A phase II trial of apalutamide for intermediate-risk prostate cancer and molecular correlates.

OBJECTIVES: To determine whether 6 months of preoperative apalutamide for intermediate-risk prostate cancer (IRPCa) reduces the aggregate postoperative radiotherapy risk and to evaluate associations of molecular perturbations with clinical outcomes in this study cohort. PATIENTS AND METHODS: Between May 2018 and February 2020, eligible patients with IRPCa (Gleason 3 + 4 or 4 + 3 and clinical T2b-c or prostate-specific antigen level of 10-20 ng/mL) were treated with apalutamide 240 mg/day for 6 months followed by radical prostatectomy (RP) in this single-arm, phase II trial. The primary endpoint was presence of any adverse pathological feature at risk of pelvic radiation (pathological T stage after neoadjuvant therapy [yp]T3 or ypN1 or positive surgical margins). Translational studies, including germline and somatic DNA alterations and RNA and protein expression, were performed on post-apalutamide RP specimens, and assessed for associations with clinical outcomes. RESULTS: A total of 40 patients underwent a RP, and only one patient discontinued apalutamide prior to 6 months. In all, 40% had adverse pathological features at time of RP, and the 3-year biochemical recurrence (BCR) rate was 15%, with 27.5% being not evaluable. Genomic alterations frequently seen in metastatic PCas, such as androgen receptor (AR), tumour protein p53 (TP53), phosphatase and tensin homologue (PTEN), or BReast CAncer associated gene (BRCA1/2) were underrepresented in this localised cohort. Adverse pathological features and BCR at 3-years were associated with increased expression of select cell cycle (e.g., E2F targets: adjusted P value [Padj] < 0.001, normalised enrichment score [NES] 2.47) and oxidative phosphorylation (Padj < 0.001, NES 1.62) pathways. CONCLUSIONS: Preoperative apalutamide did not reduce the aggregate postoperative radiation risk to the pre-specified threshold in unselected men with IRPCa. However, transcriptomic analysis identified key dysregulated pathways in tumours associated with adverse pathological outcomes and BCR, which warrant future study. Further investigation of preoperative therapy is underway for men with high-risk PCa.

Long-Term Outcomes of Whole Gland Salvage Cryotherapy for Locally Recurrent Prostate Cancer following Radiation Therapy: A Combined Analysis of Two Centers.

PURPOSE: Radiation refractory prostate cancer (RRPCa) is common and salvage cryotherapy for RRPCa is emerging as a viable local treatment option. However, there is a paucity of long-term data. The purpose of this study is to determine long-term outcomes following salvage cryotherapy for RRPca. MATERIALS AND METHODS: Patients undergoing salvage cryotherapy for biopsy-proven, localized RRPCa from 1992 through 2004 were prospectively accrued at two centers. Preoperative characteristics, perioperative morbidity and postoperative data were reviewed from our database. The primary outcomes were overall survival (OS) and disease-specific survival (DSS). The secondary outcomes were freedom from castration-resistant prostate cancer (CRPC) and freedom from androgen deprivation therapy (ADT). RESULTS: A total of 268 patients were identified with a median followup of 10.3 years. A total of 223 complication events were recorded; of them, 168 were Clavien I-II events and 55 Clavien III events. At 10 years, 69% had freedom from ADT and 76% had freedom from CRPC. The 10-year DSS rate was 81%, and the 10-year OS rate was 77%. A pre-salvage prostate specific antigen level of >10 ng/ml was associated with an increased risk of developing CRPC and initiation of ADT but was not associated with DSS or OS. The use of neoadjuvant ADT was associated with improved OS and DSS but did not affect freedom from CRPC or adjuvant ADT. CONCLUSIONS: Salvage cryotherapy for RRPCa provides excellent long-term freedom from ADT, CRPC and DSS with acceptable morbidity. OS at 10 years was 77%. Prospective trials are required for validation.

Prospective trial of regional (hockey-stick) prostate cryoablation: oncologic and quality of life outcomes.

