Background:
Stage I non-small-cell lung cancer (NSCLC) can be treated by both ablation and sublobar resection (SR). This meta-analysis was therefore designed to better compare the relative safety and efficacy of these two approaches to treating stage I NSCLC.
Materials And Methods:
Relevant studies published through November 2020 in the Cochrane Library, Embase, and PubMed databases were identified for analyses which were conducted with RevMan v5.3.
Results:
In total, 816 potentially relevant articles were identified, of which 8 were ultimately included in the final meta-analysis. Patients in the SR group exhibited a signficantly lower pooled local recurrence (LR) rate (5.0% vs. 25.4%, P < 0.0001), although pooled distant recurrence (DR) rates were similar in both groups (25.7% vs. 23.1%, P = 0.75). The pooled hazard ratio (HR) for overall survival (OS) (HR: 1.23; 95% CI: 1.13-1.33, P < 0.00001), progression-free survival (PFS) (HR: 1.34; 95% CI: 1.15-1.55, P = 0.0002), and cancer-specific survival (HR: 1.39; 95% CI: 1.15-1.70, P = 0.0009) all indicated better survival outcomes among patients that underwent HR treatment, while pooled complication rates were similar in both groups (27.7% vs. 43.8%, P = 0.27). Patients that underwent ablation exhibited significantly shorter pooled post-operative hospitalization relative to those in the SR group (MD: 5.93; 95% CI: 0.78-11.07, P = 0.02). No evidence of publication bias was detected through funnel plot analyses.
Conclusions:
SR treatment of stage I NSCLC patients was associated with a lower LR rate and longer survival as compared to ablation.
