Bibliometric and visual analysis in the field of traditional Chinese medicine in cancer from 2002 to 2022

Objective: Traditional Chinese medicine (TCM) has been used as a complementary treatment for cancer patients, but there has been no quantitative comprehensive analysis of TCM's efficacy. The purpose of this paper is to explore the current status and hotspots of TCM in cancer research from 2002 to 2022 and to provide a reference for future research.Methods: We retrieved articles published between 2002 and 2022 from the Web of Science database and analyzed them using R software, VOSviewer, and CiteSpace software.Results: A total of 7,129 articles were included in this study. The publication rate of TCM cancer research increased steadily from 2002 to 2022, with a rapid increase from 2010 to 2021. China was the country with the most published articles, followed by the United States, Republic of Korea, Germany, and Japan. China was also the country with the most international collaborations, and China Medical University and Shanghai University of Traditional Chinese Medicine were the most representative cooperation centers. The Journal of Ethnopharmacology was the most published and cited journal. Apoptosis, expression, in vitro, activation, and other related keywords were commonly used in these articles. Breast cancer, colorectal cancer, gastric cancer, liver cancer, and lung cancer were the most studied cancer types in TCM research. Pathway-related apoptosis, anti-inflammation, and oxidative stress were the hotspots and trends of TCM's anti-cancer mechanism. Metabolomics combined with network pharmacology was the main research method.Conclusion: Traditional Chinese medicine as an anti-cancer drug has received increasing attention from researchers worldwide, and it is expected to be a hotspot for developing new anti-cancer drugs in the future. Our study provides a comprehensive analysis of the current status and hotspots of TCM cancer research, which could serve as a valuable reference for future studies.

Automated summary

This study analyzed the status and hotspots of traditional Chinese medicine (TCM) in cancer research from 2002 to 2022. The publication rate of TCM cancer research has been steadily increasing, with China being the leading country in terms of published articles and international collaborations. The most studied cancer types in TCM research are breast cancer, colorectal cancer, gastric cancer, liver cancer, and lung cancer. Pathway-related apoptosis, anti-inflammation, and oxidative stress are the hotspots in TCM's anti-cancer mechanism. Metabolomics combined with network pharmacology is the main research method.
