Higher HER2-HQE is associated with increased RCB. Quantifying HER2 heterogeneity via HQE and percentage of HER2 IHC 3+ may help optimize therapeutic strategies in clinical practice.
Approximately 40 % of young women with luminal HER2-negative breast cancers have HER2-low or ultralow disease. These findings highlight the importance of accurately assessing HER2 expression in YWBC to identify candidates for emerging HER2-targeted therapies such as trastuzumab deruxtecan.
