Stromal TILs were evaluated on whole tissue H&E-stained sections as described previously.Flow charts for the classification of tumors into low-risk and high-risk tumor-intrinsic groups as well as of immune infiltrates as activated or inactivated/absent. *The median score of grade III tumors was used as the cut-off to classify grade II tumors as low-risk or high-risk. PD-1, programmed cell death protein-1; PD-L1, programmed death ligand-1; TILs, tumor-infiltrating lymphocytes.