PURPOSE: To report long-term follow-up of the efficacy of subtotal prostate ablation using a "hockey-stick" template, including oncologic control and quality of life (QoL) impact. METHODS: We performed a prospective controlled trial to evaluate the efficacy of subtotal prostate ablation in selected men with baseline and confirmatory biopsy showing grade group (GG) 1-2 prostate cancer. "Hockey-stick" cryoablation that included the ipsilateral hemi-gland and contralateral anterior prostate was performed. Prostate biopsies and QOL queries were performed at 6, 18 and 36 months following regional ablation, and follow-up was updated to include subsequent clinic visits. RESULTS: Between August 2009 and January 2012, 72 men were screened for eligibility and 47 opted to undergo confirmatory biopsy. Of these, 23 were deemed eligible and treated with regional cryoablation. Median age was 64 years. Median follow-up was 74 months. A single patient had < 1 mm of in-field viable tumor with therapy effect on 36-month biopsy. At time of last follow-up, a total of 12/23 (52%) patients did not have evidence of disease, all patients had preserved urinary control with no patients requiring pads for urinary incontinence. Sexual decline was significant at 3 and 6 months (P < 0.01 for both), though improvement was seen at subsequent time points. CONCLUSION: Subtotal (hockey-stick template) cryoablation of the prostate provides oncologic control to targeted tissue in a generally low-risk group with minimal impact on sexual and urinary function. Further studies are needed to evaluate this ablation template in the MRI-targeted era and higher risk populations.

Patterns of metastases of prostatic ductal adenocarcinoma.

BACKGROUND: The current study was conducted to investigate the patterns of metastases in men with metastatic prostatic ductal adenocarcinoma (DAC) and recurrence patterns after therapy. METHODS: All patients with a new diagnosis of DAC with de novo metastases and those with localized disease who developed metastases after treatment and were treated at the study institution from January 2005 to November 2018 were included. All patient and tumor characteristics and outcome data were collected. RESULTS: A total of 164 patients (37.7%) had metastatic DAC, including 112 with de novo metastases and 52 who developed metastases after treatment. Men with de novo metastases were found to have a significantly higher median prostate-specific antigen level and International Society of Urological Pathology grade but a lower cT3 and/or T4 classification compared with those with metastases that developed after treatment (all P < .05). Approximately 87% of men with de novo metastases progressed despite multiple systemic therapies, 37.6% required intervention for the palliation of symptoms, and 10.1% responded to systemic therapy and underwent treatment of the primary tumor. Men with de novo metastatic DAC and those who developed metastases after treatment had multiple metastatic sites (including bone and viscera), with higher rates of lung metastases noted in the posttreatment group (23.2% vs 44.2%; P = .01). A total of 45 patients who were treated with curative intent developed metastases at a median of 22 months (range, 0.9-74.8 months) after treatment, at low prostate-specific antigen levels (median, 4.4 ng/mL [interquartile range, 1.7-11.1 ng/mL]). CONCLUSIONS: The current study described the metastatic patterns of DAC in both patients with de novo metastatic disease and those who later progress to metastases. Men receiving treatment for DAC with curative intent require stringent long-term follow-up with imaging modalities, including chest imaging given the predilection toward lung metastases noted among these patients.

Intraoperative and early postoperative complications in postchemotherapy retroperitoneal lymphadenectomy among patients with germ cell tumors using validated grading classifications.

