Abstract: OBJECTIVE: To conduct a Meta-analysis for better understanding the relationship between E-cadherin and clinicopathological indicators in patients with breast cancer. METHODS: All eligible studies reporting associations between E-cadherin expression and clinicopathological features in breast cancer patients were retrieved from CBM, CNKI, PubMed and Cochrane Library databases. Review Manager 5.0 was used to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). RESULTS: A total of 32 studies were included in this Meta-analysis. It was found that the expression level of E-cadherin was significantly correlated with lymph node metastasis[OR=0.27, 95%CI (0.18, 0.41), P<0.05], histological grades[OR=0.50, 95%CI(0.33, 0.77), P<0.05], clinical stage[OR=0.43, 95%CI(0.24, 0.76), P<0.05]. CONCLUSION: Aberrant expression of E-cadherin may play an important role in the progression and metastasis of breast cancer. In addition, aberrent E-cadherin may be a biomarker for early diagnosis and for development of individual therapy.
