Stratification strategies for chemotherapy plus PD-1 inhibitors in advanced non-small-cell lung cancer (NSCLC) are critically demanded. We performed high-throughput panel-based deep next-generation sequencing and low-pass whole genome sequencing on prospectively collected circulating tumor DNA (ctDNA) specimens from 460 patients in the phase 3 CHOICE-01 study at different time points. We identified predictive markers for chemotherapy plus PD-1 inhibitor, including ctDNA status and genomic features such as blood-based tumor mutational burden, intratumor heterogeneity, and chromosomal instability. Furthermore, we established an integrated ctDNA-based stratification strategy, blood-based genomic immune subtypes (bGIS) scheme, to distinguish patients who benefit from the addition of PD-1 inhibitor to first-line chemotherapy. Moreover, we demonstrated potential applications for the dynamic monitoring of ctDNA. Overall, we proposed a potential therapeutic algorithm based on the ctDNA-based stratification strategy, shedding light on the individualized management of immune-chemotherapies for patients with advanced NSCLC.

晚期非小细胞肺癌化疗加 PD-1 抑制剂的循环肿瘤 DNA 分层策略



迫切需要化疗加 PD-1 抑制剂治疗晚期非小细胞肺癌 (NSCLC) 的分层策略。我们对 3 期 CHOICE-01 研究中 460 例患者在不同时间点前瞻性收集的循环肿瘤 DNA (ctDNA) 标本进行了高通量基于面板的深度下一代测序和低通全基因组测序。我们确定了化疗加 PD-1 抑制剂的预测标志物,包括 ctDNA 状态和基因组特征,例如基于血液的肿瘤突变负荷、肿瘤内异质性和染色体不稳定性。此外,我们建立了一种基于 ctDNA 的综合分层策略,即基于血液的基因组免疫亚型 (bGIS) 方案,以区分在一线化疗中加入 PD-1 抑制剂的患者。此外,我们展示了 ctDNA 动态监测的潜在应用。总体而言,我们提出了一种基于基于 ctDNA 的分层策略的潜在治疗算法,阐明了晚期 NSCLC 患者免疫化疗的个体化管理。
