ABSTRACT
Objective To analyze the expression of peripheral blood CD13+CD4+CD25hi regulatory T cells (Treg cells) in patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance. Methods The expression of peripheral blood CD13+CD4+CD25hi Treg cells in 58 newly diagnosed patients with DLBCL and 30 healthy adults was detected by flow cytometry, and the relationship between its expression and the clinical indicators were analyzed statistically. Results The levels of peripheral blood CD13+CD4+CD25hi Treg cells in newly diagnosed DLBCL and healthy adults were different, with statistically significant difference [(36.37 ±11.89) % vs. (9.03 ±2.10) %, t = 7.168, P 0.05). Conclusion The levels of peripheral blood CD13+CD4+CD25hi Treg cells are higher in DLBCL patients, which has a close relationship between the expression of CD13+CD4+CD25hi Treg cells and clinical stage and prognosis.
