Abstract

Among 326 consecutively resected cases of hepatocellular carcinoma (HCC), we studied clinicopathologic features of 13 cases (NBNC-HCC) negative for hepatitis B surface antigen (HBsAg), antibody to HBsAg (HBsAb), antibody to hepatitis B core antigen (HBcAb), hepatitis B envelope antigen (HBeAg), antibody to HBeAg (HBeAb), and antibody to hepatitis C virus (HCVAb). Forty-four HCC cases positive only for HBsAg (B-HCC) and 232 cases positive only for HCVAb (C-HCC) were studied as controls. Clinically, NBNC-HCC cases showed good liver function reserve. None of NBNC-HCC cases had periodic medical check ups and HCC was detected in 12 cases (92.3%) incidentally. Pathologically, the mean tumor diameter was significantly larger and the histologic grade was less differentiated in NBNC-HCC cases than in B-HCC and C-HCC cases. In the background liver, liver cirrhosis was associated in 15.4% of NBNC-HCC cases, 50.0% of B-HCC and 38.2% of C-HCC cases. The degree of inflammation and fibrosis was less in NBNC-HCC cases, and two cases (15.4%) had almost normal liver histology. In NBNC-HCC cases, synchronous and metachronous multicentric occurrence was not observed. In B-HCC cases, synchronous multicentric occurrence was found in 1 case (20.0%), but no metachronous multicentric occurrence. In C-HCC cases, synchronous and metachronous multicentric occurrence was found in 13 (43.3%) and 8 (30.8%) cases, respectively. However, the cumulative recurrence-free rate was not significantly different among the three groups. Accordingly, it was suggested that better prognosis could be expected in NBNC-HCC cases compared with B- and C-HCC cases, if the cancer could be detected in the early stage.
