Bibliometric visualization analysis based on thecorrelation between cancer pain and psychosocialfactors

Cancer pain, a complex sensation influenced by psychological and social factors, negatively impacts patients' quality of life and prognosis. Current treatments are often unsatisfactory, partly because key psychosocial factors remain unidentified, creating a barrier to effective care. Further research is needed. This study uses bibliometric analysis and latent Dirichlet allocation (LDA) topic modeling to examine the current research landscape, identify conceptual associations, and uncover unexplored links.

A comprehensive literature search on cancer pain and psychosocial factors was conducted in the Web of Science database. Bibliometric visualization analysis was performed on the published studies using Citespace, VOSviewer, the bibliometrix package in R, and KH Coder software.

Research on cancer pain and psychosocial factors has shown phased growth, intersecting medicine, biology, psychology, and other fields. Most studies have focused on pain management, quality of life, and psychological impact, with the USA leading global research with 184 publications. Institutions such as Duke University and influential authors such as Breitbart and Bruera have propelled development in this field. The Journal of Pain and Symptom Management-an academic pillar among journals publishing research on cancer pain-is the most cited. Research hotspots have shifted from early "prevalence" and "management" to "quality of life" and "depression." LDA topic modeling identified four major research directions: quality of life and treatment outcomes, pain management and treatment of cancer pain, cancer pain in special populations and contexts, and the multidimensional aspects of cancer pain and its coping strategies.

Cancer pain and psychosocial research is a valuable, US-led field with strong international collaboration. The focus has moved from pain management to mental health and quality of life. Future priorities include strengthening multidisciplinary cooperation, exploring molecular mechanisms, and using psychological interventions to achieve personalized, standardized management.
