Eight children with FA underwent allogeneic HSCT without using irradiation for the conditioning regimen. Patients received two different conditioning regimens: first two patients received BU 1.5 mg/kg/day for four days and CY 10 mg/kg/day for four days and the other regimen was: Flu 30 mg/m 2 /day for five days, CY 10 mg/kg/day for two days, and ATG‐Fresenius 9–10 mg/kg/day for four days. GVHD prophylaxis consisted of CsA + MTX for the first two patients and only CsA for the others. All patients received HLA‐identical stem cells from related donors. Primary engraftment was demonstrated in all patients. No patient developed acute GVHD and one patient had chronic GVHD. Only one patient who received BU based regimen died because of VOD. Overall, seven patients (87.5%) are alive with stable full donor chimerism at a median follow‐up time of 2.5 yr (range: 1.7–8.9 yr). None of the patients developed secondary malignancy. Based on our data, we conclude that Flu‐based, non‐irradiation conditioning regimen was safe with low organ toxicity and stable engraftment in FA patients undergoing HSCT from matched related donors.
