Natural history of epithelial ovarian cancer and its relation to surgical and medical treatment

摘要

cqvip:Epithelial ovarian cancer(EOC) represents approximately 90% of primary malignant ovarian tumors, the sixth most common cancer in women and the second most common gynecologic cancer. Approximately 80%-85% of all ovarian carcinomas in Western society are serous and up to 95% of patients are in advanced stages(FIGO stage Ⅲ-Ⅳ) at diagnosis. Treatment of ovarian cancer is mainly based on three key approaches: surgical removal of neoplasia; chemotherapy to kill cancer cells; direct chemotherapy on peritoneal surfaces. The application of hyperthermic chemotherapy to the peritoneal cavity(HIPEC) after radical surgery may also be an attractive option. We analyzed the natural history of EOC in the literature and identified various time-points where sensitivity to chemotherapy, freedom from disease and overall survival are different. We propose eight time-points in EOC history with homogeneous oncological fi ndings. The effectiveness of HIPEC in EOC treatment should be evaluated based on these eight time-points and we believe that retrospective and prospective studies of HIPEC should be evaluated according to these time-points.
