Abstract: There is no agreement about the range and model of surgical treatment in endometrial carcinoma，especially for the necessity of systematic pelvic and para-aortic lymphadenectomy. The sentinel lymph node selectively excision can be preceded in low risk early-stage endometrial carcinoma. But in high risk group，retroperitoneal lymph node dissection can not replace the systematic and complete pelvic and para-aortic lymphadenectomy which does not increase the risk for major organ damage，second surgery and severe intestinal obstruction. Systematic and complete pelvic and para-aortic lymphadenectomy can improve the survival and prognosis.
