Multiparametric tumor marker (CA 19-9, CEA, AFP, POA) analyses of pancreatic juices and sera in pancreatic diseases.
With respect to their diagnostic utility CA 19-9, CEA, AFP and POA were determined in pancreatic secretions and serum of patients suffering from pancreatic cancer (n = 76/55) or chronic pancreatitis (n = 79/45) and of controls (n = 81/42), respectively. While the determination of AFP and POA both in pancreatic secretions and serum does not permit a differential diagnosis, serum CEA (greater than 10 ng/ml) and CA 19-9 (greater than 50 U/ml) levels were indicative of pancreatic cancer in 30% and 83%, respectively, with a rate of false positive results of 5% and 8.5% confined to the chronic pancreatitis patients. A combination of tumor marker analyses, that is, serum CA 19-9 (greater than 50 U/ml) and pancreatic secretion CEA (greater than 70 ng/ml), proved to be positive in 92.9% of tumor patients with a maximum of 10.5% false positives. Likewise, values of serum CA 19-9 (greater than 50 U/ml) and serum CEA (greater than 10 ng/ml) were found in 85.8% of the pancreatic cancer patients with only 8.8% false positives, which were confined to the chronic pancreatitis patients. These results indicate the superiority of multiparametric tumor marker analyses for the diagnosis of pancreatic cancer, especially when including new monoclonal antibody defined tumor markers.
