Cancer of the ovary. ACOG technical bulletin number 141--May 1990 (replaces #73, October 1983)

Surgery followed by appropriate postoperative chemotherapy is the most significant component of treatment of ovarian malignancies. Five-year actuarial (no evidence of disease) survival rates reported in the literature for ovarian epithelial cancer vary: stage I, 60-90%; stage II, 39-67%; stage III, 4-13%; and stage IV, 0-4% (1,18-20). Although more aggressive investigation of adnexal masses, thorough surgical exploration, complete tumor resection, and combination chemotherapy may improve these results, the ability to diagnose ovarian cancer at an earlier stage is required if dramatic improvement in survival is to be seen.
