title: Application of des-gamma-carboxy prothrombin as a complementary tumor marker with alpha-fetoprotein in the diagnosis of hepatocellular carcinoma.
abstract: By means of staphylocoagulase, plasma des-gamma-carboxy prothrombin (DCP) was measured in 255 subjects. Of these, 59 were healthy controls, 100 had primary hepatocellular carcinoma (PHC), 33 had cirrhosis of the liver, 16 had hepatitis, 11 had metastatic carcinoma of the liver (MCL), and 36 subjects had previously been treated with anti-vitamin K drugs. The mean plasma DCP level in the healthy subjects was 3.02 VGH U/l. Of PHC patients 80% had DCP levels greater than 6 VGH U/l, which we regarded as probably abnormal. None of the patients with benign liver diseases (cirrhosis of liver or hepatitis) had DCP greater than 10 VGH U/l. Of the patients with MCL 54.54% had DCP greater than 6 VGH U/l. In our study DCP was found to be as sensitive a tumor marker as alpha-fetoprotein (AFP) in the diagnosis of PHC and was better in distinguishing PHC from benign liver disease. Of PHC patients 92% had at least one of the two tumor markers. Simultaneous determination of DCP and AFP should be applied in mass survey programs for detecting PHC, especially in countries with a high prevalence of hepatitis B virus infection.
