We can confirm that regarding local recurrence in our cohort, Luminal-A-like and Luminal-B-like (HER2 negative) tumors were at a low risk, while HER2-positve/non- luminal and triple-negative breast cancer were at increased risk [50] of local recurrence as also a higher cumulative incidence of time to distant metastasis [46]. Here, ERBB2 is linked to triple-negative breast carcinoma.
