Myelodysplastic syndrome (MDS) and myeloproliferative disorders are rare in children; they are divided into low-grade MDS (refractory cytopenia of childhood [RCC]), advanced MDS (refractory anemia with excess blasts in transformation), and juvenile myelomonocytic leukemia (JMML), each with different characteristics and management strategies. Underlying genetic predisposition is recognized in an increasing number of patients. Germ line GATA2 mutation is found in 70% of adolescents with MDS and monosomy 7. It is challenging to distinguish RCC from aplastic anemia, inherited bone marrow failure, and reactive conditions...

Atypical chronic myeloid leukemia, BCR-ABL1-negative (aCML) is a rare myelodysplastic syndrome/myeloproliferative neoplasm for which no current standard of care exists. The challenges of atypical CML relate to its heterogeneous clinical and genetic features, high rate of transformation to acute myeloid leukemia, and historically poor survival. Therefore, allogeneic hematopoietic stem cell transplantation should always be an initial consideration for eligible patients with a suitable donor. Non-transplant approaches for treating aCML have otherwise largely relied on adopting treatment strategies used for MDS and MPN...

In this review, we provide an overview of familial myelodysplastic syndromes (MDS)/acute leukemia (AL) and bone marrow failure syndromes, as well as insights into familial myeloproliferative neoplasms (MPNs), familial multiple myeloma (MM), familial Waldenström macroglobulinemia (WM), familial lymphoma, and cancer predisposition syndromes with increased risk of MDS/AL. This field will continue to accelerate as next-generation sequencing (NGS) techniques identify novel predisposition alleles in families with a genetic predisposition to hematologic malignancies...

Splanchnic vein thrombosis (SVT) is one of the vascular complications of myeloproliferative neoplasms (MPN). We designed a phase 2 clinical trial to evaluate safety and efficacy of ruxolitinib in reducing splenomegaly and improving disease-related symptoms in patients with MPN-associated SVT. Patients, diagnosed with myelofibrosis in 12 cases, polycythemia vera in 5 and essential thrombocythemia in 4, received ruxolitinib for 24 weeks in the core study period. Spleen volume was assessed by magnetic resonance imaging (MRI) and splanchnic vein circulation by echo-Doppler analysis...

This is the report of the clinical case of a patient who presents the association of a JAK-2 positive chronic myeloproliferative neoplasia to a subsequent 5q- myelodysplastic syndrome, developed after about 14 years from the first diagnosis. Patient's symptoms had rapidly worsened, and she became transfusion-dependent. Therapy with low-dose Lenalidomide quickly reduced the splenomegaly and completely brought white cells counts, haemoglobin, and platelets back to normal. After more than one year from the start, blood cell count is still normal...

Therapy-related acute myeloid leukemia (t-AML) is a heterogeneous entity most frequently related to breast cancer or lymphoproliferative diseases (LD). Population-based studies have reported an increased risk of t-AML after treatment of lymphomas. The aim of this study was to describe the characteristics and outcome of 80 consecutive cases of t-AML following treatment of LD. t-AML accounted for 2.3% of all AML cases, occurred 60 months after LD diagnosis, and were characterized by a high frequency of FAB M6 AML and poor-risk cytogenetic abnormalities...

We retrospectively studied 181 patients with polycythaemia vera (n=67), essential thrombocythaemia (n=67) or primary myelofibrosis (n=47), who presented a first episode of splanchnic vein thrombosis (SVT). Budd-Chiari syndrome (BCS) and portal vein thrombosis were diagnosed in 31 (17.1%) and 109 (60.3%) patients, respectively; isolated thrombosis of the mesenteric or splenic veins was detected in 18 and 23 cases, respectively. After this index event, the patients were followed for 735 patient years (pt-years) and experienced 31 recurrences corresponding to an incidence rate of 4...

REVIEW

The 8p11 eosinophilic myeloproliferative syndrome (EMS) is an aggressive neoplasm driven by translocation of the fibroblast growth factor receptor 1 and often transforms to leukemias and lymphomas that are refractory to treatment. The first case was identified in 1983, and to date over 70 cases have been reported in the literature. Despite those reports, no consensus exists on management of this condition, and inconsistency in treatment regimens is even more pronounced in the pediatric literature. We report a case of a male infant with the 8p11 EMS, review the published pediatric experience with EMS, and discuss treatment strategies for this enigmatic hematological disorder...

The myelodysplastic/myeloproliferative neoplasms (MDS/MPNs) are a unique group of hematologic malignancies characterized by concomitant myelodysplastic and myeloproliferative features. According to the 2008 WHO classification, the category includes atypical chronic myeloid leukemia (aCML), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia (JMML), MDS/MPN-unclassifiable (MDS/MPN-U), and the provisional entity refractory anemia with ring sideroblasts and thrombocytosis (RARS-T). Although diagnosis currently remains based on clinicopathologic features, the incorporation of next-generation platforms has allowed for the recent molecular characterization of these diseases which has revealed unique and complex mutational profiles that support their distinct biology and is anticipated to soon play an integral role in diagnosis, prognostication, and treatment...

BACKGROUND: China may have the largest number of Budd-Chiari syndrome (BCS) cases in the world (at least 1914 original papers were published, and at least 20 191 BCS patients were reported). Considering the discrepancy in the clinical profiles and preferred treatment selection of primary BCS between the West and China, understanding its aetiology in these two different regions is very important. AIM: To review the data from large cohort studies and meta-analyses to illustrate the epidemiology of risk factors for BCS in the West and China...

