Linear accelerator-based stereotaxic radiosurgery for brain metastases:the influence of number of lesions on survival.

Abstract

Survival duration is equivalent for patients with one or two brain metastases and is similar to that reported for patients with a solitary metastasis managed by surgical resection and whole-brain irradiation. Survival after radiosurgery for three or more metastases was similar to that reported for whole-brain irradiation.
