title: Pubertal development and final height after autologous bone marrow transplantation for acute lymphoblastic leukemia.
abstract: We describe pubertal development and growth in 17 children who underwent bone marrow transplantation (BMT), including total body irradiation (TBI) for ALL. Seven children also received cranial irradiation (CI) and five boys testicular irradiation. All underwent transplantation before (n=15) or at the beginning of (n=2) puberty and reached a final height (FH). Puberty started spontaneously in all boys not given testicular irradiation. All boys who received testicular irradiation developed hypergonadotrophic hypogonadism. Puberty started spontaneously in two girls and was induced with increasing doses of ethinylestradiol in two girls. In two girls, a low dose of ethinylestradiol was given until menarche. In one girl with early onset of puberty and short stature, puberty was blocked with a GnRH analogue. The standard deviation score for height decreased significantly from BMT to FH, both in the children who received TBI only (-1.1, P=0.005) as well as in those given additional CI (-1.7, P=0.027). Most of the loss occurred during puberty. In all, 10 children received growth hormone (GH) treatment. CI, young age at BMT, and short duration of GH treatment were predictors of height loss after BMT. Although limited by the small and heterogeneous sample, our study supports the use of early GH treatment in children with decelerating growth rate and low GH levels.
