Protein Induced by Vitamin K Absence or antagonist-II (PIVKA-II) has been shown to be a useful marker for the diagnosis of hepatocellular carcinoma (HCC), especially when combined with alpha-fetoprotein (AFP), which is the most commonly used tumor marker for HCC. Overall, assays detecting both PIVKA-II and AFP have been shown to achieve a sensitivity and specificity 94% and 98.5%, respectively.

PIVKA-II is an abnormal form of prothrombin which is a blood coagulation protein synthesized in the liver. Usually it is converted to an active form by γ-carboxylation, however in patients with HCC or those with a vitamin K deficiency, this process is impaired and PIVKA-II is formed instead of prothrombin. Overall, PIVKA-II has shown to be an effective diagnostic biomarker in predicting the treatment response and clinical outcome of curative hepatic resection, chemotherapy, targeted therapy, radiotherapy and liver transplantation.
