• Tumour SUVmax could be an imaging biomarker for predicting ALNM • Tumour SUVmax predicting ALNM is effective in ER-positive/HER2-negative and HER2-positive subtypes • Tumour SUVmax predicting ALNM is inaccurate in triple-negative subtypes • Accurate prognostic prediction based on molecular subtype may facilitate individualized management.

A high primary tumor SUVmax on 18F-FDG PET/CT was an independent factor associated with worse disease-free survival in patients with primary invasive ductal breast cancer.

The breast tumor strain ratio on ultrasound elastography is associated independently with axillary lymph node metastasis in patients with invasive breast cancer.

MR morphologic features, including lobular mass shape and smooth mass margin, were independently associated with breast cancer in young women, in addition to positive axillary nodal status and higher p53 expression status.
