title: Prepubertal growth and growth hormone secretion in children after treatment for hematological malignancies, including autologous bone marrow transplantation.
abstract: Prepubertal growth standards were used to assess growth in 20 children who had undergone autologous bone marrow transplantation (ABMT) as part of their treatment for hematological malignancy. Most of the patients (16 of 20) were transplanted after a relapse of their disease. A negative change in height standard deviation score (H-SDS) was seen only in the group of patients (n = 7) who had received both cranial irradiation therapy (CRT) and 7.5-Gy single-fraction total body irradiation (TBI). Height changes in this group were observed from the time of diagnosis. In contrast, the groups of patients conditioned with chemotherapy only (n = 3) or both chemotherapy and TBI, without preceding CRT (n = 10), did not demonstrate a significant loss in H-SDS. Weight related to height demonstrated large individual differences over time. Spontaneous growth hormone (GH) secretion, as measured by a four-point sleep curve, was followed longitudinally and an increasing proportion of patients with low peak levels was seen in all patient groups. In summary, prepubertal growth was suppressed only in patients who received cranial irradiation before ABMT. Despite low GH peak levels, normal prepubertal growth was found in patients with no CRT before ABMT.
