对14例血清前列腺特异性抗原(PSA)值>10ng/ml的良性前列腺增生症(BPH)患者(BPH组)及12例前列腺癌(PC)患者(PC组)进行了术前PSA及前列腺特异性抗原密度(DPSA)测定。结果BPH织PSA值为29.61±15.89ng/ml,DPSA值为0.60±0.36;PC组PSA值为85.89±53.76ng/ml,DPSA值为1.93±1.31,两组间PSA及DPSA。均有统计学差异(P<0.002)。认为当血清PSA力10ng/ml时.PSA几乎不能区分BPH和PC,而DPSA以0.7为标准值时,其诊断价值则明显优于PSA。同时分析厂造成BPH者PSA值>10ng/ml的可能原因。
Preoperative PSA and prostate specificities were performed in 14 patients with benign prostatic hyperplasia (BPH) and 12 patients with prostate cancer (PC) with serum prostate specific antigen (PSA)> 10 ng / ml Sex antigen density (DPSA) assay. Results The PSA value of BPH was 29.61 ± 15.89ng / ml, the DPSA value was 0.60 ± 0.36; the PSA value of PC group was 85.89 ± 53.76ng / ml, the DPSA value was 1.93 ± 1.31 , PSA and DPSA between the two groups. There was statistical difference (P <0.002). When serum PSA power 10ng / ml. PSA is almost indistinguishable from BPH and PC, whereas DPSA has a significantly better diagnostic value than PSA at 0.7. At the same time, the possible causes of PSA> 10ng / ml in BPH patients were analyzed.
