Allogeneic Hematopoietic Cell Transplantation for Patients with Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)

Investigators reported on all 17 patients with BPDCN who underwent allogeneic hematopoietic cell transplantation (allo-HCT) at their center between 2000 and 2020, and concluded that allo-HCT provided long-lasting remissions in BPDCN patients, particularly when performed in complete remission.

A CIBERSORTx-Based Immune-Cell Scoring System Could Independently Predict Prognosis of Myelodysplastic Syndrome Patients

The authors adopted CIBERSORTx to estimate the relative fractions of 22 subtypes of immune cells in the bone marrow of 316 myelodysplastic syndrome patients and correlated the results with clinical outcomes.

p300 Suppresses the Transition of Myelodysplastic Syndromes to Acute Myeloid Leukemia

Scientists identified a tumor suppressor role of the acetyltransferase p300 in clinically relevant myelodysplastic syndromes models driven by mutations in the epigenetic regulators TET2, ASXL1, and SRSF2.
