Improved Outcomes with Enzalutamide in Biochemically Recurrent Prostate Cancer.

BACKGROUND: Patients with prostate cancer who have high-risk biochemical recurrence have an increased risk of progression. The efficacy and safety of enzalutamide plus androgen-deprivation therapy and enzalutamide monotherapy, as compared with androgen-deprivation therapy alone, are unknown. METHODS: In this phase 3 trial, we enrolled patients with prostate cancer who had high-risk biochemical recurrence with a prostate-specific antigen doubling time of 9 months or less. Patients were randomly assigned, in a 1:1:1 ratio, to receive enzalutamide (160 mg) daily plus leuprolide every 12 weeks (combination group), placebo plus leuprolide (leuprolide-alone group), or enzalutamide monotherapy (monotherapy group). The primary end point was metastasis-free survival, as assessed by blinded independent central review, in the combination group as compared with the leuprolide-alone group. A key secondary end point was metastasis-free survival in the monotherapy group as compared with the leuprolide-alone group. Other secondary end points were patient-reported outcomes and safety. RESULTS: A total of 1068 patients underwent randomization: 355 were assigned to the combination group, 358 to the leuprolide-alone group, and 355 to the monotherapy group. The patients were followed for a median of 60.7 months. At 5 years, metastasis-free survival was 87.3% (95% confidence interval [CI], 83.0 to 90.6) in the combination group, 71.4% (95% CI, 65.7 to 76.3) in the leuprolide-alone group, and 80.0% (95% CI, 75.0 to 84.1) in the monotherapy group. With respect to metastasis-free survival, enzalutamide plus leuprolide was superior to leuprolide alone (hazard ratio for metastasis or death, 0.42; 95% CI, 0.30 to 0.61; P<0.001); enzalutamide monotherapy was also superior to leuprolide alone (hazard ratio for metastasis or death, 0.63; 95% CI, 0.46 to 0.87; P = 0.005). No new safety signals were observed, with no substantial between-group differences in quality-of-life measures. CONCLUSIONS: In patients with prostate cancer with high-risk biochemical recurrence, enzalutamide plus leuprolide was superior to leuprolide alone with respect to metastasis-free survival; enzalutamide monotherapy was also superior to leuprolide alone. The safety profile of enzalutamide was consistent with that shown in previous clinical studies, with no apparent detrimental effect on quality of life.

Niraparib with Abiraterone Acetate and Prednisone for Metastatic Castration-Resistant Prostate Cancer: Phase II QUEST Study Results.

Niraparib (NIRA) is a highly selective inhibitor of poly (adenosine diphosphate-ribose) polymerase, PARP1 and PARP2, which play a role in DNA repair. The phase II QUEST study evaluated NIRA combinations in patients with metastatic castration-resistant prostate cancer who were positive for homologous recombination repair gene alterations and had progressed on 1 prior line of novel androgen receptor-targeted therapy. Results from the combination of NIRA with abiraterone acetate plus prednisone, which disrupts androgen axis signaling through inhibition of CYP17, showed promising efficacy and a manageable safety profile in this patient population.

Early patient experience following treatment with the UroLift prostatic urethral lift and Rezum steam injection.

INTRODUCTION: To report the early postoperative patient experience, including symptom response, catheterization, recovery and satisfaction, following treatment with two minimally invasive surgical therapies (MIST) for benign prostatic hyperplasia (BPH): mechanical disobstruction with UroLift prostatic urethral lift (PUL) and tissue ablation with steam injection (Rezum). MATERIALS AND METHODS: Patient reported outcomes of 53 non-retention patients from two U.S. sites patients who underwent PUL (n = 30) or Rezum (n = 23) were collected within 2 months post-treatment. There were no exclusion criteria for baseline symptoms, prostate size, or BPH medical therapy. Patients completed questionnaires which assessed postoperative BPH symptoms and characteristics. Outcomes were compared between treatment arms with unpaired t-tests and Fisher's exact tests. RESULTS: PUL and Rezum patients were similar in age and prostate volume; patients completed the questionnaire an average of 30 ± 11 days post-treatment. Absolute mean International Prostate Symptom Score and quality of life was significantly better for PUL patients. Seven percent of PUL patients were catheterized by postoperative day 3 compared to 55% of Rezum patients (p = 0.0003). PUL patients experienced a rate of 83% treatment satisfaction (versus 65% for Rezum, p = 0.2) and less interference with daily activities (sports interference, p = 0.007; entertainment interference, p = 0.01; community interference, p = 0.04). Both groups reported BPH medication use following treatment (37% PUL versus 91% Rezum), albeit significantly higher for Rezum (p < 0.0001). CONCLUSION: Preliminary data suggests UroLift PUL provides a superior patient experience with better sexual function, lower catheterization rates, less daily interference, and higher patient satisfaction in the recovery period compared to Rezum.

