5-ALA is FDA approved in the USA as an optical imaging agent to be used during surgery for high grade gliomas. It allows the surgeon to better tell the difference between tumor and normal brain.. This study shows that it is safe and useful even in the elderly and for both attempts at complete resection as well as for biopsies. It has been used as standard of care in Europe for a decade before it was approved here in the USA a few years ago!
