play important roles in the transduction of extracellular signals via their synthesis of "secondary messengers" such as adenosine 3',5'-cyclic phosphate (cyclic adenosine monophosphate, cAMP) and guanosine 3',5'-cyclic phosphate (cyclic guanosine monophosphate, cGMP). Cell surface receptors mediate the transduction of an extracellular signal, such as the binding of a ligand to a receptor, into a signal that is transmitted internally within the cell. The internal signal is carried by secondary messengers, which typically are produced in response to the binding of an external signal. The secondary messengers in turn activate particular proteins and other regulators within the cell which have the potential to regulate expression of specific genes or to alter a metabolic process.

Excerpt(s): The present invention relates to a therapeutic agent for bladder irritative symptoms associated with benign prostatic hyperplasia. Benign prostatic hyperplasia is benign adenoma generated in a transitional zone of the prostate that wraps the urethra. Patients with benign prostatic hyperplasia complain of bladder outlet obstructive symptoms or bladder irritative symptoms. Examples of bladder outlet obstructive symptoms include a hesitation before urine flow starts, straining, a weak urinary stream, an intermittent urinary stream, dribbling at the end of urination, prolongation of urination and overflow incontinence. Examples of bladder irritative symptoms include urinary frequency at daytime, urinary frequency at night, urinary urgency, a feeling of incomplete emptying and a reduced voided volume per micturition. Functional obstruction and mechanical obstruction are involved in the development of these urinary disturbances due to benign prostatic hyperplasia. Further, these functional and mechanical obstructions cause secondary changes in detrusor muscle or nerves, which induce the complicated pathological phenomena such as bladder irritative symptoms and bladder outlet obstructive symptoms. At present, for examples,.alpha.sub.1-receptor blockers, anti-androgen agents, plant preparations, amino acid preparations, or the like are used as a therapeutic agent for benign prostatic hyperplasia. Among these, examples of the.alpha.sub.1-receptor blockers include tamsulosin hydrochloride, prazosin hydrochloride, terazosin hydrochloride and urapidil. Examples of the antiandrogen agents include chlormadinone acetate, allylestrenol, gestonorone caproate, oxendolone and finasteride. The.alpha.sub.1-receptor blockers inhibit the functional urethral obstruction, that is, contractions of prostatic smooth muscle induced by noradrenaline, secreted by stimulation of the sympathetic nerve, via the.alpha.sub.1receptor. The anti-androgen agents inhibit the mechanical obstruction, that is, a rise in urethral resistance resulting from the pressure caused by the enlarged prostate itself. However, although the.alpha.sub.1-receptor blockers and anti-androgen agents are recognized to be effective for bladder outlet obstructive symptoms of benign prostatic hyperplasia, their effects on improvement of bladder irritative symptoms are insufficient. The plant preparations and amino acid preparations, which have antiinflammatory activity, anti-edema activity, or the like, improve the bladder irritative symptoms by alleviating the outflow obstruction at the bladder neck; but their effects are weak and the dose required is large so that they are a burden to aged people. Under these circumstances, there exists a need for a therapeutic agent to alleviate bladder irritative symptoms.

