Abstract

Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment landscape for non-small cell lung cancer (NSCLC). The variability in patient responses necessitates a blood-based, multi-cohort gene signature to predict ICI response in NSCLC.

Methods: We performed transcriptomic profiling of peripheral blood mononuclear cell (PBMC) and buffy coat (BC) samples from three independent cohorts of NSCLC patients treated with ICIs: a retrospective cohort (PMBCR, n = 59), a retrospective validation cohort (BC, n = 44), and a prospective validation cohort (PBMCP, n = 42). We identified a 5-gene signature (UQCRB, NDUFA3, CDKN2D, FMNL1-DT, and APOL3) predictive of ICI response and validated its clinical utility in the prospective PBMCP cohort. Response was evaluated using RECIST criteria, and patients were followed up for progression-free survival (PFS) and overall survival (OS).

Results: In the prospective PBMCP cohort, the 5-gene signature demonstrated high accuracy in stratifying patients into responders and non-responders (AUC = 0.89, 95% CI: 0.80-0.99). Predicted responders exhibited significantly longer PFS compared to predicted non-responders (median: 13.8 months vs. 4.2 months, HR = 0.21, 95% CI: 0.07-0.58, p = 0.005).

Conclusion: Our study confirms a 5-gene signature as a key biomarker for ICI response in NSCLC, enhancing treatment precision.

Survival Analysis Demonstrating the Prognostic Value of the 5-Gene Signature. A: Kaplan-Meiercurves for progression-free survival (PFS) in the PMBCR cohort, revealing a significant survival benefit for patientspredicted as responders by the 5-gene signature compared to predicted non-responders (P < 0.001). B: Kaplan-Meier curves for PFS in the prospective PBMCP cohort, confirming the prognostic value of the 5-gene signature,with predicted responders exhibiting significantly longer PFS than predicted non-responders (P < 0.001). C: Kaplan-Meier curves for PFS in the BC cohort, demonstrating a significant survival advantage for predicted respondersover predicted non-responders based on the 5-gene signature (P < 0.001). D: Kaplan-Meier curves for overallsurvival (OS) in the BC cohort, showing a significant survival benefit for patients predicted as responders by the 5-gene signature compared to predicted non-responders (P < 0.001)
