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...

Myelodysplastic syndromes (MDS) are a collection of heterogeneous clonal stem cell disorders that lead to ineffective hematopoiesis and multi-lineage cytopenia. Treatment options for MDS patients are limited and its pathogenesis remains unelucidated. In recent years, sequencing studies have uncovered recurrent mutations in MDS. Particularly, mutations in the RNA splicing machinery have generated great interest since it is one of the most frequently mutated pathways. Mutations of SRSF2, a spliceosome component, are found in high-risk MDS (12 –15%) or chronic myelomonocytic leukaemia (CMML; 40–50%)- an aggressive...

We recently conducted a randomized double-blind study in which we demonstrated that moderate/severe chronic graft-versus-host disease (cGVHD) but not cGVHD-free survival was reduced in patients receiving anti-T lymphocyte globulin (ATLG) versus placebo. In a companion study we performed immunophenotypic analysis to determine the impact of ATLG on immune reconstitution (IR) and to correlate IR with clinical outcomes. The randomized study (n  = 254) included patients (aged 18 to 65 years) who underwent myeloablative transplants for acute myeloid leukemia, myelodysplastic syndrome, or acute lymphoblastic leukemia from HLA...

Conclusions: Therapy-related CML has a clinical presentation, pathologic features, and cytogenetic profile akin to de novo CML. Absence of additional significant aberrations seems to suggest a pathogenesis different from therapy-related AML/MDS. Therapy-related CML exhibits a robust therapeutic response to imatinib/derivatives and favorable clinical outcomes similar to de novo CML. PMID: 29992292 [PubMed - as supplied by publisher]

AbstractThe myelodysplastic syndromes, the chronic myeloproliferative neoplasms, and the acute myeloid leukemia are malignancies of the myeloid hematopoietic stem cells of the bone marrow. The diseases are characterized by a dysregulation of the immune system as both the cytokine milieu, immune phenotype, immune regulation, and expression of genes related to immune cell functions are deregulated. Several treatment strategies try to circumvent this deregulation, and several clinical and preclinical trials have shown promising results, albeit not in the same scale as chimeric antigen receptor T cells have had in the treatmen...
