摘要 目的 通过检测血液循环DNA的基因突变,分析肺癌患者表皮生长因子受体突变的临床特点,探讨其在肺癌靶向治疗中的意义.方法 收集2015年1月至2016年9月浙江省肿瘤医院收治的260例肺癌患者的血浆,采用实时荧光定量 PCR扩增法检测EGFR基因19-21外显子的21种常见突变.结果 260例肺癌血液标本中,共检测到突变98例,突变率37.69%.突变种类最多的前三种分别是L858R、E19del和T790M.亚组分析中,男性和女性的突变率分别是30%和45.66%(P〈0.05).腺癌与鳞癌的突变率分别是34.48%和12%(P〈0.05).腺癌与其他分类的突变率分别是34.48%和52.43%(P〈0.05).24例组织EGFR突变阳性病例中,11例靶向治疗后血EGFR突变转阴,13例血EGFR突变无变化或伴T790M突变.结论 血液EGFR突变检测不仅可为肺癌的靶向治疗用药提供指导,在监测疾病进展和预后分析中也有重要提示作用.
