    Abstract:
    The pathology and prognosis of hepatitis B surface antigen (HBsAg)-positive hepatocellular carcinoma (HCC) and hepatitis C virus antibody (HCVAb)-positive HCC is well documented. However, patients with HBsAg-negative/hepatitis B core antibody (HBcAb)-positive HCC are included with non-B non-C disease and have been characterized independently. A series of 125 patients who had undergone hepatectomy for HCC were divided into three groups and compared. The HBsAg group comprised 25 HBsAg-positive patients, the HCV group comprised 70 HCVAb-positive patients, and the HBcAb group comprised 22 HBcAb-positive/HBsAg-negative patients. Eight patients of negative virus markers were excluded in this study. Tumors were larger in the HBcAb group (6.2 cm) than in the HBsAg (4.4 cm) and HCV (3.7 cm) groups. Disease-free 1-, 3-, and 5-year survival rates were, respectively, 75.0%, 57.1%, and 57.1% in the HBcAb group; 60.9%, 41.8%, and 41.8% in the HBsAg group; and 88.0%, 54.0%, and 37.8% in the HCV group. HBcAb-positive HCC patients had larger tumors, but their prognosis was relatively good. Although HBsAg and HCVAb are used for conventional screening of patients with hepatic disorders, we believe that screening is also necessary in patients with positive HBcAb titers for early detection of HCC.
