Abstract
BACKGROUND Between 1999 and 2009 in the United Kingdom, 82,429 men between 50 and 69 years of age received a prostate-specific antigen (PSA) test. Localized prostate cancer was diagnosed in 2664 men. Of these men, 1643 were enrolled in a trial to evaluate the effectiveness of treatments, with 545 randomly assigned to receive active monitoring, 553 to undergo prostatectomy, and 545 to undergo radiotherapy. METHODS At a median follow-up of 15 years (range, 11 to 21), we compared the results in this population with respect to death from prostate cancer (the primary outcome) and death from any cause, metastases, disease progression, and initiation of long-term androgen-deprivation therapy (secondary outcomes). RESULTS Follow-up was complete for 1610 patients (98%). A risk-stratification analysis showed that more than one third of the men had intermediate or high-risk disease at diagnosis. Death from prostate cancer occurred in 45 men (2.7%): 17 (3.1%) in the active-monitoring group, 12 (2.2%) in the prostatectomy group, and 16 (2.9%) in the radiotherapy group (P = 0.53 for the overall comparison). Death from any cause occurred in 356 men (21.7%), with similar numbers in all three groups. Metastases developed in 51 men (9.4%) in the active-monitoring group, in 26 (4.7%) in the prostatectomy group, and in 27 (5.0%) in the radiotherapy group. Long-term androgen-deprivation therapy was initiated in 69 men (12.7%), 40 (7.2%), and 42 (7.7%), respectively; clinical progression occurred in 141 men (25.9%), 58 (10.5%), and 60 (11.0%), respectively. In the active-monitoring group, 133 men (24.4%) were alive without any prostate cancer treatment at the end of follow-up. No differential effects on cancer-specific mortality were noted in relation to the baseline PSA level, tumor stage or grade, or risk-stratification score. No treatment complications were reported after the 10-year analysis. CONCLUSIONS After 15 years of follow-up, prostate cancer-specific mortality was low regardless of the treatment assigned. Thus, the choice of therapy involves weighing trade-offs between benefits and harms associated with treatments for localized prostate cancer.

Abstract
Outcomes after Localized Prostate Cancer TreatmentDonovan et al. present the long-term patient-reported outcomes of 1643 randomly assigned participants in the ProtecT (Prostate Testing for Cancer and Treatment) trial. Functional and quality-of-life impacts of prostatectomy, radiotherapy with neoadjuvant androgen deprivation, and active monitoring are described. Over the trial period from 7 to 12 years, generic quality-of-life scores were similar among all groups, with varying degrees of impact on urinary leakage, sexual function, and fecal leakage depending on the treatment group.

Abstract
OBJECTIVES Active surveillance (AS) enables men with low risk, localised prostate cancer (PCa) to avoid radical treatment unless progression occurs; lack of reliable AS protocols to determine progression leaves uncertainties for men and clinicians. This study investigated men's strategies for coping with the uncertainties of active monitoring (AM, a surveillance strategy within the Prostate testing for cancer and Treatment, ProtecT trial) over the longer term and implications for optimising supportive care. DESIGN Longitudinal serial in-depth qualitative interviews every 2-3 years for a median 7 (range 6-14) years following diagnosis. SETTING Four centres within the UK Protect trial. PARTICIPANTS Purposive sample of 20 men with localised PCa: median age at diagnosis 64 years (range 52-68); 15 (75%) had low-risk PCa; 12 randomly allocated to, 8 choosing AM. Eleven men continued with AM throughout the study period (median 7 years). Nine received radical treatment after a median 4 years (range 0.8-13.8 years). INTERVENTION AM: 3-monthly serum prostate-specific antigen (PSA)-level assessment (year 1), 6-12 monthly thereafter; increase in PSA ≥50% during previous 12 months or patient/clinician concern triggered review. MAIN OUTCOMES Thematic analysis of 73 interviews identified strategies to accommodate uncertainty and anxiety of living with untreated cancer; implications for patient care. RESULTS Men sought clarity, control or reassurance, with contextual factors mediating individual responses. Trust in the clinical team was critical for men in balancing anxiety and facilitating successful management change/continued monitoring. Only men from ProtecT were included; men outside ProtecT may have different experiences. CONCLUSION Men looked to clinicians for clarity, control and reassurance. Where provided, men felt comfortable continuing AM or having radical treatments when indicated. Clinicians build patient trust by clearly describing uncertainties, allowing patients control wherever possible and being aware of how context influences individual responses. Insights indicate need for supportive services to build trust and patient engagement over the long term. TRIAL REGISTRATION NUMBER ISRCTN20141297; Pre-results.

