Histopathological Prognostic Factors for Endometrial Carcinoma.

Abstract

ABSTRACT: The purpose of our study was to determine the incidence and the relationship between prognostic factors (age at diagnosis, pTNM stage, histological grade, lymph vascular and myometrium invasion) in patients with endometrial carcinoma. We evaluated in terms of diagnosis 50 cases of endometrial carcinomas that were hospitalized during 2011-2014 in the Obstetrics, Gynecology and Surgery clinics of the Emergency County Hospital Craiova. The procedure consisted in fixation in 10% buffered formalin, followed by processing with usual technique of paraffin embedding and finally staining in hematoxylin and eosin. The histological analysis of the 50 endometrial carcinomas revealed well-differentiated carcinomas (G1) in 24 cases (48%), moderately differentiated carcinomas (G2) in 17 cases (34%) and poorly differentiated carcinomas (G3) in further 9 cases (18%).The myometrium invasion was present in the internal half of the myometrium in 12 internal cases (24%) and in the external half of myometrium in further 36 cases (72%). In 2 cases (4%) the myometrium invasion was absent. We achieved significant association between histological grade and invasion of myometrium, also between histological grade and lymphovascular invasion, as well as tumor stage and myometrium invasion. We are also able to report significant association between lymphovascular invasion and tumor stage or tumor stage and presence of lymph nodes. The results of this study emphasize the importance of pathological parameters as prognostic factors in endometrial carcinoma.
