用测定血液酸性磷酸酶(简称酸磷)值诊断前列腺癌,已达四十年之久。然而,由于不能分离出这种酶的“前列腺部分”(酸磷也可由前列腺以外的其它组织产生),因而缺乏特异性,诊断中可出现约10%的假阳性率。目前,国外已提出两种相当特异而且敏感的试验,从而使前列腺癌的早期发现成为可能。(一)Rose等致力于确定前列腺酸磷抗原的特异性。 With the determination of blood acid phosphatase (referred to as acid phosphate) value of diagnosis of prostate cancer, has reached 40 years. However, since the “prostatic portion” of this enzyme can not be isolated (acid phosphates can also be produced from tissues other than the prostate), there is a lack of specificity and a false positive rate of about 10% can be diagnosed. So far, two very specific and sensitive tests have been proposed abroad, making it possible to detect early stage prostate cancer. (A) Rose and others are committed to determining the specificity of prostaglandin phosphoprotein.
