Role and mechanisms of resistance of epidermal growth factor receptor antagonists in the treatment of colorectal cancer

摘要

Introduction: Although epidermal growth factor receptor (EGFR) inhibitors have progressively become a relevant therapeutic arm in the treatment of patients with advanced colorectal cancer, the responses achieved are not durable and resistance invariably occurs. The advances in sequencing technology have allowed not only a more profound molecular tumor characterization but also the identification of the different molecular pathways involved in drug resistance and disease progression. These biological improvements have encouraged researchers to design clinical studies testing novel target therapies.
