Abstract:
Objective: To study the expression and clinical significance of Vimentin and E-cadherin in human breast cancer tissues. Methods: : The clinical data of 56 cases of breast cancer patients, who underwent radical mastectomy in Chaohu Hospital Affiliated to Anhui Medical University from January 2014 to January 2016, were retrospectively analyzed. The protein and mRNAexpressions of Vimentin and E-cadherin in breast cancer tissues were detected by immunohistochemistry and qPCR, respectively; and the relationship between the expression of Vimentin and E-cadherin in breast cancer tissues and the clinicopathological characteristics was analyzed. Logistic multivariate regression was used to analyze the independent factors affecting the protein expressions of Vimentin and E-cadherin. Spearman was used to analyze the correlation between Vimentin and E-cadherin. Kaplan-Meier was used to analyze the relationship between protein expressions of Vimentin, E-cadherin and prognosis. ROC curve was used to analyze the diagnostic value of Vimentin and E-cadherin on prognosis. Results: The rates of breast cancer tissues with high positive expression of Vimentin and E-cadherin were 76.79% and 19.64%, respectively.Among them, 47 cases (47/56, 83.93%) of breast cancer tissues showed significantly higher Vimentin mRNA expression than adjacent tissues (P<0.05), and 46 cases (46/56, 82.14%) of breast cancer tissues showed significantly lower Ecadherin mRNA expression than adjacent tissues (P<0.05). Vimentin protein expression was associated with tumor size, lymph node metastasis, vascular invasion, histological grade, clinical stage, molecular typing, Ki67+, ER-, PR- and HER2- expression (P<0.05). And E-cadherin protein expression was associated with lymph node metastasis, vascular invasion, histological grade, clinical stage, molecular typing, Ki67+, ER-, PR- and HER2- expression (P<0.05). Tumor size, lymph node metastasis, vascular invasion, histological grading, clinical staging, molecular typing, Ki67+, ER-, PR- and HER2- expression were all independent factors affecting the expression of Vimentin and E-cadherin (P<0.05). There was a negative correlation between Vimentin and E-cadherin expression (P<0.05). The 3-year survival rate of patients with high expression of Vimentin protein was 67.44%, while that of patients with low expression of E-cadherin protein was 68.89%. Conclusion: The high expression of Vimentin and low expression of E-cadherin in breast cancer tissues may be related to the occurrence, development, invasion and metastasis of breast cancer. It can be used as a reliable indicator of clinical diagnosis and prognosis.
