Non-surgical treatment for kidney tumors using targeted radiation therapy

Phase II Study: Stereotactic Ablative Radiotherapy for Renal Tumors

Not applicable Interventional University Health Network, Toronto · NCT03747133

This study is testing a new non-surgical radiation treatment for kidney tumors to see if it can help patients who can't have surgery feel better and improve their quality of life.

What this trial studies

This study investigates the use of Stereotactic Ablative Radiosurgery (SABR) as a non-invasive treatment option for patients with renal tumors, particularly those who are not suitable candidates for surgery. The approach involves delivering high doses of radiation directly to the tumor while minimizing damage to surrounding healthy tissue. Patients will undergo assessments before and after treatment, with follow-up evaluations every four months for up to two years, during which they will complete quality of life questionnaires and receive standard imaging. The goal is to provide an effective alternative treatment for renal cell carcinoma, especially in older patients.

Who should consider this trial

Good fit: Ideal candidates include patients with solid kidney masses that are inoperable due to high surgical risk or personal choice, and who have a performance status of 0-3.

Not a fit: Patients with multiple active metastases, end-stage renal failure, or certain hereditary syndromes will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a viable non-surgical option for patients with renal tumors, improving their quality of life and treatment outcomes.

How similar studies have performed: Other studies have shown promising results with SABR for various tumors, indicating potential success for this approach in renal tumors as well.
