摘要
OBJECTIVE:To investigate the exprassion of WT1 gene in patients with adult acute myeloid leukemia (AML) and its clinical significance.
METHODS:Sixty-three newly diagnosed patients with acute myeloid leukemia were selected. Quantitative RT-PCR was used to detect the expression of WT1 gene in the 63 AML patients and 20 non-AML controls.
RESULTS:WT1 gene was highly expressed in AML patents and its expression in the low-risk group was significantly lower than that in middle-risk group and high-risk group (P<0.05), and no significant difference of WT1 gene expression between middle-risk and high-risk group was observed. In the patients of middle-risk and high-risk patients, the expression of WT1 gene in the remission group was significantly lower than that in the patients of non-remission after treatment (P<0.05). The non-remission patients after first treatment in middle-risk and high-risk group were treated with second induction therapy. After second induction therapy, the WT1 expression in remission patients was significantly decreased (P<0.05) in comparison with that in patients still in non-remission. There was a negative correlation between WT1 expression and the 2-year overall survival rate in the newly diagnosed middle and high-risk AML patients.
CONCLUSION:The detection of WT1 gene expression can help to divide AML patients into low-/middle-/high-risk groups and to evaluate therapeutic response and clinical prognosis in middle and high-risk AML patients.
