1 Epidermal growth factor receptor (EGFR) is a transmembrane receptor tyrosine kinase involved in the signaling pathways that regulate cell proliferation, apoptosis, angiogenesis, and invasion. Epidermal growth factor receptor mutation is associated with response to therapy in resected advanced non-small-cell lung cancer. 2  Nuclear EGFR protein expression predicts poor survival in early stage non-small cell lung cancer. 3  EGFR activating mutations are associated with brain metastases in non-small lung cancer.
