title: Linear accelerator based intracranial and extracranial stereotactic radiation therapy at the University of Oklahoma.
abstract: OBJECTIVE
  Review our institutional outcomes with linear accelerator based stereotactic radiation therapy at the University of Oklahoma.
  
  
  METHODS
  We retrospectively reviewed all patients treated in our department with linear accelerator based stereotactic radiation therapy since we implemented this modality in 2008. Thirty-seven patients have been treated with a mean follow-up of 8.3 months. Seventeen patients had tumors near critical structures; ten had treatment sites not suited for gamma knife therapy. Outcomes are reviewed for efficacy and toxicity.
  
  
  RESULTS
  Acute and long term complications reported are minimal. Stabilization of treatment sites was achieved in 96% of patients on follow-up imaging. Thirteen patients (35%) have died, of which eleven died to systemic disease progression outside of the treatment site. No treatment related deaths occurred.
  
  
  CONCLUSIONS
  Stereotactic radiation therapy is a successful treatment modality to achieve local disease control with minimal toxicity. We plan to expand its use and applications in the future.
