Metastatic brain tumors are the most common intracranial neoplasms.¹ Fifteen percent to 30% of patients with cancer develop cerebral metastases during the course of their illness.^2-3 Carcinomas of the lung, breast, colon, and kidney and malignant melanoma are the common primary sources. At the time of neurologic diagnosis, 50% of patients will have a single brain metastasis shown on computed tomographic scan,^4-5 whereas fewer than 30% will have only 1 lesion shown on magnetic resonance imaging, a more sensitive imaging method.⁶ The median survival of untreated patients with brain metastases is approximately 1 month,⁷ although survival time can be doubled by the use of corticosteroids.⁸ When added to corticosteroid treatment, whole-brain radiation therapy may further improve neurologic function with tolerable morbidity, although survival times remain short, ranging from 3 to 6 months.^9-10
