THE TREATMENT OF METASTATIC RENAL CELL CARCINOMA

Of 57 patients with renal cell carcinoma admitted to our hospital or a collaborating hospital from January 1966 through December 1980, 16 patients were diagnosed to have stage IV cancer. The therapeutic results of these 16 patients are presented in this paper. The patients were 4 females and 12 males, and ranged in age from 48 to 71 years, with an average of 59.9 years. Metastatic lesions were seen in the lungs in 6 patients, in the bones in 3 patients, in the liver in 3 patients, in both the lungs and bones in 2 patients, in the distant lymph nodes in 2 patients, and in the skin in 1 patient. Palliative nephrectomy was performed on 10 patients. Their survival rates were 50.0% at 6 months, 40.0% at 1 year and 28.6% at 2 years. Four out of 6 patients given Provera, Futraful and Picibanyl after the palliative nephrectomy survived longer than those given other treatments.