Use of alpha1-adrenoreceptor antagonists in the prevention and treatment of benign prostatic hyperplasia Inventor(s): Thompson, Timothy C.; (Houston, TX), Wyllie, Michael G.; (New York, NY), Yang, Guang; (Houston, TX) Correspondence: Pfizer Inc; 150 East 42nd Street; 5th Floor - Stop 49; New York; NY; 10017-5612; US Patent Application Number: 20030125335 Date filed: February 18, 2003 Abstract: A method for treating or preventing a BPH in a mammal which comprises administering to said mammal an amount of a drug, comprising an.alpha.sub.1adrenoreceptor antagonist or pharmaceutically acceptable acid addition salt thereof, effective for treating or preventing the BPH. Excerpt(s): This invention relates to the use of.alpha.sub.1-adrenoreceptor antagonists, or pharmaceutically acceptable acid addition salts, thereof for treating or preventing the formation of benign prostatic hyperplasia (BPH) in mammals. More particularly, it relates to a method for preventing the formation of, or reducing, BPH in mammals by administering to said mammals an.alpha.sub.1-adrenoreceptor antagonist or pharmaceutically acceptable acid addition salt thereof. Benign prostatic hyperplasia (BPH) is one of the most common, nonmalignant neoplastic processes to affect the aging man. Symptoms occur in about 50 and up to 80% of men 60 years old and older than 80 years, respectively. In the United States BPH is an important health problem resulting in an estimated 1.7 million visits to physicians offices each year. BPH results from a progressive enlargement of the prostate, leading to urethral constriction, a disturbance in normal urinary outfow, urinary retention and associated irritative symptoms. In symptomatic BPH there appear to be two components of the urethral obstruction: a static component related to prostatic mass and a dynamic component related to the noradrenergic tone in the prostatic and urethral smooth muscle. A number of functional studies have shown that the contractile response is primarily mediated by.alpha.sub.1adrenoreceptors. Autoradiographical data suggest that these are primarily located on stromal smooth muscle. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

ISBN: 0070634130. Summary: Benign prostatic hyperplasia (BPH) is a condition encountered in most aging men. This benign (non-cancerous) overgrowth of the prostate can result in a multitude of lower urinary tract symptoms including dysuria (painful urination), frequency, urgency, and nocturia (getting up to urinate at night), as well as obstructive symptoms such as slow stream, hesitancy, intermittency, straining to void, sense of incomplete emptying, and terminal and postvoid dribbling. This chapter on BPH is from a text on common problems in urology (written for the primary care provider). The authors caution that these symptoms may occur from a multitude of lower urinary tract disorders in both men and women; not all are specific to BPH alone. The authors cover definitions of the condition, epidemiology (incidence and prevalence), etiology (causes), pathophysiology (what goes wrong), diagnosis and diagnostic tests, the differential diagnosis, and treatment options, including watchful waiting, medical management (drug therapy), and surgical treatment. A patient evaluation and care algorithm is provided. Current selection of treatment for a given individual depends on the severity of symptoms, presence or absence of complications, comorbidity, sexual function, physician experience and preferences, patient biases, and the availability and cost of less invasive devices. 3 figures. 6 tables. 3 references.

E-mail: [email protected] PRICE: $125.00, plus shipping and handling. ISBN: 0896038947. Summary: Benign prostatic hyperplasia is enlargement of the prostate gland which results in symptoms affecting urination, in the absence of malignancy (cancer). This chapter on the use of Urolume stents in the management of benign prostatic hyperplasia (BPH) is from a text that was compiled to provide a broad view of prosthetic devices used in urologic surgery. Transurethral resection of the prostate (TURP) is still the traditional therapy of choice for symptomatic BPH. However, there are some alternative surgical options available for BPH, including the minimally invasive approach using a permanent endoprosthetic stent to tackle the problem of bladder outlet obstruction (secondary to BPH). An example of such a stent is the Urolume stent, which is a mesh of corrosion-resistant nickel superalloy wire woven into a flexible, expandable tube. The authors discuss the history of the Urolume stent, stent insertion, and results from a randomized, controlled trial using this stent. The authors conclude that a permanently implanted Urolume prostatic urethral stent, with its low morbidity (complications) via a reduced operating time and hospital stay, is a safe alternative to TURP. It appears to produce only slightly more postoperative discomfort and pain during intercourse than a TURP, and the majority of such symptoms resolve eventually. The authors note that TURP should still remain as the standard treatment for BPH in the fit, nongeriatric patient until such time when the problems of intrastent hyperplasia and epithelialization failure are resolved and probably when longer term results, with up to 5 years of followup, of the Urolume stents are available. 12 figures. 2 tables. 25 references.

