Radiosurgery for brain metastases.

Brain metastases represent the most common intracranial neoplasm, and they have become the most common indication for radiosurgery. The authors present a review summarizing the major issues surrounding the management of brain metastases and an English-language literature review of 21 independent reports, using either Gamma Knife or linear accelerator-based radiosurgery, with over 1700 patients and more than 2700 lesions available for analysis.
