前列腺特异性抗原是一种重量为34,000的大分子糖蛋白,存在于前列腺的内质网和前列腺上皮细胞及其分泌物中。而前列腺磷酸酶则仅存在于溶酶体中。作者肯定前列腺特异性抗原与酸性磷酸酶对诊断和随访前列腺癌病人的敏感性和特异性。研究组共130例男性,分成40岁以下对照组30例;40例因良性前列腺肥大已作前列腺切除术者;60例经组织学证实为前列腺癌者。对照组病人平均前列腺特异性抗原水平为2.18
Prostate-specific antigen is a macromolecular glycoprotein with a weight of 34,000 and is present in the endoplasmic reticulum and prostatic epithelial cells of the prostate and its secretions. Prostate phosphatases are only present in lysosomes. The authors confirm the sensitivity and specificity of prostate-specific antigen and acid phosphatase in the diagnosis and follow-up of prostate cancer patients. A total of 130 males in the study group were divided into 30 patients under the age of 40; 40 patients had benign prostatic hypertrophy who had undergone prostatectomy; 60 patients were confirmed by histology as prostate cancer. The average prostate-specific antigen level in the control group was 2.18