Real-world outcomes of sipuleucel-T treatment in PROCEED, a prospective registry of men with metastatic castration-resistant prostate cancer.

BACKGROUND: The large registry, PROVENGE Registry for the Observation, Collection, and Evaluation of Experience Data (PROCEED)(NCT01306890), evaluated sipuleucel-T immunotherapy for asymptomatic/minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). METHODS: PROCEED enrolled patients with mCRPC receiving 3 biweekly sipuleucel-T infusions. Assessments included overall survival (OS), serious adverse events (SAEs), cerebrovascular events (CVEs), and anticancer interventions (ACIs). Follow-up was for ≥3 years or until death or study withdrawal. RESULTS: In 2011-2017, 1976 patients were followed for 46.6 months (median). The median age was 72 years, and the baseline median prostate-specific antigen level was 15.0 ng/mL; 86.7% were white, and 11.6% were African American. Among the patients, 1902 had 1 or more sipuleucel-T infusions. The median OS was 30.7 months (95% confidence interval [CI], 28.6-32.2 months). Known prognostic factors were independently associated with OS in a multivariable analysis. Among the 1255 patients who died, 964 (76.8%) died of prostate cancer (PC) progression. The median time from the first infusion to PC death was 42.7 months (95% CI, 39.4-46.2 months). The incidence of sipuleucel-T-related SAEs was 3.9%. The incidence of CVEs was 2.8%, and the rate per 100 person-years was 1.2 (95% CI, 0.9-1.6). The CVE incidence among 11,972 patients with mCRPC from the Surveillance, Epidemiology, and End Results-Medicare database was 2.8%; the rate per 100 person-years was 1.5 (95% CI, 1.4-1.7). One or more ACIs (abiraterone, enzalutamide, docetaxel, cabazitaxel, or radium 223) were received by 77.1% of the patients after sipuleucel-T; 32.5% and 17.4% of the patients experienced 1- and 2-year treatment-free intervals, respectively. CONCLUSIONS: PROCEED provides contemporary survival data for sipuleucel-T-treated men in a real-world setting of new life-prolonging agents, which will be useful in discussing treatment options with patients and in powering future trials with sipuleucel-T. The safety and tolerability of sipuleucel-T in PROCEED were consistent with previous findings.

24-month durability after crossover to the prostatic urethral lift from randomised, blinded sham.

OBJECTIVE: To evaluate the 24-month effectiveness of the prostatic urethral lift (PUL) procedure in men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) assessed through a crossover study. PATIENTS AND METHODS: In all, 53 patients underwent a sham procedure as part of the blinded, randomised L.I.F.T. (Luminal Improvement Following prostatic Tissue approximation for the treatment of LUTS secondary to BPH) study at 19 centres and elected to enrol in this crossover study. The crossover procedure involved placement of permanent implants (UroLift® system) into the prostatic lateral lobes. Patients were followed for 3 months after the sham procedure and then for 24 months after crossover to PUL, with assessments of urinary symptom relief, quality of life (QoL), urinary flow rate, sexual function, and adverse events. RESULTS: At 24 months after crossover to PUL, the International Prostate Symptom Score (IPSS), QoL, BPH Impact Index, and maximum urinary flow rate improved 36%, 40%, 54%, and 77% from baseline, respectively. Each IPSS parameter on average improved significantly from baseline (P < 0.005) and remained stable throughout follow-up. Symptom response after the sham procedure indicated initial improvement at 1 month with significant decay by 3 months. Adverse events were typically mild to moderate and patients returned rapidly to normal activity. Four patients (8%) required intervention with transurethral resection of the prostate and one patient required additional PUL implants within the 24-month period. There were no reported instances of de novo sustained erectile or ejaculatory dysfunction. CONCLUSIONS: The PUL procedure is associated with rapid symptom relief, increased urinary flow rate and QoL improvement that remain stable over 24 months. Morbidity is low and sexual function is preserved.

