Abstract: Ovarian clear cell carcinoma (OCCC) is a special type of ovarian epithelial tumors. Incidence has obvious regional differences, highly morbidity in Asia. Now OCCC has a low incidence in clinical, early onset for low FIGO staging, treatment in time for its main characteristics. Treatment in strict accordance with FIGO staging surgery, and give appropriately full course of chemotherapy, radiation therapy or other treatments after surgery. But patients′ prognosis is still poor. Patients with chemotherapy sensitivity as independent risk factors of prognosis. The 5-year survival rate of patients is associated with OCCC FIGO staging of tumor, preoperative CA125 values more than 150 U/mL or not, the radical remove degree of tumor cells, enough chemotherapy regimens of treatment. The earlier FIGO staging, preoperative CA125 values 150 U/mL or less, clean surgery of tumor resection and postoperative treatment of chemotherapy can improve the 5-year survival rate of patients.
