New prostate cancer test could diagnose five years earlier

Researchers at the University of East Anglia and the Norfolk and Norwich University Hospital have developed a urine test, dubbed PUR (Prostate Urine Risk), to diagnose aggressive prostate cancer and predict whether patients will require treatment up to five years earlier than standard clinical methods. The revolutionary test also identifies men who are up to eight times less likely to need treatment within five years of diagnosis. The University says that it hopes the breakthrough “could help large numbers of men avoid an unnecessary initial biopsy and repeated invasive follow-ups for 'low risk' patients on active surveillance.” Previous urine biomarker tests have been designed specifically for single purposes such as the detection of prostate cancer on re-biopsy (PCA3 test). But, this new test uses four PUR signatures to provide a simultaneous assessment of non-cancerous tissue and risk groups (low, intermediate and high-risk) to show how aggressive the cancer is. ...
