Approximately 1,000,000 cases and 769,000 deaths from gastric cancer (GC) occurred in 2020, making it the fourth most prevalent reason for cancer-related fatalities. The objective of this study was to examine the use of radiation therapy (RT) and chemoradiotherapy (CRT) in GC using a quantitative and scientometric method.
A comprehensive search was conducted in the Scopus database for articles on RT and CRT in GC from 2014 to 2023. We utilized the VOSviewer tool for a scientometric analysis covering various aspects such as countries, institutions, authors, journals, references, and keywords.
The study incorporated 15,036 articles related to the subject. China emerged as the top contributor, with the United States and Japan following. A significant positive correlation was found between the article output of countries on RT and CRT in GC and gross domestic product (GDP) and total wealth index, with correlation coefficients of 0.749 and 0.6921, respectively ( < 0.001). The forefront of institutional contribution was marked by the University of Texas MD Anderson Cancer Center. J.A. Ajani from the USA stands out as the most prolific author in this field, having published 112 articles. The leading journal was , and the most cited article in this domain was authored by Smyth, E.C., in 2020, in . Author keywords revealed 6 clusters, with "Esophageal cancer" (655 mentions) and "Gastric cancer" (379 mentions) being the most prevalent.
This pioneering scientometric study provides a comprehensive overview of the current state of research on RT and CRT about GC, evaluating the scholarly output in this field over the past decade. It can be concluded that this research topic has gained significant attention since 2016. While international collaborations are taking place worldwide, there is a need for more support and the expansion of research on RT and CRT in GC, especially in less developed countries. This study provides support to healthcare practitioners, researchers, and surgical aides regarding the global outcomes of RT and CRT in GC investigations.
2020年，全球约有100万例胃癌病例，76.9万人死于胃癌，使其成为癌症相关死亡的第四大常见原因。本研究的目的是采用定量和科学计量学方法，研究胃癌放疗（RT）和放化疗（CRT）的应用情况。
在Scopus数据库中全面检索2014年至2023年关于胃癌RT和CRT的文章。我们使用VOSviewer工具进行科学计量分析，涵盖国家、机构、作者、期刊、参考文献和关键词等各个方面。
该研究纳入了15036篇与该主题相关的文章。中国是最大的贡献国，美国和日本紧随其后。各国关于胃癌RT和CRT的文章产出与国内生产总值（GDP）和总财富指数之间存在显著正相关，相关系数分别为0.749和0.6921（P<0.001）。机构贡献方面，德克萨斯大学MD安德森癌症中心处于前沿地位。美国的J.A. Ajani是该领域最多产的作者，发表了112篇文章。领先的期刊是《 》，该领域被引用最多的文章是Smyth, E.C.于2020年发表在《 》上的。作者关键词显示有6个聚类，其中“食管癌”（提及655次）和“胃癌”（提及379次）最为常见。
这项开创性的科学计量学研究全面概述了胃癌RT和CRT的当前研究状况，评估了过去十年该领域的学术产出。可以得出结论，自2016年以来，这个研究主题受到了极大关注。虽然全球范围内都在进行国际合作，但仍需要更多支持并扩大胃癌RT和CRT的研究，特别是在欠发达国家。本研究为医疗从业者、研究人员和外科助手提供了有关胃癌研究中RT和CRT全球结果的支持。
