Perceived stress, anxiety, and depression in treatment-naïve women with breast cancer: a case-control study
Menée en Chine par questionnaire auprès de 240 patientes atteintes d'un cancer du sein ou d'une maladie bénigne du sein et de 120 témoins, cette étude analyse l'association entre le cancer, le stress et des symptômes de dépression et d'anxiété
Objective : Women with breast cancer face elevated risk for psychological problems. We aimed to examine to what extent treatment-naïve women with breast cancer are at higher risk for perceived stress and symptoms of anxiety and depression, compared with matched women with benign breast disease and healthy women, and explore the contribution of perceived stress in the association between breast cancer and symptoms of anxiety and depression. Methods : The study included 360 women (120 per group). Perceived stress and symptoms of anxiety and depression were assessed using self-report questionnaires. We conducted linear and logistic regressions to assess increased risk and mediation analyses to test the role of perceived stress. Results : After adjusting for potential confounders, perceived stress in women with breast cancer was 0.71 and 1.58 points higher than in patients with benign breast disease (p = 0.028) and healthy controls (p < 0.001), respectively; they were 1.85–2.44 times more likely to experience anxiety than either control group and 3.57 times more likely to experience depression than healthy controls (p < 0.001). The indirect effect of perceived stress between breast cancer and anxiety and depressive symptoms was 0.19 to 0.47 (p < 0.05). Conclusions : This study demonstrates the high risk of perceived stress and symptoms of anxiety and depression in treatment-naïve patients with breast cancer, and the association between breast cancer and increased anxiety and depressive symptoms through elevated perceived stress. It underscores the need to assess psychological status in pre-treatment period and conduct stress-targeted prehabilitation interventions.This article is protected by copyright. All rights reserved.
