Evaluating the recurrence of upper urinary tract cancer after ureteroscopy and Mitomycin C treatment

Effect of a Single Instillation of Mitomycin C on the Intravesical Recurrence Rate After Ureteroscopy for Upper Tract Urothelial Carcinoma: A Prospective, Multicenter Study

Observational Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT05731622

This study is testing if a single treatment with Mitomycin C after ureteroscopy can help prevent the return of upper urinary tract cancer in patients over two years.

What this trial studies

This observational study aims to assess the rate of intravesical recurrence (IVR) following ureteroscopy for upper tract urothelial carcinoma (UTUC) in patients who receive a single instillation of Mitomycin C (SI-MMC). It will track the total and time to IVR over a two-year period and compare these outcomes with a historical cohort that did not receive SI-MMC. Additionally, the study will evaluate the effectiveness of SI-MMC in patients who undergo further treatment, such as endoscopy or radical nephroureterectomy. The study will also explore predictive factors for IVR rates.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a suspicion of non-metastatic upper urinary tract urothelial carcinoma who are scheduled for ureteroscopy and SI-MMC.

Not a fit: Patients with a history of bladder cancer, concurrent bladder tumors, or those who cannot undergo histological evaluation during the procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into improving treatment outcomes and reducing recurrence rates for patients with upper urinary tract carcinoma.

How similar studies have performed: While this approach is being evaluated in this specific context, similar studies have shown promise in reducing recurrence rates with Mitomycin C in other settings.
