Low-grade plasma ovarian cancer 3a can usually be treated with surgical treatment, radiotherapy and chemotherapy. If the tumor can be surgically resected and the patient can tolerate the surgery, surgical resection can be preferred, followed by chemotherapy and other means of treatment, such as cisplatin, paclitaxel, etc. If the tumor is not suitable for surgical resection due to metastasis and other reasons, tumor subtractive surgery can be chosen to reduce the lesion, and at the same time cooperate with chemotherapy and other means of treatment, so as to prolong the patient’s survival time. The prognosis of low-grade plasmacytoid ovarian cancer is generally better than that of common ovarian cancer. After receiving chemotherapy, the white blood cells of patients will decrease rapidly and their immunity will be lowered, so they should pay attention to self-protection in order to avoid infection. After diagnosed with low-grade plasmacytoid ovarian cancer, patients should undergo regular review to avoid aggravation and recurrence of the disease.
