可用于前列腺的早期诊断、筛查及疗效监测。 2、TPSA升高多提示为前列腺癌,但在某些前列腺炎、前列腺良性增生或前列腺创伤等时亦可升高; 3.、同时检测FPSA、TPSA及测其FPSA/TPSA比值,可以用于鉴别前列腺癌和良性前列腺增生: n TPSA在4.2-20ng/ml范围时, n FPSA/TPSA>0.25则癌的可能性极小,FPSA/TPSA<0.19...

PSA是前列腺癌的最佳标志物,主要用于前列腺癌早期诊断分期、评估和监测病情变化及各种治疗措施的疗效和随访。前列腺癌手术后,PSA浓度可逐渐降至正常,若手术后其浓度不降或下降后再次升高,应考虑肿瘤转移或
Age and prostate volume also had a significant relation P=0.054 but there was only a very weak relationship between PSA level and Histological diagnosis, (Pearson's correlation r=0.1).Conclusion: Age and prostate volume significantly correlate with serum PSA, just as age and prostate volume also...
Prostate specific antigen (PSA) is a protein that is produced by the cells of the prostate gland and enters the bloodstream. PSA testing is used to identify the early stages of prostate cancer. It is currently one of the few widely used tests for pr
Prostate specific antigen (PSA) is a type of protein produced by cells in the prostate. The prostate is a small reproductive gland that helps make semen, the fluid that transports sperm from the testicles through the penis during ejaculation. Healthy prostates create low levels of PSA. An eleva...