Fax (301) 824-7390. Website: lww.com. PRICE: $199.00 plus shipping and handling. ISBN: 0397587376. Summary: Interstitial laser coagulation (ILC) of benign prostatic hyperplasia (BPH) is used to decrease urethral obstruction and both obstructive and irritative symptoms. In this technique, coagulation necrosis (tissue death) is generated well inside the adenoma, rather than at its urethral surface. This chapter on ILC is from an exhaustive textbook on urologic surgery. Candidates for ILC are all patients with moderate and severe voiding symptoms due to mechanical obstruction of the bladder outlet due to BPH who are otherwise candidates for surgical intervention, either transurethral or open. Because ILC has essentially no major morbidity and can be performed with local anesthesia, even high risk patients who are not candidates for transurethral resection of the prostate (TURP) can be considered for ILC treatment. Recurrent or residual BPH after previous prostate surgery, laser treatment, or microwave treatment can also be treated by ILC. The author details the surgical techniques used and the anticipated outcomes. ILC uses Nd:YAG or diode lasers, as they offer relatively deep penetration in water, efficient volumetric heating (permitting necrotic temperatures deep into tissues) and the ability

to be delivered with flexible optical fibers. ILC can be performed using the transurethral approach or the percutaneous (perineal) approach. Complications include retrograde ejaculation (0 to 12 percent incidence), the need for repeat BPH treatment, transient irritative symptoms, urethral strictures, and uncomplicated urinary tract infections; no study reported any occurrence of impotence (erectile dysfunction) or sustained urinary incontinence. 8 figures. 5 tables. 15 references. •

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: Symptomatic benign prostatic hyperplasia (BPH) is a common disease that affects all men with aging. BPH is currently considered a disease that affects the quality of life; therefore, treatments are currently designed to relieve symptoms and reduce side effects. This chapter on the use of the alpha blocker, tamsulosin, in the clinical management of BPH is from a textbook that compiles data and commentary from the world's leading experts in this field. Approximately 80 percent of the patients receiving drug therapy for BPH are prescribed alpha blockers by their primary care physician. The first two selective, long acting alpha 1 receptor antagonists to be approved for treatment of BPH in the United States were terazosin and doxazosin. Tamsulosin hydrochloride (brand name Flomax), a new class of sulfonyl derivative, a uroselective alpha adrenergic blocker, was FDA-approved in 1997. The authors cover the scientific rationale for this drug use, the structure and classification of alpha adrenergic receptors, the clinical pharmacology and pharmacokinetics of tamsulosin, drug interactions, carcinogenesis (development of cancer), adverse reactions to the drug, and clinical studies investigating its use and efficacy. The authors conclude that tamsulosin overall has several advantages over the alpha blockers currently in use. The long action of tamsulosin allows for once a day dosing. Its therapeutic effect, as indicated by improvements in symptoms score, is realized as early as one week after treatment. Additional advantages include the lack of side effects, even in patients at risk of postural hypotension (low blood pressure) such as the elderly and those on multiple cardiac medications, and patients who have comorbid conditions such as diabetes and cardiac disease. Finally, the lower side effect profile of tamsulosin may also allow its use in combination with other relaxants and newer agents in the treatment of lower urinary tract symptoms. 2 tables. 99 references.

Summary: The increasing demand for less invasive and more economical surgical therapies to treat benign prostatic hyperplasia (BPH) has led to the technique of

transurethral needle ablation (TUNA), which uses radio frequency energy to perform thermotherapy of the prostate. The TUNA system consists of an energy generator, and an endoscopic instrument for delivering energy into the prostate. The machine also has a urethral cooling system to prevent urethral heat injury. The mechanism of TUNA efficacy is believed to be tissue coagulative necrosis (death), which results in scarring, softening, and a decrease in volume of the prostate. This chapter on the use of TUNA in the clinical management of BPH is from a textbook that compiles data and commentary from the world's leading experts in this field. In this chapter, the authors discuss the physical properties and medical and surgical applications of radiofrequency, the use of radiofrequency in BPH, dosimetry research on this technique, the TUNA procedure itself (including anesthesia requirement during TUNA, clinical results, potential variability of results, and possible adverse events), the mechanism of action of TUNA, and cost considerations. The authors conclude that TUNA is an exciting new minimally invasive treatment for symptomatic BPH. The procedure is tolerated well by patients under regional prostatic block in a clinic setting without the need for hospitalization. The treatment has a particular role in elderly patients with high surgical risk. Furthermore, the lack of significant risks, specifically those of urinary incontinence and sexual dysfunction, makes this treatment more attractive than TURP for many patients. 9 figures. 2 tables. 31 references. •

