Gamma-Knife Radio Surgery in Brain Metastasis

Brain Metastasis (BM) is the most common type of intracranial malignancies in adult. Lung, breast cancer and melanoma are the malignancies which contribute up to 80% of BM [1]. Until recently, the median overall survival for patients with BM has been troubled, and in general the expected survival is at most 6 months after diagnosis [2]. However, owing to the advance of sensitive imaging modalities and various effective treatment strategies, the prognosis of patients with BM, at least in a selected group of patients, had become better.
