Allogeneic stem cell transplantation after conditioning with treosulfan, etoposide and cyclophosphamide for patients with acute lymphoblastic leukemi…

2014

Abstract Total-body-irradiation (TBI) based preparative regimens are considered as standard conditioning therapy for allogeneic stem cell transplantation (AHSC) in patients with acute lymphoblastic leukemia (ALL). Within a multi-center prospective phase II study we have investigated the toxicity and efficacy of a non-TBI-based regimen consisting of treosulfan, etoposide, and cyclophosphamide in patients with ALL. Inclusion criteria were complete remission, non-eligibility for TBI or patient’s wish to avoid TBI. Between July 2007 and August 2010, 50 patients with a median age of 46.5 years were enrolled at ten German centers. 74% of the patients were in 1. CR and 26% 2. or higher CR.The cond…

AUTOLOGOUS HEMATOPOIETIC STEM CELL TRANSPLANTATION (AUTOHSCT) IN CLL: FIRST RESULTS OF AN EBMT RANDOMIZED TRIAL COMPARING AUTOTRANSPLANT VERSUS WAIT …

2010

Abstract Abstract 877 This phase-III randomized EBMT-intergroup trial studied the impact of a consolidating autoHSCT vs no consolidation for patients with CLL in Binet stage A progressive, B or C , in CR, nodular PR or VGPR after first or second line therapy. The primary objective was to show that autoHSCT increased the 5-year progression-free survival (PFS) by 30%. Although it had been calculated that 270 patients were to be randomized, the study was terminated by the steering committee in July 2007 due to poor accrual. Here we present a first analysis based on 69% of expected follow-up forms. Results: Between November 2001 and July 2007, 223 patients were enrolled (SFGM-TC/FCLLG n=98, MRC…

Treatment of Newly Diagnosed Moderate or Severe Chronic Graft-Versus-Host Disease with Prednisone and Everolimus (PredEver first): A Prospective Mult…

2019

Background Chronic graft-versus-host disease (cGVHD) is the major cause of treatment related morbidity and mortality after allogeneic stem cell transplantation (allo-HSCT). Recently Paul Martin et al. reported that treatment success at 1 year (defined as a patient being in partial (PR) or complete remission (CR) of cGVHD, in ongoing remission of underlying disease and not requiring any secondary treatment for cGVHD) was the only endpoint associated with clinical benefit. Strikingly this robust endpoint was only achieved in less than 20% of patients undergoing primary treatment for cGVHD. Therefore, although most patients show initial response to first-line therapy, long-term clinically mean…

All-Trans Retinoic Acid and Gemtuzumab Ozogamicin as Adjunct To Salvage Therapy in Primary Refractory Acute Myeloid Leukemia: Results of Consecutive …

2005

Abstract Introduction: Response to first induction therapy is one of the most important prognostic factors in patients with adult myeloid leukemia (AML). Induction of CR or PR is the primary aim in these patients. Methods: Between 1993 and 2005 225 consecutive patients (median age: 48.4 yrs, range 16–60 yrs) treated within the AMLHD93 (n=45), AMLHD98A (n=157) and AMLSG 05-04 (n=23, still active) trials were evaluated. All patients had primary refractory AML after one cycle of ICE. The different salvage therapies were as follows: AMLHD93 sequential-HAM (S-HAM) for patients <55 years of age [cytarabine 3g/m2 bid. days 1,2,8,9, mitoxantrone 10mg/m2 days 3,4,10,11], HAM for patients >=55 …

Systemic mastocytosis. A GIMEMA multicenter survey

2006

Abstract To evaluate clinical and biological features, treatments and outcome of patients(pts) with Systemic Mastocytosis(SM). A retrospective study (1995–2006) about pts with SM admitted in 14 Italian hematology divisions in tertiary cares or university hospitals. 30 cases of SM were collected(median age 62 y.o.; M/F 14/16) and classified according to the WHO criteria: Mast Cell Leukemia in 14 pts, Aggressive SM in 12 and Indolent in 3; the remaining one had SM with associated clonal non-mast cell-lineage hematologic disease. Skin was the principal extramedullary organ involved (19 pts) followed by spleen(15), liver(13), and cardiovascular system(12). Molecular biology studies were perform…

Immunomodulatory and Hematopoietic Effects of Recombinant Human Interleukin-6 in Patients with Advanced Renal Cell Cancer

1996

Interleukin-6 (IL-6) is a cytokine with pleiotropic biologic activities on B cells, T cells, and hematopoietic progenitors. The present study was undertaken to assess pharmacodynamic effects of subcutaneous administration of IL-6 on blood counts, immunologic parameters, and acute-phase reactants. Blood samples were taken from patients with advanced renal cell cancer participating in a phase II trial of recombinant human IL-6. Multiparameter FACS analyses of peripheral blood mononuclear cells were performed using antibodies against CD3, CD4, CD8, HLA-DR, CD56, CD28, CD38, CD19, sIgM, and sIgG. Serum levels of IL-10, soluble CD23 (sCD23), sCD25, IL-1 receptor antagonist protein (IL-1RA), solu…

Bioengineering Thymus Organoids to Restore Thymic Function and Induce Donor-Specific Immune Tolerance to Allografts.

2015

One of the major obstacles in organ transplantation is to establish immune tolerance of allografts. Although immunosuppressive drugs can prevent graft rejection to a certain degree, their efficacies are limited, transient, and associated with severe side effects. Induction of thymic central tolerance to allografts remains challenging, largely because of the difficulty of maintaining donor thymic epithelial cells in vitro to allow successful bioengineering. Here, the authors show that three-dimensional scaffolds generated from decellularized mouse thymus can support thymic epithelial cell survival in culture and maintain their unique molecular properties. When transplanted into athymic nude …

Hepatocellular Hyperplasia, Plasmacytoma Formation, and Extramedullary Hematopoiesis in Interleukin (IL)-6/Soluble IL-6 Receptor Double-Transgenic Mi…

1998

Cytokines interact not only with membrane anchored receptors, but also with specific soluble receptors which circulate in the bloodstream. In general, soluble cytokine receptors such as soluble tumor necrosis factor receptor, soluble interleukin 1 receptor, and soluble interleukin 4 receptor compete with their membrane-bound counterparts for the ligands and therefore act as antagonists. In contrast, soluble receptors for cytokines of the interleukin-6 (IL-6) family complex with their ligands act agonistically. Interestingly, the complex of IL-6 and the soluble interleukin 6 receptor (sIL-6R) activates target cells that do not express the membrane-bound IL-6R and therefore cannot respond to …

Assessment of Mobilization Cost for Multiple Myeloma Using 2 Different Mobilization Strategies: High-Dose Cyclophosphamide Versus Plerixafor. on Beha…

2016

Abstract Background. Peripheral blood stem cell (PBSC) collection prior to high dose chemotherapy for autologous transplantation (ASCT) is a standard of care, and an attractive alternative to the use of bone marrow cells, for transplantation in Multiple Myeloma (MM). The optimal methodology for mobilizing PBSC has yet to be defined, both G-CSF and GM-CSF can be used; although, the stimulatory effect may be more pronounced when given after high dose cyclophosphamide (usually administered at a dose of 1.5 to 6g/m2 IV for one to two days) and use of Plerixafor, a CXCR4 antagonist (Mozobil®). The latter 2 options are preferred, overall, in France. Indeed, it was shown that the most recent combi…
