1 S L I D E 0 Elderly Patients Undergoing SBRT for Inoperable Early Stage NSCLC Achieve Similar Outcomes to Younger Patients Brandon R. Mancini, Henry S. Park, Eileen Harder, Charles E. Rutter, Christopher D. Corso, Roy H. Decker, Zain A. Husain Session title: (DPD 01) Lung 1 - Novel Prognostic Factors and SBRT Session date: September 14, 2014 Abstract number: 1520

2 S L I D E 1 Background / Methods Purpose/Objective(s): To address toxicity and survival achieved with SBRT in the elderly compared to younger patients treated at the same institution. Materials/Methods: –Patients diagnosed with T1-3N0M0 NSCLC treated with SBRT between Sep 2007 and Aug 2013. –SBRT was delivered in 3-5 fractions to 40-60 Gy, with a vast majority of patients receiving 54 Gy in 3 fractions. –Patients were divided into two cohorts, age >75 and <75. –We compared overall survival (OS) and local recurrence-free survival (LRFS) between cohorts.

7 S L I D E 6 Conclusions To our knowledge, this is the largest single institution study to date evaluating safety and efficacy of SBRT in an elderly population. In our series, elderly patients undergoing SBRT appear to have achieved similar outcomes and toxicity compared to younger patients.
