The epidermal growth factor receptor in squamous cell carcinoma: An emerging drug target

Abstract

Squamous cell carcinoma (SCC) of the skin is an increasingly common diagnosis worldwide. Together with precursor lesions, SCC carry a significant morbidity, particularly in regions with high solar UV radiation levels. Advanced lesions are locally or sometimes widely metastatic and may be resistant to treatment. Drugs targeting the epidermal growth factor receptor (EGFR) are currently the only significant non-surgical option for advanced SCC beyond radiotherapy and conventional chemotherapy. The role of the EGFR in skin cancer is described and the outcomes of targeted anti-EGFR therapy published to date are summarised. The future of anti-EGFR targeted therapies in the treatment of skin cancer is discussed. Targeted molecular therapies are becoming increasingly widespread and an understanding of the evidence for their use as well as their side effect profile is important in order to offer patients informed and current advice. © 2013 The Australasian College of Dermatologists.
