Recurrence of the original brain metastasis was defined as thereappearance of a metastasis in the exact site in the brain as the first brainmetastasis.

The radiation group (white squares) had amedian survival of more than 115 weeks, and the observation group (black circles)had a median survival of 81 weeks (relative risk of death from neurologiccauses, 2.62; 95% confidence interval, ). Length of survival wasmeasured from the beginning of treatment for the original brain metastasis.Tick marks indicate patients who did not die of neurologic causes or the lastfollow-up evaluation in living patients.
