Background Open radical cystectomy (ORC) and urinary diversion in patients with bladder cancer (BCa) are associated with significant perioperative complication risk. Objective To compare perioperative complications between robot-assisted radical cystectomy (RARC) and ORC techniques. Design, setting, and participants A prospective randomized controlled trial was conducted during 2010 and 2013 in BCa patients scheduled for definitive treatment by radical cystectomy (RC), pelvic lymph node dissection (PLND), and urinary diversion. Patients were randomized to ORC/PLND or RARC/PLND, both with open urinary diversion. Patients were followed for 90 d postoperatively. Intervention Standard ORC or RARC with PLND; all urinary diversions were performed via an open approach. Outcome measurements and statistical analysis Primary outcomes were overall 90-d grade 2–5 complications defined by a modified Clavien system. Secondary outcomes included comparison of high-grade complications, estimated blood loss, operative time, pathologic outcomes, 3- and 6-mo patient-reported quality-of-life (QOL) outcomes, and total operative room and inpatient costs. Differences in binary outcomes were assessed with the chi-square test, with differences in continuous outcomes assessed by analysis of covariance with randomization group as covariate and, for QOL end points, baseline score. Results and limitations The trial enrolled 124 patients, of whom 118 were randomized and underwent RC/PLND. Sixty were randomized to RARC and 58 to ORC. At 90 d, grade 2–5 complications were observed in 62% and 66% of RARC and ORC patients, respectively (95% confidence interval for difference, −21% to −13%; p = 0.7). The similar rates of grade 2–5 complications at our mandated interim analysis met futility criteria; thus, early closure of the trial occurred. The RARC group had lower mean intraoperative blood loss (p = 0.027) but significantly longer operative time than the ORC group (p < 0.001). Pathologic variables including positive surgical margins and lymph node yields were similar. Mean hospital stay was 8 d in both arms (standard deviation, 3 and 5 d, respectively; p = 0.5). Three- and 6-mo QOL outcomes were similar between arms. Cost analysis demonstrated an advantage to ORC compared with RARC. A limitation is the setting at a single high-volume, referral center; our findings may not be generalizable to all settings. Conclusions This trial failed to identify a large advantage for robot-assisted techniques over standard open surgery for patients undergoing RC/PLND and urinary diversion. Similar 90-d complication rates, hospital stay, pathologic outcomes, and 3- and 6-mo QOL outcomes were observed regardless of surgical technique. Patient summary Of 118 patients with bladder cancer who underwent radical cystectomy, pelvic lymph node dissection, and urinary diversion, half were randomized to open surgery and half to robot-assisted laparoscopic surgery. We compared the rate of complications within 90 d after surgery for the open group versus the ...

Upper tract recurrence is a lifelong risk in patients with bladder cancer, but most cases will be missed on routine upper tract imaging. The majority of upper tract urothelial carcinoma can be diagnosed using a combination of thorough history taking, physical examination, urine cytology and sonography, indicating that routine surveillance imaging may not be the most efficient way to detect upper tract recurrence.

• Bladder cancer patients with lamina propria invasion (T1 disease) and residual T1 disease on restaging transurethral resection of bladder tumour (re-TURBT) are at a very high risk for recurrence and progression. Despite this risk, most patients are treated with a bladder preserving approach and not immediate radical cystectomy (RC).• In this study we have shown that a quarter of patients with T1 bladder cancer and residual T1 on re-TURBT who are treated with immediate RC are found to have carcinoma invading bladder muscle at RC and 5% have lymph node metastases. We have also found that >30% of patients treated with deferred RC after initial bladder-preserving therapy harbour carcinoma invading bladder muscle and almost 20% of these patients have lymph node metastases. Thus, immediate RC should be considered in all patients with T1 bladder cancer and residual T1 on re-TURBT. Objective• To report the overall survival (OS) and cancer-specific survival (CSS) of patients with residual T1 bladder cancer on restaging transurethral resection of the bladder tumour (re-TURBT). Materials and Methods• We performed a retrospective review of 150 evaluable patients treated for T1 bladder cancer with residual T1 disease found on re-TURBT between 1990 and 2007.• Patients were treated with immediate radical cystectomy (RC) or a bladder-preserving approach (deferred or no RC). • A univariate Cox proportional hazards regression model was used to test the association between treatment approach and survival. Results• Residual T1 bladder cancer was found in 150 evaluable patients, of whom 57 received immediate RC and 93 were treated with a bladder-preserving approach. • Fourteen out of 57 patients receiving immediate RC and 8/26 patients receiving deferred RC had carcinoma invading bladder muscle in the RC specimen. Three out of 57 and 5/26 patients had lymph node metastases in the RC specimen.• Median follow-up was 3.74 years.• Thirty-nine patients died during follow-up, 16 from bladder cancer. There was no significant association between immediate RC and CSS (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.43-3.09, P = 0.8) or OS (HR 0.79, 95% CI 0.4-1.53, P = 0.5). Conclusions• Because of the low number of events we cannot conclude whether RC offers a survival advantage in patients with residual T1 bladder cancer on re-TURBT. • Since a quarter of patients had carcinoma invading bladder muscle, RC should be considered in these patients.• A larger, preferably randomized, study with longer follow-up is needed.
