TI - Long term control and preservation of renal function after multiple courses of stereotactic body radiation therapy for renal cell carcinoma T2 - Canadian Journal of Urology PY - 2019 VL - 26 IS - 2 SN - 1488-5581 AB - Renal cell carcinoma (RCC) is usually treated with surgery, with or without systemic therapy. For select patients, stereotactic body radiation therapy (SBRT) may be a suitable alternative. Although many reports exist on the successful use of SBRT, very few have described long term outcomes with regard to disease progression and renal function. We report a rare case of a single patient with primary, metastatic, and locally recurrent renal cell carcinoma who was successfully treated with SBRT. The patient has been disease-free for 8 years since treatment, with stable renal function even after two courses of SBRT to her solitary functioning kidney.
