The 2008 revision of the World Health Organization (WHO) classification of myeloid neoplasms and acute leukemia: rationale and important changes.
The classification of myeloid neoplasms and acute leukemia is highlighted with the aim of familiarizing hematologists, clinical scientists, and hematopathologists not only with the major changes in the classification but also with the rationale for those changes. Expand
Activating mutation in the tyrosine kinase JAK2 in polycythemia vera, essential thrombocythemia, and myeloid metaplasia with myelofibrosis.
High-throughput DNA resequencing identified a recurrent somatic missense mutation JAK2V617F in granulocyte DNA samples of 121 of 164 PV patients, of which 41 had homozygous and 80 had heterozygous mutations. Expand
A tyrosine kinase created by fusion of the PDGFRA and FIP1L1 genes as a therapeutic target of imatinib in idiopathic hypereosinophilic syndrome.

- The New England journal of medicine
- 27 March 2003
The acquisition of a T674I resistance mutation at the time of relapse demonstrates that FIP1L1-PDGFRalpha is the target of imatinib, and data indicate that the deletion of genetic material may result in gain-of-function fusion proteins. Expand
New prognostic scoring system for primary myelofibrosis based on a study of the International Working Group for Myelofibrosis Research and Treatment.
In 409 patients with assessable metaphases, cytogenetic abnormalities were associated with shorter survival, but their independent contribution to prognosis was restricted to patients in the intermediate-risk groups. Expand
MPL515 mutations in myeloproliferative and other myeloid disorders: a study of 1182 patients.
Recently, a gain-of-function MPL mutation, MPLW515L, was described in patients with JAK2V617F-negative myelofibrosis with myeloid metaplasia (MMM). To gain more information on mutational frequency,… Expand
Mutation in TET2 in myeloid cancers.
It is difficult to assign a specific role in the pathogenesis or progression of myeloproliferative neoplasms to mutant TET2, and it is suggested that a role for TET1 in disease progression is suggested. Expand
Proposals and rationale for revision of the World Health Organization diagnostic criteria for polycythemia vera, essential thrombocythemia, and primary myelofibrosis: recommendations from an ad hoc…
The Janus kinase 2 mutation, JAK2617V>F, is myeloid neoplasm-specific; its presence excludes secondary polycythemia, thrombocytosis, or bone marrow fibrosis from other causes. Furthermore, JAK2617V>F… Expand
DIPSS plus: a refined Dynamic International Prognostic Scoring System for primary myelofibrosis that incorporates prognostic information from karyotype, platelet count, and transfusion status.
- N. Gangat, D. Caramazza, +10 authors A. Tefferi
- Journal of clinical oncology : official journal…
- 1 February 2011
DPSS plus effectively combines prognostic information from DIPSS, karyotype, platelet count, and transfusion status to predict overall survival in PMF and predicts inferior leukemia-free survival. Expand
Safety and efficacy of INCB018424, a JAK1 and JAK2 inhibitor, in myelofibrosis.
- S. Verstovsek, H. Kantarjian, +10 authors A. Tefferi
- The New England journal of medicine
- 15 September 2010
INCB018424 was associated with marked and durable clinical benefits in patients with myelofibrosis for whom no approved therapies existed, and clinical benefits were associated with a marked diminution of levels of circulating inflammatory cytokines that are commonly elevated in myel ofibrosis. Expand
Role of JAK2 in the pathogenesis and therapy of myeloproliferative disorders
- R. Levine, A. Pardanani, A. Tefferi, D. Gilliland
- Biology, Medicine
- Nature Reviews Cancer
- 1 September 2007
The discoveries of JAK2V617F have changed the landscape for diagnosis and classification of PV, ET and PMF, and show the ability of genomic technologies to identify new molecular targets in human malignancies with pathogenetic, diagnostic and therapeutic significance. Expand
