“An experimental urine test that detects genetic changes associated with prostate cancer identified 92 percent of men with elevated PSA (prostate-specific antigen) levels who had high-grade cancers, according to a study published today in JAMA Oncology online.
“ ‘The test has the potential to be a significant improvement over PSA alone in distinguishing between low- and high-grade prostate cancer, especially in the PSA gray zone patient. It could reduce hundreds of thousands of invasive biopsies each year. Given the pain and risks associated with performing a prostate biopsy, that’s not a trivial thing,’ said first author James McKiernan, MD, the John K. Lattimer Professor and chair of urology at Columbia University Medical Center (CUMC) and urologist-in-chief at NewYork-Presbyterian/Columbia. In addition, the test is the only urine-based assay that does not require a digital rectal exam prior to collection and is easily integrated in the clinic environment.”
