Key clinical point: Human epidermal growth factor receptor 2 (HER2)-low vs HER2-0 expression was associated with improved breast cancer-specific survival (BCSS) outcomes in patients with early-stage triple-negative breast cancer (TNBC), particularly in the high-risk subgroups.
Major finding: Patients with HER2-low vs HER2-0 BC had significantly better BCSS rates in the overall population (96.6% vs 93.7%; log-rank P = .027) and in high-risk subpopulations comprising patients without a pathological complete response despite neoadjuvant chemotherapy (log-rank P = .047) or those with stage-III BC (log-rank P = .010).
Study details: Findings are from a study including 1445 female patients with early-stage TNBC, of whom 51.7% and 48.3% showed HER2-0 and HER2-low status, respectively.
Disclosures: This study was sponsored by the Health Commission of Henan Province, China. The authors declared no conflicts of interest.