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: The prostate gland is dependent on androgenic (male hormones) stimulation. Depriving the prostate of its testosterone support is an established treatment for benign prostatic hyperplasia (BPH). This chapter on the hormonal therapy in the clinical management of BPH is from a textbook that compiles data and commentary from the world's leading experts in this field. The author describes the development of finasteride, a 5 alpha reductase inhibitor, the studies that investigated the safety and efficacy of finasteride, the use of finasteride to reduce acute urinary retention and the need for surgery, combination therapy, the composition of the prostate response to finasteride, the biological variability of serum prostate specific antigen (PSA) and finasteride, and other types of hormonal therapy used in men with BPH. Approximately one third to one half of patients with BPH who are treated with finasteride in clinical studies have clinically significant improvements, while modest benefits overall were seen in the study population. Uncontrolled studies suggest that the response to therapy may be sustained for up to 6 years, although it is yet to be determined whether the progression of BPH with time can be prevented. Given its minimal side effects, finasteride should be considered an acceptable treatment option for a select group of patients with BPH. There also appears to be a benefit to finasteride in reducing the incidence of acute urinary retention and BPH related surgical interventions by up to nearly 50 percent when used chronically for over 2 years. With regard to prostate cancer, patients should be informed of the effect that finasteride has in lowering serum PSA levels and the potential impact this may have on the detection of prostate cancer. 6 figures. 53 references.

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: This chapter on health related quality of life in men with benign prostatic hyperplasia (BPH) is from a textbook that compiles data and commentary from the world's leading experts in this field. The authors note that, in some men, BPH can lead to lower urinary tract symptoms (LUTS) and other BPH complications (such as acute urinary retention or obstructive uropathy) that can affect the health of the men who have it, giving this condition its morbidity. Without these manifestations, BPH would be more of a histologic curiosity than a disease. The authors discuss the goals of treatment for BPH, how health related quality of life (HRQoL) is defined and measured, disease specific and generic measures of health status, specific measures of health status for BPH, the relationship between anatomic and physiologic measures of BPH severity with LUTS, and changes in LUTS and health status with treatment for BPH. The authors conclude that men with LUTS have decrements in both disease specific and generic measures of HRQoL. LUTS levels correlated better with these higher order health status measures than measures of the anatomic or physiologic severity of BPH. The findings document the morbidity (illness) of this common condition. Treatment can result in improvement in disease specific measures of health status, and treatment with prostatectomy results in improvements in generic measures of health status as well. 5 figures. 2 tables. 75 references.

E-mail: [email protected]. Website: www.harcourt-international.com. PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: This chapter on socioeconomics and trends in the management of benign prostatic hyperplasia (BPH) is from a textbook that compiles data and commentary from the world's leading experts in this field. In addition to the patient and his physician, a third interested party is increasingly becoming a part of decision making in the management of BPH: the payer of the costs of health care. Economic issues surrounding the diagnosis and treatment of BPH are becoming a major area of concern for payers, in view of the prevalence of the disease, an aging population, and the attendant increasing numbers of men in the BPH age range. The issue is further complicated by the recent explosion in the numbers of new emerging strategies of BPH management. The author reviews the current costs of BPH management, changing treatment patterns and their impact on urologists, future costs of BPH, and means of cost containment. The author concludes that the most costly aspect of any strategy of BPH management is its failure rate and lack of durability. Ineffective treatments, even marginally effective treatments, although initially less costly than prostatectomy, become very expensive when the costs of definitive therapies such as surgery must be

inevitably added to costs incurred during the course of the ineffective or unsuccessful treatment. Proven clinical effectiveness and cost effectiveness, documented in properly performed prospective randomized clinical trials, are essential. 2 figures. 12 tables. 28 references. •

