基于CiteSpace的中美肺癌筛查研究现状及热点分析

Current status and hotspot analysis of CiteSpace-based lung cancer screening research in China and the United States

目的 比较中美肺癌筛查的现状及趋势,以期为我国肺癌筛查领域的研究发展提供科学依据与参考。方法 对中国知网(CNKI)和Web of Science核心合集数据库的文献进行主题词检索,并采用文献计量软件CiteSpace 5.8.R3对1979-2022年发表的中美相关文献进行可视化分析,以掌握中美两国关于该领域的研究现状、热点及前沿。结果 研究发现,中美关于肺癌筛查的相关研究总体发文量较低(1 093篇)且正式起步较晚约为21世纪初。中美按照发文量变化经历了萌芽探索期(分别为1979-2012和2000-2002年)和快速上涨期(分别为2013-2022和2003-2022年)。国内相关领域作者与机构合作相对分散;中美肺癌筛查领域研究重点有所相同但各有侧重,2国研究都关注肺结节、高危人群和风险预测等,但国内集中于筛查效果评价与筛查方法的研究,而美国更关注筛查的成本效益和实现规范化的筛查诊治流程。未来一段时期国内肺癌筛查的发展前沿将集中于人工智能、危险因素、减少假阳性等方面的研究,而美国相关研究则可能围绕肺癌筛查实施及阻碍、影响等方面展开。结论 目前关于肺癌筛查领域的研究仍然存在巨大发展空间与潜力,尤其国内该领域研究需要针对相关不足进一步发展完善。

Objective To compare the current status and trends of lung cancer screening in China and the United States, and to provide a scientific basis and reference for the research development in the field of lung cancer screening in China.Methods This study conducted a subject term search of the literature in China National Knowledge Infrastructure(CNKI) and core collection in Web of Science database(WOS),and used the bibliometric software CiteSpace 5.8.R3 to visualize and analyze the relevant literature published in China and the United States from 1979 to 2022,in order to grasp the current status, hot spots and frontiers of research on this field in China and the United States.Results The study found that the overall volume of research on lng cancer crening in China and the Unnited States was low(1 093 articles)and started formally late, with a formal start around the beginning of the 21st century.According to the changes in the number of articles published, China and the United States experienced a period of budding exploration and a period of rapid rise, with the budding exploration period from 1979 to 2012 and 2000 to 2002,respectively, and the rapid rise period from 2013 to 2022 and 2003 to 2022,respectively.In China, authors and institutions in related fields were relatively fragmented;the research focus of lung cancer screening in China and the Unitedd States in the same but each had its own emphasis.Both countries focused on lung nodules,high-risk groups,and risk prediction,but China focused on the evaluation of screening effects and screening methods,while the Unitedd States focused more on the cost-effectiveness of screening and achieving a standardized screening and treatment process.The frontiers of lung cancer screening development in China in the coming period will focus on artificial intelligence,risk factors,reduction of false positives,ect.While related research in the US was likely to focus on lung acncer screening implementation and impediments,impact,ect.Conclusion There is still great room for development and potential for research in the field of lung cancer screening,especially in China,which needs to be further developed and improved to address the relevant shortcomings.
