title: Tumor-associated trypsin inhibitor in pancreatic diseases.
abstract: We have evaluated tumor-associated trypsin inhibitor (TATI) as a marker for pancreatic and hepatic cancer. Of the patients studied 52 had pancreatic cancer, 30 primary liver cancer, 32 chronic pancreatitis, 25 biliary tract inflammatory disease, and 28 liver cirrhosis. A considerable number of falsely elevated values were observed in benign biliary diseases and in chronic relapsing pancreatitis. In pancreatic cancer the sensitivity of TATI was 63% while that of CEA was 40% and of CA19-9 77%. TATI is a marker of pancreatic disease but it does not differentiate between pancreatitis and pancreatic cancer. In liver cancer TATI and AFP has similar sensitivity and specificity.
