Aim of this study is to explore the role of different treatments on the development of secondary malignancies (SMs) in a large cohort of essential thrombocythemia (ET) patients. We report the experience of a regional cooperative group in a real-life cohort of 1026 patients with ET. We divided our population into five different groups: group 0, no treatment; group 1, hydroxyurea (HU); group 2, alkylating agents (ALK); group 3, ALK + HU sequentially or in combination; and group 4, anagrelide (ANA) and/or α-interferon (IFN) only...

The 2016 revised WHO criteria for the diagnosis of pre-fibrotic/early primary myelofibrosis (pre-PMF) require at least one of the following four borderline expressed minor clinical criteria: anemia, leukocytosis, elevated lactate dehydrogenase and splenomegaly. In this study, we evaluated the relative frequency of these four criteria in a group of 170 pre-PMF patients and compared them to 225 ET cases. More than 91% of pre-PMF cases showed one or more of these features required for diagnosis, by contrast with only 48...

The molecular characterization of myeloproliferative neoplasms (MPN), including essential thrombocythemia (ET), has enabled deeper understanding of their pathogenesis. A driver lesion, namely, Janus kinase (JAK)2V617F, calreticulin (CALR) or myeloproliferative leukemia (MPL) gene mutation can be identified in the vast majority of patients. Each of these mutations is associated with distinct clinical features and may modulate the patients' clinical course, risk of complications, including vascular events, and survival...

MicroRNA-375 (miR-375) is expressed at low levels in many types of solid tumor, particularly in gastrointestinal tumors. It is considered to be important in the development of cancer and certain diseases. Thus, more detailed knowledge is required on the particular functions of miR-375. miRs function by regulating target genes. Therefore, in the current study, miRWalk (which includes the data from 10 prediction software programs) was used to predict the target genes of miR-375. The genes, which were co-predicted using five different software programs were further analyzed using Database for Annotation, Visualization and Integrated Discovery online software [including gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis]...

Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm that is associated with diminished quality of life, thrombohemorrhagic complications, and transformation to myelofibrosis (MF) and acute leukemia (AML). The important recent discoveries of driver mutations, including the calreticulin gene in addition to JAK2 and MPL, have led to a greater understanding of disease pathogenesis and set the stage for the advent of more sophisticated prognostic, diagnostic, and therapeutic strategies. In this paper we summarize recent studies describing the molecular basis of ET...

Since its approval in 2011, the Janus kinase (JAK) 1/2 inhibitor ruxolitinib has evolved to become the centerpiece of therapy for myelofibrosis (MF), and its use in patients with hydroxyurea resistant/intolerant polycythemia vera (PV) is steadily increasing. A number of other JAK2 inhibitors have entered clinical testing, but none has been approved yet, and many discontinued. Importantly, the activity of these agents is not restricted to patients with JAK2 V617F or exon 12 mutations. Although JAK2 inhibitors provide substantial clinical benefit, their disease-modifying activity is limited, and rational combinations with other targeted agents are needed, particularly in MF, where survival is short...

Myeloproliferative neoplasm is a category in the World Health Organization classification of myeloid tumors. BCR-ABL1-negative MPN is a subcategory that includes primary myelofibrosis (MF), post-essential thrombocythemia MF, and post-polycythemia vera MF. These disorders are characterized by stem cell-derived clonal myeloproliferation. Clinically, these diseases present with anemia and splenomegaly, as well as significant constitutional symptoms, such as severe fatigue, symptoms associated with an enlarged spleen and liver, pruritus, fevers, night sweats, and bone pain...

A significant amount of patients with essential thrombocythemia (ET) complain of symptoms including distal parts of the extremities (e.g., paresthesias or Raynaud's phenomenon). The aim of the present study was to examine peripheral circulation in the upper extremities of individuals with ET. The study included 45 ET patients and 30 control subjects. All participants were subjected to thermography, photoplethysmography, impedance plethysmography, and applanation tonometry pulse wave analysis. The patients with ET differed significantly from the control subjects in terms of 3rd finger skin temperature (mean 31...

Many case reports have indicated the occurrence of monoclonal gammopathy of uncertain significance (MGUS) or multiple myeloma (MM) in patients with Ph-negative myeloproliferative neoplasms (MPN), but few cohorts of patients have been published. This study concerns 667 patients newly diagnosed with polycythemia vera (PV) or essential thrombocythemia (ET) who were tested for monoclonal (M) protein at diagnosis (13.9% of patients). The overall survival of patients with M protein was dramatically lower than that of patients without M protein (12...

We describe here a rare case of a 74-year-old man with essential thrombocythemia who presented an early nonobstructive thrombosis of aortic porcine bioprosthesis complicated by multiple ischemic strokes 14 days after the primary operation. Transesophageal echocardiography on the postoperative day (POD) 17 revealed a mobile, nonobstructive thrombosis inserted on the anterior cusp right of the bioprosthesis. Anticoagulation by intravenous unfractionated heparin was effective with disappearance of the thrombus with good aortic prosthesis function on the POD 20 without requiring reoperation...

Essential thrombocythemia (ET) is a BCL-ABL1-negative myeloproliferative neoplasm. We have reported that increased activated B cells can facilitate platelet production mediated by cytokines regardless JAK2 mutational status in ET. Recently, calreticulin (CALR) mutations were discovered in ~30% JAK2/MPL-unmutated ET and primary myelofibrosis. Here we sought to screen for CALR mutations and to evaluate B cell immune profiles in a cohort of adult Taiwanese ET patients. B cell populations, granulocytes/monocytes membrane-bound B cell-activating factor (mBAFF) levels, B cells toll-like receptor 4 (TLR4) expression and intracellular levels of interleukin (IL)-1β/IL-6 and the expression of CD69, CD80, and CD86 were quantified by flow cytometry...

Activating point mutations in the MPL gene encoding the thrombopoietin receptor are found in 3%-10% of essential thrombocythemia (ET) and myelofibrosis patients. Here, we report the derivation of induced pluripotent stem cells (iPSCs) from an ET patient with a heterozygous MPL V501L mutation. Peripheral blood CD34(+) progenitor cells were reprogrammed by transient plasmid expression of OCT4, SOX2, KLF4, c-MYC plus BCL2L1 (BCL-xL) genes. The derived line M494 carries a MPL V501L mutation, displays typical iPSC morphology and characteristics, are pluripotent and karyotypically normal...
