AB152. Combination of intravesical chemotherapy and Bacillus Calmette-Guerin versus Bacillus Calmette-Guerin monotherapy in intermediate- and high-risk non-muscle invasive bladder cancer: a systematic review and meta-analysis

Objective Urothelial carcinoma of the bladder has become a major cause of morbidity, mortality, and health-related costs. There is still no standard instillation therapy against bladder cancer. A meta-analysis was conducted to evaluate the efficacy and toxicity of adding chemotherapy to Bacillus Calmette-Guerin (BCG) in intermediate- and high-risk nonmuscle invasive bladder cancer (NMIBC).
