BACKGROUND/AIM: Tacrolimus is an essential immunosuppressant for successful allogeneic haematopoietic stem cell transplantation (Allo-HSCT). This study aimed to examine the change in the blood concentration of tacrolimus during switching from intravenous to oral administration in allo-HSCT for paediatric cancer to predict the optimal dosage. PATIENTS AND METHODS: We retrospectively examined the medical records of 63 patients who received allo-HSCT and were administered tacrolimus. To compare bioavailability among different dose ranges, the blood concentration was divided by the dose (C/D). RESULTS: Thirty-nine patients (age range=children 1-15 years, adults 17-67 years) were switched to oral administration of tacrolimus. The C/D after switching was significantly lower in children than in adults (p=0.039). There was a strong positive correlation between age and C/D in children, whereas no correlation was observed in adults. CONCLUSION: In paediatric cancer patients, switching tacrolimus administration route may result in reduced blood concentrations. This tendency is more prominent in younger children.
