Background: Refractoriness to platelet (PLT) transfusion is a feared, life-threatening complication in hematology-oncology patients. Despite increased PLT requirement and treatment costs, the clinical management is difficult and these patients had less favorable outcomes.
Case Report: We report on the efficacy of the thrombopoietic agent romiplostim in a patient with acute myeloid leukemia with chemotherapy-induced transfusion-refractory thrombocytopenia.
Conclusion: Romiplostim could be very helpfull in the management of AML patients with transfusion refractory thrombocytopenia.

CD226 plays a vital role in natural killer (NK) cell cytotoxicity, interacting with its ligands CD112 and CD155 to initiate immune synapse formation, primarily through leukocyte function-associated-1 (LFA-1). Our study examined the role of CD226 in NK cell surveillance of acute myeloid leukemia (AML). NK cells in patients with AML had lower expression of CD226.

Rearrangements of cytokine receptor-like factor 2 gene (CRLF2) are present in ∼50% of B-lymphoblastic leukemia/lymphoma (B-ALL) with BCR::ABL1-like features. Herein, we report three patients with CRLF2-rearranged mixed phenotype acute leukemia (MPAL). All three cases were B/myeloid MPAL in young patients harboring P2RY8::CRLF2 or IGH::CRLF2 with additional genomic alterations in signaling (JAK and RAS) and cell cycle (CDKN2A/B) pathways, a genomic profile similar to that in BCR::ABL1-like B-ALL.

Thus,eliminating LSC is one of the overarching goals of AML research. Radioimmunotherapyis an immunotherapeutic approach which utilizes radioactive isotopes aseffector molecules based on the proven ability of ionizing radiation (IR) tokill LSC.

Hypermethylation of tumor suppressor genes is a hallmark of leukemia. The hypomethylating agent decitabine covalently binds, and degrades DNA (cytosine-5)-methyltransferase 1 (DNMT1). Structural similarities within DNA-binding domains of DNMT1, and the leukemic driver histone-lysine N-methyltransferase 2A (KMT2A) suggest that decitabine might also affect the latter.

Background: Invasive fungal disease (IFD) poses significant challenges for critically ill patients with hematological malignancies (HMs). However, there is limited research on the clinical characteristics, risk factors, and outcomes of IFD within this population.
Method: A retrospective study was conducted at a tertiary center in China.
