Prostate Specific Antigen Density Correlates With Features of Prostate Cancer Aggressiveness

Journal of Urology, 2007
An increased prostate specific antigen density (serum prostate specific antigen divided by prostate volume) is an established parameter to help determine the need to perform prostate biopsies. A man with a high prostate specific antigen and a normal size prostate gland is more likely to have cancer than a man with the same prostate specific antigen and

Prostate specific antigen density in patients with histologically proven prostate carcinoma

Cancer, 1994
Prostate specific antigen (PSA) does not appear to have the specificity to distinguish between benign prostate hyperplasia and cancer when the PSA is low. PSA density is thought by many to improve the specificity for cancer; however, this theory remains controversial.The authors retrospectively reviewed 220 carcinomas in radical prostatectomy specimens

PROSTATE-SPECIFIC ANTIGEN DENSITY

Urologic Clinics of North America, 1997
Nearly 20 years have passed since PSA was definitively identified. Throughout this period, its clinical application as a tumor marker has expanded significantly. Today, besides monitoring prostate cancer therapy, PSA is being used extensively in mass screening programs for early detection of adenocarcinoma of the prostate and has become the most ...

Comparison of Prostate Specific Antigen with Prostate Specific Antigen Density for 3 Clinical Applications

Journal of Urology, 1994
We compared prostate specific antigen (PSA) to PSA density for 3 clinical uses: detection of nonpalpable prostate cancer, staging of clinically localized prostate cancer and prediction of PSA detectability following radical prostatectomy. Of 153 men with normal digital rectal examinations undergoing prostate biopsy 25% had prostate cancer.

Complexed prostate-specific antigen, complexed prostate-specific antigen density of total and transition zone, complexed/total prostate-specific antigen ratio, free-to-total prostate-specific antigen ratio, density of total and transition zone prostate-specific antigen: results of the prospective multicenter European trial [PDF]

Urology, 2002
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.

Correlation of prostate-specific antigen and prostate-specific antigen density with outcome of prostate biopsy

Urology, 1994
We attempt to correlate prebiopsy serum prostate-specific antigen (PSA) concentration and prostate-specific antigen density (PSAD) with histologic results of prostate biopsy.Sixty-two consecutive patients underwent prostate biopsy because of elevated PSA greater than 4 ng/mL and/or abnormal findings on digital rectal examination (DRE).

Effect of finasteride on prostate-specific antigen density

Urology, 1994
Prostate-specific antigen density (PSAD) has been proposed as a diagnostic marker for prostate cancer. Because treatment with finasteride may affect PSAD differently in men with BPH compared with men with BPH plus prostate cancer, we evaluated the diagnostic utility of PSAD in men treated with finasteride for twelve months.Data for this analysis were ...

Serum Prostate Specific Antigen and Prostate Specific Antigen Density in Patients Receiving Radical Prostatectomy

International Journal of Urology, 1996
Objective: To study the significance of prostate specific antigen (PSA) and prostate specific antigen density (PSAD) for predicting the risk of occult metastatic disease and extra‐prostatic invasion of prostate cancer in patients receiving radical prostatectomy.Patients and methods: The cases of 41 consecutive patients who underwent radical ...

[Value of prostate-specific antigen density and transitional-zone prostate-specific antigen density in the diagnosis of prostate cancer].

Actas urologicas espanolas, 2003
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 ...

TRANSITION ZONE PROSTATE SPECIFIC ANTIGEN DENSITY

The Journal of Urology, 1998
Among the new approaches to enhance the performance of prostate specific antigen (PSA) testing in a biopsy population is the use of the free-to-total PSA as well as the transition zone density, which is calculated by dividing the PSA by the transition zone volume.
