摘要: Abstract Purpose This work describes trends in the utilization and survival benefit of stereotactic radiosurgery (SRS) with respect to geographic region United States year diagnosis among patients NSCLC synchronous brain metastases. Methods Patients metastases (2010–2015) were identified NCDB. Descriptive statistics calculated across case SRS region. Univariable multivariable regression performed identify predictors treatment overall population estimate region-specific models hazard mortality over each year. Results Among 49,048 cases metastases, 8310 treated SRS. Those Middle Atlantic had greatest odds treatment, at 1.03 times those East North Central (95% CI: 1.02–1.04, p  Conclusion Increased was observed decreased five diagnosis-years These suggest clinical burden secondary cancers, particularly will increase years come.
