[Non endometroid endometrial cancer guidelines evaluation: A multicentric retrospective study].

Introduction: Non endometrioid endometrial cancer are infrequent and have poor prognosis. The aim of the study was to evaluate non endometrioid endometrial cancer managment by evaluating endometrial cancer guidelines application.
Material and Methods: This multicentric retrospective study enrolled non endometrioid endometrial cancer between January 2009 to December 2019. Analyses adapted at last French guidelines applicated corresponding of year management.
Results: Seventy-four non endometrioid endometrial cancer analysed in 10 centers: 34 carcinosarcoma (45,9 %), 29 serous carcinoma (39,2 %), 9 clear cells carcinoma (12,2 %) and 2 undifferentiated carcinoma (2,7 %). For initial management, endometrial cancer guidelines applicated to 45,9 %. First reason of initial guidelines « non-application » was lack of surgical lymph node stadification (57,1 %). For adjuvant management, endometrial cancer guidelines applicated to 38.7 %. First reason of adjuvant guidelines « non-application » was lack lymph node stadification to complete staging when it previously incompletly operated (67,6 %).
Discussion: Non endometrioid endometrial cancer guidelines applicability is difficult. This explicated by high age and comorbidity when surgical lymph node stadification is necessary. Using new staging technic will allow target management and better select lymph node staging indication.
