Screening for hepatocellular carcinoma in patients with Child's A cirrhosis: an 8-year prospective study by ultrasound and alphafetoprotein

One hundred and forty-seven patients with Child's A cirrhosis and no evidence of hepatocellular carcinoma were followed up in an 8-year prospective surveillance program with testing by ultrasound and alphafetoprotein every 6 months. Eighteen of 147 patients were HBsAg positive. Anti-hepatitis C virus antibodies were found in 103 out of 133 cases tested. Sixteen patients had a history of heavy drinking. Thirty hepatocellular carcinomas were detected during follow up. At the time of diagnosis, ultrasound detected focal lesions in all the patients whereas alphafetoprotein was below diagnostic levels. The hepatocellular carcinoma was single in 26 patients and multiple in four. The overall 8-year cumulative tumor-free rate was 69% (95% confidence interval=58–73). The yearly hepatocellular carcinoma incidence from 1985 to 1992 was respectively 2%, 1.5%, 2%, 3%, 5%, 4.8%, 7% and 10%. The initial value of AFP>50 ng/ml and 50 and
