Identification and Management of Testicular Mesothelioma Identified Intraoperatively: A Case Series.

Testicular mesothelioma lacks the characteristic presentation of testicular malignancy and often has normal biomarkers at the time of diagnosis causing this malignancy to be overlooked and diagnosed intraoperatively during elective scrotal surgery. We present two cases of testicular mesothelioma that were diagnosed incidentally during hydrocelectomy. These cases emphasize the importance of considering testicular mesothelioma during hydrocele and scrotal mass workup and demonstrate the need for standardized guidelines for the management of testicular mesothelioma.

Scrotal Dermatofibrosarcoma Protuberans in a Patient with Schizophrenia: A Case Report and Review of the Literature.

Dermatofibrosarcoma protuberans (DFSP) is a rare spindle cell soft tissue sarcoma of the dermis and subcutaneous tissue. We present the fourth case of scrotal DFSP in the literature, identified in a 32-year-old male with schizophrenia. Wide surgical excision and radical orchiectomy were performed revealing an uninvolved testicle and DFSP of the scrotum. A unique challenge to this case was concurrent aortic dissection and schizophrenia. Social determinants of health are associated with delay in presentation and poor appointment compliance in patients with schizophrenia. Ultimately, DFSP of the scrotum is an extremely rare condition with this presentation being only the fourth report in the literature. It is important to document these unique cases to establish differential diagnoses and optimize management.

Association between Presurgical Weight Status and Urinary and Sexual Function in Prostate Cancer Patients Treated by Radical Prostatectomy: A Prospective Cohort Study.

OBJECTIVE: To prospectively examine the influence of weight status on urinary and sexual function in clinically localized prostate cancer patients treated by radical prostatectomy (RP). METHODS: The Prostatectomy, Incontinence and Erectile dysfunction study recruited patients at 2 US institutions between 2011 and 2014. At baseline, height and weight were measured, and urinary and sexual function were collected by the modified Expanded Prostate Cancer Index Composite-50. This index was repeated at the 5-week, 6-month, and 12-month postsurgical assessments and compared to baseline using linear generalized estimating equations. Logistic equations were used to evaluate the likelihood of functional recovery at the 6- and 12-month assessments. RESULT: Presurgery, nonobese patients (68.8% of 407 patients) had similar urinary function as those with obesity (P = .217), but better sexual function (P = .006). One year after surgery, 50.5% and 28.9% patients had recovered to baseline levels for urinary and sexual function, respectively. Recovery was not, however, uniform by obesity. Compared to those with obesity, nonobese patients had better urinary function at the 6- (P < .001) and 12-month postsurgical assessments (P = .011) and were more likely to recover their function by the 6-month assessment (OR = 2.55, 95% CI = 1.36-4.76). For sexual function, nonobese patients had better function at the 6- (P = .028) and 12-month (P = .051) assessments, but a similar likelihood of recovery 1-year postsurgery. CONCLUSION: Nonobese prostate cancer patients had better and likely earlier recovery in urinary function postsurgery, and better sexual function both pre- and postsurgery. These findings support the potential for tailored presurgical counseling about RP side-effects and prehabilitation to improve these side-effects.

Primitive Neuroectodermal Tumor Presenting With a Large Subcapsular Hematoma in Pregnancy: A Case Report and Current Literature Review.

Primitive neuroectodermal tumors (PNET) are rare, small round cell tumors that are difficult to diagnose. It is important to identify PNET early, utilizing immunohistochemistry and genetic markers, as it is often an aggressive cancer. PNET is most commonly described in men between the ages of 20 and 40, with very few case reports highlighting the development in pregnant patients. We present a case of localized renal PNET in a pregnant patient and highlight the diagnostic work-up and treatment as well as the relationship between pregnancy and the potential development of aggressive tumors.

Decision aids for localized prostate cancer in diverse minority men: Primary outcome results from a multicenter cancer care delivery trial (Alliance A191402CD).

