OBJECTIVES: Guideline-specified curative therapies for a clinical stage I non-small cell lung cancer (NSCLC) are either lobectomy or Stereotactic Ablative Radiotherapy (SABR). As outcomes of prospective randomized clinical trials comparing these modalities are unavailable, we performed a propensity-score matched analysis to create two similar groups in order to compare clinical outcomes. METHODS: We selected 577 patients, 96 VATS or open lobectomy were treated at Erasmus University Medical Center Rotterdam and 481 SABR patients were treated at VU University Medical Center Amsterdam with clinical stage I NSCLC. RESULTS: Matching of patients according to propensity score resulted in a cohort that consisted of 73 patients in the surgery group and of 73 patients in the SABR group. Median follow-up in the surgery and SABR group was 49 months and 28 months, respectively. Overall survival of patients who underwent surgery was 95% and 80% at 12 and 60 months, respectively. For the SABR group this was 94% at 12 months and 53% at 60 months. No statistical significant difference (p=0.089) in survival was found between these groups. CONCLUSIONS: In this study we found no significant differences in overall survival in propensity matched patients diagnosed with stage I NSCLC treated either surgically or with SABR. After 3 years there seems to be a trend toward improved survival in patients who were treated surgically.
