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.

Who should consider this trial

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

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

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