BACKGROUND: Decision aids (DAs) can improve knowledge for prostate cancer treatment. However, the relative effects of DAs delivered within the clinical encounter and in more diverse patient populations are unknown. A multicenter cluster randomized controlled trial with a 2×2 factorial design was performed to test the effectiveness of within-visit and previsit DAs for localized prostate cancer, and minority men were oversampled. METHODS: The interventions were delivered in urology practices affiliated with the NCI Community Oncology Research Program Alliance Research Base. The primary outcome was prostate cancer knowledge (percent correct on a 12-item measure) assessed immediately after a urology consultation. RESULTS: Four sites administered the previsit DA (39 patients), 4 sites administered the within-visit DA (44 patients), 3 sites administered both previsit and within-visit DAs (25 patients), and 4 sites provided usual care (50 patients). The median percent correct in prostate cancer knowledge, based on the postvisit knowledge assessment after the intervention delivery, was as follows: 75% for the pre+within-visit DA study arm, 67% for the previsit DA only arm, 58% for the within-visit DA only arm, and 58% for the usual-care arm. Neither the previsit DA nor the within-visit DA had a significant impact on patient knowledge of prostate cancer treatments at the prespecified 2.5% significance level (P = .132 and P = .977, respectively). CONCLUSIONS: DAs for localized prostate cancer treatment provided at 2 different points in the care continuum in a trial that oversampled minority men did not confer measurable gains in prostate cancer knowledge.

Improved survival with post-diagnostic metformin and statin use in a racially diverse cohort of US Veterans with advanced prostate cancer.

OBJECTIVE: To examine the association between post-diagnostic metformin or statin use with all-cause and prostate cancer (PCa)-specific mortality in men with advanced prostate cancer. METHODS: Our study consisted of 4572 men (Black = 1352, White = 3192, Other Race = 28) diagnosed with advanced cancer (T4/M1/N1) between 1999 and 2013 in the Veteran Health Administration. The association between post-diagnostic (1) metformin and (2) statin use with all-cause and PCa-specific mortality was examined using multivariable, time-varying Cox Proportional Hazard Models. In a secondary analysis, models were stratified by race. RESULTS: Post-diagnostic metformin use was associated with a reduced risk of all-cause (Hazard Ratio (HR) 0.84, 95% Confidence Interval (CI): 0.73, 0.96) and PCa-specific death (HR: 0.76, 95% CI: 0.63, 0.91). In stratified analyses, the inverse association between post-diagnostic metformin use and both all-cause PCa-specific mortality was limited to White men. Post-diagnostic statin use was associated with a reduced risk of all-cause (HR: 0.75, 95% CI: 0.68, 0.83) and PCa-specific mortality (HR: 0.72; 95% CI: 0.64, 0.81). In stratified analyses, similar inverse associations were observed for post-diagnostic statin use and all-cause and PCa-specific mortality in both Black and White men. CONCLUSION: Post diagnostic metformin and statin use may prevent progression to lethal prostate cancer in men with advanced prostate cancer.

Umbilical sparing robotic partial cystectomy for localized urachal adenocarcinoma: A case report.

Urachal adenocarcinoma, the third most common histopathological type of non-urothelial bladder cancer, is often aggressive, presenting in advanced stages. Increased understanding of the embryologic origin of the tumor with concurrent advances in surgical technique have allowed partial cystectomy to become the gold standard of surgical treatment. However, the benefit of en bloc umbilectomy remains questionable. Here we present the diagnosis and management of 67- year old patient diagnosed with mucinous cystadenocarcinoma of the urachus treated with umbilical-sparing robotic partial cystectomy. We also provide a review of the existing literature on this rare tumor and its management.

Autocrine signaling by receptor tyrosine kinases in urothelial carcinoma of the bladder.

