Objective:To observe the efficacy of stereotactic radiotherapy (SRT) in lung cancer patients with brain metastases and explore the nursing for those patients.Methods:From June 2002 to December 2006,43 patients of lung cancer with brain metastases were treated with SRT,8 of them were treated with the association of whole-brain radiotherapy (WBRT) and 6 of them were treated with combination of chemotherapy.During the period of SRT,the patients were applied with active psychological nursing and diet nursing.We also tried to prevent patients from epicranium injury,and meanwhile,patients were asked to took active convalesce exercise.Results:All patients finished SRT without serious reaction and complication.Local control rate was 81.4%,nervous system symptoms relief rate was 76.7% and KPS score was raised significantly.Survival time ranged from 2 to 34 months,median survival time was 8.5 months,and 6-month,1-and 2-year survival rates were 58.9%,26.2%,and 6.0% respectively.Conclusion:SRT was one of the effective palliation treatments for the lung cancer patients with brain metastases,and with the assistance of effective nursing,which would prolong their survival time and improved quality of life.
