Objective:To analyze the effects of surgery

radiotherapy combined with chemotherapy for treating lung cancer patients with brain metastasis.Methods:60 lung cancer patients with brain metastasis certified by brain CT and/or MRI

pathology were retrospectively analyzed between January

1999 and December

2005.Results:The median survival time was 12 months for surgery combined with radiotherapy and chemotherapy group and 11 month for radiotherapy combined with chemotherapy group

respectively.The 1-year survival rate was 25.0% and 21.8% respectively.The median survival time was 5 months in pure radiotherapy group and 6 months in pure chemotherapy group

The 1-year survival rate was 7.69% in pure radiotherapy group and 0% in pure chemotherapy group.There was statistically significant difference(P < 0.05)between them.Conclusion:The colligational therapy basing on radiotherapy is more effective

which could elongate the survival time and improve the effects.
