The road to resistance: EGFR mutation and cetuximab

Some individuals with colorectal cancer benefit from therapies targeting the epidermal growth factor receptor (EGFR). However, resistance to EGFR blockade inevitably occurs. The characterization of a new mechanism of resistance to the EGFR-specific antibody cetuximab provides clues into how therapeutic strategies might be designed to overcome this specific resistance mechanism (pages 221–223).
