Unraveling the vicious cycle: longitudinal analysis between financial toxicity and symptom burden in women with breast cancer
摘要
Financial toxicity (FT) from cancer treatment significantly impacts the quality of life among breast cancer patients. The study aimed to assess the longitudinal associations between FT and symptom burden in Chinese breast cancer patients.
MethodsThis prospective cohort study was conducted from November 2022 to March 2024. Participants were recruited from four Grade-A public hospitals across different areas of China using convenience sampling. FT was assessed using the Comprehensive Score for Financial Toxicity, with higher scores indicating better financial well-being. Symptom burden was measured with the BCPT (Breast Cancer Prevention Trial) Eight Symptom Scale and the Memorial Symptom Assessment Scale–Short Form Psychological Subscales, with higher scores indicating greater psychological symptom burden. Assessments were conducted at baseline (T1), 3 months (T2), 6 months (T3), and 12 months (T4) post-surgery.
ResultsAmong 378 participants (all women; mean [SD] age, 48.9 [9.97] years), a moderate negative association was found between physical symptom burden and FT (r = −0.498 to −0.411) and between psychological symptom burden and FT (r = −0.493 to −0.392). Random Intercept Cross-lagged Panel Model demonstrated that FT negatively predicted the subsequent physical symptom burden (r = −0.166 to −0.122, p < 0.05). Physical symptom burden at T1 and T3 also negatively predicted the subsequent FT (r = −0.294 to −0.186, p < 0.05). Additionally, psychological symptom burden negatively predicted FT at the subsequent time point (r = −0.116 to −0.069, p < 0.05).
ConclusionsThis study found vicious associations between FT and symptom burden in breast cancer patients. Future interventions addressing FT should incorporate the monitoring and management of symptom burden.
