Treatment principles Surgical surgery is the treatment of choice for limited and locally progressive renal cancer. Immunotherapy or chemotherapy or (and) radiotherapy based on immunotherapy or difluorodeoxycytidine (trade name gemcitabine, keyselect) is recommended for patients with residual tumor after surgery. In contrast, metastatic renal cancer should be treated with a combination of mainly internal medicine. Treatment methods Surgical treatment Radical nephrectomy: It is the only method that has been recognized as a possible cure for kidney cancer and is suitable for limited kidney cancer (T1, T2) and locally progressive kidney cancer (T3, T1N1, T2N1). Classical radical nephrectomy includes: perinephric fascia, perinephric fat, affected kidney, ipsilateral adrenal gland, hilar lymph nodes and ureter above the iliac vascular division. The modern view is that if the clinical stage is I or II, the tumor is located in the middle and lower part of the kidney.
