" Renal cell carcinoma is a type of kidney cancer in which the cancerous cells are found in the lining of very small tubes (tubules) in the kidney.
Surgical removal of all or part of the kidney (nephrectomy) is recommended. This may include removing the bladder or surrounding tissues or lymph nodes.
Radiation therapy does not usually work for renal cell carcinoma so it is not often used. Hormone treatments may reduce the growth of the tumor in some cases.
Chemotherapy is generally not effective for treating renal cell carcinoma. The drug interleukin-2 (IL-2) is effective in a small percentage of patients, but it is very toxic. Other chemotherapy drugs have been used, but patients generally do not live long once the disease has spead outside the kidney.
A cure is unlikely unless all of the cancer is removed with surgery.
The outcome depends on how much the cancer has spread and how well it responds to treatment. The survival rate is highest if the tumor is in the early stages and has not spread outside the kidney. If it has spread to the lymph nodes or to other organs, the survival rate is much lower." (via site)
