BACKGROUND Myelodysplastic syndromes are heterogeneous disorders. Patients with myelodysplastic syndrome disease often have ineffective hematopoiesis, cytopenias, blood cell dysplasia in one or more cell types, and are at high risk for developing acute myeloid leukemia. In myelodysplastic syndrome, mutations of TP53 gene are usually associated with complex karyotype and confer a worse prognosis...

The transcription factor TWIST-1 is up-regulated in CD34(+) cells in myelodysplastic syndrome and is involved in resistance to apoptosis. There is evidence that TWIST-1 affects apoptosis via microRNAs (miRs). Expression of miRs was determined in myeloid cell lines and primary CD34(+) marrow cells from patients with myelodysplastic syndrome and healthy donors using NanoString/array and validated...

BACKGROUND Myelodysplastic syndromes are a heterogeneous group of clonal hematopoietic stem cell disorders characterized by ineffective hematopoiesis. Survivin is a member of the inhibitor of apoptosis family and suppresses apoptosis. Survivin also functions as a subunit of the chromosomal passenger complex for regulating mitosis with Aurora-B. Survivin and Aurora-B play an important role in ma...

The incidence of myelodysplastic syndromes increases with age and a high prevalence of co-morbid conditions has been reported in these patients. So far, risk assessment in myelodysplastic syndromes has been mainly based on disease status. We studied the prognostic impact of comorbidity on the natural history of myelodysplastic syndrome with the aim of developing novel tools for risk assessment....

Patient and physician characteristics associated with use of erythropoiesis-stimulating agents in myelodysplastic syndrome patients have not yet been described. Myelodysplastic syndrome patients diagnosed from 2001 to 2005 were identified from the Surveillance Epidemiology and End Results-Medicare database. Multivariate regressions examined the association between patient and physician characte...

BACKGROUND Intestinal Behçet's disease-like symptoms are rare complications of myelodysplastic syndrome and are often refractory to immunosuppressive therapies. We described a case of myelodysplastic syndrome complicated by Behçet's disease-like symptoms treated with prednisolone and azacitidine. CASE REPORT A 68-year-old Japanese woman was admitted to our hospital because of persistent high fe...

BACKGROUND Multiparameter flow cytometric analysis of bone marrow and peripheral blood cells has proven to be of help in the diagnostic workup of myelodysplastic syndromes. However, the usefulness of flow cytometry for the detection of megakaryocytic and platelet dysplasia has not yet been investigated. The aim of this pilot study was to evaluate by flow cytometry the diagnostic and prognostic ...

Therapy-related myelodysplastic syndrome in patients with acute promyelocytic leukemia is a rare event and the prognosis is poor. Allogeneic bone marrow transplantation is recently being reported as an effective treatment. We present a young patient with acute promyelocytic leukemia who developed myelodysplastic syndrome 52 months after complete remission. She underwent allogeneic peripheral bl...

Myelodysplastic syndromes represent particularly challenging hematologic malignancies that arise from a large spectrum of genetic events resulting in a disease characterized by a range of different presentations and outcomes. Despite efforts to classify and identify the key genetic events, little improvement has been made in therapies that will increase patient survival. Animal models represent...
