抗生素对派姆单抗治疗的NSCLC患者的预后具有显著的负性效应

在未选择的非小细胞肺癌(NSCLC)患者中,包括抗生素(ATB)在内的一些伴随药物,与免疫检查点抑制剂(ICI)治疗的存活较差有关,且该相关性具有可重复性。但是,这种相关性具体是因果关系还是关联关系仍存在争议。

近日发表在《癌症免疫治疗杂志》“J Immunother Cancer”上的一篇文章概述了在一项关于接受一线派姆单抗单药治疗的PD-L1表达≥50%的转移性NSCLC患者的大规模队列研究中根据伴随基础药物(在ICI治疗前)和可能的免疫调节作用进行的预后分析。此外,研究人员还评估了接受一线化疗治疗的转移性NSCLC患者的对照队列。最后,在汇总的多变量分析中验证了关键药物与治疗方式(派姆单抗 vs 化疗)之间的相互作用。

派姆单抗和化疗队列分别纳入了950位和595位患者。在两个治疗队列中,皮质类固醇和质子泵抑制剂(PPI)治疗均与基线时较差的表现状态相关,但ATB治疗与此无关。在派姆单抗组中,基线时应以他汀类药物、阿司匹林,β受体阻滞剂和二甲双胍均与患者临床预后无关联。

总生存期分析

在多变量分析中,ATB可以作为派姆单抗组总体生存期(OS)和无进展存活期(PFS)较差的强有力的预测因素(HR分别为1.42和1.29;p值分别为0.0024和0.0192),但在化疗组中无此相关性。

无进展生存期分析

派姆单抗治疗或化疗后予以皮质类固醇均与较短的PFS(HR分别为1.69和1.30, p<0.0001)和OS(1.93和1.58,p<0.0001)有关。PPIs与派姆单抗治疗的OS更短(HR 1.49,p<0.0001)和化疗的OS更短(HR 1.12,p=0.0139)相关

在汇总分析中,就OS而言,皮质类固醇和PPI与治疗(派姆单抗vs化疗)之间存在统计学意义的交互作用(p值分别为0.0020和0.0460);就PFS而言,皮质类固醇、ATB和PPI与治疗(派姆单抗vs化疗)之间存在统计学意义的交互作用(p值分别<0.0001、0.0290和0.0487);就客观缓解率而言,只有皮质类固醇与治疗存在交互作用(p=0.0033)。

综上所述,该研究证明了ATB对NSCLC患者采用派姆单抗单药治疗的预后具有显著的负性效应,但对其采用化疗无明显影响,进一步证明了它们之间潜在免疫调节作用。虽然在整个研究队列中,皮质类固醇和PPI的影响程度存在显著差异,但其影响可能是由不良疾病特征驱动的,而非因果关系
