Ovarian cancer is one of the common tumors of female reproductive organs, and its incidence rate ranks third after cervical cancer and uterine body cancer. However, deaths caused by ovarian cancer account for the first place among all kinds of gynecological tumors, posing a serious threat to women's lives. Due to the complex embryonic development, tissue anatomy and endocrine function of the ovaries, the tumors it suffers from may be benign or malignant. Since ovarian cancer has no symptoms in the early clinical stage, it is quite difficult to distinguish its tissue type and benign or malignant. During laparotomy for ovarian cancer, only 30% of the tumors are found to be confined to the ovaries, and most of them have spread to the uterus, bilateral adnexa, greater omentum and pelvic organs. Therefore, ovarian cancer is indeed a big problem in both diagnosis and treatment. Over the years, experts have conducted many discussions on the pathological morphology, clinical occurrence and development rules and treatment plans of ovarian malignant tumors, and accumulated a lot of experience. So far, according to clinical data statistics at home and abroad, its five-year survival rate is only 25% to 30%.
