Comparison of prognosis of small hepatocellular carcinoma patients with hepatitis B virus infection versus hepatitis C virus infection

Abstract

To compare the prognosis of small hepatocellular carcinoma patients with hepatitis B virus infection versus hepatitis C virus infection. 413 patients receiving curative resections at Tianjin Cancer Hospital for small HCC (< or = 3 cm) from January 1997 to December 2003 were divided into four groups: HCV only (n = 75), HBV only (n = 251), HBV and HCV (n = 33), and neither HBV nor HCV (NBNC, n = 54). The preoperative status and postoperative recurrence were recorded. Survival analysis were used to assess the impact of HBV/HCV status on HCC recurrence. Patients with HCV were associated with older age, lower mean preoperative platelet counts and albumin levels, higher mean prothrombin time, alanine aminotransferase and total bilirubin levels. Tumors in patients with HCV are multinodular and less differentiated, and were associated with a higher incidence of vascular invasion and cirrhosis. During the follow-up, the HCV group showed a higher incidence of intrahepatic recurrence and multiple recurrent lesions than the other patients. HCC patients with HCV infection tended to be older, and were characterized by more severe cirrhosis and higher incidence of tumor multinodular. The statistically significant determinants of reoccurrence in patients with small HCC were HCV infection, presence of vascular invasion and multiple tumors.
