A US Registry-Based Assessment of Use and Impact of Chemotherapy in Stage I HER2-Positive Breast Cancer.

Conclusions: Our data support the use of ACT for HER2-positive, node-negative T1b and T1c breast cancer, whereas no benefit was observed for ACT in T1mi and T1a HER2-positive, node-negative breast cancer. Although use of ACT is increasing in node-negative, HER2-positive breast cancer <2 cm, our findings caution against its use in the smallest of these tumors (T1mi and T1a) due to lack of survival benefit.
