Molecules governing cellular interactions have been suggested to be involved in the spurious elevation of alpha 1-fetoprotein (AFP) in non-neoplastic liver disease. To explore this controversial issue, we measured AFP, circulating intercellular adhesion molecule 1 (cICAM-1), and common liver function tests in 111 patients (71 male, 40 female). Eighty-four patients had non-neoplastic chronic liver disease and 27 had hepatocellular carcinoma. The concentration of cICAM-1 was determined immunoenzymatically. In patients with non-neoplastic chronic liver disease, univariate analysis demonstrated a significant correlation between AFP and cholinesterase (R = -0.397, P < 0.001), aspartate aminotransferase (R = 0.421, P < 0.001), bilirubin (R = 0.231, P < 0.05) and cICAM-1 (R = 0.430, P < 0.001). Multivariate analysis among these variables and AFP indicated cICAM-1 to be the strongest independent predictor of AFP. We conclude that cICAM-1 compares favourably with liver function tests in predicting non-specific AFP variations in non-neoplastic chronic liver disease, suggesting a link between targeting of the inflammatory damage to the hepatocyte and development of neoplasia.

Abstract

Molecules governing cellular interactions have been suggested to be involved in the spurious elevation of alpha 1-fetoprotein (AFP) in non-neoplastic liver disease. To explore this controversial issue, we measured AFP, circulating intercellular adhesion molecule 1 (cICAM-1), and common liver function tests in 111 patients (71 male, 40 female). Eighty-four patients had non-neoplastic chronic liver disease and 27 had hepatocellular carcinoma. The concentration of cICAM-1 was determined immunoenzymatically. In patients with non-neoplastic chronic liver disease, univariate analysis demonstrated a significant correlation between AFP and cholinesterase (R = -0.397, P < 0.001), aspartate aminotransferase (R = 0.421, P < 0.001), bilirubin (R = 0.231, P < 0.05) and cICAM-1 (R = 0.430, P < 0.001). Multivariate analysis among these variables and AFP indicated cICAM-1 to be the strongest independent predictor of AFP. We conclude that cICAM-1 compares favourably with liver function tests in predicting non-specific AFP variations in non-neoplastic chronic liver disease, suggesting a link between targeting of the inflammatory damage to the hepatocyte and development of neoplasia.
