EGFR-targeted therapy

Anti-Epidermal Growth Factor Receptor (EGFR) therapies have been recently developed for the treatment of multiple cancer types. At the time when they were introduced in clinical practice, there was little knowledge of the molecular bases of tumor sensitivity and resistance to these novel targeted compounds. By using the framework of anti-EGFR inhibitors as treatment for colorectal cancer patients, we will review the knowledge we have reached until now in improving the development of a personalized cancer therapy and we will try to indicate the future challenges this field will face in the future.