BACKGROUND: Postchemotherapy retroperitoneal lymphadenectomy (PC-RPLND) is an essential, yet potentially morbid, therapy for the management of patients with advanced germ cell tumors. In the current study, the authors sought to define the complication profile of PC-RPLND using validated grading systems for intraoperative adverse events (iAEs) and early postoperative complications. METHODS: Between 2000 and 2018, all patients who underwent PC-RPLND were analyzed for iAEs and early postoperative complications using the Kaafarani and Clavien-Dindo classifications, respectively. Logistic regression models were conducted to assess patient and tumor factors associated with iAEs and postoperative complications. RESULTS: Of the 453 patients identified, 115 patients (25%) and 252 patients (56%), respectively, experienced an iAE and postoperative complication. Major iAEs (grade ≥3) were observed in 15 patients (3%) and major postoperative complications (grade ≥3) were noted in 80 patients (18%). The most common iAE was vascular injury (112 of 132 events; 85%), which occurred in 92 patients (20%), and the most frequent postoperative complication was ileus, which occurred in 121 patients (27%). Original and postchemotherapy retroperitoneal mass size, nonretroperitoneal metastases, intermediate and/or poor International Germ Cell Cancer Collaborative Group classification, previous RPLND, elevated tumor markers at the time of RPLND, and anticipated adjuvant surgical procedures increased the risk of both iAEs and postoperative complications. Patients who experienced an iAE were significantly more likely to experience a postoperative complication (odds ratio, 2.50; 95% confidence interval, 1.58-3.97 [P < .001]). CONCLUSIONS: In what to the authors' knowledge is the first analysis of PC-RPLND using validated classifications for both iAEs and postoperative complications, advanced disease and surgical complexity significantly increased the risks of major iAEs and postoperative complications. Standardized reporting of adverse perioperative events allows providers and patients to appreciate the consequences of PC-RPLND during counseling and decision making.

Contemporary prostate cancer treatment choices in multidisciplinary clinics referenced to national trends.

BACKGROUND: The purpose of this study was to assess treatment choices among men with prostate cancer who presented at The University of Texas MD Anderson Cancer Center multidisciplinary (MultiD) clinic compared with nationwide trends. METHODS: In total, 4451 men with prostate cancer who presented at the MultiD clinic from 2004 to 2016 were analyzed. To assess nationwide trends, the authors analyzed 392,710 men with prostate cancer who were diagnosed between 2004 and 2015 from the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoint was treatment choice as a function of pretreatment demographics. RESULTS: Univariate analyses revealed similar treatment trends in the MultiD and SEER cohorts. The use of procedural forms of definitive therapy decreased with age, including brachytherapy and prostatectomy (all P < .05). Later year of diagnosis/clinic visit was associated with decreased use of definitive treatments, whereas higher risk grouping was associated with increased use (all P < .001). Patients with low-risk disease treated at the MultiD clinic were more likely to receive nondefinitive therapy than patients in SEER, whereas the opposite trend was observed for patients with high-risk disease, with a substantial portion of high-risk patients in SEER not receiving definitive therapy. In the MultiD clinic, African American men with intermediate-risk and high-risk disease were more likely to receive definitive therapy than white men, but for SEER the opposite was true. CONCLUSIONS: Presentation at a MultiD clinic facilitates the appropriate disposition of patients with low-risk disease to nondefinitive strategies of patients with high-risk disease to definitive treatment, and it may obviate the influence of race.

The role of metastatic burden in cytoreductive/consolidative radical cystectomy.

PURPOSE: To describe our institutional experience with cytoreductive/consolidative radical cystectomy (CCRC) for metastatic urothelial carcinoma (UC) and to investigate clinicopathologic features predicting prolonged cancer specific survival (CSS) following CCRC. METHODS: We performed IRB-approved review of our cystectomy database, and identified 43 patients with metastatic UC who underwent CCRC. Baseline demographics, chemotherapy regimen, clinicopathologic features, and perioperative complications were collected. Progression-free survival (PFS) and CSS were estimated from the time of CCRC. Univariate and multivariate Cox regression models were used to identify predictors of improved CSS after CCRC. RESULTS: Of the 43 patients, 32 (74.4%) had clinical evidence of distant metastases, while 11 harbored occult metastases on the surgical specimen. The most common site of metastasis was the retroperitoneal lymph nodes, found in 30 patients. Solitary metastases were found in 22 patients (51.1%). Forty-one (95%) patients received chemotherapy prior to CCRC. Disease progression was detected in 35 patients after CCRC (median PFS 5.9 months), and 34 died of metastatic cancer (median CSS 12.3 months). On multivariate analysis, patients with solitary metastases were found to have improved CSS compared to those with multiple metastases (HR 2.62, 95% CI 1.16-5.90, p = 0.02), with median CSS of 26.0 months vs. 7.9 months (p < 0.001). Median postoperative length of stay was 10 days. Overall, 56% suffered postoperative complications, including one perioperative mortality. CONCLUSIONS: CCRC is feasible in the setting of metastatic UC. Patients with solitary metastasis demonstrated longer CSS than those with multiple metastases, and should be considered candidates for future trials evaluating the role of CCRC for metastatic UC.

