AbstractBackground Patients with haematological malignancies are at high risk of invasive fungal infections. However, there is a lack of information about the utilisation of the recommended Australian antifungal prophylaxis guidelines in haematology outpatients.Objective To assess the impact of a weekly pharmacist review of high-risk adult haematology outpatients on the utilisation of appropriate antifungal prophylaxis.Setting Outpatient cancer centre, tertiary referral hospital in Sydney, Australia.Method A 3-month pre-and post-interventional study was conducted. A retrospective audit was conducted to obtain baseline util...

Authors: Liu L, Liu X, Sun Y, Zeng Y, Tang X, Li X, Liu J, Xiao R Abstract Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors, and has high incidence and mortality rates, worldwide. Myelodysplastic syndrome (MDS), a disorder of hematopoietic stem or progenitor cells, results in marrow failure, which increases the risk of acute myeloid leukemia (AML). Few studies had reported patients who have suffered from both ESCC and MDS/AML simultaneously. To identify possible potential associations between ESCC and MDS/AML, the present case report describes a patient with both types of these t...

We present long-term safety data for niraparib from the ENGOT-OV16/NOVA trial. METHODS: This multicenter, double-blind, randomized, controlled phase III trial evaluated the efficacy and safety of niraparib for the treatment of recurrent ovarian cancer. Patients were randomly assigned 2:1 to receive either once-daily niraparib 300 mg or placebo. Two independent cohorts were enrolled based on germline BRCA mutation status. The primary endpoint was progression-free survival, reported previously. Long-term safety data were from the most recent data cutoff (September 2017). RESULTS: Overall, 367 patients received...

(University of Texas M. D. Anderson Cancer Center) The University of Texas MD Anderson Cancer Center and Astex Pharmaceuticals, Inc., a wholly owned subsidiary of Otsuka Pharmaceutical Co. Ltd., based in Tokyo, Japan, today announce a strategic collaboration agreement aimed at accelerating the clinical evaluation of Astex's pipeline of products for patients with certain types of leukemia, including myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML) and acute myeloid leukemia (AML). The collaboration will combine MD Anderson's clinical trials infrastructure and expertise with Astex's clinical pipeline products.

esco Albano Immunomodulatory drugs (IMiDs) are analogs of thalidomide. They have immunomodulatory, antiangiogenic and proapoptotic properties and exert a role in regulating the tumor microenvironment. Recently IMiDs have been investigated for their pleiotropic properties and their therapeutic applications in both solid tumors (melanoma, prostate carcinoma and differentiated thyroid cancer) and hematological malignancies. Nowadays, they are applied in de novo and relapsed/refractory multiple myeloma, in myelodysplastic syndrome, in del5q syndrome with specific use of lenalidomide and B-cell lymphoma. Several studies hav...

This study was designed in order to identify the prognostic relevance of CD200 expression and soluble Cytotoxic T-lymphocyte antigen-4 (CTLA-4) levels in myelodysplastic syndrome (MDS) patients. METHODS: The study included 57 MDS (37 intermediate and 20 high risk) patients and 10 controls. For all of included patients; CD200 expression was identified by flowcytometry on CD33 positive cells and soluble CTLA-4 (CD152) concentration was determined by ELISA. RESULTS: CD200 positive expression was detected in 32/57 (56.1%) of MDS cases, the mean serum CTLA-4 concentrations were significantly higher in MDS patients as co...

elosi Acute myeloid leukemia (AML) is a heterogeneous disease generated by the acquisition of multiple genetic and epigenetic aberrations which impair the proliferation and differentiation of hematopoietic progenitors and precursors. In the last years, there has been a dramatic improvement in the understanding of the molecular alterations driving cellular signaling and biochemical changes determining the survival advantage, stimulation of proliferation, and impairment of cellular differentiation of leukemic cells. These molecular alterations influence clinical outcomes and provide potential targets for drug development...

Abstract The tumor suppressor p53 exerts pivotal roles in hematopoietic stem cell (HSC) homeostasis. Mutations of the TP53 gene have recently been described in individuals with clonal hematopoieis conferring substantial risk of developing blood cancers. In patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), TP53 aberrations - mutations, deletions and a combination thereof - are encountered at a constant frequency of approximately 10%. These aberrations affect HSCs transforming them into preleukemic stem cells, pinpointing their central role in leukemogenesis. AML and MDS with TP53 aberr...

Kobbe Thomas Schroeder To provide long-term outcome data and predictors for response and survival, we retrospectively analyzed all 151 patients with relapse of myeloid neoplasms after allogeneic hematopoietic stem cell transplantation (allo-HSCT) who were uniformly treated with first-line azacitidine (Aza) salvage therapy at our center. Patients were treated for molecular (39%) or hematologic relapse (61%), with a median of 5 cycles of Aza and at least one donor lymphocyte infusion in 70% of patients. Overall response was 46%, with 41% achieving complete (CR) and 5% achieving partial remission. CR was achieved after ...
