ReviewTreatment options for brain metastases in patients with non-small-cell lung cancer.
Brain metastases are a common complication for patients with non-small-cell lung cancer and a significant cause of morbidity and mortality. In the past, treatment of brain metastases and lung cancer focused on symptom palliation with whole-brain radiotherapy (WBRT) and steroids because of the grim outlook for patients. However, recent advances in technology and surgical techniques have created more options for the management of brain metastases, which include surgery, irradiation, stereotactic radiosurgery, and chemotherapy. ⋯ For patients with multiple metastases, WBRT is recommended. For patients with oligometastatic disease and those with multiple metastases, recent evidence indicates that systemically effective chemotherapy may produce responses and can be instituted safely before radiotherapy. The treatment timing of chemotherapy and radiotherapy should be individualized.

Low-dose CT screening for lung cancer is a complex and controversial topic. This article reviews the history of lung cancer screening trials and addresses the principles and confounding biases associated with screening. Chest radiography was initially used for lung cancer screening in the 1970s. ⋯ Results from prevalence studies and a few single-arm incidence studies have raised concerns about overdiagnosis and the high rate of nodule detection. Follow-up studies and further investigation are needed. To this end, a randomized, controlled trial sponsored by the National Cancer Institute is underway to evaluate disease-specific mortality.
