Materials and Methods: Thirty-four women were treated either with RT-alone (n=14) or RT-CHT (n=20). Peripheral lymphocytes were collected before, immediately after and 6, 12 and 24 weeks after completion of treatment. Flow cytometric analysis included total T-cells, T-helper-cells, T-suppressor-cells, T-cytotoxic-cells, NK-cells, B-cells and the CD4+/CD8+ratio. Results: Twenty-four weeks after treatment, B-cells had recovered to pretreatment levels whereas total lymphocyte counts, T-helper and T-cytotoxic-cells were still significantly reduced in both groups. In contrast, T-suppressor-cells and NK-cells had recovered to pretreatment levels only in patients who received RT-alone and were still significantly reduced in patients who received RT-CHT. Conclusion: RT-alone and RT-CHT induce a significant and prolonged suppression of all lymphocyte subpopulations. RT-CHT, but not RT-alone, causes a prolonged suppression of NK-cells and T-suppressor cells. Copyright© 2005 International Institute of Anticancer Research (Dr. John G.
