Alpha-fetoprotein Reactive to Pisum Sativum Agglutinin in Liver Tumor Tissues and Sera from Patients with Primary Liver Cancer / 第二军医大学学报

ABSTRACT

Alpha-fetoprotein reactive to pisum sativum agglutinin (AFP-R-P) in liver tumor tissues, surrounding noncancerous tissues and peripheral blood from 25 cases of primary liver cancer were measured. Their medium and standard deviation were 41 ?26%, 30?27% and 36?25%, respectively. AFP-R-P levels were lower in the tumors with a diameter of less than 3cm, intact capsule, no invasion of surrounding liver tissues and no tumor thrombus. The patients with lower AFP-R-P levels had a longer survival. The results indicate that AFP-R-P is secreted mainly by tumor cells possessing more malignant behaviour, diffused directly in surrounding liver tissues and entered into peripheral blood, resulting in elevated serum AFP-R-P.
