[Therapy of renal cell carcinoma. 1. Hormonal therapy].

Sixty eight patients with renal cell carcinoma were treated at our University in 1968 approximately 1983. The prognosis of these patients was studied retrospectively. Sixty six patients had also been receiving treatment with chemotherapy or radiotherapy except 3 cases after radical nephrectomy. Thirty five of the patients with Stage I approximately N renal cell carcinoma were treated with hormonal therapy using chlormadinone acetate (CMA) or medroxyprogesterone acetate (MPA). CMA was used prophylactically in 21 patients with Stage I approximately IIIA renal cell carcinoma and who had undergone radical nephrectomy. Metastasis was noted in 3 cases in this prophylactic CMA group (21 cases) and 4 cases in the control group (19 cases). No significant difference between these two groups was observed statistically. In the advanced group with Stage IIIC-IV renal cell carcinoma (11 cases), only one case with a complete response was noted after CMA combination therapy.
