This study intends to create a series of scientific maps to quantitatively estimate hot spots and emerging trends in segmentectomy versus lobectomy for non-small cell lung cancer (NSCLC) research with bibliometric methods.
Articles published on segmentectomy versus lobectomy for NSCLC were extracted from the Web of Science Core Collection (WoSCC). Extracted information was analyzed quantitatively using bibliometric analysis by CiteSpace to find hot spots and frontiers in this research area.
A total of 362 scientific articles on segmentectomy versus lobectomy for NSCLC were collected, and the annual publication rate increased over time from 1992 to 2019. The leading country and the leading institution were the United States and University of Pittsburgh, respectively. Furthermore, the most prolific researchers were, namely, James D. Luketich, Rodney J. Landreneau, Matthew J. Schuchert, Morihito Okada, and David O. Wilson. The analysis of keywords pointed out that carcinoma, bronchogenic carcinoma, limited resection, segmental resection, and morbidity are hot spots and lymph node dissection, minimally invasive surgery, impact, epidemiology, and high risk are research frontiers in this field.
Publications related to segmentectomy versus lobectomy for NSCLC have made great achievements based on bibliometric analysis in recent years. However, further research and global collaboration are still required. Finally, we find that segmentectomy for the treatment of NSCLC is receiving much more attention from researchers globally compared with lobectomy in this research area.
本研究旨在运用文献计量学方法创建一系列科学图谱，定量评估非小细胞肺癌（NSCLC）楔形切除术与肺叶切除术的研究热点和新兴趋势。
从科睿唯安 Web of Science 核心合集（WoSCC）中提取关于 NSCLC 楔形切除术与肺叶切除术的文章。使用 CiteSpace 对提取的信息进行定量分析，以找到该研究领域的热点和前沿。
共收集了 362 篇关于 NSCLC 楔形切除术与肺叶切除术的科学文章，1992 年至 2019 年，年发表率呈上升趋势。主要国家和机构分别是美国和匹兹堡大学。此外，最具影响力的研究人员是 James D. Luketich、Rodney J. Landreneau、Matthew J. Schuchert、Morihito Okada 和 David O. Wilson。关键词分析指出，肺癌、支气管源性癌、局限性切除术、节段切除术和发病率是该领域的热点，淋巴结清扫术、微创手术、影响、流行病学和高危因素是研究前沿。
基于近年来的文献计量学分析，非小细胞肺癌楔形切除术与肺叶切除术相关研究取得了巨大成就，但仍需进一步研究和全球合作。最后，我们发现与肺叶切除术相比，全球研究人员对 NSCLC 楔形切除术的关注度更高。
