BACKGROUND Little is known about the potential risk factors for infant leukemia. With its very young age at diagnosis, exposures occurring in the perinatal period are suspected. Parental infertility and infertility treatment have been studied with regard to childhood cancer in general, but rarely in individual cancer subtypes. METHODS A case-control study of infant leukemia was conducted thro...

Three distinct immature T-cell acute lymphoblastic leukemia entities have been described including cases that express an early T-cell precursor immunophenotype or expression profile, immature MEF2C-dysregulated T-cell acute lymphoblastic leukemia cluster cases based on gene expression analysis (immature cluster) and cases that retain non-rearranged TRG@ loci. Early T-cell precursor acute lympho...

INTRODUCTION Acute lymphoblastic leukemia (ALL) is disease of lymphoid precursors and is the most common cancer. Diagnosis of ALL is made by evaluating morphology and flowcytometric Immunophenotyping (FCI)and is an important adjunct in diagnosis and determining treatment in ALL, with availability of extensive monoclonal antibodies in the recent years there is tremendous progress in the field of...

background: acute lymphoblastic leukemia is a lymphoid malignancy, resulting from autonomous proliferation of monoclonal abnormal stem cell. the aim of this study was to evaluate the response rate and prognostic factor of adult patients suffering from acute lymphoblastic leukemia, who were treated with chemotherapy in south east of iran and demographic methods were used for this study.   method...

background: oral manifestations are frequently the initial signs of acute leukemia, prompting the patient to consult the dentist first. the gingival tissue is one site commonly involved either by leukemic infiltration or by inflammatory reactive hyperplasia, causing gingival enlargement. the gingival infiltration may also be present without gingival enlargement. early recognition of clinical fi...

Background: The purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. Patients and Methods: This was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the ...

Although childhood acute lymphoblastic leukemia is the most common pediatric cancer, its etiology remains poorly understood. In an attempt to replicate the findings of 2 recent genome-wide association studies in a French-Canadian cohort, we confirmed the association of 5 SNPs [rs7073837 (P=4.2 x 10(-4)), rs10994982 (P=3.8 x 10(-4)), rs10740055 (P=1.6 x 10(-5)), rs10821936 (P=1.7 x 10(-7)) and r...

In contrast to acute lymphoblastic leukemia in children, adult cases of this disease are associated with a very poor prognosis. In order to ascertain whether the frequencies and patterns of submicroscopic changes, identifiable with single nucleotide polymorphism array analysis, differ between childhood and adult acute lymphoblastic leukemia, we performed single nucleotide polymorphism array ana...

acute lymphoblastic leukemia (all) is the most common form of childhood cancer representing 80-85% of all leukemia. we describe a 3 years old girl with pain, swelling and tenderness in extremities since 8 months prior to her present admission. x-ray of extremities revealed callus formation, osteopenia and site of healed fractures. bone marrow aspiration revealed all-l2 with normal peripheral sm...

Further improvement of outcome in childhood acute lymphoblastic leukemia could be achieved by identifying additional high-risk patients who may benefit from intensified treatment. We earlier identified PTPRC (CD45) gene expression as a potential new stratification marker and now analyzed the prognostic relevance of CD45 protein expression. CD45 was measured by flow cytometry in 1065 patients tr...
