title: Trends of triple negative breast cancer research (2007-2015): A bibliometric study.
abstract: BACKGROUND
  Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype. However, there have been limited data to evaluate the trend of TNBC research. This study aims to investigate the trend of TNBC research and compare the contribution of research from different regions, organizations, and authors.
  
  
  METHODS
  TNBC-related publications from 2007 to 2015 were retrieved from the Web of Science database. Excel 2013 (Redmond, Washington, USA), GraphPad Prism 5 (GraphPad Prism Software Inc., San Diego, CA), and VOSviewer (Leiden University, Leiden, Netherlands) software were used to analyze the trend of TNBC research. This article does not contain any studies with human participants or animals performed by any of the authors.
  
  
  RESULTS
  A total of 1695 papers were identified and were cited 34,078 times with a time limit of May 27, 2016. The United States accounted for 43.10% of the articles, 57.59% of the citations, and the highest H-index (64). China ranked second in total number of articles, but seventh in citation frequency (1998) and ninth in H-index (21). The journal Breast Cancer Research and Treatment had the highest number of publications. The author, Narod SA, has published the most papers in this field (30). The keyword "receptor" was mentioned the most, 1489 times, and the word "myeloid cell leukemia-1 (MCL-1)" was the latest hot spot by 2015.
  
  
  CONCLUSIONS
  Literature growth related to TNBC is expanding rapidly in recent years. The quality of the articles from China still requires improvement. Newest progress of the TNBC research may be released by the journal Breast Cancer Research and Treatment first. Narod SA, Gonzalez-Angulo AM, and Hortobagyi GN may be good candidates for collaborative research in this field. MCL-1 is an emerging topic that should be closely observed.
