Trends in Allogeneic Stem Cell Transplantation for Myelofibrosis in Europe between 1995-2018: An EBMT Retrospective Analysis

Aim: Dynamic assessment of trends over time in patient- and transplant-specific characteristics and outcomes for patients undergoing 1st allogeneic haematopoietic cell transplant (allo-HCT) for Myelofibrosis (MF). Methods and Results: A total of 4142 MF patients were analysed who underwent allo-HCT between 1995-2018 (24-year period) across 278 centres based on data reported to the European Society for Blood and Marrow Transplantation. For analysis, 4 cohorts were considered based on year of allo-HCT: 60 years accounted for 8.7% of adults undergoing allo-HCT whereas for 2015-2018 this was 47%. Over time, increasing number of patients with a Karnofsky performance status (KPS) Conclusions: Despite a marked increase over this 24-year period in recipient age, RIC regimen utilisation and use of both URD and MMRD, this comprehensive analysis demonstrates stable OS and EFS rates. However, rates of GVHD have decreased over time, in particular extensive cGVHD. Further work is required to improve both the considerable NRM and relapse rates which remain significant.