Multicentre prospective crossover study of the 'prostatic urethral lift' for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia.

OBJECTIVE: To assess the clinical effect of the 'prostatic urethral lift' (PUL) on lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) through a crossover design study. PATIENTS AND METHODS: Men aged ≥ 50 years with an International Prostate Symptom Score of ≥ 13, a maximum urinary flow rate (Qmax) of ≤ 12 mL/s, and a prostate of 30-80 mL were enrolled into a crossover study after completing a prospective, randomised, controlled, 'blinded' pivotal study in which they were control subjects receiving a sham procedure. Patients were followed for 1 year after crossover PUL at 19 centres in the USA, Canada and Australia. The sham procedure involved rigid cystoscopy with simulated active treatment sounds. PUL involved placing permanent UroLift® (NeoTract, Inc., Pleasanton, CA, USA) implants into the lateral lobes of the prostate to enlarge the urethral lumen. Urinary symptom relief, health-related quality of life (HRQL) impact, urinary flow parameters, sexual function, and adverse events were assessed and compared between the sham and PUL using paired statistical analysis. RESULTS: Symptom, flow, HRQL and sexual function assessments showed response improvements from baseline results, similar to results from other published studies, and most parameters were markedly improved after PUL vs the sham procedure in the same patients. Symptom, flow, and HRQL improvements were durable over the 12 months of the study. Adverse events associated with the procedure were typically transient and mild to moderate; one patient (2%) required re-intervention with transurethral resection of the prostate in the first year. There were no occurrences of de novo, sustained ejaculatory or erectile dysfunction. CONCLUSION: The PUL can be performed under local anaesthesia, causes minimal associated perioperative complications, allows patients to quickly return to normal activity, provides rapid and durable improvement in symptoms, and preserves sexual function.

Transurethral Vapor Ablation in Patients with Intermediate-Risk Localized Prostate Cancer.

Purpose: We report results of a prospective, multicenter single-arm study of transurethral vapor ablation (TUVA) of prostate tissue in patients with unilateral, intermediate-risk, localized prostate cancer (PCa). Materials and Methods: Men ≥45 years of age with biopsy-confirmed unilateral Gleason grade group 2 (GGG2) adenocarcinoma of the prostate, prostate volume of 20-80 cc, and prostate-specific antigen (PSA) ≤15 ng/mL were enrolled. Cystoscopy and transrectal ultrasound (TRUS) guidance were used to deliver ∼103°C water vapor to prostate zones for unilateral hemigland ablation, including destruction of cancers detected by multiparametric MRI (mpMRI) and confirmed by biopsy. The primary outcomes were device-related serious adverse events (SAEs). At 7 days and 6 months postprocedure, the ablation extent was assessed by mpMRI; MRI/TRUS fusion biopsies were completed at 6 months. Quality of life (QOL) was assessed with validated questionnaires. Results: All subjects underwent a single hemigland TUVA procedure. No SAEs occurred. Grade 2 procedure-related AEs included transient urinary retention (n = 4) and erectile (n = 1) or ejaculatory dysfunction (n = 1). At 7 days, mpMRI revealed complete ablation of 14/17 (82%) visible lesions. At 6 months, biopsies showed no Gleason pattern ≥4 or ≥GGG2 cancer on the treated side of prostates in 13/15 (87%) subjects. Ten of 15 (67%) subjects were biopsy negative. Of the 5 biopsy-negative subjects, 2 had one core each of 3 + 4 disease and 3 had one core each of 3 + 3 disease with ≤5% involvement. Median prostate volume was reduced by 40.7% and PSA by 58%. Extensive QOL assessments showed, on average, no appreciable negative effects of treatment. Conclusions: Initial evidence suggests that TUVA is safe in men with intermediate-risk PCa. Preliminary results demonstrate the absence of ≥GGG2 disease on the treated side in 87% of men and a favorable QOL profile.

