title: [Hepatocellular carcinogenesis and prognosis of elderly patients with chronic hepatitis type C].
abstract: Among 457 elderly patients of 65 years or older with chronic hepatitis or cirrhosis caused by hepatitis C virus, 117 patients underwent interferon therapy for the elimination of hepatitis C virus. A total of 87 patients could be analyzed for the interferon effect, since the remaining 20 patients had still been receiving or just finished the therapy. Thirty-six patients(41.4%) achieved complete elimination of HCV-RNA with interferon therapy. Although those patients with a milder hepatitis stage and better virological condition(low viral concentration or group 2 subtype) were preferentially enrolled in the therapy, 13 patients(11.1%) discontinued the administration with varied side effects: severe general malaise in 6 patients, depression in 3, pneumonia/pneumonitis in 2, and retinopathy in 2. Crude hepatocellular carcinogenesis rates in the subgroup of F1 + F2 and the subgroup of F3 + F4 were 1.8%, 21.2% at the end of 5th year, and 14.3% and 53.7% at the tenth year, respectively.
