Total PSA, free and complexed PSA were measured, and the free/total (f/t) PSA and complexed/total (c/t) PSA ratios calculated, prior to catheterisation and at 48 and 72 h post-catheterisation in 39 men with acute retention. Subsequent histology showed 12 patients had prostate cancer and ...
To ascertain when the serum determination of the free prostate-specific antigen (PSA)/total PSA (fPSA/tPSA) ratio is clinically useful, and whether the identification of PSA or prostate-specific membrane antigen (PSM) mRNA in circulating cells has diagnostic advantages over the determination of ...
To evaluate the usefulness of measuring the free/total prostate-specific antigen (PSA) ratio (%fPSA) in men with initial PSA levels of 4.1 to 10.0 ng/mL as a predictor of the future risk of developing prostate cancer. Between 1989 and 2001, 201 subjects with an initial PSA level of 4.1...
To evaluate the value of free PSA/total PSA ratio (fPSA/tPSA) to boost total PSA (tPSA) specificity in the diagnosis of prostate cancer in a series of symptomatic patients.Prospective study on 334 patients presenting symptoms compatible with PBH and tPSA (ProStatus, Wallace Oy, Turku, Finla...

Ratio of Free-PSA/Total-PSA: An Indicator for Differentation between Patients with Prostate Cancer and Benign Prostatic HyperplasiaA survey on literature data concerning free prostate specific antigen and the corresponding cut-offs for f-PSA/t-PSA differentiating patients suffering from prostate ...
游离PSA/总PSA比值(f/tPSA) 1. Objective To study the early diagnostic value of prostate-specific antigen(PSA),density of PSA(PSAD),free/total prostate-specific antigen ratio(f/tPSA) for prostate cancer. 目的探讨前列腺特异性抗原(PSA)、PSA密度(PSAD)、游离PSA/总PSA比值(f/tPSA)在诊断早期前...
Results PSA,PSAD of PCa were significantly higher than that of BPH (PSA:46.3±33.8μg/Lvs7.04±6.91 μg/L,P=0.000021;PSAD:1.43±1.21μg.L-1.ml-1vs0.14±0.15ng.ml-1.ml-1,P=0.000055).There's no difference of F/TPSA ratio between BPH and PCa cases (0.22±0.18vs 0.18±0.11,P=...

PSA PSA, Free % Free PSA Prostate specific antigen (PSA) is produced exclusively by cells of the prostate gland. Used in conjunction with the digital rectal examination, PSA is a useful screening test for benign prostate hyperplasia (BPH) and prostate cancer development. ...