Enzalutamide and Quality of Life in Biochemically Recurrent Prostate Cancer.

BACKGROUND: EMBARK, a controlled trial reported elsewhere, showed enzalutamide plus leuprolide (combination) and enzalutamide monotherapy prolonged metastasis-free survival versus placebo plus leuprolide (alone) in patients with high-risk biochemically recurrent prostate cancer. Health-related quality of life was also analyzed but not reported. METHODS: In EMBARK, patients with biochemical recurrence (prostate-specific antigen doubling time of ≤9 months) were randomly assigned (1:1:1) to combination (n=355), leuprolide-alone (n=358), or enzalutamide monotherapy (n=355). In this article we provide the patient-reported outcomes (PROs) from EMBARK at baseline and every 12 weeks until metastasis or death. The key end point was time to first and confirmed clinically meaningful deterioration (TTFD/TTCD) in pain and health-related quality of life using four PRO measures and predefined thresholds. RESULTS: At baseline, all groups had high health-related quality of life. For worst pain, the median TTFD was 19.35 months with leuprolide alone, 13.93 months with combination (hazard ratio, 1.08; 95% confidence interval [CI], 0.89 to 1.30) and 16.59 months with monotherapy (hazard ratio, 1.09; 95% CI, 0.90 to 1.31). The median TTCD was 66.27 months with leuprolide alone, 80.00 months with combination (hazard ratio, 0.82; 95% CI, 0.65 to 1.04), and 60.91 months with monotherapy (hazard ratio, 1.02; 95% CI, 0.82 to 1.28). For Functional Assessment of Cancer Therapy­Prostate total score, the median TTFD was 11.10 months with leuprolide alone, 8.31 months with combination (hazard ratio, 1.14; 95% CI, 0.95 to 1.36), and 8.38 months with monotherapy (hazard ratio, 1.17; 95% CI, 0.98 to 1.39). The median TTCD was 36.53 months with leuprolide alone, 38.77 months with combination (hazard ratio, 1.04; 95% CI, 0.85 to 1.28), and 30.55 months with monotherapy (hazard ratio, 1.16; 95% CI, 0.95 to 1.41). CONCLUSIONS: The PROs from EMBARK show that both enzalutamide combination and monotherapy versus leuprolide alone, with oncologic benefits noted above, preserved high health-related quality of life in patients with high-risk biochemical recurrence of prostate cancer.

Open Label Phase II Study of Enzalutamide With Concurrent Administration of Radium 223 Dichloride in Patients With Castration-Resistant Prostate Cancer.

BACKGROUND: Numerous globally approved castration-resistant prostate cancer (CRPC) therapies are available. Enzalutamide and radium 223 (Ra 223) are approved for survival prolongation and ability to delay radiographic progression. Both have markedly different mechanisms of action as well as safety and tolerability profiles. We prospectively investigated their combined safety and tolerability. PATIENTS AND METHODS: EnzaRadiCate, a phase II investigator-initiated trial, enrolled subjects with metastatic CRPC from 4 United States uro-oncology research sites. Safety assessment included physical examination, Eastern Cooperative Oncology Group status, electrocardiogram results, laboratory values, opioid use, radiographic responses, and adverse events (AEs). Quality of life and pain were assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) and the Brief Pain Inventory Short Form (BPI-SF) questionnaires. RESULTS: Thirty-nine subjects completed at least 2 cycles of Ra 223, and 34 (87%) completed all 6 cycles through and the EOT visit. Sixty-one treatment-related AEs were reported by 53.8% of subjects. The most frequent AEs were fatigue (25.6%), nausea (17.9%), and anemia (12.8%). Three subjects experienced non-treatment-related serious AEs. One subject was hospitalized for sepsis, and 2 deaths were attributed to disease progression. Fifteen (38.5%) subjects demonstrated radiographic progression, and 24 (61.5%) subjects had no radiographic progression. CONCLUSIONS: Safety and tolerability of combinatorial use of enzalutamide and Ra 223 were demonstrated. Subjects experienced improvements in quality of life and pain, without unexpected toxicities nor increases in falls, fractures, or deaths. Phase III combination trials of Ra 223 with novel oral hormonal agents are ongoing to further evaluate radiographic progression and overall survival benefit.

