ABSTRACT: Background:
The National Comprehensive Cancer Network (NCCN) guidelines did not give an explicit comparison of the efficacy between surgery and radiotherapy in treating Stage-III N2 non–small cell lung cancer (NSCLC) patients, leaving a paucity for clinical reference. Through this study, we try to locate the optimum treatment strategy including surgical type for these patients. Methods:
A systematic literature search was performed from PubMed, Cochrane Library, Embase, and Google Scholars. The endpoints were overall survival (OS), mean OS, and progression-free survival (PFS). The treatments comprised radiotherapy, lobectomy, and pneumonectomy. Network meta-analysis was carried out for calculating the odds ratio (OR) for binary variants. All the analyses implemented Stata 17.0 MP. Results:
Eight clinical trials reporting 1756 patients met the inclusion criteria. Radiotherapy and surgery were equivalent in improving patients’ OS (OR = 0.842, 95% confidence interval [CI]: [0.645, 1.099]). The mean OS of patients were similar in terms of radiotherapy, lobectomy, and pneumonectomy. Besides, radiotherapy and surgery had equivalent effects in improving PFS (OR = 0.896, 95% CI: [0.718, 1.117]). Conclusions:
Since lobectomy and pneumonectomy following neoadjuvant treatments had equivalent efficacy in prolonging OS for patients with stage-IIIA N2 NSCLC compared with definitive radiotherapy, young patients with favorable performance status (0) should try surgery to pursue better prognosis while elderly patients with unfavorable PS or radiosensitive pathology types should accept definitive radiotherapy. More high-quality clinical trials are needed to support our findings.
