Natural killer (NK)/T cell lymphoid malignancy comprises extranodal NK/T cell lymphoma (ENKTL) and aggressive NK cell leukemia (ANKL), and the outcomes for advanced or relapsed/refractory ENKTL and ANKL remain poor. Allogeneic stem cell transplantation (SCT) can be used as a frontline consolidation treatment to prevent the relapse of advanced disease or as salvage treatment after chemotherapy for relapsed sensitive disease. We retrospectively analyzed 36 patients (ENKTL, n = 26; ANKL, n = 10) who underwent upfront (n = 19) and salvage allogeneic SCT (n = 17) at 6 hospitals...

Background: Acute lymphoblastic leukemia (ALL) is a malignant disease of lymphoid progenitor cells. ALL chemotherapy is associated with numerous side effects including neutropenia that is routinely prevented by the administration of growth factors such as granulocyte colony-stimulating factor (G-CSF). To date, the effects of G-CSF treatment on the level of mobilization of different stem and progenitor cells in ALL patients subjected to clinically effective chemotherapy have not been fully elucidated...

BACKGROUND: Febrile neutropenia (FN) can be a life-threatening complication in children with malignancies. There is no standardized preventive treatment for childhood FN, and information on C-reactive protein (CRP) elevation in afebrile patients with neutropenia (CEAN) is limited. The aim of this study was therefore to identify the association between CEAN and FN onset, and evaluate the efficacy of broad-spectrum antibiotics for FN prophylaxis. METHODS: We retrospectively reviewed the medical records of 22 consecutive pediatric patients with hematologic malignancies (acute myeloid leukemia, n = 2; acute lymphoid leukemia, n = 20) admitted to the present institution between 2006 and 2011...

Invasive fungal disease (IFD) represents an important complication in patients with acute lymphoid leukemia (ALL). The objectives of this study were to determine the prevalence of IFD in ALL patients with neutropenia, identify factors associated with IFD, and estimate the impact of IFD on the outcome. All patients with ALL who developed febrile neutropenia from 1987 to 2013 were evaluated. Cases of IFD were classified as proven or probable. Factors associated with IFD were evaluated by comparing episodes with and without a diagnosis of IFD...

Pseudomonas aeruginosa is a low-virulence pathogen that can cause infection in immunocompromised patients. Among pediatric hematologists, it is known that careful attention should be paid to P. aeruginosa as the bacteria responsible for intraoral inflammation, and antibiotic therapy targeting P. aeruginosa is the first-line treatment during neutropenia in patients with hematological malignancy. Immunosuppressed patients, however, are at high risk of developing inflammation. Here, we report a case involving a 10-year-old patient with acute lymphoid leukemia (ALL), in which P...

Therapeutic options for patients with relapsed or refractory acute leukemia are still undefined and often unsatisfactory. We report the outcome of 79 patients with relapsed-refractory acute leukemia treated with fludarabine, cytarabine, and liposomal daunorubicin (FLAD regimen) followed by hematopoietic stem cell transplantation (HSCT), when clinically indicated, between May 2000 and January 2013. Forty-one patients had acute myeloid leukemia (AML), and 38 had acute lymphoblastic leukemia (ALL). Two patients with myeloid blast crises of CML and three with lymphoid blast crises were included in the AML and ALL subgroups, respectively...

The transcription factor lymphoid enhancer-binding factor 1 (LEF-1), which plays a definitive role in granulocyte colony-stimulating factor (G-CSF) receptor-triggered granulopoiesis, is downregulated in granulocytic progenitors of severe congenital neutropenia (CN) patients. However, the exact mechanism of LEF-1 downregulation is unclear. CN patients are responsive to therapeutically high doses of G-CSF and are at increased risk of developing acute myeloid leukemia. The normal expression of LEF-1 in monocytes and lymphocytes, whose differentiation is unaffected in CN, suggests the presence of a granulopoiesis-specific mechanism downstream of G-CSF receptor signaling that leads to LEF-1 downregulation...

We found that hematopoietic cell-specific Lyn substrate 1 (HCLS1 or HS1) is highly expressed in human myeloid cells and that stimulation with granulocyte colony-stimulating factor (G-CSF) leads to HCLS1 phosphorylation. HCLS1 binds the transcription factor lymphoid-enhancer binding factor 1 (LEF-1), transporting LEF-1 into the nucleus upon G-CSF stimulation and inducing LEF-1 autoregulation. In patients with severe congenital neutropenia, inherited mutations in the gene encoding HCLS1-associated protein X-1 (HAX1) lead to profound defects in G-CSF-triggered phosphorylation of HCLS1 and subsequently to reduced autoregulation and expression of LEF-1...

