A number of potent and selective non-steroidal aromatase inhibitors are now available for treatment of advanced breast cancer in postmenopausal women, of which anastrozole and letrozole, in particular, represent a significant advantage over the earlier agents in terms of both efficacy and tolerability. These agents are rapidly becoming established as the second-line therapy of choice in postmenopausal women with advanced disease, progressing on tamoxifen, and data on their efficacy as first-line treatment compared with tamoxifen will be available in the near future. Exemestane, a new, steroidal aromatase inhibitor which potentially lacks cross-resistance with non-steroidal agents is still in clinical development. The full potential of the new-generation aromatase inhibitors in the treatment of breast cancer is currently being investigated in a large program of clinical trials evaluating their use as adjuvant treatment following surgery in postmenopausal patients with early disease.

Metastatic Setting

Breast cancer is a classical hormone-dependent tumour; therefore, endocrine therapy is the mainstay of treatment for hormone receptor-positive, human epidermal growth factor 2-negative advanced breast cancer. Until recently, classical endocrine agents such as tamoxifen, steroidal and nonsteroidal aromatase inhibitors and fulvestrant have been widely used in postmenopausal patients to treat locally advanced or metastatic disease. However, for patients with this subtype of breast cancer, the landscape of endocrine therapy is rapidly changing. Therapies targeting oestrogen modulation have evolved in recent years following the introduction of targeted agents, mTOR and CDK 4/6 inhibitors that are administered in combination with hormone therapy. As a result, options for endocrine therapy have expanded in recent years, and a variety of single-agent or combinations of targeted drugs and endocrine therapies are accepted. Fulvestrant is a selective oestrogen receptor downregulator (SERD) which was introduced to clinical practice in 2002, initially with the indication to treat postmenopausal women with hormone-receptor-positive advanced breast cancer as second-line therapy postdisease progression after aromatase inhibitors or tamoxifen. Additionally, fulvestrant has also been shown to be active in patients previously untreated with endocrine therapy, either both in the neoadjuvant and the metastatic setting, alone or in combination with other targeted therapies. Currently, the standard dose is 500 mg, which is administered with a loading dose. Fulvestrant received a new FDA indication in December 2016, in combination with palbociclib, both in pre/peri/postmenopausal women with breast cancer progressing after endocrine therapy. This manuscript aims to give an overview of new efficacy data and the current role of fulvestrant in the systemic therapy of hormone-receptor-positive advanced breast cancer, in the context of other available therapeutic modalities.
