[Serum tissue polypeptide antigen in the differential diagnosis of chronic pancreatitis and exocrine pancreatic tumors. Preliminary results].

The authors give the preliminary results about the determination of the tissue polypeptide antigen (TPA) in chronic pancreatitis and pancreas exocrine tumors, indicating that although it can make a differential diagnosis between the two diseases, it is of no practical value because of the frequent increase of TPA in several non tumoral processes that may or may not accompany pancreatic tumors.
