There is no consensus as to the optimal treatment of newly diagnosed craniopharyngioma. Little data exist to compare the different modalities in terms of recurrence rate or quality of...
The selection of treatment for patients with nonfunctioning (endocrine-inactive) tumors will depend on tumor size, the progressive course of the disease, and anatomical structures affected by the tumor extension. The majority of patients present with suprasellar extension and visual field deficits. In addition, many have hormone deficits prior to treatment. The initial treatment of patients with gonadotroph adenomas is usually by transsphenoidal surgery, particularly if the adenoma presents with neurological symptoms, because the effect of radiation therapy occurs too slowly, and no reliable medical therapy exists.
Surgical management is typically considered the first choice of treatment for patients with endocrine inactive pituitary adenomas because of its effectiveness in ameliorating symptoms of chiasmal compression and headache. Radical removal of the tumor, however, is difficult to obtain because of the frequent invasiveness into the cavernous sinus. Seventy percent to 80% of patients experience normalization or improvement of visual field defects, and almost 100% of patients with headache as a presenting symptom experience relief. Regrowth of the tumor after radiologically confirmed gross total removal appears to be uncommon. In a series of 32 patients, only 2 (6.2%) with gross total tumor removal and no postoperative radiation therapy showed radiological recurrence of the tumor at a mean follow-up of 5.5 years.
Radiation therapy has been administered routinely in the postoperative period and after clear radiological evidence of residual or recurrent tumor has been demonstrated.[1,2,3] Drug therapy appears to be of limited value.[1,2,3]
