Clinical significance of prior hepatitis B virus infection in patients with hepatitis C virus-related hepatocellular carcinoma

BACKGROUND. The effect of prior hepatitis B virus (HBV) infection on the clinicopathologic findings for patients with hepatitis C virus (HCV) RNA and hepatocellular carcinoma (HCC) is still unclear. METHODS. Of 59 patients who underwent liver resection for HCV-related HCC (less than or equal to 2.0 cm in greatest dimension) without metastases between 1990 and 1997, 38 patients had anti-MB core antibody (anti-HBc) and did not have HE surface antigen in their sera (Group 1). Their clinicopathologic findings and outcomes after surgery were compared with those of the remaining 22 patients without anti-HBc (Group 2). RESULTS. The proportion of well-differentiated HCC was significantly lower in Group 1 than in Group 2 (P = 0.0214). The percentage of patients with cirrhosis was significantly lower in Group 1 than in Group 2 (P = 0.0228). The cumulative survival rate was significantly lower in Group 1 than in Group 2 (P = 0.0224). The risk ratio of anti-HBc for shorter survival time was 3.817. CONCLUSIONS. HCC more often developed before cirrhosis in patients with MCV RNA and anti-HBc than in patients positive for HCV RNA alone. Prior HBV infection was a risk factor for poor outcome after liver resection for patients infected with MCV. (C) 1999 American Cancer Society.
