The main treatment for clear cell carcinoma of the ovary is also surgery. However, the surgical plan should be decided according to the patient’s age, fertility requirements and the condition of both ovaries. If the patient is young and has a unilateral tumor, unilateral ovarian tumor removal or oophorectomy can be performed, preserving the normal ovarian tissue on the same side and the normal ovary on the opposite side. In post-menopausal women, hysterectomy and bilateral adnexal resection or unilateral adnexal resection may be performed. The main goal of surgery for advanced ovarian tumors is to remove all primary foci, remove all metastatic foci as much as possible, and to minimize the residual tumor lesions. After surgery, adjuvant chemotherapy is still needed if necessary.
