Preparing for clincial trials of synchrotron microbeam radiation therapy for cancer treatment
Microbeam radiation therapy (MRT), using X-rays generated by a synchrotron facility, is a novel, preclinical form of radiotherapy that shows promise of providing a major advance in cancer control if successfully translated to clinical practice. Given that up to 50% of cancer patients receive radiotherapy, and that radiotherapy and surgery remain the major treatment modalities that achieve loco-regional control of cancer, the significance of developing MRT as a new treatment paradigm cannot be understated. In particular, the apparent tolerance of normal tissues to MRT-induced radiotoxicity holds promise of a greatly improved therapeutic index with this treatment modality, opening the way to significantly improved patient outcomes.
These studies will….
The major outcomes of this project will be generation of acute and long-term normal tissue radiation toxicity data using large animal models and development of accurate patient positioning, image guidance and MRT treatment planning systems. We will also continue studies using tumour models to better establish the conditions under which MRT provides optimal anti-tumour effects.
