摘 要:目的 探讨血清总PSA(t-PSA)、血清游离PSA与总PSA比值(f/t)、前列腺体积(PV)及PSA密度(PSAD)与前列腺上皮内瘤(prostaticintraepithelialneoplasia,PIN)的相关性及临床意义。方法收集我院2004年1月至2009年12月PIN患者165例,其中低级别PIN(10wgradeprostaticintraepithelialneoplasia,LGPIN)31例,高级别PIN(highgradeprostaticintraepithelialneoplasia,HGPIN)134例;以病理确诊的BPH患者252例和前列腺癌(prostatecancer,PCa)患者49例为对照组。BPH、LGPIN、HGPIN、PCa组年龄分别为(70.13±0.43)、(70.97±1.28)、(70.74±0.64)、(70.37±1.40)岁,IPSS分别为20.20±0.88、14.71±3.42、20.19±1.24、19.27±2.73,PV分别为(58.07±3.58)、(56.01±7.52)、(60.74±4.81)、(47.564-6.54)ml。分析比较4组间PSA、f/t、PSAD等的相关性和差异。结果4组年龄、IPSS和PV比较差异均无统计学意义(P〉0.05)。BPH、LGPIN、HGPIN、PCa组PSA值分别为(5.65±0.38)、(5.86±0.81)、(8.91±0.71)、(13.80±1.83)μg/L,f/t平均值分别为0.26±0.01、0.24±0.02、0.22±0.01、0.17±0.01;PSAD值分别为(0.11±0.01)、(0.10±0.02)、(0.19±0.03)、(0.48±0.12)μg/(L·cm3)。PSA、f/t和PSAD在LGPIN和HGPIN组间差异无统计学意义(P〉0.05),在LGPIN和BPH组间差异无统计学意义(P〉0.05),在LGPIN和PCa组间差异有统计学意义(P〈0.05),在HGPIN和BPH组间差异有统计学意义(P〈0.05);PSA和PSAD在HGPIN与PCa组间差异有统计学意义(P〈0.05)。HGPIN的ROC曲线中,血清PSA和PSAD的曲线下面积分别为0.6281和0.5919,两者比较差异无统计学意义(P〉0.05)。结论血清PSA和PSAD在HGPIN的早期预测中有诊断价值;PSAD有利于在PSA和f/t正常时鉴别HGPIN与PCa;LGPIN的临床特点接近于BPH,HGPIN则倾向�Objective To investigate the serum prostate specific antigen (tPSA), ratio of serum free PSA to total PSA (f/t) , prostate volume (PV) and prostate specific antigen density (PSAD), their correlation with prostatic intraepithelial neoplasia (PIN) and their clinical diagnostic significance. Methods Retrospectively evaluate 165 cases of patients with PIN (including 31 cases of LGPIN, 134 cases of HGPIN) , which confirmed by pathology, and 252 cases of benign prostatic hyperplasia (BPH) , 49 patients with prostate cancer (PCa) , both diagnosed by pathology, as control. The average age of BPH, LGPIN, HGPIN, PCa groups were 70.13± 0.43, 70.97±1.28, 70.74 ±0.64, 70.37 ±1.40, the International Prostate Symptom Score (IPSS) were 20.20± 0.88, 14.71 ± 3.42, 20.19 ±1. 239, 19.27± 2.73, and the PV were 58.07 ±3.58, 56.01 ±7.52, 60.74 ± 4.81, 47.56 ± 6.54, respectively. The data of PSA, f/t, PV and PSAD were analyzed and compared within the four groups. Results Age, IPSS score and PV had no significant difference among the four groups (P 〉 0.05). The PSA level of BPH, LGPIN, HGPIN, PCa groups were 5.65±0.38, 5.86 ±0.81, 8.91±0.71, 13.80 ±1.83, the f/t ratio were 0.26 ±0.01, 0.24±0.02, 0.22 ±0.01, 0. 167 ±0.01, and the PSAD level were0. 11 ±0.01, 0. 10 ±0.02, 0.19±0. 03, 0.48 ±0.12, respectively. PSA, f/t and PSAD were not significantly different between HGPIN and LGPIN ( P 〉 0.05 ) , and likewise between LGPIN and BPH patients ( P 〉 0. 05 ). PSA, f/t and PSAD were significantly different between LGPIN and PCa patients (P 〈 0.05 ) , and likewise between HGPIN and BPH patients ( P 〈 0.05 ). PSA and PSAD were significantly different between HGPIN and PCa ( P 〈 0.05 ). The areas under the ROC curve of PSA and PSAD of HGPIN were 0. 6281 ( P 〈 0.01 ) and 0. 5919 ( P 〈 0.05 ). Conclusions PSA and PSAD are correlated with HGPIN and can predict the existence of HGPIN early; PSAD can identify HGPIN and PCa, when PSA and f/t are no
