    Axillary reverse mapping (ARM) aims to preserve upper limb lymphatic drainage during breast cancer surgery to reduce lymphedema risk.

  • 2

    A study analyzed 142 breast cancer patients to identify independent predictors of metastasis in ARM lymph nodes.

  • 3

    Metastasis was found in 23.24% of ARM lymph nodes, with several independent predictors identified through multivariate analysis.

  • 4

    A preoperative nomogram was developed, demonstrating excellent discrimination in predicting ARM lymph node metastasis risk.

  • 5

    The nomogram incorporates factors like menarche age, inflammatory markers, imaging, and ARM anatomy for risk assessment.
