Stereotactic body radiation therapy to right-upper-lobe NSCLC

(A) CT of a 76-year old male, former smoker with a 19-mm right-upper-lobe NSCLC. Due to an FEV1 of 0.65 L (23% predicted) and a DLCO of 5.6 (23% predicted), he was not offered surgery and underwent SBRT (5 fractions, 6000 cGy).
(B) CT one year post-SBRT with postradiation changes but no evidence of recurrence.
