RESUMO
AIM: To investigate symptom clusters and sentinel symptoms in breast cancer survivors based on self-reported outcomes, explore the impact of sentinel symptoms on patients' quality of life and psychological distress, provide a basis for implementing accurate symptom management. DESIGN: A cross-sectional survey. METHODS: The study was conducted from September 2021 to December 2022. We recruited 281 patients who were re-examined in an outpatient department of a tertiary hospital in Hebei Province. The European Organization for the Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire - Core30 (QLQ-C30), the EORTC Quality-of-Life Questionnaire Breast Cancer - 23 (QLQ-BR23), the Hospital Anxiety and Depression Scale (HADS) were used to conduct the survey. Symptom clusters were explored using principal component analysis, sentinel symptoms were explored using the Apriori algorithm. Correlation analysis was used to explore the relationship between sentinel symptoms and quality of life, correlation with psychological distress. This paper adhered to the STROBE guidelines. RESULTS: Breast cancer survivors have a wide range of self-reported symptoms in the form of four symptom clusters: a fatigue symptom cluster, a gastrointestinal symptom cluster, a sickness symptom cluster and a surgical trauma-related symptom cluster. Three sentinel symptoms were explored: pain, alopecia and limited function of the upper limbs. Except for sexual function, all of the sentinel symptoms were negatively correlated with patients' quality of life and positively correlated with psychological distress (p < .05). CONCLUSIONS: Breast cancer survivors have a variety of symptoms in the form of four symptom clusters. Pain, alopecia and limited function of the upper limbs are the sentinel symptoms, which affect patients' quality of life and psychological distress.
RESUMO
BACKGROUND: We investigated the effectiveness of one education course to lower the severity of anxiety and depression symptoms among breast cancer (BC) patients during radiotherapy (RT). METHODS: All 290 one-sided BC patients were evenly randomized into intervention or control arm. "Intervention" patient was additionally provided with one three-hour course on psychological stresses and management skills. Changes of anxiety and depression score and their 3-level severity category ('normal', 'borderline' and 'abnormal' scored 0-7, 8-10 and 11-21, respectively) from HADS questionnaire over RT were evaluated by multivariable linear and ordinal logistic regressions. RESULTS: Response rates were 94 and 100% by "intervention" and "control" arm, respectively. Means of score changes by "intervention" and "control" (n = 145) were + 0.59 (SD = 2.47) and + 0.11 (SD = 2.55) for anxiety and + 0.81 (SD = 2.81) and + 0.45 (SD = 2.77) for depression scores, respectively. 'Abnormal' anxiety and depression patients were 4.1 and 6.9% at baseline and 4.8 and 6.9% at end of RT at 'control' arm; those rates were 6.6 and 7.4%, and 8.8 and 10.3% at 'intervention' arm, respectively. Both changes on anxiety and depression measurements between two arms were all insignificant (p > 0.20). CONCLUSIONS: One education course did not reduce the score and severity of anxiety and depression symptoms over RT period.
