Prognostic factors and grading systems for overall survival in patients treated with radiosurgery for brain metastases: variation by primary site

Abstract

Favorable prognostic factors for patients with newly diagnosed brain metastases treated with radiosurgery vary by primary site. The 4 prognostic grading systems analyzed were applicable to different primary sites depending on which prognostic factors each individual system incorporated. Therefore, the authors recommend further development and use of primary-specific prognostic systems.
