European wide survey on allogeneic haematopoietic cell transplantation practice for myelofibrosis on behalf of the EBMT chronic malignancies working party

Heterogeneous practices exist across transplant centres regarding assessment prior to allogeneic haematopoietic cell transplantation (allo-HCT) for myelofibrosis, post-transplant monitoring and management of relapse. The 'Practice Harmonisation and Guidelines' and Myeloproliferative Neoplasms subcommittees of the Chronic Malignancies Working Party (CMWP) of the EBMT generated an electronic survey proposal to investigate approaches to the above aspects of myelofibrosis allo-HCT practice. This survey was sent to a total of 65 centres experienced in allo-HCT for myelofibrosis across Europe in February 2020. By time of survey closure, a total of 36 centres (55 %) had completed the survey. Responses were aggregated and reported in a comparative fashion. Marked variations in assessment prior to alloHCT, JAK inhibitor management peri-transplant, molecular, histopathological and cytogenetic monitoring and approaches to the definition and management of relapse were apparent across surveyed centres. On the basis of these findings, future CMWP efforts will focus on defining guidelines for relapse definition in MF allo-HCT and also suggested optimal monitoring practices for the transplant community.
