Purpose: To identify potential correlates of cancer-related fatigue (CRF) after curative breast cancer (BC) treatment. The hypothesis was that fatigue would be more severe among women treated with cardiotoxic drugs, with poor physical condition and those who exercised less.
Methods: Observational cross-sectional design. Fatigue was evaluated through PERFORM Questionnaire (multi-item, multi-dimensional). Patient-reported assessments and objective information regarding clinical data, physical activity (PA) and physical condition were analysed as potential correlates of CRF.
Results: One hundred eighty women who remained free of disease were recruited. The prevalence of fatigue interfering with quality of life was 43%. Weight, resting and recovery heart rate were positively associated with fatigue. Age and time from diagnosis were negatively associated. Previous therapies, objectively assessed weekly PA, cardiorespiratory condition, muscular strength and adherence to Mediterranean diet were not associated with CRF.
Conclusions: CRF is a prevalent problem after BC treatment. Objectively assessed PA, cardiorespiratory fitness and muscular strength did not predict CRF. The association of heart rate and fatigue deserves a further insight. Future research should include longitudinal studies and determination of biomarkers.
Implications For Cancer Survivors: BC survivors, especially younger and overweight women, should be informed about fatigue as a potential persistent symptom through all stages of the cancer trajectory and into survivorship. They also should be routinely screened for CRF.
