Objective
To investigate the effect of gemcitabine plus cisplatin chemotherapy on the percentage of CD4+CD25+FOXP3+ and CD8+CD28 regulatory T cells (Tregs) in the peripheral blood of patients with nonsmall-cell lung cancer (NSCLC).
Methods
Peripheral blood was taken from patients with NCSLC (before and after chemotherapy) and control subjects with nonmalignant disease. The percentages of CD4+CD25+FOXP3+ and CD8+CD28 Tregs were analysed using flow cytometry.
Results
Patients (n = 40) had significantly higher CD4+CD25+FOXP3+ and CD8+CD28 percentages than control subjects (n = 24). CD4+CD25+FOXP3+ and CD8+CD28 percentages increased with tumour progression, fell significantly after chemotherapy, but remained significantly higher than control values.
Conclusions
CD4+CD25+FOXP3+ and CD8+CD28 Treg percentages were higher in patients with NSCLC than control subjects, and increased in line with tumour progression. Percentages of CD4+CD25+FOXP3+ and CD8+CD28 Tregs were significantly reduced following gemcitabine plus cisplatin chemotherapy.
