The main treatment for high-grade plasma ovarian cancer is surgery. The scope of surgery depends on the patient’s age, physical condition, whether or not she has fertility requirements and the stage of ovarian cancer. No matter what stage of ovarian cancer is in, as long as the patient can tolerate surgery, the first choice is surgery. If the cancerous tissue can be removed, the effect of post-operative chemotherapy is better. Because plasmacytoid cystic adenocarcinoma is still sensitive to chemotherapy, but this cancer is more malignant and the recurrence rate is also very high. If the cancer is advanced, it usually recurs even after surgery through radiotherapy in about two years, and the early cure rate is very high.
