Evaluating tumor-infiltrating lymphocytes in hepatocellular carcinoma using hematoxylin and eosin-stained tumor sections

Figure 4 The pathological picture and recurrence association of programmed cell death-ligand 1 SP142 expression in tumor cells and immune cells (200 ×). A and B: Hematoxylin and eosin (H&E) and immunohistochemistry (IHC) picture of programmed cell death-ligand 1 (PD-L1) SP142 in tumor cells of one case; C and D: H&E and IHC picture of PD-L1 SP142 in immune cells of another case; E: Patients with high expression of PD-L1 (SP142) on tumor infiltrating lymphocytes tend to have less recurrence; F: Expression of PD-L1 (SP142) on tumor cells was not statistically significant. PD-L1: Programmed cell death-ligand 1; IHC: TILs: Tumor infiltrating lymphocytes; TCs: Tumor cells; PFS: Progression-free survival.
