多年来,NCCN指南中对于局部晚期非小细胞肺癌(LANSCLC)推荐采用同步放化疗作为规范治疗,均是1类或2A类证据,这是许多肺癌专家不断探索、研究的结果。

从LANSCLC治疗策略上看,主要有4点:①放化综合治疗优于单纯放疗;②放化综合治疗优于单纯化疗;③放化疗综合治疗与手术效果相似;④同步放化疗优于序贯放化疗。本报告将对以上治疗策略相关研究进行详细说明,并对LANSCLC同步放化疗适应证与禁忌证、同步放化疗中放疗与化疗规范、同步放化疗应用时机等内容展开介绍。

尽管对于不能手术切除的III期NSCLC患者推荐同步放化疗为标准治疗,但能获得治愈的患者仍不到1/3,因此如何提高同步放化疗的效果成为近年研究的热点。体外实验证明,C225对NSCLC细胞系具有放射增敏作用,那么分子靶向药物与放化疗联合使用是否能够提高疗效呢?

一项II期临床研究显示,局部晚期NSCLC患者可以耐受西妥昔单抗(C225)与放化疗联合应用,且治疗的中位生存期和2年生存率高于RTOG以往的报道。2008年ASCO年会报道了另一项II期随机临床研究-CALGB30407试验,结果显示C225与放化疗同期使用耐受性良好。上一届世界肺癌大会,美国报告美国放疗肿瘤协作组(RTOG)0617关于局部晚期非小细胞肺癌同步放化疗联合C225的III期随机对照研究结果,同步放化疗中加与不加C225不影响患者的生存。上述结果表明,靶向联合的问题仍有待研究。

同步放化疗是局部晚期非小细胞肺癌的标准治疗,有严格的适应证、禁忌证,放疗、化疗都有章可循,肺癌专家应当努力做好,提高此类患者的五年生存率。
