(27),who used immunogenomic techniques to assess the immunological tumour microenvironment and discovered six immune subgroups (wound healing [C1], IFN-γ dominant [C2], inflammatory phenotype [C3], lymphocyte depleted [C4], immunologically quiet [C5] and TGF-β dominant [C6]) using >10,000 tumour samples across 33 TCGA cancer types. This evidence concerns the gene TGFB1 and neoplasm.
