Prostate-specific antigen density as a proxy for predicting prostate cancer severity: Is there any difference between systematic and targeted biopsy?

open access: yesSaudi Journal of Medicine and Medical Sciences, 2023
Background: Prostate cancer screening with prostate-specific antigen (PSA) can result in unnecessary biopsies and overdiagnosis. Alternately, PSA density (PSAD) calculation may help support biopsy decisions; however, evidence of its usefulness is not ...

Machine learning methods can more efficiently predict prostate cancer compared with prostate-specific antigen density and prostate-specific antigen velocity

open access: yesProstate International, 2019
Background: Prostate-specific antigen (PSA)–based screening for prostate cancer has been widely performed, but its accuracy is unsatisfactory. To improve accuracy, building an effective statistical model using machine learning methods (MLMs) is a ...

Identifying Prostate Cancer Among Men with Lower Urinary Tract Symptoms

open access: yesEuropean Urology Open Science, 2021
Background: In men aged above 50 yr, lower urinary tract symptoms (LUTS), benign prostate hyperplasia, and prostate cancer are common urological conditions. Current guidelines for general practitioners frequently recommend prostate-specific antigen (PSA)

Addition of Prostate Volume and Prostate-specific Antigen Density to Memorial Sloan Kettering Cancer Center Prostate Cancer Nomograms

open access: yesEuropean Urology Open Science, 2021
Prostate-specific antigen (PSA) density is an established prognostic marker for prostate cancer. We investigated whether the inclusion of PSA density or prostate volume in the Memorial Sloan Kettering Cancer Center nomograms improves the prediction of ...

CUT-OFF POINT OF PSA AND PSA DENSITY IN PROSTATE CANCER SUSPECTED PATIENTS

open access: yesJurnal Urologi Indonesia, 2016
Objective: In Hasan Sadikin General Hospital Bandung prostate biopsy is recommended for patients with prostate specific antigen (PSA) levels above 10 ng/mL or PSA density (PSAD) above 0.15 if PSA in between 4–10 ng/mL.

THE VALUE OF TRANSITIONAL ZONE PSA DENSITY IN THE DIAGNOSİS OF THE PROSTATIC CARCINOMA

open access: yesUrology Research and Practice, 2019
PSA is the most important tumor marker for the diagnosis of prostatic carcinoma. If 4.0 ng/ml, which is the widely accepted cut-off value, is used, 2/3 of the biopsies are negative.

Reliability of volume or age-adjusted prostate specific antigen to improve diagnostic accuracy

open access: yesThe International Journal of Biological Markers, 1995
Prostate Specific Antigen (PSA), PSA density, PSA excess, and PSA age-specific range have been compared in 331 subjects (35 cancers, 296 benign) with equivocal findings at screening by PSA or palpation + transrectal ultrasonography.

Performance of PSA and of PSA density in the diagnosis of prostate carcinoma

open access: yesActa Cirúrgica Brasileira, 2002
OBJECTIVE: The aim of the study was to investigate the influence of the prostate volume and PSA density on the performance of total PSA to diagnosis of prostate carcinoma. METHODS: We analyzed 217 patients (PSA 0-10ng/ml) submitted to transrectal sextant

Characterisation of an automated Dual Piston Pressure Swing Adsorption (DP-PSA) system [PDF]

open access: yes, 2013
The drive to fast Pressure Swing Adsorption (PSA) processes leads to the challenge of designing and analysing experiments that allow the testing of adsorbents under fast cycle conditions. Here we present the Dual Piston-Pressure Swing Adsorption (DP-PSA)

Evaluation of prostatic cancer prevalence in patients with prostatic-specific antigen between 4 and 10 and normal digital rectal examination

open access: yesAdvanced Biomedical Research, 2016
Background: Prostate cancer is one of the most common male cancers. The prevalence of prostate cancer is different due to genetic and environmental factors.