Abstract
BACKGROUND There is limited evidence relating to the cost-effectiveness of treatments for localised prostate cancer. METHODS The cost-effectiveness of active monitoring, surgery, and radiotherapy was evaluated within the Prostate Testing for Cancer and Treatment (ProtecT) randomised controlled trial from a UK NHS perspective at 10 years' median follow-up. Prostate cancer resource-use collected from hospital records and trial participants was valued using UK reference-costs. QALYs (quality-adjusted-life-years) were calculated from patient-reported EQ-5D-3L measurements. Adjusted mean costs, QALYs, and incremental cost-effectiveness ratios were calculated; cost-effectiveness acceptability curves and sensitivity analyses addressed uncertainty; subgroup analyses considered age and disease-risk. RESULTS Adjusted mean QALYs were similar between groups: 6.89 (active monitoring), 7.09 (radiotherapy), and 6.91 (surgery). Active monitoring had lower adjusted mean costs (£5913) than radiotherapy (£7361) and surgery (£7519). Radiotherapy was the most likely (58% probability) cost-effective option at the UK NICE willingness-to-pay threshold (£20,000 per QALY). Subgroup analyses confirmed radiotherapy was cost-effective for older men and intermediate/high-risk disease groups; active monitoring was more likely to be the cost-effective option for younger men and low-risk groups. CONCLUSIONS Longer follow-up and modelling are required to determine the most cost-effective treatment for localised prostate cancer over a man's lifetime.

Abstract
BACKGROUND Prostate cancer is the most common cancer among men in the UK. Prostate-specific antigen testing followed by biopsy leads to overdetection, overtreatment as well as undertreatment of the disease. Evidence of treatment effectiveness has lacked because of the paucity of randomised controlled trials comparing conventional treatments. OBJECTIVES To evaluate the effectiveness of conventional treatments for localised prostate cancer (active monitoring, radical prostatectomy and radical radiotherapy) in men aged 50-69 years. DESIGN A prospective, multicentre prostate-specific antigen testing programme followed by a randomised trial of treatment, with a comprehensive cohort follow-up. SETTING Prostate-specific antigen testing in primary care and treatment in nine urology departments in the UK. PARTICIPANTS Between 2001 and 2009, 228,966 men aged 50-69 years received an invitation to attend an appointment for information about the Prostate testing for cancer and Treatment (ProtecT) study and a prostate-specific antigen test; 82,429 men were tested, 2664 were diagnosed with localised prostate cancer, 1643 agreed to randomisation to active monitoring (n = 545), radical prostatectomy (n = 553) or radical radiotherapy (n = 545) and 997 chose a treatment. INTERVENTIONS The interventions were active monitoring, radical prostatectomy and radical radiotherapy. TRIAL PRIMARY OUTCOME MEASURE Definite or probable disease-specific mortality at the 10-year median follow-up in randomised participants. SECONDARY OUTCOME MEASURES Overall mortality, metastases, disease progression, treatment complications, resource utilisation and patient-reported outcomes. RESULTS There were no statistically significant differences between the groups for 17 prostate cancer-specific (p = 0.48) and 169 all-cause (p = 0.87) deaths. Eight men died of prostate cancer in the active monitoring group (1.5 per 1000 person-years, 95% confidence interval 0.7 to 3.0); five died of prostate cancer in the radical prostatectomy group (0.9 per 1000 person-years, 95% confidence interval 0.4 to 2.2 per 1000 person years) and four died of prostate cancer in the radical radiotherapy group (0.7 per 1000 person-years, 95% confidence interval 0.3 to 2.0 per 1000 person years). More men developed metastases in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring, n = 33 (6.3 per 1000 person-years, 95% confidence interval 4.5 to 8.8); radical prostatectomy, n = 13 (2.4 per 1000 person-years, 95% confidence interval 1.4 to 4.2 per 1000 person years); and radical radiotherapy, n = 16 (3.0 per 1000 person-years, 95% confidence interval 1.9 to 4.9 per 1000 person-years; p = 0.004). There were higher rates of disease progression in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring (n = 112; 22.9 per 1000 person-years, 95% confidence interval 19.0 to 27.5 per 1000 person years); radical prostatectomy (n = 46; 8.9 per 1000 person-years, 95% confidence interval 6.7 to 11.9 per 1000 person-years); and radical radiotherapy (n = 46; 9.0 per 1000 person-years, 95% confidence interval 6.7 to 12.0 per 1000 person years; p < 0.001). Radical prostatectomy had the greatest impact on sexual function/urinary continence and remained worse than radical radiotherapy and active monitoring. Radical radiotherapy's impact on sexual function was greatest at 6 months, but recovered somewhat in the majority of participants. Sexual and urinary function gradually declined in the active monitoring group. Bowel function was worse with radical radiotherapy at 6 months, but it recovered with the exception of bloody stools. Urinary voiding and nocturia worsened in the radical radiotherapy group at 6 months but recovered. Condition-specific quality-of-life effects mirrored functional changes. No differences in anxiety/depression or generic or cancer-related quality of life were found. At the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year, the probabilities that each arm was the most cost-effective option were 58% (radical radiotherapy), 32% (active monitoring) and 10% (radical prostatectomy). LIMITATIONS A single prostate-specific antigen test and transrectal ultrasound biopsies were used. There were very few non-white men in the trial. The majority of men had low- and intermediate-risk disease. Longer follow-up is needed. CONCLUSIONS At a median follow-up point of 10 years, prostate cancer-specific mortality was low, irrespective of the assigned treatment. Radical prostatectomy and radical radiotherapy reduced disease progression and metastases, but with side effects. Further work is needed to follow up participants at a median of 15 years.

