Bibliometric analysis on randomized controlled trials of colorectal cancer over the last decade

Background The aim of this bibliometric analysis was to evaluate the clinical trials of randomized controlled trials (RCTs) of colorectal cancer all the world over the past decade. Methods The PubMed and Web of Science database were searched to obtain a randomized controlled trial of colorectal cancer from January 1, 2008 to January 1, 2018.The included literatures were analyzed with the bibliometric analysis. Results In the past 10 years, Randomized controlled trials of colorectal cancer have shown an upward trend; Most of the top ten research institutions in the literature are from the USA, the UK and other regions which has the high incidence of colorectal cancer; Most of the related research journals are also sponsored by European and American countries; the frequently cited top 15 literatures are mostly international multi-center clinical research, and there are fewer participants in Chinese research institutions. By keyword co-occurrence, colorectal cancer research mostly involves screening, disease-free survival, drug treatment, surgical methods, clinical trials, quality of life and prognosis; The results of the co-authorship network analysis show that Chinese researchers are less involved in international cooperation. Conclusions High-quality randomized controlled trials are increasingly favored by top international journals. However, there is still a large gap in clinical research between China and abroad. Researchers should gradually implement the standardization and accuracy of clinical trials, strengthen international multi-center cooperation and emphasize quality control.
