ABSTRACT
OBJECTIVE:
To evaluate the correlation of the expression of E-cadherin, alpha-catenin, beta-catenin and the clinicopathological features in endometrial cancer (EC) and atypical complex endometrial hyperplasia (ACEH).METHODS:
Immunohistochemical (IHC) staining of E-cadherin, alpha-catenin, beta-catenin was performed in tissues of 6 ACEHs, 44 endometrioid ECs. We analyzed the correlation of the expression of IHC staining with the prognostic factors according to tumor stage of ACEH and EC, histopathologic grade, and myometrial invasion.RESULTS:
According to tumor stage, reduced E-cadherin expression and abnormal alpha-catenin expression were observed more frequently in advanced stage (reduced E-cadherin ACEH 0%, stage I-II 47.2%, stage III-IV 62.5%, p=0.050; abnormal alpha-catenin ACEH 0%, stage I-II 27.8%, stage III-IV 62.5%, p=0.035). All of the IHC staining showed no correlation with the depth of myometrial invasion but showed correlation with presence of myometrial invasion (reduced E-cadherin invasion(-) 14.3%, invasion(+) 66.7%, p =0.001; abnormal alpha-catenin invasion(-) 7.1%, invasion (+) 46.0%, p=0.010; abnormal beta-catenin invasion(-) 7.1%, invasion(+) 63.0%, p=0.000). According to histological differentiation only abnormal beta-catenin expression shows relationship with histopathologic grade (grade 123.1%, grade 260%, grade 362.5%, p=0.039).CONCLUSION:
Expression of E-cadherin and alpha-catenin showed significantly more reduced expression in EC than in ACEH, and more reduced expression in advanced stage, myometrial invasion and high histopathologic grade. And alpha-catenin showed more frequent abnormal expression in advanced stage, myometrial invasion and beta-catenin showed more frequent in myometrial invasion, high histopathologic grade significantly. These results suggests that the expression of E-cadherin and alpha-catenin, beta-catenin in EC and ACEH could be related to prognosis of the tumor.
