Endocrine function in children with intrasellar and suprasellar neoplasms: before and after therapy.

The records of 23 children with intrasellar and suprasellar neoplasms were reviewed for the results of endocrine evaluations before and after treatment with surgery, irradiation, and/or chemotherapy. Deficiency of at least one pituitary hormone was present in 13 patients before treatment and in 22 patients after treatment. Growth hormone deficiency, the most common endocrine abnormality in the pretreatment period, was present in 12 of 17 patients before treatment and in 17 of 21 patients after treatment. In the posttreatment period, thyroid-stimulating hormone deficiency was as common as growth hormone deficiency and was found in 17 of 21 patients evaluated. Hypothalamic-pituitary-gonadal dysfunction and deficiencies of adrenocorticotropic hormone and antidiuretic hormone also occurred in both the pretreatment and posttreatment periods, but were less common.
