Tracking body composition changes after breast cancer treatment

Long-term Evaluation of the Body Composition and the Impact of Resistance and Relaxation Exercise on Muscle Mass and Quality of Life in Patients With Breast Cancer

Observational Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation · NCT07472803

What this trial studies

This is a longitudinal observational cohort that will follow patients from shortly after diagnosis through two years of post-treatment recovery, with serial measurements of skeletal muscle mass index (SMI), fat distribution, and metabolic markers. Participants are adults with stage I–III non‑metastatic breast cancer scheduled for surgery and adjuvant therapy. No experimental treatments are given; the study collects imaging and body composition data at multiple time points to map trends in muscle loss, fat redistribution, and related metabolic changes. The design aims to characterize natural recovery patterns to inform survivorship care.

Who should consider this trial

Good fit: Adults older than 18 with newly diagnosed stage I–III non‑metastatic breast cancer within 12 months who are scheduled for surgery and adjuvant therapy, who will remain locally available for follow‑up and are not planning pregnancy, are ideal candidates.

Not a fit: Patients with metastatic (stage IV) disease, those with incompatible implantable devices or joint replacements that prevent accurate body composition measurement, or those planning to relocate or become pregnant during the study are unlikely to benefit.

Why it matters

Potential benefit: If successful, the data could help identify patients at risk for sarcopenia or adverse fat redistribution and guide personalized rehabilitation and follow‑up care.

How similar studies have performed: Previous observational cohorts have documented post‑treatment muscle loss and changes in fat distribution in cancer survivors, so the general approach is established though local longitudinal data remain valuable.
