N2 - BACKGROUND: Patients with non-muscle-invasive bladder cancer with an intermediate or high risk need adjuvant intravesical therapy after surgery. Based largely on meta-analyses of previously published results, guidelines recommend using either bacillus Calmette-Guérin (BCG) or mitomycin C (MMC) in these patients. Individual patient data (IPD) meta-analyses, however, are the gold standard. OBJECTIVE: To compare the efficacy of BCG and MMC based on an IPD meta-analysis of randomised trials. DESIGN, SETTING, AND PARTICIPANTS: Trials were searched through Medline and review articles. The relevant trial investigators were contacted to provide IPD. MEASUREMENTS: The drugs were compared with respect to time to recurrence, progression, and overall and cancer-specific death. RESULTS AND LIMITATIONS: Nine trials that included 2820 patients were identified, and IPD were obtained from all of them. Patient characteristics were 71% primary, 54% Ta, 43% T1, 25% G1, 58% G2, and 16% G3, and 7% had prior intravesical chemotherapy. Based on a median follow-up of 4.4 yr, 43% recurred. Overall, there was no difference in the time to first recurrence (p=0.09) between BCG and MMC. In the trials with BCG maintenance, a 32% reduction in risk of recurrence on BCG compared to MMC was found (p
