. Lung cancer remains the leading cause of death because of cancer globally in the past years. To inspire researchers with new targets and path-breaking directions for lung cancer research, this study is aimed at exploring the research trends and emerging hotspots in the lung cancer surgery literature in the recent decade.. This cross-sectional study combined bibliometric and network analysis techniques to undertake a quantitative analysis of lung cancer surgery literature. Dimensions database was searched using keywords in a 10-year period (2012-2021). Publications were characterized by publication year, research countries, field citation ratio, cooperation status, research area, and emerging hotspots.. Overall, global scholarly outputs of lung cancer surgery had almost doubled during the recent decade, with China, Japan, and the United States leading the way, while Denmark and Belgium predominated in terms of scientific influence. Network analysis showed that international cooperation accounted for a relatively small portion in lung cancer surgery research, and the United States, China, and Europe were the prominent centers of international cooperation network. In the recent decade, research of lung cancer surgery majored in prevention, biomedical imaging, rehabilitation, and genetics, and the emerging research hotspots transformed into immunotherapy. Research on immunotherapy showed a considerable increase in scientific influence in the latest year.. The study findings are expected to provide researchers and policymakers with interesting insights into the changing trends of lung cancer surgery research and further generate evidence to support decision-making in improving prognosis for patients with lung cancer.
在过去几年中，肺癌仍然是全球因癌症导致死亡的主要原因。为了为肺癌研究的研究人员提供新的靶点和开创性的方向，本研究旨在探索近十年肺癌手术文献的研究趋势和新兴热点。本横断面研究结合文献计量学和网络分析技术，对肺癌手术文献进行定量分析。在10年期间（2012 - 2021年）使用关键词在Dimensions数据库中进行检索。出版物的特征包括出版年份、研究国家、领域引用率、合作状态、研究领域和新兴热点。总体而言，近十年全球肺癌手术学术产出几乎翻了一番，中国、日本和美国领先，而丹麦和比利时在科学影响力方面占主导地位。网络分析表明，国际合作在肺癌手术研究中占比相对较小，美国、中国和欧洲是国际合作网络的突出中心。近十年，肺癌手术研究主要集中在预防、生物医学成像、康复和遗传学方面，新兴研究热点转变为免疫疗法。免疫疗法研究在最近一年的科学影响力有显著增加。研究结果有望为研究人员和政策制定者提供有关肺癌手术研究变化趋势的有趣见解，并进一步为改善肺癌患者预后的决策提供支持证据。
