Background: Minimal residual disease (MRD), which is characterized as leukemic cells at a level below morphologic detection, has been connected to the risk of relapse in acute myeloid leukemia. In 80–90% of acute myeloid leukemia (AML) patients, the Wilms tumor (WT1) gene is overexpressed at the mRNA level. In our prospective study, a total of 55 patients were enrolled in the study. Group I involved 40 AML patients and group II involved 15 patients healthy controls. WT1 gene expression was quantified using quantitative real-time PCR on bone marrow samples from AML patients at initial diagnosis and at day 28 after induction chemotherapy, and compared to 15 healthy controls in group II. Follow up of patients for prognosis evaluation was assessed. IBM SPSS software was used to capture and analyses the data. Results: At diagnosis, the mean WT1 transcript value in AML patients was substantially higher than the expression observed in control patient’s Bone marrow. There was no statistically relevant relationship between the onset of relapse and WT1 expression. Patients with WT1 overexpression at diagnosis had a shorter overall survival than patients with negative WT1 expression. Conclusions: Wilms tumor 1 gene expression was found to be significantly higher in AML patients than control cases, overall, our results confirmed the prognostic significance of WT1 overexpression in AML patients. Our findings support the application of MRD in AML patients based on WT1 overexpression.
