Summary
Brief summary (as posted)
This observational cohort study aims to track longitudinal changes in body composition, including skeletal muscle mass and fat distribution, in patients diagnosed with breast cancer. Following primary surgery and adjuvant therapy, participants will be monitored over a 2-year period. The primary objective is to evaluate the natural progression of skeletal muscle mass index (SMI) and metabolic changes in this population. By conducting serial measurements, this study seeks to characterize the longitudinal trends in muscle loss and body composition shifts post-treatment, providing data to better understand the physiological impact of the cancer recovery process.

Arms (1)
- label
- Breast Cancer Post-Surgical Cohort
- description
- Patients with histologically confirmed Stage I-III non-metastatic breast cancer who have undergone primary surgery and are scheduled to undergo or have completed adjuvant therapy (chemotherapy and/or radiotherapy).
Primary outcomes (1)
- measure
- Change in Skeletal Muscle Mass Index (SMI)
- timeFrame
- Baseline, within 2 weeks after final chemotherapy cycle, within 2 weeks after final radiotherapy session, and 6 months following surgery.
- description
- Skeletal Muscle Mass Index (SMI) is the primary metric for assessing muscle mass. It is a composite value calculated by dividing total skeletal muscle mass (kg), as measured by multifrequency bioelectrical impedance analysis (ACCUNIQ BC720; SELVAS Healthcare), by the square of the participant's height (m2). Weight and height are measured at each time point to calculate this single aggregated value (kg/m2). Higher scores indicate greater muscle mass relative to height (better outcome).Unit of Measure: kg/m2
Secondary outcomes (10)
- measure
- Functional Battery: Change from Baseline in Handgrip Strength
