This prospective, multicenter European Prostate Cancer Detection study evaluated the value and performance of the molecular forms of prostate-specific antigen (PSA) and their derivatives in combination with prostate gland and transition zone volumes in early detection of prostate cancer in patients with PSA levels between 4 and 10 ng/mL.

To compare serum prostate-specific antigen (PSA) levels and PSA density (PSAD) among African American (AA), white, and Hispanic men with prostate cancer (PC) seen in an urban, equal-access urology clinic. Between January 1988 and January 1993, 1,105 men were screened for PC at Cook County Hospital in Chicago, Illinois.

The results of 225 systematic prostate biopsies from 1992 to 1993 were evaluated retrospectively. The parameters prostate-specific antigen (PSA) density and age-specific PSA values were compared with digital rectal examination, transrectal ultrasound, and PSA as single parameters and possible combinations.

With serum prostate specific antigen (PSA) levels of 4.1 to 10 ng/ml a significant number of patients are unnecessary subjected to biopsy. We try to determine if the calculation of prostate specific antigen density (PSAD) and prostate specific antigen density of the transition zone (PSADTZ) improve the capacity to discriminate between non-malignant ...

Prostate specific antigen, prostate specific antigen density and transition zone density have been previously identified as prostate cancer detection tools. Recent studies suggest that prostate specific antigen may be increasingly accurate for detecting clinically significant high grade prostate cancer (Gleason grade 7 or greater).

Does Prostate-Specific Antigen Density Alter Decision Making on Biopsy?
European Urology, 1996The ability of prostate-specific antigen density (PSAD) to predict prostate cancer in biopsy specimens is evaluated in patients with benign digital rectal examination (DRE) and prostate-specific antigen (PSA) between 4.0 and 10.0 ng/ml.144 referred patients with a benign DRE and PSA > 4.0 ng/ml were additionally evaluated by transrectal ultrasonography

Prostate-specific antigen (PSA) is the most accurate serum marker for cancer of the prostate (CaP). However, its sensitivity and specificity are suboptimal, especially at values ranging between 4.1 and 10.0 ng/ml (monoclonal), because benign prostatic hypertrophy and hyperplasia (BPH) and CaP frequently coexist in this range.

Prostate specific antigen (PSA) is useful as a tumor marker for monitoring patients with prostate cancer after definitive therapy. Limitations have been noted when PSA was used for the early detection of prostate cancer. The use of prostate specific antigen density [PSAD = PSA (ng/ml)/prostate volume (cc)] has been suggested to differentiate benign ...

We evaluated prospectively the ethnic variations in prostate specific antigen (PSA) and prostate specific antigen density in the detection of carcinoma of the prostate.A total of 297 consecutive patients with an elevated serum PSA and/or abnormal digital rectal examination underwent transrectal ultrasound with lesion directed and systematic biopsy (6 ...

The possibility of distinguishing prostate cancer from BPH with the prostate specific antigen (PSA) determination is particularly poor when PSA levels are between 4.1 and 10 ng/ml. In these cases the quotient of serum PSA and prostate volume, defined as prostate specific antigen density (PSAD), seems to enhance the accuracy of PSA alone. In this study
