A Comparison of Overall Survival Post-CyberKnife Radiosurgery Treatment of Patients With 1-3 Versus 4 or More Brain Metastases
This is registry-based cohort study of patients with brain metastases treated at Stanford
University Medical Center (SUMC) with CyberKnife radiosurgery (CK RS). It has two
components: (1) a retrospective follow-up of patients treated since 2006, and (2) the
accrual of a new cohort of patients treated over a 5-year period from January 15, 2013 to
December 31, 2017 and followed for at least one year thereafter. The primary aim of this
study is to estimate the effect of the number of brain tumor metastases on survival after
adjusting for known risk factors for mortality.
Observational Model: Cohort
until death or the end of follow-up, whichever comes first.
