Overview
This is a prospective, single-arm study in adults with recurrent or metastatic clear cell renal cell carcinoma (ccRCC). Participants will receive standard systemic therapy (targeted therapy plus anti-PD-1 immunotherapy) and undergo dual PET/CT imaging (FDG PET/CT and a CAIX-targeted PET/CT) to map disease sites. When feasible, PET/CT-visible lesions will be treated with image-guided stereotactic ablative radiotherapy (SABR). Patients will be followed to evaluate progression-free survival, local control of treated lesions, and treatment-related adverse events (planned enrollment: \~70).
Interventions
- Radiation PETCT-guided radiation therapy
PETCT-guided radiation therapy: All patients will undergo both FDG PET/CT and CAIX PET/CT. Radiotherapy will be planned and delivered based on the imaging findings, with the goal of achieving the most comprehensive feasible (all-site) coverage whenever appropriate.
Primary outcome measures
- PFS [Time frame: 2 year]
Secondary outcome measures (2)
- local control rate [Time frame: 2 year]
- Duration of current-line systemic therap [Time frame: From first radiotherapy to change of systemic therapy due to disease progression (up to 3 years).]
