Abstract Carcinoembryonic antigen (CEA) activity was assayed in plasma and in pure pancreatic juice from eight patients with carcinoma of the pancreas, 28 patients with pancreatitis, and 13 controls with no demonstrable pancreatic disease. Juice specimens were obtained via direct transduodenal cannulation of the pancreatic duct. The mean pancreatic juice CEA activities in controls, pancreatitis, and pancreatic carcinoma were 8.1 ng/ml, 18.6 ng/ml, and 309 ng/ml, respectively. Pancreatic juice CEA activity in patients with cancer of that organ was significantly higher than in those with pancreatitis or in controls. None of the 32 subjects with both pancreatic juice CEA activity less than 30 ng/ml and plasma CEA less than 2.5 ng/ml had pancreatic cancer. Three of the four patients with CEA elevations in both fluids above these levels harbored this malignancy. These findings suggest that combined measurement of CEA activity in plasma and pancreatic juice may help in diagnosing pancreatic disease.
