Abstract

Head and neck cancer is a challenging disease that is expected to account for greater than 500,000 new cases worldwide in 2008. Toxicity has impeded advances in chemotherapy and radiation for head and neck cancer, and the prognosis for patients with recurrent and/or metastatic disease remains poor. Over the past decade, clinical research in head and neck cancer has focused on improving the efficacy of current multimodal approaches by targeting cellular pathways associated with carcinogenesis. Blocking the epidermal growth factor receptor (EGFR) and the vascular endothelial growth factor receptor (VEGFR) have emerged as primary strategies that account for the success of current targeted therapies in cancer. Recent studies with cetuximab, a monoclonal antibody inhibitor of the EGFR, have demonstrated survival benefits across the range of treatment settings in advanced head and neck cancer, and it is the only targeted therapy approved for use in this malignancy. In this review, the authors present the current development status of targeted therapies, focusing on those that have potential to impact the management of head and neck cancer in the near-term future. Trials are ongoing in all stages of disease and with a variety of modalities and agents, and those trials should provide critical insight into the best way to use these agents to improve patient outcomes.

摘要

头颈癌是一种具有挑战性的疾病,预计2008年全球新增病例将超过50万例。毒性阻碍了头颈癌化疗和放疗的进展,复发和/或转移性疾病患者的预后仍然很差。在过去十年中,头颈癌的临床研究集中在通过靶向与致癌作用相关的细胞途径来提高当前多模式治疗方法的疗效。阻断表皮生长因子受体(EGFR)和血管内皮生长因子受体(VEGFR)已成为主要策略,这也是目前癌症靶向治疗取得成功的原因。近期使用西妥昔单抗(一种EGFR单克隆抗体抑制剂)的研究表明,在晚期头颈癌的各种治疗环境中,它都能带来生存益处,并且它是唯一被批准用于这种恶性肿瘤的靶向治疗药物。在这篇综述中,作者介绍了靶向治疗的当前发展状况,重点关注那些在近期有可能影响头颈癌治疗的药物。针对疾病各个阶段以及各种治疗方式和药物的试验正在进行中,这些试验将为如何最佳使用这些药物以改善患者预后提供关键见解。
