Promising new therapy for inoperable brain cancers
Magnetic nanoparticle could be used in combination with radiation treatment and heat therapy to kill cancer cells
Australian scientists have made progress on a potential new approach that could be used to treat some of the most deadly brain cancers.
A new magnetic nanoparticle could be used in combination with radiation treatment and heat therapy to kill cancer cells, according to new research from the University of Wollongong and ANSTO.
The lead researchers from UOW and its clinical partners collaborated with ANSTO’s Australian Centre for Neutron Scattering to study the magnetic properties of the nanoparticles.
Abstract
Brachytherapy is an advanced technique of cancer treatment, where a high dose rate radioactive source, typically
192Ir, is inserted within a tumour volume to destroy the spread of cancerous cells. The complexity of such advanced treatment options requires accurate quality assurance (QA) tools to verify the treatment plan and track the High Dose Rate (HDR) source position as clinically prescribed. The misplacement of a HDR
192Ir brachytherapy source by several millimetres within a treatment volume is not clinically tolerated, and must be addressed prior to conducting the actual treatment. For the safety of patients benefiting from this treatment, it is ideal if the planned position of the HDR
