Randomised trial comparing combinations of cyclophosphamide and cisplatin without or with doxorubicin or 4'-epi-doxorubicin in the treatment of advanced ovarian cancer

Abstract

Forty-eight patients with FIGO stage III and IV epithelial carcinomas of the ovary were entered in this randomised trial. Radical surgery was performed and no residual tumor with a diameter greater than 2 cm was left behind. Of these patients 62.5% (10/16) had a complete or partial response on cyclophosphamide + cisplatin (CP) 87.5% (14/16) on cyclophosphamide + doxorubicin + cisplatin (CAP) and cyclophosphamide + 4'-epi-doxorubicin + cisplatin (CEP). The median time to progression was 3.5 months on CP, 12.5 months on CAP and 11.0 months on CEP. Patients treated with CAP combination chemotherapy had generally longer progression-free survival (log rank chi 2 = 5.4; P = 0.04). No significant difference was found, however, between patients on CAP and CEP. The median survival times were 12.5 months on CP, 26.5 months on CAP and 14.0 months on CEP. Patients treated with CAP combination chemotherapy had generally longer survival (logrank chi 2 = 9.08; P = 0.0099). No significant difference was found, however, between patients on CAP and CEP in terms of survival. Asymptomatic mild-to-moderate laboratory test toxicity occurred in 6-12% of patients on CP, 6-12% on CAP and no toxicity of this type and grade on CEP. Nausea and vomiting were also less severe and less frequent in the CEP group. Cardiotoxicity was seen in 12.5% (2/16) only in the CAP group.
