Herein, we present a rare case of acute myeloid leukemia (AML) with CBFA2T3-rearrangement and the expression of megakaryocytic and lymphoid markers, highlighting the need for a high suspicion index in differential diagnosis and applying adequate workup to avoid misdiagnosing this entity. -positive AML is primarily found in infants with non-down syndrome acute megakaryoblastic leukemia (non-DSAMKL). Flow cytometry immunophenotyping plays an important role in recognizing the unique immunophenotype of bright CD56 expression with dim/negative expression of HLA-DR, CD38, and CD45 termed the RAM immunophenotype in this entity. Still, CBFA2T3::GLIS2-positive acute leukemia with T/megakaryocytic markers could be misdiagnosed as T-lymphoblastic leukemia/lymphoma, early T-cell precursor acute lymphoblastic leukemia/lymphoma, NK lymphoblastic leukemia, AML with minimal differentiation, or AML with myelodysplasia-related changes.

Introduction: Hematologic malignancies, originating from uncontrolled growth of hematopoietic and lymphoid tissues, constitute 6.5% of all cancers worldwide. Various risk factors including genetic disorders and single nucleotide polymorphisms play a role in the pathogenesis of hematologic malignancies.

The chemotherapy and venetoclax in elderly AML trial (CAVEAT) was first to combine venetoclax with intensive chemotherapy in newly diagnosed patients ≥65 years. In this final analysis, 85 patients (median age 71 years) were followed for a median of 41.

Objectives: To investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL) in children.
Methods: A retrospective analysis was conducted on the clinical data, treatment, and prognosis of 8 children with AEL treated at the First Affiliated Hospital of Zhengzhou University from January 2013 to December 2023.
Results: Among the 7 patients with complete bone marrow morphological analysis, 4 exhibited trilineage dysplasia, with a 100% incidence of erythroid dysplasia (7/7), a 71% incidence of myeloid dysplasia (5/7), and a 57% incidence of megakaryocytic dysplasia (4/7).

To guide clinical blood transfusion practices for pediatric patients, the National Health Commission has issued the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Blood transfusion is one of the most commonly used supportive treatments for children with hematological diseases. This guideline provides guidance and recommendations for blood transfusions in children with aplastic anemia, thalassemia, autoimmune hemolytic anemia, glucose-6-phosphate dehydrogenase deficiency, acute leukemia, myelodysplastic syndromes, immune thrombocytopenic purpura, and thrombotic thrombocytopenic purpura.

Anti-CD19 chimeric antigen receptor T cells (CAR) are a well-established treatment option for children and young adults suffering from relapsed/refractory B-lineage acute lymphoblastic leukemia. Bridging therapy is used to control disease prior to start of lymphodepletion before CAR infusion and thereby improve efficacy of CAR therapy. However, the effect of different bridging strategies on outcome, side effects and response to CAR therapy is still poorly understood.
