前列腺特异抗原（ＰＳＡ）是检测前列腺癌的最具临床价值的瘤标，为增加前列腺癌诊断的特异性和敏感性，近年来发现ＰＳＡ与前列腺体积、年龄、游离ＰＳＡ有关，从而出现了以下四种参数：ＰＳＡ密度、ＰＳＡ速率、特定年龄范围及游离ＰＳＡ与总ＰＳＡ百分率；采用ＲＴ－ＰＣＲ方法测定血液中产生ＰＳＡ的癌细胞，对前列腺癌的分期、治疗选择及预后估价起重要作用。本文就以上内容进行了综述。
Prostate specific antigen (PSA) is the most clinically valuable tumor marker for detecting prostate cancer. In order to increase the specificity and sensitivity of prostate cancer diagnosis, PSA has been found to be associated with prostate volume, age and free PSA in recent years, resulting in the following four Species parameters: PSA density, PSA rate, specific age range, and percentage of free PSA to total PSA; RT-PCR assay of PSA-producing cells in the blood plays an important role in the staging, treatment options and prognosis of prostate cancer. This article reviewed the above.
