Non-muscle-invasive bladder cancer NMIBC is a type of bladder tumor that affects the inner lining of the bladder without invading the muscle layer. This research aims to collect and analyze real-world data on how NMIBC is managed and followed up in clinical practice across France. The study seeks to assess the performance of urine tests used to detect tumor recurrence and to understand variations in treatment and patient outcomes. The study is observational and involves collecting medical data from patients being monitored for NMIBC, including results from urine biomarker tests done before biopsies or resections. Urologists participating in the French Urology Association will record findings from regular bladder endoscopic exams and urine test results during routine care visits. Data analysis will focus on the accuracy of urine tests in predicting tumor recurrence and how this varies by tumor characteristics and prior treatments. Participants will have their medical history, treatments, and urine test results entered into a registry at enrollment. During follow-up visits scheduled as part of their personalized care, data on bladder exams and urine tests will be collected. Researchers will evaluate outcomes such as recurrence-free survival and the diagnostic value of urine biomarkers over a five-year period. The study plans to include around 8,000 patients over six years to improve understanding of NMIBC management and follow-up.
