Hepatocellular carcinoma development in sustained viral responders to interferon therapy in patients with chronic hepatitis C.
The incidence of hepatocellular carcinoma (HCC) tends to decrease in sustained responders (SR) to interferon (IFN) therapy for chronic hepatitis C rather than in non-responders (NR). However, some SR develop HCC and their details and prognosis are not well-known, so we investigated such cases. Among 462 patients who underwent IFN therapy and were available for follow-up, 142 patients (30.7%) were SR and six of these (4.2%) developed HCCs. The interval between interferon therapy and diagnosis of HCC was 32-99 months (average 59.2 months). Five of the six cases were single HCCs sized 20-125 mm. The remainder was multiple HCCs. After initial treatment, five patients (83.3%) relapsed and three patients (60%) died due to the HCC. The interval between initial treatment and recurrence was 2-14 months (average 5.8 months). Among the three fatal cases, the interval between initial treatment and their death was 11-66 months (average 29.3 months). Though the prognosis of the one patient who did not relapse after initial treatment was good, the other five patients relapsed and three of them died due to the HCC. These results suggest that the prognosis of sustained responders who develop HCC after IFN therapy is not necessarily good, so close follow-up remains necessary, despite their response to IFN therapy.