Managing seminomatous and nonseminomatous germ cell tumors.

PURPOSE OF REVIEW: In the present review, we summarize the recent developments in the management of germ cell tumors (GCTs). RECENT FINDINGS: Treatment-related acute and late-onset toxicity remains a key challenge in the management of GCTs, with recent evidence showing that the adverse health outcomes of etoposide and cisplatin for four cycles in comparison to bleomycin, etoposide, and cisplatin for three cycles appear to be similar. Recent data showed that multidisciplinary clinic approach and management in experienced academic centers were associated with improved overall survival in GCT patients. There are currently multiple conventional-dose chemotherapy options for salvage therapy in patients with refractory or recurrent disease. In addition, more efficacious high-dose chemotherapy regimens continue to be developed. The role of salvage conventional-dose chemotherapy versus high-dose chemotherapy is currently being investigated prospectively. Recent reports suggested that brentuximab vedotin could be a potential salvage option for cluster of differentiation 30 positive refractory GCTs. On the other hand the results of the first phase II clinical trial investigating pembrolizumab in refractory GCTs were disappointing showing no clinical activity.Finally, deep exploration of the immune profile of GCTs using immunohistochemistry and gene expression profiling has identified that advanced GCT stage was associated with decreased T-cell and Natural killer-cell signatures, whereas T regulatory, neutrophil, mast cell, and macrophage signatures increased with advanced stage. Even though these results indicated that activated T-cell infiltration correlated with seminoma histology and good prognosis, and could be used in the future as a biomarker, this approach needs to be validated in a large cohort. SUMMARY: Remaining challenges to be addressed include minimizing therapeutic toxicity, and improving outcomes in patients with refractory/recurrent GCTs.

Baseline and longitudinal plasma caveolin-1 level as a biomarker in active surveillance for early-stage prostate cancer.

OBJECTIVES: To evaluate the role of caveolin-1 (Cav-1) as a predictor of disease reclassification (DR) in men with early prostate cancer undergoing active surveillance (AS). PATIENTS AND METHODS: We analysed archived plasma samples prospectively collected from patients with early prostate cancer in a single-institution AS study. Of 825 patients enrolled, 542 had ≥1 year of follow-up. Baseline and longitudinal plasma Cav-1 levels were measured using an enzyme-linked immunosorbent assay. Tumour volume or Gleason grade increases were criteria for DR. Logistic regression analyses were used to assess associations between clinicopathological characteristics and reclassification risk. RESULTS: In 542 patients, 480 (88.6%) had stage cT1c disease, 542 (100.0%) had a median prostate-specific antigen level of 4.1 ng/mL, and 531 (98.0%) had a median Cancer of the Prostate Risk Assessment score of 1. In all, 473 (87.3%) had a Gleason score of 3+3. After a median of 3.1 years of follow-up, disease was reclassified in 163 patients (30.1%). The mean baseline Cav-1 level was 2.2 ± 8.5 ng/mL and the median 0.2 ng/mL (range, 0-85.5 ng/mL). In univariate analysis, baseline Cav-1 was a significant predictor for risk of DR (odds ratio [OR] 1.82, 95% confidence interval [CI] 1.24-2.65; P = 0.002). In multivariate analysis, with adjustments for age, tumour length, group risk stratification and number of positive cores, reclassification risk associated with Cav-1 remained significant (OR 1.91, 95% CI 1.28-2.84; P = 0.001). CONCLUSION: Baseline plasma Cav-1 level was an independent predictor of disease classification. New methods for refining AS and intervention may result.

