ABSTRACT
Bacillus Calmette-Guérin (BCG) therapy is the standard of care in the treatment of high-risk non-muscle invasive bladder cancer (NMIBC). In the absence of a response to BCG and persistent high-grade disease, cystectomy is recommended depending on the clinical risk. A variety of targeted therapy approaches, which aim at immune- and gene-based molecular targets, such as PD-(L)1 and FGFR, are currently being investigated in randomized studies for BCG-unresponsive NMIBC. Furthermore, novel forms of application for instillation therapy, such as the TAR device, in combination with gemcitabine or erdafitinib are being investigated in clinical trials in order to extend the duration of action of the active substance on the urothelium. Thus, there are now many developments that could make bladder-preserving therapy with comparable survival data possible as an alternative to BCG or in the event of BCG failure. In the future, it will be necessary to clarify how BCG response can be predicted by using molecular markers and how to define risk groups that should primarily be given an alternative therapy to BCG.
