Age > 70 years, PV < 42 ml, PSA >26 ng/ml and 5 points of PI-RADS obtained same points (3 points), which doesn’t mean that those indicators had same ability in solely predicting PCa, but it means that age, PV, PSA or PI-RADS can provide same reference value to each other in predicting PCa. This evidence concerns the gene KLK3 and posterior cortical atrophy.
