Flu­o­res­cent marker to fight tu­mours

The Sunday Telegraph - - News - By Laura Don­nelly HEALTH ED­I­TOR

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.
