Squamous cell carcinoma of the larynx is a major public health concern; it causes substantial morbidity and mortality, and arises chiefly as a result of tobacco and alcohol consumption. Early stage disease is best treated with radiation or surgery alone, but for patients with more locally advanced squamous cell carcinoma of the larynx, combined modality treatment has been shown to benefit selected patients, particularly when cisplatin-based chemotherapy and concurrent radiation therapy are employed, with or without altered fractionated radiation therapy. Substantial laryngectomy-associated quality-of-life decrements can be avoided in selected, potentially resectable patients with organ-sparing approaches, without sacrificing survival. Recently, trials have addressed the role of targeted systemic agents to the epidermal growth factor receptor, and other targets are under investigation. The addition of induction chemotherapy to concurrent chemoradiotherapy is a promising treatment strategy that warrants further evaluation, but has not yet emerged as a standard of care; the toxicity of such regimens must be balanced with the potential benefits on a case-by-case basis, and functional outcomes are often quite variable. Treatment planning, management and follow-up are complex, and thus should ideally be performed in a comprehensive, multidisciplinary fashion, in a center accustomed to a high volume of such cases. Future research directions are described herein.
喉鳞状细胞癌是一个重大的公共卫生问题;它会导致严重的发病和死亡,主要是由吸烟和饮酒引起的。早期疾病最好单独采用放疗或手术治疗,但对于局部进展性更强的喉鳞状细胞癌患者,联合治疗已被证明对部分患者有益,特别是在采用以顺铂为基础的化疗和同步放疗时,无论是否采用改变分割的放疗。在部分有保留器官可能的可切除患者中,采用保留器官的方法可避免与喉切除术相关的生活质量大幅下降,且不影响生存率。最近,试验探讨了针对表皮生长因子受体的靶向全身药物的作用,其他靶点也在研究中。在同步放化疗中加入诱导化疗是一种有前景的治疗策略,值得进一步评估,但尚未成为标准治疗方法;此类方案的毒性必须根据具体情况与潜在益处相权衡,而且功能结果往往差异很大。治疗计划、管理和随访都很复杂,因此理想情况下应在一个处理大量此类病例的中心,以全面、多学科的方式进行。本文描述了未来的研究方向。
