Abstract: | Epidermal growth factor receptor (EGFR) is highly expressed in head and neck cancer (HNC). Since EGFR has a large extracellular ligand binding as well as an intracellular tyrosine kinase domain, anti-EGFR therapy may involve anti-ligand binding domain antibody- or tyrosine kinase inhibitor therapies. Phase II-III studies confirmed the efficacy of anti-EGFR antibody therapy in case of squamous cell HNC. In combination with irradiation, anti-EGFR antibody therapy improved survival of locally advanced HNC patients. In case of recurrent or metastatic HNC, anti-EGFR antibody therapy in combination with chemotherapy significantly increased remission rate without increasing toxicity. Although studies on EGFR kinase inhibitors in HNC are in early phase, preliminary data are encouraging. |
