performance of protein induced by vitamin k absence or antagonist-ii (pivka-ii) for hepatocellular carcinoma screening in chinese population
conclusions pivka-ii was as efficient as afp when used as a single marker for hcc screening and the combination of two biomarkers gave a better performance. results the sensitivity and specificity of pivka-ii were 74.6% and 67.8% at a cutoff of 40 mau/ml and 64.2% and 89.7% at a cutoff of 200 mau/ml. the sensitivity and specificity of afp were 76.7% and 65.0% at a cutoff of 20 ng/ml and 60.4% a...

Performance of Protein Induced by Vitamin K Absence or Antagonist-II (PIVKA-II) for Hepatocellular Carcinoma Screening in Chinese Population
BACKGROUND Alpha-fetoprotein (AFP) has long been used as an effective biomarker for hepatocellular carcinoma (HCC) screening; however, not all HCC patients can be detected with an elevated AFP level, especially in early HCC patients. Protein Induced by vitamin K absence or antagonist-II (PIVKA-II) is another serum biomarker linked to HCC; however, sensitivity and specificity remain controversia...
