Our analyses suggest that 14% of ER+/Her2- patients may be HRD and therefore potentially eligible for treatments with HRD-directed therapies such as platinum agents and PARP inhibitors. As the ER+/Her2- subtype is the most common breast cancer subtype, this group of HRD patients is likely more sizable than that of HRD TNBC patients.