Abstract
BACKGROUND The ProtecT trial reported intention-to-treat analysis of men with localised prostate cancer (PCa) randomly allocated to active monitoring (AM), radical prostatectomy, and external beam radiotherapy. OBJECTIVE To determine report outcomes according to treatment received in men in randomised and treatment choice cohorts. DESIGN, SETTING, AND PARTICIPANTS This study focuses on secondary care. Men with clinically localised prostate cancer at one of nine UK centres were invited to participate in the treatment trial comparing AM, radical prostatectomy, and radiotherapy. INTERVENTION Two cohorts included 1643 men who agreed to be randomised; 997 declined randomisation and chose treatment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Health-related quality of life impacts on urinary, bowel, and sexual function were assessed using patient-reported outcome measures. Analysis was carried out based on treatment received for each cohort and on pooled estimates using meta-analysis. Differences were estimated with adjustment for known prognostic factors using propensity scores. RESULTS AND LIMITATIONS According to treatment received, more men receiving AM died of PCa (AM 1.85%, surgery 0.67%, radiotherapy 0.73%), whilst this difference remained consistent with chance in the randomised cohort (p=0.08); stronger evidence was found in the exploratory analyses (randomised plus choice cohort) when AM was compared with the combined radical treatment group (p=0.003). There was also strong evidence that metastasis (AM 5.6%, surgery 2.4%, radiotherapy 2.7%) and disease progression (AM 20.35%, surgery 5.87%, radiotherapy 6.62%) were more common in the AM group. Compared with AM, there were higher risks of sexual dysfunction (95% at 6mo) and urinary incontinence (55% at 6mo) after surgery, and of sexual dysfunction (88% at 6mo) and bowel dysfunction (5% at 6mo) after radiotherapy. The key limitations are the potential for bias when comparing groups defined by treatment received and outdating of the interventions being evaluated during the lengthy follow-up required in trials of screen-detected PCa. CONCLUSIONS Analyses according to treatment received showed increased rates of disease-related events and lower rates of patient-reported harms in men managed by AM compared with men managed by radical treatment, and stronger evidence of greater PCa mortality in the AM group. PATIENT SUMMARY More than 90 out of every 100 men with localised prostate cancer do not die of prostate cancer within 10yr, irrespective of whether treatment is by means of monitoring, surgery, or radiotherapy. Side effects on sexual and bladder function are much better after active monitoring, but the risks of spreading of prostate cancer are more common.

