Study provides new insight on how HER2-low tumors may evolve in breast cancer patients
The finding that breast tumors can evolve to express low HER2 potentially widens the number of patients who can benefit from new investigational agents, typically novel antibody-drug conjugate therapies, that are currently in clinical trials for HER2-low tumors.
The first study of its kind exploring how breast cancers change from the primary to the recurrent tumor has revealed that nearly 30% of breast cancer patients convert from, or to, human epidermal growth factor receptor (HER)2-low status. Specifically, the study found that 14% of triple-negative breast cancers with HER2-negative expression (also referred to as HER2-0) in the primary tumor converted to HER2-low expression in the recurrent tumor possibly offering an option to such hard-to-treat tumors.
