Borderline ovarian tumor (BoT) is a low-grade potentially malignant ovarian tumor, accounting for 10% to 15% of ovarian epithelial tumors. BOT occurs predominantly in women of childbearing age, of which 80% of patients are in BOTⅠ～Ⅱstage. Clinically, BOT is characterized by histological characteristics of malignant epithelial ovarian cancer, but lacks interstitial infiltration, is not sensitive to chemotherapy, and is prone to late relapse, but most of the relapse is still BOT.

　　Can a borderline tumor be cured? How should borderline ovarian tumors be treated? Can the patient benefit the most? Let’s first look at how the borderline ovarian tumors are found. Most borderline ovarian tumors have no symptoms. They are only found during gynecological examination and ultrasound examination. Of course, some borderline tumors will have abdominal distension and compression symptoms as the tumor grows. . The diagnosis of borderline ovarian tumors depends on pathology, but the accuracy rate of experienced B-ultrasound doctors to predict borderline ovarian tumors before surgery is also quite high.
　　The chance of cyst rupture in laparoscopic surgery is significantly increased, but the probability of postoperative tumor recurrence has not increased, the 5-year survival rate has not changed, and there is no difference in prognosis. Therefore, the current borderline ovarian tumor is not a restricted area for minimally invasive surgery. In gynecology, ovarian borderline papillary serous cystadenoma is more common. If the tumor size is small and the patient is young, the affected ovary can be removed. Short-term follow-up follow-up if the tumor body (12X10X5CM is relatively large) In middle-aged or elderly patients, the affected side of the ovary can be removed, and some hospitals do lymph node dissection on the affected side. The specific surgical method should be determined according to the specific physical condition of the patient, and it is not generalized.
