Symptom burden in advanced breast cancer patients and its association between death anxiety and psychological distress

doi: 10.21147/j.issn.1000-9604.2022.03.09

ObjectiveRecent research has documented psychological distress in advanced breast cancer (ABC) patients, but few studies have examined how death anxiety is affected by the symptom burden. Therefore, this study aims to explore the association among symptom burden, death anxiety and psychological distress (depression and anxiety) in ABC patients.MethodsThis cross-sectional study used the Death and Dying Anxiety Scale (DADDS), 9-item Patient Health Questionnaire (PHQ-9), General Anxiety Disorder-7 (GAD-7) and MD Anderson Symptom Inventory (MDASI) to assess death anxiety, depression, anxiety, and symptom burden, respectively. Bias-corrected bootstrapping methods were used to estimate indirect effects and 95% confidence intervals.ResultsTwo hundred ABC patients completed the questionnaires. All of the respondents were females, with a mean age of 50±10 years. Initial correlation analyses revealed significant associations of death anxiety with depression (r=0.57, P<0.001), anxiety (r=0.60, P<0.001) and symptom burden (r=0.43, P<0.001). Moreover, depression (r=0.53, P<0.001) and anxiety (r=0.45, P<0.001) were significantly correlated with symptom burden. An analysis using Hayes’ PROCESS macro revealed the partial effecting role of death anxiety in the relationship between depression and symptom burden, and between anxiety and symptom burden (contributions to the total effect of 0.247 and 0.469, respectively).ConclusionsThis study provides insight into the relationship between death anxiety and symptom burden. The results suggest that interventions addressing death anxiety may be more effective for alleviating the depression and anxiety experienced by ABC patients with a symptom burden.

Psychosomatic symptoms affect radiotherapy setup errors in early breast cancer patients

doi: 10.21147/j.issn.1000-9604.2021.03.04

ObjectiveTo examine the trajectory of psychosomatic symptoms and to explore the impact of psychosomatic symptoms on setup error in patients undergoing breast cancer radiotherapy.MethodsA total of 102 patients with early breast cancer who received initial radiotherapy were consecutively recruited. The M.D. Anderson Symptom Inventory (MDASI) and three different anxiety scales, i.e., the Self-Rating Anxiety Scale (SAS), State-Trait Anxiety Inventory (STAI), and Anxiety Sensitivity Index (ASI), were used in this study. The radiotherapy setup errors were measured in millimetres by comparing the real-time isocratic verification film during radiotherapy with the digitally reconstructed radiograph (DRR). Patients completed the assessment at three time points: before the initial radiotherapy (T1), before the middle radiotherapy (T2), and before the last radiotherapy (T3).ResultsThe SAS and STAI-State scores of breast cancer patients at T1 were significantly higher than those at T2 and T3 (F=24.44, P<0.001; F=30.25, P<0.001). The core symptoms of MDASI were positively correlated with anxiety severity. The setup errors of patients with high SAS scores were greater than those of patients with low anxiety levels at T1 (Z=−2.01, P=0.044). We also found that higher SAS scores were associated with a higher risk of radiotherapy setup errors at T1 (B=0.458, P<0.05).ConclusionsThis study seeks to identify treatment-related psychosomatic symptoms and mitigate their impact on patients and treatment. Patients with early breast cancer experienced the highest level of anxiety before the initial radiotherapy, and then, anxiety levels declined. Patients with high somatic symptoms of anxiety may have a higher risk of radiotherapy setup errors.
