Case studies of fulvestrant (‘Faslodex’) in postmenopausal women with advanced breast cancer

Fulvestrant is a new oestrogen receptor (ER) antagonist that is licensed for the treatment of postmenopausal women with advanced breast cancer progressing following antioestrogen treatment and may also be effective in those progressing after non-steroidal aromatase inhibitors. The use of fulvestrant in a Compassionate Use Programme (CUP) in a ‘real-life’ setting has permitted its activity and tolerability profile in patients with different disease characteristics to be observed. Here, we present five case reports of fulvestrant use in postmenopausal women with advanced breast cancer progressing after prior endocrine therapy. Clinical experience from the CUP supports the published clinical trial data and suggests that fulvestrant is a valuable new treatment for postmenopausal women with advanced breast cancer, including those with visceral metastases and human epidermal growth factor receptor 2-positive disease.