Comprehensive characterizations of bladder cancer (BCa) have established molecular phenotype classes with distinct alterations and survival trends. Extending these studies within the tyrosine kinase (TK) family to identify disease drivers could improve our use of TK inhibitors to treat specific patient groups or individuals. We examined the expression distribution of TKs as a class (n = 89) in The Cancer Genome Atlas (TCGA) muscle invasive BCa data set (n >400). Patient profiles of potentially oncogenic alterations (overexpression and/or amplification) clustered TKs into 3 groups; alterations of group 1 and 3 TKs were associated with significantly worse patient survival relative to those without alterations. Many TK pathways induce epithelial-to-mesenchymal transition (EMT), which promotes tumor invasiveness and metastasis. Overexpression and/or amplification among 9 EMT transcriptional activators occurred in 43% of TCGA cases. Co-occurring alterations of TKs and EMT transcriptional activators involved most group 1 TKs; 24% of these events were associated with significantly worse patient survival. Co-occurring alterations of receptor TKs and their cognate ligands occurred in 16% of TCGA cases and several BCa-derived cell lines. Suppression of GAS6, MST1 or CSF1, or their respective receptors (AXL, MST1R and CSF1R), in BCa cell lines was associated with decreased receptor activation, cell migration, cell proliferation and anchorage independent cell growth. These studies reveal the patterns and prevalence of potentially oncogenic TK pathway-related alterations in BCa and identify specific alterations associated with reduced BCa patient survival. Detection of these features in BCa patients could better inform TK inhibitor use and improve clinical outcomes.

One-year urinary and sexual outcome trajectories among prostate cancer patients treated by radical prostatectomy: a prospective study.

BACKGROUND: To examine one-year trajectories of urinary and sexual outcomes, and correlates of these trajectories, among prostate cancer patients treated by radical prostatectomy (RP). METHODS: Study participants were recruited from 2011 to 2014 at two US institutions. Self-reported urinary and sexual outcomes were measured at baseline before surgery, and 5 weeks, 6 months and 12 months after surgery, using the modified Expanded Prostate Cancer Index Composite-50 (EPIC-50). Changes in EPIC-50 scores from baseline were categorized as improved (beyond baseline), maintained, or impaired (below baseline), using previously-reported minimum clinically important differences. RESULTS: Of the 426 eligible participants who completed the baseline survey, 395 provided data on at least one EPIC-50 sub-scale at 5 weeks and 12 months, and were analyzed. Although all mean EPIC-50 scores declined markedly 5 weeks after surgery and then recovered to near (incontinence-related outcomes) or below (sexual outcomes) baseline levels by 12 months post-surgery, some men experienced improvement beyond their baseline levels on each sub-scale (3.3-51% depending on the sub-scale). Having benign prostatic hyperplasia (BPH) at baseline (prostate size ≥ 40 g; an International Prostate Symptom Index Score ≥ 8; or using BPH medications) was associated with post-surgical improvements in voiding dysfunction-related bother at 5 weeks (OR = 3.9, 95% CI: 2.1-7.2) and 12 months (OR = 3.3, 95% CI: 2.0-5.7); and in sexual bother at 5 weeks (OR = 5.7, 95% CI:1.7-19.3) and 12 months (OR = 3.0, 95% CI: 1.2-7.1). CONCLUSIONS: Our findings provide additional support for considering baseline BPH symptoms when selecting the best therapy for early-stage prostate cancer.

Intraoperative MRI for newly diagnosed supratentorial glioblastoma: a multicenter-registry comparative study to conventional surgery.

