The immunotherapy for kidney cancer often involves the use of interferons or interleukins, and the results are generally satisfactory. The effects of radiotherapy and chemotherapy for kidney cancer are not very certain. Typically, after kidney cancer is diagnosed, radical nephrectomy is performed. During the surgery, adequate exposure is essential. The renal hilum should be ligated first to prevent cancer cells from being squeezed into the bloodstream during surgery. It is also necessary to remove the fascia and fat around the kidney, along with the lymph nodes at the renal hilum. Combining these surgical measures with immunotherapy usually yields very ideal results.