Quality of life after brachytherapy or bilateral nerve-sparing robot-assisted radical prostatectomy for prostate cancer: a prospective cohort.

OBJECTIVE: To provide comparative data on quality of life (QoL) after prostate cancer treatment to help patients make an informed decision regarding their choice of treatment. METHODS: Patients with pathologically proven, non-metastatic, T1-T3bN0 prostate cancer were included in this prospective non-randomized study if they were to receive treatment with curative intent. Sample size was at least 181 patients per cohort/treatment type. QoL was recorded at baseline and at each follow-up using the Expanded Prostate Cancer Index Composite (EPIC) instrument. The minimal clinically important difference was defined as half of the standard deviation of the baseline score for each domain. A mixed effects model was used to compare the different treatments. Data are presented on the brachytherapy and the bilateral nerve-sparing robot-assisted radical prostatectomy (RARP) cohorts. Hormonotherapy was not allowed. RESULTS: Between November 2007 and January 2013, 181 patients who received brachytherapy and 210 patients who underwent RARP were included. Of the patients who underwent RARP, 178 had bilateral nerve-sparing and were included in the present analysis. Response rate to EPIC questionnaires were higher in the brachytherapy than in the RARP arm: 82% vs 57% at 2 years after treatment and 55% vs 45% at 4 years after treatment. In the mixed effects model, patients in the RARP arm had better QoL with regard to urinary irritation/obstruction or bother and bowel function, and lower QoL regarding sexual function and urinary incontinence. Results were confirmed in a propensity score-matched model. Patient satisfaction was significantly higher in the brachytherapy group at 1, 2 and 3 years after treatment. CONCLUSION: This prospective non-randomized study shows long-term differences in QoL domains after bilateral nerve-sparing RARP and brachytherapy. Differences in patient satisfaction should be further explored. These results could be used to counsel patients in the decision-making process.

Clinical risk stratification in patients with surgically resectable micropapillary bladder cancer.

OBJECTIVE: To analyse survival in patients with clinically localised, surgically resectable micropapillary bladder cancer (MPBC) undergoing radical cystectomy (RC) with and without neoadjuvant chemotherapy (NAC) and develop risk strata based on outcome data. PATIENTS AND METHODS: A review of our database identified 103 patients with surgically resectable (≤cT4acN0 cM0) MPBC who underwent RC. Survival estimates were calculated using Kaplan-Meier method and compared using log-rank tests. Classification and regression tree (CART) analysis was performed to identify risk groups for survival. RESULTS: For the entire cohort, estimated 5-year overall survival and disease-specific survival (DSS) rates were 52% and 58%, respectively. CART analysis identified three risk subgroups: low-risk: cT1, no hydronephrosis; high-risk: ≥cT2, no hydronephrosis; and highest-risk: cTany with tumour-associated hydronephrosis. The 5-year DSS for the low-, high-, and highest-risk groups were 92%, 51%, and 17%, respectively (P < 0.001). Patients down-staged at RC

Examination of moderators of expressive writing in patients with renal cell carcinoma: the role of depression and social support.

OBJECTIVE: To identify groups most likely to benefit from an Expressive Writing (EW) intervention, we examined psychosocial variables as intervention moderators. We hypothesized that EW would be particularly effective for participants with high levels of depressive symptoms and social support at study entry. METHODS: Patients (n = 277; 60.6% male) with kidney cancer were randomly assigned to either an expressive (EW) or neutral writing (NW) condition. Intervention outcomes included measures of depressive symptoms (CESD), cancer-related symptoms (MDASI), fatigue (BFI), and sleep disturbances (PSQI) assessed at baseline, 1, 4, and 10 months later. Moderators were measured at baseline. RESULTS: As hypothesized, depressive symptoms and social support moderated intervention efficacy. When examining both moderators simultaneously, EW appeared to be most effective in terms of cancer-related symptoms (p < 0.05) and depressive symptoms (p < 0.01) for participants with elevated depressive symptoms who received high levels of social support at baseline relative to their counterparts in the NW condition. Moreover, participants in EW with high levels of social support at baseline reported lower levels sleep disturbances (p = 0.005) than their counterparts in NW. CONCLUSIONS: Recognition of baseline depressive symptoms and social support as intervention moderators may lead to improved patient selection for EW interventions, as EW may be particularly beneficial regarding QOL outcomes for patients that have social support available including participants with depressive symptoms. EW may not be beneficial, or potentially even contraindicated, for participants lacking social support. Copyright © 2016 John Wiley & Sons, Ltd.

