Background: Breast edema, characterized by fluid accumulation in breast tissue, is a common yet understudied complication following breast-conserving surgery (BCS) and radiotherapy for breast cancer. Its impact on physical and emotional well-being highlights the need for deeper exploration of its prevalence, risk factors, and clinical management.
Objectives: To evaluate the prevalence of breast edema following breast surgery, investigate its association with arm lymphedema, and explore links to surgical interventions.
Methods: We analyzed 105 breast cancer patients treated with BCS and axillary interventions, including sentinel lymph node biopsy (SLNB), lymph node sampling, or axillary lymph node dissection (ALND). Comprehensive evaluations included physical exams, arm circumference measurements, and a thorough review of patient demographics, medical history, and disease progression to assess the presence and severity of breast and arm lymphedema.
Results: Breast edema prevalence was 7.6%, with rates significantly influenced by surgical extent. None of the SLNB patients exhibited breast edema, compared to 23.5% of ALND patients. Significant predictors included arm lymphedema (OR 57.54, P = 0.024), body mass index (OR 0.65, P = 0.016), and tumor grade (OR 51.78, P = 0.040). Co-occurrence of breast and arm lymphedema was observed in 50% of cases.
Conclusions: Breast edema is a significant postoperative complication influenced by surgical extent and lymphatic disruption. Improved diagnostic methods, multidisciplinary care, and innovative surgical strategies are essential for mitigating this condition and enhancing patient outcomes.
