Abstract

This brief review discusses the diagnostic ability of prostate specific antigen adjusted for the transition zone volume (PSATZ) for the detection of prostate cancer in patients with intermediate prostate specific antigen (PSA) levels. PSATZ was defined as the quotient of the PSA value and the calculated transition zone volume. In comparison with standard parameters including PSA and prostate specific antigen density, PSATZ could be a useful indicator for the detection of prostate cancer in patients with PSA values between 4.1 and 10.0 ng/ml, especially in those with normal digital rectal examinations. Similar observations consistent with our results have been also reported by other investigators. PSATZ has some disadvantages including volumetry and expensive cost. Further study is necessary to discuss whether PSATZ is superior to other new modalities such as free-to-total PSA ratio with regard to diagnostic cost and efficacy.