OBJECTIVE: Intraoperative MRI (iMRI) is used in the surgical treatment of glioblastoma, with uncertain effects on outcomes. The authors evaluated the impact of iMRI on extent of resection (EOR) and overall survival (OS) while controlling for other known and suspected predictors. METHODS: A multicenter retrospective cohort of 640 adult patients with newly diagnosed supratentorial glioblastoma who underwent resection was evaluated. iMRI was performed in 332/640 cases (51.9%). Reviews of MRI features and tumor volumetric analysis were performed on a subsample of cases (n = 286; 110 non-iMRI, 176 iMRI) from a single institution. RESULTS: The median age was 60.0 years (mean 58.5 years, range 20.5-86.3 years). The median OS was 17.0 months (95% CI 15.6-18.4 months). Gross-total resection (GTR) was achieved in 403/640 cases (63.0%). Kaplan-Meier analysis of 286 cases with volumetric analysis for EOR (grouped into 100%, 95%-99%, 80%-94%, and 50%-79%) showed longer OS for 100% EOR compared to all other groups (p < 0.01). Additional resection after iMRI was performed in 104/122 cases (85.2%) with initial subtotal resection (STR), leading to a 6.3% mean increase in EOR and a 2.2-cm3 mean decrease in tumor volume. For iMRI cases with volumetric analysis, the GTR rate increased from 54/176 (30.7%) on iMRI to 126/176 (71.5%) postoperatively. The EOR was significantly higher in the iMRI group for intended GTR and STR groups (p = 0.02 and p < 0.01, respectively). Predictors of GTR on multivariate logistic regression included iMRI use and intended GTR. Predictors of shorter OS on multivariate Cox regression included older age, STR, isocitrate dehydrogenase 1 (IDH1) wild type, no O6-methylguanine DNA methyltransferase (MGMT) methylation, and no Stupp therapy. iMRI was a significant predictor of OS on univariate (HR 0.82, 95% CI 0.69-0.98; p = 0.03) but not multivariate analyses. Use of iMRI was not associated with an increased rate of new permanent neurological deficits. CONCLUSIONS: GTR increased OS for patients with newly diagnosed glioblastoma after adjusting for other prognostic factors. iMRI increased EOR and GTR rate and was a significant predictor of GTR on multivariate analysis; however, iMRI was not an independent predictor of OS. Additional supporting evidence is needed to determine the clinical benefit of iMRI in the management of glioblastoma.

Risk of Prostate Cancer-related Death Following a Low PSA Level in the PLCO Trial.

Longer-than-annual screening intervals have been suggested to improve the balance of benefits and harms in prostate cancer screening. Many researchers, societies, and guideline committees have suggested that screening intervals could depend on the prostate-specific antigen (PSA) result. We analyzed data from men (N = 33,897) ages 55-74 years with a baseline PSA test in the intervention arm of the Prostate, Lung, Colorectal and Ovarian Cancer Screening trial (United States, 1993-2001). We estimated 5- and 10-year risks of aggressive cancer (Gleason ≥8 and/or stage III/IV) and 15-year risks of prostate cancer-related mortality for men with baseline PSA ≤ 0.5 ng/mL (N = 4,862), ≤1 ng/mL (N = 15,110), and 1.01-2.5 ng/mL (N = 12,422). A total of 217 men died from prostate cancer through 15 years, although no men with PSA ≤ 1 ng/mL died from prostate cancer within 5 years [95% confidence interval (CI), 0.00%-0.03%]. The 5-year incidence of aggressive disease was low (0.08%; 95% CI, 0.03%-0.12%) for men with PSA ≤ 1 ng/mL, and higher for men with baseline PSA 1.01-2.5 ng/mL (0.51%; 95% CI, 0.38%-0.74%). No men aged ≥65 years with PSA ≤ 0.5 ng/mL died from prostate cancer within 15 years (95% CI, 0.00%-0.32%), and their 10-year incidence of aggressive disease was low (0.25%; 95% CI, 0.00%-0.53%). Compared with white men, black men with PSA ≤ 1 ng/mL had higher 10-year rates of aggressive disease (1.6% vs. 0.4%; P < 0.01). Five-year screening intervals may be appropriate for the 45% of men with PSA ≤ 1 ng/mL. Men ages ≥65 years with PSA ≤ 0.5 ng/mL could consider stopping screening. Substantial risk disparities suggest appropriate screening intervals could depend on race/ethnicity.

Recurrent Hemispheric Stroke Syndromes in Symptomatic Atherosclerotic Internal Carotid Artery Occlusions: The Carotid Occlusion Surgery Study Randomized Trial.

