BACKGROUND LMO2 is highly expressed at the most immature stages of lymphopoiesis. In T-lymphocytes, aberrant LMO2 expression beyond those stages leads to T-cell acute lymphoblastic leukemia, while in B cells LMO2 is also expressed in germinal center lymphocytes and diffuse large B-cell lymphomas, where it predicts better clinical outcome. The implication of LMO2 in B-cell acute lymphoblastic le...

Objective: To describe certain characteristics of acute leukemia regarding age, gender, cytomorphology and immunophenotype at King Hussein Medical Center. Methods: A retrospective review of bone marrow aspirate and/or biopsy reports was conducted at Princess Iman Research and Laboratory Sciences Center at King Hussein Medical Center during the period between Jan 2004 and Dec 2008. A total of 22...

BACKGROUND Despite incremental improvements in outcomes for patients with acute lymphoblastic leukemia, significant numbers of patients still die from this disease. Mammalian target of rapamycin inhibitors have shown potential in vitro and in vivo as therapeutic agents against a range of tumors including acute lymphoblastic leukemia. DESIGN AND METHODS Flow cytometry was used to evaluate drug...

back ground: vincristine (vcr), is a chemotherapy drug, useful in the treatment of leukemia, lymphoma and solid tumor and it is a potent neurotoxin and sensory neuropathy drug which a common behavioral toxicity of this drug. neuropathy is common squeal of intensive chemotherapy protocols that contain vincristine and corticosteroids. materials and methods: this study was a retrospective and desc...

background: the frequency of the multi-drug resistance 1 (mdr1) gene c3435t polymorphism differs in various ethnical populations such as asian, african, and caucasians populations. a silent c3435t polymorphism in exon 26 of mdr1 has been reported to be associated with a decreased expression of p-gp in tt genotypes carriers compared with cc genotypes carriers. materials and methods: to evaluate ...

background: the aim of this study was to detect the prognostic significance of survivin level and the expression of total p53 in acute lymphoblastic leukemia (all) and its correlation to patients' outcome. methods: sixty two children newly diagnosed with acute lymphoblastic leukemia were treated with chemotherapy and followed up for 2 years or until death. twenty apparently healthy volunteers w...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or apoptosis can be induced by variety of agents. despite advances in the treatment of acute lymphoblastic leukemia (all), in most patients long-term survival rates remain unsatisfactory, especially in t-cell derived all. thus we studied the anti-can...

Acute lymphoblastic leukemia (ALL) has several clinical manifestations on the base of bone marrow infiltration and the extent of extra medullary involvement. Anterior chest wall bulging as an initial presentation is rare. The aim of this case report study is to present a 3.5 year-old-boy presented with anterior chest wall bulging without history of trauma since 1 month ago. Tc99m-MDP bone scan ...

ALL: acute lymphoblastic leukemia INTRODUCTION Blinatumomab is the first-in-class bispecific T-cell engager antibody approved for the treatment of refractory acute lymphoblastic leukemia (ALL). It simultaneously binds endogenous CD3 cytotoxic T cells and CD19 B cells, resulting in T-celle mediated serial lysis of normal and malignant B cells. Although studies have been conducted into the incide...
