title: Long-term survival after chemotherapy for advanced epithelial ovarian carcinoma.
abstract: Four hundred twenty-nine patients were entered into four prospective randomized clinical studies between January 1, 1973, and July 1, 1979. The records of 395 of these were analyzed to determine the proportion of patients surviving 48 months after therapy initiation. Ninety-six patients (24%) were living at 48 months, 89 of whom had second-look laparotomies. Of the 96 living patients, 53 (55%) were clinically free of disease and 43 (45%) had disease. Combination-agent chemotherapy produced a larger proportion of 48-month survivors than single-agent therapy (P = 0.001); 70% of these survivors were clinically free of disease. Patient characteristics, such as age, International Federation of Gynaecology and Obstetrics (FIGO) stage, histologic grade of tumor, and amount of residual tumor present prior to chemotherapy exerted a strong influence on length of survival. Long-term survival was not totally dependent on a complete response to chemotherapy; in fact, persistent treatment with drug regimens induced bone marrow disorders and death due to toxicity in five patients. The continued fall in survival curves after 48 months suggests that current therapy regimens are not dramatically changing long-term survival rates.
