Aim:
Herein, we compare outcomes in patients treated with lung stereotactic body radiotherapy (SBRT) with and without tissue confirmation.
Methods:
We reviewed 196 patients that underwent lung SBRT for presumed (100 patients) or proven non-small-cell lung cancer (96 patients) over a 10-year period and compared outcomes.
Results:
A total of 196 patients with a median age of 76 underwent lung SBRT to a median dose of 48 Gy in four fractions. Median follow up was 17 months. Local control and overall survival at 3 years was 94 and 58% for the entire group. There was no difference in overall survival, local control, regional control or distant control between the cohorts.
Conclusion:
SBRT is a safe and effective treatment for patients with non-small-cell lung cancer that are medically inoperable with comparable results in empirically treated patients.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
