Mutations in the isocitrate dehydrogenase gene (IDH1) were recently described in patients with acute myeloid leukemia (AML). To investigate their prognostic significance we determined IDH1 status in 1333 young adult patients, excluding acute promyelocytic leukemia, treated in the United Kingdom MRC AML10 and 12 trials. A mutation was detected in 107 patients (8%). Most IDH1(+) patients (91%) ha...
BACKGROUND MicroRNAs are regulators of gene expression, which act mainly by decreasing mRNA levels of their multiple targets. Deregulated microRNA expression has been shown for acute myeloid leukemia, a disease also characterized by altered gene expression associated with distinct genomic aberrations such as nucleophosmin (NPM1) mutations. To shed further light on the role of deregulated microR...
AML with translocation t(3;5) belongs to the “AML with myelodysplasia-related changes” defined in the 2008 WHO classification. The incidence of this balanced abnormality is less than 0.5% of AML. The identified breakpoints occur at 3q25.1 on chromosome 3 and at 5q34 on chromosome 5, where the nucleolar phosphoprotein nucleophosmin 1 (NPM1) is located. At locus 3q25.1, Yoneda-Kato et al. identif...
Different molecular aberrations can be discriminated into certain prognostic subgroups in cytogenetically normal acute myeloid leukemia (CN-AML) patients but their impact on allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains controversial and studies from Asian populations are lacking. Forty-two adult non-M3 AML patients receiving allo-HSCT from 2002 to 2009 in southern Taiw...
We present a short case series of elderly patients with NK-AML and isolated NPM1 mutation who were treated with intensive chemotherapy, achieving significant CRs multiple times on reinduction, even with a single course.We hope to highlight the NPM1 as a molecular marker in elderly for consideration of aggressive treatment, even if abridged, as this subset may achieve a durable, good quality res...
OBJECTIVE To study the frequency of mutations that may lead to a good or bad prognosis, as well as their relation with the karyotype and immunophenotype in patients with acute myeloid leukemia. METHODS Thirty samples of patients with acute myeloid leukemia were studied, in which FLT3-ITD, FLT3-TKD and NPM1 mutations were investigated. All samples were submitted to immunophenotyping and 25 to ...
PURPOSE We evaluated leukemia-associated immunophenotypes (LAIP) and their correlation with fms-like tyrosine kinase 3 (FLT3) and nucleophosmin (NPM1) gene mutational status in order to contribute a better identification of patients at highest risk of relapse in acute myeloid leukemia (AML). EXPERIMENTAL DESIGN Bone marrow samples from 132 patients with AML were analyzed by nine-color multipa...
Acute myeloid leukemia (AML) is a heterogeneous disease. Even within the same NPM1-mutated genetic subgroup, some patients harbor additional mutations in FLT3, IDH1/2, DNMT3A or TET2. Recent studies have shown the prognostic significance of minimal residual disease (MRD) in AML but it remains to be determined which molecular markers are the most suitable for MRD monitoring. Recent advances in n...
Objectives The study aims to understand geneome diversi?cation and complexity that developed in Acute myeloid leukemia (AML).Methods Next-generation sequencing (NGS) was used identify the genetic pro?les of 22 genes relevant hematological malignancy 204 patients with de novo non-M3 AML.Results At time initial diagnosis, at least one mutation identified 80.9% (165/204). most commonly mutated gen...
Mutation status of FLT3, NPM1, CEBPA, and WT1 genes and gene expression levels of ERG, MN1, BAALC, FLT3, and WT1 have been identified as possible prognostic markers in acute myeloid leukemia (AML). We have performed a thorough prognostic evaluation of these genetic markers in patients with pediatric AML enrolled in the Nordic Society of Pediatric Hematology and Oncology (NOPHO) 1993 or NOPHO 20...
