Abstract
Fatigue is one of the most frequent symptoms in cancer patients. However, t he precise causes of this fatigue are still unknown, and this situation mak es it difficult to combat the problem. The present study was conducted to i nvestigate factors correlated with fatigue in disease-free breast cancer pa tients. A group of 134 randomly selected ambulatory breast cancer patients who had undergone successful surgical treatment participated. They complete d the Cancer Fatigue Scale, the Hospital Anxiety and Depression Scale, the Mental Adjustment to Cancer Scale, and an ad hoc questionnaire detailing ph ysical symptoms, social support, and demographic variables at home and retu rned them by mail the following day. Multiple regression analysis revealed that fatigue was significantly correlated with dyspnea, insufficient sleep, and depression, and that these three variables accounted for a total of 46 % of variance in fatigue. Factors concerned with the cancer and treatment, such as disease stage, lymph node metastasis, number of days since operatio n, past intravenous chemotherapy, radiotherapy, current use of fluoropyrimi dine compounds, and current use of tamoxifen citrate were not correlated wi th fatigue. The results suggest that fatigue in this population is determin ed by current physical and psychological distress rather than by the cancer itself and prior cancer treatments, and that the manage ment of dyspnea, i nsomnia, and depression might be important in reducing fatigue in this popu lation.
