[Clinical evaluation of CA 19-9, TPA, IAP and 5'-NPD-V as tumor markers of hepatocellular, bile duct and pancreas carcinoma]

Abstract

The serum level of CA 19-9 elevated exponentially in gastrointestinal carcinoma and the specificity of CA 19-9 was extraordinarily high. The sensitivity of CA 19-9 to pancreas, bile duct, hepatocellular and metastatic liver carcinoma was 75%, 79%, 22%, and 82% each. TPA seems to be useful as a screening tumor maker of gastrointestinal carcinoma, because the sensitivity was very high (84%) in every gastrointestinal carcinoma. IAP increased in pancreas and bile duct carcinoma and reflected immunological status of tumor bearing host. 5'-NPD-V was useful tumor marker not only of hepatocellular carcinoma but also pancreas and bile duct carcinoma.
