Analysis of Treg in bone marrow of patients with multiple myeloma and its correlation with clinical prog-nostic factors / 实用肿瘤学杂志

ABSTRACT

Objective To evaluate immune function of patients with multiple myeloma ( MM) by detect the changes of the Treg cells in bone marrow of patients with MM .Methods Treg cells in peripheral blood and bone marrow of 45 patients with MM and 15 healthy controls were measured by flow cytometry .Results The per-centage of Treg cells in peripheral blood of MM was higher than that in healthy person ;The percentage of Treg cells in MM bone marrow was lower than that in healthy person ,and the extent was positively correlated with the level of β2-MG and ISS(P<0.05).Conclusion MM Patients display an abnormal level of CD 4 +CD25 +Treg cells,which may be an important mechanism of MM immune deficiency .
