Several prognostic scoring systems have been developed to assess prognosis in myelodysplastic syndrome (MDS). However, currently there are no systems that list gender as a prognostic factor. We queried a National Cancer Institute database to investigate the prognostic influence of gender on the survival of patients with MDS. Read More

Previous studies on the pathogenesis of myelodysplastic syndrome (MDS) have identified multiple associated gene mutations, including mutations of tetmethylcytosinedioxygenase 2, isocitrate dehydrogenase [NADP(+)] 1 cytosolic, isocitrate dehydrogenase [NADP(+)] 2 mitochondrial and additional sex combs like 1 transcriptional regulator, all of which may be considered epigenetic regulators. Furthermore, mutations of RAS type GTPase family genes have been identified in 10-15% patients with MDS. The authors' previous study on the gene expression profile of cluster of differentiation 34 cells using microarray analysis identified elevated expression of RAP1GTPase activating protein 1 (Rap1GAP) in patients with MDS compared with that in non-malignant blood diseases (NM) control group.

Myelodysplastic syndromes (MDS) and associated diseases, like chronic myelomonocytic leukemias (CMML), are heterogeneous, clonal disorders affecting the hematopoietic stem cells. They are characterized by dysplasia and a propensity to evolve toward acute myeloid leukemia. Systemic inflammatory and autoimmune manifestations (SIAMs) occur with a prevalence of 10% to 20% in myeloid malignancies, but the underlying pathogenetic mechanisms remain obscure. Read More

Erythropoiesis-stimulating agents are generally the first line of treatment of anemia in patients with lower-risk myelodysplastic syndrome. We prospectively investigated the predictive value of somatic mutations, and biomarkers of ineffective erythropoiesis including the flow cytometry RED score, serum growth-differentiation factor-15, and hepcidin levels. Inclusion criteria were no prior treatment with erythropoiesis-stimulating agents, low- or intermediate-1-risk myelodysplastic syndrome according to the International Prognostic Scoring System, and a hemoglobin level <10 g/dL.

Aims: Refractory cytopenia of childhood (RCC) is subdivided into myelodysplastic syndrome with multilineage dysplasia (MDS-MLD) and RCC without (w/o) multilineage dysplasia (RCC without MLD). Although RCC is a histomorphological distinct entity, the bone marrow (BM) histology of RCC is not yet characterised in relation to multilineage dysplasia. We investigated the BM histological features of RCC to clarify the characteristics of BM histology of MDS-MLD in childhood compared to RCC without MLD. Read More

Rationale: Myelodysplastic syndrome (MDS) is a heterogeneous malignant hematologic disease with median overall survival ranging from six months to more than ten years. Solid tumor rarely occurs in combination with MDS and the underlying pathogenesis and prognostic significance still remain controversial.

Patient Concerns: Here we report a relative low risk myelodysplastic syndrome-refractory cytopenia with multilineage dysplasia (MDS-RCMD) patient, with a rare t(1; 19)chromosome translocation. Read More

Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic disorders related to hematopoietic stem and progenitor cell dysfunction. Several studies have shown the role of the bone marrow microenvironment in regulating hematopoietic stem, and progenitor function and their individual abnormalities have been associated with disease pathogenesis. In this study, we simultaneously evaluated hematopoietic stem cells (HSC), hematopoietic stem progenitor cells (HSPCs) and different stromal elements in a cohort of patients with MDS-refractory cytopenia with multilineage dysplasia (RCMD).

Refractory cytopenia of childhood (RCC) was proposed as a provisional entity in the 2008 WHO classification of myelodysplastic syndromes (MDS). It is defined as a childhood MDS featuring persistent cytopenia without increase blasts in bone marrow (BM) or peripheral blood (PB). Because the majority of RCC cases feature hypocellularity and pancytopenia, it is quite challenging to differentiate RCC from acquired aplastic anemia (AA) and many kinds of inherited bone marrow failure syndromes (IBMFS).

