Background: It is well known that survivors of acute lymphoblastic leukemia (ALL) show a tendency to become overweight. Cranial irradiation (CRT), is considered to be the primary risk factor for development of obesity. Aims: The aim of our study was to evaluate body mass index (BMI) and serum leptin levels in survivors of childhood ALL. Methods: Subjects (Group I) consisted of 93 survivors of childhood ALL (53 males ≥ 9 years old, 40 females ≥8 years old) diagnosed between January 1975 and December 2002 in the Hematology-Oncology Division in Cerrahpasa Medical Faculty, Istanbul University after a follow up 10.21±4.90 (mean ± SD) years. Fifty healthy individuals of similar chronological age were taken as controls (29 males, 21 females). Seventy-four subjects had received radiotherapy (Group IA) and 19 had not (Group I B). Results: In Group I, BMI was significantly higher than in Group II (21.65±4.02 vs 20.31±3.49, p=0.04). However, BMI was significantly higher only in Group I A (21.83±4.27) than in Group II (p=0.032). Leptin levels were significantly higher in Group I A females than in Group II females. There was a significant correlation between BMI-SDS and serum leptin levels in group IA females. Conclusions: Leukemia treatment leads to obesity. Higher leptin levels in girls may suggest that sex may be a differentiating factor for this late effect. © Freund Publishing House Ltd.
