There is debate regarding the use of stereotactic ablative radiotherapy (SABR) or surgery for patients with early stage non-small cell lung cancer (NSCLC). This meta-analysis compared the clinical efficacy of SABR and lobectomy in stage I NSCLC patients.
An online search identified eight eligible articles (including 2 trials and 7 cohort studies) for inclusion. The odds ratio (OR) was used as a summary statistic. Overall survival (OS), cause-specific survival (CSS), and recurrence-free survival (RFS) were selected to calculate ORs with 95% confidence intervals (CI). Fixed-effects or random-effects models were conducted according to study heterogeneity.
There were no significant differences between SABR and lobectomy in terms of one-year OS or CSS. Significant benefits of surgery were observed in three-year OS (OR 2.11, 95% CI 1.55-2.86), three-year CSS (OR 1.94, 95% CI 1.05-3.57), three-year RFS (OR 1.63, 95% CI 1.12-2.36), and five-year OS (OR 2.40, 95% CI 1.71-3.36). In addition, lobectomy demonstrated a beneficial trend in one-year RFS, five-year RFS, and CSS.
Meta-analyses of current evidence suggested that lobectomy provides better long-term survival outcomes for stage I NSCLC patients.
对于早期非小细胞肺癌(NSCLC)患者,立体定向消融放疗(SABR)或手术的应用存在争议。本荟萃分析比较了SABR与肺叶切除术在I期NSCLC患者中的临床疗效。
通过在线检索确定了8篇符合纳入标准的文章(包括2项试验和7项队列研究)。采用比值比(OR)作为汇总统计量。选择总生存期(OS)、病因特异性生存期(CSS)和无复发生存期(RFS)来计算95%置信区间(CI)的OR值。根据研究异质性采用固定效应或随机效应模型。
SABR与肺叶切除术在1年OS或CSS方面无显著差异。在3年OS(OR 2.11,95%CI 1.55 - 2.86)、3年CSS(OR 1.94,95%CI 1.05 - 3.57)、3年RFS(OR 1.63,95%CI 1.12 - 2.36)和5年OS(OR 2.40,95%CI 1.71 - 3.36)方面观察到手术有显著益处。此外,肺叶切除术在1年RFS、5年RFS和CSS方面显示出有益趋势。
对现有证据的荟萃分析表明,肺叶切除术为I期NSCLC患者提供了更好的长期生存结果。
