Nijmegen breakage syndrome (NBS) is a rare autosomal recessive chromosomal instability disorder characterized by microcephaly, immunodeficiency, radiosensitivity and a very high predisposition to malignancy. The gene responsible for the disease, NBS1, is located on chromosome 8q21 and encodes a protein called nibrin. After identification of the gene, a truncating 5 bp deletion, 657-661delACAAA, was identified as the disease-causing mutation in patients with the NBS. In this report, we describe two patients with NBS and T-lymphoblastic leukemia/lymphoma in a Macedonian family...

BACKGROUND: Optimizing patient selection is a necessary step to design better clinical trials. 'Life expectancy' is a frequent inclusion criterion in phase II trial protocols, a measure that is subjective and often difficult to estimate. The aim of this study was to identify factors associated with early death in patients included in phase II studies. METHODS: We retrospectively collected medical records of patients with advanced solid tumors included in phase II trials in two French Comprehensive Cancer Centers (Bordeaux, Center 1 set; Lille, Center 2 set)...

Acute myeloid leukemia (AML) involvement of the central nervous system is relatively rare, and detection of leptomeningeal disease typically occurs only after a patient presents with neurological symptoms. The case herein describes a 48-year-old man with relapsed/refractory AML of the mixed lineage leukemia rearrangement subtype, who presents with monocular vision loss due to leukemic eye infiltration. MRI revealed right optic nerve sheath enhancement and restricted diffusion concerning for nerve ischemia and infarct from hypercellularity...

The authors present a case of a 60-year-old male patient, previously diagnosed with B-cell chronic lymphocytic leukemia, who was admitted to the Emergency Room with dyspnea. The initial evaluation revealed severe anemia (Hgb = 5.0 g/dL) with hyperleukocytosis (800.000/µL), nearly all of the cells being mature lymphocytes, a normal chest X-ray and a low arterial oxygen saturation (89%; pulse oximetry). After red blood cell transfusion, Hgb values rose (9.0 g/dL) and there was a complete reversion of the dyspnea...

Infants with Down syndrome (DS) are at risk of developing a transient myeloproliferative disorder during the neonatal period, known as transient abnormal myelopoiesis (TAM). It is characterized by clonal myeloproliferation and is typically self-limiting. However, TAM can be a life-threatening disorder, when complicated by liver fibrosis. Here, we evaluated cytokine profiles in two male DS infants having TAM with or without liver dysfunction. The first patient, Patient 1, had hyperleukocytosis with cholestatic liver dysfunction, coagulopathy, and increased counts of blasts and was treated with exchange transfusion (ExT) due to the serious general condition...

The recent years have witnessed tremendous progress in the molecular characterization of Philadelphia-negative myeloproliferative neoplasms (MPN). Beside a better understanding of pathophysiology, these abnormalities often constitute very useful diagnostic markers in diseases where exclusion of reactive states used to be the strongest argument. However, conventional and molecular cytogenetics keep a major interest in MPN, either as a second line exploration, in cases where no molecular marker is available, for differential diagnosis or as a proof of clonality or in first line for cases with hyperleukocytosis, for differential diagnosis (CML), to evidence druggable targets (ABL1, RET, PDGFR…) or as a prognosis marker...

Hyperleukocytosis is present in 5 to 20 percent of patients with newly diagnosed acute myeloid leukemia (AML). The management of hyperleukocytosis, when symptoms of leukostasis occur, includes intensive supportive care and interventions for rapid cytoreduction. Leukapheresis is a rapid and effective means of cytoreduction and has been used in AML patients. In the current study, we evaluated the outcomes of 68 newly diagnosed AML patients that underwent leukapheresis and the effects of leukapheresis on various laboratory parameters...

Early intracranial hemorrhage (eICH) is a potentially fatal complication of acute leukemia. We analyzed risk factors for eICH in patients with de novo acute leukemia. Ninety-one de novo acute leukemia patients at our institution between September 2003 and June 2014 were included. Of the 91 patients, eight (8.8 %) and 83 were included in the eICH and non-eICH groups, respectively. Univariate analysis demonstrated that white blood cell (WBC) count (P = 0.018), fibrin-fibrinogen degradation product (FDP) level (P = 0...

BACKGROUND: Hyperleukocytosis in children with acute lymphoblastic leukemia (ALL) has been associated with early morbidity and mortality. The use of leukapheresis in these children treated with contemporary therapy remains controversial. PROCEDURE: We analyzed clinical data from patients enrolled onto frontline protocols for ALL (Total Therapy XV and XVI) between 2003 and 2014. We documented adverse events within the first 14 days in patients with a white blood cell (WBC) count ≥200 × 10(9) /l and reviewed their management...

Mature B-cell acute lymphoblastic leukemia (B-ALL) is typically associated with French-American-British (FAB)-L3 morphology and MYC gene rearrangement. However, rare cases of mature B-ALL with non-L3 morphology and MLL-AF9 fusion have been reported, and such cases are characterized by a rapid and aggressive clinical course. We here report three such cases of pediatric mature B-ALL in female patients respectively aged 15 months, 4 years, and 4 months. Bone marrow smears at diagnosis showed FAB-L1 morphology in all patients...

Canonical mutations in IDH1 and IDH2 produce high levels of the R-enantiomer of 2-hydroxyglutarate (R-2HG), which is a competitive inhibitor of α-ketoglutarate (αKG)-dependent enzymes and a putative oncometabolite. Mutant IDH1 collaborates with HoxA9 to induce monocytic leukemia in vivo. We used two mouse models and a patient-derived acute myeloid leukemia xenotransplantation (PDX) model to evaluate the in vivo transforming potential of R-2HG, S-2HG and αKG independent of the mutant IDH1 protein. We show that R-2HG, but not S-2HG or αKG, is an oncometabolite in vivo that does not require the mutant IDH1 protein to induce hyperleukocytosis and to accelerate the onset of murine and human leukemia...

Leukostasis is a poorly understood and life-threatening complication of acute hyperleukocytic leukemia. The incidence of hyperleukocytosis and leukostasis differs among various subtypes of leukemias. While the pathophysiology of leukostasis is not fully understood, recent research has elucidated many novel pathways that may have therapeutic implications in the future. Respiratory and neurological compromise represents the classical clinical manifestations of leukostasis. If it is not diagnosed and treated rapidly, the one-week mortality rate is approximately 40%...

Adequate management of hyperleukocytosis in patients with acute myeloid leukemia (AML) is essential for the prevention of life-threatening complications related to leukostasis and tumor lysis syndrome, but the optimal therapeutic strategy remains unclear. We report a 15-year-old girl with newly diagnosed AML who had extreme hyperleukocytosis (leukocyte count at diagnosis, 733,000/μl) leading to a brain hemorrhage. She was initially treated with hydroxyurea, but presented with brain hemorrhage due to leukostasis and underwent leukapheresis emergently with intensive care and mechanical ventilation...

Acute myeloid leukemia with high white blood cell count (WBC) is a medical emergency. A reduction of tumor burden with hydroxyurea may prevent life-threatening complications induced by straight chemotherapy. To evaluate this strategy, we reviewed medical charts of adult patients admitted to our institution from 1997 to 2011 with non-promyelocytic AML and WBC over 50 G/L. One hundred and sixty patients were included with a median WBC of 120 G/L (range 50-450), 107 patients received hydroxyurea prior to chemotherapy, and 53 received emergency induction chemotherapy (CT)...
