摘要: 目的 探讨MT2-MMP在肺腺癌患者组织中的表达情况及其临床意义。方法 收集40例病理TNM分期Ⅱ期的肺腺癌组织标本,其癌旁正常组织为对照组,进行HE染色,免疫组织化学方法检测MT2-MMP的表达进行半定量分析;应用卡方检验分析MT2-MMP表达与临床病理特征的关系;结合TCGA肺腺癌数据分析MT2-MMP在肺腺癌中的表达情况。结果 肺腺癌组织呈现明显的肿瘤无序增殖病理特征;MT2-MMP在肺腺癌中表达高于癌旁正常组织,差异具有统计学意义(P<0.001);肺腺癌组织中的MT2-MMP的表达水平与患者的肿瘤大小有关(P<0.01),而与性别、年龄、是否有淋巴转移无明显相关(P>0.05);TCGA大数据分析结果显示肺腺癌Ⅱ期及其他各期MT2-MMP的表达均显著高于正常组织,差异具有统计学意义(P<0.01)。结论 MT2-MMP在Ⅱ期肺腺癌组织中呈高表达,可能参与肺腺癌早期的恶性进展,对肺腺癌的早期诊断具有潜在价值。

Abstract: Objective The aim of this study was to investigate the expression of MT2-MMP in lung adenocarcinoma and its clinical significance.Methods A total of 40 cases of lung adenocarcinoma with pathological TNM stage Ⅱ were collected,and the adjacent normal tissues were used as controls.Immunohistochemistry was used to detect the expression of MT2-MMP for semi-quantitative analysis.Chi-square test was used to analyze the relationship between MT2-MMP expression and clinicopathological characteristics.Combined with TCGA lung adenocarcinoma data,the expression of MT2-MMP was analyzed in lung adenocarcinoma.Results Lung adenocarcinoma tissues showed obvious pathological characteristics of disordered tumor proliferation.The expression of MT2-MMP in lung adenocarcinoma tissues was higher than that in adjacent normal tissues,and the difference was statistically significant(P<0.001).The level of MT2-MMP in lung adenocarcinoma tissues was related to the tumor size of patients(P<0.01),but was not significantly correlated with gender,age,presence or absence of lymphatic metastasis(P>0.05).The TCGA data analysis results showed that the expression of MT2-MMP at the stage II of lung adenocarcinoma and other stages was significantly higher than that in normal tissues,and the difference was statistically significant(P<0.01).Conclusion MT2-MMP is highly expressed at the stage II of lung adenocarcinoma,which may be involved in the early malignant progression of lung adenocarcinoma,and has potential value for the early diagnosis of lung adenocarcinoma.