Abstract
OBJECTIVES To report outcomes from a multiparametric (mp) magnetic resonance imaging (MRI)-based active surveillance programme that did not include performing protocol biopsies after the first confirmatory biopsy. PATIENTS AND METHODS All patients diagnosed with Gleason 3 + 3 prostate cancer because of a raised PSA level who underwent mpMRI after diagnosis were included. Patients were recorded in a prospective clinical database and followed up with PSA monitoring and repeat MRI. In patients who remained on active surveillance after the first MRI (with or without confirmatory biopsy), we investigated PSA dynamics for association with subsequent progression. Comparison between first and second MRI scans was undertaken. Outcomes assessed were: progression to radical therapy at first MRI/confirmatory biopsy and progression to radical therapy in those who remained on active surveillance after first MRI. RESULTS A total of 211 patients were included, with a median of 4.2 years of follow-up. The rate of progression to radical therapy was significantly greater at all stages among patients with visible lesions than in those with initially negative MRI (47/125 (37.6%) vs 11/86 (12.8%); odds ratio 4.1 (95% CI 2.0-8.5), P < 0.001). Only 1/56 patients (1.8%) with negative initial MRI scans who underwent a confirmatory systematic biopsy had upgrading to Gleason 3 + 4 disease. PSA velocity was significantly associated with subsequent progression in patients with negative initial MRI (area under the curve 0.85 [95% CI 0.75-0.94]; P <0.001). Patients with high-risk visible lesions on first MRI who remained on active surveillance had a high risk of subsequent progression 19/76 (25.0%) vs 9/84 (10.7%) for patients with no visible lesions, despite reassuring targeted and systematic confirmatory biopsies and regardless of PSA dynamics. CONCLUSION Men with low-risk Gleason 3 + 3 prostate cancer on active surveillance can forgo protocol biopsies in favour of MRI and PSA monitoring with selective re-biopsy.

Abstract
BACKGROUND Robust data on patient-reported outcome measures comparing treatments for clinically localized prostate cancer are lacking. We investigated the effects of active monitoring, radical prostatectomy, and radical radiotherapy with hormones on patient-reported outcomes. METHODS We compared patient-reported outcomes among 1643 men in the Prostate Testing for Cancer and Treatment (ProtecT) trial who completed questionnaires before diagnosis, at 6 and 12 months after randomization, and annually thereafter. Patients completed validated measures that assessed urinary, bowel, and sexual function and specific effects on quality of life, anxiety and depression, and general health. Cancer-related quality of life was assessed at 5 years. Complete 6-year data were analyzed according to the intention-to-treat principle. RESULTS The rate of questionnaire completion during follow-up was higher than 85% for most measures. Of the three treatments, prostatectomy had the greatest negative effect on sexual function and urinary continence, and although there was some recovery, these outcomes remained worse in the prostatectomy group than in the other groups throughout the trial. The negative effect of radiotherapy on sexual function was greatest at 6 months, but sexual function then recovered somewhat and was stable thereafter; radiotherapy had little effect on urinary continence. Sexual and urinary function declined gradually in the active-monitoring group. Bowel function was worse in the radiotherapy group at 6 months than in the other groups but then recovered somewhat, except for the increasing frequency of bloody stools; bowel function was unchanged in the other groups. Urinary voiding and nocturia were worse in the radiotherapy group at 6 months but then mostly recovered and were similar to the other groups after 12 months. Effects on quality of life mirrored the reported changes in function. No significant differences were observed among the groups in measures of anxiety, depression, or general health-related or cancer-related quality of life. CONCLUSIONS In this analysis of patient-reported outcomes after treatment for localized prostate cancer, patterns of severity, recovery, and decline in urinary, bowel, and sexual function and associated quality of life differed among the three groups.

