Abstract
Nine children with brain tumors are described who have received various combinations of treatment, including surgery, radiotherapy, and chemotherapy. Many of the children were noted to be of short stature. Endocrine assessment was carried out from 2 to 10 years after treatment. The combined results of insulin tolerance and Bovril stimulation tests show an impaired growth hormone response in six of the nine children. Bone age is retarded in all cases, and the present height is below the 10th percentile in five of the six. The cause of this growth hormone deficiency is obscure, but further studies are in progress.
