Impact of Donor-Recipient Histocompatibility and CMV-Mismatch on Outcome of Allogeneic Stem Cell Transplantation for AML and MDS: A Retrospective Registry Study of the German Stem Cell Transplant Registry (DRST) of the German Working Group for Blood and Marrow Transplantation (DAG-KBT)
Abstract Introduction Allogeneic stem cell transplantation (allo-SCT) is a curative treatment for several hematological diseases. Donor-recipient histo-incompatibility is associated with poorer outcome. Transplant outcome of CMV positive patients is reported to be poorer, if the unrelated donor is CMV negative (CMV-mismatch). Recent developments in transplant strategies including high resolution HLA-typing, toxicity-reduced conditioning regimens, CMV-monitoring, and improved supportive care have made transplants from HLA- as well as CMV- mismatched unrelated donors more feasible. We present a retrospective registry analysis from a large, and recent cohort of patients transplanted under thes…
Relative Impact of HLA Matching and Non-HLA Donor Characteristics on Outcomes of Allogeneic Stem Cell Transplantation for Acute Myeloid Leukemia and Myelodysplastic Syndrome
Increasing donor-recipient HLA disparity is associated with negative outcomes of allogeneic hematopoietic stem cell transplantation (HSCT), but its comparative relevance amid non-HLA donor characteristics is not well established. We addressed this question in 3215 HSCTs performed between 2005 and 2013 in Germany for acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Donors were HLA-matched related (MRD; n = 872) or unrelated (10/10 MUD, n = 1553) or HLA-mismatched unrelated (10/10 MMUD, n = 790). Overall survival (OS) was similar after MRD compared with 10/10 MUD HSCT, reflecting opposing hazards of relapse (hazard ratio [HR], 1.32; P.002) and nonrelapse mortality (HR, .63; P.0…
Treosulfan or busulfan plus fludarabine as conditioning treatment before allogeneic haemopoietic stem cell transplantation for older patients with acute myeloid leukaemia or myelodysplastic syndrome (MC-FludT.14/L): a randomised, non-inferiority, phase 3 trial
Background: Further improvement of preparative regimens before allogeneic haemopoietic stem cell transplantation (HSCT) is an unmet medical need for the growing number of older or comorbid patients with acute myeloid leukaemia or myelodysplastic syndrome. We aimed to evaluate the efficacy and safety of conditioning with treosulfan plus fludarabine compared with reduced-intensity busulfan plus fludarabine in this population. Methods: We did an open-label, randomised, non-inferiority, phase 3 trial in 31 transplantation centres in France, Germany, Hungary, Italy, and Poland. Eligible patients were 18–70 years, had acute myeloid leukaemia in first or consecutive complete haematological remissi…
