Background: The incidence and mortality of tongue squamous cell carcinoma (TSCC) have steadily increased over the past few decades, while survival rates have not significantly improved. This has led to numerous studies and publications. However, to date, no systematic bibliometric analysis or visualization of these publications has been conducted.
Objective: This study aims to provide a clear and intuitive overview of the current knowledge structure and potential future research trends in TSCC through bibliometric and visual analysis of relevant publications.
Methods: Bibliographic data from TSCC-related publications between 2001 and 2021 were extracted from the Web of Science Core Collection. The data were visualized and analyzed using Microsoft Excel, VOSviewer, CiteSpace, bibliometrix (R package), SCImago Graphica Beta, and Pajek software.
Results: A total of 9,734 publications on TSCC were identified. The number of publications has shown a consistent increase, with the United States leading in terms of productivity, citation impact, centrality, and sigma values(centrality refers to its importance in the research network, and sigma values reflect its significant impact on the field). Sun Yat-sen University (China) is the most productive institution. Oral Oncology is the most influential journal, while SALO T is the most productive author. Keyword analysis indicates a decline in research on neck dissection, human papillomavirus, and diagnosis, while topics such as apoptosis and quality of life remain prominent. Emerging keywords include depth of invasion, biomarkers, and resistance. Co-citation analysis reveals a shift in research focus from traditional areas like E-cadherin, metastasis, and epidemiology to more recent topics such as depth of invasion, transoral robotic surgery, lymphatic spread, young patients, and tumor budding.
Conclusions: This is the first comprehensive bibliometric study of TSCC research, highlighting current trends and future directions. Clinical research dominates the field now, while emerging sub-fields include depth of invasion, biomarkers, transoral robotic surgery, young patients, and tumor budding, indicating potential future research areas. we provide insights into emerging research trends, helping to inform future research directions and strategies for TSCC prevention and treatment.
