中国肝癌相关队列研究的文献计量分析

目的回顾分析27年来肝癌领域队列研究的应用趋势,展望未来发展方向。方法检索汇总1991年以来中国大陆地区发表的中英文肝癌队列研究文献,对发表时间、科研单位、研究目标与随访调查情况进行统计分析。结果27年来肝癌相关队列研究论文数量明显增长,英文核心期刊群已形成。中英文论文发表数量年平均增长率分别为20.4%与35.2%,52.3%的中文论文与73.5%的英文论文为近5年内发表。49.2%的中文论文发表在核心期刊,47.3%的英文论文发表在影响因子>3分的期刊。国内期刊发表的研究以病因研究为主(41.5%),多为大样本研究;SCI论文研究主要着眼于肝癌预后研究(40.7%),生存分析运用普遍。结论队列研究在我国肝癌研究领域的应用逐渐增多,其中大样本研究与预后分析较为普遍。虽然队列研究的应用得到重视和推广,但仍需进一步提高研究者对于队列研究的认识,提高随访效果、降低失访率,增加生存分析等科学评估手段的应用,更科学地运用队列研究解决临床问题。

A bibliometric analysis on cohort study of liver cancer in China

Objective To retrospectively analyze the application trend of cohort study in the field of liver cancer in past 27 years and to look forward to the future development trend. Methods Chinese and English papers reporting the cohort studies of liver cancer conducted in the mainland of China since 1991 were included. The literature management software was used to analyze the publication time, institution, type and objective of the studies and the follow-up performance. Statistical analysis was carried out by using SPSS 21.0. Results The number and quality of the papers reporting liver cancer-related cohort studies increased significantly in past 27 years and a core English journal group of this field has formed. The average annual growth rates of Chinese and English papers published were 20.4% and 35.2% respectively. About 52.3% of the Chinese papers and 73.5% of the English papers were published in past five years and the quality of these papers was high. The Chinese papers published on Chinese core journals accounted for 49.2%, and the English papers published on SCI periodicals (IF>3) accounted for 47.3%. For the study objective, those published on the domestic journals mainly focused on the pathogenesis of hepatoma (41.5%), studies with large sample size was the common form. The SCI studies mainly focused on the prognosis of liver cancer (40.7%). High-quality SCI papers are more interested in the studies of prognosis, and survival analysis was the common form. Conclusions The application of cohort study in the field of liver cancer gradually increased in China. Large-scale study and prognosis analysis were conducted commonly. However, it is necessary to further improve the researchers'' understanding of cohort study, improve the follow-up quality, and increase the application of scientific evaluation methods, such as survival analysis, for the better solving of clinical problems.
