BACKGROUND The World Health Organization separates acute erythroid leukemia (erythropoiesis in ≥50% of nucleated bone marrow cells; ≥20% myeloblasts of non-erythroid cells) from other entities with increased erythropoiesis - acute myeloid leukemia with myelodysplasia-related changes (≥20% myeloblasts of all nucleated cells) or myelodysplastic syndromes - and subdivides acute erythroid leukemia ...

A growing body of evidence suggests that childhood leukemia may be initiated in utero when lymphoid and myeloid cells are not fully differentiated and are particularly susceptible to malignant transformation. A fixed effects meta-analysis examining the association between birth weight and childhood leukemia was conducted including 32 studies and 16,501 cases of all types of leukemia (OL), 10,97...

BACKGROUND Biphenotypic acute leukemia is a rare disorder that is difficult to diagnose. It displays features of both myeloid and lymphoid lineage. There is still a lack of studies in biphenotypic acute leukemia in a Chinese population. We present here a comprehensive investigation of the clinical and biological characteristics, and outcome of biphenotypic acute leukemia in our hospital in over...

The recent identification of DNMT3A mutations in de novo acute myeloid leukemia prompted us to determine their frequency, patterns and clinical impact in a cohort of 98 patients with either therapy-related or secondary acute myeloid leukemia developing from an antecedent hematologic disorder. We identified 24 somatic mutations in 23 patients with a significantly higher frequency in secondary ac...

This summary is intended to update the Brazilian Society of Bone Marrow Transplantation and Cellular Therapy (SBTMO) 2020/1 consensus on HSCT for Acute Myeloid leukemia (AML).

The clinical relevance of myeloid antigen expression in childhood ALL as prognostic factor remains controversial. Some studies showed that children with myeloid-positive ALL had a poorer clinical outcome compared with those of meloid-negative ALL patients. In our population, myeloid antigen was expressed in 25% of ALL patients. They were treated with Indonesia 2006 ALL protocol. ABSTRACT The fr...

Acute leukemia is the most common type of childhood and adolescence cancer, characterized by clonal proliferation of variably differentiated myeloid or lymphoid precursors. Recent insights into the molecular pathogenesis of leukemia have shown that epigenetic modifications, such as deacetylation of histones and DNA methylation, play crucial roles in leukemogenesis, by transcriptional silencing ...
