Ideal candidates are asymptomatic individuals over 50 years old with a single solid renal mass less than 2 cm.

Probably not a fit

Patients with a history of renal neoplasia, metastatic disease, or significant comorbidities may not benefit from this study.

What this trial studies

This study focuses on the active surveillance of small renal masses (SRMs) in asymptomatic patients over 50 years old. Participants diagnosed with a single solid renal mass of 2 cm or less will be monitored over a five-year period, with evaluations at regular intervals to assess tumor progression. The study aims to determine the safety and efficacy of this non-invasive approach compared to immediate surgical intervention. Follow-up will continue for up to ten years to track long-term outcomes.

Why it matters

Potential benefit: If successful, this approach could reduce unnecessary surgeries and associated complications for patients with small kidney tumors.

How similar studies have gone: Previous studies on active surveillance for small renal masses have shown promising results, indicating that this approach may be viable for select patients.
