ObjectiveTreatment modalities in medically compromised patients with early-stage non-small cell lung cancer (NSCLC) are controversial. Stereotactic body radiotherapy (SBRT) or stereotactic ablative radiotherapy has been increasingly recognized as a favorable alternative to surgical resection for early-stage NSCLC. Many retrospective analyses compared the efficacy of stereotactic body radiotherapy (SBRT) with surgery for early-stage non-small cell lung cancer (NSCLC). However, the efficacy between SBRT and surgery regimens for patients with early-stage NSCLC remains unclear. This study aimed to investigate the efficacy between SBRT and surgery.MethodsPublications on comparison SBRT with Surgery in treatment of early stage non-small cell lung cancer (NSCLC) from 2011 to 2017 were collected. Retrospective trials analyzed the summary hazard ratios (HRs) of overall survival (OS), disease-free survival (DFS), local control survival (LC), regional control survival (RC), loco-regional control survival (LRC), and distant control survival (DC) between SBRT and Surgery. The major outcomes measures were hazard ratios (HRs). Meta-analysis Revman 5.3 software was used to analyze the combined Pooled HRs using fixed- or random-effects models according to the heterogeneity.ResultA systematic literature search was conducted including14 studies. In this meta-analysis, patients with SBRT achieved inferior OS, DFS, LC, RC, LRC and DC, compared with surgery.ConclusionIn this study we found more favorable outcomes with stage I NSCLC treated with SBRT. The surgery had no obvious advantages in this meta-analysis. Although surgery has become the recommended treatment at present, SBRT has potential to be an alternative treatment as a novel non-invasive radiation therapy modality in patients with stage I-II NSCLC.
