Lower incidence of hepatic failure than hepatocellular carcinoma in Japanese patients with chronic hepatitis C.

Background: Previous studies have shown that the development of hepatic failure was found more frequently than that of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C in the United States and European countries. We investigated the status in Japan in a retrospective cohort study. Methods: The incidences of HCC and hepatic failure were accessed in 459 patients with biopsy-proven C-viral chronic liver disease with a mean follow-up period of 8.9 +/- 3.2 years and the cause of death was also analyzed in the cohort. Results: HCC developed in 63 patients, 46 of 355 interferon (IFN)-treated and 17 of 104 untreated patients. In contrast, the development of hepatic failure was found in 18 patients, 12 of 355 IFN-treated and six of 104 untreated patients. HCC developed in four of 116 with sustained virological response (SVR), and hepatic failure developed in one of them. Thirty-two of 63 patients developing HCC and eight of 18 patients developing hepatic failure died. Conclusions: Development of hepatic failure was less frequent than that of HCC in Japan. It is important for a favorable prognosis of patients with C viral chronic liver disease to achieve a higher SVR and thus inhibit the development of HCC in Japan.
