ELISA
Protein Induced by Vitamin K Absence or Antagonist-II (PIVKA-II), also known as des-?-carboxy prothrombin (DCP), is an abnormal form of prothrombin produced primarily by liver tissues under conditions of vitamin K deficiency or antagonism. This immature prothrombin variant lacks sufficient coagulation activity and is prominently overexpressed in hepatocellular carcinoma (HCC) cells, serving as a crucial biomarker for screening and diagnosing HCC. PIVKA-II also appears in some cases of gastric cancer, albeit less frequently. Elevated serum levels of PIVKA-II are not exclusive to malignancies; they can also be seen in non-HCC conditions, which necessitates differential diagnostic strategies. The utility of PIVKA-II is further underscored by its ability to predict extrahepatic metastases in early HCC, supporting its role in comprehensive patient evaluation and monitoring.
