ABSTRACT
Squamous cell carcinoma of the head and neck (SCCHN) accounts for 5-7% of all malignancies. About 60% of newly diagnosed SCCHN are detected as locally advanced disease. Chemoradiation is a standard option and response rate to it is variable. Recently, a genetic classification of SCCHN has been proposed by Chung et al., who categorized all SCCHN into four subtypes. The basal-like variant is characterized by high expression of EGFR. Literature data suggest higher efficacy of accelerated and/or hyperfractionated radiotherapy, if compared with conventional radiotherapy in the subgroup of patients with high EGFR expression. In this review, we will describe the genetic factors able to guide treatment choice, with a focus on EGFR expression.
