Immune checkpoint blockade is promising for treating non-small-cell lung cancer (NSCLC). We used multipanel markers to predict the response to immune checkpoint inhibitors (ICIs) by characterizing gene expression signatures or individual genes in patients who showed durable clinical benefit to ICIs. Twenty-one patients with NSCLC treated with single-agent anti-programmed cell death protein (PD)-1 antibody were analyzed and their clinicopathological characteristics and response to ICIs were characterized. Nine (43%) showed a durable clinical benefit (DCB), while the remaining 12 (57%) patients showed non-durable benefit (NDB). The M1 and peripheral T cell signatures showed the best performance for discriminating DCB from NDB (sensitivity, specificity, accuracy = 0.89, 1.0, 0.95, respectively). Progression-free survival (PFS) was significantly longer in patients with high M1 signature or high peripheral T cell signature scores. CD137 and PSMB9 mRNA expression was higher in the DCB group than in the NDB group. Patients with high PSMB9 expression showed longer PFS. M1 signature, peripheral T cell signature and high mRNA expression level of CD137 and PSMB9 showed better predictive performance than known biomarkers, such as PD-L1 immunohistochemistry, tumor mutation burden, or tumor-infiltrating lymphocytes.

用于预测抗 PD-1 免疫疗法对非小细胞肺癌患者持久临床益处的免疫基因特征。



免疫检查点阻断有望治疗非小细胞肺癌(NSCLC)。我们使用多组标记物通过表征对 ICI 表现出持久临床益处的患者的基因表达特征或个体基因来预测对免疫检查点抑制剂 (ICIs) 的反应。对 21 名接受单药抗程序性细胞死亡蛋白 (PD)-1 抗体治疗的 NSCLC 患者进行了分析,并描述了他们的临床病理特征和对 ICI 的反应。 9 名 (43%) 患者表现出持久临床获益 (DCB),而其余 12 名 (57%) 患者表现出非持久获益 (NDB)。 M1 和外周 T 细胞特征显示区分 DCB 和 NDB 的最佳性能(敏感性、特异性、准确性分别 = 0.89、1.0、0.95)。具有高 M1 特征或高外周 T 细胞特征评分的患者的无进展生存期 (PFS) 显着更长。 DCB组中CD137和PSMB9 mRNA表达高于NDB组。 PSMB9 高表达的患者表现出更长的 PFS。 M1 特征、外周 T 细胞特征以及 CD137 和 PSMB9 的高 mRNA 表达水平显示出比已知生物标志物(例如 PD-L1 免疫组织化学、肿瘤突变负荷或肿瘤浸润淋巴细胞)更好的预测性能。
