湖北地区非小细胞肺癌EGFR 基因突变及其意义的研究
Detection of Epidermal Growth Factor Receptor(EGFR) Mutations and the Significance in Patients with Non-small Cell Lung Cancer(NSCLC)of Hubei Province
摘要
Abstract
Objective To evaluated the prevalence of EGFR mutations in Hubei region,to provide reliable experimental basis for reasonable screening TKI beneficiaries in clinic.Methods EGFR mutation of 253 patients diagnosed with NSCLC in Hu-bei region during 2010 to 2015 was detected by PCR-sanger sequencing and ARMS assay,to investigate the sensitivity of dif-ferent methods,to explore the frequency and clinical significance of EGFR mutation in different gender,in different histologi-cal type and different exons.Results 93 of 253 NSCLC patients harbored EGFR mutation,mainly occurred in exon 19 and 21,accounting for 53.76% and 35.38% of the total EGFR mutation rate,respectively.ADx-ARMS method showed higher sensitivity (P=0.001).The mutation detection rate of female NSCLC was significantly higher than that of male NSCLC (P=0.001).The observed incidence of EGFR mutations in patients with adenocarcinomas (38.01%)was the highest in differ-ent histological type,followed by glandular squamous cell carcinoma (30.77%),large cell carcinoma (20%)and squamous cell carcinoma (4.55%).Nonsmoking patients had a higher EGFR mutation frequency (51.6%,81/157)than those with a history of smoking (24%,12/50).Conclusion ARMS assay was more sensitive and more convenient detection method for clinical screening for EGFR-TKI treatment subpopulation.The mutation rate of female NSCLC was significantly higher than that of male NSCLC in Hubei Province.Speculated that the sexual differences in NSCLC with EGFR mutation frequencies were related to hormone levels and smoking status.关键词
