A Study Comparing the Necessity of a Second Transurethral Resection in High-Risk Non-Muscle-Invasive Bladder Cancer Patients With Negative Results From Post-Initial Resection Urine Genome-Wide Low-Depth Sequencing

This study is a prospective, randomized, multicenter clinical trial aiming to enroll 428 patients with non-muscle-invasive bladder cancer (NMIBC) from the Department of Urology at Jiangsu Provincial People's Hospital and its affiliated centers, who have undergone their initial transurethral resection and are scheduled for a second resection. Within 1-6 weeks after the first resection and prior to the second resection, 100ml of routine urine will be collected and sent within 24 hours to Beijing Genetron Health Clinical Laboratory Co., Ltd. for the extraction of urinary sediment DNA, which will then undergo genome-wide low-depth sequencing. Patients with positive test results will proceed with the second resection, while those with negative results will be randomly assigned in a 1:2 ratio to either the intervention group, which will not undergo a second resection, or the control group, which will undergo the second resection. All enrolled patients will be followed up for two years. The study will statistically analyze and compare the two-year recurrence-free survival rates between the two groups and evaluate the predictive capability of the test results for follow-up recurrence.
