title: The role of radiation therapy in the management of childhood craniopharyngioma.
abstract: Between 1965 and 1986, 31 children were treated for craniopharyngioma at the Children's Hospital of Philadelphia. Total removal was attempted in all patients. Some patients received radiation therapy following subtotal removal. Of the patients whose first resection was subtotal, five received radiation and seven did not. Four of the 5 patients who were radiated (80%) are stable (median 89 months, range 42-155 months) and one recurred at 42 months, failed salvage with total removal, and subsequently died of disease. Of the seven who were not irradiated, all had recurrences (median 12 months, range 3-192 months) and one died of disease. Nineteen patients initially had total removal and none received adjuvant radiation. One patient died postoperatively. Of the 18 remaining patients, 6 had recurrences (median 24 months, range 7-100 months) and 12 (66%) are stable (median 42 months, range 9-133 months). One of these stable patients died of endocrine complications 24 months after initial surgery. Fourteen of the 31 patients recurred. Two died with recurrence and one required no further treatment. Eleven had second resections following initial surgical removal. Seven of these 11 went on to receive radiation and four did not. All seven who were radiated are stable (median 33 months, range 1-228 months); whereas 1 of the 4 who were not radiated recurred again at 18 months. This patient had a third resection followed by radiation therapy and is now stable at 20 months. After initial surgery (and before radiation, when given) 26 of 31 patients had panhypopituitarism, 4 had partial deficits, and 1 was normal. Severe diencephalic syndrome, loss of visual acuity, and intellectual deficits were no more frequent in patients treated with total removal, subtotal removal, and in patients who received radiation. We conclude that radiation has an important role following subtotal removal and for salvage treatment after initial surgery. Aggressive attempt at total removal does result in prolonged progression-free survival in some patients. Extensive resections may result in significant mortality and endocrine morbidity. This review suggests that subtotal removal and radiation results in outcomes at least as favorable as treatment with total removal alone.
