Abstract
Background: Understanding the change in emotional well-being (EWB) and functional well-being (FWB) in breast cancer survivors can facilitate targeted support for unmet needs.
Methods: Among 2,767 women with breast cancer in the Carolina Breast Cancer Study Phase 3, we assessed EWB and FWB with the Functional Assessment of Cancer Therapy - Breast instrument at 5 (baseline), 25, and 84 months after diagnosis. We identified well-being trajectories using latent class growth analysis, and relative frequency differences (RFD) with 95% confidence intervals (CI) were estimated for associations between trajectory group membership and demographic or clinical characteristics.
Results: Five trajectory groups were identified for both EWB and FWB. Most participants (∼70%) were classified into "good well-being" ("stable high" or "stable medium"). A small percentage (∼10%) fell into "very low baseline" or "early decrease", and the rest were "stable low" (∼20%). Overall, younger vs. older age was associated with "stable low" EWB (25.4% vs. 19.3%; RFD 6.1%; 95% CI, 3.0%-9.2%). Black participants more frequently had "stable low" FWB (24.2% vs. 16.6%; RFD 7.6%; 95% CI, 4.6%-10.6%). Breast cancer recurrence was strongly associated with "stable low" EWB (28.7% vs. 21.3%; RFD 7.3%; 95% CI, 2.3%-12.3%) and FWB (28.7% vs. 19.2%; RFD 8.6%; 95% CI, 3.7%-13.5%). Being unmarried, lower income, having nonprivate insurance, advanced stage, mastectomy vs. breast conservation surgery, and chemotherapy were also predictors of poor well-being trajectories.
Conclusions: Demographics and clinical features are associated with sustained poor well-being after breast cancer.
Impact: Improvements in long-term well-being may warrant targeted support.
期刊介绍:
Cancer Epidemiology, Biomarkers & Prevention publishes original peer-reviewed, population-based research on cancer etiology, prevention, surveillance, and survivorship. The following topics are of special interest: descriptive, analytical, and molecular epidemiology; biomarkers including assay development, validation, and application; chemoprevention and other types of prevention research in the context of descriptive and observational studies; the role of behavioral factors in cancer etiology and prevention; survivorship studies; risk factors; implementation science and cancer care delivery; and the science of cancer health disparities. Besides welcoming manuscripts that address individual subjects in any of the relevant disciplines, CEBP editors encourage the submission of manuscripts with a transdisciplinary approach.
