Background. There is little data regarding the effectiveness of palliative radiation with conventional fractionation for metastatic\nrenal cell carcinoma (RCC), which has been described as radioresistant. We conducted a retrospective analysis of patients with\nmetastatic bony disease from RCC treated with radiation therapy at our institution. Methods. Forty patients with histologically\nconfirmed RCC with a total of 53 treatment courses were included. Pain response after radiotherapy was recorded and freedom\nfrom progression was generated using posttreatment radiographs. Patient data was analyzed to assess influence on local control.\nResults. Patients had a median age of 63. Median follow-up was 9.3 months. The most common radiation dose was 30Gy in 10\nfractions. Pain control after radiotherapy was achieved in 73.6% of patients. Increasing age was associated with nonresponse at\nthe initial pain assessment post-RT (
