Serum prostatic specific antigen (PSA) and prostatic acid phosphatase (PAP) were evaluated with double monoclonal radioimmunoassays. In 250 patients with prostatic cancer the normal limits were as follows: PSA 0.1-2.7 ng/ml, and PAP 1.09 +/- 0.45 ng/ml (mean +/- SD). In 91 untreated patients with non-metastatic tumours, 42.8% had PSA greater than 10 ng/ml and 18.6% had PAP greater than 2 ng/ml. In 60 untreated patients with metastatic disease PSA was greater than 10 ng/ml in 91.7%; PAP was greater than 2 ng/ml in 65%. In prolonged remission PSA was generally less than 5 ng/ml and PAP less than 2 ng/ml. Longitudinal studies of 2-4 years showed the independence of these markers and a higher correlation of changes in the PSA level and clinical status than given by parallel PAP measurements. In non-metastatic disease, PSA greater than 10 ng/ml at presentation, with or without a coincidentally raised PAP, carried an increased risk of progression within 2 years.
采用双单克隆放射免疫分析法对血清前列腺特异性抗原(PSA)和前列腺酸性磷酸酶(PAP)进行评估。在250例前列腺癌患者中,正常范围如下:PSA为0.1 - 2.7 ng/ml,PAP为1.09±0.45 ng/ml(均值±标准差)。在91例未经治疗的非转移性肿瘤患者中,42.8%的患者PSA大于10 ng/ml,18.6%的患者PAP大于2 ng/ml。在60例未经治疗的转移性疾病患者中,91.7%的患者PSA大于10 ng/ml;65%的患者PAP大于2 ng/ml。在长期缓解期,PSA一般小于5 ng/ml,PAP小于2 ng/ml。2至4年的纵向研究表明,这些标志物相互独立,与并行的PAP测量相比,PSA水平变化与临床状态的相关性更高。在非转移性疾病中,初诊时PSA大于10 ng/ml,无论PAP是否同时升高,2年内进展风险均增加。
