Abstract
Patients with advanced ovarian carcinoma, Stage III or IV (International Federation of Gynaecology and Obstetrics), were randomized to primary chemotherapy with doxorubicin (Adriamycin) and cisplatin plus or minus hexamethylmelamine, and cyclophosphamide (CHAP). The four-drug CHAP regimen produced a 57% complete clinical response rate and a 26% partial response rate for clinically evaluable patients. The median survival of CHAP patients is 25 months. The two-drug Adriamycin-cisplatin (AP) regimen produced a 43% complete response rate and a 35% partial response rate. The median survival is 18 months. The four-drug regimen produced a significantly longer median survival (28 versus 18 months) for patients with poorly differentiated tumors than for patients with well-differentiated tumors on either treatment. Examination of treatment failure or death by treatment, histology, and size of largest residual tumor and comparison to similar patients treated with AP in this and two preceding controlled trials also suggest that CHAP is superior to AP for patients with poorly differentiated tumors.
