摘要
目的利用文献计量分析方法,研究2012-2021年发表在PubMed收录期刊上的食管癌相关文献,以了解世界范围食管癌研究现状的分布规律、发展趋势及研究热点,为食管癌研究的开展提供参考。方法从PubMed数据库中(https://pubmed.ncbi.nlm.nih.gov/)下载2012-01-01-2021-12-31相关文献,以医学主题词“Esophageal Neoplasms”(MeSH)为关键词进行检索,检索日期为2022-07-20。采用NoteExpress 2.0与VOSviewer 16.0对检索结果按年份分布、国别分布、语言分布、期刊分布、核心作者、研究热点、基金资助等进行统计分析。结果2012-2021年,PubMed共检索到21544篇文章与食管癌研究有关,文献的年平均增长率为3.34%。其中英文文献数量占比为93.16%,年均增长率为4.08%。有20218篇为期刊文章。中国是世界上食管癌文献产量最高的国家,共7073篇,其次是日本(3123篇)、荷兰(808篇)和德国(762篇)。按国内生产总值(GDP)标准化后,丹麦(14.51/10亿)处于领先地位,而当按人口标准化后,格鲁吉亚的文献产量(1.50/100万)位居首位。这些文章发表在1574种不同的期刊上,前3位发表文章最多的期刊是Dis Esophagus、Ann Surg Oncol和Ann Thorac Surg。其研究热点主要集中在食管切除术、同步放化疗、危险因素、基因表达调控、细胞增殖这5个方面。结论2012-2021年食管癌研究呈上升趋势,且英文文献的占比在逐渐增大。该领域文章主要以英文发表,因此该领域的研究人员应提高英语阅读和写作能力,以跟上最新发展。中国已与日本和荷兰一起成为食管癌研究的领导者。这3个国家应加强合作,共同应对这一领域的诸多挑战。目前食管癌的研究已出现了食管癌切除术、同步放化疗等新热点,研究者们可以选择食管癌的治疗手段这一方向进行深入研究。
Objective To utilize bibliometric analysis methods to investigate esophageal cancer-related literature published in PubMed-indexed journals from 2012 to 2021.The objective is to understand the distribution patterns,trends,and research hotspots in the global landscape of esophageal cancer research.This research aims to provide insights in esophageal cancer research.Methods Literature was downloaded from the PubMed database(https://pubmed.ncbi.nlm.nih.gov/)covering the period from January 1,2012,to December 31,2021.The search was conducted using the Medical Subject Heading(MeSH)term"Esophageal Neoplasms"as the keyword.The search date was July 20,2022.Statistical analysis of the search results,including distribution by year,country,language,journal,core authors,research hotspots,and funding,was performed using NoteExpress 2.0 and VOSviewer 16.0 software.Results Throughout the study period from 2012 to 2021,a total of 21544 articles related to esophageal cancer research were identified.The average annual growth rate of publications was 3.34%.Among these,93.16%were in English,with an average annual growth rate of4.08%.Additionally,20218 of these articles were classified as"journal articles".China had the highest publication output in esophageal cancer research,with 7073 articles,followed by Japan(3123 articles),the Netherlands(808 articles),and Germany(762 articles).When standardized by gross domestic product(GDP),Denmark(14.51/10 billion)led the pack,while when standardized by population,Georgia had the highest publication output(1.50/1 million).These articles were published in 1574 different journals,with the top three journals being Dis Esophagus,Ann Surg Oncol,and Ann Thorac Surg.The research hotspots primarily focused on esophagectomy,concurrent chemoradiotherapy,risk factors,gene expression regulation,and cell proliferation.Conclusions Esophageal cancer research has shown an upward trend from 2012 to 2021,with an increasing proportion of publications in English.Given the predominant use of English in this field,researchers in this area should enhance their English reading and writing skills to stay updated with the latest developments.China,Japan,and the Netherlands have emerged as leaders in esophageal cancer research,and collaboration among these countries is essential to address the challenges in this field.Current research trends in esophageal cancer include esophagectomy,concurrent chemoradiotherapy,and other emerging areas,providing opportunities for in-depth investigations by researchers.
