The presence of cytogenetic aberrations on mesenchymal stem cells (MSC) from myelodysplastic syndrome (MDS) patients is controversial. The aim of the study is to characterize bone marrow (BM) derived MSC from patients with MDS using: kinetic studies, immunophenotyping, fluorescent in situ hybridization (FISH) and genetic changes by array-based comparative(More)
BACKGROUND AND OBJECTIVES The optimal post-remission therapy for adults with high-risk acute lymphoblastic leukemia (ALL) is not well established. This multicenter randomized trial by the Spanish PETHEMA Group was addressed to compare three options of post-remission therapy in adults with high-risk ALL: chemotherapy, allogeneic stem cell transplantation(More)
BACKGROUND AND OBJECTIVES Cytogenetic analysis is one of the most reliable prognostic factors in acute lymphoblastic leukemia. The objective of this study was to analyze the prognostic value of cytogenetic analysis in children and adults with high-risk acute lymphoblastic leukemia (HR-ALL) included in a prospective multicenter trial. DESIGN AND METHODS(More)
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare disease that currently lacks genomic and genetic biomarkers to assist in its clinical management. We performed whole-exome sequencing (WES) of three BPDCN cases. Based on these data, we designed a resequencing approach to identify mutations in 38 selected genes in 25 BPDCN samples. WES(More)
Recently, an acute restriction of imiglucerase has occurred as a result of viral contamination and manufacturing problems. A position statement from the European Working Group for Gaucher Disease and European Gaucher Alliance established a set of key recommendations for identifying and monitoring at-risk patients. In Spain, a profile of the shortage(More)
Chronic lymphocytic leukaemia (CLL) is a frequent disease in which the genetic alterations determining the clinicobiological behaviour are not fully understood. Here we describe a comprehensive evaluation of the genomic landscape of 452 CLL cases and 54 patients with monoclonal B-lymphocytosis, a precursor disorder. We extend the number of CLL driver(More)
BACKGROUND It has been recognized that cure is possible for human immunodeficiency virus (HIV)-infected patients with Burkitt lymphoma/leukemia (BL) if appropriate chemotherapy is used. The introduction of rituximab in BL therapeutic schemes has been scarcely explored. The outcome and toxicity of HIV-positive patients with BL treated in a rituximab and(More)
BACKGROUND Treatment of central nervous system relapse in adult acute lymphoblastic leukemia is a challenge and outcome is poor. Liposomal cytarabine has a prolonged half-life and, given intrathecally, has produced high response rates in patients with central nervous system relapse of non-Hodgkin's lymphoma. The aim of this study was to evaluate the(More)
BACKGROUND AND OBJECTIVE Rapid identification of AML patients carrying the t(15;17) translocation for treatment decision-making is currently made on the basis of morphologic screening. However, the existence of both false positives and negatives highlights the need for more objective methods of screening AML cases and further molecular confirmation of the(More)
Recurrence of acute lymphoblastic leukemia (ALL) in the central nervous system (CNS) confers a poor prognosis, although to the authors' knowledge, only a few studies have analyzed this issue in adults. For the current study, the authors analyzed the frequency, predictive factors, and prognosis of CNS involvement and recurrence in adult patients with ALL who(More)
