Methods： Between 1995 and 2002, 53 patients underwent resection of both primary non-small cell lung cancer and the associated single brain metastasis. There were 33 men and 20 women with a mean age of 57 years （range, 32-85 years）. At the time of diagnosis, 42 patients experienced lung cancer related symptoms, whereas 11 patients experienced brain metastases-related symptoms. 42 patients had received thoracic surgery first, and 11 patients had undergone neurosurgery or radiosurgery first. Pneumonectomy was performed in 9 out of 42 patients （21.4%）, lobectomies in 30 （71.4%）, and wedge resection in 3 （7.2%）. 48 patients （90.5%） underwent complete lymphadenectomy. 35 patients underwent brain metastasectomy. 18 underwent SRS. Results： There was no postoperative mortality and severe complications after either lung or brain surgery. Histology showed 34 adenocarcinomas, 16 squamous cell carcinomas, and 3 large cell lung cancers. 15 patients （28.3%） had no evidence of lymph node metastases （No）, 20 patients （37.7%） had hilar metastases （N1）, and 18 patients （34%） had mediastinal metastases （N2）. The 1-, 2-, 3- and 5-year overall survival rates were 49%, 19%, 10%, and 5%, respectively. The corresponding data for neurosurgery group were 55%, 17%, 11%, and 6%, respectively. The median survival time was 13 months. For SRS group the corresponding data were 44.8%, 20.9% 10.5%, and 2%, respectively. The median survival time was 14 months. The differences between the two groups were not significant （P〉0.05）. In lymph node negative patients （No）, the overall 5-year survival rate was 10%, as compared with a 1% survival rate in patients with lymph node metastases （N1-2）. The difference was significant （P〈0,01）. For adenocarcinomas, the 5-year survival rate was 5%. The correspondent data for squamous cell lung cancers was 3%. The difference was not significant （P〉0.05）. Conclusion： Although the overall survival rate for patients who have brain metastases from NSCLC is poor, surgical resection or radiosurgery may be beneficial in a select group of patients with synchronous brain metastases and lung cancer without lymph node metastases.展开更多

The prognosis of non-small-cell lung cancer(NSCLC) patients with brain metastasis is generally poor and more effective treatment is required to improve their prognosis. Whole-brain radiotherapy, surgery, stereotactic radiosurgery, chemotherapy and targeted therapy are the main treatment for brain metastasis. This review focuses on the five therapeutic strategy and in particular, on targeted therapy.展开更多
