[Immunophenotyping in the differential diagnosis of malignant non-hodgkin's lymphomas]

Non-Hodgkin's malignant lymphoma was diagnosed in 66 patients by immunophenotype technique using a batch of 13 Russian-isolated monoclonal antibodies which help identify antigens of T- and B-lymphocyte surface membranes. Polyclonal light chains of immunoglobulins and T- and B-cell antigens were identified in the course of histological examination of biopsy material sampled from hyperplasia lymphoid tissue. B-cell lymphomas revealed monoclonal light chains of immunoglobulins and positive B-cell antigens. T-cell tumors had mostly T-cell antigens and no light chains of immunoglobulins. Neither common leukocyte antigen, nor panT- or panB-cell antigens were found in 7 cases of cancer metastasis to lymph nodes.
