Abstract
BACKGROUND: Genetic variations of the epidermal growth factor receptor (EGFR) may alter the protein function and therapeutic efficacy of EGFR inhibitors. The aim of this study is to investigate the association between single nucleotide polymorphism rs2293347 in EGFR and the clinical outcome in patients with advanced non-small cell lung cancer (NSCLC) treated with gefitinib.Entities:
