Resumen
Acute lymphoblastic leukemia is typically characterized by leukocytosis, resulting from the uncontrolled proliferation of malignant cells. However, we report an atypical case of acute lymphoblastic leukemia that presented with leukopenia and exhibited a protracted clinical course spanning 6 months. The patient, a 45-year-old female, initially presented to our hospital with recurrent fever and was found to have lymphoblasts in a hypoplastic bone marrow. Upon further investigation, the patient was diagnosed with B-cell lymphoblastic leukemia, not otherwise specified, based on cell surface antige

Resumen
The AML1 ( acute myeloid leukemia 1) gene, a necessary prerequisite of embryonic hematopoiesis and a critical regulator of normal hematopoietic development, is one of the most frequently mutated genes in human leukemia, involving over 50 chromosome translocations and over 20 partner genes. In the few existing studies investigating AML1 gene expression in childhood leukemias, aberrant upregulation seems to specifically associate with AML1 translocations and amplifications. The aim of this study was to determine whether overexpression also extends to other leukemic subtypes than the ones karyoty

ABSTRACT Background: Leukemic cells express a characteristic set of “cluster of differentiation” (CD) markers, which forms the basis of the current WHO classification. Leukemia-associated aberrant immunophenotype (LAIP) refers to expression of unusual CD markers by leukemic cells, which are not normally expressed by their respective lineage. The incidence of LAIP varies considerably, and its clinical implications, prognostic relevance, and sensitivity to therapy are still debatable.

Abstract MicroRNAs (miRNAs), an abundant class of ~22-nt endogenous regulatory RNAs that control gene expression at the posttranscriptional levels, have been implicated to play roles in the normal hematopoiesis and pathogenesis of leukemias. To identify “leukemic miRNAs”--miRNAs that may be oncogenes or tumor suppressors in human leukemias, we systematically cloned miRNAs from the blast cells of childhood acute lymphoblastic leukemia (ALL) patients with either a poor prognostic mixed-lineage leukemia rearrangement phenotype (MLL) or a prognostically more favorable precursor B-cell ALL phenotyp

The etiology is unknown but radiation and some chemical exposure, as well as genetics, might play a role. The disease onset is abrupt. Clinical presentation is characterized by a variety of general symptoms: fatigue, malaise, night sweats, weight loss, fever.

Resumen
Acute Lymphoblastic leukemias (ALL) are a heterogeneous group of neoplasms which can either be having precursor B cell immunophenotype or mature B cell immunophenotype. Surface immunoglobulin light chain restriction is usually a feature of mature B cell neoplasms. A precursor B cell lymphoblastic leukemia (pre-B-ALL) with surface immunoglobulin light chain expression is a rare immunophenotype . We report a case of a 4 year old female with L1 type of blast morphology yet showing surface light chain restriction. Recognizing this rare immunophenotype and arriving at a correct diagnosis has therap

Resumen
One key process that controls leukemogenesis is the regulation of oncogenic gene expression by transcription factors acting as tumor suppressors. Understanding this intricate mechanism is crucial to elucidating leukemia pathophysiology and discovering new targeted treatments. In this review, we make a brief overview of the physiological role of IKAROS and the molecular pathway that contributes to acute leukemia pathogenesis through IKZF1 gene lesions. IKAROS is a zinc finger transcription factor of the Krüppel family that acts as the main character during hematopoiesis and leukemogenesis. It c

Resumen
Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. Survival probability of pediatric ALL had been 10-20%, but the most recent clinical trials with multiagent chemotherapy have achieved overall survival probability of better than 80%. This is achieved because of better supportive care, treatment stratification based on relapse risk, and the biological features of leukemic cells. Diagnosis of ALL was based principally on morphological identification of leukemic blasts in bone marrow, and immunophenotype assessment by flow cytometry is necessary, and most pediatric ALL cases

Abstract Abstract 1521 Refractory and relapse acute lymphoblastic leukemia (ALL) is one of the leading causes of cancer-related death in children. Novel agents are still in need as a frontline therapy in high risk patients and salvage agent in relapse patients. Leukemic cells acquire a survival advantage over normal blood cells by losing control of the cell cycle and activating pro-survival signals. There are emerging evidences showing that the PI3K/AKT/mTOR pathway is frequently activated in both T cell acute lymphoblastic leukemia (T-ALL) and precursor B cell acute lymphoblastic leukemia (pr

Resumen
Myelodysplastic syndromes (MDS) comprise a group of heterogeneous clonal hematopoietic cell disorders characterized by cytopenias, bone marrow hypercellularity, and increased risk of transformation to acute leukemias. MDS usually transformed to acute myeloid leukemia, and transformation to acute lymphoblastic leukemia (ALL) is rare. Herein, we report a unique patient who presented with MDS with myelofibrosis. Two months after the initial diagnosis, she progressed to a precursor B-cell acute lymphoblastic leukemia. She was treated with induction therapy followed by allogenic stem cell transplan

Resumen
Acute lymphoblastic leukemia is predominantly found in children. It is a neoplasm of precursor cells or lymphoblasts committed to either a B- or T-cell lineage. The immature cells in B-acute lymphoblastic leukemia/lymphoma can be small or medium sized with scant or moderate cytoplasm and typically express B-cell markers such as CD19, cytoplasmic CD79a, and TdT without surface light chains. These markers, along with cytogenetic studies, are vital to the diagnosis, classification, and treatment of these neoplasms. We present an unusual case of a precursor B-cell ALL, in an 82-year-old woman, who

Leukemia is the most common pediatric cancer, diagnosed in over 3,000 children annually in the US. While the prognosis for many pediatric leukemias has significantly improved with the addition of DNA sequencing to the diagnosis and treatment selection process, the molecular mechanisms driving some cases remain inscrutable. In this study, we performed single-cell RNA sequencing on a cohort of pediatric leukemia samples (n = 72) to explore intra- and inter-patient heterogeneity across multiple types of malignancies: acute megakaryoblastic leukemia (AMKL, n = 1), acute myeloid leukemia (AML, n =

Resumen
Abstract Abstract 3158 MicroRNA miR-125b has been shown to be involved in different kind of leukemia. Indeed, the chromosomal translocation t(2;11)(p21;q23) found in patients with myelodysplasia and acute myeloid leukemia leads to an overexpression of miR-125b up to 90 fold. Moreover, miR-125b is also upregulated in patients with B-cell acute lymphoblastic leukemia carrying the t(11;14)(q24;q32) translocation. To decipher the presumed oncogenic mechanism of miR-125b, we used transplantation experiments in mice. All of the mice transplanted with fetal liver cells ectopically expressing miR-125b

Resumen
Classical and up-to-date models of hematopoietic lineage determination are briefly reviewed with the focus on myeloid-based models challenging the existence of the common progenitor for T cells, B cells and NK cells. The analysis of immunophenotype of leukemic blast cells seems to be a promising approach for interpreting some controversies in the schemes of normal hematopoiesis. The liter ature data as well as our own findings in the patients with various types of acute leukemias are in favor of the concept postulating that common myeloid-lymphoid progenitors giving rise to T and B cell branch
