Objective To analyze the research hotspots and trends of biomarkers for diseases based on genomics and thus provide basis for the future studies in this field. Method Based on the Web of Science,we analyzed the genomics-based biomarkers for diseases in literature published between 2006 and 2018 in terms of country and institutions,knowledge base,research hotspots,and trends by using bibliometric methods and CiteSpace software. Results A total of 998 articles were retrieved.The total number of articles has shown an upward trend and reached a peak of 112 in 2017 and 2018.Most articles(n=477)were from the United States,follwed by China(n=93).Nature,P Natl Acad Sci USA,PLoS One,Science,and New Engl J Med are core journals in this field.Keywords co-occurrence analysis identified four research hotspots:disease research,research method and technology,research level,and application purpose. Conclusion Research in functional genomics,cancer immunotherapy,genome-wide association and multi-omics techniques,personalized medicine,and precision medicine are research hotspots and frontiers in this field.
