Clinical Trial Summary

This is a two-arm, randomized-controlled pilot study with 2 year duration. The "intervention" refers to surveillance based on the European Association of Urology (EAU) guidelines and the "control" refers to surveillance based on the American Urological Association (AUA) guidelines.

Description:

This is a two-arm, randomized-controlled pilot study with 2 year duration. The "intervention" refers to surveillance based on the EAU guidelines and the "control" refers to surveillance based on the AUA guidelines.

Research methods: Participants who presents with non-muscle invasive bladder cancer and meets the inclusion/exclusion criteria will be given an option to participate in the study. Participants will be enrolled at the Urology Clinics at the University of Texas Health Science Center San Antonio (UTHSCSA) Medical Arts and Research Center (MARC) and South Texas Veterans Health Care System (STVHCS). Non-local site include the University of Texas Southwestern Medical Center (UTSW). The research procedures consist of urine collection, cystoscopy, and patient satisfaction and cost questionnaires. The evaluation will be done by the tumor recurrence and progression of the disease. At various time points throughout the study, urine may be obtained from the patient and banked in the Genitourinary (GU) Tissue Bank. Subjects asked to provide a urine sample(s) will be asked to sign a separate informed consent. The urine is de-identified in the lab per the Health Insurance Portability and Accountability Act (HIPAA) protocol GU Tissue Bank Institutional Review Board (IRB) # 20050234H). Patients will undergo cystoscopy in clinic (standard of care). In the intervention arm, patient surveillance cystoscopy will be performed at 3, 12 months and again at 24 months following the diagnosis of bladder cancer. Patients randomized to the control arm, will undergo surveillance cystoscopy every 3 months for 2 years following the diagnosis of bladder cancer. Because use of cytology is variable among the participating urologist, the utilization of cytology will be at the treating urologist's discretion as per usual standard care. Study duration will be 2 years from most recent biopsy. Patients will be placed on the surveillance schedule based on the length of time from their last tumor.

Intervention

Other:
• Intervention
Patients randomized into the intervention group will follow the European Urologic Association (EAU) surveillance guidelines for cystoscopy follow-ups during bladder cancer surveillance.
