ASO Visual Abstract: The Trajectory of Cancer-Related Fatigue and Its Associating Factors in Patients with Esophageal Cancer Receiving Treatments—A Prospective, Longitudinal Study

Background Cancer-related fatigue (CRF) is the most distressing symptom in the overall cancer population. For patients with esophageal cancer, CRF may even be harder to predict and control due to its complicated and prolonged treatment. Moreover, communication difficulties due to disease progression or treatment may further diminish esophageal cancer patients’ ability to communicate about CRF. However, little research has addressed the trajectory and associating factors of CRF in this population, especially during the active treatment phase. The purpose of this study was (1) to evaluate and compare the level of CRF at three time points, namely before treatment, a month after concurrent chemoradiotherapy (CCRT), and a week after surgery, and (2) to identify associated factors of CRF. Methods This prospective cohort study used a questionnaire to evaluate esophageal cancer patients’ CRF at three time points. Repeated measures ANOVA and linear regression were used to analyze the data. Results This study included 73 participants. The severity of all CRF aspects intensified significantly over the course of treatment, reaching the highest level after surgery ( P < 0.001). Worries of physician invalidation at baseline ( P < 0.05) and marital status associated with CRF after CCRT and after surgery. Conclusions This is the first study to demonstrate the relationship between CRF and physician invalidation. Clinicians must be aware of the intensifying trend of CRF and provide timely intervention when caring for patients with esophageal cancer during cancer treatment. Reducing the worries of physician invalidation may alleviate CRF.
