Popis: Background Endocrine therapy is the preferred treatment in oestrogen- and/or progesterone-receptor (ER/PgR) positive breast cancer. Fulvestrant is a pure ER-antagonist. We present results from the Austrian Fulvestrant Registry. Methods Three-hundred and fifty patients were included. Time to progression (TTP) was defined as primary endpoint. A multivariate analysis was performed to identify factors significantly associated with TTP. Results Fulvestrant was administered as first-line therapy in 26%, second-line in 49%, and third-line or beyond in 25%. TTP was median 7 months. We observed a response in 15% of patients and 41% had SD ≥ 6 months. First-line treatment and non-visceral metastases were associated with longer TTP. One case of pulmonary embolism was reported. Grade 3 toxicities consisted of joint pain (1.4%), nausea (1.4%) and hot flashes (0.3%). Conclusions Fulvestrant was effective and well tolerated. TTP was superior to other trials, due to the large proportion of first-line patients. Activity is apparently independent of Her2-status.
