目的：本研究旨在可视化和分析放射治疗直肠癌研究热点，并为后续研究提供清晰和可视化的参考。方法：通过 WoSCC（2010年至2019年）对“外部束辐射治疗（EBRT）直肠癌”的文献科学计量分析。数据使用 Microsoft Office Excel（2019年）和 CiteSpace（V.5.7.R1）进行可视化和分析。结果：下载了4,263篇相关文章。每年发表的文章数量逐年增加（2010-2020年）。美国发表的文章数量最多。英国与其他国家/地区的合作最强。莱顿大学发表的文章数量最多，德克萨斯大学 MD 安德森癌症中心与其他学术机构有着广泛的合作。《结肠直肠疾病》发表的文章数量最多，而《临床肿瘤学杂志》被引用最多。27篇文章成为持续至2020年的最强引爆引用。近年来，有很多研究关注“观察等待”，“短程放疗”，“MRI”，“新辅助放疗”，“MRI在直肠癌中的应用”，“化疗方案改进”，“添加辅助化疗”等方面。结论：目前的研究热点可能是“观察等待”，“短程放疗”，“MRI”，“新辅助化疗”，“MRI在直肠癌中的应用”，“化疗方案改进”，以及“添加辅助化疗”。 ©作者。

Purpose: The aim of this study is to visualize and analyze the research hot pots in radiation therapy for rectal cancer and provide researchers with a clear and visual reference for subsequent studies. Methods: The literature scientometric analysis about "external beam radiation therapy (EBRT) for rectal cancer" was made through the WoSCC (2010 to 2019). And the data was visualized and analyzed by the Microsoft Office Excel (2019) and CiteSpace (V. 5.7.R1). Results: 4,263 relevant articles were downloaded. The number of published articles per year has been increasing (2010-2020). The United States published the highest number of articles. The UK has the strongest partnerships with other countries/regions. Leiden University has the highest number of published articles and University Texas MD Anderson Cancer Center has extensive collaborations with other academic institutions. The number of articles published in the Diseases of the Colon Rectum is the most, and the Journal of Clinical Oncology is the most cited. 27 articles became the strongest burst citations lasting until 2020. In recent years, a lot of research has been done on "watch and wait", "short-course radiotherapy", "MRI", "neoadjuvant radiotherapy, "MRI in rectal cancer", "chemotherapy regimen improvement", "adding adjuvant chemotherapy", and so on. Conclusion: The current research hot pots may be the "watch and wait", "short-course radiotherapy", "MRI", "neoadjuvant chemoradiotherapy", "MRI in rectal cancer", "chemotherapy regimen improvement", and "adding adjuvant chemotherapy".© The author(s).
