Abstract

Background

The causes of cancer-related fatigue, which can influence patients’ activities, are multidimensional; however, little is known about the cognitive dimension. We examined the association of cognitive fatigue with menopause, depressive symptoms, and quality of life in ambulatory breast cancer patients after primary treatment.

Methods

This descriptive, cross-sectional study recruited 20–64-year-old breast cancer patients in an outpatient setting. The patients (N = 93; mean age = 53 years) were divided into low (L-CogF) and high-cognitive fatigue (H-CogF) groups according to their scores on the cognitive fatigue subscale of the Cancer Fatigue Scale. We compared the groups on their sociodemographic and medical characteristics and scores on the Functional Assessment of Cancer Therapy-Breast (FACT-B) [a measure of quality of life (QOL)], Simplified Menopausal Index (SMI), and Self-Rating Questionnaire for Depression (SRQ-D).

Results

The L-CogF (n = 55) and H-CogF (n = 38) patients did not differ in age, years since diagnosis, marital status, educational background, or treatment history. Total and subscale FACT-B scores, except for physical well-being, were significantly lower in H-CogF participants than in L-CogF participants. SMI and SRQ-D scores were significantly higher in H-CogF participants. Employed H-CogF participants were concerned about keeping their jobs (p < 0.05).

Conclusions

Breast cancer patients with high-cognitive fatigue suffer from severe menopause and depressive symptoms, and deteriorating QOL. Cognitive fatigue should be considered when interpreting patients’ cognitive complaints.
