BACKGROUND Studies from various countries have found an increasing incidence of childhood leukemia in recent decades. To characterize time trends in the age- and sex-specific incidence of childhood acute leukemia during the last 20 years in the Nordic countries, we analyzed a large set of population-based data from the Nordic Society of Paediatric Haematology and Oncology (NOPHO) in their acute...

abstract background leukemia is one of the most common tumors in children and it is divided up into two main groups acute and chronic leukemia. the acute leukemia is more prevalent than chronic in children. generally acute type is included acute lymphoid leukemia (all) and acute myeloid leukemia (aml). in this study, patients with leukemia who were admitted in talghani hospital of gorgan were e...

Isochromosome 17q is a relatively common karyotypic abnormality in medulloblastoma, gastric, bladder, and breast cancers. In myeloid disorders, it is observed during disease progression and evolution to acute myeloid leukemia in Philadelphia-positive chronic myeloid leukemia. It has been reported in rare cases of myelodysplastic syndrome, with an incidence of 0.4-1.57%. Two new agents have...

OBJECTIVE The aim of this study was to determine the efficiency of the high throughput FISH analysis (HTFA) method for detecting genetic alterations in hematological malignancies, which is a new bacterial artificial chromosome array-based approach. MATERIALS AND METHODS We performed a HTFA study of bone marrow aspiration and peripheral blood samples of 77 cases (n=19 myelodysplastic syndrome,...

MicroRNA-34b down-regulation in acute myeloid leukemia was previously shown to induce CREB overexpression, thereby causing leukemia proliferation in vitro and in vivo. The role of microRNA-34b and CREB in patients with myeloid malignancies has never been evaluated. We examined microRNA-34b expression and the methylation status of its promoter in cells from patients diagnosed with myeloid malign...

Cutaneous presentation revealing acute myeloid leukemia (AML) is rare, and the prognosis poor. We report a case of an 11-month-old male who presented with cutaneous lesions present as diffuse purplish papulo-nodular lesions, M5 leukemia. Skin biopsy immunohistochemical examination, combined routine blood analysis bone marrow contributed to early diagnosis. However, despite intensive chemotherap...

Objective: Lymphoid enhancer-binding factor-1 (LEF1) is one of the key regulators lymphocyte proliferation and its aberrant expression a prognostic factor for lymphoid or myeloid malignancies. In this study, we focused on LEF1 isoforms in several hematological malignancies found tissue-specific differential full-length (FL)-LEF1 gene tumor suppressor (∆LEF1) variant. Material Method: Fifty-thre...
