Haploidentical hematopoietic stem cell transplantation (HSCT) is being increasingly used due to improvement of the transplantation procedures allowing a reduction of graft-versus-host-disease (GVHD) and of transplant-related mortality (TRM). Such improvements have been particularly observed after administration of T-replete HSCT graft associated to an in vivo T cell depletion by the administration of high-doses of cyclophosphamide (HD-Cy) after transplantation. Here, we have analyzed the results of haplo-identical T replete HSC transplants, in particular, when performed with post-transplant HD-Cy in order to provide recommendations for the clinical practice...

Long survival is obtained in 30-40% of adult T-cell leukemia-lymphoma (ATL) patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT) using HLA-matched related or unrelated donors. Myeloablative conditioning is generally used for patients 55 years of age and older, while reduced intensity conditioning is given to those between 50-70 years of age. Overall survival periods do not differ significantly between these two conditioning methods. Survival rates with cord blood transplantation are not inferior to those obtained with bone marrow transplantation or peripheral blood stem cell transplantation...

BACKGROUND: Iron overload is one of the most significant problems as a leading cause of death in patients with leukemia and those who underwent allogeneic hematopoietic stem cell transplantation (alloHSCT). METHODS: In the current study, we retrospectively evaluated the bone marrow iron scores (BMIS) in patients who underwent alloHSCT (n = 125). The first available bone marrow biopsy specimens prior to the alloHSCT procedure or date of hospitalization (control group) were assessed in a blinded fashion using a standardized scoring system...

The bone marrow is one of the largest organs in the body and is visible in every magnetic resonance (MR) imaging study. It is composed of a combination of hematopoietic red marrow and fatty yellow marrow, and its composition changes throughout life in response to normal maturation (red to yellow conversion) and stress (yellow to red reconversion). MR imaging is highly sensitive for detection of altered marrow signal intensity, and the T1-weighted spin-echo sequence provides the most robust contrast between yellow marrow and disease...

Aggressive natural killer cell leukemia (ANKL) is a systemic NK-cell neoplasm, almost always associated with Epstein-Barr virus (EBV). Rare cases of EBV-negative ANKL have been described, and some reports suggested more indolent behavior. We report the clinicopathologic, immunophenotypic, and molecular characteristics of 7 EBV-negative ANKL. All patients were adults, with a median age of 63 years (range 22 to 83 y) and an M:F ratio of 2.5:1. Five patients were White, 1 Black, and 1 Asian. All patients presented acutely, with fever (6/7), cytopenias (6/7), and splenomegaly (4/7)...

8p11 myeloproliferative syndrome (EMS) is a very rare clinicopathological entity which is characterized by the appearance of a myeloproliferative neoplasm in the bone marrow, peripheral lymphadenopathy, usually caused by T or B lymphoblastic lymphoma/leukemia, and a reciprocal translocation involving chromosome 8p11. Herein we describe a 22-year-old male patient with unusual clinical presentation of EMS. Namely, he initially presented with prolonged epistaxis. Complete blood count showed elevated hemoglobin (17...

T-cell large granular lymphocytic (T-LGL) leukemia after hematopoietic stem cell transplantation (SCT) is rare and its natural history and clinical outcome have not been well described. We report the clinical, morphologic, immunophenotypic, and molecular features of a case of donor-derived T-LGL leukemia in a 16-year-old man who received allogeneic SCT for peripheral T-cell lymphoma not otherwise specified (PTCL-NOS). The patient presented with persistent neutropenia and splenomegaly 9 months after SCT when the chimerism study showed a 100% donor pattern...

Emerging evidence suggests that psychosocial factors pre-transplant predict survival in cancer patients undergoing hematopoietic stem cell transplantation (HSCT). These studies, however, typically have small sample sizes, short-term follow ups or a limited panel of medical covariates. We extend this research in a large, well-characterized sample of transplant patients, asking whether patients' perceived emotional support and psychological distress predict mortality over 2 years. Prior to transplant, 400 cancer patients (55...

Skin lesions are frequently encountered in clinical practice which can be a presentation of systemic diseases not excluding an occult malignancy. Commonly reported paraneoplastic dermatologic manifestations include acanthosis nigricans, dermatomyositis, erythroderma, hypertrophic osteoarthropathy, Sweet syndrome, and paraneoplastic pemphigus (PNP). PNP is a rare autoimmune mucocutaneous disease characterized by severe stomatitis, polymorphic skin eruptions, and associated underlying neoplasms most commonly non-Hodgkin's lymphoma, chronic lymphocytic leukemia, and Castleman disease...

Pyogenic granuloma (PG) is a benign, neoplastic, soft tissue growth of granulation and fibrous tissue that may rarely occur in the mouth of patients after hematopoietic cell transplant (HCT). This case series describes 5 pediatric/adolescent patients who developed oral PG after HCT for acute lymphoblastic leukemia, Fanconi anemia, nodular sclerosis Hodgkin's lymphoma, or junctional epidermolysis bullosa. The underlying mechanism for the appearance of oral PG after HCT is unknown, but it is suggested that calcineurin inhibitors used for graft versus host disease (GVHD) may play a role, as all patients were on cyclosporine A or tacrolimus at the time of development of oral PG...