Intratumoral heterogeneity: Role of differentiation in a potentially lethal phenotype of testicular cancer.

BACKGROUND: Intratumoral heterogeneity presents a major obstacle to the widespread implementation of precision medicine. The authors assessed the origin of intratumoral heterogeneity in nonseminomatous germ cell tumor of the testis (NSGCT) and identified distinct tumor subtypes and a potentially lethal phenotype. METHODS: In this retrospective study, all consecutive patients who had been diagnosed with an NSGCT between January 2000 and December 2010 were evaluated. The histologic makeup of primary tumors and the clinical course of disease were determined for each patient. A Fine and Gray proportional hazards regression analysis was used to determine the prognostic risk factors, and the Gray test was used to detect differences in the cumulative incidence of cancer death. In a separate prospective study, next-generation sequencing was performed on tumor samples from 9 patients to identify any actionable mutations. RESULTS: Six hundred fifteen patients were included in this study. Multivariate analysis revealed that the presence of yolk sac tumor in the primary tumor (P = .0003) was associated with an unfavorable prognosis. NSGCT could be divided into 5 subgroups. Patients in the yolk sac-seminoma subgroup had the poorest clinical outcome (P = .0015). These tumors tended to undergo somatic transformation (P < .0001). Among the 9 NSGCTs that had a yolk sac tumor phenotype, no consistent gene mutation was detected. CONCLUSIONS: The current data suggest that intratumoral heterogeneity is caused in part by differentiation of pluripotent progenitor cells. Integrated or multimodal therapy may be effective at addressing intratumoral heterogeneity and treating distinct subtypes as well as a potentially lethal phenotype of NSGCT.

Disease reclassification risk with stringent criteria and frequent monitoring in men with favourable-risk prostate cancer undergoing active surveillance.

OBJECTIVES: To determine the frequency of disease reclassification and to identify clinicopathological variables associated with it in patients with favourable-risk prostate cancer undergoing active surveillance (AS). PATIENTS AND METHODS: We assessed 191 men, selected by what may be the most stringent criteria used in AS studies yet conducted, who were enrolled in a prospective cohort AS trial. Clinicopathological characteristics were analysed in a multivariate Cox proportional hazards regression model. Key features were an extended biopsy with a single core positive for Gleason score (GS) 3 + 3 (<3 mm) or 3 + 4 (<2 mm) and a prostate-specific antigen (PSA) level <4 ng/mL (adjusted for prostate volume). Biopsies were repeated every 1-2 years and clinical evaluations every 6 months. Disease was reclassified when PSA level increased by 30% from baseline, or when biopsy tumour length increased beyond the enrolment criteria, more than one positive core was detected or any grade increased to a dominant 4 pattern or any 5 pattern. RESULTS: Disease was reclassified in 32 patients (16.8%) including upgrading to GS 4 + 3 in five patients (2.6%). The median (interquartile range) follow-up time among survivors was 3 (1.9-4.6) years. Overall, 13 of the 32 (40.6%) had incremental increases in GS. Tumour length (hazard ratio 2.95, 95% confidence interval [CI] 1.34-6.46; P = 0.007) and older age (hazard ratio 1.05, 95% CI 1.00-1.09; P = 0.05) were identified as significant and marginally significant predictors of disease reclassification, respectively. Disease remained stable in 83.2% of patients. CONCLUSION: The need persists for improvements in risk stratification and predictive indicators of cancer progression.

Robotic-assisted laparoscopic versus open salvage radical prostatectomy following radiotherapy.

