[HL-A system antigen distribution in malignant neoplasm patients]

The distribution of transplantation HL-A antigens in 124 patients (cancer of the stomach, mammary glands, the large intestine, the lung, skeletal sarcoma) was studied in microlymphocyte toxic reaction. A comparison with the results of the analogous examination of healthy persons dwelling in Leningrad indicated certain differences in the frequency of encountering some antigens, and the absence of HLA-B18 antigen among patients. Most frequently (in 62%) an "incomplete set" of antigens was found in a group of patients, antigens typical for the whole locus (more frequently "B") being absent in 7.3%. In 6.4% "extra" (live or more) HL-A antigens were noted. The use of adaptive immunotherapy would significantly change antigenic spectrum of lymphocytes in patients.
