ABSTRACT
BACKGROUND:
The purpose of this study was to compare the efficacy of 2 bacillus Calmette-Guérin (BCG) strains, BCG-Tice and BCG-Moreau, in the treatment of non-muscle-invasive bladder cancer (NMIBC). MATERIALS ANDMETHODS:
We retrospectively reviewed clinical data from patients treated with BCG for NMIBC at 3 academic centers. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves and Cox proportional hazards regression analyses were used to compare recurrence-free (RFS) and progression-free survival (PFS) of patients in the 2 treatment groups. In addition, we performed exploratory analyses of treatment effect according to the receipt of adequate BCG treatment, high-risk disease, age, gender, smoking status, pathologic stage, and pathologic grade.RESULTS:
A total of 321 (48.6%) patients were treated with BCG-Tice and 339 (51.4%) with BCG-Moreau. IPTW-adjusted Cox proportional hazard regression analysis did not show a difference in RFS (hazard ratio, 0.88; 95% confidence interval, 0.56-1.38; P = .58) or PFS (hazard ratio, 0.55; 95% confidence interval, 0.25-1.21, P = .14) between BCG-Tice and BCG-Moreau. On subgroup analyses, we could not identify an association of BCG strain with outcomes.CONCLUSIONS:
There was no difference in RFS and PFS between BCG-Tice and BCG-Moreau strains in the adjuvant treatment of NMIBC. However, we confirmed the importance of maintenance therapy for achieving a sustainable response in patients with intermediate- and high-risk NMIBC.Palavras-chave
