Bladder sparing options for muscle-invasive bladder cancer.

PURPOSE OF REVIEW: This review critically evaluates the current state of bladder-sparing options in muscle-invasive bladder cancer (MIBC) and provides an overview of future directions in the field.

RECENT FINDINGS: Bladder-sparing treatments have emerged as viable alternatives to radical cystectomy (RC) for selected patients with MIBC, especially in those who are unfit for RC or elect bladder preservation. Numerous studies have assessed the efficacy of trimodal therapy (TMT), with outcomes comparable to RC in a subgroup of well selected patients. Combining immunotherapy with conventional treatments in bladder-sparing approaches can yield promising outcomes. Current research is making significant progress in optimizing treatment protocols by exploring new combinations of systemic therapy agents, innovative drug delivery methods, and biomarker-based approaches. Furthermore, clinical markers of response are being tested to ensure adequate response assessment.

SUMMARY: Bladder preservation promise to offer a viable alternative to RC for selected patients with MIBC with the potential to improve patient quality of life. Careful patient selection and ongoing research are essential to optimize patient selection, response assessment, and salvage strategies. As evidence continues to evolve, the role of bladder preservation in MIBC is likely to expand, providing patients with more treatment options tailored to their needs and preferences.
