Characteristics of hepatocellular carcinoma in hemodialysis patients in hepatitis B endemic area.

BACKGROUND/AIMS: Hepatocellular carcinoma is one of the most common malignancies in Taiwan, a hepatitis B endemic area. In this study, we aimed to evaluate the characteristics of hepatocellular carcinoma in patients receiving hemodialysis, as this patient group is at high risk for malignancy. METHODOLOGY: From October 1991 to September 1997, thirteen patients receiving hemodialysis and diagnosed with hepatocellular carcinoma were enrolled in this retrospective study. Patients' clinical course, laboratory data, image study and treatment were evaluated. RESULTS: Among these 13 patients, hepatitis B virus related in 6 and hepatitis C virus related in 7. There was no statistical significance in serum levels of asparate aminotransferase, alanine aminotransferase, bilirubin and alpha-fetoprotein between hepatitis B virus and hepatitis C virus related hepatocellular carcinoma. Hepatitis B virus related hepatocellular carcinoma had a shorter mean dialysis period (29.67 +/- 22.18 vs. 87.86 +/- 79.90 months, P = 0.25) and mean duration from beginning hemodialysis to diagnosis of hepatocellular carcinoma (17.16 +/- 26.94 vs. 76.08 +/- 65.69 months, P = 0.05), but there was no statistical significance. In the area of treatment, the survival curves of the treatment (hepatic resection and/or transcatheter arterial chemoembolization) group and supportive group were compared by log-rank test and there was no statistical significance for these two groups (P = 0.69). CONCLUSIONS: Both hepatitis B virus and hepatitis C virus are equally important for hepatocellular carcinoma in hemodialysis patients in hepatitis B endemic Taiwan. The acquisition of hepatitis B virus or hepatitis C virus might be not related to hemodialysis. Periodic screening with ultrasonography and serum alpha-fetoprotein is necessary among hemodialysis patients with evidence of hepatitis B virus or hepatitis C virus infection.
