Fulvestrant (Faslodex) is an oestrogen receptor (ER) antagonist with demonstrated efficacy in patients with advanced and pretreated breast cancer.


We present a single-centre experience with fulvestrant administered under the compassionate use programme (CUP) to a total of 54 postmenopausal women with metastatic breast cancer progressing on multiple endocrine and cytotoxic therapies. Patients received 250 mg fulvestrant i.m. once monthly as second- (n = 8), third- (n = 30), fourth- (n = 14) and fifth-line (n = 2) hormonal treatment. The median number of previous endocrine therapies was 2 (range 1-4). Most of the patients also had multiple palliative chemotherapies with a median of 1.7 (range 0-6) prior therapies. The median duration of fulvestrant treatment was 6.3 months (range 1-39 months) and the median duration of follow-up was 19.4 months (range 1-63 months).


Objective response was achieved by five patients (9.3%): one complete remission (CR) (1.9%) and four partial remissions (PR) (7.4%). Stable disease (SD) lasting > or =6 months was achieved by 16 patients (29.6%). Thus in all, fulvestrant conferred clinical benefit (CB) on 21 women (38.9%). The median time to progression (TTP) was 6.4 months. In all patients with CR and PR, tumour cells were positive for both ER and progesterone receptor (PgR), but lacked HER2/neu overexpression; one patient with PR had an unknown HER2/neu status. Overall, the drug was well tolerated. No grade 3/4 toxicities were reported.


Fulvestrant appears to be an efficient and well-tolerated drug even in women with advanced breast cancer progressing after multiple endocrine and/or cytotoxic treatments.
