Expression of insulin-like growth factor 1 receptor (IGF-1R) predicts poor responses to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non-small cell lung cancer patients harboring activating EGFR mutations.

Abstract excerpt

OBJECTIVES: Expression of insulin-like growth factor 1 receptor (IGF-1R) in non-small cell lung cancer (NSCLC) is associated with poor prognosis. The IGF-1R pathway activates downstream targets that bypass dependency in signals from the epidermal growth factor receptor (EGFR), which mediates resistance to EGFR tyrosine kinase inhibitors (TKIs). The aim of the present study was to determine the predictive role of...
