Moreover, each CIC subtype tended to preferentially affect different categories of breast cancer, with TiT (P < 0.0001) and oCICs (P = 0.008) targeting luminal B (Her2+), TiM (P = 0.011) targeting HR− (Her2+/HR− and TNBC), and MiT targeting luminal A (P = 0.017) and luminal B (Her−) (P = 0.006). Here, ERBB2 is linked to breast carcinoma.
