Objective To investigate the feasibility and clinical value of combined treatment for lung cancer with cerebral metastasis. Methods From May 1999 to May 2005, twentyone patients diagnosed lung cancer with cerebral metastasis received treatment in our hospital. The management consists of cerebral lesion resection, chemotherapy, lung cancer resection and chemotherapy or radiotherapy. Then evaluate the short-term and long-term outcome. Results No severe complications occurred in hospital. The 1-, 2-, and 3-year survival rates were 75.0%(12/16), 37.5%(6/16), and 12.5%(2/16) respectively. Life quality was promoted significantly. Conclusion Although lung cancer with cerebral metastasis is classified as stage Ⅳ,the effect of combined treatment is favorable because of the special metastatic position. But the choice of the patient is important.
