Abstract
BACKGROUND: Status of epidermal growth factor receptor (EGFR) gene is a predictor of response to EGFR tyrosine kinase inhibitor (TKI). However, little is know about the relationship between EGFR status and response to chemotherapy. We evaluated the prediction value of EGFR mutation status on response to first-line chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC).Entities:
