摘 要:Immune checkpoint inhibitors targeting the programmed cell death-1(PD-1)protein significantly improve survival in patients with advanced non-small-cell lung cancer(NSCLC),but its impact on early-stage ground-glass opacity(GGO)lesions remains *** is a single-arm,phase II trial(NCT04026841)using Simon’s optimal two-stage design,of which 4 doses of sintilimab(200 mg per 3 weeks)were administrated in 36 enrolled multiple primary lung cancer(MPLC)patients with persistent high-risk(Lung-RADS category 4 or had progressed within 6 months)*** primary endpoint was objective response rate(ORR).T/B/NK-cell subpopulations,TCR-seq,cytokines,exosomal RNA,and multiplexed immunohistochemistry(mIHC)were monitored and compared between responders and ***,two intent-to-treat(ITT)lesions(pure-GGO or GGO-predominant)showed responses(ORR:5.6%,2/36),and no patients had progressive disease(PD).No grade 3-5 TRAEs *** total response rate considering two ITT lesions and three non-intent-to-treat(NITT)lesions(pure-solid or solid-predominant)was 13.9%(5/36).The proportion of CD8^(+)T cells,the ratio of CD8^(+)/CD4^(+),and the TCR clonality value were significantly higher in the peripheral blood of responders before treatment and decreased over ***,the mIHC analysis showed more CD8^(+)T cells infiltrated in ***,responders’cytokine concentrations of EGF and CTLA-4 increased during *** exosomal expression of fatty acid metabolism and oxidative phosphorylation gene signatures were down-regulated among ***,PD-1 inhibitor showed certain activity on high-risk pulmonary GGO lesions without safety *** effects were associated with specific T-cell re-distribution,EGF/CTLA-4 cytokine compensation,and regulation of metabolism pathways.
