To further characterize the immune microenvironment according to the six pan‐cancer immune subtypes defined by Thorsson et al. (2018), we derived sample‐based enrichment scores from the five representative gene sets described in the paper: (a) activation of macrophages/monocytes, (b) overall lymphocyte infiltration, (c) TGF‐β response, (d) IFN‐γ response, and (e) wound healing (Fig. 2B). Here, TGFB1 is linked to cancer.
