Therefore, we explored the correlation between tumour volume and the expression score of different gene sets, including Pdl1, IFN-γ, IFN-γ signature (6-gene), IFN-γ signature (10-gene), antigen-processing machinery and major histocompatibility complex class I and II gene expression (APC-MHC) score (15-gene), preliminary expanded immune (28-gene), expanded immune signature (18-gene), effector T cell gene set (6-gene), IFN-γ and T effector gene set (8-gene), and chemokine gene set (9-gene). Here, HLA-C is linked to neoplasm.
