The NOTCH signaling pathway is a conserved signaling cascade that regulates many aspects of development and homeostasis in multiple organ systems. Aberrant activity of this signaling pathway is linked to the initiation and progression of several hematological malignancies, exemplified by T-cell acute lymphoblastic leukemia (T-ALL). Interestingly, frequent non-mutational activation of NOTCH1 signaling has recently been demonstrated in B-cell chronic lymphocytic leukemia (B-CLL), significantly extending the pathogenic significance of this pathway in B-CLL...

Acute lymphoblastic leukemia is commonly cured when diagnosed in the pediatric population. It portends a poorer prognosis if present in adult patients. Although adults frequently achieve complete remission, relapse rates are substantial, particularly among the elderly and high-risk populations. In the absence of prophylactic intrathecal chemotherapy, more than half of patients may develop CNS involvement or relapse, which is associated with significant risk for systemic illness. This report describes a patient with acute lymphoblastic leukemia with repeated isolated CNS relapses...

BACKGROUND: Acute lymphoblastic leukemia (ALL) in adults is an invariably aggressive and rare disease. Its treatment is based on the use of multidrug regimens, which have been improved since the 1970s. Few published data are available on the results of adult ALL treatment in Latin America. MATERIALS AND METHODS: We retrospectively analyzed the data from 59 patients with ALL treated from 2009 to 2015 at Hospital of Clinics of University of São Paulo, using an adapted German Multicenter ALL (GMALL) protocol (07/2003)...

BACKGROUND: For patients who have acute promyelocytic leukemia (APL) in second complete remission (CR2), optimal postremission strategies remain undefined. METHODS: The role of an oral arsenic trioxide (As2 O3 )-based regimen in the management of patients who had APL in CR2 was examined. RESULTS: Seventy-three patients with APL in first relapse (R1) were studied. Oral As2 O3 -based reinduction resulted uniformly in CR2, irrespective of previous As2 O3 exposure...

Central nervous system (CNS) hematologic malignancies, whether primary or secondary, are uncommon and their clinical presentations vary. Intravascular lymphoma (IVL) is a very rare, aggressive systemic malignancy that is often difficult to diagnose and susceptible to early CNS involvement. Blast crisis in myeloid leukemias can cause widespread neoplastic emboli. Here, we report two adult patients (72 years and 22 years of age) who presented with altered mental status followed by rapid decline in their conditions leading to death...

Aggressive central nervous system (CNS)-directed treatment for acute lymphoblastic leukemia (ALL), the most prevalent cancer among children and adolescents, prevents metastasis of leukemia cells into the brain. Up to 60% of survivors experience cognitive problems, but knowledge about risk factors for and mechanisms of neurologic injury is lacking. Objectives of the present study were to (1) quantify changes in oxidant defense and apoptosis over the course of ALL therapy and (2) elucidate risk factors for long-term cognitive problems...

Decreased height of the eyelid or the narrowing of the lid is called ptosis. Ptosis has several causes. Malignancy-related conditions such as Horner's syndrome, which causes unilateral ptosis in the pediatric age group, and patients with malignancy receiving chemotherapeutic treatment, are often secondary to these drugs and ptosis is a clue of underlying diseases. Underlying pathologies can lead to different clinical conditions such as cognitive impairment from coma, the presence of ptosis should be cautionary...

BACKGROUND: Cytological analysis of the cerebrospinal fluid (CSF) remains the most widely used method for diagnosing central nervous system (CNS) involvement in acute lymphoblastic leukemia (ALL). This study aimed at evaluating the use of polymerase chain reaction (PCR), in comparison to other methods, for the assessment of the presence of blast cells in the CSF at the time of diagnosis of ALL. METHODS: This was a prospective, single-centre, study enrolling all patients up to the age of 18 years who were admitted to a university hospital between November 2011 and November 2014 with a diagnosis of ALL and from whom it was possible to draw a sufficient amount of CSF for analysis by conventional cytology (CT), immunophenotyping (IMP), and PCR...

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 and are at 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. In this study, we examined inflammatory factors (IL-6 and TNF-α) and adipokines (adiponectin, leptin), in addition to body composition and adiposity, in cancer survivors who underwent hematopoietic cell transplantation (HCT) during childhood compared with sibling controls...

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"...
