Their study showed that the mean rank of E-cadherin histoscore in AH was significantly higher than the mean rank in endometrial adenocarcinomas. This shows that the expression of E-cadherin is higher in endometrial adenocarcinomas than in AH of the endometrium [6]. The study also revealed that there is no significant correlation between the stage of the tumor and E-cadherin expression [8]. This evidence concerns the gene CDH1 and endometrium adenocarcinoma.
