Testing the Addition of Stereotactic Radiation Therapy With Immune Therapy for the Treatment of Patients With Unresectable or Metastatic Renal Cell Cancer, SAMURAI Trial
Recruiting
This phase II trial tests whether the addition of radiation to the primary tumor, typically given with stereotactic ablative radiation therapy (SABR), in combination with standard of care immunotherapy improves outcomes in patients with renal cell cancer that is not recommended for surgery and has spread from where it first started (primary site) to other places in the body (metastatic). Radiation therapy uses high energy photons to kill tumor cells and shrink tumors. Stereotactic body radiation... Read More
