High transplant-related mortality associated with haematopoietic stem cell transplantation for paediatric therapy-related acute myeloid leukaemia (t-AML). A study on behalf of the United Kingdom Paediatric Blood and Bone Marrow Transplant Group.

摘要

Paediatric therapy-related acute myeloid leukaemia (t-AML) is rare and the outcome is poor. While allogeneic haematopoietic stem cell transplantation (HSCT) is generally the accepted modality of treatment, data regarding salvage chemotherapy, remission induction, conditioning regimens, transplant-related mortality and outcome is scarce. Between 2000 and2016, 36 children with t-AML were treated in seven UK paediatric HSCT centres. The most common salvage protocol for remission induction was FLAG with or without idarubicin and 28 patients were in complete morphological remission prior to BMT. Only 12 patients survived (33%). Transplant-related mortality (TRM) was the leading cause of death.
