Analysis of NSCLC data from The Cancer Genome Atlas (TCGA) identified a strong correlation (Spearman correlation coefficient >0.55) among the expression of CXCL9, CXCL10, and their cognate receptor (CXCR3) in both lung adenocarcinoma (LUAD) and lung squamous carcinoma (LUSC) (Figures 1A and 1B). This evidence concerns the gene CXCL9 and non-small cell lung carcinoma.
