早期食管癌治疗研究热点及演进趋势:基于CiteSpace的可视化分析

Hotspots and trends of research on early esophageal cancer treatment:visual analysis based on CiteSpace

目的分析早期食管癌治疗的研究现状及趋势,为推动早期食管癌治疗的前沿研究提供指导。方法本研究采用文献计量分析法,筛选2013年1月1日至2023年12月31日期间中国知网(Chinese National Knowledge Infrastucture,CNKI)、中国生物医学文献数据库(China Bilolgy Medicine,CBM)、Web of Science以及PubMed数据库收录的相关文献。采用CiteSpace 6.3.R1软件对纳入文献的年发文量、作者及关键词进行可视化分析。结果共纳入中文文献1752篇,英文文献997篇。2013—2021年,早期食管癌治疗的中文文献发文量一直保持在100篇/年以上,并且高于英文文献。相比之下,英文发文量排名前5的作者发文量(均≥35篇)较中文发文量排名前5的作者(均≥5篇)高,且作者间合作紧密度较高。研究热点和合作状况分析显示,北京协和医学院、中国人民解放军总医院等机构对该领域研究贡献较大,但各研究团队间联系疏松,而国外作者合作较为紧密。关键词分析显示,“内镜”“疗效”“癌前病变”等是中文文献中的高频词。在英文文献中“Therapy”“Mucosal resection”和“Endoscopic mucosal resection”是出现频次较高的关键词。突变分析显示,国内外研究逐渐关注治疗的质量控制及安全性。结论早期食管癌治疗是国内外研究的一个热门领域,研究者间需加强合作。早期食管癌治疗未来研究的热点可能是治疗方法、治疗的并发症与复发状况及其危险因素。

Objective To analyze the research status and trends of early esophageal cancer treatment,and to provide guidance for promoting cutting-edge research on early esophageal cancer treatment.Methods Bibliometric analysis was used to screen the relevant literatures included in the Chinese National Knowledge Infrastucture(CNKI),China Biology Medicine(CBM),Web of Science core database and PubMed database from January 1,2013,to December 31,2023.CiteSpace 6.3.R1 software was used to visually analyze the annual the top five authors in English(all≥35 articles)was higher than that of the top five authors in Chinese(all≥5 articles),with a higher degree of collaboration among authors.The analysis of research hotspots and collaboration status indicated that institutions such as Peking Union Medical College and the Chinese People's General Hospital had made significant contributions to the research in this field.However,the connection among research teams in China were relatively weak,while foreign authors demonstrated closer collaboration.Keyword analysis revealed that frequently used words such as"Endoscopic","Efficacy"and"Precancerous lesion"were prevalent in Chinese literature.In English literature,keywords like"Therapy","Mucosal resection"and"Endoscopic mucosal resection"were morefrequently mentioned.Furthermore,mutation analysis indicated a growing focus on the quality control and safety in treatment both domestically and internationally.Conclusions The treatment of early esophageal cancer is a prominent area of research both domestically and interna-tionally,and researchers should strengthen cooperation.Future research of the treatment of early esophageal cancer may be focused on treatment methods,complications associated with treatment,recurrence rates,and risk factors.
