Radiosurgery for Intracranial Malignancies.
Radiosurgery was historically designed as a technology to be used for the treatment of functional disorders, benign tumors, and vascular malformations. In the last 5 years, malignant lesions have become an increasingly common target for the radiosurgeon. In fact, by 1994 the most common disease treated with radiosurgery in the United States was metastatic disease. Published data suggest that radiosurgery offers excellent local control for intracranial metastatic lesions regardless of location or histology with the majority of patients demonstrating an improved quality of life. Recent information from the Joint Center for Radiation Therapy suggests that radiosurgery compares favorably with interstitial brachytherapy for both recurrent as well as in newly diagnosed patients with malignant gliomas in terms of improved survival and the need of surgery and steroid support for symptomatic radiation changes. Prospective studies (Phase I through III) are ongoing to determine the ultimate role of radiosurgery in the management of patients with newly diagnosed and recurrent malignant gliomas, recurrent pediatric brain tumors disease, and patients with single or multiple intracranial metastases.
