Background: Latinas experience a greater number of symptoms and are at an elevated risk for depression and anxiety following a diagnosis of breast cancer compared to Non-Hispanic Whites and African Americans. Cancer-related symptom clusters are frequently reported in women with breast cancer and research suggests these women follow distinct trajectories for depression and anxiety. However, little is known about the trajectories of anxiety and depression or cancer-related symptom clusters in Latinas with breast cancer. Methods: 296 Latinas previously recruited and diagnosed with breast cancer comprised this sample. Questionnaires for depression (the Center for Epidemiological Studies-Depression) and Anxiety (Speilberger State-Trait Inventory and PROMIS Anxiety) were administered at baseline, 2 and 4 months post enrollment. To identify classes of Latina breast cancer survivors based on patterns of symptom occurrence, symptoms latent class analysis was used to describe symptom clusters. Group-based growth mixture modeling was utilized to identify classes of women who followed distinct trajectories of depression and anxiety. Results: On average women reported 4.2±3 symptoms with an overall symptom distress score of 6.4±2.5 (out of a scale of 10). Three symptom classes were identified: Weary and Sleepy (class 1), Weary (class 2) and Weary, Sleepy and Hurting (class 3). Women were most likely to cluster in class 1, followed by class 2 and 3 with fatigue (labeled weary) being the most prevalent symptom for all three classes. Three trajectories emerged for both depression and anxiety. For depression, the majority of women (79.6%) fell in the high then reducing trajectory for depression followed by the low and remaining low (17%) and the high and increasing (worsening) trajectories of depression (3%). For anxiety the majority (78% of women) followed the moderate to increasing (worsening) trajectory of anxiety followed by 14% in the moderate to declining (improving) and 8% in the low to slightly increasing (worsening) trajectories for anxiety. Conclusion: This study suggests Latina breast cancer survivors experience burdensome cancer-related symptom clusters and distinct trajectories for depression and anxiety. Further research is needed in minority women with breast cancer to adequately understand and treat cancer-related symptom clusters as well as depression and anxiety.
