摘要
This study aimed to detect mutations in EGFR and KRAS and alterations of c-Met gene copy number (GCN) changes in primary and lymph node-metastatic NSCLCs. The data showed the concordant rate of EGFR genotype in primary and stage N2 lymph node-metastatic tumors was 95.45%. c-Met GCN in stage N2 lymph nodes was significantly higher than that of the primary tumors (P = 0.038). The results suggest both primary and lymph-node metastases have relatively consistent EGFR mutations and EGFR mutations are not relevant to changes in c-Met GCN. c-Met GCN was increased significantly in EGFR TKI-naive patients with lymph node-metastatic tumors.