Abstract
BACKGROUND The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain. METHODS We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545). The primary outcome was prostate-cancer mortality at a median of 10 years of follow-up. Secondary outcomes included the rates of disease progression, metastases, and all-cause deaths. RESULTS There were 17 prostate-cancer-specific deaths overall: 8 in the active-monitoring group (1.5 deaths per 1000 person-years; 95% confidence interval [CI], 0.7 to 3.0), 5 in the surgery group (0.9 per 1000 person-years; 95% CI, 0.4 to 2.2), and 4 in the radiotherapy group (0.7 per 1000 person-years; 95% CI, 0.3 to 2.0); the difference among the groups was not significant (P=0.48 for the overall comparison). In addition, no significant difference was seen among the groups in the number of deaths from any cause (169 deaths overall; P=0.87 for the comparison among the three groups). Metastases developed in more men in the active-monitoring group (33 men; 6.3 events per 1000 person-years; 95% CI, 4.5 to 8.8) than in the surgery group (13 men; 2.4 per 1000 person-years; 95% CI, 1.4 to 4.2) or the radiotherapy group (16 men; 3.0 per 1000 person-years; 95% CI, 1.9 to 4.9) (P=0.004 for the overall comparison). Higher rates of disease progression were seen in the active-monitoring group (112 men; 22.9 events per 1000 person-years; 95% CI, 19.0 to 27.5) than in the surgery group (46 men; 8.9 events per 1000 person-years; 95% CI, 6.7 to 11.9) or the radiotherapy group (46 men; 9.0 events per 1000 person-years; 95% CI, 6.7 to 12.0) (P<0.001 for the overall comparison). CONCLUSIONS At a median of 10 years, prostate-cancer-specific mortality was low irrespective of the treatment assigned, with no significant difference among treatments. Surgery and radiotherapy were associated with lower incidences of disease progression and metastases than was active monitoring.

Abstract
Background Early detection and treatment of asymptomatic men with advanced and high-risk prostate cancer (PCa) may improve survival rates. Objective To determine outcomes for men diagnosed with advanced PCa following prostate-specific antigen (PSA) testing who were excluded from the ProtecT randomised trial. Design, setting, and participants Mortality was compared for 492 men followed up for a median of 7.4 yr to a contemporaneous cohort of men from the UK Anglia Cancer Network (ACN) and with a matched subset from the ACN. Outcome measurements and statistical analysis PCa-specific and all-cause mortality were compared using Kaplan-Meier analysis and Cox's proportional hazards regression. Results and limitations Of the 492 men excluded from the ProtecT cohort, 37 (8%) had metastases (N1, M0 = 5, M1 = 32) and 305 had locally advanced disease (62%). The median PSA was 17 μg/l. Treatments included radical prostatectomy (RP; n = 54; 11%), radiotherapy (RT; n = 245; 50%), androgen deprivation therapy (ADT; n = 122; 25%), other treatments (n = 11; 2%), and unknown (n = 60; 12%). There were 49 PCa-specific deaths (10%), of whom 14 men had received radical treatment (5%); and 129 all-cause deaths (26%). In matched ProtecT and ACN cohorts, 37 (9%) and 64 (16%), respectively, died of PCa, while 89 (22%) and 103 (26%) died of all causes. ProtecT men had a 45% lower risk of death from PCa compared to matched cases (hazard ratio 0.55, 95% confidence interval 0.38–0.83; p = 0.0037), but mortality was similar in those treated radically. The nonrandomised design is a limitation. Conclusions Men with PSA-detected advanced PCa excluded from ProtecT and treated radically had low rates of PCa death at 7.4-yr follow-up. Among men who underwent nonradical treatment, the ProtecT group had a lower rate of PCa death. Early detection through PSA testing, leadtime bias, and group heterogeneity are possible factors in this finding. Patient summary Prostate cancer that has spread outside the prostate gland without causing symptoms can be detected via prostate-specific antigen testing and treated, leading to low rates of death from this disease.

Abstract
Bacillus Calmette Guerin (BCG) intravesical therapy of bladder cancer is arguably the most effective immunotherapy for any human solid tumour. It combines a high incidence of remission induction with a low level of side effects and a low rate of recurrence. Its mechanism, however, remains poorly understood. In this study we have investigated whether gamma delta T lymphocytes, which are known to be activated by mycobacteria, are preferentially induced in patients urine following therapy. This has necessitated the development of a procedure which facilitates the preservation, enrichment and detection of small number of lymphocytes [especially of those bearing gamma delta T cell receptor (TCR)I which appear in patients urine. Here we describe in detail a method for phenotyping of a minor subpopulation of lymphocytes in patients' urine, namely, gamma delta T lymphocytes which comprised less than 0.1% of all urinary sells. Using this technique we have found gamma delta T cells in the urine of all patients. Furthermore, the patients could be separated into 2 distinct groups, with low and high numbers of gamma delta cells (0.5-5% and 5-20% respectively of the CD3 positive cells). The elevation of gamma delta T cells was observed locally but not in peripheral blood and the detected gamma delta T were almost entirely of the V delta 2 gamma 9 subset.

