Focused ultrasound increases drug delivery to liver tumours

A heat-sensitive liposomal preparation loaded with doxorubicin (multiple brands) was able to deliver its contents directly to liver lesions when the temperature was raised above 39.5 °C by focused ultrasound (FUS), according to a report from researchers at the University of Oxford, United Kingdom. Delivery of doxorubicin to the liver tumors was increased about fourfold by using FUS, and the treatment yielded a response in some patients.
