Aim:This study aims to describe the current global research status, identify the most influential countries, research institutions, researchers and research hotspots through conducting bibliometric analysis on literature related to the correlation between gut microbiota and tumor immune microenvironment (TIME) from January 1, 2014, to May 28, 2024, in order to provide insights for future research and development trends. Methods:We searched for all literature related to gut microbiota and TIME published from January 1, 2014, to May 28, 2024, in the Web of Science Core Collection database. Then, we further conducted bibliometric analysis and created visual maps of the published literature on countries, institutions, authors, keywords, references, etc. by using CiteSpace (6.2R6), VOSviewer (1.6.20), and bibliometrics (based on R 4.3.2). Results:491 documents were ultimately included, with a rapid increase in the number of publications starting from 2019. The country with the highest number of publications is China, followed by the United States. And Germany has the highest number of citations of literature. From the centrality perspective, the United States has the highest influence in this field. The institution with the most publications is Shanghai Jiao Tong University in China. However, the institution with the most citations is the NIH National Cancer Institute (NCI) in the United States. As for the author, Professor Giorgio Trinchieri from the National Institutes of Health has produced the most results in this field. And the most citations are FAN XZ. The results of journal publications show that the top three journals with the highest number of published papers are Frontiers in Immunology, Cancers, and Frontiers in Oncology. The top three most frequently occurring keywords are gut microbiota, tumor microenvironment, and immunotherapy. Conclusions: This study systematically elaborates on the research progress related to gut microbiota and TIME over the decade year. Research results indicate that the number of publications has rapidly increased since 2019, with research hotspots including ”gut microbiota”, ”tumor microenvironment” and ”immunotherapy”. Exploring specific gut microbiota or derived metabolites on the behavior of immune cells in the TIME, regulating the secretion of immune molecules, influencing immunotherapy are research hotspots and future research directions.
