JCO:Nivolumab治疗晚期非小细胞肺癌的5 年随访结果

2018-03-25 MedSci MedSci原创

在两项Ⅲ期临床试验中,Nivolumab,一种PD-1抑制剂抗体,与多西他赛相比可以改善进行过治疗的晚期非小细胞肺癌患者的总生存率。JCO近期发表了一篇文章,报道了Nivolumab治疗这类人群的早期Ⅰ期临床试验的5年随访结果并描述5年生存患者的特征。

在两项Ⅲ期临床试验中,Nivolumab,一种PD-1抑制剂抗体,与多西他赛相比可以改善进行过治疗的晚期非小细胞肺癌患者的总生存率。JCO近期发表了一篇文章,报道了Nivolumab治疗这类人群的早期Ⅰ期临床试验的5年随访结果并描述5年生存患者的特征。

既往接受过治疗的晚期非小细胞肺癌患者在8周周期内每2周接受Nivolumab1,3,或10mg/kg治疗,最长达96周。使用K-M曲线评估总生存情况。研究结果表明,所有患者5年总生存率为16%。鳞状细胞和非鳞状细胞非小细胞肺癌患者的5年总生存率相似。10例可以评估PD-L1表达的5年生存患者中,70%基线PD-L1表达≥1%。12例5年生存患者接受Nivolumab治疗后达到了部分缓解,2例病情稳定。9例5年生存患者完成了最高的96周期Nivolumab治疗,4例由于不良反应中断治疗,3例由于疾病进展中断治疗。在2016年11月数据库截止时,12例5年生存患者未接受其他治疗且在最后随访时也没有疾病进展的证据。

文章最后认为,Nivolumab在进行过治疗的晚期非小细胞肺癌部分患者中可以出现病情持续缓解并延长总生存期。长期生存患者基线及治疗过程中的特征差异很大。
