基于Web of Science的残胃癌研究可视化及热点分析

Visualization and hotspots analysis of research for gastric stump cancer based on Web of Science

背景与目的:残胃癌是一类具有特殊致病因素、临床特征和预后特点的胃恶性肿瘤,发病率呈逐年上升趋势,但在其发生发展机制和手术治疗等方面仍存在较多争议,且当前尚无针对国际残胃癌领域已有的文献进行归纳和可视化分析的研究。本文运用文献计量学的方法对残胃癌领域的英文文献进行可视化分析,梳理其研究现状和热点问题,探讨研究趋势,为该领域未来的研究提供参考依据。方法:在Web of Science核心合集中检索自建库起至2022年12月31日残胃癌领域的文献,应用Excel、VOSviewer和CiteSpace进行发文整体情况分析、社交网络及时序分析、作者共被引分析、关键词共现网络分析和关键词突现情况分析。结果:共纳入400篇英文文献,其中最早的文献发表于1964年。分析时间段内残胃癌领域英文文献多发表在胃肠病学、肿瘤学及手术学专业期刊,年发文量呈波动性缓慢增长,近3年趋于平稳。被引频次最高的文献为O hashi M(2007年),其次为S asako M(1991年);发文量前三的国家分别为日本(n=127)、中国(n=42)、韩国(n=32);荷兰阿姆斯特丹大学是发文最多的机构(n=10),该机构的Offerhaus GJA在残胃癌领域发文最多(n=10)。共被引频次位列前三的作者分别是Ohashi M(87次)、Sasako M(77次)和Balfour DC(72次)。残胃癌的研究以同一机构内的作者合作为主,除日本国立癌症研究中心同时与国内外的机构均存在密切的合作关系外,国家间、机构间的合作仍相对较少,存在明显的地域性。关键词共现网络显示Surgery(137次)、Distal Gastrectomy(126次)等为该领域的高频关键词。关键词突现情况表明该领域前期主要对良性溃疡性疾病行胃BillrothⅡ式切除术后的残胃癌展开研究;中期主要关注幽门螺杆菌感染对残胃的致癌作用、早期残胃癌的内镜切除,以及残胃癌的外科手术淋巴结清扫;近期研究热点为残胃癌的微创治疗、手术并发症、临床病理特征及生存预后,并有望成为未来的研究趋势。结论:残胃癌英文文献总体数量偏少,VOSviewer和CiteSpace能对残胃癌的研究现状进行系统、直观的分析,我国应加强与日本、荷兰等国家的合作,并紧跟当前残胃癌的研究热点,提高学术影响力。

Background and Aims:Gastric stump cancer is a subtype of malignant gastric tumors characterized by distinct pathogenic factors,clinical features,and prognosis.Its incidence has been on the rise in recent years,yet there remain several controversies regarding its development mechanism and surgical treatment.Furthermore,there has been no comprehensive or visualized analysis of the existing literature in the international field of gastric stump cancer.Therefore,this study was conducted to make a visualized analysis of English literature in the field of gastric stump cancer through bibliometric methods,aiming to summarize its current research status and hotspots,discuss research trends,and provide a reference for future studies in this field.Methods:The literature in the field of gastric stump cancer was searched in the Web of Science Core Collection from the inception of the database to December 31,2022.The analyses of overall publication patterns,social network,temporal features,co-citation of authors,keyword co-occurrence network and keyword burst were performed using Excel,VOSviewer,and CiteSpace.Results:A total of 400 English literature publications were included,with the earliest publication dating back to 1964.Within the analyzed timeframe,English literature on gastric stump cancer was predominantly published in specialized journals related to gastroenterology,oncology,and surgery.The annual publication rate showed slow fluctuations,with a recent stabilization over the past three years.The most frequently cited literature was authored by O hashi M(2007),followed by S asako M(1991).The top three countries in terms of publication output were Japan(n=127),China(n=42),and Republic of Korea(n=32).The University of Amsterdam in the Netherlands was the leading institution in terms of publications(n=10),with Offerhaus GJA being the most prolific author in the field of gastric stump cancer from this institution(n=10).The top three co-cited authors were Ohashi M(87 citations),Sasako M(77 citations),and Balfour DC(72 citations).Collaboration among authors within the same institution was a prevalent trend in gastric stump cancer research,with relatively limited inter-country and interinstitutional collaborations,except the National Cancer Center in Japan which demonstrated close the Netherlands and align its research with the current hotspots in gastric stump cancer,thereby increasing its academic influence in this field.
