Fifty-six patients were randomly assigned to receive either one-day cisplatin, doxorubicin, and cyclophosphamide (PAC) chemotherapy (PAC-I) or five-day PAC (PAC-V) for advanced epithelial ovarian carcinoma. Follow-up has been 120 + months or to death. Ninety-one percent had either suboptimal stage III or stage IV disease and 55% had grade 2 or 3 lesions. Two patients died of toxicity and were free of disease at autopsy. A third patient died of congestive heart failure with no disease at 103 months. Additionally, eight patients had a negative second-look laparotomy, and three (37.5%) are alive with no evidence of disease (NED) 133 to 144 months after diagnosis. Five patients (62.5%) died of disease 2 to 123 months after negative second-look. Patients with optimal stage III disease had a longer median progression-free interval (PFI) and survival (33.3 and 44.5 months, respectively) than those with suboptimal or stage IV disease (16.4 and 22.5 months, respectively), and the difference in median PFI is significant (P < .02). Patients with ascites at diagnosis had a shorter median PFI and survival (14.7 and 18 months) than those without ascites (30.0 and 33.0 months). Both differences were significant (PFI, P < .04; survival, P = .005). PAC produces response rates that are superior to those obtained historically with single-agent alkylating therapy. Late recurrences after negative second-look laparotomy suggest that 5-year survival data may be inadequate in ovarian carcinoma.
