Diagnostic tests that target the presence of oestrogen receptor (ER) expression or activity are used to deter-mine a patient’s eligibility for endocrine therapies.

It is appropriate to test in situ, invasive, or recurrent breast cancer for ER expression or activity to select patients for preventative, adjuvant, or palliative endocrine therapies.

Current tests accurately exclude eligibility for endocrine therapies, but have only modest positive predictive value.

Novel multiplex molecular assays have demonstrated considerable potential to further refine the selection of patients for endocrine therapies.

Future tests could discriminate between different clinical treatment options.
