Intermediate-dose busulfan and cyclophosphamide as a conditioning regimen for bone marrow transplantation in a case of Fanconi anemia in myelodysplastic transformation

We report an 11-year old female with myelodysplastic (refractory anemia with excess of blasts) presentation of Fanconi anemia. After failure of initial chemotherapy with low doses of 6-mercaptopurine and prednisolone she underwent allogeneic bone marrow transplantation (BMT) from her HLA-matched sibling. Busulfan 8 mg/kg and cyclophosphamide 40 mg/kg were used as conditioning. The post-transplant course was uneventful with fast trilineage engraftment and mild cutaneous acute GVHD. She is alive 17 months after BMT with full hematological reconstitution without evidence of MDS.
