CEA concentration and cytology in duodenal fluid collected during the Secretin-Pancreozymin test. Attempt at an early diagnosis of pancreatic carcinoma by means of simple procedure.
CEA concentration in juice collected during the Secretin-Pancreozymin test, and cytology were evaluated in order to establish whether they may be used as an aid in the diagnosis of pancreatic carcinoma before resorting to x-ray examinations. Thirty-three subjects were studied: 6 normal subjects, 12 with chronic pancreatitis, 3 after recovery from acute pancreatitis, 8 with gall-stones, 3 with carcinoma of the pancreas and 1 with cancer of the biliary tract. Three duodenal juice samples (at 30, 60 and 90 mins of hormonal infusion) were taken in each subject for CEA, cytology, bicarbonate and trypsin determinations. Although a significant statistical difference was noted between normal subjects and patients with carcinoma of the pancreas in the 30-min-juice sample, CEA concentration in the duodenal juice did not seem a reliable index in the diagnosis of pancreatic carcinoma. The information provided by cytology was also very scanty and sometimes misleading. The clinical picture and radiological investigation still remain the surest basis for the diagnosis of pancreatic cancer.
