Depression and anxiety in colorectal cancer patients: Ties to pain, fatigue, and inflammation

Menée aux Etats-Unis par questionnaire auprès de 88 patients atteints d'un cancer colorectal, cette étude analyse l'association entre des symptômes d'anxiété ou de dépression et l'intensité de la douleur, de la fatigue ou le niveau de protéine C réactive

Résumé en anglais

Objective : Colorectal cancer poses a significant threat to both psychological and physical health. This study examined relationships between anxiety and depressive symptoms with pain, fatigue, and inflammation among colorectal patients.

Methods : Colorectal cancer patients (n = 88, stages 0-IV) completed a laboratory-based study visit before undergoing adjuvant cancer treatment. Patients completed questionnaires assessing depressive, anxiety, pain, and fatigue symptoms. A blood sample was also collected to measure c-reactive protein (CRP). Analyses controlled for age, sex, cancer stage, body mass index (BMI), and menopause status.

Results : Multiple linear regression analyses showed colorectal patients with higher depressive and anxiety symptoms had greater pain, fatigue, and CRP (ps < .03). Approximately one-third of patients with clinically significant depressive (CESD > 16) and anxiety symptoms (BAI > 16) also had clinically-elevated levels of CRP ( > 3mg/L) (ps = .02).

Conclusion : These results extend findings from other cancer subgroups showing heightened symptom burden among patients with depression and anxiety. They also highlight the detrimental role that elevated anxiety and depressive symptoms may play in the physical and biological side effects associated with colorectal cancer.
