Surgical treatment of ovarian cancer is very important, and chemotherapy is equally important, one cannot be without the other. More than 80% of ovarian epithelial cancers are sensitive to chemotherapy, but there are a few patients with primary drug resistance. It is unpredictable whether each patient is sensitive or resistant to chemotherapy, which is called “following the will of God”. “kill a thousand enemies and lose 500,” slowly reduce the enemy, it is impossible to achieve total elimination. Before chemotherapy needs to assess whether it is qualified, that is, to evaluate the function of its own organs, qualified before being able to chemotherapy. During chemotherapy, there will be many side effects of chemotherapy. Generally, doctors will be concerned about the function of the patient’s organs, especially whether the function of the bone marrow is OK, that is, whether the white blood cells have dropped very much. Patients may pay more attention to hair loss, pigmentation, which is relatively unimportant to the bone marrow hematopoietic function, and will recover after stopping chemotherapy. After the chemotherapy is stopped, there is a close follow up, generally there is no other preventive medicine, and patients are advised not to listen to the so-called prescriptions, if there are really effective prescriptions, they should be made public, so that everyone does not get tumor.
