Abstract

|
|
Purpose: This study aimed to understand the knowledge structure and trends in research on cancer-relatedcognitive impairment (CRCI) in patients with non-central nervous system (non-CNS) cancer through text networkanalysis and topic modeling.
Methods: From 2011 to 2021, studies on CRCI in patients with non-CNS cancerregistered in databases including Ovid-MEDLINE, EMBASE, Cochrane, CINAHL, CENTRAL, and PsycInfo, wereextracted and cleaned into words using Python¡¯s natural language toolkit package. Text network analysis wasperformed using the NetworkX library, and topic modeling analysis based on the latent Dirichlet allocationalgorithm was carried out using the Gensim library.
Results: In total, 24,030 keywords were extracted from theabstracts of 490 selected papers, of which ¡°chemotherapy,¡± ¡°breast cancer,¡± and ¡°quality of life¡± showed highfrequency and centrality. As a result of the topic modeling analysis, four subject groups were derived, includingcognitive impairment due to chemotherapy, breast cancer and cognitive impairment, factors related to cognitiveimpairment, and symptom experience.
Conclusion: These findings will help cancer researchers to understand thetrends and insights of research on CRCI in patients with non-CNS cancer and suggest important areas anddirections for future studies.
