Chronic Graft-Versus-Host Disease and Disease Status at Relapse as Predictors of Clinical Outcomes in Patients Receiving Azacitidine & Donor Lymphocyte Infusions as Salvage Therapy for Post Allograft Relapse of Myeloid Neoplasms

Background: Azacitidine (Aza) and donor lymphocyte infusions (DLI) confer survival advantage with improved tolerability for patients with relapsed acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) following allogenic stem cell transplantation (SCT).

In this study, genetic mouse models and patient-derived xenografts demonstrated that JARID2 acts as a tumor suppressor in chronic myeloid disorders. Genetic deletion of Jarid2 either reduced overall survival of animals with MPNs or drove transformation to sAML, depending on the timing and context of co-operating mutations. Mechanistically, JARID2 recruits PRC2 to epigenetically repress self-renewal pathways in hematopoietic progenitor cells. These studies establish JARID2 as a bona fide hematopoietic tumor suppressor and highlight potential therapeutic targets.Graphical Abstract

Myelodysplastic syndromes (MDS) encompass a heterogeneous group of clonal hematopoietic stem cell disorders characterized by a broad clinical spectrum related to ineffective hematopoiesis leading to unilineage or multilineage cytopenias, with a high propensity for transformation to acute myeloid leukemia. Iron overload has been recently identified as one of the important conditions complicating the management of these diverse disorders. The accumulation of iron is mainly related to chronic transfusions; however, evidence suggests a possible role for ineffective erythropoiesis and increased intestinal absorption of iron, re...

Conclusion: Pulmonary fungal infections are resistant to treatments for hematological malignancies. Since the treatment of the underlying disease is extended and these infections often recur and are exacerbated, surgery should be considered when possible. PMID: 30402396 [PubMed]

(University of Texas M. D. Anderson Cancer Center) The University of Texas MD Anderson Cancer Center and Cyclacel Pharmaceuticals, Inc., today announced a three-year strategic alliance agreement that will enable clinical evaluation for safety and efficacy of three Cyclacel medicines in patients with hematological malignancies, including chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) and other advanced leukemias.

In this study, genetic mouse models and patient-derived xenografts (PDX) demonstrated that Jarid2 acts as a tumor suppressor in chronic myeloid disorders. Genetic deletion of Jarid2 either reduced overall survival of MPN, or drove transformation to sAML, depending on the timing and context of co-operating mutations. Mechanistically, Jarid2 recruits PRC2 to epigenetically repress self-renewal pathways in hematopoietic progenitor cells.

Dysregulation of the B-cell leukemia/lymphoma-2 (BCL-2) family of proteins of the intrinsic apoptotic pathway is fundamental to the pathophysiology of many hematologic malignancies. The BCL-2 family consists of regulatory proteins that either induce apoptosis (proapoptotic) or inhibit it (prosurvival). BCL-2, myeloid cell leukemia-1, and B-cell lymphoma–extra large are prosurvival proteins that are prime targets for anticancer therapy, and molecules targeting each are in various stages of preclinical and clinical development. The US Food and Drug Administration (FDA)-approved BCL-2 inhibitor venetoclax was first prov...

CONCLUSION: The findings were consistent with transformation of ET to MDS with fibrosis and complex karyotype. ET progression to MDS is considered rare. The presence of complex karyotype and fibrosis in MDS are associated with unfavourable outcome. PMID: 30173238 [PubMed - in process]

z M, Alousi A, Couriel D, Pidala J, Arora M, Cutler C Abstract Upper gastrointestinal acute graft-versus-host disease is reported in approximately 30% of hematopoietic stem cell transplant recipients developing acute graft-versus-host disease. Currently classified as Grade II in Consensus criteria, upper gastrointestinal acute graft-versus-host disease is often treated with systemic immunosuppression. We reviewed the Center for International Blood and Marrow Transplant Research database to assess prognostic implications of upper gastrointestinal acute graft-versus-host disease in isolation or with other acute graf...

We aimed to assess bi-directional associations between myeloid cancers and other cancers—ie, development of second prim...
