Scientists have designed a blood test that reads genetic changes like a barcode – and can pick out aggressive prostate cancers by their particular pattern of gene activity. A team at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust found reading the pattern of genes switched on and off in blood cells could accurately detect which advanced prostate cancers had the worst survival. And the researchers believe the blood test could eventually be used alongside the existing PSA test at diagnosis to select patients who need immediate treatment.