Survival of African-American and Caucasian men after sipuleucel-T immunotherapy: outcomes from the PROCEED registry.

PURPOSE: African Americans experience greater prostate cancer risk and mortality than do Caucasians. An analysis of pooled phase III data suggested differences in overall survival (OS) between African American and Caucasian men receiving sipuleucel-T. We explored this in PROCEED (NCT01306890), an FDA-requested registry in over 1900 patients with metastatic castration-resistant prostate cancer (mCRPC) treated with sipuleucel-T. PATIENTS AND METHODS: OS for patients who received ≥1 sipuleucel-T infusion was compared between African American and Caucasian men using an all patient set and a baseline prostate-specific antigen (PSA)-matched set (two Caucasians to every one African American with baseline PSAs within 10% of each other). Univariable and multivariable analyses were conducted. Survival data were examined using Kaplan-Meier and Cox proportional hazard methodologies. RESULTS: Median follow-up was 46.6 months. Overall survival differed between African American and Caucasian men with hazard ratios (HR) of 0.81 (95% confidence interval [CI]: 0.68-0.97, P = 0.03) in the all patient set and 0.70 (95% CI: 0.57-0.86, P < 0.001) in the PSA-matched set. Median OS was longer in African Americans than in Caucasian men for both analysis sets, e.g., 35.3 and 25.8 months, respectively, in the PSA-matched set. Similar results were observed in the all patient set. Differences were larger when treatment began at lower baseline PSA; curves were more similar among patients with higher baseline PSA. In patients with baseline PSA below the median, the HR was 0.52 (95% CI: 0.37-0.72, P < 0.001), with median OS of 54.3 versus 33.4 months. Known prognostic factors and African American race (multivariable analyses; HR: 0.60, 95% CI: 0.48-0.74, P < 0.001) were independently associated with OS. Use of post-sipuleucel-T anticancer interventions was balanced between races. CONCLUSION: In this exploratory analysis of a registry including nearly 12% African American men with mCRPC, OS was significantly different between African Americans and Caucasians, indicating further research is warranted.

eRADicAte: A Prospective Evaluation Combining Radium-223 Dichloride and Abiraterone Acetate Plus Prednisone in Patients With Castration-Resistant Prostate Cancer.

BACKGROUND: Multiple castration-resistant prostate cancer (CRPC) therapies are approved by the United States Food and Drug Administration. Radium-223 dichloride (Ra-223) with abiraterone acetate plus prednisone have different mechanisms of action and distinct off-target side-effect profiles. We prospectively investigated their combined safety, tolerability, and patient-reported outcome measures. PATIENTS AND METHODS: eRADicAte, an investigator-initiated, phase II trial, studied 31 patients with metastatic CRPC, from 5 United States uro-oncology research sites. Patients completed 6 cycles of Ra-223 with concurrent abiraterone therapy. Quality of life and pain were assessed using the Functional Assessment of Cancer Therapy-Prostate and the Brief Pain Inventory-Short Form questionnaires and their subscales; we reported the number of subjects meeting standardized criteria for clinically meaningful improvements on each scale. Safety assessment included Eastern Cooperative Oncology Group performance status, laboratory changes, opioid use, radiographic responses, and adverse events (AEs). RESULTS: Twenty of 31 (65%) experienced positive clinically meaningful improvement changes on the Functional Assessment of Cancer Therapy-Prostate, and 25 (81%) of 31 on the Prostate Cancer Subscale. Eighteen (58%) of 31 demonstrated reduced pain intensity and 12 (39%) of 31 demonstrated reduction of pain interference in their lives. At baseline, subjects averaged 11.6 ± 2.8 bone lesions; at the end of treatment, subjects averaged 5.6 ± 2.4 bone lesions (P = .0002). The most frequent AEs were diarrhea (17%), nausea (17%), and fatigue (14%). There were 6 serious AEs; 1 led to study withdrawal. CONCLUSIONS: Patients experienced clinically meaningful improvements in quality of life and pain, without unexpected adverse toxicities. Phase III combination trials of Ra-223 with novel oral hormonal agents are ongoing to further evaluate radiographic progression and overall survival benefit.

