Management of brain metastases.
Brain metastases are common and often occur in patients whose systemic cancer is quiescent. When brain metastases occur, they considerably decrease the quality of life in patients who otherwise might be functional. An early diagnosis and vigorous treatment of the brain metastasis, while only rarely curative, may lead to a useful remission of the brain symptoms and may both enhance the quality of the patient's life and prolong survival. Patients with known cancer and neurological symptoms should all undergo appropriate diagnostic tests which include either CT scan or magnetic resonance imaging and, if a lesion is found and a definitive diagnosis can not be established, biopsy. Single or solitary brain metastases in patients with good systemic performance status should be strongly considered for surgical extirpation which will both make the diagnosis and deliver definitive treatment to the lesion. Patients with poor systemic performance status and/or multiple brain metastases are candidates for whole brain radiation therapy. Whole brain radiation therapy is also indicated in patients after successful surgical extirpation of a single metastasis. The role of focal radiation therapy and chemotherapy in the treatment of brain metastases is still being evaluated. Preliminary evidence suggests that focal radiation therapy is probably useful for the treatment of relapsed metastases and that chemotherapy may be useful in the primary treatment of small or asymptomatic brain metastases. Appropriate use of therapeutic modalities directed at brain tumors will ameliorate symptoms in most patients and usually increase survival and enhance the quality of the patient's life.