BACKGROUND: Prolonged chemotherapy-induced neutropenia is a major risk factor for the development of severe bacterial and fungal infections. Infectious manifestations may progress despite adequate anti-infectious treatment and lead to a very high short-term mortality. Granulocyte transfusion (GT) therapy is often considered. However, its efficacy is not well documented. METHODS: We retrospectively analyzed the clinical characteristics and outcome of a cohort of patients with haematological malignancies receiving GT during neutropenia and severe infection...

Dasatinib (BMS-354825, Sprycel®) is an oral, multitargeted inhibitor of receptor tyrosine kinases (RTKs), including BCR-ABL fusion protein, stem cell factor receptor (c-KIT), platelet-derived growth factor receptor (PDGFR), and Src family kinases (SFKs). Several early- and late-phase clinical trials for chronic myelogeneous leukaemia (CML) have demonstrated the direct inhibition of BCR-ABL fusion protein and SFKs, which led to dasatinib approval by the Food and Drug Administration (FDA) and the European Union for the treatment of imatinib-resistant or -intolerant CML, and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL)...

Severe sepsis defined as infection-induced organ dysfunction or hypoperfusion abnormalities predispose to septic shock and increased mortality in neutropenic setting. We aimed at determining predictors of severe sepsis in neutropenic patients. Between 1 October and 31 December 2007, 41 patients (21 with acute myeloid leukemia, 19 with acute lymphoid leukemia and one with autologous stem cell transplantation for a mantle cell lymphoma) with chemotherapy-induced neutropenia (<0.5 x 10(9)/l) lasting for more than 7 days were included in this study...

Traditionally, classification of leukaemia in dogs has relied on morphological examination and cytochemical staining patterns, but aberrant cellular morphology and stain uptake often curtails accurate categorization, and historical data based on this classification may be unreliable. Immunophenotyping is now the gold standard for classification of leukaemias. The purpose of this prospective study was to assess the clinical pathological and epidemiological features of a population of dogs with morphologically and immunologically confirmed leukaemia and to compare them within categories: acute and chronic lymphoid leukaemia (ALL and CLL), and acute and chronic myeloid leukaemia (AML and CML)...

Concordance of MLL-rearranged acute leukemia in infant monozygotic twins is thought to be 100% with a very short latency period, suggesting that either the MLL fusion itself is sufficient to cause leukemia or that it promotes the rapid acquisition of additional oncogenic events that result in overt disease. We report the first case of discordance in an infant monozygotic twin pair. Twin A presented at age 9 months with MLL-ENL(+) acute lymphoblastic leukemia and twin B remains healthy 3 years later. The presence and eventual clearance of a clonal population of MLL-ENL(+) cells was shown in the bone marrow and peripheral blood of twin B...

Severe congenital neutropenia (CN) is a rare bone marrow failure syndrome with a high incidence of acute leukemia. In previous studies, we could show that point mutations in the gene for the granulocyte colony-stimulating factor (G-CSF) receptor CSF3R are a highly predictive marker for leukemic development in CN patients. To find out at which stage of hematopoietic development these mutations emerge and how they are propagated during hematopoietic differentiation, we analyzed single cells of different hematopoietic subpopulations from CN patients with CSF3R mutations...

Acute leukaemia is known as the most common cancer in childhood. Febrile neutropenia is a common serious side effect of the cytostatic treatment of malignancies. The clinical use of Granulocyte Colony Stimulating Factor (G-CSF) has become widespread to minimize chemotherapy-induced myelosuppression and febrile neutropenia in childhood solid tumors, acute lymphoid leukaemia (ALL) and in several trials with AML. In case of ALL this seems to be reasonable because, due to the absence of G-CSF receptor (G-CSFR) on the surface of normal lymphoid cells, G-CSF does not have any influence on the pathways of proliferation and differentiation of lymphoid lineage cells...

The safety of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with acute leukemia has been well established in numerous clinical trials. The primary aim of these studies was to determine whether CSFs, when used as adjuncts to intensive chemotherapy, reduced the duration of neutropenia, prevented febrile neutropenia, infections, and hospitalization rates, and improved response and overall outcome in patients with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL)...
