食管癌手术相关研究现状及趋势的文献可视化分析

Bibliometrics and visualization analysis of esophageal cancer surgery-related researches

目的根据文献计量学方法探索食管癌手术相关研究现况,分析食管癌手术研究的演变规律,寻找中英文文献中关于食管癌手术研究的趋势及热点方向。方法检索Web of Science及中国知网(CNKI)建库至2022年4月1日已发表的食管癌手术相关中英文文献。采用VOSviewer 1.6.18以及CiteSpace 6.1软件对作者、机构及关键词进行聚类,通过社会网络和时序分析,应用Excel、GraphPad及R 4.0.3对食管癌手术领域文献进行可视化研究。结果最终纳入19566篇英文文献及19872篇中文文献,结果提示中英文文献发文量均逐年递增,其中英文文献增幅较快,中文文献2011—2019年年均发文量维持在约1000篇。国家及地区层面:食管癌手术研究主要集中于欧美、日韩及我国,而我国食管癌手术相关研究缺乏与其它国家的合作,较日韩等东亚国家起步晚且影响力较小。关键词分析发现食管癌手术研究既往主要围绕手术方式、并发症及围手术期综合治疗,无论中文还是英文文献均提示近年微创治疗、综合治疗及临床试验等关键词数量显著增加,表明这些方面可能是未来研究的方向和研究趋势。结论目前食管癌手术国内研究较日韩等东亚国家相对不足,研究方向和领域与欧美等发达国家相似,未来食管癌手术相关的微创治疗、综合治疗及临床试验相关内容将可能是热点方向。

Objective To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots.Methods The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1,2022.VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors,institutions,and keywords.For social network and time series analysis,Excel,GraphPad,and R 4.0.3 were used to visualize the literature on esophageal cancer surgery.Results Finally,19566 English literature and 19872 Chinese literature was included.The results demonstrated that the annual publishing of both Chinese and English literature increased over time,with English literature increasing rapidly and Chinese literature maintaining an average number of above 1000 per year from 2011 to 2019.Researches were predominantly centered in Europe,the United States,Japan,South Korea,and China.China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration,which began later than East Asian countries such as Japan and South Korea and had less influence.From the keyword perspective,previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques,complications,and comprehensive perioperative therapy.Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery,comprehensive treatment,and clinical trials increased dramatically during the recent years,indicating that these fields may represent the future directions and research trends.Conclusion Compared to East Asia countries,such as Japan and South Korea,Chinese esophageal cancer surgery-related researches are relatively lacking.The research direction and field are similar to those in developed countries such as the United States and Europe.Future attention may be focused on minimally invasive treatment,comprehensive treatment,and clinical trials associated with surgical treatment of esophageal cancer.
