摘要

必需血小板血症(ET)的临床表现可能与早期/预纤维化原发性骨髓纤维化(PRE-PMF)非常相似,尤其是在PROD-PMF中呈现血小板症(PRED-PMF-T),但可能与不同的结果有关。区分这两个实体非常重要。这项研究的目的是解决将PRMF-T与ET的临床和预后相关性解决的临床和预后相关性,其中包括ET的258例ET和PRE-PMF-T的105,接受JAK2V617F,MPL(Exon 10)和Calr(外显子9)和较高的preem and pre ant pre Mutants and pre Mutants ant pre Mutants ant pre mutant.pmft-pmpf-pmft-pmft-pmft-ptt-p.pt-ptt-pateations and Calr(Exon 9)突变。白细胞和血小板计数,但血红蛋白水平低于ET患者。与ET患者相比,PRE-PMF-T患者的总体总体,无白血病和无血栓形成生存率较短。 ET患者的脑缺血性中风率较高,而PMF-T前患者患有斑点头静脉血栓形成。 JAK2V617F,CALR和MPL突变以及Calr等位基因负担的频率没有什么不同,但是PRE-PMF-T的JAK2V617F等位基因负担明显更高。患有JAK2V617F突变的PRE-PMF-T患者的总生存率较低,无血栓形成无生存期,而驱动基因突变的状态并不影响ET.ET和PMF-T前患者的结果,PMF-T是两个不同的疾病实体,并且表现出不同的临床表型,基因型,基因型和成果。

Abstract

The clinical presentations of essential thrombocythemia (ET) may be quite similar to early/prefibrotic primary myelofibrosis (pre-PMF), especially in pre-PMF presenting with thrombocytosis (pre-PMF-T), but may be associated with a different outcome. It is very important to distinguish these two entities. The aim of this study was to address the clinical and prognostic relevance of distinguishing pre-PMF-T from ET.All patients, including 258 with ET and 105 with pre-PMF-T, received JAK2V617F, MPL (exon 10), and CALR (exon 9) mutation analysis and allele burden measurement for JAK2V617F and CALR mutants.Patients with pre-PMF-T had an older age and higher leukocyte and platelet counts but lower hemoglobin levels than patients with ET. Patients with pre-PMF-T had a shorter overall, leukemia-free, and thrombosis-free survival compared with patients with ET. Patients with ET had a higher rate of cerebral ischemic stroke, whereas patients with pre-PMF-T tended to have splanchnic vein thrombosis. The frequencies of JAK2V617F, CALR, and MPL mutations and CALR allele burden were no different, but JAK2V617F allele burden was significantly higher in pre-PMF-T. Patients with pre-PMF-T with the JAK2V617F mutation had an inferior overall survival and thrombosis-free survival, whereas the status of driver gene mutations did not influence the outcomes of patients with ET.ET and pre-PMF-T were two distinct disease entities and exhibited different clinical phenotype, genotype, and outcomes.
