摘  要:目的检测食管鳞癌组织中人表皮生长因子受体2(HER2)/neu基因扩增和蛋白表达,并探讨其与食管鳞癌临床病理特征的关系。方法采用荧光原位杂交(FISH)和免疫组织化学(IHC)方法检测120例食管鳞癌组织中HER2/neu基因扩增及蛋白表达水平。结果FISH结果示食管鳞癌组织中HER2/neu基因扩增率为4.17%(5/120),IHC示HER2蛋白过表达(+++)率为3.33%(4/120),基因扩增与蛋白表达明显相关(P〈0.01);HER2/neu基因扩增和蛋白过表达与食管鳞癌患者的临床病理特征均无相关(P〉0.05)。结论食管鳞癌组织HER2/neu基因扩增及蛋白表达率均较低,其在食管鳞癌中的意义有待进一步的研究。Objective To investigate human epidermalgrowth factor receptor-2 ( HER2)/neu gene amplification and protein expression in esophageal squamous cell carcinoma (ESCC) and to explore their clinicopathological correlations. Methods The HER2/neu gene status and protein expression in 120 cases of ESCC were evaluated by using fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC). Results HER2/neu gene amplification and HER2 protein overexpression ( +++ ) were found in 5 (4. 17% ) and 4 (3.33%) cases of ESCC respectively. HER2 overexpression was associated significantly with HER2/neu gene amplification. There was no correlation between the HER2/neu gene amplification or overexpression of HER2 protein and the ESCC patients' clinicopathological features. Conclusion The HER2/neu gene amplification rate and its protein overexpression rate in ESCC were low, and the role HER2/neu gene plays in ESCC still need further studies.
