Allogeneic Stem Cell Transplantation for Acquired Aplastic Anemia: Better Outcome with Bone Marrow as Compared to Peripheral Blood in HLA-Matched Sib…
2009
Abstract Abstract 876 Background: Transplantation of bone marrow (BM) from a HLA-matched sibling donor is an effective treatment for severe aplastic anemia (AA) with long-term survival in excess of 80%. In the recent years there were two trends in allogeneic stem cell transplantation (SCT) for AA: (1) increasing proportion of transplants performed from matched unrelated donors (MUD) and (2) increasing proportion of transplants using peripheral blood progenitor cells (PBSC) as stem cell source instead of BM. A similar switch to PBSC over BM grafts is reported in leukemia transplants. PBSC grafts for leukemia are associated with higher rates of chronic graft-versus-host disease (cGVHD). This …
Related versus unrelated donor transplantation for high risk (HiRi) acute myeloid leukemia (AML) in first complete remission (CR1)
2007
Abstract Allogeneic hematopoietic stem cell transplantation (allo-SCT) from an HLA-identical sibling donor (SIB) is considered the preferred postremission therapy for younger patients with HiRi AML in CR1. The role of allo-SCT from volunteer unrelated donors (VUDs) is less clear and randomized controlled trials addressing this issue do not exist. We performed an observational landmark analysis on parallel cohorts of patients aged <60 years with AML in CR1 and HiRi cytogenetics who had been enrolled into the AML Cooperative Group (AMLCG) 1999 trial. 2347 patients were evaluable for the present update. 243/2347 patients were <60 years of age and had unfavorable cytogenetics [com…
Chronic graft-versus-host disease: long-term results from a randomized trial on graft-versus-host disease prophylaxis with or without anti-T-cell glo…

Abstract Previous randomized graft-versus-host disease (GVHD)-prophylaxis trials have failed to demonstrate reduced incidence and severity of chronic GVHD (cGVHD). Here we reanalyzed and updated a randomized phase 3 trial comparing standard GVHD prophylaxis with or without pretransplantation ATG-Fresenius (ATG-F) in 201 adult patients receiving myeloablative conditioning before transplantation from unrelated donors. The cumulative incidence of extensive cGVHD after 3 years was 12.2% in the ATG-F group versus 45.0% in the control group (P < .0001). The 3-year cumulative incidence of relapse and of nonrelapse mortality was 32.6% and 19.4% in the ATG-F group and 28.2% and 33.5% in the contr…
Influence of molecular subgroups on outcome of acute myeloid leukemia with normal karyotype in 141 patients undergoing salvage allogeneic stem cell t…
2012
Based on molecular aberrations, in particular the NPM1 mutation (NPM1(mut)) and the FLT3 internal tandem duplication (Flt3-ITD), prognostic subgroups have been defined among patients with acute myeloid leukemia with normal karyotype. Whereas these subgroups are known to play an important role in outcome in first complete remission, and also in the indication for allogeneic stem cell transplantation, data are limited on their role after transplantation in advanced disease. To evaluate the role of molecular subgroups of acute myeloid leukemia with normal karyotype after allogeneic stem cell transplantation beyond first complete remission, we analyzed the data from 141 consecutive adults (medi…
