Myelodysplastic Syndromes

Patients with myelodysplastic syndrome undergoing a reduced–intensity conditioning regimen prior to allogeneic stem-cell transplantation had similar 2-year survival outcomes as patients who underwent myeloablative conditioning.

This video explores the current treatment landscape for lower-risk MDS patients, including the various agents and sequencing strategies employed to best optimize outcomes.

The use of the thrombopoietin receptor agonist eltrombopag was clinically effective at raising platelet counts in patients with lower-risk myelodysplastic syndromes with severe thrombocytopenia.

This look ahead at hematologic malignancies in 2017 focuses on new agents being studied for the treatment of acute leukemias, myelodysplastic syndromes, and chronic lymphocytic leukemia.

This video examines different mutational profiles of therapy-related myeloid neoplasms and how they can affect approaches to treatment.

Patients with AML or MDS with unfavorable risk cytogenetic profiles, TP53 mutations, or both had good clinical response and robust mutation clearance with decitabine.

A scoring system including several patient characteristics was found to have significant prognostic value for patients with myelodysplastic syndromes undergoing allogeneic hematopoietic cell transplantation.

Adding the HDAC inhibitor valproic acid to decitabine did not improve outcomes in patients with myelodysplastic syndromes or acute myeloid leukemia.

Myelodysplastic syndromes, also referred to collectively as MDS, have significant biological and clinical heterogeneity, a highly variable natural history, and a complex pathobiology that is not clearly understood.

The myelodysplastic syndromes (MDS) are a heterogeneous spectrum of clonal hematopoietic diseases characterized by bone marrow hypercellularity, dysplasia of cellular elements, and consequent inadequate hematopoiesis, with resultant peripheral blood cytopenias.

The review by Dr. Akhtari outlines the diagnosis, prognosis, and treatment options for patients with myelodysplastic syndromes (MDS), and touches on the current challenges in treating patients suffering from MDS.

There's reason to question whether lenalidomide is the cause of secondary cancers in patients who take it as an adjuvant. But new scrutiny may help to clarify how it acts against the primary.

For years, chemotherapy-associated myelosuppression has represented a major limitation to a patient’s tolerance of anticancer therapy. In addition, the clinical consequences of chemotherapy-induced myelosuppression (such as febrile neutropenia, dose reductions, or lengthy dose delays) may have had significant negative effects on quality of life or even response to treatment.

Our case illustrates the fact that MDS-associated GS can be treated palliatively with radiation and hypomethylating agents in an appropriate setting. With the growing geriatric patient population, effective treatment options are needed in this disease.

While reduced-intensity conditioning allows hematopoietic stem cell transplant (HSCT) in older cancer patients who cannot tolerate standard conditioning regimens, only about one-third of such patients have an HLA-matched related donor available. For these patients, stem cells derived from unrelated umbilical cord blood (UCB) may provide a suitable and convenient alternative

Studies presented at the 2007 San Antonio Breast Cancer Symposium raise new questions about the role of anthracycline-based regimens as adjuvant therapy in early breast cancer, suggesting that these regimens may be appropriate only for a small subset of patients.

An HLA-A2-restricted peptide vaccine given as salvage therapy to patients with acute myeloid leukemia or myelodysplastic syndrome showed evidence of immunological, molecular, and clinical efficacy

In a phase II trial of diffuse large B cell lymphoma (DLBCL) patients with high-risk or relapsed chemosensitive disease, the combination of the radioimmunotherapy (RIT) agent 131I tositumomab (Bexxar) plus BEAM chemotherapy proved safe as an outpatient preparative regimen for autologous peripheral blood stem cell transplant (PSCT)

New updated results from a pivotal phase II trial evaluating lenalidomide (Revlimid) in patients with myelodysplastic syndromes (MDS)

IV Vidaza Approved; Oral Formulation to Be Tested

Two clinical studies with a total of 1,202 patients have found posaconazole (Noxafil) significantly more effective than two other antifungal agents in preventing fatal invasive fungal infections in acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) patients who develop neutropenia as a result of chemotherapy

The US Food and Drug Administration (FDA) has approved Schering-Plough Corporation's Noxafil (posaconazole) Oral Suspension for the prevention of invasive Aspergillus and Candida infections in patients age 13 years and older at high risk of developing these infections.

The Food and Drug Administration (FDA) has approved the marketing of Dacogen (decitabine for injection, MGI Pharma) for the treatment of all forms of myelodysplastic syndrome (MDS). The agency acted after reviewing data submitted by the sponsor from a pivotal phase III trial, in which patients evaluable for response had a 21% overall response rate, and two supporting studies.

In a phase III trial, posaconazole (Noxafil Oral Suspension), an investigational broad-spectrum triazole antifungal, significantly reduced the incidence of serious invasive fungal infections (IFIs) and of aspergillosis, and demonstrated a survival benefit, compared with standard azole antifungal treatment in high-risk neutropenic patients undergoing intensive chemotherapy.
