Our recent paper reviewed studies that report the use of urine-based biosensors to detect prostate cancer in patients. We identified 76 such articles and discussed 14 in the review which studied urine samples from prostate cancer patients. These studies detect prostate cancer through sensing biochemical, protein, or nucleic acid levels in urine samples. The studies reported several promising approaches but typically had small sample sizes and were poorly designed to assess the utility of such tests in a population setting. Each class of detection has unique strengths which may be useful in addressing this clinical problem. The tests also have weaknesses that must be assessed in the context of the well-established tests which are already available. Furthermore, whether such devices can discriminate between aggressive and indolent cancer has not yet been addressed and will entail optimized multiplexed biomarker panels and long-term clinical trials.
