From July 1, 1979 to June 30, 1983, 136 consecutive patients with category M0 renal cell cancer who had undergone transperitoneal radical nephrectomy at 5 centers entered a prospective randomized trial to compare 500 mg. adjuvant medroxyprogesterone 3 times a week for 1 year to no treatment. Sex steroid hormone receptors also were studied in the renal tumor and in the surrounding healthy parenchyma with the dextran-coated charcoal technique. After a median followup period of 3 years (range 13 to 60 months) 30 of 121 evaluable patients (24.8 per cent) experienced relapse, usually in the lung or bones. Relapses occurred in 15 of 58 evaluable patients in the adjuvant treatment group (25.8 per cent) and 15 of 63 evaluable controls (23.8 per cent). The disease recurred more frequently (35.1 per cent) in the 57 patients with no receptors in the tumor than in the 45 with at least 1 receptor (17.8 per cent). These results were independent of adjuvant therapy. After a median 3-year followup, adjuvant medroxyprogesterone acetate was of no therapeutic benefit in patients who had undergone radical nephrectomy and the side effects of the therapy were evident in more than 50 per cent of the patients.