BACKGROUND: There are limited data on outcomes of extracranial-intracranial (EC-IC) bypass in patients with recurrent hemispheric syndromes due to atherosclerotic internal carotid artery occlusion (AICAO). OBJECTIVE: To compare clinical outcomes and efficacy of EC-IC bypass surgery in patients with and without recurrent hemispheric syndromes associated with AICAO in the Carotid Occlusion Surgery Study (COSS). METHODS: In patients enrolled in the COSS trial, we compared baseline characteristics and clinical outcomes for participants with (rHEMI+) and without recurrent hemispheric ischemia (rHEMI-) prior to randomization into surgical vs medical groups. The primary outcome was all stroke and death from randomization through 30 d and ipsilateral ischemic stroke within 2 yr. RESULTS: Of 195 randomized participants, 100 were rHEMI+ (50 in each group). Baseline characteristics between rHEMI+ and rHEMI- participants were similar except rHEMI+ were more likely to have had previous stroke prior to randomization (61% vs 20%, P < .01) and to have TIA as the entry event (59% vs 21%, P < .01). All primary endpoints were ipsilateral ischemic strokes. There were no significant differences in occurrence of the primary endpoint between nonsurgical and surgical participants in rHEMI+ (26.3% vs 22.4%, P = .660) and rHEMI- (18.9% vs 19.5%, P = .943). For nonsurgical participants, there was no significant difference in the primary endpoint for rHEMI+ vs rHEMI- patients (P = .410). CONCLUSION: Patients with recurrent hemispheric stroke syndromes enrolled in the COSS trial did not show benefit from EC-IC bypass compared to medical treatment. Early aggressive risk factor measures should be prioritized to reduce recurrent strokes in these patients.

Effectiveness of postoperative radiotherapy after radical cystectomy for locally advanced bladder cancer.

BACKGROUND: Local-regional failure (LF) for locally advanced bladder cancer (LABC) after radical cystectomy (RC) is common even with chemotherapy and is associated with high morbidity/mortality. Postoperative radiotherapy (PORT) can reduce LF and may enhance overall survival (OS) but has no defined role. We hypothesized that the addition of PORT would improve OS in LABC in a large nationwide oncology database. METHODS: We identified ≥ pT3pN0-3M0 LABC patients in the National Cancer Database diagnosed 2004-2014 who underwent RC ± PORT. OS was calculated using Kaplan-Meier and Cox proportional hazards regression modeling was used to identify predictors of OS. Propensity matching was performed to match RC patients who received PORT vs those who did not. RESULTS: 15,124 RC patients were identified with 512 (3.3%) receiving PORT. Median OS was 20.0 months (95% CI, 18.2-21.8) for PORT vs 20.8 months (95% CI, 20.3-21.3) for no PORT (P = 0.178). In multivariable analysis, PORT was independently associated with improved OS: hazard ratio 0.87 (95% CI, 0.78-0.97); P = 0.008. A one-to-three propensity match yielded 1,858 patients (24.9% receiving PORT and 75.1% without). In the propensity-matched cohort, median OS was 19.8 months (95% CI, 18.0-21.6) for PORT vs 16.9 months (95% CI, 15.6-18.1) for no PORT (P = 0.030). In the propensity-matched cohort of urothelial carcinoma patients (N = 1,460), PORT was associated with improved OS for pT4, pN+, and positive margins (P < 0.01 all). CONCLUSION: In this observational cohort, PORT was associated with improved OS in LABC. While the data should be interpreted cautiously, these results lend support to the use of PORT in selected patients with LABC, regardless of histology. Prospective trials of PORT are warranted.

Self-Management in Long-Term Prostate Cancer Survivors: A Randomized, Controlled Trial.

