摘　　要：目的分析非小细胞肺癌(NSCLC)患者肝细胞生长因子受体(c-Met)、表皮生长因子受体(EGFR)和间变性淋巴癌激酶(ALK)基因异常与临床病理特征的关系。方法回顾性分析2021年1—12月新钢中心医院收治的152例NSCLC患者的临床资料,取患者组织标本,采用荧光原位杂交技术检测c-Met基因扩增情况,采用聚合酶链扩增反应及直接测序法检测EGFR基因突变情况,采用实时荧光定量PCR检测ALK基因重排情况。分析c-Met基因扩增、EGFR基因突变和ALK基因重排与患者临床病理特征的关系。结果152例NSCLC患者中,c-Met基因扩增7例,阳性率为4.61%;EGFR基因突变48例,突变率为31.58%;ALK基因重排8例,重排率为5.26%。c-Met基因扩增阳性与阴性患者、ALK基因重排与无重排患者性别、年龄、临床分期、吸烟史、肿瘤位置、病理类型比较差异无统计学意义。EGFR基因突变与无突变患者性别、年龄、病理类型比较差异有统计学意义(P<0.05),其中EGFR基因突变患者以女性、年龄<70岁、腺癌占比较高。结论c-Met基因扩增及ALK基因重排与患者临床病理特征无关,而EGFR基因突变与患者性别、年龄及病理类型密切相关。Objective To analyze the relationship between gene abnormalities of hepatocyte growth factor receptor(c-Met),epidermal growth factor receptor(EGFR)and anaplastic lymphoma kinase(ALK)gene abnormalities and clinicopathological features in patients with non-small cell lung cancer(NSCLC).Methods The clinical data of 152 patients with NSCLC admitted to Xingang Central Hospital from January to December 2021 were retrospectively analyzed,tissue specimens were taken from patients,and c-Met gene amplification was detected by fluorescence in situ hybridization,EGFR gene mutation was detected by polymerase chain amplification reaction and direct sequencing,and ALK gene rearrangement was detected by real-time fluorescence quantitative PCR.The relationship between c-Met gene amplification,EGFR gene mutation and ALK gene rearrangement and clinicopathological features of patients was analyzed.Results Among 152 patients with NSCLC,there were 7 cases of c-Met gene amplification,the positive rate was 4.61%;48 cases of EGFR gene mutation,the mutation rate was 31.58%;8 cases of ALK gene rearrangement,the rearrangement rate was 5.26%.There were no statistical difference in gender,age,clinical stage,smoking history,tumor location,pathological type between c-Met gene amplification positive and negative patients,and between ALK rearrangement and non-rearrangement patients.There were significant differences in gender,age and pathological types between EGFR gene mutation and non-mutation patients(P<0.05),and the proportion of female,age<70 years old and adenocarcinoma was higher in patients with EGFR gene mutation.Conclusion c-Met gene amplification and ALK gene rearrangement were not associated with clinicopathological features of patients,while EGFR gene mutation was closely associated with patient gender,age and pathological type of patients.
