国内外乳房重建研究的现状和重点:一项文献计量学研究

Current status and focus of breast reconstruction research in China and abroad:a bibliometric study

背景与目的:国际癌症研究机构(International Agency for Research on Cancer,IARC)2020年全球癌症负担数据显示,乳腺癌已取代肺癌成为全球第一大癌症。本研究旨在对近5年国内外乳房重建相关研究进行文献计量及可视化分析,了解该领域的研究现状与发展趋势,探讨不同国家、不同学科研究的侧重点,为其他研究者提供参考。方法:分析Web of Science核心合集中近5年乳房重建研究文献的相关信息,利用VOSviewer1.6.15软件对纳入研究的作者、国家、机构和关键词进行提取和可视化分析。结果:共纳入4 815篇符合要求的文献,近5年发文量呈上升趋势。838篇文献(17.40%)由乳腺外科、肿瘤外科发表,3 308篇文献(68.70%)由整形外科发表,669篇文献(13.90%)由两类研究者合作发表。国内外主要作者所在学科存在差异,国外以整形外科作者为主(74.74%);国内则是乳腺外科、肿瘤外科占比更高(138篇,44.52%),而整形外科作者(129篇,41.61%)及两类作者合作发文(43篇,13.87%)占比相对较少。国外主要作者形成的合作发文团体更多,达155个,且团队间联合发文更频繁;国内合作团队16个。乳腺外科研究者对于乳房重建中的肿瘤学相关问题更为侧重,而整形外科研究者则更重视自体组织重建相关研究。结论:乳房重建领域逐渐受到国内外研究者重视。与国外相比,国内乳房重建领域存在高质量研究缺乏、合作研究较少等问题。国内外乳房重建领域研究关注点存在差异,主要与研究者所属专业差异有关。

Background and purpose:According to the 2020 global cancer burden data of the International Agency for Research on Cancer(IARC),breast cancer has replaced lung cancer as the most common type of cancer worldwide.The aim of this study was to conduct a bibliometric and visual analysis of breast reconstruction related research in China and abroad published in the past 5 years,to understand the research status and development trend in this field,to discuss the focus of research in different countries and different disciplines,and to provide reference for other researchers.Methods:Relevant literatures about breast reconstruction were retrieved from the Web of Science Core Collection.The VOS viewer 1.6.15 software was used to extract the authors,countries,institutions and keywords to generate network maps of high-yield authors,institutions and high-frequency keywords clustering network.Results:A total of 4815 documents meeting the requirements were retrieved,which showed an upward trend in the past five years.Regarding the discipline,838 documents(17.40%)were published by breast surgery and Cancer Surgery,3308(68.70%)were published by plastic surgery,and 669(13.90%)were jointly published by both types of researchers.There were differences in the disciplines of the main authors between China and abroad.In China,authors from breast surgery published a larger proportion of documents(138,44.52%),while the number of documents published by authors of plastic surgery(129,44.52%)and the joint publication of both types of authors(43,13.87%)was relatively small.However,foreign documents mainly came from authors of plastic surgery(74.74%).There were more cooperative groups(155)formed by major foreign authors,and more frequent joint publishing between groups,while Chinese authors formed only 16 cooperative groups with less cooperation.Authors from breast surgery focused more on oncology-related issues in breast reconstruction,while in plastic surgery,more attentions were paid on autologous tissue reconstruction.Conclusion:Breast reconstruction has gradually attracted the attention of Chinese and foreign researchers.Compared with foreign countries,there were problems such as lack of high-quality research and less cooperative research in China.There were differences in the research focus of breast reconstruction between China and abroad,which was mainly related to the differences in the disciplines of researchers.
