Whether chemotherapy is needed for endometrial cancer depends on its clinical stage. If it is advanced endometrial cancer, such as stage IV, chemotherapy is necessary for these patients. Recurrent endometrial cancer also requires chemotherapy. In the case of early-stage endometrial cancer, surgery can be used. The purpose of the surgery is to stage the pathology of the cancer to determine the extent of endometrial cancer infiltration. After the surgery, it will be assessed whether chemotherapy is needed. Therefore, whether chemotherapy is needed for endometrial cancer depends on the surgical staging. Some endometrial cancers may require not only chemotherapy but also radiotherapy treatment.
