Lancet:诱导化疗治疗IIIA/N2期非小细胞肺癌

2015-08-13 崔倩 译 MedSci原创

IIIA/N2期非小细胞肺癌的治疗标准选择之一是新辅助化疗和手术。研究人员做了一项随机试验,探讨增加新辅助放疗能否可以改善预后。研究人员在瑞士,德国和塞尔维亚的23个中心招募患者参加研究。符合条件的患者已经病理证实为IIIA/N2期非小细胞肺癌患者,被随机以1:1的比例分配到治疗组中。那些化疗组中的患者接受三个周期的新辅助化疗(100mg/m2的铂和85mg/m2的多西他赛),随后进行3周44Gy

IIIA/N2期非小细胞肺癌的治疗标准选择之一是新辅助化疗和手术。研究人员做了一项随机试验,探讨增加新辅助放疗能否可以改善预后。

研究人员在瑞士,德国和塞尔维亚的23个中心招募患者参加研究。符合条件的患者已经病理证实为IIIA/N2期非小细胞肺癌患者,被随机以1:1的比例分配到治疗组中。那些化疗组中的患者接受三个周期的新辅助化疗(100mg/m2的铂和85mg/m2的多西他赛),随后进行3周44Gy 22次分割的放疗,而对照组患者只接受单独新辅助化疗。所有患者均计划进行手术。随机进行分层通过中心,纵隔体(小于5cm vs 5cm以上),体重损失(在过去6个月5%或更多 vs 小于5%)。主要终点是无事件生存期。通过意向治疗进行分析。

从2001年到2012年,232名患者参加本研究,其中117人分配到放化疗组,115人被分配到单纯化疗组。两组的中位无事件生存期是相似的,放化疗组12.8个月(95%Cl 9.7-22.9),单纯化疗组为11.6个月(8.4-15.2)(p=0.67)。放疗的患者中位总生存期为37.1个月(95%Cl 22.6-50.0),对照组为26.2个月(19.9-52.1)。化疗相关的毒性作用在大多数患者中有报道,但91%的患者完成了化疗的三个周期。7例(7%)患者发生放疗引起的3级吞咽困难。对照组的3例患者在手术后30天内死亡。

放疗没有增加手术后诱导化疗的任何好处。研究人员建议,一个最终的局部治疗形式联合新辅助化疗足以治疗可切除的IIIA/N2期的非小细胞肺癌。
