Uterus transplantation in a non-human primate: long-term follow-up after autologous transplantation

2012

BACKGROUND Uterus transplantation (UTx) may provide the first available treatment for women affected by uterine infertility. The present study aimed to further develop a surgical technique for autologous UTx in a non-human primate species and to assess long-term function. METHODS Female baboons (n= 16) underwent autologous transplantation of the uterus with the Fallopian tubes and ovaries, performed with a previously published surgical technique (n= 6, Group 1) or using a modified technique (n= 10; Group 2). The uterine arteries were dissected to the proximal end of the anterior branch (Group 1) or the entire (Group 2) internal iliac artery, and the ovarian veins were dissected to the cross…

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…

The role of stem cell transplantation in follicular lymphoma.

2017

With the introduction of novel treatments paradigms to if or when to use transplantation strategies for patients with follicular lymphoma have changed substantially. Autologous transplantation has been intensively evaluated as consolidation after first induction treatment with positive effects, however the introduction of Rituximab led to comparable improvements and HDT has been moved to relapse treatment. In this indication HDT was frequently use already at first relapse, but now is dominantly used in patients with a highrisk profile, e.g. failure of response, early or multiply relapse and/or signs of transformation. The ideal place for allogeneic transplantation is even harder to define, …

Impact of different strategies of second-line stem cell harvest on the outcome of autologous transplantation in poor peripheral blood stem cell mobil…

2005

The optimal approach to obtain an adequate graft for transplantation in patients with poor peripheral blood stem cell (PBSC) mobilization remains unclear. We retrospectively assessed the impact of different strategies of second-line stem cell harvest on the transplantation outcome of patients who failed PBSC mobilization in our institution. Such patients were distributed into three groups: those who proceeded to steady-state bone marrow (BM) collection (group A, n = 34); those who underwent second PBSC mobilization (group B, n = 41); those in whom no further harvesting was carried out (group C, n = 30). PBSC harvest yielded significantly more CD34+ cells than BM collection. Autologous trans…

Autologous Transplantation of In Vivo Purged PBSC in CML

2000

To determine the effectiveness of different methods for the detection of tumor cell contamination of collected peripheral stem cells, we performed a study on 39 chronic myelogenous leukemia (CML) patients who were consecutively treated at our department. Analyses of tumor cell contamination by fluorescence in situ hybridization (FISH), conventional cytogenetics, and polymerase chain reaction (PCR) showed marked differences in the percentage of evaluable results: Quantitative analysis of tumor cell contamination was feasible in 60 of 105 (57%) samples evaluated with the use of conventional cytogenetic analysis and in 105 of 107 (98%) samples analyzed by FISH. PCR was evaluable in all 85 samp…

Rituximab combined with DexaBEAM followed by high dose therapy as salvage therapy in patients with relapsed or refractory B-cell lymphoma: mature res…

2014

Summary Salvage therapy followed by high-dose therapy (HDT) remains a mainstay for patients with relapsed lymphoma, however no optimal regimen has been defined. Here we report on the results of R-DexaBEAM (rituximab, dexamethasone, carmustine, etoposide, cytarabine, melphalan) followed by HDT. Patients aged 18–65 years, Eastern Cooperative Oncology Group performance score 0–2, with relapsed/refractory B-cell non-Hodgkin lymphoma (NHL) were eligible. R-Dexa-BEAM was given for two cycles followed by stem cell mobilization and HDT. Primary endpoint of the trial was progression-free-survival (PFS). One hundred and three patients were included: aggressive NHL (aNHL): diffuse large B-cell lymphom…

Survival of elderly patients with multiple myeloma-Effect of upfront autologous stem cell transplantation

2016

Abstract Background The aim of this study was to determine the value of upfront autologous transplantation (ASCT) in elderly patients (60–79 years) with myeloma. Methods We analysed relative survival (RS) of patients diagnosed in 1998–2011 and treated with ASCT within 12 months after diagnosis in Germany (n = 3591; German Registry of Stem Cell Transplantation) and compare RS with survival of myeloma patients diagnosed in the same years in Germany (n = 13,903; population-based German Cancer Registries). Results Utilisation of ASCT has increased rapidly between 2000–2002 and 2009–2011 (60–64years: 7.0–43.0%; 65–69 years: 6.6–23.7%; 70–79 years: 0.4–4.0%). Comparison of 5-year RS of patients f…

Alteration of HSC Functions in Thalassemia

2015

Abstract Beta-thalassemia represents one of the most globally widespread monogenic disorders and is characterized by significantly reduced or absent synthesis of hemoglobin beta-chains. In its severe form the insufficient production of adult hemoglobin results in altered erythropoiesis, hemolytic anemia, bone marrow (BM) hematopoietic hyperplasia and splenomegaly often associated with extramedullary hematopoiesis, requiring regular blood transfusions and iron chelation treatment. Over the last two decades many progresses were made in the field of allogeneic bone marrow (BM) transplantation to definitively cure beta-thalassemia. In parallel, experimental autologous transplantation protocols …

Elotuzumab in Combination with Lenalidomide, Bortezomib, Dexamethasone and Autologous Transplantation for Newly-Diagnosed Multiple Myeloma: Results f…

2021

Abstract Background: Treatment regimens including a proteasome inhibitor, immunomodulating agent and a monoclonal antibody (moAb) play an emerging role in the treatment of newly-diagnosed multiple myeloma (NDMM). This multicenter phase III trial of the German-speaking Myeloma Multicenter Group (GMMG HD6) investigated the addition of the anti-SLAMF7 moAb elotuzumab to lenalidomide / bortezomib / dexamethasone (RVd) in induction and consolidation therapy as well as to lenalidomide maintenance treatment in transplant-eligible NDMM. Patients and Methods: Patients were equally randomized into four treatment arms, stratified by International Staging System (ISS). Treatment consisted of four 21-da…
