Brief Summary
The purpose of this study is to estimate the rate of local control at the treated site of the metastasis as a function of 1mm versus 3mm expansion about the gross tumor volume (GTV). Each lesion, not each patient will be ranndomized to either the 1mm or 3mm margin with 40 lesions randomized to each arm.

Outcome Measures
Primary Outcomes (1)
12-month Local Control Rate
The 12-month local control rate is the percentage of lesions without recurrence at the lesion site 12 months after SRS. Time to local recurrence was defined as the time between SRS and local recurrence. If local recurrence did not occur, the time to local recurrence was censored at last follow-up (including deaths without local recurrence). Kaplan-Meier methods were used to describe the time to local recurrence.
12 months after SRS
Secondary Outcomes (7)
Rate of Radionecrosis at SRS Treatment Site
24 months after SRS
12 Month Rate of Distant Brain Metastases
12 month after SRS
Median Overall Survival
