Role of immunotherapy in bacillus Calmette-Guerin-unresponsive non-muscle invasive bladder cancer.

ABSTRACT: Intravesical instillation of live attenuated bacillus Calmette-Guérin (BCG) is the gold standard for patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-failures include a heterogenous population of patients who share a designation of disease recurrence or progression following BCG and include patients with complete unresponsiveness to BCG, patients who respond initially but develop relapse and, in some cases, patients who are intolerant to BCG due to side effects. Given the efficacy and relatively rapid approval of several monoclonal antibodies against PD-L1 or PD-1 for advanced and metastatic bladder cancer, the role of these checkpoint inhibitors in BCG-relapsing disease at various disease stages is under consideration.
