基于Web of Science的肺癌可改变危险因素文献计量和可视化分析

目的 旨在探究肺癌发病的可改变危险因素（即在任何方面都可以通过干预而改变的决定因素）的研究现状、热点和前沿。 方法 检索并分析Web of science (WOS) 数据库相关研究文献,利用Excel 2019分析发文量,Citespace 5.6.R1软件构建国家、机构合作网络,关键词共现和突现网络及参考文献的共被引网络及共被引聚类时间轴图。 结果 共获得文献1 186篇,发文量以1980年为界显著增加,共被引居前10的文献涉及7个学科,期刊平均IF2018 = 6.66。发文量居前3的国家和机构分别是美国、法国、中国和美国国家癌症研究所、国际癌症研究中心、法国国家健康与医学研究院。国家间合作链条以美国为中心,中国、加拿大、英国、瑞典、荷兰等国在国家间合作具有较强的中心性。吸烟一直是热点,方法从以病例-对照研究为主演变为以队列研究为主,热门领域从最开始的饮食扩展到职业和空气中有害物质接触。结论 肺癌可改变危险因素研究涉及领域广,研究热点集中于行为习惯和有害暴露,发文质量高,欧美国家和机构发文量及发文时间处领先地位。

Bibliometric and visualized analysis of modifiable risk factors of lung cancer based on Web of Science

To investigate the current research hotspot and frontier of modifiable risk factors for lung cancer. Methods The Web of Science database was searched for relevant research literature, and the number of publications was analyzed using Excel 2019. CiteSpace 5.6.R1 software was used to construct national and institutional cooperation network, keyword co-occurrence and emergence network, co-citation network, and co- citation clustering time axis. Results A total of 1 186 papers were identified, and the number of publications increased significantly after 1980. The top 10 co -cited references covered seven disciplines, with an average IF2018 of 6.66 points. The top three countries and institutions in terms of number of publications were the United States, France, China, and the National Cancer Institute, the International Agency for Research on Cancer, and the French National Institute of Health and Medicine, respectively. The intercountry collaborations were centered on the United States, with China, Canada, the United Kingdom, Sweden, and the Netherlands having a strong centrality in intercountry collaborations. Smoking had been a hotspot topic, with predominant research methods shifted from case -control studies to cohort -based studies, and popular research focuses expanding from diet in the beginning to occupational and airborne hazardous substance exposure. Conclusion The research on modifiable risk factors for lung cancer covers a wide range of fields, focusing on behavioral habits and harmful exposures. The quality of publications is high. Developed countries in Europe and America are leading this field in terms of number and time of publications.
