BACKGROUND: Although lower uterine segment (LUS) is regarded as an anatomically defined part that possess some histological differences, it is involvement by carcinoma have not been included in the criteria for definition in the staging system for endometrial carcinoma and there are few conflicting data focused on the effect of LUS involvement as a prognostic factor in endometrial cancer.

AIM: To find the association between LUS involvement in corpus located endometrioid carcinoma with the grading and staging system established by the international federation of gynecology and obstetrics (FIGO).

METHODS: This was a retrospective study involving data collected from achieves of histopathology departments of teaching laboratories within successive 4 years period in Medical City complex at Bagdad. Pathological analysis of 70 hysterectomy specimens of corpus located endometriod adenocarcinoma was done, histological sections from each case of endometrioid adenocarcinoma carcinoma were microscopically reviewed for appropriate grading and staging, in addition, meticulous search was applied for histological finding consistent with LUS involvement. The statistical comparison between the results was done using either independent sample t-test (for continuous data; mean ± SD) or Chi-square test at a significant p < 0.05.

RESULTS: The study enrolled 70 histological samples of endometrioid adenocarcinoma, the majority of the samples were of low grade and stage at presentation. Of total sample, 46 (65.71%) showed LUS involvement by tumor cells. There was a significant statistical relationship between LUS involvement and FIGO stage while a non-significant statistical association with FIGO grade was found.

CONCLUSION: LUS involvement by corpus located endometrioid adenocarcinoma is associated with an advanced FIGO stage at presentation while non-significant relationship was found between patient age and tumor grade.
