Such patients do not have surgical indication, so they can be treated with radiotherapy, chemotherapy and other treatments, which can control the condition and prolong the survival period. However, there are also some patients who have no metastasis to other parts of the body despite the occurrence of abdominal metastasis in advanced stage of ovarian cancer, and they are relatively in good condition, and may be treated with surgery. Ascites in advanced stage of ovarian cancer must cooperate with doctor to do detailed examination and take treatment according to doctor’s examination results and suggestions.