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: This chapter on the epidemiology, natural history, and pathogenesis of benign prostatic hyperplasia (BPH) is from a textbook that compiles data and commentary from the world's leading experts in this field. BPH is one of the most common neoplasms affecting men over 50 years of age. If untreated, it can result in acute urinary retention, infection, stones, and upper urinary tract deterioration. Even though several associations and trends have been observed, the etiology, natural history, and pathophysiology of this disease are far from clear. The lack of correlation between histologic BPH, clinical symptoms, and physical obstruction has been a major cause of ambiguity in the understanding of this disease. The authors discuss factors affecting the incidence of BPH, including age, family history, geographic factors, income, testicular function, obesity, hypertension, diabetes mellitus, liver cirrhosis, vasectomy, sexual activity, smoking, alcohol, and diet. A final section of the chapter considers the risk for prostatectomy in men with BPH; an increasing burden of urinary symptoms as men age is an important source of morbidity in BPH as well as an important determinant of risk of prostatectomy. 68 references.

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: This chapter on the use of open prostatectomy (removal of the prostate) in the clinical management of benign prostatic hyperplasia (BPH) is from a textbook that compiles data and commentary from the world's leading experts in this field. Simple prostatectomy is an efficient, highly effective, and safe surgical treatment for benign obstructive prostatic disease. Successful surgical outcomes remain reliant on proper patient selection and adherence to proven surgical principles. The frequency of this procedure has decreased with the advent of improved endoscopic instruments, drug therapy, and minimally invasive procedures, together with early detection and treatment of incipient BPH. The authors discuss patient assessment and indications, the preoperative management of the patient, selection of open prostatectomy procedure, the transvesical (suprapubic) prostatectomy, transcapsular (retropubic) prostatectomy, and the complications of open prostatectomy. The authors estimate that open prostatectomy is a procedure which is required in approximately 3 to 5 percent of patients with obstructive BPH. The open prostatectomy techniques have surgical morbidity

PRICE: $149.00 plus shipping and handling. ISBN: 0443056374. Summary: While transurethral resection of the prostate (TURP) is the gold standard for the treatment of bladder outlet obstruction (BOO), it is associated with certain complications. Urinary stents, however, offer safe and effective alternatives in the poor surgical risk patient with BOO or in those patients with obstructive prostatic carcinoma (prostate cancer). This chapter on the use of stents for the clinical management of benign prostatic hyperplasia (BPH) is from a textbook that compiles data and commentary from the world's leading experts in this field. The authors discuss both temporary and permanent prostatic urethral stents, and the 5 year results of the North American Multicenter clinical trial using the UroLume permanent stent for patients with BOO. The ideal stent is easy to insert and remove, self-expanding, has a large internal diameter (large enough to be able to pass a cystoscope through it), and is constructed of

Books

199

material that is biocompatible and the least subject to corrosion. A major side effect of the original metallic stents was encrustation and obstruction. In subsequent models, this has been resolved by having the stent woven in mesh form, which allows tissue to grow through and epithelialize the internal surface. In the US, the only stent that has FDA approval is the UroLume wallstent, a stent made of a superalloy of steel in mesh form, which is inserted using a special cystoscopically guided device. The stent is available in three different lengths (2, 3, 4 cm) to accommodate varying lengths of urethral strictures. The downside appears to be the irritative symptoms that up to 30 percent of patients experience, and the operative procedure required to remove it when necessary. However, stents appear to be effective treatment in patients who are poor candidates for surgery. 5 figures. 1 table. 26 references.

