IPTS positively correlates with immune microenvironment score and expression of immune-related genes signatures. A Histograms based on IPTS molecular typing and tumor microenvironment (TME)-related enrichment scores; B histograms based on IPTS molecular typing and enrichment scores of the five immune molecular typing; C histogram based on IPTS molecular typing and TPM values of four immune checkpoints sequenced in TCGA-LUSC database; D–F Scatter plot of correlations based on IPTS and D stromal scores, E immune scores, and F ESTIMATE scores. G–J Scatter plot of correlations based on IPTS and expression of G CTLA-4, H PD-1, I PD-L1, and J PD-L2. ****P < 0.0001
