title: Resection versus radiosurgery for patients with brain metastases.
abstract: Brain metastases occur in 20-40% of adult cancer patients and the incidence is apparently increasing. Despite advances in treatment, the prognosis of these patients is poor, with a median survival of approximately 4 months. Whole brain radiation therapy is the standard of care for most patients with brain metastases. Randomized trials have demonstrated that focal treatments, such as resection and radiosurgery, yield significant improvement in the survival of patients with a single metastasis. The utility of these strategies, specifically in terms of increased survival, is unclear in patients with more than one metastasis. In addition to focal treatments, future directions in the treatment of brain metastases include the development of intraoperative imaging capabilities, improved methods of identifying patients who are likely to benefit from treatment, systemic agents, such as chemotherapy and radiosensitizers, and the incorporation of targeted and antiangiogenic therapies.
