前列腺癌根治术后PSA 持续通常定义为 PSA > 0.1 ng/ml；PSA 持续存在与不良病理学特征强烈独立相关。PSA 持续的患者生存预后较差；根据病理特征、PSA 水平/动力及基因风险分层模型可能有助于治疗的个性化；分子成像的作用仍然被低估。原文阅读：EAU 2024: Is All PSA Persistence Created Equal? Definition and Dia...
Diagnostic utility of total PSA, free PSA and PSA density at total PSA levels below 4 ng/ml compared to total PSA levels between 4.1 and 10.0 ng/ml in an early prostate cancer detection program - ResearchGatedoi:10.1016/S1569-9056(03)80514-6A. Berger...
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=...
Objective To explore the clinical value of determination of the total prostate-associated antigen(TPSA),free prostate-associated antigen(FPSA),FPSA/TPSA ratio and ferritin alone and jointly for prostate cancer. Methods The concentration of TPSA,FPSA,ferritin and FPSA / TPSA were detected in 94 ...
.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 (90.9% and 92.7%).Conclusion:PSAD can provide useful information in differentiating PCa and BPH.But no diagnostic value of F...
We herein provide an overview on the contemporary diagnostic and therapeutic strategies for prostate cancer, with emphasis on the role of prostate PSA. We also discuss the therapeutic options for localized disease. 展开 被引量: 9 年份: 2005 ...

临床上 PSA 相关指标如下: 总 PSA(t PSA,total PSA):即血液中游离态 PSA 和复 合态 PSA 的总和.1986 年,Hybritech 公司在对一组无前列腺 癌男性进行研究后,首次提出了传统的临界值 4.0 μg/L[5].这是 FDA 批准的第一次 PSA 试验[6].因此,确定 PSA 值 > 4.0 μg/L 用于推荐活检,尽管已知男性...
