Immunohistochemical staining of TILs in samples from PDAC patients following surgical resection. Quantitative scoring of the TILs surrounding ten random tumor areas in PDAC samples was performed. The average of cell counts/mm2 tumor area was graded as low density (≤ median cell counts/mm2 tumor area) or high density (> median cell count/mm2 tumor area). Negative control samples were stained with a nonspecific IgG antibody. PDAC, pancreatic ductal adenocarcinoma; TIL, tumor-infiltrating lymphocyte; IgG: immunoglobulin G
