Treatment of renal cell carcinoma with ionizing radiation is currently on the border between the modern concept. Radiotherapy, which always belonged to the domain of palliative treatment of renal carcinoma, finds new application in the treatment of primary and metastatic lesions in the form of ablative doses exceeding traditionally reported radioresistance. The use of modern techniques of stereotactic irradiation offers patients an effective gentle treatment with a high probability of local control and prolonged symptom-free period. Hand in hand with targeted medical treatment further contributes to the treatment of metastatic disease. Palliative radiotherapy still forms an integral part of care for symptomatic patients.
