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...
Purpose: In this study we analyzed the changes of fPSA and f-PSA% and its prognostic significance in course of hormone treatment for metastatic prostate cancer. Materials and Methods: We retrospectively analyzed 75 patients with metastatic prostate cancer who received maximal androgen deprivation therapy...

The free-to-total psa-ratio: Critical aspectsJ. M. WolffG. StöckerH. BorchersH. HaubeckG. Jakse
(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...
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...
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...
Purpose The ratio between free and total prostate specific antigen (PSA) in serum improves the specificity of total serum PSA for the detection of prostate carcinoma in select populations. The value of the free-to-total PSA ratio for a P... Chris,H.,Bangma,... - 《Journal of Urology》 ...
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 ...
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
