Seven patients with gynecological cancer were treated with cis-platinum. Cis-platinum at 50 mg/m2 was administered by intravenous infusion for 2 hours, followed by 2,000 ml of intravenous fluid. This treatment was repeated every three weeks. Five of the seven patients were evaluable. These patients included those with ovarian cancer (3 cases), metastatic ovarian cancer (1 case), and endometrial cancer (1 case). One patient attained a complete response, two a partial response, and two showed progressive disease. The response rate for both complete and partial response was 60%. Gastrointestinal symptoms were most frequently found. Nephrotoxicity was generally mild, but one patient had to discontinue cis-platinum treatment due to severe nephrotoxicity. Cis-platinum treatment is considered to be effective and useful for gynecological cancer. Second-look operation and two-channel chemotherapy were also discussed in this paper.
