“…An exception is the Prostate Cancer Antigen 3 (PCA3) test, which may lead to improved early detection and help to avoid unnecessary biopsy. 8 PCA3 has been compared against F:T PSA and found to be similar in sensitivity and specificity with a cut-off value of 20 for PCA3 and 25% for F:T PSA. Further evaluation of these two tests, using them as criteria in risk stratification also showed a similar performance.…”

Email: surayne.segaran@fhft.nhs.uk Abstract Objective: The purpose of this study was to determine the ability of the ratio of free to total prostate-specific antigen and prostate-specific antigen density to predict the presence of clinically significant prostate cancer on template biopsies. The value of these tests may be underestimated as they were previously validated against sextant transrectal biopsy of the prostate, which has been proved to miss a large proportion of significant prostate cancers. The ability of these tests to specifically detect clinically significant cancers has not previously been studied. Patients and methods: A retrospective analysis was performed of patients undergoing transperineal template biopsy who also had free to total prostate-specific antigen and prostate-specific antigen density. Receiver-operating characteristic analysis was performed to determine the comparative utility of each test in the detection of all cancers as well as clinically significant cancers, by means of the area under the curve. Results: Data from 293 patients were analysed. Prostate cancer was detected in 72% of patients, of which 62% of this group had clinically significant disease. Receiver-operating characteristic analysis demonstrated the superiority of prostate-specific antigen density and free to total prostate-specific antigen over standard prostate-specific antigen in the overall detection of cancer (area under the curve 0.662 and 0.674 vs 0.534, p=0.003 and 0.02 respectively). Both tests were even more effective in the detection of clinically significant cancers (area under the curve 0.755 and 0.715 vs 0.572, p<0.0001 and 0.009 respectively). Conclusion: The free to total prostate-specific antigen and prostate-specific antigen density both appear to perform well at detecti...
