Global trends of research on depression in breast cancer: A bibliometric study based on VOSviewer

Abstract

BackgroundDepression is common psychiatric morbidity in breast cancer survivors, seriously affecting patients’ quality of life and mental health. A growing body of research has investigated depression in breast cancer. However, no visual bibliometric analysis was conducted in this field. This study aimed to visualize the literature to identify hotspots and frontiers in research on breast cancer and depression.MethodsThe publications related to depression in breast cancer were retrieved in the Web of Science Core Collection between 1 January 2002 and 17 March 2022. VOSviewer was used to identify co-occurrences and collaborations among countries, institutions, and keywords. CiteSpace was used to detect keyword bursts.ResultsA total of 7,350 articles and reviews related to depression in breast cancer were identified. From 2002 to 2022, the United States and the People’s Republic of China were the most productive countries in this field. The University of California, Los Angeles, and the University of Toronto were the most productive institutions in this field. The Journal of Psycho-oncology, followed by Supportive Care in Cancer and the Journal of Clinical Oncology, had the most publications on depression in breast cancer. Of the top 10 journals, seven were from the United States, two were from England, and one was from Germany. Five research hotspots of depression in breast cancer were identified by co-word analysis. Research on post-traumatic growth, spiritual interventions, cognitive-behavioral therapy, physical activity, and symptom cluster management of depression in breast cancer was relatively mature in the core hotspots. Burst detection of keywords on depression in breast cancer showed the latest hotspots, such as mental health, cancer survivor mortality, and activity.ConclusionThe research on depression in breast cancer is growing. Attention should be paid to the latest hotspots, such as mental health, cancer survivor, mortality, exercise, and physical activity.

Improved awareness of physical activities is associated with a gain of fitness and a stable body weight in breast cancer patients during the first year of antineoplastic therapy: the BEGYN-1 study

“…We hypothesize that addressing the positive effects of physical activity during the initial disclosure of the diagnosis was perceived by the patients as a possibility to take control over the course of the disease and improve the feeling of self-efficiency. This has been shown to have a long-lasting positive effect on the psychological coping with the disease and to correlate with an improved outcome ( 47 ). The effect of higher self-efficiency and autonomy in cancer patients undergoing counseling for physical activity has been previously shown in different cancer entities ( 48 ).…”

Uncovering the dark side of the sharing economy from a provider’s perspective: a bibliometric systematic review

“…It can visualize the association between various terms and create a set of clusters that effectively illustrate the main relationships that have been studied (Pinillos et al , 2022; Ravikumar et al , 2015). By examining the co-occurrence of keywords, we can identify the main research themes in the topic, the core content in each cluster, as well as the developing trends of the topic (Chen et al , 2022).…”

Humanistic Health Management and Cancer: Associations of Psychology, Nutrition, and Exercise with Cancer Progression and Pathogenesis

“…[ 14 ] Physiological and immune changes caused by depression are closely related to tumor recurrence and death, such as breast cancer patients with depression have a 30% higher risk of death than normal breast cancer, and the risk of recurrence is 24% higher than normal breast cancer. [ 15 ]…”
