Association between higher glucose levels and reduced survival in patients with non-small cell lung cancer treated with immune checkpoint inhibitors

Background: Obesity and hypercholesterolemia have been associated with better responses to ICIs in NSCLC, while type 2 diabetes (T2D) has been associated with a worse response. However, the association between glucose levels and outcomes remains unknown. This study investigated the impact of mean baseline glucose levels, T2D, dyslipidemia, and obesity on overall survival (OS) in NSCLC patients undergoing ICI therapy.

Methods: A multicenter retrospective cohort study was conducted using data from three medical centers, with locally advanced or metastatic NSCLC patients receiving ICI, regardless of treatment line or concurrent therapy. Random venous glucose levels within 4 weeks prior to ICI initiation, BMI, history of dyslipidemia, and T2D, along with OS, were assessed. Patients with BMI < 18.5 were excluded.

Results: Among 438 patients, those with the highest quartile of baseline glucose levels had signif icantly shorter OS compared to those in the lowest quartile (HR, 1.53; 95 % CI, 1.08 – 2.15; p-value = 0.016). This association remind consistent after adjusting for steroid use, diabetes, performance status and glucose-lowering medication use. These effects were consistently observed in subsets of patients treated with ICI monotherapy and with PD-L1 TPS ≥ 1 %.

Conclusion: Higher mean baseline glucose levels correlated with shorter survival in patients with NSCLC treated with ICIs. The divergent effects of individual metabolic syndrome components on ICI response in patients with NSCLC underscore the complexity of metabolic influences on treatment outcomes. © 2024 Elsevier B.V.
