2、R第l9、21号外显子进行检测。结果162例非小细胞肺癌患者发生EGFR突变阳性63例,突变阳性率为38.89%。腺癌、女性、非吸烟者、有肺癌及其他恶性肿瘤家族史的非小细胞肺癌患者EGFR突变率明显升高.差异有统计学意义(P<0.05),但与患者年龄,肿瘤分级、分期、大小、是否转移无关(P>0.05)。非小细胞肺癌发生EGFR突变阳性使用EGFRTKIs靶向治疗患者的中位生存期明显长于未治疗及其他药物化疗患者,差异有统计学意义(P3、肿瘤家族史患者更具有临床意义。【关键词】癌,非小细胞肺;基因,erbB一1;受体,表皮生长因子;基因;突变doi:10.3969/j.issn.1009.5519.2014.11.007文献标识码:A文章编号:1009.5519(2014)11-161503ClinicalsignificanceofEGFRgenemutationsinnon—smallcellungcancerLinFang,YangMin~in,TangWanyan,.~angYoufan(DepartmentofRespiratory,th4、eSecondAfiliatedHospitalofChongqingMedicalUnwe~ity,Chongqing400010,China)【Abstract】ObjecfiveToinvestigatetheassociationsbetweenthemutationsofcxons19and21ofepidermalgrowthfac—torreceptor(EGFR)genesandclinic叩athologicalcharacteristics,andfamilyhistoryinnon—small5、celllungcancer(NSCLC),andfurtherexplorethecurativeeffectoftargetedtherapyinpatientswithpositivemutationsbyepidermalgrowthfactorreceptortyrosinekinaseinhibit0rs(EGFR.TKIs).MethodsAmplificationRefractoryMutationSystem-PolymeraseChainReaction(ARMS-PCR)wasappliedt6、odetectthemutationsofexons19and21ofEGFR.ResultsTheresultsshowedthat63patientswerewithEGFRmuta—tionsin162NSCLCpatients,andthepositiverateofmulationwas38.89%.Furthermore,themutationratewasobviouslyhigherinNSCLCpatientswithadenocarcinoma,woman,non—smoking,lungcan7、cerorfamilyhistoryofmalignancy,andthediferencehadstatisticalsignificance(P<0.05).However,themutationratehadnosignificantcorrelationwithpatientsage,tumorgrade,stage,size,metastasisornot(P>O.05).ThemediansurvivaltimeoftheNSCLCpafien~,whoweretreatedwithEGFR-TKIs,8、wasprolongedsignificantlyinpatientswithpositivemutationwithstatisticallysignificantdiference(P
