Problematic areas in the reporting of endometrial carcinomas in hysterectomy specimens

[Endometrial carcinoma: An histopathological and histoprognotic study about 62 patients in a center in the Tunisian north]

Endometrial cancer is the most prevalent genital tract cancer in occident and the third most common cancer among women in Tunisia. It is dominated by carcinoma. The identification of prognostic factors allows a better understanding of its outcome and guides its therapeutic approach. We propose to describe the clinicopathological features and identify the histoprognostic factors of this cancer. It is a retrospective analysis of a series of 62 total hysterectomy specimens with bilateral salpingo-oophorectomy from women with primary carcinoma of the endometrium, colligated in Anatomy Laboratory and Pathology Salah Azaiz Institute of Tunis over a period of 5 years, from January 2003 to December 2007. The median age was 60 years. At the time of diagnosis, 25% of patients were nulliparous and 86% were menopaused. The endometrioid adenocarcinoma was the most common, accounting for 84% of cases (5% of them were grade 3). A myometrial invasion superior or equal to 50% was observed in 40% of cases. 42% of cases were classified as stage IA, 14% in stage IB, 16% in stage II, 18% stage III and 10% in stage IV. 22% of patients had nodal involvement. Overall survival at 5 years was 81%. In multivariate analysis, stage IV, nodal involvement and brachytherapy have influenced this rate. Event-free survival at 5 years was 71%. It was directly related to stage and nodal involvement. Stage, histological type, tumor grade, invasion of more than half of the myometrium and lymph node involvement were the most important adverse prognostic factors, dictating an appropriate management of these tumors.
