introduction: arsenic has been used as an effective medicine in the treatment of severe promyelocytic leukemia in recurrence and resistance cases toward atra. in this study, it has been used as induction and maintenance therapy after remission. method & material: we studied 31 patients diagnosed by apl. a rsenic was started at a dose of 0.15 mg/kg (daily) until patient’s bone marrow remission.(...

In acute myeloid leukaemia (AML) t(8;16)(p11;p13)/MYST3–CREBBP is a very rare abnormality. Previous small series suggested poor outcome. We report on 59 patients with t(8;16) within an international, collaborative study. Median age was 52 (range: 16–75) years. AML de novo in 58%, therapy-related (t-AML) 37% and secondary after myelodysplastic syndrome (s-AML) 5%. Cytogenetics revealed complex k...

Background Classification of cancer subtypes by means of microarray signatures is becoming increasingly difficult to ignore as a potential to transform pathological diagnosis nonetheless, measurement of Indicator genes in routine practice appears to be arduous. In a preceding published study, we utilized real-time PCR measurement of Indicator genes in acute lymphoid leukaemia (ALL) and acute m...

Introduction: GTPase regulator associated with focal adhesion kinase (GRAF) is a recently identified GTPase activating protein that has the tumor suppressor properties. However, the expression level of GRAF in leukemia had received less attention. The main purpose of this research was the evaluating of the expression level of GRAF in patients with acute myeloid leukemia (AML). Materials and met...

Background: Mutation in NPM1 gene has been reported to be the most common genetic mutation in de novo acute myeloid leukemia (AML). AML with NPM1 gene mutation usually presents with higher initial leukocyte and blast cell counts and negative CD34 expression. We aimed to investigate the difference of initial leukocyte counts, bone marrow blast cell counts and expression of CD34 among patients wi...

introduction: acute myeloid leukemia is a malignant transformation of hematopoietic tissue, bone marrow infiltration of undifferentiated cells known as blasts that interfere with the production of normal cells. vascular endothelial growth factor (vegf) is persistently secreted from myeloid cells and high levels can be detected in patients' serum. methods: twenty-one aml patients, who were chemo...

Background: Somatic mutations in the hotspot region of the DNA-methyltransferase 3A (DNMT3A) gene were recurrently identified in acute myeloid leukemia (AML). It is believed that DNMT3A mutations confer an adverse prognosis for AML patients. These lines of evidence support the need for a rapid and cost-efficient method for the detection of these mutations. The present study aimed to establish h...

Acute myelogenous leukemia (AML) is a hematological malignancy, which accounts for about 15-25% of childhood's leukemia. Genetic factor is one of the most important predisposing elements in childhood acute leukemia, especially AML. In this case report, a rare presentation of familial AML is presented in three monozygotic triplets. Two were 10 months old, and the other one was 16 months old at p...
