RESUMO
BACKGROUND: Radical cystectomy with pelvic lymph node dissection is the recommended treatment in non-metastatic muscle-invasive bladder cancer (MIBC). In randomised trials, robot-assisted radical cystectomy (RARC) showed non-inferior short-term oncological outcomes compared with open radical cystectomy (ORC). Data on intermediate and long-term oncological outcomes of RARC are limited. OBJECTIVE: To assess the intermediate-term overall survival (OS) and recurrence-free survival (RFS) of patients with MIBC and high-risk non-MIBC (NMIBC) who underwent ORC versus RARC in clinical practice. METHODS AND MATERIALS: A nationwide retrospective study in 19 Dutch hospitals including patients with MIBC and high-risk NMIBC treated by ORC (nâ¯=â¯1086) or RARC (nâ¯=â¯386) between January 1, 2012 and December 31, 2015. Primary and secondary outcome measures were median OS and RFS, respectively. Survival outcomes were estimated using Kaplan-Meier curves. A multivariable Cox regression model was developed to adjust for possible confounders and to assess prognostic factors for survival including clinical variables, clinical and pathological disease stage, neoadjuvant therapy and surgical margin status. RESULTS: The median follow-up was 5.1 years (95% confidence interval ([95%CI] 5.0-5.2). The median OS after ORC was 5.0 years (95%CI 4.3-5.6) versus 5.8 years after RARC (95%CI 5.1-6.5). The median RFS was 3.8 years (95%CI 3.1-4.5) after ORC versus 5.0 years after RARC (95%CI 3.9-6.0). After multivariable adjustment, the hazard ratio for OS was 1.00 (95%CI 0.84-1.20) and for RFS 1.08 (95%CI 0.91-1.27) of ORC versus RARC. Patients who underwent ORC were older, had higher preoperative serum creatinine levels and more advanced clinical and pathological disease stage. CONCLUSION: ORC and RARC resulted in similar intermediate-term OS and RFS in a cohort of almost 1500 MIBC and high-risk NMIBC.

BACKGROUND: Although urinary adverse events after treatment of prostate cancer (CaP) are common, population-based studies on functional outcomes are scarce. The aim of this study is to evaluate the occurrence of urinary incontinence (UI) and erectile dysfunction (ED) in daily clinical practice using a nationwide Dutch cohort of patients with localized or locally advanced CaP. BASIC PROCEDURES: Patients were invited to complete the EPIC-26 questionnaire before treatment (baseline) and at 12 and 24 months after diagnosis. We calculated the mean EPIC-26 domain scores, stratified by treatment modality (i.e., radical prostatectomy, external radiotherapy, and no active treatment), and the proportions of patients with UI (defined as ≥ 2 pads per day) and ED (defined as erections not firm enough for sexual intercourse). Logistic regression modeling was used to explore the factors related to UI and ED after surgery. MAIN FINDINGS: In total 1,759 patients participated in this study. Patients undergoing radical prostatectomy experienced clinically relevant worsening in the urinary incontinence domain. After excluding patients who reported UI at baseline, 15% of patients with prostatectomy reported UI 24 months after diagnosis. Only comorbidity was associated with UI in surgically treated patients. Regardless of treatment, patients reported a clinically significant reduced sexual functioning over time. Before treatment, 54% of patients reported ED. Among the 46% remaining patients, 87% of patients treated with radical prostatectomy reported ED 24 months after diagnosis, 41% after radiotherapy, and 46% in patients without active treatment. Bilateral nerve-sparing surgery was the only factor associated with ED after 24 months. PRINCIPAL CONCLUSIONS: UI and ED frequently occur in patients with localized and locally advanced CaP, in particular after radical prostatectomy. The higher occurrence rate of UI and ED, compared with clinical trial participants, supports the importance of real-world data, which can be used for local treatment recommendations and patient information, but also to evaluate effects of future initiatives, such as treatment centralization and research aimed at improving functional outcomes.

OBJECTIVE: To determine the effect of radical prostatectomy (RP) hospital volume on the probability of post-RP incontinence. DESIGN: Retrospective research based on claims-based data of health insurers. METHOD: For every patient with RP the probability of incontinence was determined, based on the definition of claims of one or more incontinence pads per day. Casemix corrections were made based on indicators available in claims-data: age, lymph node dissection, and radiotherapy. No casemix corrections could be made for tumour stage and surgical technique. RESULTS: A total of 1590 patients were included in this study; for 26.0% of these patients, an average of one or more incontinence pads per day were claimed for. A significant relation between the volume of RP per hospital and the claims of incontinence material was observed. The probability of incontinence was significantly lower in hospitals with a volume of more than 100 RP patients per year when compared to hospitals with less than 100 RP patients per year. CONCLUSION: The probability of post-RP incontinence decreases as hospitals conduct more RP procedures. The casemix factors included in the analysis only had a limited impact on this observation.

BACKGROUND: Following radical nephro-ureterectomy for urothelial carcinoma of the upper urinary tract (UUT), the reported bladder recurrence rate of urothelial carcinoma is 22-47%. A single intravesical instillation of chemotherapy within 10 days following nephro-ureterectomy has the potential to decrease the risk of a bladder recurrence significantly. Despite recommendation by the European Association of Urology guideline to administer a single instillation postoperatively, the compliance rate is low because the risk of extravasation of chemotherapy. AIM: To reduce the risk of bladder cancer recurrence by a single intravesical instillation of Mitomycin immediately (within 3â¯h) before radical nephro-ureterectomy or partial ureterectomy. METHODS: Adult patients (ageâ¯≥â¯18 years) with a (suspicion of a) urothelial carcinoma of the UUT undergoing radical nephro-ureterectomy or partial ureterectomy will be eligible and will receive a single intravesical instillation of Mitomycin within 3â¯h before surgery. In total, 170 patients will be included in this prospective, observational study. Follow-up will be according to current guidelines. RESULTS: The primary endpoint is the bladder cancer recurrence rate up to two years after surgery. Secondary endpoints are: a) the compliance rate; b) oncological outcome; c) possible side-effects; d) the quality of life; e) the calculation of costs of a single neoadjuvant instillation with Mitomycin and f) molecular characterization of UUT tumors and intravesical recurrences. CONCLUSIONS: A single intravesical instillation of Mitomycin before radical nephro-ureterectomy or partial ureterectomy may reduce the risk of a bladder recurrence in patients treated for UUT urothelial carcinoma and will circumvent the disadvantages of current therapy.
