Notes:
a
All cases – year 1: n=100 surgery, n=91 SBRT; year 3: n=84 surgery, n=81 SBRT; year 5: n=57 surgery, n=77 SBRT.
b
Propensity-matched cases were matched on age at diagnosis, gender, histology, and any comorbidity. Year 1: n=76 surgery, n=56 SBRT; year 3: n=64 surgery, n=48 SBRT; year 5: n=42 surgery, n=45 SBRT.
Abbreviation: SBRT, stereotactic body radiation.
