Complete transurethral resection of bladder tumor before radical cystectomy is not a risk factor for organ-confined bladder cancer: A case-control study.

To investigate the role of complete transurethral resection of bladder tumor (TURBT) before radical cystectomy (RC) for organ-confined bladder cancer.

Data of patients who underwent RC in our center from January 2008 to December 2018 were retrospectively reviewed. Patients with >T2N0M0 disease and positive surgical margins and those who received neoadjuvant/adjuvant chemotherapy or radiotherapy were excluded. Complete TURBT was defined as no visible lesion under endoscopic examination after TURBT or in the bladder specimen after RC. Kaplan-Meier curves and log-rank tests assessed disease-free survival (DFS). Logistic and Cox regression analyses were performed to identify potential predictors.

A total of 236 patients were included in this review, including 207 males, with a median age of 61 years. The median tumor size was 3 cm, and a total of 94 patients had identified pathological T2 stage disease. Complete TURBT was correlated with tumor size (p = 0.041), histological variants (p = 0.026), and down-staging (p < 0.001). Tumor size, grade, and histological variants were independent predictors of complete TURBT. During a median follow-up of 42.7 months, 30 patients developed disease recurrence. Age and histological variants were independent predictors of DFS (p = 0.022 and 0.032, respectively), whereas complete TURBT was not an independent predictor of DFS (p = 0.156). Down-staging was not associated with survival outcome.

Complete TURBT was correlated with an increased rate of down-staging before RC. It was not associated with better oncologic outcomes for patients with organ-confined bladder cancer.
