Abstract

Background/aims: The present study was undertaken to compare the clinical characteristics, availability of initial treatment options and prognostic features of patients with hepatocellular carcinoma in relation to hepatitis B or C viral infection.

Methodology: Six hundred and ninety-two patients with hepatocellular carcinoma treated during the 12-year-period from Jan 1989 to Dec 2000 were categorized into three groups as follows: 1) 59 were classified as the HBV group: positive for hepatitis B surface antigen (HBsAg) and negative for antibody to hepatitis C (HCVAb), 2) 594 were placed in the HCV group: negative for HBsAg and positive for HCVAb, and 3) 39 were put into the Non-B, Non-C (NBNC) group: negative for both HBsAg and HCVAb. The age distribution, gender ratio, serum alpha-fetoprotein level, the presence of underlying cirrhosis, tumor size, the number of hepatocellular carcinoma tumors at the initial detection, the types of follow-up until the initial detection of hepatocellular carcinoma, the initial treatments chosen, and the survival were analyzed and compared among the three groups.

Results: Regarding age, the HBV group showed a younger age (56.3 +/- 12.2 years old) than the other two groups (the HCV group: 66.3 +/- 8.3, the NBNC group: 67.9 +/- 8.5 years old), however, no difference was observed in the male-to-female ratio of the three groups. The serum alpha-fetoprotein level, the prevalence of hepatocellular carcinoma measuring more than 3 cm in diameter, non-solitary hepatocellular carcinoma and portal thrombosis were strongly demonstrated at the initial detection in the HBV group, which was most likely due to the poor follow-up until detection. Consequently, the 1-, 3-, 5- and 7-year survivals of the patients in the HBV group were 40.4, 25.1, 18.8 and 5.2%, and were significantly shorter than both the HCV group which were 72.6, 44.9, 25.0 and 10.0%, and the NBNC group which were 71.2, 41.4, 31.1 and 31.1%, respectively. As for the NBNC group, in spite of the lack of a careful follow-up a longer survival was observed probably because they had a better preserved liver condition.

Conclusions: Regarding the hepatocellular carcinoma patients, those infected with HBV presented at the advanced stage due to the lack of a careful follow-up, thus resulting in a shorter survival. As a result, hepatocellular carcinoma patients infected with HBV need to be strictly followed up.
