Number of participants that the trial has enrolled


Results

We enrolled 1194 eligible patients. Median overall survival times after stereotactic radiosurgery were 13.9 months [95% CI 12.0&#8211;15.6] in the 455 patients with one tumor, 10.8 months [9.4&#8211;12.4] in the 531 patients with 2-4 tumors, and 10.8 months [9.1&#8211;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&#8211;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.
