INTRODUCTION: The use of stereotactic ablative radiotherapy (SABR) over conventional fractionated radiotherapy (CFRT) for early-stage non-small-cell lung cancer (NSCLC) has been advocated, but is also debated in the literature.
METHODS: In this retrospective cohort study, we adopted a target trial emulation framework to identify eligible patients diagnosed between 2011 and 2021 using the Taiwan Cancer Registry. In the primary analysis, the overall survival (OS) was the primary endpoint, whereas incidences of lung cancer mortality and radiation pulmonary toxicity were the secondary endpoints. Extensive supplementary analyses were also conducted.
RESULTS: We included 351 patients in the primary analysis and found that the OS was not significantly different between the SABR (n = 290) and CFRT (n = 61) groups. The propensity score weighting adjusted hazard ratio of death was 0.75 (95% confidence interval 0.53-1.07, p = 0.118). The secondary endpoints and supplementary analyses showed no significant differences.
CONCLUSIONS: The OS of patients with early-stage NSCLC treated with SABR was not significantly different from that of patients treated with CFRT alone. The results of the relevant ongoing clinical trials are eagerly awaited.
