Survival in MDS Equivalent With Reduced-Intensity Conditioning

Patients with myelodysplastic syndrome undergoing a reduced –intensity conditioning regimen prior to allogeneic stem-cell transplantation had similar 2-year survival outcomes as patients who underwent myeloablative conditioning.

Monosomy 7 (–7) and del(7q) are high-risk cytogenetic abnormalities common in myeloid malignancies. We previously reported that CUX1, a homeodomain-containing transcription factor encoded on 7q22, is frequently inactivated in myeloid neoplasms, and CUX1 myeloid tumor suppressor activity is conserved from humans to Drosophila. CUX1-inactivating mutations are recurrent in clonal hematopoiesis of indeterminate potential as well as myeloid malignancies, in which they independently carry a poor prognosis. To determine the role for CUX1 in hematopoiesis, we generated 2 short hairpin RNA-based mouse models with ~54% (Cux1mi...

Myelodysplastic syndromes (MDS) are clonal disorders of hematopoietic stem cells that mainly affect the elderly, characterized by ineffective hematopoiesis, leading to cytopenia, infections, and a significant reduction in the quality of life [1,2]. Intensive chemotherapy combined with hematopoietic stem cell transplantation (HSCT) is the only curative treatment for this disease. However, it's applicability in elderly patients is limited by comorbidities and poor performance status. Azacytidine (AZA) significantly reduces transfusion dependence, decreases the risk of transformation to acute myeloid leukemia (AML), and impro...

We report here indiscriminate killing of CD123+ normal and acute myeloid leukemia / myelodysplastic syndrome cells by SL-401, a diphtheria toxin interleukin-3 fusion protein. SL-401 induced cytotoxicity of CD123+ primary cells/blasts from acute myeloid leukemia and myelodysplastic syndrome patients but not CD123- lymphoid cells. Importantly, SL-401 was highly active even in cells expressing low levels of CD123, with minimal effect on modulation of the CD123 target in acute myeloid leukemia. SL-401 significantly prolonged survival of leukemic mice in acute myeloid leukemia patient-derived xenograft mouse models. In addition...

CONCLUSIONS: We found no evidence to determine the safety and efficacy of therapeutic platelet transfusion compared with prophylactic platelet transfusion for people with long-term bone marrow failure disorders. This review underscores the urgency of prioritising research in this area. People with bone marrow failure depend on long-term platelet transfusion support, but the only trial that assessed a therapeutic strategy was halted. There is a need for good-quality studies comparing a therapeutic platelet transfusion strategy with a prophylactic platelet transfusion strategy; such trials should include outcomes that are im...

In patients with myeloid malignancies, such as acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS), relapse remains the main cause of treatment failure after allogeneic hematopoietic stem cell transplantation (allo-HSCT) [1-4]. Several studies addressing therapeutic strategies for relapse after allo-HSCT have shown that treatment is more effective when initiated at molecular relapse rather than at hematologic relapse [5]. Therefore, early detection of imminent relapse, ideally at a molecular level, is a prerequisite for successful therapeutic intervention and can be achieved by regular monitoring of minimal...

This multicenter study evaluated a treosulfan-based regimen in children and young adults with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic cell transplant (HCT). Forty patients with median age 11 years (1-19) underwent allogeneic HCT for AML in first (n=18), second (n=11), third or greater remission (n=3); or MDS (n=8) using bone marrow (n=25), peripheral blood stem cells (n=5) or cord blood (n=9). The regimen consisted of body surface area (BSA)-based treosulfan 10 g/m2/day (BSA ≤ 0.5 m2), 12 g/m2/day (BSA> 0.5 – 1.0 m2), or 14 g/m2/day (BSA> 1.0 m2) on ...

Hematologic malignancies are more prevalent in older patients, and because of the increased rate of elderly in the population, the number of patients presenting with hematologic malignancy has increased [1]. The median ages of patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS), which are the most common indication for allogeneic hematopoietic transplantation (alloHCT), in this population are 69 and 76 years, respectively [2-4]. Despite the advent of the novel agents, alloHCT remains the only curative option for most of the common hematologic malignancies.

AbstractPrimary graft failure can be a cause of early morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT), as it leads to a high risk of severe infections and bleeding. Splenomegaly is associated with primary graft failure in patients of myelofibrosis, but the association between splenomegaly and outcomes after HSCT in patients with myeloid malignancies has not been previously evaluated. The aim of this study was to investigate the effect of spleen volume on engraftment kinetics in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). We enrolled 85 patients. The...
