The Use of Prostate Specific Antigen and Prostate Specific Antigen Density in the Diagnosis of Prostate Cancer in a Community Based Urology Practice

Journal of Urology, 1994
Since 1989 we have used serum prostate specific antigen (PSA) levels as an indication for ultrasound guided systematic biopsies of the prostate. Realizing that the PSA level in part reflects prostatic glandular epithelial volume, we reviewed the accumulated data on our last 2,340 biopsies to determine if the quotient of PSA and prostatic volume ...

Racial Variations in the Performance of Prostate Specific Antigen and Prostate Specific Antigen Density in the Era of Extended Prostate Biopsy Schemes

Journal of Urology, 2008
The incidence of prostate cancer is known to vary as a function of race. To date few studies have evaluated the performance of the prostate specific antigen test and its indexes in unique racial populations. We examined the performance of prostate specific antigen, prostate specific antigen density and transition zone density in racial groups ...

Prospective Evaluation of Prostate Specific Antigen and Prostate Specific Antigen Density in the Detection of Nonpalpable and Stage T1C Carcinoma of the Prostate

The Journal of Urology, 1996
We evaluated prospectively prostate specific antigen (PSA) and prostate specific antigen density in the detection of prostate cancer in patients with normal findings on digital rectal examination with and without normal transrectal ultrasound.Consecutive patients (184) with an elevated serum PSA and normal digital rectal examination underwent ...

Comparison of Prostate Specific Antigen and Prostate Specific Antigen Density for Predicting the Degree of Gleason Score of Prostate Cancer

Journal of Analytical Oncology, 2015
Introduction: In this study we evaluate the relationship of PSA and PSAD with the degree of Gleason score of prostate cancer in transrectal ultrasound guided biopsy specimens. Methods: From March 2003 to October 2009, 1025 transractal ultrasound guided biopsies were performed in our hospital.

Is prostate-specific antigen density more useful than prostate-specific antigen levels in the diagnosis of prostate cancer?

Urology, 1995
To compare the performance of prostate-specific antigen (PSA) levels with the performance of PSA density (PSAD), the ratio of the serum to the size of the prostate, as predictors of the presence of prostate cancer.We analyzed the results of digital rectal examination (DRE), transrectal ultrasonography (TRUS), serum PSA levels, and PSAD in 244 patients ...

Value of the Free to Total Prostate Specific Antigen Ratio and Prostate Specific Antigen Density for Detecting Prostate Cancer in Japanese Patients

International Journal of Urology, 1998
Background: This study evaluated the free to total serum prostate specific antigen (f/t PSA) ratio and prostate specific antigen density (PSAD) in detecting prostate cancer in Japanese males with a PSA level between 2.5 and 20.0 ng/mL in a community‐based urology practice.

Prostate-specific antigen (PSA) density in the diagnostic algorithm of prostate cancer

Prostate Cancer and Prostatic Diseases, 2017
Screening for prostate cancer using prostate-specific antigen (PSA) alone leads to un-necessary biopsying and overdiagnosis. PSA density is easily accessible, but early evidence on its use for biopsy decisions was conflicting and use of PSA density is not commonly recommended in guidelines.We analyzed biopsy outcomes in 5291 men in the population-based

Prostate-specific antigen density — a reliable parameter for the detection of prostate cancer?

World Journal of Urology, 1996
We compared the prostate-specific antigen density (PSAD) in clinically and surgically staged patients with specimen-confined prostate cancer (n = 57) and in patients with benign hyperplasia (n = 69), who underwent transvesical adenomectomy. The PSAD was calculated from the preoperative PSA level and the specimen volume.

Prostate-Specific Antigen Density: A Means to Enhance Detection of Prostate Cancer

European Urology, 1994
The ability of serum prostate-specific antigen (PSA) and PSA density (PSAD) to distinguish patients with prostate cancer from those with benign diseases of the prostate was assessed in 495 men. All men were evaluated with PSA determination, digital rectal examination (DRE), transrectal ultrasonography (TRUS) and ultrasound-guided prostatic biopsies ...

Does Prostate-Specific Antigen Density Alter Decision Making on Biopsy?

European Urology, 1996
The 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
