T- and B-lymphocyte subpopulations following radiotherapy for invasive squamous cell carcinoma of the uterine cervix

R J Rand et al. Clin Exp Immunol. 1978 Jul.

Abstract

Lymphocyte subpopulations in patients with cervical carcinoma were studied before and after radiotherapy. T lymphocytes were recognized by their ability to form spontaneous rosettes with sheep erythrocytes (E rosettes). Two surface marker characteristics were used to detect B lymphocytes: receptors for activated complement responsible for erythrocyte--antibody--complement (EAC) rosette formation, and surface membrane immunoglobulin (SmIg), readily stainable by immunofluorescence. We have demonstrated a significant depression of total lymphocytes after radiotherapy which persists for more than 5 years. This reduction in lymphocytes is due to a loss of E rosette-forming T cells, SmIg-bearing B cells and null cells. Absolute numbers of EAC rosette-forming B cells are not altered by treatment, and there is a rise in this cell type when the results are expressed as percentages of the total lymphocyte count. The possible functional immunological significance of these changes is discussed.
