Seven patients were entered in this study between November 1978 and February 1983. All patients had histologically proven renal cell carcinoma with widespread metastases. Patients ranged in age from 27 to 69 years, with an average of 54 years. All those studied had measurable radiological lesions of malignant disease. One patient was treated with only CDDP and the other 6 patients were treated with CDDP and other anti-cancer drugs (vinblastine, ifosfamide, bleomycin and/or adriamycin). Total doses of CDDP ranged from 20 to 250 mg, with an average of 99 mg. Four cases showed no change and 3 patients had progressive disease. Symptomatic improvement was obtained in only 2 patients. Management of metastatic renal cell carcinoma is discussed briefly.
