Pracinostat for AML update: follow-up analysis and Phase III trial

Pracinostat is a histone deacetylase (HDAC) inhibitor that has demonstrated very promising efficacy in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Here, Guillermo Garcia-Manero, ... Author: VJHemOnc Added: 01/08/2018

Background: Therapeutic drug monitoring (TDM) of posaconazole is usually performed 1 week after starting the drug because of its long half-life. However, previous studies showed that measuring the posaconazole plasma concentration (PPC) on day 3 is effective for predicting steady-state levels. The purpose of this study was to evaluate the relevance of early TDM (day 3) of posaconazole for achieving an optimal PPC. Methods: This prospective study was conducted from September 2014 to August 2016. A total of 148 patients with acute myeloid leukemia or myelodysplastic syndromes received a 200 mg posaconazole oral suspensi...

Authors: Nenova I, Grudeva-Popova J Abstract The growing number of successfully cured cancer patients has created a new field in oncogenesis. The life expectancy of such patients has increased, however this favorable event may create enough time for epigenetic events to occur which can cause a new carcinognic event, i.e. a secondary malignancy. The terms in use are second primary malignancies as well as therapy-related neoplasms in case the treatment of the first neoplasm is a direct cause. Second primary malignancies can be hematological neoplasms or solid tumors, with solid tumors having higher frequency. Hematol...

, Khandanpour C, no Abstract Differentiation of haematopoietic stem cells is regulated by a concert of different transcription factors. Disturbed transcription factors function can be the basis of (pre)malignancies such as myelodysplastic syndrome or acute myeloid leukaemia. Growth factor independence 1b is a repressing transcription factor regulating quiescence of hematopoietic stem cellss and differentiation of erythrocytes and platelets. Here, we show that low expression of Growth factor independence 1b in blast cells is associated with an inferior prognosis of myelodysplastic syndrome and acute myeloid leukaem...

AbstractThe prognostic value of peripheral blasts (PB) is not well-studied in patients with myelodysplastic syndromes (MDS). We evaluated the impact of PB on overall survival (OS) and transformation to acute myeloid leukemia (AML) in a large cohort. The MDS database at the Moffitt Cancer Center was retrospectively reviewed to identify patients with ≥ 1% PB (PB-MDS) and those without PB (BM-MDS). We also assessed the correlation between PB and gene mutations. One thousand seven hundred fifty-eight patients were identified, among whom 13% had PB near the time of diagnosis. PB-MDS patients were more likely to be you...

AbstractIn contrast to the evidence regarding azacitidine (Aza), there is limited knowledge about the combination of decitabine (DAC) and donor lymphocyte infusions as salvage therapy for relapse after allogeneic stem cell transplantation (allo-SCT) so far. We retrospectively analyzed data of 36 patients with hematological (n = 35) or molecular relapse (n = 1) of acute myeloid leukemia (AML,n = 29) or myelodysplastic syndrome (MDS,n = 7) collected from 6 German transplant centers. Patients were treated with a median of 2 cycles DAC (range, 1 to 11). DAC was the first ...

Abstract UHMK1 (KIS) is a nuclear serine/threonine kinase that possesses a U2AF homology motif and phosphorylates and regulates the activity of the splicing factors SF1 and SF3b155. Mutations in these components of the spliceosome machinery have been recently implicated in leukemogenesis. The fact that UHMK1 regulates these factors suggests that UHMK1 might be involved in RNA processing and perhaps leukemogenesis. Here we analyzed UHMK1 expression in normal hematopoietic and leukemic cells as well as its function in leukemia cell line. In the normal hematopoietic compartment, markedly higher levels of transcripts ...

Myelodysplastic syndrome (MDS) is a heterogeneous hematological malignancy, characterized by cytopenia and accompanied by a risk of transformation into acute myeloid leukemia (AML). Epidemiological studies for decades have shown association between autoimmune diseases (AIDs) and MDS. Specifically, patients with antecedent AIDs tends to have an increased risk of developing MDS, and these patients display different clinical characteristics and outcomes. Importantly, immune dysregulation has been the common driving force between MDS and AIDs pathogenesis.

Publication date: Available online 29 December 2017 Source:Journal of Geriatric Oncology Author(s): Marlise R. Luskin, Gregory A. Abel The myelodysplastic syndromes (MDS) are a varied group of hematologic neoplasms that lead to bone marrow failure, and also carry a risk of progression to acute myeloid leukemia. Patients with MDS suffer significant impairments to both their quality of life and survival. Age is the dominant risk factor for the development of MDS, with a median age at diagnosis over 70years. Consequently, patients with MDS frequently have concurrent comorbidities and/or frailty which may be coincident or rel...