PURPOSE: This randomized clinical trial compared a personally tailored, automated telephone symptom management intervention to improve self-management among long-term survivors of prostate cancer with usual care enhanced with a nontailored newsletter about symptom management. We hypothesized that intervention-group participants would have more confident symptom self-management and reduced symptom burden. METHODS: A total of 556 prostate cancer survivors who, more than 1 year after treatment, were experiencing symptom burden were recruited from April 2015 to February 2017 across four Veterans Affairs sites. Participants were randomly assigned to intervention (n = 278) or usual care (n = 278) groups. We compared differences in the primary (symptom burden according to Expanded Prostate Cancer Index Composite-26 [EPIC], confidence in self-management) and secondary outcomes between groups using intent-to-treat analyses. We compared domain-specific changes in symptom burden from baseline to 5 and 12 months among the intervention group according to the primary symptom focus area (urinary, bowel, sexual, general) of participants. RESULTS: Most of the prostate cancer survivors in this study were married (54.3%), were white (69.2%), were retired (62.4%), and underwent radiation therapy (56.7% v 46.2% who underwent surgery), and the mean age was 67 years. There were no baseline differences in urinary, bowel, sexual, or hormonal domain EPIC scores across groups. We observed higher EPIC scores in the intervention arm in all domain areas at 5 months, though differences were not statistically significant. No differences were found in secondary outcomes; however, coping appraisal was higher (2.8 v 2.6; P = .02) in intervention-arm patients at 5 months. In subgroup analyses, intervention participants reported improvement from baseline at 5 and 12 months in their symptom focus area domains. CONCLUSION: This intervention was well received among veterans who were long-term survivors of prostate cancer. Although overall outcome differences were not observed across groups, the intervention tailored to symptom area of choice may hold promise to improve associated burden.

Levels and patterns of self-reported and objectively-measured free-living physical activity among prostate cancer survivors: A prospective cohort study.

BACKGROUND: No prior study has measured or compared self-reported and objectively measured physical activity trajectories in prostate cancer survivors before and after treatment. METHODS: Clinically localized prostate cancer patients treated with radical prostatectomy were recruited between 2011 and 2014. Of the 350 participants enrolled at the main site, 310 provided self-reported physical activity at baseline before radical prostatectomy, and 5 weeks, 6 months, and 12 months after radical prostatectomy. A subset of participants (n = 81) provided objectively measured physical activity at all study time points by wearing an accelerometer for 7 days each. Changes in activity over time were compared using Friedman's test. Agreement between self-reported and objective measures was evaluated using Spearman's rank correlation coefficient. RESULTS: Self-reported moderate-to-vigorous physical activity was high at baseline (median, 32.1 min/day), followed by a decline at 5 weeks (median, 15.0 min/day) and a recovery at 6 and 12 months (median, 32.1-47.1 min/day). In contrast, objectively measured moderate-to-vigorous physical activity was low at all 4 time points (median, 0.0-5.2 min/day), with no overall change across study assessments (global P = .29). Self-reported moderate-to-vigorous physical activity tended to be more closely related to objectively measured light-intensity physical activity (ρ = 0.29-0.42) than to objectively measured moderate-to-vigorous physical activity (ρ = 0.07-0.27, P = .009-.32). CONCLUSIONS: In our population of prostate cancer survivors with critically low moderate-to-vigorous physical activity levels, self-reported measures greatly overestimated moderate-to-vigorous physical activity and may have been more reflective of light-intensity physical activity. Because cancer survivor guidelines are derived from self-reported data, our findings may imply that intensities of physical activity below moderate, such as light intensity, still have health benefits.

Prostate Cancer: Update on Early Detection and New Biomarkers.

Screening and early treatment of prostate cancer (PCa) has recently come under scrutiny due to the rates of overdiagnosis of low risk cancer. Randomized trials, including ERSPC and PLCO, have informed our understanding of the survival benefit provided by systematic PCa screening with serum prostate-specific antigen (PSA). To reduce the number of patients diagnosed with indolent disease, new adjuvant risk stratification tests have become available.

Heterogeneity in Definitions of High-risk Prostate Cancer and Varying Impact on Mortality Rates after Radical Prostatectomy.

