Treatment of advanced ovarian cancer with cis-dichlorodiammine platinum in combination with cyclophosphamide. An E.C.O.G. pilot study.

Twenty patients with Stage III and IV carcinoma of the ovary have been treated with a combination of cyclophosphamide and cis-platinum given every 3 weeks. Regarding toxicity, this combination probably included a too-high dose of CTX (1.1 g/m2 every 3 weeks). The response rate was 75% (15/20) but with a significant duration only for those patients who achieved a complete response (7/20). It was seen that, as usual, patients who have undergone extensive reductive surgery are more likely to respond. The regimen described gives results comparable to those of more aggressive combinations but did not achieve significant control of the disease.
