摘要 目的比较qPCR-HRM法和测序法检测非小细胞肺癌(NSCLC)组织表皮生长因子受体(EGFR)基因突变的差异。方法收集北京协和医院胸外科2010年6月至2011年7月收治的42例非小细胞肺癌患者的石蜡标本,分别用qPCR-HRM法和测序法检测肿瘤组织EGFR基因突变,使用McNemar检验比较其差别。结果 42例标本qPCR-HRM法检测EGFR突变率为33.3%(14/42),测序法为28.6%(13/42),统计学计算未见差异(P=0.5)。结论 qPCR-HRM法检测NSCLC组织EGFR基因突变是一种灵敏、可靠的检测方法,可用于体细胞EGFR突变的检测和测序前突变的筛选。 Objective To compare the difference between qPCR-HRM method and sequence method in detecting EG- FR mutation in NSCLC tissue. Methods EGFR mutation of tumor tissue was detected with qPCR-HRM method and sequence method in the 42 paraffin embedded samples selected from PUMCH thoracic department from June, 2010 to July, 2011. Results EGFR mutation rate was 33.3% (14/42) and 28.6% (13/42) with qPCR-HRM method and sequence method, respectively. There is no significant difference in these 2 results (McNemar Test, P = 0. 5). Conclusion qPCR-HRM method is sensitive and reliable in screening EGFR mutation.
