摘要: 目的:探讨中国乳腺癌患者肿瘤组织中E-钙黏蛋白(E-cadherin)表达与临床病理学指标的相关性。方法:在中国生物医学文献数据库(CBM)、中国知网(CNKI)、PubMed和Cochrane Library等国内外数据库中搜索有关乳腺癌肿瘤组织中E-cadherin蛋白表达与中国乳腺癌患者临床病理学指标的研究文献,以比值比(OR)及95%可信区间(CI)作为E-cadherin蛋白表达、淋巴结转移、组织学分级、临床分期及受体表达(ER/PR/Her-2)的效应量,采用Review Manager 5.0进行统计学分析。结果:共有32篇文献入选,Meta分析结果显示,E-cadherin在乳腺癌组织中的表达与淋巴结转移[OR=0.27,95% CI (0.18,0.41),P<0.05]、组织学分级[OR=0.50,95% CI (0.33,0.77),P<0.05]、临床分期[OR=0.43,95% CI (0.24,0.76);P<0.05]明显相关。结论:E-cadherin的异常表达与乳腺癌进展及转移密切相关,是乳腺癌患者早期诊断和个体化治疗的潜在分子标志物。

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.
