Core Tip

Core Tip: This study found that high neutrophil extracellular trap (NETs) levels in patients with non-small cell lung cancer were associated with poor chemotherapy immunotherapy outcomes. Further study found that 54 different metabolites existed between the high NET and low NET groups. Through screening by a machine learning algorithm, three metabolites, 8,9-epoxy-eicosatrienoic acid, L-malate, and bis(monoacylglycerol)phosphate (18:1/16:0), were found to be biomarkers to predict the effect of chemoimmunotherapy in non-small cell lung cancer patients. This study provided important clues to understanding the relationship between NET levels and the effect of chemoimmunotherapy.