INTRODUCTION: To describe immediate perioperative outcomes of robot-assisted laparoscopic salvage radical prostatectomy for recurrent cancer following radiation therapy, and compare outcomes to a contemporary open surgical cohort. MATERIALS AND METHODS: A total of 39 patients underwent salvage radical prostatectomy with pelvic lymphadenectomy (20 robotic, 19 open) for local recurrence following radiation therapy at a single institution between 2007 and 2011. Intraoperative parameters, postoperative complications, and oncological outcomes, were recorded. Wilcoxon rank-sum test and Fisher's exact test were used for comparison of continuous and categorical variables respectively. Mean values of numeric variables are reported with standard deviation. RESULTS: The cohorts were similar with respect to age, ethnicity, and American Society of Anesthesiologists Score classification. Estimated blood loss was lower in the robotic group versus the open group (381.3 mL versus 865.0 mL, p = 0.001). There was no difference in the rate of intraoperative complications, postoperative Clavien = 3 complications (30% versus 15.7%), anastomotic leak (40% versus 42.1%), or wound infection (0% versus 15.7%) in the robotic and open groups. Mean node yield (10.4 versus 11.8), positive surgical margins (15.0% versus 15.7%), and undetectable prostate-specific antigen rate (78% versus 60%) were also similar between the robotic and open groups. CONCLUSIONS: Robotic salvage prostatectomy appears to have no significant difference to the open approach with respect to safety and surgical quality as measured by complications, node yield and surgical margins in this retrospective single-institution series.

Clinical outcomes of cT1 micropapillary bladder cancer.

PURPOSE: While many urologists recommend radical cystectomy for micropapillary bladder cancer invading the lamina propria (cT1), contradictory small reports exist on the efficacy of conservative management with intravesical bacillus Calmette-Guérin for this disease. We report our updated experience in what to our knowledge is the largest series of patients with cT1 micropapillary bladder cancer. MATERIALS AND METHODS: An institutional review board approved review of our cancer database identified 283 patients with micropapillary bladder cancer, including 72 staged with cT1N0M0 disease at diagnosis and initiation of therapy. Survival analysis was performed using the Kaplan-Meier estimator and compared using the log rank test. RESULTS: In this cohort of 72 patients 40 received primary intravesical bacillus Calmette-Guérin and 26 underwent up-front radical cystectomy. Of patients who received bacillus Calmette-Guérin 75%, 45% and 35% experienced disease recurrence, progression and lymph node metastasis, respectively. Patients treated with up-front cystectomy had improved survival compared to patients treated with primary bacillus Calmette-Guérin (5-year disease specific survival 100% vs 60% p = 0.006) and patients who underwent delayed cystectomy after recurrence (5-year disease specific survival 62%, p = 0.015). Prognosis was especially poor in patients who waited for progression before undergoing radical cystectomy with an estimated 5-year disease specific survival of only 24% and a median survival of 35 months. In patients treated with up-front cystectomy pathological up-staging was found in 27%, including 20% with lymph node metastasis. CONCLUSIONS: While certain patients with T1 micropapillary bladder cancer may respond to intravesical bacillus Calmette-Guérin, survival is improved in those who undergo early radical cystectomy. Further molecular studies are needed to identify subsets of patients in whom the bladder can be safely spared.

Posttraumatic stress and depressive symptoms in renal cell carcinoma: association with quality of life and utility of single-item distress screening.