Abstract
PURPOSE New nitric oxide (NO) donating nonsteroidal anti-inflammatory drugs (NSAIDs) have been synthesized to counteract the side effects of conventional NSAIDs. Mounting evidence suggests that NSAIDs may have a possible chemopreventative/therapeutic role in prostate cancer. NO is a powerful biological messenger with multiple cellular effects. We established the effects of 2 of these new drugs in prostate cell systems. MATERIALS AND METHODS We studied the effects of NO-ibuprofen (NCX 2111) and NO-aspirin (NCX 4060) on hormone sensitive (LNCap) and insensitive (PC3) prostate cancer epithelial cell lines as well as primary cultures of prostatic stroma. Proliferation was measured using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazalium bromide) assay to examine proliferation. Subsequently flow cytometry, cell cycle analysis and TUNEL staining were used to look for apoptosis. Caspase-3 expression was also examined in treated cell types. RESULTS NCX 2111 and NCX 4060 were found to be potent inhibitors of proliferation in a dose dependent fashion. The 2 drugs induced apoptosis, as seen by flow cytometry, cell cycle analysis and TUNEL staining, at doses between 10 and 100 microM. These NO-NSAIDs increased caspase-3 expression. NCX 4060 was more effective at lower concentrations (10 microM) but each compound was much more potent than conventional ibuprofen and aspirin at inducing apoptosis and inhibiting proliferation. CONCLUSIONS NO-NSAIDs are potent antiproliferative pro-apoptotic compounds in prostate cell systems. This pro-apoptotic effect is mediated via caspase-3 and it is independent of the type of prostate cell used. These findings have ramifications for the use of these new drugs in prostate cancer chemoprevention or treatment.

Abstract
In human prostate, dehydroepiandrosterone (DHEA) is a substrate for two major metabolic pathways that produce functionally opposing sex steroids. In one pathway, DHEA is converted into potent androgens such as testosterone and 5alpha-dihydrotestosterone. In the other, DHEA is metabolized to 7alpha-hydroxy-DHEA (7HD). Recently, CYP7B, a novel P450 enzyme originally characterized in mouse brain and expressed in rodent prostate, has been found to be responsible for all extrahepatic 7alpha-hydroxylase activity. In this study, we have investigated the expression and function of this novel enzyme in human prostate. We have used reverse transcription combined with PCR and mRNA in situ hybridization to determine and localize the expression of CYP7B mRNA in human benign prostatic hyperplasia. High levels of CYP7B mRNA were localized in the epithelial cells together with estrogen receptor beta (ERbeta). 7alpha-Hydroxylation was the major metabolic fate of DHEA in human prostate. Furthermore, we have shown that human prostate epithelial cells in primary culture maintain a high level of 7alpha-hydroxylase activity, which was enhanced by coculture with stroma cells. To investigate the functional relevance of CYP7B expression to sex-steroid action in prostate, we used transient transfections and ligand binding assay to determine the ability of 7HD to bind and activate the sex-steroid receptors: androgen receptor, ERalpha, and ERbeta. 7HD specifically activates ERbeta-mediated transcription, mimicking the effects of 17beta-estradiol, but has no impact on ERalpha and androgen receptor. Given that DHEA, and its sulfate, circulate at micromolar concentrations, there is a clear possibility that CYP7B generates sufficient 7HD to activate ERbeta over and above that achieved with very low concentrations of intraprostatic 17beta-estradiol. In conclusion, our study suggests that CYP7B catalyzes oxysterol 7alpha-hydroxylation within the human prostate epithelium. By this reaction, an ERbeta-specific agonist, 7HD, is produced. Therefore, CYP7B may be a novel regulator of the androgens/estrogenic balance within the prostate.

