Patients were recruited from oncology practices in Los Angeles to participate in a longitudinal, observational study of cancer-related fatigue (RISE study). Women were eligible if they had been recently diagnosed with Stage 0-IIIA breast cancer and had not yet started adjuvant or neoadjuvant therapy with radiation, chemotherapy, or endocrine therapy. Primary recruitment sites were UCLA and Cedars Sinai Medical Center (CSMC).
Participants completed assessments at baseline, end of treatment (for those who received radiation and/or chemotherapy), and at 6, 12, and 18 month post-treatment follow-ups; we focus here on the baseline assessment. The Institutional Review Boards at UCLA and CSMC approved the study, and all participants provided written informed consent.
