title: Chemotherapy in advanced ovarian cancer.
abstract: Most patients with epithelial cancer of the ovary are not cured by surgery, since their cancer has spread beyond the ovaries. The majority of these patients are not suitable for postoperative irradiation therapy, since the residual tumors are too large to be effectively treated with irradiation or they have metastasized to areas that cannot be effectively irradiated. Approximately 50% of the patients with advanced ovarian cancer who are treated postoperatively with melphalan will benefit from this chemotherapy. Approximately 40% of the patients who do not respond to chemotherapy with melphalan will benefit from treatment with a combination of actinomycin D, 5-fluorouracil, and cyclophosphamide. A second-look operation after 12 or more cycles of chemotherapy is often helpful in planning future treatment of patients, and it may be curative in a few patients if all the remaining tumor can be excised.
