摘要
本文对8例非转移性前列腺癌和20例前列腺增生的前列腺特异性抗原密度(PSAD)进行研究显示,两者平均值分别为0.734和0.085(P<0.001)。7例PSAD>0.2者均为前列腺癌;其中3例PSA<10ng/ml,1例<2.8ng/ml。而15例PSAD<0.1者无1例前列腺癌;其中7例PSA>2.8ng/ml。表明PSA轻中度增高或正常时,PSAD不失为一项前列腺癌早期筛选诊断的有效指标。
Prostate specific antigen density(PSAD) was studied in 8 cases of non- metastatic prostate cancer and 20 cases of BPH. The mean PSAD values for prostate cancer and BPH were 0. 734 and 0. 085 respectively (P<0. 001). All of 7 patients with PSAD greater than 0. 2 had prostate cancer in which 3 had a PSA less than 10ng/ml and 1 below 2. 8ng/ ml. In contrast, none of 15 patients with PSAD less than 0. 1 had prostate cancer. Furthermore, 7 out of 15 BPH patients were found to have a PSA greater than 2. 8ng/ml. These results showed that PSAD might be an effective indicator in screening of early prostate cancer when the serum PSA is moderately elevated or normal.
