[HER2], estrogen receptor [ER], and progesterone receptor of breast cancer gene expression categorize tumors into
[PR]) further classifies tumors into subtypes. The profiles molecular subtypes of basal-like, normal-like luminal A,
luminal B, and HER2‑enriched tumors. Different breast
cancer subtypes have different MRI radiomic features
serving as prognostic indicators called PR+ versus PR‑,
ER+ versus ER‑, HER2+ versus HER2‑, and triple‑negative
tumors or cancers. All these respond differently to different
therapies and are used in DL.
In short, DL information from computer-extracted MRI-
visible soft-tissue tumor features with metabolite phenotypes
distinguish breast cancer subtypes by quantitative signatures
to predict prognosis for precision medicine.
