Acute leukemia, the most common form of cancer in children, accounts for approximately 30% of all childhood malignancies, with acute lymphoblastic leukemia being five times more frequent than acute myeloid leukemia. Lineage switch is the term that has been used to describe the phenomenon of acute leukemias that meet the standard French-American-British system criteria for a particular lineage (...

Chromosome abnormalities that usually define high-risk acute lymphoblastic leukemia are the t(9;22)/ breakpoint cluster region protein-Abelson murine leukemia viral oncogene homolog 1, hypodiploid with < 44 chromosomes and 11q23/ myeloid/lymphoid leukemia gene rearrangements. The spectrum of acute lymphoblastic leukemia genetic abnormalities is nevertheless rapidly expanding. Therefore, newly d...

Chromatins prepared from leukemic lymphosarcoma cell(s), (LS), acute lymphoblastic leukemia cells, chronic lymphocytic leukemia cells and normal tissue culture lymphocytes (NC-37) were studied with respect to their chemical compositions, thermal denaturation profiles, and template activities. Acute lymphoblastic leukemia and LS chromatins had approximately 2 to 4 times the nonhistone protein an...

The runt-related transcription factor 1, RUNX1, is crucial in the development of myeloid and lymphoid cell lineages and has been reported to be mutated in myeloid malignancies in approximately 30% of cases. In this study, the mutational status of RUNX1 was investigated in 128 acute lymphoblastic leukemia patients. We detected a mutation rate of 18.3% (13 of 71) in patients with T-cell acute lym...

Detection of CD10, CD34 and their combined expression on Childhood Acute Lymphoblastic Leukemia and the association with clinical outcome in Indonesia 85 Detection of CD10, CD34 and their combined expression on Childhood Acute Lymphoblastic Leukemia and the association with clinical outcome in Indonesia CD10 and CD34 are surface markers that have been reported to have prognostic relevance in ch...

BACKGROUND Until recently, few molecular aberrations were recognized in acute lymphoblastic leukemia of T-cell origin; novel lesions have recently been identified and a certain degree of overlap between acute myeloid leukemia and T-cell acute lymphoblastic leukemia has been suggested. To identify novel T-cell acute lymphoblastic leukemia entities, gene expression profiling was performed and cli...

Chromatins prepared from leukemic lymphosarcoma cell(s), (LS), acute lymphoblastic leukemia cells, chronic lymphocytic leukemia cells and normal tissue culture lymphocytes (NC-37) were studied with respect to their chemical compositions, thermal denaturation profiles, and template activities. Acute lymphoblastic leukemia and LS chromatins had approximately 2 to 4 times the nonhistone protein an...

Acute myelofibrosis is characterized by pancytopenia of sudden onset, megakaryocytic hyperplasia, extensive bone marrow fibrosis, and the absence of organomegaly. Acute myelofibrosis in patients with acute lymphoblastic leukemia is extremely rare. We report a 4-year-old boy who was diagnosed as having acute massive myelofibrosis and acute lymphoblastic leukemia. Performing bone marrow aspiratio...

BACKGROUND The expression of HER2/neu in B-cell acute lymphoblastic leukemia has been reported in previous studies. OBJECTIVE The objective of this research was to study the expression of HER2/neu on the blasts of patients with acute leukemia from the Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran. METHODS From June 2015 to February 2016, a HER2/neu monoclonal antibody ...

Introduction: L-asparaginase and corticosteroids are widely used in the chemotherapy of acute lymphoblastic leukemia (ALL). This combination is known to cause several adverse effects one which hypertriglyceridemia. Although condition asymptomatic reversible it can lead serious complications.
