[Combination chemotherapy of vincristine, ifosfamide and peplomycin in patients with reactivated prostatic cancer].

Ten patients with reactivated stage D prostatic cancer were treated with the combination therapy of vincristine, ifosfamide and peplomycin (VIP therapy). This treatment gave a good relief of bone pain in 4 out of 8 patients (50%) and improvement of dysuria in 2 out of 6 patients (33%), but objective responses of primary and metastatic lesions were poor. The over-all response rate was 20% by Karnofsky's category of response, 10% by the response criteria of Shida et al., 50% by National Prostatic Cancer Project criteria in the United States and 10% by the response criteria of Koyama and Saito's group. The toxicity of VIP therapy was mild to moderate except for hepatic insufficiency shown in one case.
