EGFR及KRAS基因突变与非小细胞肺癌临床病理特征的关系
Relation of EGFR and KRAS gene mutations with its pathological characteristics in non-small cell lung cancer
摘要
Abstract
Purpose To investigate the relation of EGFR and KRAS gene mutations with the pathological characteristics in non-small cell lung cancer (NSCLC).Methods The EGFR and KRAS gene mutations were detected and analyzed in 64 patients with NSCLC by capillary electrophoresis and fluorescent probe method.Results In 64 cases,the EGFR gene mutations were detected in 27 patients (42.2％);the KRAS gene mutations in 8 patients (12.5％).The EGFR and KRAS mutations synchronized in 4 patients (6.25％).The mutations rate of EGFR was related to gender,histology type and smoking condition (P ＜ 0.05).There was no association between mutation of EGFR gene with the age,differentiation,lymph node metastasis and TNM stages (P ＞ 0.05).The mutations rate of KRAS gene was higher in adenocarcinoma patients than that in squamous carcinoma (P ＜ 0.01).There was no relationship between mutation of KRAS gene with the gender,age,smoking condition,differentiation,lymph node metastasis and TNM stages (P ＞ 0.05).Conclusion In NSCLC,EGFR gene mutations rate is higher than KRAS gene mutation.The mutation rate of EGFR gene is higher in female,adenocarcinoma and never smokers;the mutations rate of KRAS mutations is higher in patients with adenocarcinoma.The mutations in EGFR and KRAS can exist at the same time.关键词
