Abstract

AIM: To develop a new optical device (prostate optical device, POD) for assessment of prostate tissue stiffness and evaluate its sensitivity and specificity in prostate cancer detection.PATIENTS AND METHODS: POD was tested in prostate phantoms and in patients with indications for prostate biopsy. Its sensitivity and specificity were compared to digital rectal examination (DRE) and transrectal ultrasonography (TRUS).RESULTS: POD was able to identify stiffness differences on each prostate phantom. 45 patients were included in the study. Sensitivity of TRUS (40%) was significantly lower to POD (85.7%) and DRE (74.3%) (p = 0.000 and p = 0.003, respectively). There was no statistical difference between POD and DRE (p = 0.221). The combination of POD and DRE showed the highest sensitivity (88.6%), positive predictive value (81.6%), and negative predictive value (42.9%) among all diagnostic tests.CONCLUSIONS: POD identified prostatic stiffness differences with the same sensitivity of DRE performed by an experienced urologist providing an objective indication for prostate biopsy and early prostate cancer detection.
