Chemotherapy-induced peripheral neuropathy onset is associated with early risk of depression and anxiety in breast cancer survivors
Menée à partir de données portant sur des patientes ayant survécu à un cancer du sein, cette étude de cohorte rétrospective analyse l'association entre une neuropathie périphérique induite par la chimiothérapie et le risque de dépression et d'anxiété
Objective : The objective was to assess for an association between chemotherapy-induced peripheral neuropathy (CIPN) onset and development of depression and anxiety in breast cancer (BrCa) survivors. Methods : A retrospective observational cohort was used and identified from Optum's De-identified Clinformatics® Data Mart Database years 2012–2015. Three groups of women were derived based on BrCa and CIPN status: BrCa+/CIPN+ (n = 244), BrCa+/CIPN− (n = 8870), and BrCa−/CIPN− (n = 1,125,711). The ratio of the prevalence ratios (RPR) determined if the change in risk of depression and anxiety from the 12-month preindex period to postindex period I (0–6 months) and II (7–12 months) was different for BrCa+/CIPN+ compared to BrCa+/CIPN− and BrCa−/CIPN−. Results : The adjusted RPR for depression was significantly elevated for BrCa+/CIPN+ compared to BrCa+/CIPN− and BrCa−/CIPN− for postindex periods I (RPR = 1.35 [1.10,1.65] and 1.33 [1.08,1.63], respectively) and II (RPR = 1.53 [1.21,1.94] and 1.50 [1.17,1.93], respectively). The RPR for anxiety was significantly elevated for BrCa+/CIPN+ compared to BrCa+/CIPN− and BrCa−/CIPN− for postindex periods I (RPR = 1.37 [1.12,1.67] and 1.31 [1.06,1.61], respectively) and II (RPR = 1.41 [1.13,1.76] and 1.28 [1.02,1.62], respectively). Conclusions : Among BrCa survivors, CIPN onset is associated with a subsequent increased 12-month risk of depression and anxiety. Depression and anxiety screening should be considered in BrCa+/CIPN+ survivors, particularly given their known impact on fall risk. The observed association between CIPN and an increased risk of depression and anxiety should be further studied in prospective studies.