BACKGROUND: Multiple definitions of high-risk prostate cancer (PC) exist in clinical practice. Prior studies have primarily evaluated the variability in prediction of biochemical recurrence. OBJECTIVE: To examine the impact of different definitions on mortality after radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS: Retrospective study of 6477 men with clinically localized disease undergoing RP at Barnes-Jewish Hospital (St. Louis, MO, USA) and Cleveland Clinic (Cleveland, OH, USA) between 1995 and 2007. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Seven pretreatment definitions of high-risk PC (prostate-specific antigen [PSA] ≥20ng/ml, biopsy Gleason score 8-10, clinical stage ≥T2c, cT3, D'Amico definition, National Comprehensive Cancer Network definition, Kattan nomogram) were evaluated. The Kaplan-Meier method was used to generate unadjusted survival estimates. Multivariable Cox proportional hazard regression models (controlling for age) were used to estimate the hazard ratio (HR) for PC-specific mortality (PCSM) and overall mortality (OM) in the high-risk group compared to men with lower risk not meeting that definition. RESULTS AND LIMITATIONS: 6477 men were treated with RP from 1995 to 2007 and were followed for a median of 67 mo. Depending on the definition, patients with high-risk PC comprised between 0.7% (when using cT3 as the criterion) and 8.2% (when using the D'Amico criterion) of the population. The 10-yr PC survival estimates varied from 89.7% (PSA ≥20ng/ml) to 69.7% (cT3) and overall survival ranged from 83.4% to 58.1%. On multivariable analysis, all high-risk definitions were associated with a higher risk of PCSM compared to lower risk (HR ranging from 4.38 for PSA ≥20ng/ml to 19.97 for cT3; all p<0.001). All definitions of high risk except for preoperative PSA ≥20ng/ml were associated with a higher risk of OM (HR 1.72 for D'Amico to 3.31 for cT3; all p<0.01). CONCLUSIONS: Heterogeneity in outcomes existed, depending on the pretreatment definition of high-risk PC. Clinical stage T3 and Gleason score 8-10 were most strongly associated with PCSM and OM. PATIENT SUMMARY: There is variability in prostate cancer outcomes after surgery, depending on the definition of pretreatment high-risk disease used. Clinical stage T3 and high Gleason score were most strongly associated with prostate cancer-specific mortality and overall mortality.

Prostate Magnetic Resonance Imaging Provides Limited Incremental Value Over the Memorial Sloan Kettering Cancer Center Preradical Prostatectomy Nomogram.

OBJECTIVE: To examine the incremental value of prostate magnetic resonance imaging (MRI) when used in combination with the currently available preoperative risk stratification tool, the Memorial Sloan Kettering Cancer Center (MSKCC) preradical prostatectomy nomogram. MATERIALS AND METHODS: We reviewed our institutional database of prostate MRI performed before radical prostatectomy between December 2014 and March 2016 (n = 236). We generated a logistic regression model based on observed final pathology results and the MSKCC nomogram predictions for organ-confined disease, extracapsular extension (ECE), seminal vesicle invasion, and lymph node involvement (LNI) ("MSKCC only"). We then generated a combined regression model incorporating both the MSKCC nomogram prediction with the degree of prostate MRI suspicion ("MSKCC + MRI"). Receiver operating characteristic curves were generated, and the area under the curves (AUCs) were compared. RESULTS: When independently examining the MSKCC nomogram predicted risk and the degree of prostate MRI suspicion, MRI was a predictor for ECE (odds ratio 2.8, P <.01) and LNI (odds ratio 5.6, P = .01). When examining the "MSKCC + MRI" and "MSKCC only" models, the incremental benefit in risk discrimination from the combined model ("MSKCC + MRI") was not significant for organ-confined disease, ECE, seminal vesicle invasion, or LNI (ΔAUC +0.03, P = .10; ΔAUC +0.03, P = .08; ΔAUC 0.63, P = .63; ΔAUC +0.04, P = .42; respectively). CONCLUSION: A combined model with prostate MRI and the MSKCC nomogram provides no additional risk discrimination over the MSKCC nomogram-based model alone. Evaluation of prostate MRI as a predictive tool should be performed in combination with, not independent of, these clinical risk stratification models.

Intravesical rAd-IFNα/Syn3 for Patients With High-Grade, Bacillus Calmette-Guerin-Refractory or Relapsed Non-Muscle-Invasive Bladder Cancer: A Phase II Randomized Study.

