Co-word clustering analysis of cognitive dysfunction research hotspots in colorectal cancer patients

Objective To analyze the research hotspots and trends of colorectal cancer cognitive dysfunction at home and abroad，and to provide a reference for the research. Methods The relevant literature on cognitive dysfunction of colorectal cancer collected from CNKI and Web of Science was retrieved and visually analyzed by CiteSpace software from the establishment of the databases to February 2022. Results CNKI and Web of Sciene finally included 245 and 203 articles respectively，and the overall number of published articles showed an upward trend. CNKI database obtained a total of 8 clusters and 11 emerging keywords，and Web of Sciene database obtained a total of 17 clusters and 4 emerging keywords. Conclusion The cognitive function of elderly colorectal cancer patients undergoing laparoscopic surgery has been a research hotspot at home and abroad in the past 13 years. Predictive models are constructed through risk factors. Folic acid levels are improved through dietary nursing care，and the exercise intervention program integrated with multidisciplines is a possible trend in the future.
