OBJECTIVE: To compare the prognoses associated with positive surgical margins (PSMs) according to their urethral, ureteric and/or soft tissue locations in patients with pN0 M0 bladder cancer who have not undergone neoadjuvant chemotherapy. PATIENTS AND METHODS: A retrospective, case-control study was conducted between 1991 and 2011 using data from 17 academic centres in France. A total of 154 patients (cases) with PSMs met the eligibility criteria and were matched according to centre, pT stage, gender, age and urinary diversion method with a population-based sample of 154 patients (controls) from 3651 patients who had undergone cystectomies. The median follow-up period was 23.9 months. Multivariable Cox regression analysis was used to test the effects of PSMs on local recurrence (LR)-free survival, metastatic recurrence (MR)-free survival and cancer-specific survival (CSS). RESULTS: The 5-year LR-free survival and CSS rates of patients with urethral and soft tissue PSMs were lower than those in the control group. A significant decrease in CSS was associated with soft tissue PSMs (P = 0.003, odds ratio = 0.425, 95% confidence interval 0.283-0.647). The prognosis was not affected in cases of ureteric PSMs. CONCLUSIONS: Soft tissue PSMs were associated with poor CSS rates in patients with pN0 M0 bladder cancer. A correlation between urethrectomy and a reduction of the risk of LR in a urethral PSM setting was observed.
