Comparing urine tests to cystoscopy for monitoring bladder cancer

A Randomized Cross-Over Study to Evaluate Patient Preference and Satisfaction With Urine-based Molecular Testing Versus Cystoscopy for Surveillance of Nonmuscle Invasive Bladder Cancer (NMIBC)

Observational Mayo Clinic · NCT06126796

This study is trying to see if people with nonmuscle invasive bladder cancer prefer a simple urine test over the more invasive cystoscopy for monitoring their condition.

What this trial studies

This study evaluates patient preferences between urine-based molecular testing (CxBladder Monitor) and traditional cystoscopy for surveillance of nonmuscle invasive bladder cancer (NMIBC). The urine test is a noninvasive method that analyzes biomarkers related to cancer recurrence, while cystoscopy involves a more invasive examination of the bladder. Participants will provide urine samples and complete online surveys to share their experiences and preferences regarding these two monitoring methods.

Who should consider this trial

Good fit: Ideal candidates are individuals with a history of nonmuscle invasive bladder cancer who have been disease-free for at least six months and can provide urine samples.

Not a fit: Patients with non-urothelial bladder cancer or those with significant variant histology may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a less invasive and more patient-friendly approach for monitoring bladder cancer recurrence.

How similar studies have performed: Other studies have explored urine-based tests for cancer monitoring, showing promising results, but this specific comparison with cystoscopy is relatively novel.
