摘要

Background

Accurate characterization of the breast cancer-related lymphedema (BCLR) population is essential to understand its pathophysiology and develop predictive models for identifying at-risk patients and implementing tailored preventive microsurgical strategies. Key factors influencing BCRL severity and progression remain unclear. This study characterizes patients with BCRL seeking microsurgical treatment and evaluates the impact of oncological treatment intensity on lymphedema severity and progression.

Methods

This cohort study was conducted at an outpatient tertiary lymphedema clinic between 2017 and 2023. BCRL severity was assessed at intake by a lymphedema-specialized plastic surgeon using International Society of Lymphology staging and indocyanine green lymphography with near-infrared fluorescence imaging (ICG-NIFI). Data were collected during scheduled medical evaluations and analyzed retrospectively. Exploratory analysis investigated associations between oncological treatment intensity and BCRL severity and progression.

Results

A total of 163 consecutive female patients with BCRL were included. Lymphedema severity varied significantly, with no consistent link between severity and time since onset. A significant association was found between axillary lymph node dissection (ALND) and ICG-NIFI stages (p<0.001). However, no significant associations were found between oncological treatment intensity—surgery, radiotherapy, systemic treatment—and BCRL severity and progression. Analyses further revealed associations between lymphedema severity, body mass index, postmenopausal status, and clinical course.

Conclusion

This study provides a comprehensive profile of patients with BCRL seeking microsurgical treatment, revealing variable lymphedema progression patterns. Oncological treatment intensity did not appear to influence BCRL severity or progression, suggesting that these may depend more on biological predisposition. These findings enhance BCRL understanding and highlight the importance of precise patient characterization, laying the foundation for targeted, individually tailored preventive microsurgical interventions.
