Synopsis

Assessment of axillary lymph node metastasis burden before surgery in breast cancer patients is warranted for axillary management. This study developed a simple model based on the standard breast MRI features of breast tumor and axillary lymph node to differentiate patients with no, low or heavy axillary metastasis burden. With the help of this model, patients and clinicians would make more rational decision when to choose omitting surgery, sentinel lymph node biopsy or axillary lymph node dissection for axilla management.