Box 53889, Boulder, CO 80322-3889. (800) 333-9037 or (303) 604-1465. Summary: This health newsletter article discusses enlarged prostate gland (benign prostatic hyperplasia), a common problem that affects half of men in their 60s and close to 80 percent of men in their 80s. The prostate gland is located just below the bladder and surrounds the urethra, the tube that drains the bladder. This gland often enlarges with age and constricts the urethra, making it more difficult for urine to pass through. Signs and symptoms of benign prostatic hyperplasia (BPH) may include excessive urination at night, a weak urine stream, stopping and starting while urinating, a frequent urge to urinate, and a feeling that the bladder has not been emptied completely. Diagnosis includes a symptom questionnaire, a urine test to rule out infection, a prostate specific antigen (PSA) test, and a digital rectal exam (DRE) to rule out prostate cancer, and sometimes more tests including cystoscopy and urine flow tests. Generally, no treatment is required for mild BPH symptoms. Monitoring the situation and simple lifestyle changes may be all that is necessary. For men with moderate to severe symptoms, treatment options include oral medications, surgery, and minimally invasive techniques. Drug options include alpha blockers, finasteride, and plant extracts (including saw palmetto). Surgical treatments include transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), open prostatectomy (removal of the prostate), microwave and radiofrequency, laser therapy, and stents. One sidebar summarizes lifestyle changes that may be recommended to help men deal with symptoms of BPH. 1 figure. 1 table.

Academic Periodicals covering Benign Prostatic Hyperplasia Numerous periodicals are currently indexed within the National Library of Medicine’s PubMed database that are known to publish articles relating to benign prostatic hyperplasia.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.

U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for benign prostatic hyperplasia. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with benign prostatic hyperplasia. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks,

208

Terazosin •

Systemic - U.S. Brands: Hytrin http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202546.html

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.

Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.

209

PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

217

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.

Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •

CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.

•

Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.

18 Adapted 19

from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.

The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

219

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on benign prostatic hyperplasia can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.

Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to benign prostatic hyperplasia. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to benign prostatic hyperplasia. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas.

Contact: Available from American Foundation for Urologic Disease. 1126 North Charles Street, Baltimore, MD 21201. (800) 242-2383 or (410) 468-1800. Fax (410) 468-1808. Website: www.afud.org. PRICE: Single copy free. Summary: This booklet was written to help patients make informed choices about treatment options for their benign prostatic hyperplasia (BPH). The brochure begins with a description of the prostate and its role. More than half of men over age 60 have BPH, an enlarged prostate that is not cancerous. BPH affects the inner part of the prostate first. As a result, the prostate may begin to squeeze the urethra. This sometimes causes problems in urinating. BPH generally does not interfere with sexual functioning. BPH should be treated only if the symptoms are severe enough to affect lifestyle or if the urinary tract is seriously affected. Currently, the main ways of dealing with BPH are watchful waiting, alpha-blocker drug treatment, finasteride drug treatment, and surgery. Surgery often does the best job of relieving symptoms, but it also has more risk than the other treatments. The brochure also describes laser surgery and other new treatments, including electrovaporization and thermal therapy. The brochure outlines the benefits and risks of each type of traditional therapy. The booklet concludes with a glossary of related terms; a pretest and answers are also included.

(800) 457-2752. Fax (510) 601-1008. E-mail: [email protected]. Website: www.parlay.com. PRICE: Single copy free. Summary: This brief fact sheet offers basic information about enlarged prostate glands (benign prostatic hyperplasia, or BPH). When the prostate gland becomes enlarged, it can partially or entirely block the urethra, making urination difficult or impossible. The prostate enlarges normally as part of the aging process, starting in a man's late 40s. The fact sheet reviews the symptoms of BPH, tests that will be performed to confirm a diagnosis of BPH, and treatment options. The most common form of treatment for an enlarged prostate is oral medication. Surgery is also a successful method of treatment (usually transurethral prostate resection), but can adversely affect sexual potency and control of urination. Readers are encouraged to have a yearly digital rectal examination to detect and monitor an enlarged prostate. 1 figure.

