Background and Aims: Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are the most common primary hepatic malignancies. Immunohistological differentiation of both tumors is pivotal for treatment and prognosis. Recently, alpha V beta 6 integrin (avb6) was found strongly upregulated in experimental biliary fibrosis and in patients with cholestatic liver disease, but its expression in primary liver cells and diagnostic applicability to distinguish primary cancers is unknown. Methods: 77 HCC and 73 CC paraffin-embedded tissues from patients who underwent partial hepatectomy were collected and immunostained…
