基于CiteSpace的中国肺癌筛查现状及趋势分析

Current Status and Trends of Lung Cancer Screening in China Based on CiteSpace

目的:肺癌是影响人类生命健康的主要恶性肿瘤之一,其发病隐匿,临床就诊时常已进展至中晚期,预后较差,通过筛查实现肺癌早诊早治是当今肺癌防控工作的重要手段。方法:本文使用文献可视化分析软件CiteSpace对1989~2020年CSSCI、核心期刊、CSCD数据库中收录的肺癌筛查相关文献进行分析,梳理我国肺癌筛查研究领域的发展历程和研究现状。结果:研究结果发现肺癌筛查按照发文量变化经历了起步、发展、快速发展3个阶段;作者合作网络显示未形成较为明显的核心作者群;机构合作网络显示形成了以部分机构为主体的合作集群,但机构间的力量仍较为分散;关键词共现分析发现,“低剂量螺旋CT”、“筛查”、“体层摄影术”等关键词出现频次及中介中心性较高;关键词聚类分析发现,研究热点主题主要集中在肺癌筛查的必要性和可行性,以及肺癌筛查的工具选择及优化。结论:未来应加强跨机构、作者群间的交流合作,促进肺癌筛查领域的均衡发展。

Objective: Lung cancer is one of the most common malignant tumors threatening human life and health. Hidden onset delays optimal diagnosis opportunities until the disease progresses to advanced stages, thus the prognosis is poor. Early diagnosis and treatment through screening is important in current prevention and control of lung cancer. Methods: CiteSpace was used to visualize and analyse articles on lung cancer screening in CSSCI, core journals and CSCD database from 1989 to 2020 and sort out the progress and research status of lung cancer screening in China. Results: Lung cancer screening had experienced beginning, developed and rapidly developed stages according to the number of published papers;core author group could not be extracted from current author information;studied affiliations clustered, to some extent, together in certain small groups, most of the affiliations, however, were still relatively scattered;keywords such as ‘low-dose spiral CT’, ‘screening’, ‘tomography’ were in high centrality and frequency;cluster analysis found that the hot topics mainly focused on the necessity and feasibility of lung cancer screening, as well as the selection and optimization of lung cancer screening tools. Conclusion: In the future, we should strengthen the communication and cooperation between different affiliations and author groups to promote a balanced development of lung cancer screening.
