Nat Commun:检查点免疫治疗过程中不良事件的多组学预测

2020-10-03 haibei MedSci原创

抗程序性死亡1(PD-1)或抗程序性死亡配体1(PD-L1)抗体治疗过程中的免疫相关不良事件(irAEs),由于免疫激活与免疫平衡紊乱相结合,可影响任何器官系统,在某些情况下甚至可致死。

抗程序性死亡1(PD-1)或抗程序性死亡配体1(PD-L1)抗体治疗过程中的免疫相关不良事件(irAEs),由于免疫激活与免疫平衡紊乱相结合,可影响任何器官系统,在某些情况下甚至可致死。

肺炎,最常见的致命irAE,可以导致10%的死亡率,占抗PD-1/PD-L1相关死亡病例的35%。心肌炎,最致命的irAE,可导致约50%的死亡率。因此,我们需要irAEs的预测性生物标志物来确定接受抗PD-1/PD-L1治疗的患者的获益/风险比。

T细胞受体(TCR)多样性,CD8+T细胞克隆扩张,和肿瘤突变负担(TMB)已被建议可能用于预测irAE,但是它们是基于单一因素或在有限的病例中进行的。因此,至今为止,我们缺乏一个全面的方法来确定irAE的生物标志物。特别是,获得具有足够样本量的患者样本队列是具有挑战性的,基于传统的方法可能需要多年的多中心研究。

最近,研究人员在Nature Communications杂志发文,其通过整合现实世界的药物警戒和分子omics数据,调查了接受抗PD-1/PD-L1治疗的26种肿瘤类型患者中irAE风险的潜在预测因素。

研究人员确定了能够准确预测irAE的LCP1和ADPGK的双变量线性回归模型,并在一个独立的患者队列中验证了LCP1+ADPGK模型的预测潜力。

因此,该方法为利用药物警戒数据和多组学数据识别癌症免疫治疗中irAE的潜在生物标志物提供了一种方法。
