摘要
目的分析初治非小细胞肺癌(non-small cell lung cancer,NSCLC)患者肺原发灶EGFR(epidermal growth factor receptor,EGFR)基因突变状态与临床病理特征的相关性,为临床EGFR-TKIs(tyrosine kinase inhibitors,TKIs)用药提供依据。方法收集第三军医大学附属大坪医院应用增殖阻遏突变系统(amplification refractory mutation system,ARMs)进行EGFR突变分析253例初治非小细胞肺癌患者的性别、年龄、吸烟史、KPS(Karnofsky performance status,KPS)评分、组织病理类型、TNM临床分期以及伴有脑转移患者的脑转移灶数量、确诊肺癌至诊断脑转移时间(brain metastasis time from diagnosis of lung cancer,BMT)和颅外转移状况等临床病理资料,应用χ2检验分析EGFR突变状态与各临床病理特征的关系。结果 253例初治NSCLC患者,EGFR基因敏感型突变率42.3%(107/253),其中EGFR基因第19、21外显子突变比例分别为70.1%(75/107)、39.1%(32/107),而EGFR基因20外显子TKIs耐药型突变率0.8%(2/253)。女性、无吸烟史、腺癌的肺原发灶EGFR基因敏感型突变率明显高于男性、有吸烟史、非腺癌患者,分别为70.2%(66/94)vs 25.8%(41/61)、60.9%(81/133)vs 18.1%(19/105)和50.0%(103/206)vs 8.5%(4/47),两者有显著性差异(P<0.05)。结论初治NSCLC患者肺原发灶存在较高(42.3%)EGFR基因敏感型突变,其中女性、腺癌、无吸烟史NSCLC患者EGFR基因敏感突变显著多见。
