ERBB2 and triple-negative breast carcinoma: Five criteria are suggested for categorizing tumors: estrogen receptor (ER) via IHC, progesterone receptor (PR) via IHC (all RNA-seq data), HER2 status via IHC (all RNA-seq data), intrinsic molecular subtypes determined by PAM50 (all RNA-seq data), triple-negative breast cancer (TNBC) identified through IHC (all RNA-seq data), and basal-like subtypes identified through PAM50.
