Inferior outcomes for overweight children undergoing allogeneic stem cell transplantation

This retrospective cohort study aimed at determining whether overweight children undergoing allogeneic stem cell transplantation (SCT) had inferior overall survival compared with children who were not overweight. Children >/=2 years of age who received allogeneic SCT were included. Overweight was defined as a body mass index >/= 95th percentile; 54/325 (17%) children were overweight. Overall survival at 5 years was significantly inferior at 46.6 +/- 7.3% in the overweight group compared with 59.5 +/- 3.2% in the non-overweight group (P = 0.02). Our study demonstrated that overweight children who undergo allogeneic SCT had inferior survival compared with children who were not overweight.
