Correlation between symptom experience and fear of cancer recurrence in postoperative breast cancer patients undergoing chemotherapy in China: A cross-sectional study.

OBJECTIVE: To analyze the relationship between experience of symptoms (e.g., pain, fatigue) and fear of cancer recurrence (FCR) in Chinese postoperative patients with breast cancer undergoing chemotherapy. METHODS: A total of 225 patients were recruited using convenience sampling. The Fear of Cancer Recurrence Inventory-Chinese Version and the Symptom Experience Index were used to collect data. The Mann-Whitney U test, Spearman's correlation, and multivariate analysis were employed to explore the relationships between symptom experience and FCR. RESULTS: The total Fear of Cancer Recurrence Inventory score in postoperative patients with breast cancer undergoing chemotherapy was 43.19±22.83, and >64.0% of participants exhibited significant fear of cancer recurrence. The total score of symptom experience was 27.41±16.77, including scores of symptom severity (16.91±8.70) and symptom distress (10.50±8.89). Participants' symptom experience was positively correlated with fear of cancer recurrence (r = 0.353, P < 0.001). Patients with clinically relevant FCR had higher scores for total symptom experience (Z = -3.911, P<0.001), symptom severity (Z = -3.245, P = 0.001), and symptom distress (Z = -4.185, P<0.001), compared to patients without clinically relevant FCR. Symptom experience (b = 0.511, t = 6.474, P<0.001), age (b = -0.591, t = -4.201, P<0.001), and educational level (b = 4.147, t = 3.955, P<0.001) were statistically correlated with FCR, accounting for 27.0% of the variance. Among these variables, symptom experience demonstrated the strongest correlation, with a beta value of 0.371. CONCLUSION: This study followed others in identifying a cross-sectional relationship between symptom experience and FCR. Further prospective research is required to better understand the nature of this relationship.

Effects of sleep disturbance, cancer-related fatigue, and psychological distress on breast cancer patients' quality of life: a prospective longitudinal observational study.

More attention has gone to researching the cancer-related fatigue (CRF)-sleep disturbance (SD)-psychological distress (PD) symptom cluster in breast cancer patients during the chemotherapy period, but the change trend and heterogeneous development track in the whole treatment stage remain unclear, and it is also unclear whether the appearance of and changes in one symptom cause changes in other symptoms and quality of life (QoL). This study, using breast cancer patients' data collected through a validated questionnaire, examined the relationships between SD, CRF, PD, and QoL using latent growth modeling analyses. CRF developmental trajectories showed an upward trend over five surveys (slope = 0.649, P < 0.001); PD showed a significant weakening trend (slope = - 0.583, P < 0.001); SD showed an increasing trend (slope = 0.345, P < 0.001), and QoL showed a statistically significant weakening trend (slope = - 0.373, P < 0.001). The initial CRF (coefficient = - 0.233, P < 0.01), PD (coefficient = - 0.296, P < 0.01), and SD (coefficient = - 0.388, P < 0.001) levels had a statistically significant negative effect on initial QoL level. The linear development rate of PD was statistically significant and negatively affected that of QoL (coefficient = - 0.305, P < 0.05), whereas the quadratic development rate of SD negatively affected that of QoL (coefficient = - 0.391, P < 0.05). Medical staff should identify the change characteristics of different variables based on SD, CRF, PD, and QoL change trajectories, and advance the intervention time, as changes in variables affect other variables' subsequent changes.
