Detection of EGFR Gene Mutation in Lung Adenocarcinoma by ARMS and Its Clinical Significance / 现代检验医学杂志

ABSTRACT

Objective To investigate the efficacy and clinical significance of amplification refractory mutation system (ARMS)in epidermal growth factor receptor (EGFR) gene mutation in lung adenocarcinoma.Methods Collected 566 specimens of lung adenocarcinomia in pathology from Department of the First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to August 2016.As the research object,which included 34 cases of pleural cell specimens,401 cases of lung biopsy specimens and surgical specimens from 131 patients with ARMS to complete the above specimens EGFR gene mutation detection,analysis of EGFR gene mutations associated with non-small cell lung cancer patients clinical data.Results Among 566 cases of lung cancer specimens,the EGFR mutation rate of 239 cases of patients with smoking had no obvious correlation with age,gender and surgical methods(P＞0.05),but primary lung site was closely related (P＜0.05),and EGFR mutation rate of 327 cases of patients with non smoking had no obvious correlation withage,sex,operation mode and primary lung site (P＞0.05).Conclusion ARMS is an ideal method for the detection of EGFR gene mutation in non-small cell lung cancer.Smoking is a great influence on EGFR mutation rate in both lung tissue,and for right lung tissue is more dramatic.
