Expression and clinical significance of ghrelin in endometrial hyperplasia and carcinoma of Egyptian patients.

| Abstract |
Endometrial carcinoma ranks the seventh most common malignant tumor worldwide. The distinction between atypical endometrial hyperplasia (AEH) and endometrial carcinoma, especially the well-differentiated grade, is particularly difficult with overlapping distinguishing criteria and small biopsy. Ghrelin is 28 amino acid peptide that is synthesized by gastric mucosa and is expressed in a variety of normal and tumor tissues. In endometrial tissue, it is expressed during the menstrual cycle, involved in the uterine development and cyclic growth. Data regarding role of Ghrelin in endometrial carcinoma are contradictory. In the present study, immunohistochemical expression of Ghrelin was evaluated in 55 endometrioid carcinoma cases, as well as 26 endometrial hyperplasia cases. The relationship between Ghrelin expression and clinicopathologic features of endometrioid carcinoma was studied as well. Ghrelin loss or reduced expression was significantly related to endometrioid carcinoma, especially the well-differentiated type, compared with AEH and EIN (p = 0.000 and 0.006, respectively). Ghrelin loss was also related to poorly differentiated histologic grades of endometrioid carcinoma (p = 0.04). Ghrelin loss is helpful in differentiation between AEH and EIN from endometrioid adenocarcinoma, especially the well-differentiated grade. It could be also related to poor differentiation.
