Patients with primary plasma cell leukemia (pPCL), particularly those with extramedullary disease (EMD), face a poor prognosis even with chimeric antigen receptor (CAR)-T cell therapy. This case report describes a patient with relapsed/refractory pPCL and life-threatening malignant pleural effusion (PE) treated with intrapleural CAR-T cells targeting B-cell maturation antigens. CAR-T cell expansion within the PE was observed, along with a rapid reduction in leukemia cell count and PE volume.

Pediatric acute myeloid leukemia (pAML) is a heterogeneous malignancy driven by diverse cytogenetic mutations. While identification of cytogenetic lesions improved risk stratification, prognostication remains inadequate with 30% of standard-risk patients experiencing relapse within 5 years. To deeply characterize pAML heterogeneity and identify poor outcome-associated blast cell profiles, we performed an analysis on 708,285 cells from 164 bone marrow biopsies of 95 patients and 11 healthy controls.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HCT) is a key treatment for acute myeloid leukemia (AML). Measurable residual disease (MRD) predicts post-transplant outcomes. This study evaluates the impact of pretransplant MRD status on outcomes in AML patients undergoing allo-HCT.

Primary plasma cell leukemia (pPCL) is a rare and aggressive subtype of plasma cell malignancy. Although hematopoietic stem cell transplantation (HCT), including autologous HCT (auto-HCT) and allogeneic HCT (allo-HCT), is widely used, an optimal treatment strategy is undetermined. We retrospectively analyzed patients with pPCL who underwent HCT between 2006 and 2022 in Japan using Japanese registry data.

Crosstalk between leukemic cells and their surrounding mesenchymal stromal cells (MSCs) in the bone marrow microenvironment is crucial for the pathogenesis of myelodysplastic syndromes (MDS) and is mediated by extracellular vesicles (EVs). The EV-specific miRNAs derived from MDS-MSCs remain poorly explored. EVs isolated from HS-5, an immortalized stromal cell line, promoted the proliferation and 5-azacytidine (AZA) resistance of SKM-1 cells.
