2、,外显子18、19、20和21的突变率分别为0.93%(2/214)、22.0%(47/214)、2.3%(5/214)和20.6%(44/214)。另有2例19和21外显子双重突变。EGFR基因在肺腺癌组织中的总突变率为50.3%(93/185)明显高于肺鳞状细胞癌17.2%(5/29)(P=0.001)。EGFR基因在女性患者中的突变率57.0%(57/100)高于男性36.O%(41/114)(P=0.002),EGFR基因在NSCLC淋巴结转移患者中的突变率(66.7%)显著高于无淋巴结转移患者(39.5%)(P3、),但EGFR基因突变率与肺癌患者的年龄、肿瘤分级和,临床分期均无显著性差异(P>0.05)。结论:中国肺癌尤其是肺腺癌患者存在EGFR基因的较高突变率,EGFR外显子19、21突变结合肺癌的临床病理特征有望成为评估TKI治疗非小细胞肺癌疗效的分子标志。关键词非小细胞肺癌表皮生长因子突变doi:10.3969/j.issn.1000-8179.20140495ClinicalsignificanceofEGFRmutationsinnon—smallcelllungcancerJunZHENG,GuiyuanXIE,JiaoLI,4、JiadiLUO,QiuyuanWEN,SongqingFANCorrespondenceto:SongqingFAN;E-mail:songqingfan2000@yahoo.cornDepartmentofPathology,TheSecondXiangyaHospitalofCentralSouthUniversity,Changsha410011,China;DepartmentofBiochemistry,ChangzhiMedicalCollege,Changzhi,Shanxi,046000,China;Depart5、mentofOncology,theSecondXiangYaHos—pitalofCentralSouthUniversity,Changsha,410011,ChinaThisworkwassupposedbytheNationalNaturalScienceFoundationofChina(No.81272566)Abstract0bjeetive:Toinvestigatethemutationsoftheepidermalgrowthfactorreceptor(EGFR)geneanditsclinicalsigni6、fi—canceinnon-smallcelllungcancerSCLC).Methods:TheEGFRgenemutationsofexons18to21inNSCLCweredetectedbyus—ingtheADx-ARMS@detectionkitmethod.Results:Thetotalmutationpercentageinexons18to21oftheEGFRgenewas45.8%f98/214)inNSCLC.Thesemutationspredominantlyoccurinexons19and217、.EGFRgenemutationpercentageswerefoundinexons18(0.93%,2/214),19(22.0%,47/214),20(2_3%,5/214),andexon21(20.6%,44/214)intheNSCLC.TwoNSCLCcaseswereidentifiedtohavedoubleEGFRgenemutationsofexons19and21.EGFRgenemutationsweremorefrequentlyobservedwithadenocarcinomahistology(8、50.3%,93/185)thanwithsquamouscellcarcinoma(17.2%,5/29)(P=O.OO1).EGFRgenemutationsoccurmorefrequentlyinNSCLCcasesinwomenthani
