  6. CA 19-9 • CA 19-9 antigen is a sialylated oligosaccharide that is most commonly found on circulating mucins in cancer patients. It can be elevated in acute or chronic biliary disease. • Patients with pancreatic carcinoma, 75-85% have elevated CA 19-9 levels. CA 19-9 value of greater than 100 U/mL is highly specific for malignancy, usually pancreatic.

  7. CEA • Carcinoembryonic antigen (CEA) is a high–molecular weight glycoprotein found normally in fetal tissues. It has commonly been used as a tumor marker in other gastrointestinal malignancies. • The reference range is less than or equal to 2.5 mg/mL. • Only 40-45% of patients with pancreatic carcinoma have elevated CEA levels.
