T-cell subsets in peripheral blood of patients with newly diagnosed and posttreatment Hodgkin's and non-Hodgkin's lymphomas. Analysis by monoclonal antibody staining and flow cytometry.
T-cell subsets in the peripheral blood of patients with Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NHLs) were determined using anti T-cell monoclonal antibodies and flow cytometry. Forty HD patients and 30 NHL patients were evaluated; 76 normal blood donors served as controls. Newly diagnosed (untreated) HD and NHL patients had relatively normal values for percentages of total T-cells, helper cells and suppressor cells; their helper/suppressor ratios were also normal. The total lymphocyte count was normal for pretreatment HD, but lower than normal for NHL. Following treatment, both HD and NHL patients showed significantly decreased helper/suppressor ratios, caused by a significant decrease in the percentage of helper cells in HD patients and a significant increase in the percentage of suppressor cells in the small number of NHL patients studied. A small number of NHL patients, followed without specific treatment (passive follow-up), had relatively normal values for percentages of helper and suppressor cells and total T-cells. For both groups of patients off treatment, it is concluded that the lower helper/suppressor ratios are due to the prolonged effects of treatment (predominantly irradiation).
