Abstract:

Objective To investigate the correlation between the percentage of CD39+CD4+CD25+ T cells in lymphocytes and prognosis in patients with acute myeloid leukemia(AML).Methods A total of 157 patients with AML(AML group) were enrolled and classified into 5 subtype groups (AML-M1,AML-M2,AML-M3,AML-M4 and AML-M5),and 41 healthy subjects were enrolled as healthy control group. By flow cytometry,the percentages of CD39+CD4+CD25+ T cells and CD4+CD25+ T cells in lymphocytes were determined. AML group was sub-classified into low-,middle- and high-level groups according to the percentage of CD39+CD4+CD25+ T cells or CD4+CD25+ T cells in lymphocytes.Results Compared to healthy control group,the percentages of CD39+CD4+CD25+ T cells in lymphocytes were higher in AML group and its 5 subtype groups(P<0.05). There was no statistical significance for the percentages of CD4+CD25+ T cells between AML and healthy control groups(P>0.05),but the percentage of AML-M1 subtype group was lower than that in healthy control group(P<0.05),and the percentage of AML-M2 subtype group was higher than that in healthy control group(P<0.05).The proportion of extramedullary infiltration and the positive rates of CD34 and CD7 of blast cells in low-,middle- and high-level groups according to the percentages of CD39+CD4+CD25+ T cells in lymphocytes were gradually increased(P<0.05),but there was no statistical significance among low-,middle- and high-level groups according to the percentages of CD4+CD25+ T cells in lymphocytes(P>0.05). Patients with high- and middle-level CD39+CD4+CD25+ T cell percentages had a shorter time to next treatment (TTT) compared with patients with low-level CD39+CD4+CD25+ T cell percentage(P<0.05). However,patients with low-,middle- and high-level CD4+CD25+ T cell percentages had no statistical significance for TTT(P>0.05).Conclusions The increasing percentage of CD39+CD4+CD25+ T cells in lymphocytes is correlated with poor prognosis,and CD39 may be a marker for the disease development of AML.