Abstract
PURPOSE Considerable evidence has accumulated demonstrating that the 5alpha-reduction of testosterone to dihydrotestosterone occurs more efficiently in the normal and benign hyperplastic prostate than in prostate cancer tissues. Efforts have also been channeled into investigating the distribution of 5alpha-reductase isoenzymes in primary prostate tissues and in "in vitro" cell models of the human prostate. However, no one has, thus far, examined the expression of these isoenzymes in prostate cancer metastasis, although such studies might shed some light on the mechanism(s) responsible for the loss of hormone sensitivity in those tumors. The present report addresses this issue in the hope that this might help to identify the steps leading to the development of prostate cancer metastasis. EXPERIMENTAL DESIGN In the present study we used in situ mRNA hybridization of sections from archival paraffin-embedded material to investigate the expression of 5alpha-reductase type I (5alphaR-I) and type II (5alphaR-II) mRNAs in prostate cancer bony (n = 9) and lymph node (n = 13) metastasis, and compared the mRNA distributions with those observed in sections from primary prostate tumors (n = 12). In parallel, sections were investigated for androgen receptor (AR) mRNA expression, and immunostained for AR and prostate-specific antigen. RESULTS Neither 5alphaR-I nor 5alphaR-II mRNA expression was detected in any of the prostate metastatic lesions, although the same metastatic sites expressed AR mRNA, and stained for cytoplasmic prostate-specific antigen and nuclear AR. In contrast, primary prostate tumors displayed intense staining for 5alphaR-I and 5alphaR-II. CONCLUSION These findings suggest that the loss of 5alpha-reductase mRNA expression in bone and lymph node metastasis may be associated, in part, with the progression of these tumors to androgen insensitivity.

Abstract
The objective of this study was to review the results of our policy of primary radiotherapy (RT) and salvage cystectomy for transitional carcinoma (TCC) of the bladder in the light of changes in our radiotherapy planning procedure, in particular the introduction of CT planning. The case notes of 163 patients treated with radical radiotherapy using a CT planning technique were examined. The main endpoint for assessment was response at the time of the check cystoscopy 6 months after the completion of treatment. In addition survival was estimated by stage of disease and by response at the time of first cystoscopy. Patterns of relapse and time to relapse were analysed. All percentages quoted in the text use the initial 163 patients as the denominator. One hundred patients (61%) achieved a complete response. The complete response rate was significantly related to T stage at presentation being 90% for T1, 75% for T2, and 53% for T3 disease respectively. Of these patients 78 remain disease free in the bladder (47%). Twenty-two have relapsed in the bladder, of whom 5 have also relapsed at metastatic sites. Fifteen patients have relapsed outside the bladder whilst remaining disease free within the bladder. At the time of last follow up or death from other causes 63 of the 100 patients who had a complete response remained disease free with an intact bladder. There were 18 (11%) partial responders. Seven of these patients went on to have a cystectomy. Ten remain alive, 7 disease free, 4 with intact bladders. In 24 patients (15%) there was no response and these patients have all died, the median survival being 10 months. In 21 patients (13%) a postradiotherapy cystoscopy was not performed. In all but one patient, who was lost to follow up, this was because of progressive disease. The median survival of these 20 patients was 6 months. Of the 163 patients 35% are alive and well with an intact bladder. If patients dying from other causes are included then 42% were rendered disease free. Cause specific survival was significantly related to stage of disease at presentation with 5 year actuarial survival being 87%, 48% and 26%, for T1, T2 and T3 disease respectively. Survival was also related to response to treatment at 6 months with 5 year survival being 64%, and 52% for complete and partial responders respectively. Survival was extremely poor for non-responders with only 37.5% surviving 1 year and none 5 years. There was a highly significant relationship between response and the development of, and the time to developing metastatic disease. Of those who exhibited a response 21% developed metastatic disease compared to 78% of non-responders. Salvage cystectomy offers the possibility of cure in those who achieve a complete or partial response with 42% of such patients being rendered disease free. Results however are poor in those who did not respond with all patients dying of their disease. Response rates for all stages, and survival for stages T1 and T2 are much improved from those previously reported from this centre and compare favourably with other published series. These results confirm the place of radiotherapy and salvage cystectomy in the management of TCC of the bladder in selected patients. In about one-third of patients the desired outcome of curing the patient of their cancer with organ preservation is achieved. The prognostic significance of cystoscopic response at 6 months and stage at presentation is confirmed. The outcome for patients with early stage disease is excellent. The relationship between response and the development of metastatic disease would suggest that even if these patients had had a primary cystectomy they may have fared badly, a conclusion supported by the fact that these results are comparable with surgical series. This series supports the role of radiotherapy in the management of this disease and suggests that modern RT techniques including CT planning have had a beneficial effect on the results of radical radiotherapy.

