目的分析2006-2015年国际上鼻咽癌相关研究文献的分布规律和研究热点,旨在为我国鼻咽癌的科学防治提供参考信息。方法利用书目共现分析系统(BICOMB 2013)对2006-2015年美国国立医学图书馆Pubmed数据库收录的鼻咽癌相关研究文献进行文献计量分析,采用SPSS 20.0对词篇矩阵进行系统聚类分析,并根据共现矩阵绘制主题战略坐标图。结果共检索到鼻咽癌科研文献5 403篇,年发文数量呈波动性增长。语种以英语为主,美国发文量最多,我国发文量位居第3。鼻咽癌研究高频主题词57个,聚类分析将高频主题词聚为8类,依次为鼻咽癌的外科手术、遗传学、流行病学、诊断、影像学检查、药物治疗、病理学和放射治疗。结论美英两国是国际鼻咽癌研究领域的主导力量,病理学研究已成为鼻咽癌研究主题的核心,鼻咽癌遗传学研究趋于成熟,适形调强放疗技术已成为鼻咽癌研究的前沿。
Objective To analyze the distribution and research hotspots of international nasopharyngeal cancer related literature from 2006 to 2015, and to provide reference information for the scientific prevention and treatment of nasopharyngeal carcinoma in China. Methods Bibliometrics co-occurrence analysis system (BICOMB 2013) was used to document the literature about nasopharyngeal carcinoma in the Pubmed database of the National Library of Medicine from 2006 to 2015. SPSS 20.0 was used to systematically cluster the essay matrices. According to the co-occurrence matrix mapping thematic strategic coordinates. Results A total of 5 403 nasopharyngeal cancer research papers were retrieved, and the number of papers published increased year by year. Language is mainly in English, with the largest number of documents published in the United States. There were 57 high-frequency keywords in nasopharyngeal cancer research. Clustering analysis clustered the high-frequency keywords into 8 categories, followed by surgery, genetics, epidemiology, diagnosis, imaging examination, drug treatment, Neo-confucianism and radiotherapy. Conclusions The United States and the United Kingdom are the leading forces in the field of international nasopharyngeal carcinoma. Pathological studies have become the core of nasopharyngeal cancer research. The genetic studies of nasopharyngeal carcinoma have become more mature. The frontier.
