The utilization and impact of the studies published using the National Cancer Database (NCDB) is currently unclear. In this study, we aim to characterize the published studies, and identify relatively unexplored areas for future investigations.
A literature search was performed using PubMed in January 2017 to identify all papers published using NCDB data. Characteristics of the publications were extracted. Citation frequencies were obtained through the Web of Science.
Three hundred 2 articles written by 230 first authors met the inclusion criteria. The number of publications grew exponentially since 2013, with 108 articles published in 2016. Articles were published in 86 journals. The majority of the published papers focused on digestive system cancer, while bone and joints, eye and orbit, myeloma, mesothelioma, and Kaposi Sarcoma were never studied. Thirteen institutions in the United States were associated with more than 5 publications. The papers have been cited for a total of 9858 times since the publication of the first paper in 1992. Frequently appearing keywords congregated into 3 clusters: "demographics," "treatments and survival," and "statistical analysis method." Even though the main focuses of the articles captured a extremely wide range, they can be classified into 2 main categories: survival analysis and characterization. Other focuses include database(s) analysis and/or comparison, and hospital reporting.
The surging interest in the use of NCDB is accompanied by unequal utilization of resources by individuals and institutions. Certain areas were relatively understudied and should be further explored.
目前尚不清楚使用国家癌症数据库（NCDB）发表的研究的利用情况和影响。在本研究中，我们旨在描述已发表研究的特征，并确定未来研究中相对未被探索的领域。
2017年1月使用PubMed进行文献检索，以识别所有使用NCDB数据发表的论文。提取出版物的特征。通过科学网获取引用频率。
230位第一作者撰写的302篇文章符合纳入标准。自2013年以来，出版物数量呈指数增长，2016年发表了108篇文章。文章发表在86种期刊上。大多数已发表的论文集中在消化系统癌症，而骨骼和关节、眼和眼眶、骨髓瘤、间皮瘤和卡波西肉瘤从未被研究过。美国有13个机构发表了5篇以上的论文。自1992年第一篇论文发表以来，这些论文共被引用9858次。频繁出现的关键词聚集成3个簇：“人口统计学”、“治疗与生存”和“统计分析方法”。尽管文章的主要重点范围极广，但可分为2大类：生存分析和特征描述。其他重点包括数据库分析和/或比较以及医院报告。
对使用NCDB的兴趣激增，但个人和机构对资源的利用并不均衡。某些领域的研究相对较少，应进一步探索。
