Answer

About 11% of patients develop brain metastasis during the course of their disease. Renal cell carcinoma is a radioresistant tumor, but radiation treatment of brain metastasis improves quality of life, local control, and overall survival duration. Patients with untreated brain metastasis have a median survival time of 1 month, which can be improved with glucocorticoid therapy and brain irradiation. Stereotactic radiosurgery is more effective than surgical extirpation for local control and can be performed on multiple lesions.
