A 44 year old man complaints of abdominal distention and nausea since few months. USG of abdomen shows a growth on right lobe of the liver. Tumor marker study shows the evidence of primary hepatocellular carcinoma. All of the following tumor markers will be raised in this patient, EXCEPT:

AFP is a serum tumor marker for HCC; however, it is only increased in approximately one-half of patients. The lens culinaris agglutinin-reactive fraction of AFP (AFP-L3) assay is thought to be more specific. The other widely used assay is that for des-gamma-carboxy prothrombin (DCP), a protein induced by vitamin K absence (PIVKA-2). Many other assays have been developed, such as glypican-3, but none have greater aggregate sensitivity and specificity. Ref: Carr B.I. (2012). Chapter 92. Tumors of the Liver and Biliary Tree.
