This study focuses on people who have renal cell cancer that has spread beyond the kidney and for whom surgery is not currently recommended (or who have chosen not to have surgery). The study aims to determine whether the addition of radiation therapy to the usual immune therapy can increase the time that the patient’s renal cancer does not get worse. The usual approach for patients with metastatic renal cell cancer who are not having surgery is treatment with immune therapy alone or immune therapy plus a targeted therapy drug called a VEGF inhibitor. The addition of radiation therapy to the usual treatment may stabilize the patient’s cancer or possibly cause it to shrink, but it could also cause side effects. Researchers will evaluate whether the study approach increases the time without cancer progressing by 6 months or more compared to the usual approach. The study has 2 groups, and patients are randomly assigned to 1 of the 2 groups. Group 1 will receive the usual immune therapy as an infusion through a vein in the arm, and if they also receive a VEGF drug, they will receive this as a pill taken orally. Group 2 will receive radiation therapy plus the usual immune therapy.
