47、于特殊的解剖部位和复杂的功能，给恶性肿瘤的治疗提出了挑战。早期头颈癌，无论采用手术或放疗，均能获得良好的效果，无需多手段治疗；但遗憾的是，60%的头颈癌就诊时已属晚期（III、IV期），5年生存率徘徊在10%20%之间。对大多数局部晚期、肿瘤无法切除及需器官保存的肿瘤患者，目前公认的标准治疗是同期化放疗。对肿瘤复发或远处转移的患者，如果肿瘤对铂类或紫杉醇类药物治疗不敏感，则只能给予患者支持治疗。诱导化疗（induction chemotherapy）是指手术或放疗前进行的化疗，又称为新辅助化疗（neoadjuvant chemotherapy），作为肿瘤化学治疗的一种方式，用于头颈鳞癌已有近3
48、0年的历史，但其在肿瘤治疗中的确切作用一直颇受争议。争论的焦点是在提高局部控制率和生存率方面的确切作用，争议产生的主要原因，是其理论上明显的优势与以往临床试验显示诱导化疗对患者生存率没有明显改善之间的矛盾。文献报道的各种诱导化疗方案的随机对照试验（RCT）结果不一，有些称显著有效，有些则认为无效，但多数研究认为，PF诱导化疗虽然暂时有效甚至显效，但不能显著提高这类患者的远期生存率。屠规益教授认为：从临床医师的角度而言，我们要求的是确实（有“根治性”）有效的实用方案，可以在临床上重复应用。迄今为止，化疗在恶性肿瘤尤其是造血系统肿瘤的治疗中已经发挥了很大作用。但是，无论是新药还是常规药物、无论是单
49、药还是多种药物联合应用、无论是单独化疗或综合（放疗、手术）应用，对头颈鳞癌尚没有确切的“根治性疗效”，尚没有确实可以加强其他治疗手段的结果报告。建议目前临床上不宜对头颈鳞癌患者常规应用化疗作为根治性治疗或辅助措施。China J Oral Maxillofac Surg,2006,4(3):162-165.Marshall R.Posner 教授（Dana Farber癌症研究所，波士顿马萨诸塞，美国）认为：联合应用顺铂与5氟尿嘧啶一直被视为标准新辅助治疗，术前化疗能够降低肿瘤的远处转移率，但其在提高患者生存率方面并没有足够证据。China J Oral Maxillofac Surg,200
50、6,4(5):322-329.目前的结论诱导化疗对提高肿瘤局部控制率的作用：最初将诱导化疗应用于头颈晚期鳞癌的治疗，目的是为了提高局部控制率，达到提高生存率的目的。但临床研究中并没有足够的证据表明，诱导化疗能够有效提高手术对头颈部鳞癌的控制率。这是因为局部控制率的提高，一方面依赖于诱导化疗的疗效，量效不够的诱导化疗、肿瘤对化学药物的低反应率反而影响了局部治疗的效果；另一方面，头颈晚期鳞癌是异质性非常大的一族疾病群，手术治疗的效果在很大程度上决定于患者的发病部位、病变范围以及周围的解剖关系。诱导化疗对远处转移的抑制作用：有效地减少远处转移率，是诱导化疗对肿瘤治疗的一大优势。Paccagnella
