Overview
"Surveillance is deemed cost-effective if the expected HCC risk exceeds 1.5% per year in patients with hepatitis C and 0.2% per year in patients with hepatitis B. Analysis of recent studies show that alpha-fetoprotein determination lacks adequate sensitivity and specificity for effective surveillance (and for diagnosis). Thus, surveillance has to be based on ultrasound examination. The recommended screening interval is 6 months" according to a clinical practice guideline by the American Association for the Study of Liver Diseases.[1]
"In a mixed-aetiology cohort, the most effective surveillance strategy is to screen each patient with AFP assay and ultrasound imaging on a 6-monthly basis" according to a systematic review by the NIHR Health Technology Assessment programme (UK).[2]
Evidence from trials
Regarding patients with hepatitis B, a meta-analysis by the Cochrane Collaboration concluded "".[3] In a randomized controlled trial included in the meta-analysis, the relative risk ratio of biannual alpha-fetoprotein and ultrasonography, as compared to no screening, for mortality from hepatocellular carcinoma was 0.6 and the relative risk reduction was 36.7%. In populations similar to those in this study which had a rate of risk as measured by the mortality from hepatocellular carcinoma of 0.13% without treatment, the number needed to treat is 2070.[4]
