Acute leukemia, the most common form of cancer in children, accounts for approximately 30% of all childhood malignancies, with acute lymphoblastic leukemia being five times more frequent than acute myeloid leukemia. Lineage switch is the term that has been used to describe the phenomenon of acute leukemias that meet the standard French-American-British system criteria for a particular lineage (...
BACKGROUND Recently, in genome-wide analyses of DNA copy number abnormalities using single nucleotide polymorphism microarrays, genetic alterations targeting PAX5 were identified in over 30% of pediatric patients with acute lymphoblastic leukemia. So far the occurrence of PAX5 alterations and their clinical correlation have not been investigated in adults with BCR-ABL1-positive acute lymphoblas...
OBJECTIVE Cognitive impairments had been reported in childhood acute lymphoblastic leukemia, what caused the impairments needed to be demonstrated, chemotherapy-related or the disease itself. The primary aim of this exploratory investigation was to determine if there were changes in brain function of children with acute lymphoblastic leukemia before chemotherapy. METHODS In this study, we adv...
BACKGROUND Allogeneic hematopoietic cell transplantation is a potentially curative treatment for patients with acute lymphoblastic leukemia. However, the majority of older adults with acute lymphoblastic leukemia are not candidates for myeloablative conditioning regimens. A non-myeloablative preparative regimen is a reasonable treatment option for this group. We sought to determine the outcome ...
Translocation of the LYL1 oncogene are rare in T-cell acute lymphoblastic leukemia, whereas the homologous TAL1 gene is rearranged in approximately 20% of patients. Previous gene-expression studies have identified an immature T-cell acute lymphoblastic leukemia subgroup with high LYL1 expression in the absence of chromosomal aberrations. Molecular characterization of a t(7;19)(q34;p13) in a ped...
Abstract Introduction/Objective Myeloid/lymphoid neoplasms with rearrangement of FGFR1 are uncommon and heterogeneous group hematological malignancies that may present as myeloproliferative neoplasm, acute myeloid leukemia, T or B lymphoblastic lymphoma/leukemia, mixed phenotypic leukemia. Patients can lymphadenopathy, mediastinal mass, systemic symptoms. Eosinophilia is common in peripheral bl...
Compared with the general pediatric population, children with Down’s syndrome have a much higher risk of acute leukemia. This case-control study was designed to explore potential risk factors for acute lymphoblastic leukemia and acute myeloid leukemia in children with Down’s syndrome living in the United States or Canada. Mothers of 158 children with Down’s syndrome and acute leukemia (97 acute...
Anterior Chest Wall Bulging: A Rare Initial Manifestation of Acute Lymphoblastic Leukemia in a Child
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 ...
Compared with the general pediatric population, children with Down's syndrome have a much higher risk of acute leukemia. This case-control study was designed to explore potential risk factors for acute lymphoblastic leukemia and acute myeloid leukemia in children with Down's syndrome living in the United States or Canada. Mothers of 158 children with Down's syndrome and acute leukemia (97 acute...
عفونتهای پاروویروسی با طیفی وسیعی از بیماری ها همراه می باشند. چندین عضو از خانواده پاروویریده در افراد مبتلا مورد شناسایی قرار گرفته اند. در این مقاله ما درباره پاتوژنز این عفونت ها و طیفی از بیماری های بالینی مرتبط با آن ها، بحث خواهیم کرد. نقش این ویروس ها در تنظیم پیش سازهای اریتروئیدی و همچنین نقش احتمالی آن ها در بروز بیماری خود ایمنی و لوسمی لنفوبلاستیک حاد مورد تاکید قرار گرفته است.
