were analyzed using the Kaplan-Meier method and Cox regression analysis. RESULTSThe median age of patients was 68 years with a mean (median) follow-up time of 35 (29) months. The 30, 60 and 90-day postoperative mortality rates were 1.3%, 2.6% and 3.2%, respectively. The 5-year overall, recurrencefree and cancer-specific survival was 57%, 48% and 67%, respectively, with a local recurrence rate of 6%. Pathological stage distribution was < pT2N0, n = 498 (23%); pT2N0, n = 365 (17%); pT3N0, n = 463 (21%); pT4N0, n = 170 (8%); and pTxN + , n = 507 (23%). Only 3.1% of patients received neoadjuvant chemotherapy and 19.4% received adjuvant chemotherapy. On multivariate analysis, lower pathological stage, negative surgical margins, receipt of adjuvant chemotherapy, performance of pelvic lymphadenectomy and an absence of smoking were associated with prolonged disease-specific and overall survival.

This initiative was undertaken in response to concerns regarding the variation in management and in outcomes of patients with bladder cancer throughout centres and geographical areas in Canada. Population-based data have also revealed that real-life survival is lower than expected based on data from clinical trials and/or academic centres. To address these perceived shortcomings and attempt to streamline and unify treatment approaches to bladder cancer in Canada, a multidisciplinary panel of expert clinicians was convened last fall for a two-day working group consensus meeting. The panelists included urologic oncologists, medical oncologists, radiation oncologists, patient representatives, a genitourinary pathologist, and an enterostomal therapy nurse. The following recommendations and summaries of supporting evidence represent the results of the presentations, debates, and discussions. Methodology

Study Type – Prognosis (cohort) Level of Evidence 2a What's known on the subject? and What does the study add? Radical cystectomy with pelvic lymph node dissection is recognized as the standard of care for carcinoma invading bladder muscle and for refractory non‐muscle‐invasive bladder cancer. Owing to high recurrence and progression rates, a two‐pronged strict surveillance regimen, consisting of both functional and oncological follow‐up, has been advocated. It is also well recognized that more aggressive tumours with extravesical disease and node‐positive disease recur more frequently and have worse outcomes. This study adds to the scant body of literature available regarding surveillance strategies after radical cystectomy for bladder cancer. In the absence of any solid evidence supporting the role of strict surveillance regimens, this extensive examination of recurrence patterns in a large multi‐institutional project lends further support to the continued use of risk‐stratified follow‐up and emphasizes the need for earlier strict surveillance in patients with extravesical and node‐positive disease. OBJECTIVES To review our data on recurrence patterns after radical cystectomy (RC) for bladder cancer (BC). To establish appropriate surveillance protocols. PATIENTS AND METHODS We collected and pooled data from a database of 2287 patients who had undergone RC for BC between 1998 and 2008 in eight different Canadian academic centres. Of the 2287 patients, 1890 had complete recurrence information and form the basis of the present study. RESULTS A total of 825 patients (43.6%) developed recurrence. According to location, 48.6% of recurrent tumours were distant, 25.2% pelvic, 14.5% retroperitoneal and 11.8% to multiple regions such as pelvic and retroperitoneal or pelvic and distant. The median (range) time to recurrence for the entire population was 10.1 (1–192) months with 90 and 97% of all recurrences within 2 and 5 years of RC, respectively. According to stage, pTxN+ tumours were more likely to recur than ≥pT3N0 tumours and ≤pT2N0 tumours (5‐yr RFS 25% vs. 44% vs. 66% respectively, P < 0.001). Similarly, pTxN+ tumours had a shorter median time to recurrence (9 months, range 1–72 months) than ≥pT3N0 tumours (10 months, range 1–70 months) or ≤pT2N0 tumours (14 months, range 1–192 months, P < 0.001). CONCLUSIONS Differences in recurrence patterns after RC suggest the need for varied follow‐up protocols for each group. We propose a stage‐based protocol for surveillance of patients with BC treated with RC that captures most recurrences while limiting over‐investigation.
