introduction: the majority of leukemia patients are acute leukemia patients, so that about 70.8% lymphoblastic leukemia were acute lymphoblastic leukemia (all) patients and 66.4 % of myeloid leukemia patients were acute myeloid leukemia (aml) in tehran metropolitan. during the last two decades, intensification of therapy by the use of high-dose cytarabine allogeneic stem cell transplantation in...

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...

Myeloid/lymphoid neoplasms with FGFR1 rearrangement (MLN-FGFR1) comprise a heterogeneous group of that can present as myeloproliferative neoplasm, myelodysplastic/myeloproliferative acute myeloid leukemia, T or B lymphoblastic leukemia/lymphoma, mixed phenotype leukemia. The overall outcome these is poor, and patients often show cytogenetic evolution gain additional chromosomal abnormalities le...

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...

BACKGROUND Mutations in the PHF6 gene were recently described in patients with T-cell acute lymphoblastic leukemia and in those with acute myeloid leukemia. The present study was designed to determine the prevalence of PHF6 gene alterations in T-cell acute lymphoblastic leukemia. DESIGN AND METHODS We analyzed the incidence and prognostic value of PHF6 mutations in 96 Chinese patients with T-...

Temozolomide (TMZ), an alkylating agent, is widely used for treating high-grade gliomas. TMZ has been reported to cause secondary myelodysplastic syndrome and acute myeloid leukemia. However, TMZ-related acute lymphoblastic leukemia is rare. Here we describe a 54-year-old woman with glioblastoma multiforme, who developed precursor-B acute lymphoblastic leukemia with translocation (4;11)(q21;q23...

Hematologic malignancy is a risk factor for severe coronavirus disease 2019 (COVID-19) in adults; however, data specific to children with leukemia are limited. High-quality infectious adverse event from the ongoing Children's Oncology Group (COG) standard-risk B acute lymphoblastic leukemia/lymphoma (ALL/LLy) trial, AALL1731, were analyzed provide disease-specific estimate of SARS-CoV-2 infecti...

Two IgM monoclonal antibodies (MAb) with strong reactivity for granulocytes and to a lesser extent for lurkat cell lines were established by immunizing BALBI c mice with a histiocytic cell line (UY37). These two MAbs (designated as 6C9 and 4C4) reacted with blast cells of T-acute lymphoblastic leukemia (T-ALL) and acute myelogenous leukemia (AML) patients as well as leukemic cells from pat...

C hronic lymphocytic leukemia (CLL) is a frequent CD5 + B-cell neoplasia that involves peripheral blood, bone marrow, lymph nodes and other lym-phoid tissues. The median age of patients at diagnosis of CLL is around 70 years old and the prognosis is extremely variable. In spite of some advances in its therapy, CLL continues to be incurable. Due to this fact, and to the prognos-tic heterogeneity...
