Efficacy of transcatheter arterial embolization plus targeted chemotherapy for advanced hepatocellular carcinoma: A case report and literature review

Figure 2 Histopathological examination of liver tissue. A: Hematoxylin and eosin (HE); B: Cluster of differentiation 34 (CD34); C: Cytokeratin 7 (CK7); D: Glypican-3 (Gly-3); E: Glutamine synthetase (GS); F: Hepatocyte-1 (Hep-1); G: Heat Shock Protein 70 (HSP70); H: Ki-67 (Ki67). Liver tumor cells are arranged in trabeculae of at least two cell layers thick. The trabeculae are separated by hepatic sinusoids lined with a single layer of endothelial cells, and no bile duct structures are observed. Immunohistochemical staining: Ki-67 (+, < 5%); HSP70 (weakly positive); Hep-1 (+); GS (+); Gly-3 (equivocal ±); CD34 (vascular positive); CK7 (focally positive).
