ABSTRACT
The aim of this study was to detect the expressions of transforming growth factor (TGFβ(1)), tumor necrosis factor alpha (TNFα) and leukemia inhibitory factor (LIF) in newly diagnosed patients with acute myeloid leukemia (AML) and investigate the association between serum levels of various cytokines and clinical outcomes. The levels of TGFβ1, TNFα and LIF in patient's plasma were detected by enzyme-linked immunosorbent assays (ELISA) and were compared with healthy controls; bone marrow cell morphology, immunology, cytogenetics examinations (MIC) were performed meanwhile. The results showed that levels of TGFβ1, TNFα and LIF were elevated in AML patients as compared with the controls (13.08±9.77 ng/ml, 10.67±15.11 pg/ml, 4.23±4.73 pg/ml vs 8.23±3.12 ng/ml, 5.86±3.05 pg/ml, 2.78±1.22 pg/ml) (p all<0.05). The three cytokines and MIC examination analysis indicated that level of LIF was abnormally elevated in M5 patients (7.14±6.62 pg/ml); TNFα was abnormally elevated in M4 and M3 patients especially M4; TGFβ1 level in M6 and M2 patients was higher than others. TGFβ1 plasma concentration in low-risk group the lowest (10.45±4.73 ng/ml), and that in middle risk group was the highest (16.13±13.76 ng/ml) (p<0.05); the levels of other two kinds of factors in the chromosome karyotype groups showed no significant difference. It is concluded that TGFβ1, TNFα and LIF expressions showed increased level in the untreated patients with de novo AML, the TGFβ1 level among which is associated with the prognosis of patients.
