We enrolled 1194 eligible patients. Median overall survival times after stereotactic radiosurgery were 13.9 months [95% CI 12.0–15.6] in the 455 patients with one tumor, 10.8 months [9.4–12.4] in the 531 patients with 2-4 tumors, and 10.8 months [9.1–12.7] in the 208 patients with 5-10 tumors. Overall survival times did not differ between the patients with 2-4 tumors and those with 5-10 (HR 0.97, 95% CI 0.81–1.18 [less than non-inferiority margin], p=0.78; P (non-inferiority) <0.0001). The proportion of patients who had treatment-related adverse event of grade 1-5 did not differ significantly between the two groups, tumor numbers 2-4 and 5-10. Our results show that stereotactic radiosurgery without WBRT in patients with 5-10 brain metastases is non-inferior to that in patients with 2-4 brain metastases.

The aim of this prospective study is to evaluate results of gamma knife surgery for brain metastases using a standard protocol for indication, dose planning, and follow up. These results will demonstrate indication for and limitations of and gamma knife surgery for brain metastases.
