To the Editor:Synchronous endometrial and ovarian cancer(SEOC)was found in approximately 5%of endometrial cancer(EC)patients and 10%of ovarian cancer patients.[1]In the case of concurrent coexistence of endometrial and ovarian carcinomas,there are two scenarios:two independent primary tumors(IPTs)or ECs with ovarian metastases,which have different prognoses and treatment response.Previous studies have shown that endometrioid tumors classified as IPTs had a better prognosis than those classified as FIGO stage IIIA endometrial cancers(IIIA-ECs)(86%vs.58%5-year survival rates).