Tumor protein 53 mutations adversely affect the prognosis of myelodysplastic syndromes (MDS); however, few studies have reported on the prognostic significance of the expression of p53 protein in MDS. The current study investigated p53 immunoreactivity (p53-IR) in bone marrow biopsies (BMBs) obtained at diagnosis from 18 patients (6 females and 12 males; mean age, 50.5 years) with MDS that underwent bone marrow transplantation (BMT) to determine the associations between clinical and histopathological data and outcome.

A 64-year-old woman was diagnosed to have refractory cytopenia with multilineage dysplasia (RCMD) including an increased number of sideroblasts in the bone marrow (BM). Computed tomography (CT) revealed a presacral mass which showed iso- or high-intensity signals according to T1-weighted and hypo-intensity signals on T2-weighted magnetic resonance imaging (MRI). CT-guided biopsy revealed the presence of hematopoietic tissue with features that correlated with the BM findings. Read More

Myelodysplastic syndromes (MDS) represent a heterogeneous group of pre-leukemic disorders, characterized by ineffective hematopoiesis and the abnormal blood cell development of one or more lineages. Oxidative stress, as an important factor in the carcinogenesis of onco-hematological diseases, is also one of the known factors involved in the pathogenesis of MDS. An increase of reactive oxygen species (ROS) may lead to the oxidation of DNA, lipids, and proteins, thereby causing cell damage. Read More

Context: -At the initial diagnosis of myelodysplastic syndrome (MDS) and/or during follow-up, the evaluation of chromosomal abnormalities is based on standard G-banding, whereas the utility of fluorescence in situ hybridization (FISH) is still debated.

Objectives: -To investigate whether interphase fluorescence in situ hybridization (iFISH) clone size at initial diagnosis of MDS is correlated with survival and whether changes in clonal fraction by iFISH are concordant with the MDS International Working Group response criteria during follow-up.

Design: -A tailored FISH panel (-5/5q-, -7/7q-, +8, -20/20q-, and +1/1q+), based on reported cytogenetic changes in Korean patients with MDS, was performed in 81 patients with MDS at initial diagnosis and in 28 patients during follow-up. Read More

The sideroblastic anemias are a heterogeneous group of inherited and acquired disorders characterized by the presence of ring sideroblasts in the bone marrow. X-linked sideroblastic anemia (XLSA) is caused by germline mutations in ALAS2.

In recent years the plasma proteomes of several different myelodysplastic syndrome (MDS) subgroups have been investigated and compared with those of healthy donors. However, the resulting data do not facilitate a direct and statistical comparison of the changes among the different MDS subgroups that would be useful for the selection and proposal of diagnostic biomarker candidates. The aim of this work was to identify plasma protein biomarker candidates for different MDS subgroups by reanalyzing the proteomic data of four MDS subgroups: refractory cytopenia with multilineage dysplasia (RCMD), refractory anemia or refractory anemia with ringed sideroblasts (RA-RARS), refractory anemia with excess blasts subtype 1 (RAEB-1), and refractory anemia with excess blasts subtype 2 (RAEB-2).

Refractoriness to growth factor therapy is commonly associated with inferior outcome in patients with low-risk myelodysplastic syndrome (LR-MDS) who require treatment for cytopenias. However, the mechanisms leading to refractoriness are unknown. Here we describe a clinically depressed 74-year-old male with refractory cytopenia with multilineage dysplasia (RCMD) and documented growth factor refractory anemia after erythropoeisis stimulating agent (ESA) therapy, who attained transfusion and growth factor independence after the addition of sertraline to his medication regimen.

Myelodysplastic syndromes (MDS) are heterogeneous clonal disorders characterized by cytopenias that arise due to ineffective haematopoiesis and morphological dysplasia and carry an increased risk of incident acute myeloid leukaemia. The pathogenesis of marrow dysfunction in MDS is multifactorial and consistent with a multistep model and may lead to heterogeneity of MDS. We investigated the proteome profile of circulating neutrophils purified from patients with refractory cytopenia with multilineage dysplasia (RCMD) to identify proteins that have a role in the pathogenesis.
