Clinical relevance of increased serum preneoplastic antigen in hepatitis C-related hepatocellular carcinoma

Figure 2 Receiver-operating characteristic analyses of preneoplastic antigen, α-fetoprotein and des-γ-carboxy-prothrombin in hepatitis C virus-related hepatocellular carcinoma. The sensitivity and specificity of markers were determined to discriminate hepatocellular carcinoma patients from hepatitis patients and cirrhosis patients. A: Hepatitis patients; B: Hepatitis and cirrhosis patients. The receiver–operating characteristic curve was obtained by plotting the sensitivity on the Y-axis against 1-specificity on the X-axis, and the area under the receiver–operating characteristic curve was calculated. PNA: Preneoplastic antigen; AFP: α-Fetoprotein; DCP: Des-γ-carboxy-prothrombin.
