Overview
Brief Summary
This phase III randomized controlled trial evaluates the efficacy of stereotactic body radiation therapy (SBRT) in oligometastatic renal cell carcinoma. The study aims to determine if the addition of SBRT to standard systemic therapy prolong survival compared to the standard systemic therapy alone. In addition, the study will explore the impact of this combined modality therapy on patients' toxicity and quality of life. The researchers will compare SBRT plus standard systemic therapy to standard systemic therapy alone, which is targeted agents and immunotherapy in this case, to determine if SBRT could prolong survival.
Detailed Description
PRIMARY OBJECTIVES: To compare the progression-free survival (PFS) between patients receiving SBRT + standard systemic therapy versus standard systemic therapy alone. SECONDARY OBJECTIVES: I. To compare the overall survival (OS) between patients receiving SBRT + standard systemic therapy versus standard systemic therapy alone. II. To compare the cancer specific survival (CSS) between patients receiving SBRT + standard systemic therapy versus standard systemic therapy alone. III. To estimate the local control (LC) rate of SBRT. IV. To compare the post-treatment progression-free survival (post-treatment PFS) between patients receiving SBRT + standard systemic therapy versus standard systemic therapy alone. V. To evaluate treatment-related toxicity after adding SBRT based on patient-reported outcomes and researcher reported adverse events. VI. To compare the quality of life between patients treated with SBRT or not using EQ-5D-5L, FKSI-DRS and FKSI-19. OUTLINE: Patients are randomized to either Control arm or SBRT arm. Control arm: Patients receive standard of care systemic therapy on study. SBRT arm: Patients undergo SBRT to all metastatic sites in addition to standard of care systemic therapy on study. Patients periodically receive computed tomography (CT), positron emission tomography (PET)/CT, and/or magnetic resonance imaging (MRI) throughout the trial.

Arms & Interventions
SBRT arm
Patients undergo SBRT to all metastatic sites in addition to standard systemic therapy. Patients should complete radiotherapy for all lesions within 6 months of enrollment, preferably within the first 3 months.
