Abstract:
The aim of this study was to analyze the outcomes of children with Diamond‐Blackfan anemia (DBA) treated in Brazil with hematopoietic cell transplantation (HCT). Methods We performed a retrospective analysis of 44 pediatrics patients transplanted between 1990 and 2018. The median age of patients was 5 years, and 57% were male. Twenty‐five received their first HCT from an HLA‐matched sibling donor (MSD), 12 from a HLA matched unrelated bone marrow donor (MUD 10/10, n = 12) and 7 other HLA mismatched donors (MMD). Results After a median follow‐up of 4 years, estimate 5‐year overall survival (OS) for the entire cohort was 70%, 80% for MSD group, 73% for MUD, and 29% for MMD. Thirty‐eight out of the 44 evaluable patients engrafted successfully. Primary and secondary graft failure was observed in five and three patients, respectively. Rates of grade II‐IV and III‐IV acute graft‐versus‐host disease (aGVHD) were 25% and 18%, respectively. Nine patients developed chronic GVHD (cGVHD). Conclusion Overall survival rates observed after HLA matched donors transplant for DBA were comparable to those reported from higher‐income countries and international registries.
