Radiosurgery at the Royal Adelaide Hospital: the first 4 1/2 years' clinical experience

Radiosurgery refers to the treatment of small lesions localized by stereotactic technology using highly focused radiation. This review utilizes prospectively gathered data from the Royal Adelaide Hospital Radiosurgery unit to summarize experience with the first 62 patients (65 lesions) treated between November 1993 and May 1998. This experience included acoustic neuromas (23 patients), arteriovenous malformations (18), brain metastases (12), meningiomas (6), and glomus tumour, subependymoma, dural arteriovenous fistula (1 each). Although follow up is relatively short, the outcome in terms of morbidity and tumour control is thus far comparable with results reported in the literature. Radiosurgery provides a viable alternative to neurosurgery and conventional external beam radiotherapy for several benign and malignant intracranial lesions.
