A Prospective Multi-modal Cohort Study of Local Treatment-related Toxicities and Quality of Life in Chinese Breast Cancer Patients PERSEVERE

What this Trial Is About

Researchers are studying the effects of local treatment on health and daily life in people with early-stage breast cancer in China. The focus is on those with stage I to III invasive breast cancer receiving surgery and other therapies before or after surgery. The study aims to understand both short- and long-term physical, emotional, and social effects of treatment, including tiredness, sleep problems, emotional distress, pain, and changes in heart or lung function, to improve recovery and quality of life. Participants will receive local therapy with curative intent, which may include surgery, chemotherapy, radiotherapy, endocrine therapy, or targeted therapy given before or after surgery. This observational study involves no experimental treatment. At the start, participants undergo clinical assessments, including heart and lung tests, lab work, and collection of blood and tissue samples. They also complete questionnaires about symptoms and well-being at multiple time points over five years. During the study, participants will complete surveys about their physical symptoms, emotional health, and quality of life at baseline, one week, one month, three months, six months, one year, and then annually up to five years. Researchers will monitor treatment-related toxicities and quality of life changes through these patient-reported outcomes. The study uses electronic data collection with quality checks to ensure accurate and consistent information for analysis and future research.
