Summary
Higher body mass index (BMI) increases the risk of breast cancer-related lymphedema (BCRL). Managing weight is crucial for breast cancer patients to improve outcomes and reduce BCRL incidence.
Area of Science:
- Oncology
- Clinical Epidemiology
Background:
- Breast cancer-related lymphedema (BCRL) is a significant concern affecting patient quality of life.
- Body Mass Index (BMI) is a common metric for assessing body weight and its potential health implications.
Purpose of the Study:
- To investigate the association between body mass index (BMI) and the incidence of breast cancer-related lymphedema (BCRL).
Main Methods:
- Retrospective cohort study of 1464 breast cancer patients.
- Patients categorized by BMI: <25, 25 to <30, and ≥30 kg/m².
- Adjusted for axillary lymph node dissection, infections, radiotherapy, and comorbidities.
Main Results:
- BCRL incidence was 23.4%.
- Higher BMI correlated with increased BCRL risk, with significant rates at 1, 2, and 3 years post-treatment.
- Multivariate analysis identified BMI as an independent risk factor for BCRL.
Conclusions:
- Elevated BMI is significantly associated with a higher risk of developing BCRL.
- Higher BMI negatively impacts BCRL-free survival.
- Weight management is a critical component of comprehensive breast cancer care.
