摘要
目的:通过文献计量学方法,系统分析食管癌营养领域的研究现状、热点及前沿趋势,为该领域的后续研究提供参考依据。方法:检索Web of Science核心合集数据库建库至2025年关于食管癌营养的相关文献,采用Excel 2019、CiteSpace、VOSviewer及R软件“Bibliometrix”包进行文献计量分析。通过关键词共现、聚类及突现分析,绘制可视化知识图谱,以揭示该领域的研究动态。结果:共纳入787篇文献,整体发文量在1978—2024年呈上升趋势。中国在发文量上位居首位,同时中国与美国在该领域的合作最为密切。美国国立癌症研究所和中国医学科学院在发文量及被引频次方面表现突出,William J.Blot是该领域最具影响力的学者之一,而《Diseases of the Esophagus》期刊发文量最高。关键词分析共识别出16个主要聚类,涵盖体重管理、营养干预、应激反应等多个方面。突现分析显示,“肌少症”“营养不良”和“生活质量”为当前研究的前沿热点。结论:可视化分析结果全面展示了食管癌营养领域的研究现状、热点及前沿趋势,为未来研究提供了重要的参考依据。该领域正处于快速发展阶段,未来研究可进一步聚焦于精准化干预策略的探索与实践。
Objective:This study aims to systematically analyze the research status,hotspots,and frontier trends in the field of nutrition in esophageal cancer through bibliometric methods,providing a reference for future research in this area.Methods:Relevant literature on nutrition in esophageal cancer from the inception of the Web of Science Core Collection database up to 2025 was retrieved.Bibliometric analysis was conducted using Excel 2019,CiteSpace,VOSviewer,and the“Bibliometrix”R package(R-Studio).Co-occurrence,clustering,and burst analysis of keywords were performed to construct visual knowledge maps,revealing the research dynamics in this field.Results:A total of 787 articles were included,with the overall publication volume showing an upward trend from 1978 to 2024.China ranked first in terms of publication volume,while cooperation between China and the United States was the most frequent in this field.The National Cancer Institute of the United States and the Chinese Academy of Medical Sciences demonstrated outstanding performance in both publication output and citation frequency.William J.Blot was identified as one of the most influential scholars in this field,and publications related to《Diseases of the Esophagus》had the highest publication volume.Keyword analysis identified 16 main clusters,covering weight management,nutritional intervention,stress response,and other aspects.Burst analysis revealed“sarcopenia”“malnutrition”and“quality of life”as current research frontiers and hotspots.Conclusion:The visualization analysis comprehensively presents the research status,hotspots,and frontier trends in the field of nutrition for esophageal cancer,providing an important reference for future research.This field is currently in a stage of rapid development,and future studies could further focus on the exploration and implementation of precise intervention strategies.
