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

Figure 2 Representative hematoxylin and eosin images of the three immune subtypes (200 ×). A and B: Tumors with high infiltrating lymphocytes in the tumor center, invasive front and peritumor (Immune^high) subtype; C and D: Tumors other than immune^high and immune^low (Immune^mod) subtype; E and F: Tumors with low infiltrating lymphocytes in the tumor center, invasive front and peritumor (Immune^low) subtype; A, C, and E: Immune cells in tumor center; B, D, and F: Immune cells in the peritumor region.
