Hematologic malignancies of childhood comprise the most common childhood cancers. These neoplasms derive from the pathologic clonal expansion of an abnormal cancer-initiating cell and span a diverse spectrum of phenotypes, including acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), myeloproliferative neoplasms (MPN), and myelodysplastic syndromes (MDS). Expansion of immature lym...
Myelodysplastic syndromes (MDS) are clonal myeloid disorders characterized by progressive peripheral blood cytopenias associated with ineffective myelopoiesis. They are typically considered neoplasms because of frequent genetic aberrations and patient-limited survival with progression to acute myeloid leukemia (AML) or death related to the consequences of bone marrow failure including infection...
BACKGROUND The molecular causes of many hematologic cancers remain unclear. Among these cancers are chronic neutrophilic leukemia (CNL) and atypical (BCR-ABL1-negative) chronic myeloid leukemia (CML), both of which are diagnosed on the basis of neoplastic expansion of granulocytic cells and exclusion of genetic drivers that are known to occur in other myeloproliferative neoplasms and myeloproli...
INTRODUCTION The effectiveness of a screening strategy for the detection of a hepatitis B virus (HBV) infection followed by prophylaxis in order to prevent HBV reactivation was assessed in patients with hematologic neoplasms. MATERIAL AND METHODS A decision tree was developed to compare the cost and effectiveness (prevented reactivations) over an 18 month period of a screening strategy prior ...
PURPOSE The aim of this study was to define the risk of second cancer in nongastric marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT). EXPERIMENTAL DESIGN We considered for the analysis 157 patients with a confirmed histology of marginal zone B-cell lymphoma of MALT, presenting with a clinically prevalent extranodal site of disease, except for stomach. All patients came from...
spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
as the data on the epidemiology and outcome of fungal infections in children with hematologic cancer are limited especially in iran, this study was aimed to delineate the epidemiologic features and outcome of fungal infections in this population. the medical records of all children with hematologic malignancies diagnosed with a fungal infection from 2005 to 2010 at a tertiary pediatric hospital...
The diagnosis of any genetic predisposition to malignancy carries profound significance for the patient and family, with implications clinical management that differ from when there is no identifiable heritable cause. presence a develop hematologic neoplasms under-recognized. Therefore, such was added as separate in diagnostic World Health Organization classification 2016. Such may occur absenc...
