Abstract: Objective To assess the evaluation of SRT (Stereotactic radiotherapy ) and 3D-CRT (Three-dimensional conformal ra-diotherapy)on treatment of brain metastasis from lung cancer .Methods From June 2009 to June 2011 ,74 patients with multiple brain metastasis(brain metastasis ≤3 ,tumor mass ≤3 cm) from lung cancer were analyzed retrospectively ,37 patients received 3D-CRT alone were retrospectively compared with 37 patients who received SRT alone .the results was evaluated by median survival time(MS) ,local control(LC) and toxicity effect .Results The median survival time(MS) was 9 .3 ,which 8 .6 months after 3D-CRT ,and 10 .6 months after SRT .the local control rate was 73 .5% for 3D-CRT ,and 79 .6% for SRT after 3 months .there was no difference between two groups on toxicity effect from stastic .Conclusion The SRT was a efficacious methods for the treatment of brain metastasis from lung cancer ,which could improve the local control rate ,but there was no more toxiticy .
