AFP and neoplasm: Multivariate analysis revealed that high serum bilirubin (>3 mg dl−1), the presence of uncontrollable ascites, and a high platelet count (>8 × 104 mm−3), so-called background liver factors, as well as multiple tumours, large tumours (>3 cm), high alpha-fetoprotein (>400 ng ml−1), and the presence of portal vein thrombus, so-called tumour factors, were factors of poor prognosis.
