Elevation of carcinoembryonic antigen related to biliary malignancy in hepatolithiasis.
Bile duct neoplasms occur relatively often in patients with hepatolithiasis in Taiwan. In this study, 49 patients with a positive immunoperoxidase stain for carcinoembryonic antigen (CEA) in the bile duct glands were examined in relation to the concentration of CEA in serum and bile. The bile concentrations of CEA in 15 control patients, 16 patients with hepatolithiasis only, 7 with hepatolithiasis and bile duct carcinoma, and 11 with bile duct carcinoma only were 4.09 +/- 4.12, 70.49 +/- 81.62, 137.73 +/- 66.15, and 144.3 +/- 117.31 ng/ml (mean +/- SD), respectively. A positive CEA stain from the bile duct was seen in 13.33%, 81.23%, 85.71%, and 90.91% of each group, respectively. No strongly positive staining, (2+ or 3+) was found in the control group, but it was found frequently in the hepatolithiasis and bile duct carcinoma groups. The findings of this study therefore suggest the probability of a combined neoplasm in patients with hepatolithiasis if the CEA value is unusually elevated in the serum or bile.
