[Blood serum galactosyltransferase in oncologic diseases].

The paper is concerned with comparative analysis of the results of the determination of activity of galactosyl transferase, CEA and antigen CA-125 in the blood serum of 44 healthy persons, 70 cancer patients and 12 patients with benign diseases. It was shown that a radiometric test for galactosyl transferase in its diagnostic sensitivity was not inferior to CEA in stomach and ovarian tumors and exceeded the test for antigen CA-125 in ovarian cancer. In colon cancer the diagnostic accuracy of the tests for the activity of galactosyl transferase and CEA turned out to be identical. The most reliable diagnostic test in acute lymphoblastic leukemia in children was the test for galactosyl transferase activity.