Purpose Many patients with high-risk non-muscle-invasive bladder cancer (NMIBC) are either refractory to bacillus Calmette-Guerin (BCG) treatment or may experience disease relapse. We assessed the efficacy and safety of recombinant adenovirus interferon alfa with Syn3 (rAd-IFNα/Syn3), a replication-deficient recombinant adenovirus gene transfer vector, for patients with high-grade (HG) BCG-refractory or relapsed NMIBC. Methods In this open-label, multicenter (n = 13), parallel-arm, phase II study ( ClinicalTrials.gov identifier: NCT01687244), 43 patients with HG BCG-refractory or relapsed NMIBC received intravesical rAd-IFNα/Syn3 (randomly assigned 1:1 to 1 × 1011 viral particles (vp)/mL or 3 × 1011 vp/mL). Patients who responded at months 3, 6, and 9 were retreated at months 4, 7, and 10. The primary end point was 12-month HG recurrence-free survival (RFS). All patients who received at least one dose were included in efficacy and safety analyses. Results Forty patients received rAd-IFNα/Syn3 (1 × 1011 vp/mL, n = 21; 3 × 1011 vp/mL, n = 19) between November 5, 2012, and April 8, 2015. Fourteen patients (35.0%; 90% CI, 22.6% to 49.2%) remained free of HG recurrence 12 months after initial treatment. Comparable 12-month HG RFS was noted for both doses. Of these 14 patients, two experienced recurrence at 21 and 28 months, respectively, after treatment initiation, and one died as a result of an upper tract tumor at 17 months without a recurrence. rAd-IFNα/Syn3 was well tolerated; no grade four or five adverse events (AEs) occurred, and no patient discontinued treatment because of an adverse event. The most frequently reported drug-related AEs were micturition urgency (n = 16; 40%), dysuria (n = 16; 40%), fatigue (n = 13; 32.5%), pollakiuria (n = 11; 28%), and hematuria and nocturia (n = 10 each; 25%). Conclusion rAd-IFNα/Syn3 was well tolerated. It demonstrated promising efficacy for patients with HG NMIBC after BCG therapy who were unable or unwilling to undergo radical cystectomy.

Caution with Use of the EPIC-50 Urinary Bother Scale: How Voiding Dysfunction Modifies its Performance.

PURPOSE: We evaluated agreement between patient reported urinary function and bother, and sexual function and bother in patients treated with radical prostatectomy to help inform possible nonfunctional, modifiable mechanisms for patient bother. MATERIALS AND METHODS: Patients were recruited from 2011 to 2014 at Washington University, and Brigham and Women's Hospital. Urinary and sexual outcomes were assessed by EPIC-50 (Expanded Prostate Cancer Index Composite-50) before, 5 weeks and 12 months after radical prostatectomy. Spearman rank correlation coefficients and agreement/disagreement categories were used to describe the relation between function and bother. RESULTS: Despite moderate to good agreement between function and bother (urinary r = 0.51-0.69 and sexual r = 0.65-0.80) discordant groups were observed. In the urinary domain these groups were men disproportionately bothered by function at baseline (16.9%) and 12 months after radical prostatectomy (6.1%) and men less bothered by function 5 weeks (26.8%) and 12 months (9.9%) after radical prostatectomy. Discordant groups in the sexual domain were men less bothered by function at baseline (20.8%), and 5 weeks (21.1%) and 12 months (15.7%) after radical prostatectomy. Splitting the urinary bother scale into 2 subscales, including one for incontinence related bother to complement the urinary function scale which measures only incontinence, and one for voiding dysfunction related bother yielded considerably better agreement (urinary function and incontinence related bother r = 0.78-0.83). Factors contributing to the group less bothered by sexual function were unclear. CONCLUSIONS: When using EPIC-50, investigators should consider splitting the urinary bother scale by the relation to incontinence to prevent distortions of function-bother and comparisons before vs after radical prostatectomy by coexisting voiding dysfunction.
