    About the Special Issue

    The majority of breast cancers are estrogen receptor alpha (ERa) positive and most will initially respond to endocrine therapy. Current therapies to treat ERa-positive disease include aromatase inhibitors, selective estrogen receptor modulators (SERMs) and selective estrogen down-regulators (SERDs). However, resistance to these treatments will develop in many cancers and can be present either at the outset (de novo resistance) or develop on treatment (acquired resistance). Experimental and clinical investigations have demonstrated multiple mechanisms that can give rise to resistance and a range of therapeutic agents such as CDK4/6 inhibitors and other signalling inhibitors have been developed to circumvent these. Resistance mechanisms include changes in ER status (e.g. loss and mutation) and the involvement of compensatory pathways bypassing the dependence on estrogen activation particularly growth factor activation.

    In this issue, we welcome Reviews and Original Articles encompassing experimental laboratory research studies of endocrine resistance through to clinical investigations in breast cancer.