Clinical utility of the Prostate Health Index (phi) for biopsy decision management in a large group urology practice setting.

BACKGROUND: Deciding when to biopsy a man with non-suspicious DRE findings and tPSA in the 4-10 ng/ml range can be challenging, because two-thirds of such biopsies are typically found to be benign. The Prostate Health Index (phi) exhibits significantly improved diagnostic accuracy for prostate cancer detection when compared to tPSA and %fPSA, however only one published study to date has investigated its impact on biopsy decisions in clinical practice. METHODS: An IRB approved observational study was conducted at four large urology group practices using a physician reported two-part questionnaire. Physician recommendations were recorded before and after receiving the phi test result. A historical control group was queried from each site's electronic medical records for eligible men who were seen by the same participating urologists prior to the implementation of the phi test in their practice. 506 men receiving a phi test were prospectively enrolled and 683 men were identified for the historical control group (without phi). Biopsy and pathological findings were also recorded for both groups. RESULTS: Men receiving a phi test showed a significant reduction in biopsy procedures performed when compared to the historical control group (36.4% vs. 60.3%, respectively, P < 0.0001). Based on questionnaire responses, the phi score impacted the physician's patient management plan in 73% of cases, including biopsy deferrals when the phi score was low, and decisions to perform biopsies when the phi score indicated an intermediate or high probability of prostate cancer (phi ≥36). CONCLUSIONS: phi testing significantly impacted the physician's biopsy decision for men with tPSA in the 4-10 ng/ml range and non-suspicious DRE findings. Appropriate utilization of phi resulted in a significant reduction in biopsy procedures performed compared to historical patients seen by the same participating urologists who would have met enrollment eligibility but did not receive a phi test.

Safety and Antitumor Activity of Apalutamide (ARN-509) in Metastatic Castration-Resistant Prostate Cancer with and without Prior Abiraterone Acetate and Prednisone.

Purpose: To evaluate the efficacy of apalutamide before or after treatment with abiraterone acetate and prednisone (AAP) in patients with progressive metastatic castration-resistant prostate cancer (mCRPC).Experimental Design: Two cohorts were studied: AAP-naïve and post-AAP patients who had received ≥6 months of AAP. Patients had progressive mCRPC per rising prostate-specific antigen (PSA) and/or imaging, without prior chemotherapy exposure. All received apalutamide 240 mg/day. Primary endpoint was ≥50% decline in 12-week PSA according to Prostate Cancer Working Group 2 criteria. Secondary endpoints included time to PSA progression and time on treatment.Results: Forty-six patients enrolled in the AAP-naïve (n = 25) and post-AAP (n = 21) cohorts. The 12-week PSA response rate was 88% (22/25) and 22% (4/18), median time to PSA progression was 18.2 months [95% confidence interval (CI), 8.3 months-not reached) and 3.7 months (95% CI, 2.8-5.6 months), and median time on treatment 21 months (range, 2.6-37.5) and 4.9 months (range, 1.3-23.2), for the AAP-naïve and post-AAP cohorts, respectively. Eighty percent (95% CI, 59-93) and 64% (95% CI, 43-82) of AAP-naïve and 43% (95% CI, 22-66) and 10% (95% CI, 1-30) of post-AAP patients remained on treatment for 6+ and 12+ months, respectively. Common treatment-emergent adverse events in both cohorts were grade 1 or 2 fatigue, diarrhea, nausea, and abdominal pain.Conclusions: Apalutamide was safe, well tolerated, and demonstrated clinical activity in mCRPC, with 80% of AAP-naïve and 43% of post-AAP patients, remaining on treatment for 6 months or longer.

