Abstract
PurposeA population-based matched-pair comparison was performed to compare the efficacy of stereotactic body radiotherapy (SBRT) versus surgery for early-stage non-small cell lung cancer (NSCLC). MethodsAll the eligible studies were searched by PubMed, Medline, Embase, and the Cochrane Library. The meta-analysis was performed to compare odds ratios (OR) for overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), local control (LC), and distant control (DC). ResultsSix studies containing 864 matched patients were included in the meta-analysis. The surgery was associated with a better long-term OS in patients with early-stage NSCLC. The pooled OR and 95% confidence interval (CI) for 1-year, 3-year OS were 1.31 [0.90, 1.91] and 1.82 [1.38, 2.40], respectively. However, the difference in 1-year and 3-year CSS, DFS, LC and DC was not significant. ConclusionsThis systematic review found a superior 3-year OS after surgery compared with SBRT, which supports the need to compare both treatments in large prospective, randomized, controlled clinical trials.