OBJECTIVE: The purpose of this study was to examine the prevalence of posttraumatic stress symptoms (PTSS) in patients with renal cell carcinoma (RCC), the associations and co-occurrence between PTSS, depressive, and other cancer-related symptoms and the ability of a single-item distress question to identify patients with PTSS. METHODS: Patients with stage I-IV RCC completed assessments of depressive symptoms (Center for Epidemiologic Studies Depression Scale), PTSS (Impact of Event Scale), cancer-related symptoms (MD Anderson Symptom Inventory), fatigue (Brief Fatigue Inventory), and sleep disturbance (Pittsburgh Sleep Quality Index). We used the distress item on the MD Anderson Symptom Inventory as a distress screener and general linear model analyses to test study hypotheses. RESULTS: Of the 287 patients (29% stage IV; 42% female; mean age = 58 years), 46% (n = 131) reported psychiatric symptoms with 15% (n = 44) reporting comorbid clinical levels of depressive symptoms and PTSS, 24% (n = 70) PTSS alone, and 6% (n = 17) depressive symptoms alone. Controlling for age, gender, and stage, patients with comorbid depressive symptoms and PTSS reported more cancer-related symptoms (p < 0.0001), fatigue (p < 0.0001), and sleep disturbance (p = 0.0003) than those with PTSS alone and more cancer-related symptoms (p = 0.002) and fatigue (p = 0.09) than those with depressive symptoms alone. Sensitivity analyses revealed that 26.9% of negative cases on the distress item fell within the clinical range of the Impact of Event Scale and 9.3% of negative cases met caseness on the Center for Epidemiologic Studies Depression Scale. CONCLUSIONS: Posttraumatic stress symptoms occurred both independently and comorbid with depressive symptoms in patients with RCC. PTSS were correlated with overall cancer symptom burden. Single-item distress screening was less sensitive in detecting PTSS than depressive symptoms. Therefore, additional screening strategies are required in the clinical setting.

Psychological states, serum markers and survival: associations and predictors of survival in patients with renal cell carcinoma.

This study sought to determine if there was an association between prognostic-based serum biomarkers, survival, and psychosocial factors in patients with metastatic renal cell carcinoma. Associations were found between psychosocial factors and biomarker levels (hemoglobin with depressive symptoms (r = -0.29), positive affect (r = 0.30), social support (r = 0.19), and perceived stress (r = -0.27); albumin with depressive symptoms (r = -0.19), positive affect (r = 0.22), and social support (r = 0.20); alkaline phosphatase with depressive symptoms (r = 0.21), all p values <0.05. After adjustment for disease-related risk factors, only the associations between positive affect and perceived stress with hemoglobin remained significant (p's < 0.05). Positive affect (HR = 0.90; 95% CI = 0.83, 0.97; p = 0.009) and depressive symptom total scores (HR = 1.03; 95% CI = 1.01, 1.06; p = 0.013), and alkaline phosphatase (HR 2.72; 95% CI = 1.41, 5.24; p = 0.003) were associated with survival. This study suggests that measures of positive and negative psychological outlook may contribute differently to health, well-being, and survival.

The feasibility and safety of repeat cryosurgical ablation of localized prostate cancer.

BACKGROUND: The aim of the study was to assess the morbidity and efficacy of repeat cryoablation (CA) in the treatment of localized prostate cancer. METHODS: Twenty-seven patients with median age of 71 years (range 48-80) who underwent repeat CA between April 2003 and April 2011 at a single institution were included. The median initial prostate-specific antigens (PSA) and Gleason values were 6.2 ng/ml (range 4-23.6) and 7 (range 6-9), respectively. Twenty-four patients underwent two CA treatments, and three patients underwent three CA treatments. Pre- and perioperative parameters and oncological and functional outcomes were evaluated. RESULTS: No intraoperative complications occurred. After the first CA, PSA was undetectable in 10 patients, and the median nadir PSA value was 0.65 ng/ml (range 0.1-4.9). After the second CA, 4 patients had undetectable PSA, and the median nadir PSA value was 1.25 ng/ml (range 0.2-7.9). For patients who underwent a third CA treatment, no patients had undetectable PSA, and the subsequent median nadir PSA value was 1.6 ng/ml (range 0.4-4.5). Two patients had incontinence (1 pad per day) following repeat CA. One patient had urinary retention after the third CA treatment, and one had urethral stricture. The mean hospitalization and follow-up periods were 1 day (range 0-2) and 51.5 months (range 11-96), respectively. CONCLUSIONS: Repeat CA successfully reduced PSA levels, and complications were modest. We conclude that repeat CA is a feasible, safe, and effective treatment option for localized prostate cancer.
