Sun et al retrospectively generated a contrast‐enhanced CT‐based radiomics signature of tumour‐infiltrating CD8 cells and investigated its performances in predicting tumour immune phenotype (immune‐inflamed vs immune‐desert) and response to anti‐programmed cell death protein (PD)‐1 or anti‐programmed cell death ligand 1 (PD‐L1) monotherapies.95 This evidence concerns the gene CD8A and neoplasm.
