ReviewEmerging Utility of Urinary Cell-free Nucleic Acid Biomarkers for Prostate, Bladder, and Renal Cancers.
By 2020 the estimated incidence of genitourinary (GU) cancers (prostate, bladder, and kidney) will be over 2 million worldwide and responsible for ∼800 000 deaths. Current diagnosis and monitoring methods of GU cancer patients are often invasive and/or lack sensitivity and specificity. Given the utility of blood-based cell-free nucleic acid (cfNA) biomarkers, the development of urinary cfNA biomarkers may improve the sensitivity of urine assays utilizing urine sediment for GU cancers. This review of urinary cfNA in GU cancers identifies the current stage of research, potential clinical utility, and the next steps needed to enter clinical use. ⋯ In this review, we evaluated the current status of urinary cell-free nucleic acid in genitourinary cancers. We identified the potential advantages of urinary cell-free nucleic acid over blood and urine sediment and its clinical use in genitourinary cancer.
