DFS according to BC Subtypes and LVI status. Cases with negative LVI had a significantly higher DFS rate compared with those with positive LVI in the (A) Luminal A and (B) Luminal B type cases. There were significant differences in DFS between the LVI-positive and -negative status in the (C) triple negative subtypes, but there was no difference in the (D) HER2-enriched and (E) Luminal/HER2 subtypes. DFS, disease-free survival; BC, breast cancer; LVI, lymphovascular invasion; HER2, receptor tyrosine-protein kinase erbB-2.
