Carcinoembryonic antigen in hepatocellular cancer.

Serum carcinoembryonic antigen (CEA) concentrations were found to be raised in 28 of 72 black patients (39%) with hepatocellular cancer (HCC). The degree of elevation was slight or moderate, except in 3 patients in whom values greater than 20 ng/ml were recorded. No significant correlation could be demonstrated in individual patients between the serum CEA concentration and various tests of liver function. The mean CEA value in the patients with cirrhosis in the non-tumorous liver was slightly higher than that in those without cirrhosis, but the difference did not reach statistical significance. There was no correlation between serum CEA and alpha-foetoprotein (AFP) levels.
