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...

Prostate Specific Antigen (PSA) Free with Total Ratio: This test is used to measure the percentage of free PSA relative to the total amount of PSA in men with serum PSA concentrations.

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 ...
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)在诊断早期前列腺癌(PCa)中的价值。
The percentage of f-PSA (f-PSA/t-PSA) was significantly lower in patients with PCa (median value: 9.5% in the IMMULITE test) compared to patients with BPH (21.2%) and healthy controls (23.7%). The receiver-operation-characteristics analyzis (ROC) shows, compared to t-PSA alone, ...
(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=0.34).Comparing with PSA,PSAD provides better sensitivity and specificity...
Objective To study the value of TPSA,fPSA and the ratio of fPSA/TPSA in differential diagnosis of prostate cancer(PCa). 目的观察血清总前列腺特异性抗原(TPSA)、游离前列腺特异性抗原(fPSA)及fPSA/TPSA比值在前列腺癌症鉴别诊断中的价值。3
Objective:To investigate the clinical value of serum total PAS and the ratio of free to total PSA(FT) in differential diagnosis benign prostate hyperplasia(BPH)and prostatic carcinoma(PCa).Methods:Serum FPSA and TPSA were measured in 137 patients with prostate carcimoma(PCa) and benign prostate ...
