Background & Aims: Serological markers of hepatocellular carcinoma (HCC) indicate its invasiveness. We aimed to investigate whether the prognostic impact of surgical resection (SR) and radiofrequency thermal ablation (RFA) on patients with single nodular HCC ⩽5 cm were different regarding positive conditions of the following three HCC markers: alpha-fetoprotein (AFP); lens culinaris agglutinin-reactive fraction of AFP; and des-γ-carboxy prothrombin.
