Objective: To explore changes in the symptom clusters of perioperatively elderly patients with lung cancer at different time points (i.e., the day of admission [T0]), 2-4 days after surgery [T1], 1 month after discharge [T2] and 3 months after discharge [T3]) and to analyze correlations between cluster severity, frailty and quality of life (QOL).
Methods: A longitudinal study was conducted from August 2020 to June 2021 among elderly lung cancer patients undergoing surgery at hospitals in Jiangsu Province. Data were collected using the Chinese Tilburg Frailty Indicator, the MD Anderson Symptom Inventory and the Quality of Life-Core scale.
Results: According to exploratory factor analysis, a total of 5 symptom clusters were found and three of them (the global mental function symptom cluster, the special mental function symptom cluster and the respiratory function symptom cluster) were persistent. The incidence of the top four symptoms varied at different time points. The severity of symptom clusters at different time points was positively correlated with frailty and negatively correlated with QOL.
Conclusions: The findings may serve as a reference for medical staff to implement symptom management in elderly lung cancer patients after surgery. Frailty may be an important variable affecting the severity of symptom clusters and the QOL of patients.
