摘要: 目的 了解深圳地区非小细胞肺癌(non-small cell lung cancer,NSCLC)表皮生长因子受体(epidermal growth factor receptor,EGFR)基因突变情况,为NSCLC患者药物靶向治疗提供科学依据。方法 收集2013年3月~2015年11月深圳地区3家三级区属医院的103例NSCLC肺癌组织,分别提取DNA,采用突变特异性扩增系统(ARMS)扩增检测EGFR基因外显子18、19、20及2l的突变情况,并统计分析EGFR基因突变率。结果 103例NSCLC患者中EGFR基因总突变率为38.8%(40/103),其中第18、19、20及21外显子突变分别占总突变的2.5%(1/40)、35.0%(14/40)、5.0%(2/40)及57.5%(23/40);腺癌患者EGFR基因突变率为48.7%(37/76),高于非腺癌患者的11.1%(3/27),差异有统计学意义(χ2=25.617,P<0.01);不吸烟的NSCLC患者EGFR基因突变率为56.1%(32/57),明显高于吸烟患者的17.4%(8/46),差异有统计意义(χ2=20.195,P<0.01);女性患者突变率为52.4%(22/42),高于男性患者的29.5%(18/61),差异有统计意义(χ2=5.127,P<0.05);≤56岁的NSCLC患者EGFR基因突变率为39.5%(17/43),>56岁的患者为38.3%(23/60),差异无统计学意义(χ2=0.618,P>0.05)。结论 深圳地区NSCLC患者EGFR基因突变主要以21外显子为主,其次为19外显子;腺癌、女性及不吸烟NSCLC患者EGFR基因突变率较高,可接受EGFR-TKIs治疗。

Abstract: Objective To understand non-small cell lung cancer(NSCLC)epidermal growth factor receptor (EGFR) mutations in Shenzhen,and to provide a basis for target therapy of NSCLC patients. Methods collected from March 2013 to November 2015 in shenzhen area three level 3 district hospital,One hundred and three cases of NSCLC cancer tissues were collected in 3 hospitals from 2013 to 2015,and DNA was extracted followed by detections of EGFR gene mutation in exon 18,19,20 and 2l using mutations specific amplification system (ARMS) amplification. Results All of 103 cases of NSCLC showed an EGFR gene mutation rate of 38.8% (40/103),among them 18,19,20 and 21 exon mutations rates were 2.5%(1/40),35.0%(14/40),5.0%(2/40),and 57.5%(23/40),respectively. EGFR mutation rate was 48.7% (37/76)in patients with adenocarcinoma,higher than 11.1%(3/27)in the patients with non-adenocarcinoma.(χ2=25.617,P<0.01). EGFR mutation rate in NSCLC patients of nonsmookers was 56.1% (32/57),significantly higher than the smooker patients( 17.4%,8/46) (χ2=20.195,P<0.01). The mutation rate in female patients was 52.4%(22/42),higher than that of the male (29.5%,18/61)(χ2=5.127,P<0.05). The patients below 56 years exhibited an EGFR mutation rate of 39.5% (17/43),compared to those over 56 years (38.3%,23/60)(χ2=0.618,P>0.618).Conclusion EGFR mutations in NSCLC patients are mainly composed of exon 21,followed by exon19. Adenocarcinoma,femal,and nonsmoker patients seem to be the risk factors of EGFR gene mutation.
