Acute lymphoblastic leukemia (ALL) has been suggested as a long-term complication in patients with β-thalassemia major (β-TM). A 12-months-old male patient was diagnosed with β-TM. The patient required a blood transfusion weekly for 2 years. At the age of 4 years, a splenectomy was performed due to massive splenomegaly and frequent transfusion requirements. The histopathological analysis of the spleen revealed extensive hemosiderosis. ALL-L1 with the T immunophenotype and without central nervous system (CNS) involvement was diagnosed when the patient was 5 years old, and treated with anti-leukemic combination chemotherapy and CNS radiotherapy...

Cytosine arabinoside (Ara-C) is one of the key drugs for treating acute myeloid leukemia (AML). High intravenous doses may produce a number of central nervous system (CNS) toxicities and contribute to modifications in brain functional connectivity. sLORETA is a software used for localizing brain electrical activity and functional connectivity. The aim of this study was to apply sLORETA in the evaluation of possible effects of Ara-C on brain connectivity in patients with AML without CNS involvement. We studied eight patients with AML; four were administered standard doses of Ara-C while the other four received high doses...

Patients with standard-risk adult acute lymphoblastic leukemia (ALL) treated with chemotherapy do not have satisfactory outcomes. To more precisely classify ALL patients and optimize treatment, we re-evaluated the risk stratification system by examining CD20 expression and other classic risk factors at diagnosis. We retrospectively analyzed response to induction chemotherapy of 217 consecutive patients with newly diagnosed Philadelphia-negative B cell precursor-ALL. Survival analyses were conducted for the 136 patients who were intended to be treated with chemotherapy alone...

BACKGROUND: Acute promyelocytic leukemia (APL) is a rare form of acute myelogenous leukemia (AML). Survival rates exceed 80% in developed countries. Successful treatments rely on all-trans retinoic acid with anthracycline-based chemotherapy. Availability of modern care and public knowledge play important roles in pediatric APL survival. METHOD: A cytogenetic diagnosis of APL was confirmed in 30 (14.5%) out of 207 children consecutively diagnosed with de novo AML between January 2005 and December 2012 at nine cancer care centers in Saudi Arabia...

Adult survivors of acute leukemia in childhood have a higher than expected frequency of obesity, an increased risk for metabolic syndrome and early mortality from cardiovascular disease (CVD). Adipose tissue has been recognized as an endocrine and paracrine organ that secretes various adipokines involved in metabolic regulation and inflammatory processes. Examine inflammatory factors [IL-6 and TNF-] and adipokines (adiponectin, leptin) in addition to body composition and adiposity in cancer survivors who underwent hematopoietic cell transplantation (HCT) during childhood in comparison to sibling controls...

Central nervous system (CNS) involvement at diagnosis of pediatric acute myeloid leukemia (AML) is not considered as an independent prognostic factor. This study describes the prognostic value of pediatric AML with CNS involvement at diagnosis. Pediatric patients were treated for de novo AML in the French multicenter trial ELAM02. Lumbar puncture was carried out in the first week, and the treatment was adapted to the CNS status. No patient received CNS radiotherapy. The patients were classified into 2 groups: CNS+ and CNS-...

Background: B-cell lymphomas harboring the 8q24/MYC plus 18q21/BCL2 translocations are now referred to as high grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (HGBL-MBR). Although HGBL-MBR is frequently found in cases with diffuse large B-cell lymphoma or Burkitt lymphoma-like B-cell lymphoma, acute lymphoblastic leukemia (ALL)-like disease of HGBL-MBR (AL-HGBL-MBR) has been reported incidentally. Case presentation: A 69-year-old Japanese woman developed remittent fever and increasing systemic bone pain...

Treatment of acute lymphoblastic leukemia requires high-dose systemic and/or intrathecal methotrexate to prevent and/or treat central nervous system disorders. Acute neurotoxicity of methotrexate, of unknown etiopathogenesis, is characterized by the polymorphism of clinical manifestations, responsible for a potentially harmful diagnostic delay in these immunosuppressed patients. We describe five episodes of transient acute leukoencephalopathy mimicking a stroke, reported in the literature as "pseudo-stroke syndrome"...

BACKGROUND: Leukemic infiltration of the optic nerve is relatively rare. While previously described in acute leukemia, the infiltration in our case represents central nervous system (CNS) metastasis of Burkitt-type lymphoma that developed as a complication of solid-organ transplantation, resulting in a bilateral infiltrative optic neuropathy with sequential, bilateral central retinal artery occlusion (CRAO) and devastating vision loss. METHODS: The medical record, serial ophthalmic examination findings, clinical course, and imaging including magnetic resonance imaging (MRI), fundus photographs, and fluorescein angiography of a single patient were retrospectively reviewed...

Bacillus cereus is a widely-distributed, gram-positive or variable, rod-shaped bacterium frequently considered a contaminant in clinical specimens. It is recognized as a potential pathogen inducing self-limiting emetic or diarrheal food poisoning or localized infection in immunocompetent patients. True B. cereus bacteremia is uncommon and mainly observed in fragile patients, notably in immunocompromised individuals. We report clinical, radiological, and pathological findings of a 64-year-old patient with a history of acute myeloid leukemia who initially presented a fever while neutropenic after the induction of a second cycle of chemotherapy...

Mixed-lineage leukemia (MLL)-rearranged (MLLr) infant B-cell acute lymphoblastic leukemia (iMLLr-B-ALL) has a dismal prognosis and is associated with a pro-B/mixed phenotype, therapy refractoriness and frequent central nervous system (CNS) disease/relapse. Neuron-glial antigen 2 (NG2) is specifically expressed in MLLr leukemias and is used in leukemia immunophenotyping because of its predictive value for MLLr acute leukemias. NG2 is involved in melanoma metastasis and brain development; however, its role in MLL-mediated leukemogenesis remains elusive...

Myeloid sarcoma (MS) is a localized tumor composed of premature precursors of granulocytic cells, which may occur in any organ and most commonly involves the soft tissue and musculoskeletal system. This malignancy may occur in the presence or absence of hematological disorders. Primary MS involving the central nervous system (CNS-MS) is rare, and has only been described in a small number of isolated case reports. The diagnosis of CNS-MS is challenging and strategies for its management are undefined. The present study describes 4 cases of CNS-MS...

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disease caused by the malignant transformation of immature progenitors primed towards T-cell development. Clinically, T-ALL patients present with diffuse infiltration of the bone marrow by immature T-cell blasts high blood cell counts, mediastinal involvement, and diffusion to the central nervous system. In the past decade, the genomic landscape of T-ALL has been the target of intense research. The identification of specific genomic alterations has contributed to identify strong oncogenic drivers and signaling pathways regulating leukemia growth...

Hematopoietic stem cell transplantation (HSCT) with a non-total body irradiation (TBI) conditioning regimen has proven feasible for treating patients with acute lymphoblastic leukemia (ALL). However, it is commonly believed that for extramedullary involvement of ALL in sanctuary sites, such as the central nervous system (CNS), TBI should not be abandoned. In this study, the outcomes of pediatric ALL patients with CNS involvement (CNS(+)) and without CNS involvement (CNS(-)) treated with TBI-free allogeneic HSCT were retrospectively compared...
