Guiding Value of Urinary Tumor DNA Testing in Repeat Transurethral Resection of Non-Muscle-Invasive Bladder Cancer

Participants with NMIBC who have undergone initial TURBT will not receive utDNA testing and will undergo a second transurethral resection of bladder tumor (re-TURBT) within 2-6 weeks after the initial surgery, in accordance with current clinical guidelines.

"Participants with NMIBC who have undergone initial TURBT will receive urine tumor DNA (utDNA) testing.~If utDNA is positive, the patient will undergo a second transurethral resection of bladder tumor (re-TURBT) within 2-6 weeks after the initial surgery.~If utDNA is negative, re-TURBT will be omitted and patients will proceed to guideline-based adjuvant therapy or surveillance."
