Abstract：Gynecologic malignant tumor has been the main killer threatening to women′s life. Surgery is a main treatment for most of the gynecology malignant tumor. With the development of minimally invasive surgical techniques ,the laparoscopic surgery in gynecological malignant tumor has been admired and promoted. Learning curve, also called as experience curve, refers to get the rate of knowledge or skills in a certain period of time. It is widely used in the research on the rules of surgical skills acquisition. The main evaluation standard of learning curve includes operation time, intraoperative blood loss, conversion rate, the number of lymph node cleaning, transfer laparotomy and intraoperative and postoperative complications, postoperative hospital stay, and so on. Currently the laparoscopic surgery technology of gynecologic malignant tumor, such as endometrial cancer, cervical cancer, ovarian cancer, vaginal cancer, vulva cancer, has become increasingly mature, but the learning curve of various gynecological malignant tumor laparoscopic surgery reported is not the same. At present ,there is not an international comprehensive description with the evaluation standard,the affecting factors and the existing defects of the learning curve in laparoscopic surgery. This article reviewed and revealed the progress of laparoscopic learning curve in gynecological malignant tumor.
