测定血清中前列腺特异性抗原 (PSA)是目前公认的前列腺癌指标之一 ,随着检测技术的发展 ,单纯检测 PSA特异性不高。近年采用前列腺特异性相关指标 :游离 PSA(F- PSA)与总 PSA(T- PSA)的比值、前列腺特异性抗原密度(PSAD)、前列腺特异性抗原移行区密度 (PSAT)、前列腺特异性抗原速度 (PSA速度 )作为前列腺癌诊断监测指标 ,大大提高了前列腺癌的诊断率。 F/ T、PSAD、PSAT、PSA速度为前列腺癌早期发现、监测及预后提供重要帮助
Determination of serum prostate specific antigen (PSA) is currently recognized as one of the indicators of prostate cancer, with the development of detection technology, simple detection of PSA specificity is not high. In recent years, prostate-specific related indicators: the ratio of free PSA (F-PSA) to total PSA (PSA), prostate specific antigen density (PSAD), prostate specific antigen transitional zone density (PSAT), prostate specific antigen Speed (PSA speed) as a diagnostic indicator of prostate cancer, greatly improving the diagnostic rate of prostate cancer. F / T, PSAD, PSAT, PSA Rates Provide Important Help for Early Detection, Monitoring and Prognosis of Prostate Cancer
