Background and purpose
Cancer-related fatigue (CRF) is a common side effect of cancer treatment, particularly in breast cancer patients. Over the past decade, the multimodal management of breast cancer has undergone several changes, such as the establishment of postoperative hypofractionated radiotherapy (RT) as a new standard protocol and the reduced use of chemotherapy. The aim of the current study was to investigate the impact of these changes on quality of life (QoL) and CRF.
Methods
A total of 66 patients was assessed for QoL and CRF using the FACIT‑F questionnaire. Patients were asked to complete the paper-based questionnaire before (TP1) and at the end of radiotherapy (TP2) as well as at follow-up (TP3). Subgroups were compared based on fractionation and previous application of chemotherapy.
Results
For the entire cohort, no significant changes in the severity of fatigue were seen. A mild decrease of physical wellbeing (PWB) from TP1 to TP2 was observed (22.2 vs. 20.7, p = 0.007). Fatigue at TP1 was more severe in patients receiving chemotherapy before RT (37.9 vs. 30.5, p = 0.041). Only patients without preceding chemotherapy showed a significant worsening of fatigue from TP1 to TP2 (37.9 vs 34.8, p = 0.005). The same is true for physical wellbeing (PWB), with a decrease from TP1 to TP2 in chemotherapy-naïve patients only (23.5 vs. 21.4, p = 0.002). Fractionation did not impact any of the investigated endpoints.
Conclusion
Patients undergoing postoperative RT for breast cancer constitute a heterogeneous patient population with varying risks of developing CRF influenced by previous treatments. Therefore, patient selection seems to be critical when interventional studies addressing CRF during radiotherapy are designed.
