Search for effective antiestrogens, based on estradiol, led to the synthesis of the agent – ICI-182780 (fulvestrant). Fulvestrant is an estrogen receptor antagonist, which interrupts dimerization and translocation of the ER (estrogen receptors), blocks the binding of the cofactor and two activation centers. The complex of Fulvestrant and the ER is rapidly degraded, resulting in decrease or complete disappearance of the estrogen receptors, the transduction of the signals through the ER stops accordingly. In practice this drug (Fulvestrant) can be used in any line of endocrine therapy in postmenopausal patients, suffering advanced breast cancer with the high expression of the estrogen and progesterone receptors. But for the maximum effect it is very important to start the Fulvestrant treatment much earlier. It is determined that the effective dosage of Fulvestrant for clinical practice is 250 mg intramuscularly every 28 days.
This paper outlines the experience of the Fulvestrant administration in the City Clinical Hospital No.57 in patients with regional and disseminated breast cancer with visceral metastases since 2008 in Moscow.
Key words: fulvestrant, disseminated breast cancer, endocrine therapy.
