We report a 78-year-old male who, 3 years after treatment for acute monocytic leukaemia, developed t-MDS (refractory anaemia with excess blasts-2) that was initially suspected to be a relapse. Cytogenetic analysis of the initial AML had revealed +8 and del(16). These abnormalities ...
MDS and AML originate during CH from clonal hematopoiesis of indeterminate potential (CHIP) or clonal cytopenia of undetermined significance (CCUS), which falls into the category of clonal cytopenia (Fig.1a). CCUS can be distinguished from CHIP thanks to the advancements in NGS techniques. It repr...
Acute myeloid leukemia (AML) is caused by altered maturation and differentiation of myeloid blasts, as well as transcriptional/epigenetic alterations, all leading to excessive proliferation of malignant blood cells in the bone marrow. Tumor heterogeneity due to the acquisition of new somatic alterations ...
5 Definitive proof that a small population of leukemic stem cells produce the AML blasts comes from 6-week primary and secondary engraftment experiments in NOD/SCID mice.6 Further studies have revealed that these SCID-leukemia initiating cells (SL-ICs) share many properties with normal HSCs, ...
A less strict definition of blast cutoff in the updated WHO classification and ICC emphasizes a com- prehensive assessment of morphology, cytoge- netic, and molecular genetic analyses to classify MDS and/or AML. The ELN recommendations have also been updated in 2022, which stratified patients ...

方法选取2010年6月至2011年6月在山东大学附属省立医院血液科就诊的住院或门诊患者85例,包括AA组25例;MDS组48例,其中难治性贫血(refractoryanemia,RA)组22例,难治性贫血伴原始细胞增多(refractoryanemiawithexcessblasts,RAEB)组26例;AML组12例,另选取正常对照8例(均为非血液病患者),采用流式细胞仪(flowcytometry...
Updated results from the multicenter Phase 1b/2 trial demonstrated that APR-246 + AZA is a well-tolerated combination with high response rates in HMA-treatment naïve TP53 mutated higher risk MDS, MDS/MPN, and oligoblastic AML (20%-30% blasts) patients (NCT03072043). Patients enrolled...

Major clinically relevant changes introduced to the ELN 2022 recommendations for the diagnosis and management of AML Updates pertinent to the...
