To evaluate the scientometrics characteristics of the scientific production on the treatment of brain tumors with gamma knife radiosurgery in Scopus.
The Scopus database (Elsevier) was used to collect all relevant studies for this bibliometric analysis. Data was obtained as a .csv file; it was downloaded from Scopus and was exported by SciVal to Microsoft Excel for a presentation using tables for more detailed analysis. The citations and the number of papers for the most productive institutions, authors, countries, and journals publishing scientific papers were analyzed on the use of gamma knife radiosurgery for brain tumors.
458 metadata were obtained from scientific publications, on which inclusion and exclusion criteria were applied, leaving 248 studies. The maximum peak of publications was 2018 with 31 publications, and the minimum peak was 2015 with 18. The most related subtopics were neurology, surgery, and oncology, and most of the retrieved papers had only institutional collaboration. As for more productive journals, is first with 23 publications; within the countries with the most scientific publications, we have the United States, Japan, and China. With the United States being the country with the highest number of productions, University of Texas MD Anderson Cancer Center was the main university with the highest scientific production and Sheehan and Trifiletti and American authors dominate the list with the highest number of documents.
Scientific production regarding gamma knife surgery and brain tumors has been increasing during the last 10 years, with a high incidence during 2018, and the highest number of published articles was in the first quartile. Likewise, the United States is the country with the most publications, authors, and universities on the subject. Greater efforts are still lacking from all countries in the world to reach the quantity and quality of production of the United States.
评估Scopus数据库中关于伽玛刀放射外科治疗脑肿瘤的科研产出的科学计量学特征。
使用Scopus数据库（爱思唯尔）收集本次文献计量分析的所有相关研究。数据以.csv文件形式获取；从Scopus下载并由SciVal导出到Microsoft Excel，以便使用表格进行展示以进行更详细的分析。分析了使用伽玛刀放射外科治疗脑肿瘤的科研论文发表数量最多的机构、作者、国家和期刊的引用情况及论文数量。
从科学出版物中获取了458条元数据，应用纳入和排除标准后，剩余248项研究。出版物数量的最高峰是2018年，有31篇出版物，最低峰是2015年，有18篇。最相关的子主题是神经学、外科学和肿瘤学，检索到的大多数论文只有机构合作。在发表论文较多的期刊中，《》以23篇出版物位居第一；在科学出版物数量最多的国家中，有美国、日本和中国。美国是产出数量最多的国家，德克萨斯大学MD安德森癌症中心是科研产出最高的主要大学，希恩、特里菲利蒂和美国作者在文献数量最多的榜单中占主导地位。
在过去10年中，关于伽玛刀手术和脑肿瘤的科研产出一直在增加，2018年发病率较高，发表文章数量最多的处于第一四分位数。同样，美国是该主题出版物、作者和大学数量最多的国家。世界各国仍需做出更大努力，以达到美国的产出数量和质量。
