Researchers Develop New Blood Test For Prostate Cancer Detection
shutterstock_187967735A team of international researchers has identified a method that can detect cell-free tumor DNA in a patient’s bloodstream. The study, done in collaboration with Vanderbilt University researchers, may improve the way cancer is diagnosed allowing simultaneous predictions of treatment outcomes and monitoring of patient’s responses to therapy. In the study, published in the journal Clinical Chemistry, the research team analyzed a large array of blood samples using a novel method called liquid biopsy, and showed the capacity of this technique to correctly distinguish between prostate cancer cells and healthy cells. Moreover, this method allowed a three times higher sensitivity when compared to standard prostate-specific antigen (PSA) screening. "Based on the reported data and work in progress, I believe the 'liquid biopsy' will revolutionize cancer diagnostics, not only before a patient begins therapy but also following patient responses to therapy," study author William Mitchell, M.D., Ph.D., professor of Pathology, Microbiology and Immunology, said in a news release. The authors gathered serum samples (including PSA levels and tissue biopsy) from more than 200 p
