Brain metastasis of ovarian cancer can have a survival period of 1-2 years if actively treated, but only a few months if treatment is abandoned. Brain metastasis of ovarian cancer indicates that the patient has already entered the advanced stage, if the patient can be treated actively with radiotherapy, chemotherapy and targeted therapy, and if the effect is good, the survival period can be prolonged by 1-2 years; however, if the effect of treatment is not satisfactory or if the patient gives up the treatment, the patient will usually die within a few months due to organ failure. Brain metastasis of ovarian cancer is still mainly treated with comprehensive treatment, and at the same time, diuretic, pain relief and other treatments are taken according to the symptoms, which are mainly to prolong the survival time and improve the quality of life, but it is still difficult to be cured completely. It is suggested that patients with brain metastasis of ovarian cancer should go to regular hospitals in time, keep a good mindset, and actively cooperate with the treatment in order to prolong the survival period.
