Epidermal Growth Factor Receptor Gene Polymorphisms Predict Pelvic Recurrence in Patients with Rectal Cancer Treated with Chemoradiation

Abstract excerpt

An association between epidermal growth factor receptor (EGFR) signaling pathway and response of cancer cells to ionizing radiation has been reported. Recently, a polymorphic variant in the EGFR gene that leads to an arginine-to-lysine substitution in the extracellular domain at codon 497 within subdomain IV of EGFR has been identified. The variant EGFR (HER-1 497K) may lead to attenuation in ligand binding,...
