Background: The gold standard surgical therapy for patients with clinical stage I non-small-cell lung cancer (NSCLC) is lobectomy with mediastinal lymph node dissection. While, segmentectomy has emerged as an alternative choice with the advantage of fewer postoperative complications. However, the acceptance of this procedure still remains controversial, and conflicting results exist in the retrospective trials.Objectives: The aim of this meta-analysis was to analysis the survival outcomes of lobectomy in comparison with segmentectomy in treatment of clinical stage I non-small-cell lung cancer. Methods: Computerized literature search was done on the published trials in Pubmed, Embase, Cochrane library databases to June, 2019 to identify clinical trials. Lung cancer-specific survival (LCSS) and overall survival (OS) were measured as outcomes. Statistical analysis was performed using the Meta-analysis Revman 5.3 software.Results: A systematic literature search was conducted including 7 studies. In this meta-analysis, results indicate that lobectomy confers an equivalent survival outcome compared with segmentectomy. Conclusion: No significant differences were found in survival outcomes between lobectomy and segmentectomy. Further prospective large-scale, prospective, randomized trials are needed to explore the reasonable surgical treatment for early resectable lung cancer.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
