ObjectiveStereotactic body radiotherapy is the standard treatment for medically inoperable early-stage non-small cell lung cancer. Recent data suggest that in operable patients, stereotactic body radiotherapy produces outcomes comparable to those of surgical resection. In veterans with early non-small cell lung cancer, we compared the outcomes of stereotactic body radiotherapy and video-assisted thoracoscopic lobectomy.MethodsWe retrospectively reviewed data from 183 patients (94.0% male) with clinical stage I non-small cell lung cancer who underwent stereotactic body radiotherapy (n = 56) or video-assisted thoracoscopic lobectomy (n = 127) from 2009 to 2014. Propensity matching was used to produce more comparable groups. Primary end points were tumor control and overall, recurrence-free, and lung-cancer-specific survival, as estimated by Kaplan-Meier actuarial analysis. Multivariable analysis was used to identify independent predictors.ResultsIn the overall cohort, the patients who received stereotactic body radiotherapy were older than the patients who received video-assisted thoracoscopic lobectomy (median age, 79.5 vs 64 years) and had more comorbidities. In the 37 propensity-matched pairs, the 3-year actuarial tumor control rate was 54.3% after stereotactic body radiotherapy and 90.6% after video-assisted thoracoscopic lobectomy (P = .0038). Actuarial lung cancer-specific 3-year survival was 78.1% (stereotactic body radiotherapy) versus 93.6% (video-assisted thoracoscopic lobectomy) (P = .055). One-year overall, 3-year overall, and 3-year recurrence-free survivals were 89.2%, 52.9%, and 38.5% after stereotactic body radiotherapy and 94.6%, 85.7%, and 82.8% after video-assisted thoracoscopic lobectomy (P < .005 for all), respectively. In multivariable analysis, stereotactic body radiotherapy independently predicted recurrence and poorer survival.ConclusionsIn veteran patients with early-stage non-small cell lung cancer, video-assisted thoracoscopic lobectomy resulted in better disease control and survival than stereotactic body radiotherapy. Although prior reports suggest that stereotactic body radiotherapy is a suitable alternative to surgery in early-stage lung cancer, a prospective randomized trial is needed. Nevertheless, stereotactic body radiotherapy remains a suitable option for medically inoperable patients.Published by Elsevier Inc.
