What this Trial Is About

Bladder cancer (BC) is the 6th most common tumor in Europe, with over 540,000 new cases globally each year. While 75% of cases are non-muscle-invasive and treated bladder-preservingly, muscle-invasive, non-metastatic BC requires radical cystectomy (RC), often with neoadjuvant chemotherapy. RC has one of the highest complication rates in urology, and rehabilitation focuses on mitigating functional impairments, restoring physical and mental capacity, and enabling a swift return to daily life. The ERAS (Enhanced Recovery After Surgery) protocol has shown benefits in reducing hospital stays without increasing complications in RC. Prehabilitation studies in cancer patients have demonstrated improvements in strength and fitness, though without significant reductions in complications or mortality. This prospective randomized study, conducted over three years at the University of Munich, will evaluate the effect of preoperative physical activity on perioperative morbidity (primary endpoint). Secondary endpoints include quality of life, hospital stay, mortality, and postoperative physical activity. The intervention group will target 8,000-10,000 daily steps for four weeks preoperatively, monitored via pedometers. Follow-ups will assess physical activity and quality of life at specific intervals pre- and post-surgery.
