rs2431697, a Polymorphism of Mir-146a, Is a Precozing Marker of Progression to Secondary Myelofibrosis: New Epigenetic Regulation of Jak/Stat3 Signaling
Abstract Introduction: Transformation to secondary myelofibrosis (MF) occurs as part of the natural history of polycythemia vera (PV) and essential thrombocythemia (ET), the two more indolent Ph-negative myeloproliferative neoplasms (MPN). Once transformed, survival is remarkably shorted. Chronic inflammation plays a critical role in the progression of MPN, driving clonal expansion toward end stage disease. Importantly, MPN are characterized by the production of inflammatory cytokines, by both malignant and non-malignant clone. Inflammation and cancer share a common pathway, i.e. NF-κB. Interestingly, miR-146a regulates TLR/NF-κB pathway through the inhibition of its targets, IRAK1 and TRAF…
Feasibility of Treatment Discontinuation in Chronic Myeloid Leukemia in Clinical Practice in Spain: Results from a Nationwide Series of 236 Patients
Abstract Introduction: Over half of patients with chronic myeloid leukemia (CML) in sustained deep molecular remission do not lose the major molecular response (MMR) after stopping treatment with tyrosine kinase inhibitors (TKI). This strategy is safe in controlled clinical trials, but there is scarce information on its applicability in the real-life setting. We aimed to assess if treatment cessation was feasible in clinical practice in a large nationwide series of CML patients from Spain. Methods: This retrospective study comprised a series of 236 patients in chronic-phase CML who discontinued TKI treatment outside of clinical trials between April 2009 and February 2018 in 33 Spanish insti…
Excess Mortality in Polycythemia Vera and Essential Thrombocythemia
Abstract Background and objective. An important proportion of patients with polycythemia vera (PV) and essential thrombocythemia (ET) are diagnosed in the seventh and eighth decades of life. Because of the chronic course of PV and ET and the advanced age of patients, many will actually die from age-related ailments instead of the myeloproliferative neoplasm, so the disease's impact on life-expectancy remains largely unknown. This registry‐based study was aimed at investigating the excess mortality attributable to PV and ET in a large series of patients diagnosed and managed according to modern criteria. Methods. We queried the databases of the Spanish Group for Chronic Myeloproliferative Ne…
