進行前立腺癌に対するEtoposide,Ifosfamide,Peplomycin併用化学療法の治療成績について

Abstract

Between August, 1986 and August, 1992, 16 combination chemotherapies with etoposide (100 mg/body, day 1-5), ifosfamide (50 mg/kg, day 1, 3, 5), peplomycin (5 mg/body, day 1-5) were performed on 13 patients with endocrine therapy-relapsed advanced prostatic cancer. Seven trials were performed on 5 patients who received DESP (diethylstilbestrol diphosphate) (500 mg/body, day 1-5) with the chemotherapy. In 9 trials performed on 9 patients who did not receive DESP, there was no response case. In 7 trials with DESP, one trial had a partial response (PR) (14%) and 4 remained objectively stable (stable) (57%). As to adverse effects, myelosuppression was observed in all trials but there was no lethal toxicity. The one-year survival rate of these patients treated with the chemotherapy alone and combined DESP were both about 20%. Therefore we should find a more effective treatment for endocrine relapsed prostatic cancer.
