【 摘 要】 目的 探讨非小细胞肺癌( NSCLC) 患者 EGFR 基因突变状态及其与临床病理特征的关系。 方法 收集
2015 年 1 月至 2017 年 12 月成都市第三人民医院确诊的 NSCLC 病理标本 203 例,其中石蜡切片 113 例,新鲜组织 41 例,胸腔 积液 49 例。 采用突变扩增阻滞系统( ARMS) ⁃Taqman 探针法检测 EGFR 基因外显子突变状态,分析其与临床病理特征的关 系。 采用 Logistic 回归分析影响 NSCLC 患者发生 EGFR 突变的因素。 结果 203 例 NSCLC 患者中,有 97 例检测到 EGFR 突 变(47������ 8%) ,其中 TKIs 药物敏感性突变 82 例( L858R 突变 44 例,19⁃del 突变 35 例,G719C / G719S 突变 1 例,L861Q / S768I 突 变 2 例) ,TKIs 耐药性突变 7 例,另有 8 例为多位点突变。 多位点突变中携带 T790M 突变率高(87������ 5%) ,以男性、Ⅳ期、腺癌患 者为主。 EGFR 突变主要发生在女性、无吸烟史、腺癌患者;19⁃del 和 L858R 突变在女性中占的比例更高,分别为 57������ 1% 和 54������ 5%,而其他突变类型在男性中占的比例更高(72������ 2%) 。 Logistic 回归分析显示,无吸烟史患者的 EGFR 突变率更高( HR = 4������ 146,95%CI:1������ 802 ~ 9������ 536) 。 结论 四川地区 NSCLC 患者 EGFR 基因突变以 L858R 和 19⁃del 突变为主,女性、无吸烟史、肺 腺癌患者更易发生 EGFR 突变,吸烟状态是预测 EGFR 突变的独立因素。
tor receptor ( EGFR) mutation subtype in non⁃small cell lung cancer ( NSCLC) . Methods From January 2015 to December 2017, a total of 203 pathological samples were enrolled, including paraffin section 113 cases, fresh resected tissue 41 cases and pleural effusion 49 cases. Their EGFR mutation was detected with ARMS⁃Taqman. The relationships between EGFR and clinicopathological features were analyzed. Logistic regression model was used to analyze the factors influencing EGFR mutation. Results Among these samples, 97 had EGFR mutation ( 47������ 8%) , with 82 were of TKIs sensitive mutation ( including 44 L858R mutation, 35 19⁃del mutation, 1 G719C / G719S mutation and 2 L861Q / S768I mutation) , 7 were of TKIs resistant mutation, and 8 were of multi⁃location mutation. Multi⁃location mutation was almost T790M mutation (87������ 5%) , mainly in male, stage Ⅳ and and adenocarcinoma patients. EGFR mu⁃ tations occurred more frequently in female, non⁃smokers and adenocarcinoma patients. 19⁃del and L858R mutations occurred predomi⁃ nantly in female, accounting for 57������ 1% and 54������ 5%,respectively. Other mutation types occurred predominantly in male (72������ 2%) . EG⁃ FR mutation rate was higher in patients without smoking history with binary Logistic regression analysis( HR = 4������ 146,95% CI:1������ 802⁃ 9������ 536) . Conclusion The EGFR gene mutation in NSCLC patients in Sichuan province were mainly found in L858R and 19⁃del. EG⁃ FR mutation was more frequently occurred in female, non⁃smoker and lung adenocarcinoma patients. Smoking status was independent
