Summary Allogeneic haematopoietic stem cell transplantation ( HSCT ) is the only curative option for patients with Diamond Blackfan anaemia ( DBA ). We report the transplantation outcome of 30 Italian DBA patients referred to the Italian Association of Paediatric Haematology and Oncology Registry between 1990 and 2012. This is one of the largest national registry cohorts of transplanted DBA patients. Most patients (83%) were allografted after 2000. A matched sibling donor was employed in 16 patients (53%), the remaining 14 patients (47%) were transplanted from matched unrelated donors. Twenty‐eight of the 30 patients engrafted. One patient died at day +6 due to veno‐occlusive disease without achieving neutrophil recovery and another patient remained transfusion‐dependent despite the presence of a full donor chimerism. The 5‐year overall survival and transplant‐related mortality was 74·4% and 25·6%, respectively. Patients younger than 10 years as well as those transplanted after 2000 showed a significantly higher overall survival and a significantly lower risk of transplant‐related mortality. No difference between donor type was observed. Our data suggest that allogeneic HSCT from a related or unrelated donor was a reasonable alternative to transfusion therapy in young and well chelated DBA patients.
