OBJECTIVE To develop a formula that incorporates age, prostate volume, race, and prostate-specific antigen (PSA) level into a single score for prostate cancer detection. MATERIALS AND METHODS We developed a PSA-age volume (AV) score by multiplying the patient age by the prostate volume and dividing it by the PSA level. The PSA-AV was developed using 1000 prostate biopsy specimens and was validated on 318 internal and 4406 external biopsy specimens. RESULTS We analyzed 1000 biopsy specimens… CONTINUE READING
