TL;DRAbstract
The PSA revolution that occurred over the previous 2 decades has positively impacted the detection of prostate cancer. Percent free PSA improves specificity, at the beginning the percent free PSA was used only in the gray zone 4-10 ng/ml. Analyzing our data, we confirm that the usefulness of percent free PSA in prostate cancer diagnosis increases, enlarging the reflex range. Our best result is obtained in the reflex range 2-10 ng/ml using a percent free PSA cut-off of 22%.
