Purpose: Fatigue after treatment for breast cancer is common, but is also prevalent in people with chronic diseases such as heart failure, diabetes, and depression etc. The primary objective was to compare the level of fatigue between BC patients one year after end of treatment with data from a representative survey of the Norwegian population (GenPop). Secondary aim was to explore the association between chronic conditions and fatigue and in both samples. Design and Method: 245 patients treated with chemo –and/or radiotherapy after surgery, were assessed one year after treatment. Comorbidity was recorded by clinical examinations in patients and by self-report in the GenPop (N = 652). Fatigue was measured by the 3-item subscale of the EORTC QLQ-C30, with higher scores on the 0–100 scale implying more fatigue. Analysis of covariance was applied to compare age-adjusted mean scores between groups. Results: Mean age was 58 (9) years in patients and 52 (14) years in GenPop. 23% of patients and 32% of GenPop had one or more of the following conditions; cardiovascular- or pulmonary disease, diabetes or depression. No significant differences were found in fatigue between BC patients and GenPop (mean score 26.7 vs. 29.7). Comorbidity was the greatest determinant of increased fatigue, regardless of BC treatment. Patients with comorbidity were significantly more fatigued than those without comorbidity (mean difference 10.4), as found in the GenPop (mean difference 13.3). Conclusion: Similar fatigue levels in BC patients and GenPop one year after treatment is promising, but longer follow-up is needed. Comorbidity conditions should always be assessed when evaluating fatigue and other patient related outcomes. Prevention or treatment of common chronic conditions might be considered in rehabilitation programs to reduce fatigue in cancer survivors.