Current treatment of acute myeloid leukemia (AML) still relies on intensive chemotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). AML is a heterogeneous neoplasm characterized by distinct chromosomal and genetic abnormalities. Recent comprehensive gene analyses have highlighted distinct genetic subgroups that are associated with different responses to chemotherapy. Therefore, the molecular landscape of AML is fundamental to the development of novel therapeutic approaches and provides opportunities for individualization of therapy...

Chronic myeloid leukemia (CML) is a myeloproliferative syndrome characterized by the presence of the Philadelphia chromosome which encodes a constitutively activated tyrosine kinase (BCR-ABL). The first line treatment for CML consists on BCR-ABL inhibitors such as Imatinib. Nevertheless, such treatment may lead to the selection of resistant cells. Therefore, it is of great value to find molecules that enhance the anti-proliferative effect of first-line drugs. Hyaluronan is the main glycosaminglican of the extracellular matrix which is involved in tumor progression and multidrug resistance...

Myelodysplastic syndrome (MDS) cases comprise a heterogeneous group of hematological disorders that are characterized by impaired hematopoiesis, with cytopenias of different grades and risk of developing acute myeloid leukemia. MDS may rarely be associated with thrombocytosis. In such cases, myelodysplasia and myeloproliferative disorders may overlap, making correct diagnosis difficult. We herein describe a case of MDS with thrombocytosis, Janus kinase 2 gene mutation-positive and Perls' staining-negative, which was initially classified as essential thrombocythemia (ET)...

Jauns kinase (JAK)/transducer and activator of transcription(STAT) pathway is a classical approach to study the rapid changes of the gene expression in specific target cells by a variety of extracellular signals. The JAK and STAT transfer cytokine receptor signaling plays a unique role in multiple cellular and molecular biological changes.The abnormal signal of JAK/STAT pathway will lead to the hematopoietic abnormalities.Studies had shown that the abnormal activation of JAK2/STAT signaling pathway are in many kinds of malignant hematological diseases, such as in acute lymphoblastic/myeloid leukemia, chronic myeloid leukemia, lymphoma, myelodysplastic syndromes, myeloprofilerative neoplasm, especially in the patients of myeloproliferative neoplasm(MPN) with JAK gene mutation(JAK2V617F), this mutation has an important value for MPN diagnosis...

Ingenol mebutate (IM) has recently been approved for the topical treatment of actinic keratoses. It appears to have a dual mechanism of action: rapid necrosis after gel application and a subsequent immune-mediated response, which targets any residual dysplastic epidermal cells. We report the successful treatment of a woman, who had been relapsing into Bowen's disease (BD) on her right forefinger for 8 years. During her clinical history, she had received an allogeneic, HLA-identical stem cell transplant for myeloproliferative syndrome with a JAK2V617F mutation and lobectomy of the pulmonary right lower lobe for adenocarcinoma...

UNLABELLED: Although allogeneic haematopoietic stem cell transplantation (allo-HSCT) offers a unique curative potential, it may be connected with high treatment-related morbidity and mortality. Besides many organ complications, allo-HSCT may significantly affect quality of life (QOL). PATIENTS AND METHODS: Between January 2011 and December 2012, five hundred and ninety patients (pts) from 6 transplant centers in the Czech Republic filled in the questionnaire for the quantitative measurement of QOL using Functional Assessment of Cancer Therapy-General (FACT-G) version 4...

Myeloid sarcoma (MS) is a rare extramedullary tumor composed of immature cells of myeloid lineage that destroy the original tissue architecture in which it is found. It is most commonly identified in patients with acute myelogenous leukemia, and less often in myelodysplastic syndromes (MDSs) and other myeloproliferative disorders. It is most commonly reported in the periosteum, bone, skin, and lymph nodes but has been reported in many other sites of the body. Herein, we describe a case of MS involving the periprostatic tissue and review of literature of MS of the prostate...

Hypereosinophilic syndrome (HES) is a myeloproliferative disorder characterised by marked peripheral eosinophilia and end organ damage attributable to eosinophilia without secondary cause. Early recognition and treatment are essential to prevent morbidity and mortality. Cytoreduction with Steroids, Hydroxyurea and Imatinib are the main stay of treatment. Molecular studies like Fip1-like-1 fused with platelet derived growth factor receptor alpha (FIP1L1-PDGFRα) etc., are recommended in view of therapeutic implication...

Perturbations in CREB binding protein (CREBBP) are associated with hematopoietic malignancies, including myelodysplastic syndrome (MDS). Mice hemizygous for Crebbp develop myelodysplasia with proliferative features, reminiscent of human MDS/myeloproliferative neoplasm-unclassifiable (MDS/MPN-U), and a proportion goes on to develop acute myeloid leukemia (AML). We have also shown that the Crebbp+/- non-hematopoietic bone marrow microenvironment induces excessive myeloproliferation of wild-type cells. We now report that transplantation of unfractionated Crebbp+/- bone marrow into wild-type recipients resulted in either early-onset AML or late-onset MDS and MDS/MPN-U...

BACKGROUND: The incidence of alloimmunisation in myelodysplastic syndromes (MDS) during the era of supportive treatment ranges from 9 to 56%. However, it is unknown if the widespread use of hypomethylating agents has changed the risk of immunisation. The aim of this study is to evaluate the impact of azacitidine (AZA) therapy on red blood cell (RBC) alloimmunisation in transfused patients with MDS, myelodysplastic syndromes/myeloproliferative syndromes (MDS/MPS) and secondary acute myeloid leukaemia (AML)...
