title: Interferon alpha inhibits intrahepatic recurrence in hepatocellular carcinoma with chronic hepatitis C: a pilot study.
abstract: The aim of the present study is to evaluate whether interferon alpha (IFNalpha) therapy can inhibit intrahepatic recurrence after the curative treatment of small HCC with underlying chronic hepatitis C. Forty patients were enrolled in this study. They had solitary, small HCC</=3 cm in diameter, underlying chronic hepatitis C, and were </=70 years old. Of the patients, 18 were treated with IFNalpha for 6 months after the treatment of HCC, and 22 patients who did not receive IFNalpha therapy were used as controls. Six (33%) patients in the IFN group showed sustained response. The incidence of local recurrence was not different in the IFN and non-IFN groups (6 vs. 9%). The cumulative incidences of distant recurrence in the non-IFN and IFN groups were 9 and 6% at 1 year, 27 and 11% at 2 years, 63 and 18% at 3 years, 76 and 28% at 4 years, and 82 and 28% at 5 years; they were significantly different (P<0.01). Six (27%) patients in the non-IFN group died from the progression of HCC, but all IFN-treated patients were alive (P<0.05). The pilot study demonstrates that IFNalpha therapy after the curative treatment of small HCC can inhibit intrahepatic recurrence in the remnant liver and improve the prognosis of hepatitis C virus-related HCC.
