摘要:目的  探討HER2、EGFR、VEGFR在胃印戒细胞癌中的表达及其临床意义。方法  选取我院2013年 4月~2018年3月胃印戒细胞癌组织55例,检测中的人类表皮生长因子受体2(HER2)、表皮生长因子受体(EGFR)和血管内皮生长因子(VEGF-R)表达并分析其与胃印戒细胞癌临床特征的关系。结果  胃印戒细胞癌组织中HER2、EGFR、VEGFR的表达率分别为43.64%(24/55)、38.18%(21/55)和38.18%(21/55)。相关性分析显示,HER2、EGFR、VEGFR表达与浸润深度、淋巴结转移及TNM分期有关(P<0.05),与性别、年龄无关(P>0.05);HER2、EGFR、VEGFR三者存在共表达现象,表达强度呈正相关。结论  胃印戒细胞癌组织中HER2、EGFR、VEGFR表达水平与胃印戒细胞癌组织恶性程度密切相关,通过对HER2、EGFR、VEGFR三者表达水平的检测可能有助于降低胃印戒细胞癌术前的误诊率、为靶向HER2、EGFR、VEGFR生物治疗制剂在胃印戒细胞癌生物治疗中的应用及联合应用提供了一定的理论依据。

Abstract:Objective  To investigate the expression of HER2, EGFR and VEGFR in gastric signet ring cell carcinoma and its clinical significance. Methods  55 cases of gastric signet ring cell carcinoma tissues from April 2013 to March 2018 in our hospital were selected. The expressions of human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF-R) in the test were analyzed and their relationship with clinical features of gastric signet ring cell carcinoma was analyzed. Results  The expression rates of HER2, EGFR, and VEGFR in gastric signet ring cell carcinoma tissues were 43.64% (24/55), 38.18% (21/55), and 38.18% (21/55). Correlation analysis showed that the expressions of HER2, EGFR, and VEGFR were related to the depth of invasion, lymph node metastasis, and TNM stage (P<0.05), and were not related to gender and age (P>0.05);co-expression of HER2, EGFR, and VEGFR existed, and the expression intensity was positively correlated.Conclusion  The expression levels of HER2, EGFR, and VEGFR in gastric signet ring cell carcinoma tissues are closely related to the malignant degree of gastric signet ring cell carcinoma tissues. Detection of the expression levels of HER2, EGFR, and VEGFR may help reduce gastric signet ring cell carcinoma. The preoperative misdiagnosis rate provided a certain theoretical basis for the application and combination of targeted HER2, EGFR, and VEGFR biotherapeutics in the biological treatment of signet ring cell carcinoma.

综上所述,HER2、EGFR、VEGFR三者在胃印戒细胞癌中均呈现较高表达,且均参与了胃印戒细胞癌发生发展的过程。因此,通过对三种因子行免疫组化检测不仅在术前诊断上可进一步降低胃印戒细胞癌的误诊率,同时在胃印戒细胞癌患者的多种靶向药物联合治疗获得更好预后上提供理论基础。
