Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The need of radiosurgery is controversial for asymptomatic oligo brain metastasis for non small cell lung cancer (NSCLC).

Therefore, the investigators do a randomized study comparing overall survival between two groups with or without radiosurgery for asymptomatic oligo brain metastasis before palliative chemotherapy for NSCLC.
