USE OF TUMOR-MARKERS IN DIFFERENTIAL-DIAG NOSIS OF 3-DIMENSIONAL STRUCTURES IN THE LIVER

The radioimmunological method was used to determine the content of tum or markers APP, REA, CA 19-9, and CA 72-4 in 53 patients with nonmalig nant three-dimentional structures in the liver (hemangioma, nonparasit ic cysts, alveococcosis, hydatid cycts), in 9 patients with primary ca rcinoma of the liver, and in 24 healthy individuals. The significance of APP determination and complex study of tumor markers in the recogni tion and differential diagnosis of benign and malignant structures in the liver is shown. It allowed the percentage of disparity between the laboratory and the verified diagnosis to be reduced to 4.8%.
