TranscriptomicsCDKN1B encoding the cyclin-dependent kinase inhibitor 1B (p27) is located in the minimally deleted region of 12p abnormalities in myeloid malignancies and its low expression is a favorable prognostic marker in acute myeloid leukemia
Alterations of the short arm of chromosome 12 (12p) occur in various hematological malignancies and ETV6 and CDKN1B, which are located on 12p, have been implicated as leukemogenic genes of interest. Design and Methods: We selected 7 patients with myeloid malignancies and small 12p deletions by FISH ...

TranscriptomicsMultilineage dysplasia does not influence prognosis in patients with CEBPA mutated AML supporting the WHO proposal to classify these patients as a unique entity
By WHO 2008, CEBPA-mutated AML became a provisional subentity, but it remains to be clarified how CEBPAmut AML with multilineage dysplasia (MLD; ?50% dysplastic cells in 2-3 lineages) but no other MDS-related feature should be classified. We investigated 108 CEBPAmut AML (15.7-87.6 years) for the im...

TranscriptomicsAcute myeloid leukemia with CEBPA double-mutations harbors in 76.8% of cases concomitant molecular mutations with TET2 and GATA2 alterations demonstrating strong prognostic impact
Acute myeloid leukemia (AML) with CEBPA mutations is determined as provisional entity in the current WHO. A difference in clinical outcome between single- (sm) and double-mutated (dm) cases has been reported, whereupon dm cases were shown to be associated with longer overall survival (OS). The occur...

TranscriptomicsTranscription profiling of Multilineage Dysplasia (MLD) in AML correlates with MDS-related cytogenetic abnormalities and a prior history of MDS or MDS/MPN but has no independent prognostic relevance
Full Title: Multilineage Dysplasia (MLD) in AML correlates with MDS-related cytogenetic abnormalities and a prior history of MDS or MDS/MPN but has no independent prognostic relevance: A comparison of 408 cases classified as “AML not otherwise specified” or “AML with myelodysplasia-related changes” ...

TranscriptomicsAML with mutated NPM1 carrying a normal or aberrant karyotype show overlapping features
AML with mutated NPM1 usually carries normal karyotype (NK) but it may harbor chromosomal aberrations whose significance remains unclear. We addressed this question in 631 AML patients with mutated/cytoplasmic NPM1. An abnormal karyotype (AK) was present in 93/631 cases (14.7%), the most frequent ab...

TranscriptomicsMultilineage dysplasia and AML with mutated nucleophosmin
Multilineage dysplasia (MLD) has no impact on biological, clinico-pathological and prognostic features of AML with mutated nucleophosmin (NPM1) NPM1-mutated AML is a provisional entity in the WHO-2008 classification of myeloid neoplasms. The significance of concomitant multilineage dysplasia (MLD) i...

TranscriptomicsMicroRNA profiling of human acute myeloid leukemia samples from patients characterized for subcellular localization/mutation status of NPM1 and FLT3 mutations
Acute myeloid leukemia (AML) carrying NPM1 mutations and cytoplasmic nucleophosmin (NPMc+ AML) accounts for about one-third of adult AML and shows distinct features, including a unique gene expression profile. MicroRNAs (miRNAs) are small noncoding RNAs of 19-25 nucleotides in length that have been ...

TranscriptomicsMethylation of the Proximal, Distal and Core Promoter of CEBPA in 572 Cases with Normal Karyotpye AML and 44 with t(8;21) Disclosed Different Frequencies but no Impact on Prognosis
The clinical impact of aberrant CEBPA promoter methylation (PM) in AML is controversial discussed. The aim of this study was to clarify the significance of aberrant CEBPA PM with regard to clinical features in a cohort of 572 de novo AML with wildtype CEBPA and normal karyotype. The distal promoter ...

TranscriptomicsWhole-exome sequencing identifies mutations of BCOR in acute myeloid leukemia with normal karyotype
Among acute myeloid leukemias (AML) with normal karyotype (CN-AML), NPM1 and CEBPA mutations define WHO provisional entities accounting for ~60% of cases, but the remaining ~40% remains poorly characterized. By whole exome-sequencing (WES) of one CN-AML patient lacking mutations in NPM1, CEBPA, FLT3...
