Lung Cancer:II/IIIA期NSCLC,长期S-1单药作为术后辅助治疗是否可行?

肺癌是目前发病率和死亡率最高的恶性肿瘤之一,其中非小细胞肺癌(NSCLC)是主要的类型。2018年10月,发表在《Lung Cancer》的一项II期随机开放标签多机构研究调查了,长期S-1单药治疗作为NSCLC患者术后辅助治疗是否有效。

肺癌是目前发病率和死亡率最高的恶性肿瘤之一,其中非小细胞肺癌NSCLC)是主要的类型。2018年10月,发表在《Lung Cancer》的一项II期随机开放标签多机构研究调查了,长期S-1单药治疗作为NSCLC患者术后辅助治疗是否有效。

目的:基于铂的联合化疗是病理分期II/III期NSCLC的标准术后辅助治疗。对于晚期NSCLC的治疗,口服S-1具有良好的疗效和相对低的毒性。研究人员调查了长期S-1单药治疗作为NSCLC患者术后辅助治疗是否也是有用的。

患者和方法:研究人员进行了一项II期随机开放标签多机构研究,研究对象为2009~2013年完全切除的病理分期II/IIIA期NSCLC(第七版TNM分级)患者。首要终点指标为2年无疾病生存(DFS)率,使用Bayesian方法评估。符合条件的患者随机分配到两组:口服S-1单药治疗(S-1组,第1~14天口服S-1 80mg/m2,每3周一次,共1年);S-1+顺铂联合治疗后S-1(S-1+顺铂组,第1~21天口服S-1 80mg/m2,每5周一次,+第8天顺铂60mg/m2,每5周一次,4个疗程;之后是第1~14天口服S-1 80mg/m2,每3周一次,共1年),两组都治疗1年。

结果:S-1组和S-1+顺铂组分别总共纳入70和71名患者。S-1和S-1+顺铂组的2年DFS率分别为52%(95% CI,0.40~0.63)和61%(95% CI,0.48~0.70)。两组都满足首要终点。组间DFS和OS都无显著性差异(对数秩检验,P分别为0.1695和0.8684)。主要3/4级不良事件为食欲不振和贫血(S-1 vs S-1+顺铂:4.3% vs 11.6%和0% vs 5.8%)。组间治疗完成率无差异(45.7%(95% CI,41.9~66.3)vs 43.5%(95% CI,44.0~68.4))。

结论:对于完全切除的NSCLC患者,长期S-1辅助化疗是可行的,是有前景的治疗方法,不论是否添加顺铂都是如此。应该基于其较低的毒性和实用的便利性进一步调查S-1单药治疗。