Summary: This brochure describes a particular prostate disease: noncancerous enlargement of the prostate or benign prostatic hyperplasia (BPH). Topics include the anatomy and physiology of the prostate, a definition of BPH, the symptoms of BPH, how it is diagnosed, how it differs from prostate cancer, when to see a specialist, when BPH requires treatment, surgical treatment, nonsurgical treatments, and lifestyle issues. A brief quiz at the beginning of the brochure emphasizes the information that all men should know. The prostate is a gland of the male reproductive system; the gland is made up largely of muscular and glandular tissues and its main function is to produce fluid for semen, which transports sperm. The symptoms of BPH can include a weak urinary stream, difficulty starting urination, interruption of the stream (stopping and starting), pain or burning on urination, urgency (difficulty postponing urination), frequent urination, and awakening frequently at night to urinate. Diagnostic methods include a thorough medical history and the physical examination, including the digital rectal examination. For BPH, if men are not bothered by their symptoms, they may just be put on a program of watchful waiting, which entails regular followup but no actual treatment. Other treatments are drug therapy, thermal (heat based) therapy, surgery, and alternative treatments (such as herbal remedies). The brochure describes the four types of surgery that may be used for BPH: transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), open prostatectomy (removal of the prostate), and laser surgery. The brochure reiterates the differences between BPH and prostate cancer and cautions readers that they must stay vigilant for the signs of prostate cancer, which is best treated when detected early. The brochure concludes with a glossary of terms used in the text and the answers to the pretest. 5 figures. •

Enlarged Prostate: Medication or Surgery Source: Hanover, MD: American Prostate Society. 1994. 4 p. Contact: Available from American Prostate Society. 1340-F Charwood Road, Hanover, MD 21076-3169. (410) 859-3735. E-mail: [email protected]. Web site: http://www.ameripros.org. PRICE: Single copy free; bulk copies available. Summary: This brochure helps men with prostatic enlargement make the decision between medications or surgery for treatment. The brochure first describes the use of flutamide, finasteride (Proscar), and terazosin (Hytrin) and the drawbacks to each. The authors discuss two main objections to medication: cost factors and the lack of opportunity to detect prostatic cancer. The man's health, age, and degree of prostatic enlargement will affect the decision regarding treatment modality. Up to half of all men, properly evaluated for medication, could avoid surgery using Proscar or Hytrin under a physician's care. The remainder of the brochure outlines the steps taken prior to, during, and after surgery for prostatic enlargement. More than 400,000 men each year undergo surgery to correct prostate enlargement, at a cost of more than three billion dollars per year. The brochure lists the conditions that might require surgery (as opposed to watchful waiting): hesitating or difficult urination; incomplete voiding; recurring bladder infections; inability to control urination; and reduced kidney function. The brochure focuses on the transurethral resection of the prostate, or TURP, procedure. One series of diagrams illustrates how the enlarging prostate affects urination at different points in its enlargement. 5 references. (AA-M).

Summary: This chapter, from a handbook of instructions for older people and their caregivers, provides an overview of benign prostatic hypertrophy. As men get older, the prostate gland gets larger, a condition known as benign prostatic hyperplasia (BPH). In some men, an enlarged prostate may cause problems because it can put pressure on the bladder, resulting in the frequent release of small quantities of urine. Sometimes the interference of the enlarged prostate with the bladder area causes minor incontinence, or dribbling. Other symptoms may be hesitancy, frequency of urination, nocturia (increased urination at night), and urgency. Surgical removal of part of the enlarged prostate is the usual treatment for BPH. An alternative, nonsurgical treatment with drugs alone can be used when surgery poses a risk to the patient. Drugs used include finasteride (Proscar), which acts by decreasing the level of a male hormone in the prostate gland, and terazosin (Hytrin), which relaxes the muscles where the bladder empties, reducing the obstruction caused by prostate gland enlargement. The section concludes with a description of the symptoms which should prompt a call to the health care provider's office. These include a change in the ability to urinate, blood in the urine,

