Busulfan/Fludarabine- or Treosulfan/Fludarabine-Based Conditioning Regimen for Patients with Wiskott-Aldrich Syndrome – an EBMT Inborn Errors Working Party and Scetide Study

Introduction Excellent survival rates have been reported after allogeneic haematopoietic stem cell transplantation (HSCT) for Wiskott-Aldrich syndrome (WAS) patients. Recipient age >5 years in MUD HSCT as well as MMFD as donor were negative predictors for outcome. However, the vast majority of HSCTs in previously published studies were performed with (oral) busulfan/cyclophosphamide-based conditioning and in the early 2000 years or before. Objectives To compare OS and EFS after HSCT with either busulfan/fludarabine (BuFlu) ± thiotepa (TT) or treosulfan/fludarabine (TreoFlu) ± TT as recommen... Mehr ...
