title: [Does PSA density of the transition zone represent a useful parameter in the diagnosis of prostate carcinoma?].
abstract: Prostate specific antigen (PSA) has unequivocally proved its clinical usefulness ad a serum marker for prostate cancer. In order to enhance the specificity of serum PSA, several diagnostic parameters have been employed including PSA density of transition zone (TZ). The authors report their experience on the efficacy of PSA density TZ with level of PSA < 4 ng/ml, between 4-10 ng/ml, > 10 ng/ml, in the diagnostic of prostate cancer. The PSA density of TZ resulted uscless for PSA levels < 4 ng/ml, but improved the diagnostic specificity associated to PSA serum in the PSA levels ranging between 4-10 ng/ml and > 10 ng/ml.
