N2 - Context: Symptoms are reported to co-occur during treatment for breast cancer. We previously identified three patterns of fatigue and two patterns of disturbed sleep, depressed mood, and anxiety in women undergoing chemotherapy for breast cancer using a Latent Growth Mixture Model. Objectives: The purpose of this study was to explore whether membership in symptom classes of fatigue, disturbed sleep, depressed mood, and anxiety is associated with other symptoms at moderate-to-severe levels. Methods: Using data from three longitudinal studies, Wilcoxon rank-sum tests and Jonckheere-Terpstra tests for trend were used to distinguish between classes of women on co-occurring symptoms. Summative scores were calculated, including the number of days subjects reported moderate-to-severe levels (4 or higher on a 0–10 scale) of seven symptoms during two cycles of chemotherapy and compared to class membership. Results: Participants (n = 166) in the higher fatigue severity class reported more days with moderate-to-severe disturbed sleep, depressed mood, anxiety, nausea, and trouble thinking. Women in the higher severity disturbed sleep class reported more days with moderate-to-severe fatigue, depressed mood, anxiety, and trouble thinking. Women in the higher depressed mood severity class reported more days with moderate-to-severe fatigue, disturbed sleep, anxiety, and nausea. Women in the higher anxiety severity class reported more days with moderate-to-severe fatigue, disturbed sleep, and depressed mood. Conclusion: Moderate-to-severe symptoms co-occur during cancer treatment for breast cancer. The dynamic process of multiple symptoms may be altered by future identification of a shared etiology.
