Abstract: Laparoscopic surgery is widely used in the treatment of gynecological malignancies，including the radical surgery or staging surgery of early cervical cancer, endometrial cancer and ovarian cancer. Its feasibility and safety of clinical practice in gynecologic malignancies has been approved, and the postoperative followup results indicate that the effectiveness of laparoscopic surgery is similar to open surgery.But the laparoscopic surgery treatment of gynecological malignancies is still in dispute. The research will focus on the affects of pneumoperitoneum to the malignant behavior of tumor cells and the mechanism about implantation metastasis of puncture site in future.
