Successful hematopoietic reconstitution by unrelated donor cord blood transplantation in children with Fanconi anemia: report of 3 cases

Abstract

To potentially reduce late effects of malignancy and chronic graft-versus-host disease in patients with Fanconi anemia, 3 patients received unmanipulated umbilical cord blood grafts with 0 or 1 HLA antigen mismatch. The conditioning regimen consisted of fludarabine (30 mg/m/d) for 6 days, cyclophosphamide (60 mg/kg/d) for 2 days, and rabbit antithymocyte globulin (ATG) (2.5 mg/kg/d) for 3 days. Radiation was not used in the preparative regimen. None of the patients had significant conditioning-related toxicity. All were engrafted within 10 to 19 days. All patients are well with stable or full donor chimerism after a median follow-up of 64 months (range, 13 to 69 mo).
