Neutropenia and infection are major dose-limiting side effects of chemotherapy. The risk of initial infection and subsequent complications are directly related to the depth and duration of neutropenia. Recent genome-wide association studies identified variants in DARC and CXCL2 genes, and in ORMDL3-GSDMA-CSF3 locus on chromosome 17q21 that influence white blood cell and neutrophil counts in healthy individuals. To investigate whether polymorphisms in these loci in conjunction with chemotherapy may modulate risk of treatment complications, we analyzed 21 SNPs across these genes for an association with chemotherapy-related neutropenia and infection in 286 Caucasian children with acute lymphoblastic leukemia...

BACKGROUND: In patients with acquired aplastic anemia, destruction of hematopoietic cells by the immune system leads to pancytopenia. Patients have a response to immunosuppressive therapy, but myelodysplastic syndromes and acute myeloid leukemia develop in about 15% of the patients, usually many months to years after the diagnosis of aplastic anemia. METHODS: We performed next-generation sequencing and array-based karyotyping using 668 blood samples obtained from 439 patients with aplastic anemia...

Kumanan Wilson and colleagues explain how the rapid response to XMRV as a novel pathogen has highlighted some challenges pertaining to policy-making and editorial responsibilities. The impact on policy and the propagation of the initial scientific information may not cease if the evidence is disproven and retracted from the peer-reviewed literature, which creates a challenge for regulators and scientific journals. Please see later in the article for the Editors' Summary.

BACKGROUND: Autologous hematopoietic stem cell (HSC) transplantation is used to facilitate hematopoietic recovery after administration of high-dose chemotherapy in patients with Hodgkin's disease, non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), leukemias, and some solid tumors. There are limitations to the existing methods of mobilizing CD34+ HSC with chemotherapy and/or granulocyte colony-stimulating factor (G-CSF). Plerixafor, a bicyclam molecule that acts as a pure antagonist of chemokine receptor-4, is approved by the US Food and Drug Administration for use in combination with G-CSF for mobilization of CD34+ HSC in patients with NHL or MM...

This article recounts the development of the American Society of Clinical Oncology (ASCO) and explores the role of its members in defining oncology's boundaries-boundaries dictated by scientific innovations, major changes in the structure of medical specialization, and the competing efforts of closely related professional groups. Oral histories, journal articles, and unpublished materials from the ASCO History of Oncology Archive were reviewed to analyze these events closely. In 1972, the American Board of Internal Medicine recognized medical oncology as a subspecialty, creating tensions between oncology and hematology as each discipline defended its identity...

Recent regulatory changes have placed a major emphasis on in vitro safety testing and alternative models. In regard to skin sensitization tests, dendritic cells (DCs) derived from human peripheral blood have been considered in the development of new in vitro alternatives. Human cell lines have been also reported recently. In our previous study, we suggested that measuring CD86 and/or CD54 expression on THP-1 cells (human monocytic leukemia cell line) could be used as an in vitro skin sensitization method. An inter-laboratory study among two laboratories was undertaken in Japan in order to further develop an in vitro skin sensitization model...

RNA interference (RNAi) is a conserved biologic response to double-stranded RNA that results in the sequence-specific silencing of target gene expression. Over the past 5 years, an intensive research effort has facilitated the rapid movement of RNAi from a relatively obscure biologic phenomenon to a valuable tool used to silence target gene expression and perform large-scale functional genomic screens. In fact, recent studies reported in this journal and others have demonstrated success using RNAi to address the role of oncogene expression in leukemia cell lines and to validate the therapeutic potential of RNAi for treating these blood disorders...

PURPOSE/OBJECTIVES: To provide an overview of childhood acute lymphoblastic leukemia (ALL), including epidemiology, clinical presentation, diagnostic classification, prognostic factors, current treatment, long-term sequelae, and nursing management. DATA SOURCES: Journal articles, books, and clinical experience. DATA SYNTHESIS: Childhood ALL is a heterogeneous disorder, and current treatment is tailored to risk factors (e.g., initial white blood count, cytogenetic properties of the leukemic blasts)...

OBJECTIVE: Polyploidy, the state of having greater than the diploid content of DNA, has been recognized in a variety cells. Among these cell types, the megakaryocytes are classified as obligate polyploid cells, developing a polyploid DNA content regularly during the normal life cycle of the organism, while other cells may become polyploid only in response to certain stimuli. The objective of this review is to briefly describe the different cell cycle alterations that may lead to high ploidy, while focusing on the megakaryocyte and the importance of high ploidy to platelet level and function...

BACKGROUND AND OBJECTIVE: The diagnosis of myelodysplastic syndromes (MDS) is essentially morphological and based on the presence of dysplastic features in the peripheral blood and bone marrow. The French-American-British (FAB) Cooperative Group proposed a classification based on easily obtainable laboratory information. In spite of some limitations, the FAB criteria have been useful for a long time. Currently, the recognition of other distinct morphological MDS subgroups such as hypocellular MDS and MDS with myelofibrosis, the increasing incidence of MDS in children as well as that of therapy-related MDS, and the finding of specific chromosomal alterations associated with different morphological features, reveal the insufficiency of this classification...
