  Systemic hormone therapy of breast cancer often suffers from severe side effects mainly due to non-specific drug delivery. To overcome this limitation, we propose an effective strategy based on the association of the selective estrogen receptor down-regulator RU-58668 (RU) that acts as a pure hormone antagonist, with magnetic-fluidloaded liposomes (MFLs) which can be driven selectively into the tumors by a magnetic field gradient. MFLs consisted in 200-nm unilamellar phospholipid vesicles entrapping superparamagnetic iron oxide nanocrystals, fluorescently labeled and coated by poly(ethylene glycol) (PEG) chains ensuring long plasmatic half-life. Significant antitumoral activity of antiestrogen at doses usually sub-therapeutic was demonstrated against MCF-7 tumors xenografts in nude mice after weekly intravenous administration of RU-loaded MFLs followed by 4-hour exposure to an ..
