Fluorescent marker to fight tumours
SURVIVAL rates for one of the deadliest forms of brain tumour could be improved by using fluorescent marker.
Scientists found that by using a chemical to highlight cancerous cells they were able to identify the most aggressive types of disease without harming healthy brain-tissue.
The study, presented at the National Cancer Research Institute conference, involved 99 patients with suspected glioma, the most common form of brain cancer, which killed Dame Tessa Jowell, the former Labour cabinet minister, and is diagnosed in more than 2,200 cases each year in England.
The markers, which use a compound called 5-aminolevulinic acid, which glows pink when a light is shone on it, were able to detect the fastest growing tumours and to improve the accuracy of subsequent surgery.
