Introduction: According to TNM staging, pathological T4ab are comprehensive of the invasion of prostate, seminal vesicles, uterus or vagina and pelvic or abdominal wall. However, few data are available on the perioperative and oncological outcomes of specific organ invasion. Materials and Methods: A total of 917 consecutive bladder cancer (BCa) patients treated with radical cystectomy (RC) at a single institution between 1990 and 2015 were studies. Cox regression analyses were used to stratify pT4ab according to the site of invasion and survival. Results: Overall, 176 (19.2%) and 40 (4.4%) patients harbored pT4a or pT4b disease. Specifically, 84 (9.2%) patients reported prostate and/or SVI invasion, 62 (6.8%) prostate only, 16 (1.7%) uterus, 14 (1.5%) vaginal, 24 (2.6%) pelvic wall, and 16 (1.7%) abdominal wall invasion. The median follow-up in pT4 patients was 48 months. The 1-year cancer-specific mortality (CSM) rates were 71, 65, 24, 50, 50, and 72%, for vaginal, uterus, prostate only, prostate and/or seminal vesicles, pelvic wall, and abdominal wall invasions, respectively. At multivariable Cox regression, the invasion of prostate only (hazard ratio [HR] 3.53), prostate and/or SVI (HR 4.98), uterus (HR 7.16), vagina (HR 6.12), pelvic (HR 11.81), abdominal (8.36) were associated with adverse CSM. Conclusions: Our study described the differences in survival related to invasion site in pT4 patients, confirming poor survival expectancies in this subgroup. Patients with prostate invasion only seem to be associated with better survival than those affected by concomitant invasion of seminal vesicles. Uterus and vaginal invasions were associated with poor survival outcomes. Patients Summary: In this study, we looked at the outcome of locally advanced invasive BCa (stage pT4) in patients treated with RC at a tertiary referral hospital. We analyzed the differences in survival related to the specific organ invasion. We confirmed poor survival in this subgroup of patients. Only patients who had prostate invasion only seem to have a better survival. [ABSTRACT FROM AUTHOR]

Background: The Deyo/Charlson co-morbidity index (CCI) and Klabunde co-morbidity index (KCI) co-morbidity indexes represent outdated indexes when the endpoint of complications after radical prostatectomy (RP) is considered. A novel group of co-morbidities derived from International Classification of Diseases-9 diagnostic codes in a contemporary RP database could provide better accuracy. Research Design, Subjects and Measures: We relied on 20,484 patients with clinically localized non-metastatic prostate cancer treated with RP between 2000 and 2009 in the Surveillance, Epidemiology, and End Results-Medicare linked database. We examined 2 endpoints, namely, 90-day medical complication rate and 90-day surgical complication rate after RP. Simulated annealing (SA) was used to develop a novel co-morbidity index. Finally, the newly identified groups of co-morbid conditions were compared with the CCI and Klabunde indexes. Results: Our SA identified 10 and 7 individual co-morbid conditions able to predict 90-day medical and surgical complications respectively. This novel model showed improved predictive accuracy over CCI and KCI for the 2 endpoints considered (respectively: 59.4 vs. 58.1 and 58.0% for medical complications, 58.0 vs. 56.8 and 56.7% for surgical complications). Conclusions: The newly defined groupings of co-morbid conditions resulted in better ability to predict the 2 endpoints of interest compared to CCI and KCI. However, the gain was marginal. This implies that better tools should be defined to more accurately predict these outcomes. [ABSTRACT FROM AUTHOR]

Objective: The study aimed to evaluate the impact of the different types of prostate involvement at the time of radical cystoprostatectomy (RCP). Methods: Data from 893 male patients treated with RCP at a referral center for bladder cancer (BCa) were assessed. Prostatic urothelial carcinoma (PUC) was stratified as stromal vs. urethral/duct involvements. Multivariable Cox regression analyses were built to test the impact of the presence of incidental prostate cancer (PCa) and PUC on survival outcomes. Results: PCa was present in 319 (35.7%) RCP patients, of which 45 (14.1%) had significant PCa disease. PUC was identified in 181 patients (20%): 75 (41.1%) with urethral/duct involvement and 106 (58.6%) with stromal. Within a median follow-up of 72 months, stromal PUC, but not the other forms of PUC or PCa, was associated with worse survival outcomes. In multivariable analyses adjusted for the effects of standard features, stromal PUC remained associated with recurrence (hazards ratio [HR] 2.01, p = 0.03), cancer-specific mortality (HR 1.65, p = 0.01), and overall mortality (HR 1.45, p = 0.03). Conclusion: Prostatic stromal invasion with urothelial carcinoma confers a poor survival expectation to BCa patients after surgical treatment. Conversely, other type of urothelial prostatic invasions or the presence of concomitant PCa does not seem to be associated with differences in survival outcomes. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to analyze the reasons for intravesical BCG interruption in clinical practice. BCG for at least one year is advocated as the best regimen to treat high-risk non-muscle invasive bladder cancer (NMIBC). However, almost 50% of patients don't complete it. Toxicity accounts for 10% of dropouts in international trials. Materials and Methods: Patients with T1HG NMIBC undergoing 1-year BCG were enrolled in this study. BCG was administered for one year. Toxicity and causes of treatment interruption were recorded. Results: A total of 411 patients were enrolled in the study. Out of these total number of patients, 380 (92.5%) completed the induction cycle and 215 (52.3%) completed one year. Toxicity requiring interruption or postponement was recorded in 25 (6.1%) and 60 (14.6%) patients. Ninety-three patients (30.2%) stopped BCG, 9 (9.7%) for recurrence and 14 (15.1%) for grade-3 toxicity. Intriguingly, 55 (59.1%) patients refused BCG due to mild discomfort and deterioration in quality of social life. Conclusions: Grades 2-3 toxicity causes BCG interruption in a few cases. Almost 60% of interruptions are attributable to persistent grade-1 toxicity, which is inadequately treated. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
