Outcomes after stereotactic lung radiotherapy or wedge resection for stage I non-small-cell lung cancer.

PURPOSE To compare outcomes between lung stereotactic radiotherapy (SBRT) and wedge resection for stage I non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS One hundred twenty-four patients with T1-2N0 NSCLC underwent wedge resection (n = 69) or image-guided lung SBRT (n = 58) from February 2003 through August 2008. All were ineligible for anatomic lobectomy; of those receiving SBRT, 95% were medically inoperable, with 5% refusing surgery.
