Morphological, imaging and surgical aspects in endometrial endometrioid adenocarcinoma.

Endometrioid endometrial adenocarcinomas (EECs) are frequent genital tumors for which the clinical, imaging and histopathological integrated analysis is the basis of differential diagnosis and therapeutic attitude. This research represents a tertiary multicenter study including 58 cases examined histopathologically and immunohistochemically, surgically treated, on a five years period. The main characteristics of the patients in the study group are represented by the average age of 66 years, associated with obesity, hypertension, diabetes, history of infertility, early menopause, nulliparity or long-time oral contraception. The most important clinical sign was the menopausal or postmenopausal vaginal bleeding. The golden standard in the diagnosis of endometrial carcinoma is the dilation and curettage of the uterine cavity, followed by histopathological assessment. The association between transvaginal ultrasonography (TVUS) and endometrial biopsy increases to 100% the diagnostic sensitivity. The use of an antibodies panel that includes CK, ER, PR, vimentin can guide the diagnosis to EEC and the analysis of Ki67, p16, p53 and CEA immunoreactions can be useful both for EEC differential diagnosis and to assess the tumor aggressiveness. The interrelation between the accurate histopathological diagnosis and the adequate surgical staging is the cornerstone of curative therapy in the EEC.
