Other marrow failure diseases
Transplant advances and outcomes
Bone marrow failure syndromes are rare diseases with abnormal or absent hematopoiesis in one or more cell lines. They include acquired or congenital aplastic anemia, Fanconi anemia and Diamond-Blackfan anemia. Most patients are diagnosed in childhood and commonly present with hematologic findings such as single-cell or pancytopenia, myelodysplastic syndromes or leukemia, particularly acute myeloid leukemia. [1]
Diamond-Blackfan and Fanconi anemia are rare heterogeneous disorders characterized by red cell aplasia. Many patients eventually develop pancytopenias from these syndromes. Allogeneic hematopoietic cell transplantation (HCT) offers the only potential cure for both disorders. [1,4] A 2016 study of long-term survival in patients transplanted for Fanconi anemia found that 10 and 15-year probabilities of survival were 90% and 79%, respectively. [5]
Recommended timing for transplant consultation
- Diamond-Blackfan Anemia: continued transfusion dependent anemia following a course of steroid therapy, development of significant infections, MDS/AML
- Shwachman-Diamond syndrome, Fanconi anemia, Dyskeratosis Congentia and others: development of cytopenias, transfusion dependence, or significant infections; high-risk cytopenic clones, high-risk somatic mutation patterns; MDS/AML
