[Treatment of hormonal refractory adenocarcinoma of the prostate with ifosfamide (IFM) and the combination of vincristine ifosfamide and peplomycin (VIP)].

Nineteen patients with hormonal refractory adenocarcinoma of the prostate were treated with ifosfamide (IFM) and the combination of vincristine, ifosfamide and peplomycin (VIP). Nine of them were treated with IFM, and nine with VIP, and one with IFM and also VIP. In the case of the IFM therapy, the over-all response rate was 0% by the Karnofsky's category of response, 20% by the response criteria of Shida et al., 50% by the National Prostatic Cancer Project (NPCP) criteria, and 0% by the response criteria of Koyama and Saito. In the case of the VIP therapy, the over-all response rate was 30% by the Karnofsky's category, 30% by the response criteria of Shida et al., 70% by the NPCP criteria and 20% by the response criteria of Koyama and Saitoh. The one-year survival rates of these patients treated with IFM and VIP were both about 20%. Only one patient treated with VIP therapy showed a partial response. Therefore, a more effective regimen for hormonal refractory adenocarcinoma of the prostate must be developed.
