The main treatment for ovarian anaplastic tumor is firstly surgery. If the patient is in the early stage and has not completed her reproductive function, she can undergo adnexectomy on the diseased side to preserve her reproductive function, and after the surgery, she can be supplemented with chemotherapy because anaplastic tumors are very sensitive to chemotherapy and radiotherapy. For patients with more advanced disease, involving both ovaries or older age, completing the reproductive function, they can undergo subtraction of tumor cells, and can be treated with radiotherapy after surgery, through which this tumor can basically be cured. Since the tumor is very sensitive to radiotherapy and chemotherapy, the recurrence rate after surgery is very rare, and recurrence can be treated by radiotherapy, chemotherapy or second surgery, which can also achieve the goal of cure.
