Diagnostic value of gamma-glutamyltransferase/aspartate aminotransferase ratio, protein induced by vitamin K absence or antagonist II, and alpha-fetoprotein in hepatitis B virus-related hepatocellular carcinoma

Figure 1 Analysis of gamma-glutamyltransferase to aspartate aminotransferase ratio. A-C: Correlations of protein induced by vitamin K absence or antagonist II (PIVKA-II), alpha-fetoprotein (AFP), and the ratio of gamma-glutamyltransferase and aspartate aminotransferase (γ-GT/AST) with tumour size; D-F: Comparison of serum levels of PIVKA-II, AFP, and γ-GT/AST between early-stage hepatocellular carcinoma (HCC) patients, advanced HCC patients, and chronic hepatitis B patients. PIVKA-II: Protein induced by vitamin K absence or antagonist II; AFP: Alpha-fetoprotein; γ-GT/AST: The ratio of gamma-glutamyltransferase to aspartate aminotransferase; HCC: Hepatocellular carcinoma; CHB: Chronic hepatitis B.