Use of intravesical valrubicin in clinical practice for treatment of nonmuscle-invasive bladder cancer, including carcinoma in situ of the bladder.

OBJECTIVES: The objective was to conduct a US multicenter, retrospective medical record study examining the effectiveness, safety, and patterns of use of valrubicin for treatment of nonmuscle-invasive bladder cancer (NMIBC) by clinicians since the 2009 reintroduction of valrubicin. METHODS: Patients ≥ 18 years with NMIBC who received had one or more instillations of valrubicin (October 2009- September 2011) were eligible. The primary endpoint was event-free survival (EFS). Safety and tolerability were also assessed. RESULTS: The medical records of 113 patients met the inclusion criteria; 100 patients (88.5%) completed valrubicin treatment. The median age was 75 years (range 42-95 years). The median NMIBC duration was 31 months since diagnosis: 51.3% (58/113) had carcinoma in situ (CIS) alone, and 31.9% (36/113) had unspecified NMIBC. Most patients, 94.7% (107/113), had more than three valrubicin instillations and 70.8% (80/113) completed a full course. The EFS rate (95% confidence interval) was 51.6% (40.9-61.3%), 30.4% (20.4-41.1%), and 16.4% (7.9-27.5%) at 3, 6, and 12 months, respectively. Median time to an event was 3.5 (2.5-4.0) months after the first valrubicin instillation. Local adverse reactions (LARs) were experienced by 49.6% (56/113) of patients; most LARs were mild (93.6%). The most frequent LARs were hematuria, pollakiuria, micturition urgency, bladder spasm, and dysuria. In total, 4.4% (5/113) of patients discontinued valrubicin because of adverse events or LARs. CONCLUSIONS: Data from the present retrospective study are consistent with previous prospective clinical trials that demonstrated valrubicin effectiveness and tolerability for select patients with CIS, before considering cystectomy. Additional prospective studies are warranted to evaluate valrubicin safety and efficacy in the broader patient population with NMIBC.

Prostate cancer in men using testosterone supplementation.

PURPOSE: Although an association between testosterone supplementation and the development of prostate cancer is unproven, a recent increase in the use of this therapy has reopened the debate about its safety in men at risk for prostate cancer. To increase awareness of this risk, we report on a series of patients in whom clinically significant prostate cancer developed and was presumed to be related to exogenous testosterone use. MATERIALS AND METHODS: The medical records of 6 urology practices were reviewed to identify men undergoing testosterone supplementation for sexual dysfunction or "rejuvenation " who were found to have prostate cancer after initiation of exogenous testosterone supplementation. Cases were analyzed to determine clinical and pathological parameters characterizing the presentation of prostate cancer. RESULTS: A total of 20 men were diagnosed with prostate cancer after initiation of testosterone therapy. Prostate cancer was detected within 2 years of testosterone initiation in 11 men (55%) and from 28 months to 8 years in the remainder. The tumors were of moderate and high grade, being Gleason sum 6, 7 and 8 to 10 in 9 (45%), 6 (30%) and 5 (25%) men, respectively. Median serum prostate specific antigen (PSA) concentration at diagnosis tended to be low at 5.1 ng/ml (range 1.1 to 329.0) and digital rectal examination generally proved more sensitive than PSA assays in detecting the cancer. Patients seen by nonurologist physicians were monitored less often for prostate cancer during testosterone use than those followed by urologists. CONCLUSIONS: Prostate cancer may become clinically apparent within months to a few years after the initiation of testosterone treatment. Digital rectal examination is particularly important in the detection of these cancers. Physicians prescribing testosterone supplementation and patients receiving it should be cognizant of this risk, and serum PSA testing and digital rectal examination should be performed frequently during treatment.

Acute renal failure caused by complete bladder eversion through a vesicovaginal fistula.

We report a rare case of bladder eversion through a vesicovaginal fistula. The bladder prolapse was almost complete, resulting in ureteral kinking, bilateral hydronephrosis and acute renal failure. After reduction of the bladder eversion, bilateral ureteral stent placement, fistula repair using the Latzko technique and colpocleisis, the patient had rapid resolution of her renal compromise.
