Longitudinal Changes in Body Composition and Fluid Distribution During Chemotherapy in Breast Cancer Patients: A...

Area of Science:

• Oncology
• Body Composition Analysis
• Medical Diagnostics

Background:

• Breast cancer chemotherapy often involves anthracyclines and taxanes.
• Effects on body composition and fluid balance require precise assessment.
• Conventional methods may not differentiate tissue changes from fluid shifts.

Purpose of the Study:

• Evaluate longitudinal changes in body composition and fluid distribution during chemotherapy using bioelectrical impedance spectroscopy.
• Assess the impact of anthracycline and docetaxel on these changes.
• Identify patterns indicative of masked sarcopenia.

Main Methods:

• Prospective, longitudinal observational study.
• 51 female breast cancer patients undergoing systemic chemotherapy.
• Multifrequency bioelectrical impedance spectroscopy (BCM) used at baseline, 3, and 6 months.

Main Results:

• Significant fluid redistribution: increased extracellular water (ECW), decreased intracellular water (ICW), and elevated E/I ratio.
• Lean tissue mass (LTM) declined significantly, while adipose tissue mass (ATM) increased.
• Fluid accumulation observed, with anthracyclines linked to LTM loss and docetaxel to fluid/volume increases, suggesting masked sarcopenia.

Conclusions:

• Chemotherapy induces concurrent muscle loss and fluid redistribution in breast cancer patients.
• Bioelectrical impedance spectroscopy offers superior assessment of body composition compared to conventional methods.
• Early detection of these changes can guide nutritional and fluid management strategies.
