CAP, a multiple-drug combination therapy using cyclophosphamide (750 mg/m2), adriamycin (20-30 mg/m2) and cisplatin (50-75 mg/m2), was applied to 69 cases of epithelial ovarian cancer. The results of this therapy were compared with those of FAM (involving 5-fluorouracil, cyclophosphamide and mitomycin C) in 47 cases of the same cancer, retrospectively. The 5-year survival rate was 61.6% for cases treated with CAP and 56.3% for cases treated with FAM. All 9 patients at stage Ia treated with CAP are free of disease, however, 3 patients out of 13 at stage Ia treated with FAM experienced a recurrence of the disease and died. In stage III and IV cases with detectable lesions, a response was observed in 61.3% (19/31) treated with CAP and in 10.5% (2/19) treated with FAM.
