Relationships of fluorine-18 fluorodeoxyglucose (18F-FDG) uptake on positron emission tomography/computed tomography (PET/CT) with programmed death-ligand 1 (PD-L1) expression and cluster of differentiation 8 (CD8) + and forkhead box protein P3 (Foxp3) + tumor-infiltrating lymphocyte (TIL) counts. The rate of PD-L1 positivity in patients with a high maximum standardized uptake value (SUVmax) of 18F-FDG was significantly higher than those with low SUVmax (A). CD8 + TIL counts in patients with high SUVmax of 18F-FDG were lower than those with low SUVmax (B). Foxp3 + TIL counts in patients with high SUVmax of 18F-FDG were higher than those with low SUVmax (C).