Abstract
Paracrine interactions between primary cultured prostate epithelial cells and stromal fibroblasts were investigated in relation to morphology, growth, androgen sensitivity and secretory activities using co-cultures in which the two populations were separated by a microporous membrane. In this new model system, both cell types maintained several aspects of the differentiated phenotype including the capacity to express 5alpha-reductase iso-enzymes and androgen receptors, to respond to androgens and to secrete prostate-specific antigen by the epithelial cells. Morphological studies demonstrated that the cells grown in co-culture exhibited round nuclei, tonofibrils and microvilli in epithelial cells and elongated nuclei, large amounts of Golgi apparatus and cilia in the fibroblasts, all indicative of the differentiated state. The co-culture system highlights the importance of the metabolic co-operation between prostate fibroblast and epithelial cells for preserving the phenotypic characteristics associated with the human prostate in vivo.

Abstract
The expression and localisation of mRNAs for 5 alpha reductase Type I (5 alpha R-I) and Type II (5 alpha R-II) isoenzymes in human benign prostatic hyperplasia (BPH) were investigated by RT-PCR and by in mini hybridisation (ISH) using digoxigenin labelled riboprobes. In addition, we also examined the isoenzymes mRNA expression in primary BPH cultures of separated stroma/fibroblast and epithelial cells to determine whether primary cultures are appropriate models in which to investigate 5 alpha R activity and regulation. The results demonstrated conclusively the presence of mRNA encoding both isoenzymes in all specimens so far examined. Additionally, the presence of a functional 5 alpha R-I and -II activity in BPH was confirmed by enzyme assays. ISH studies localised the mRNA expression to both the fibroblast/stromal component as well as the epithelial cells of the hyperplastic tissue. In the glandular regions the expression for both isoenzymes was particularly strong in the basal layers of the epithelium whereas mRNA expression in the secretory cells was less pronounced. Expression of 5 alpha R-I and -II mRNAs in fibroblast was on the other hand variable with high expression in some areas and little in others. These findings were supported by our primary culture experiments which demonstrated that both the fibroblast and epithelial cells maintain a capacity to express both isoenzymes in vitro. In the case of the fibroblast, the capacity to express the isoenzymes was maintained following the sequential passaging of the cells up to passage 6, after which the cells no longer expressed either isoenzyme.

Abstract
We have developed a coculture system for primary fibroblast and epithelial cells derived from benign prostatic hyperplasia (BPH) that retained many of the characteristics of the intact human prostate. In contrast to separately cultured prostate fibroblast and epithelial cells, cocultures of fibroblasts and epithelial cells maintained messenger ribonucleic acid expression and functional activity for both isoenzymes of 5 alpha-reductase (type I and type II) as well as maintained expression of androgen receptors and prostate-specific antigen. Furthermore, levels of prostate-specific antigen secreted by cocultured epithelial cells were increased by treatment with androgens, mimicking the situation in the human gland. This contrasted with conventionally cultured fibroblasts or epithelial cells, which failed to express 50 alpha-reductase type II and rapidly lost expression of androgen receptors and androgen sensitivity upon being placed into culture. Electron microscopy demonstrated intracellular structures indicative of the differentiated state of the cocultured cell types, including round nuclei, tonofibrils, and microvilli in epithelial cells and elongated nuclei; large amounts of Golgi and cilia; along with immature collagen fibers in fibroblasts. The present study demonstrates that the coculture model reflects more closely the in vivo system for human BPH and is thus a far more suitable model for investigating the molecular and cellular events that underlie BPH than current in vitro systems.
