In future, newly identified biomarkers could be used alongside imaging techniques for the non-invasive diagnosis of patients with advanced prostate cancer. A research team from the Medical University of Vienna and the Ludwig Boltzmann Institute Applied Diagnostics developed epigenetic biomarkers for the detection of circulating tumor DNA in plasma samples of patients. In this way, patients who fail to respond to treatment or suffer a relapse can be identified early thanks to non-invasive examination methods and consequently receive the optimal treatment. The study was published in the journal Molecular Cancer.
