CD8A and neoplasm: We observed that the presence of TILs (tumor infiltrating lymphocytes) (CD3D+, CD8A+ T cells) in a subset of our cohort (n = 8; 50%) served as a classifier that clearly distinguished favorable64 TILhigh and TILlow subgroups (CD3D, p = 2.8e−07; CD8A, p = 2.6e−04) of MBM (Fig. 3d).
