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 ., 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.

摘要

头颈部鳞状细胞癌(SCCHN)占所有恶性肿瘤的5-7%。新诊断的SCCHN中约60%被检测为局部晚期疾病。放化疗是一种标准选择,但其缓解率各不相同。最近,Chung等人提出了SCCHN的基因分类,将所有SCCHN分为四种亚型。基底样变体的特征是表皮生长因子受体(EGFR)高表达。文献数据表明,与传统放疗相比,在表皮生长因子受体高表达患者亚组中,加速和/或超分割放疗疗效更高。在本综述中,我们将描述能够指导治疗选择的遗传因素,重点是表皮生长因子受体表达。