Nuclear warfare at the end of World War II inspired Dick W. van Bekkum to study total-body irradiation (TBI) in animal models. After high-dose TBI, mice died from "primary disease" or bone marrow (BM) aplasia. Intravenous administration of allogeneic BM cells delayed mortality but did not prevent it. Initially the delayed deaths were said to be caused by "secondary disease," which was later renamed graft-versus-host disease (GvHD). GvHD is caused by donor T lymphocytes that destroy recipient cells in skin, intestinal mucosa, bile ducts, and lymph nodes...

Haemorrhagic Cystitis (HC) is defined as diffuse inflammatory bladder bleeding due to many aetiologies. Massive HC often arises from anticancer chemotherapy or radiotherapy for the treatment of pelvic malignancies. Phosphamides are the anti-cancer drugs used for treating breast cancer, B-cell lymphoma, leukemia, rheumatoid arthritis and systemic lupus erythaematosis by cross-linking strands of DNA and preventing the cell division. They are also used in bone marrow transplantation for prevention of Graft Versus Host Disease (GVHD)...

We describe a 4-year-old female with pre-B-cell acute lymphoblastic leukemia on maintenance chemotherapy, who developed hemophagocytic lymphohistiocytosis (HLH) secondary to Epstein-Barr virus (EBV) infection, complicated by an aggressive lymphoproliferative disorder. Although there was no history of bone marrow transplant or underlying immunodeficiency, EBV triggered a post-transplant lymphoproliferative disease (PTLD)-like lymphoma. Multiple regimens of chemotherapy failed to induce remission and patient developed multiorgan failure...

Extramedullary leukemia (EM AML), also known as myeloid sarcoma, is a rare manifestation of acute myelogenous leukemia and often accompanies bone marrow involvement. EM AML is diagnosed based on H&E stains with ancillary studies including flow cytometry and cytogenetics. Isolated EM AML is often misdiagnosed as large cell lymphoma or other lymphoproliferative disorder. The clinical presentation is often dictated by the mass effect and the location of the tumor. The optimal treatment remains unclear. High-dose chemotherapy, radiation, surgical resection, and allogeneic stem cell transplantation are all modalities that can be incorporated into the therapy of EM AML...

The signaling lymphocyte activation molecule family [SLAMF] of cell surface receptors partakes in both the development of several immunocyte lineages and innate and adaptive immune responses in humans and mice. For instance, the homophilic molecule SLAMF6 (CD352) is in part involved in natural killer T cell development, but also modulates T follicular helper cell and germinal B cell interactions. Here we report that upon transplantation of a well-defined aggressive murine B220+CD5+ Chronic Lymphocytic Leukemia (CLL) cell clone, TCL1-192, into SCID mice one injection of a monoclonal antibody directed against SLAMF6 (αSlamf6) abrogates tumor progression in the spleen, bone marrow and blood...

Acute myelogenous leukemia (AML) has an overall poor survival rate and shows considerable molecular heterogeneity in its etiology. In the WHO classification there are >50 cytogenetic subgroups of AML, many showing highly specific chromosome translocations that lead to constitutive activation of individual kinases. In a rare stem cell leukemia/lymphoma syndrome, translocations involving 8p11 lead to constitutive activation of the fibroblast growth factor receptor 1 (FGFR1) kinase. This disorder shows myeloproliferative disease with almost invariable progresses to AML and conventional therapeutic strategies are largely unsuccessful...

Intravascular large B-cell lymphoma (IVLBCL) is a distinct disease entity with the peculiar characteristic that tumor cells proliferate within vessels. Despite recent advances in understanding the disease from clinical aspects, the underlying pathogenesis remains unknown. Here we demonstrate analyses of IVLBCL biology using four xenograft mouse models established from primary IVLBCL samples. In all four models, the main characteristic of IVLBCL tumor cell proliferation within vessels was retained. Time-lapse engraftment analyses revealed that the tumor cells initially engrafted and proliferated in the sinusoids and vessels in the liver and then engrafted and proliferated in multiple organs...

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiologic entity. Its management and outcome in the oncology population is limited because it is still difficult to identify despite an increasingly recognized occurrence. This is the largest retrospective study of PRES in cancer patients reported from a single institution. We explore the clinical manifestations and radiologic features to comprehensively assess PRES in order to prevent permanent neurologic deficits and mortality. We retrospectively identified 69 patients with cancer who developed PRES at MDACC between 01/2006 to 06/2012...

TEN-ELEVEN-TRANSLOCATION-2 (TET2) and DNA-METHYLTRANSFERASE-3A (DNMT3A), both encoding proteins involved in regulating DNA methylation, are mutated in hematological malignancies affecting both myeloid and lymphoid lineages. We previously reported an association of TET2 and DNMT3A mutations in progenitors of patients with angioimmunoblastic T-cell lymphomas (AITL). Here, we report on the cooperative effect of Tet2 inactivation and DNMT3A mutation affecting arginine 882 (DNMT3A(R882H)) using a murine bone marrow transplantation assay...
