Abstract

Targeted therapy is an effective method for treatment of non small cell lung cancer (NSCLC), especially in patients group carrying EGFR, EML4-ALK, ROS1 mutation. However, not all of patients have good response with targeted drugs. Many previous studies demonstrated the close relationship between EGFR and EML4-ALK, ROS1 rearrangement mutation and the response of targeted drugs with tumor. Objectives: Identifying EGFR mutation and EML4-ALK, ROS1 rearrangement mutations in NSCLC patients by realtime PCR and FISH methods. Methods: 135 NSCLC patients were selected for this study; realtime PCR and FISH methods were used to identify EGFR mutation and EML4-ALK, ROS1 rearrangement mutation. Results: 69/135 (51,1%) of NSCLC patients have mutation in exon 19, 20 and 21 of EGFR gene; 9/135 (6,7%) of NSCLC patients have EML4-ALK rearrangement mutation and 3/135 (2,2%) of NSCLC patients have ROS1 rearrangement mutation.
