Management of brain metastases.

Brain metastases represent a common and devastating complication of cancer. With advances in surgery, radiology, and medical and radiation oncology, the number of treatment options have greatly increased. In addition, the prognosis for patients can vary widely depending on factors such as the number of lesions, extent of extracranial disease, age, and functional status. Recently, the possible impairment of whole brain radiation therapy on neurocognitive function has been a subject of concern and debate. Thus, the use of whole brain radiation therapy in conjunction with other treatment modalities should be optimized to ensure the best outcomes with regard to tumor control and functional status. As a result, patient management has become controversial, with strong opinions often dictating "optimal" therapy. This review of the management of brain metastases focuses on whole brain radiation therapy, surgery, stereotactic radiosurgery, radiation sensitizers, and clinical trials.
