Busulfan (Bu)-based preparative regimens in hematopoietic stem cell transplantation are commonly used. Previous studies have shown that Bu at a fixed dose of 3.2mg/kg/day (FBD) given intravenously decreases variability in drug pharmacokinetics and this decreases the dependency on therapeutic drug monitoring (TDM) of Bu. We compared the Bu dose given using TDM with the FBD of 3.2mg/kg/day. Seventy-three patients with acute leukemia, myelodysplasia, chronic myeloid leukemia, thalassemia major, and sickle cell disease were included...

Nontransfusion-dependent β-thalassemia (NTDβT) syndromes consist of β-thalassemia intermedia and moderate hemoglobin E/β thalassemias. They are characterized by varying degrees of chronic anemia and a wide spectrum of complications due to ineffective erythropoiesis and iron overload from chronic transfusions. Hydroxyurea (HU), an oral chemotherapeutic drug, is anticipated to decrease disease severity. We performed a meta-analysis to evaluate the clinical efficacy and safety of HU in NTDβT patients of any age...

Mantle cell lymphoma is a clinically heterogeneous disease occurring within a heterogeneous patient population, highlighting a need for personalized therapy to ensure optimal outcomes. It is therefore critical to understand the benefits and risks associated with both intensive and deintensified approaches. In the following review we provide a therapeutic roadmap to strategically guide treatment for newly diagnosed and relapsed/refractory patients highlighting pivotal and recently published results involving known and novel therapies...

OBJECTIVE/BACKGROUND: Noninfection-related fever can occur after peripheral blood stem cell infusion in haploidentical hematopoietic stem cell transplantation with post-transplant cyclophosphamide. The objective of this study was to analyze the incidence of fever and characterize some clinical features of affected patients. METHODS: A retrospective case-series study with 40 patients who received haploidentical hematopoietic stem cell transplantation was carried out...

OBJECTIVES/BACKGROUND: CXCR4 is a receptor for stromal-derived factor-1 (SDF-1), a molecule that has a chemotactic activity for lymphocytes and is important in homing of hematopoietic stem cells to their adult marrow. We evaluated the CXCR4 (CD184) expression in the harvest cells and in the post-transplant bone marrow (BM) and its relation to engraftment, as determined by the consensus criteria and chimerism. METHODS: This is a prospective study which included 30 patients undergoing hematopoietic stem cell transplantation; 15 patients received autograft and 15 patients received allograft on dates between January 2012 and May 2014...

Thrombocytopenia with absent radii (TAR) syndrome is a rare congenital disorder characterized by low platelet counts of various severity, bilateral absent radii but thumbs are usually present. TAR syndrome is not generally associated with bone marrow failure or malignancy. Janus kinase-2, myeloproliferative leukemia protein, and calreticulin are not mutated in TAR patients. Only four cases of leukemia were reported in TAR patients in the literature: three acute myeloid leukemia (AML) and one acute lymphoblastic leukemia...

OBJECTIVE/BACKGROUND: From clinical and biological points of view, chronic lymphocytic leukemia (CLL) is a heterogeneous disease characterized by a progressive accumulation of lymphocytes in the peripheral blood, bone marrow, and lymphoid organs. New prognostic markers in CLL may be useful to clinicians for predicting outcome and in clinical decision-making. The aim of this study was to evaluate the potential prognostic value of the apoptotic/survival-controlling proteins and protein tyrosine kinase ZAP-70 gene expression in CLL patients and control individuals, correlating such findings with patients' clinical data...

Synovial sarcoma is a high-grade soft tissue sarcoma that rarely arises in the head and neck region. It affects the parapharyngeal space and the hypopharynx most commonly and it has different presentations based on the affected site. In extremely rare occasions, it involves the hard palate such as in our case where a 24-year-old female patient presented with a mass lesion involving the left hard palate, which was identified clinically and by imaging studies. The histopathological assessment confirmed that it was a monophasic synovial sarcoma which was also confirmed with further molecular studies...

Relapse of Hodgkin lymphoma after autologous hematopoietic cell transplantation (autologous HCT) is a major therapeutic challenge. Its management, at least in younger patients, traditionally involves salvage chemotherapy aiming to achieve disease remission followed by consolidation with allogeneic hematopoietic cell transplantation (allogeneic HCT) in eligible patients. The efficacy of salvage therapy is variable and newer combination chemotherapy regimens have improved the outcomes. Factors such as shorter time to relapse after autologous HCT and poor performance status have been identified as predictors of poor outcome...

Acute promyelocytic leukemia (APML) with variant RARa translocations comprises 1-2% of APML cases. However, the diagnosis of these cases is challenging as the routine practice includes fluorescence in situ hybridization (FISH) reverse transcription polymerase chain reaction targeting the PML and RARA genes to detect PML/RARA fusions. Here, we report a case highlighting the importance of atypical FISH signal patterns in standard dual-color dual-fusion PML/RARa FISH analysis complimented by karyotyping to detect these variant RARA translocations...

Hypereosinophilic syndrome (HES) is a group of rare blood disorders characterized by a persistent elevation of blood eosinophil count ⩾1.5×10(9)/L and clinical manifestations attributable to eosinophilia or tissue hypereosinophilia. Lymphocytic variant of HES (HES-L) is a known subtype according to World Health Organization classification. It is well documented in the literature that patients with HES-L are predisposed to develop T-cell lymphoma. We report a case of T-cell lymphoproliferation associated with hypereosinophilia, which has been successfully treated with mycophenolate mofetil, with resolution of skin lesions and normalization of eosinophil count and immunoglobulin E level...

OBJECTIVE/BACKGROUND: To assess the percentage of CD4(+), CD8(+), and natural killer cells (CD16(+), CD56(+)) in children with immune thrombocytopenic purpura (ITP) at presentation and study their impact on disease chronicity. METHODS: This case-control study was conducted at the Pediatric Hematology and Oncology Unit, Menoufia University Hospital (tertiary care center in Egypt). The study was held on 30 children presenting with ITP; they were followed-up and classified into two groups: 15 children with acute ITP; and 15 children with chronic ITP...

OBJECTIVE/BACKGROUND: A decision about the need for antimicrobial therapy in a patient with febrile neutropenia after hematopoietic stem cell transplantation (HSCT) is often complicated because of the low frequency of culture isolation and reduced clinical manifestation of infection. Usefulness and choice of sepsis biomarkers to distinguish bloodstream infection (BSI) from other causes of febrile episode is still argued in HSCT recipients in modern epidemiological situations characterized by the emergence of highly resistant gram-negative microorganisms...

OBJECTIVE/BACKGROUND: Here, we described the clinical characteristics and outcomes of central nervous system (CNS) infections occurring after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in a single institution over the previous 6 years. METHODS: Charts of 353 consecutive allogeneic transplant recipients were retrospectively reviewed for CNS infection. RESULTS: A total of 17 cases of CNS infection were identified at a median of 38 days (range, 10-1028 days) after allo-HSCT...

OBJECTIVE/BACKGROUND: Acute myeloid leukemia (AML) is defined as leukemic blast reproduction in bone marrow. Chromosomal abnormalities form different subgroups with joint clinical specifications and results. t(8;21)(q22;q22) and inv(16)(p13;q22) form core binding factor-AML (CBF-AML). c-kit mutation activation occurs in 12.8-46.1% of adults with CBF leukemia. These mutations occur in 20-25% of t(8;21) and 30% of inv(16) cases. METHODS: In this systematic review, we searched different databases, including PubMed, Scopus, and Embase...