Contact: Available from National Kidney and Urologic Diseases Information Clearinghouse (NKUDIC). 3 Information Way, Bethesda, MD 20892-3580. (800) 891-5390 or (301) 654-4415. Fax (301)634-0716. E-mail: [email protected]. Website: http://www.niddk.nih.gov/health/kidney/nkudic.htm. PRICE: Full-text available online at no charge; single copy free; bulk orders available. Order number: KU-22. Summary: This fact sheet describes benign prostatic hyperplasia (BPH), the enlargement of the prostate gland associated with aging. Though the prostate continues to grow during most of a man's life, the enlargement does not usually cause problems until late in life. As the prostate enlarges, the layer of tissue surrounding it stops it from expanding, causing the gland to press against the urethra, like a clamp on a garden hose. The narrowing of the urethra and partial emptying of the bladder cause many of the problems associated with BPH. The fact sheet describes the theories regarding the cause of BPH, the symptoms, diagnostic tests used to confirm the condition (including the digital rectal exam, the prostate specific antigen, or PSA, blood test, rectal ultrasound, urine flow study, intravenous pyelogram or IVP, and cystoscopy), and treatment options. Treatment options include watchful waiting, which entails monitoring the patient regularly but not undertaking any interventions; drug therapy, including the use of finasteride and the alpha blockers terazosin, doxazosin, and tamsulosin; transurethral microwave procedures (TUMT); transurethral needle ablation (TUNA); and surgical options, including transurethral (TURP), open, or laser surgery. The fact sheet then reviews the postoperative recovery time and what patients can expect during this process. Additional topics covered include postoperative problems with urinating, bleeding, and sexual function after surgery (including erections, ejaculation, and orgasm). The fact sheet encourages men to continue to have a rectal exam once a year, even after surgery. Although some signs of BPH and prostate cancer are the same, having BPH does not seem to increase the chances of getting prostate cancer. Nevertheless, a man who has BPH may have undetected prostate cancer at the same time or may develop prostate cancer in the future. The fact sheet concludes with a brief overview of the current research activities on BPH. Appended to the text are a reading list, a glossary of terms, and a brief description of the National Kidney and Urologic Diseases Information Clearinghouse (NKUDIC). 3 figures. 7 references.

Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “benign prostatic hyperplasia” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.

Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21

Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.

Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

In microbiology, the adjustment of bacterial physiology to a new environment. [EU] Adenine: A purine base and a fundamental unit of adenine nucleotides. [NIH] Adenocarcinoma: A malignant epithelial tumor with a glandular organization. [NIH]

244

Benign Prostatic Hyperplasia

Adenoma: A benign epithelial tumor with a glandular organization. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adenosine Monophosphate: Adenylic acid. Adenine nucleotide containing one phosphate group esterified to the sugar moiety in the 2'-, 3'-, or 5'-position. [NIH] Adenosine Triphosphate: Adenosine 5'-(tetrahydrogen triphosphate). An adenine nucleotide containing three phosphate groups esterified to the sugar moiety. In addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter. [NIH] Adenylate Cyclase: An enzyme of the lyase class that catalyzes the formation of cyclic AMP and pyrophosphate from ATP. EC 4.6.1.1. [NIH] Adipocytes: Fat-storing cells found mostly in the abdominal cavity and subcutaneous tissue. Fat is usually stored in the form of tryglycerides. [NIH] Adjuvant: A substance which aids another, such as an auxiliary remedy; in immunology, nonspecific stimulator (e.g., BCG vaccine) of the immune response. [EU] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH] Adrenal Medulla: The inner part of the adrenal gland; it synthesizes, stores and releases catecholamines. [NIH] Adrenaline: A hormone. Also called epinephrine. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU] Adrenergic Antagonists: Drugs that bind to but do not activate adrenergic receptors. Adrenergic antagonists block the actions of the endogenous adrenergic transmitters epinephrine and norepinephrine. [NIH] Adrenoreceptor: Receptors specifically sensitive to and operated by adrenaline and/or noradrenaline and related sympathomimetic drugs. Adrenoreceptor is an alternative name. [NIH]

Adverse Effect: An unwanted side effect of treatment. [NIH] Afferent: Concerned with the transmission of neural impulse toward the central part of the nervous system. [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Age Groups: Persons classified by age from birth (infant, newborn) to octogenarians and older (aged, 80 and over). [NIH] Aged, 80 and Over: A person 80 years of age and older. [NIH]

C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P.
