59P Efficacy of immune checkpoint inhibitors in BCG-unresponsive non-muscle invasive bladder cancer: A systematic review and meta-analysis

2025Open accessAlexandria University

Abstract

Bladder cancer, the most common malignancy of the urinary tract, is divided into non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC). Intravesical Bacillus Calmette-Guérin (BCG) therapy is the standard treatment for high-risk NMIBC, but recurrence and progression remain significant challenges. This review aims to explore immune checkpoint inhibitors (ICIs), particularly pembrolizumab, as emerging therapies for BCG-unresponsive NMIBC.
