| 摘 要： | 目的:比较TuM2-PK，tPSA，fPSA/tPSA和PSAD在PSA灰区对前列腺癌的诊断价值。方法:选取tPSA在4～10 ng/mL的前列腺癌（PCa）、良性前列腺癌增生（BPH）及前列腺炎老年患者共252例，测其血中TuM2-PK，tPSA和fPSA，计算fPSA/tPSA比值；经直肠B超测前列腺体积，计算tPSA与前列腺体积之比，得到PSAD。用SPSS19.0分析TuM2-PK，tPSA，fPSA/tPSA和PSAD在PSA灰区对PCa的诊断价值。结果:PCa组的TuM2-PK，fPSA/tPSA和PSAD较比前列腺炎老年组及BPH组均有显著变化(P<0.05)；3组间的tPSA没有显著差异(P>0.05)。TuM2-PK AUC(0.948)>PSAD AUC(0.801)> fPSA/tPSA AUC (0.610)> tPSA AUC (0.499)。当TuM2-PK，tPSA，fPSA/tPSA和PSAD最佳临界值分别取24.30 U/mL、6.60 ng/mL、0.16和0.15 ng/mL/cm3时，诊断PCa的敏感性和特异性分别为88.9%和92.1%，72.2%和44.9%，80.5%和60.2%，83.3%和71.8%。结论:在PSA灰区，TuM2-PK、fPSA/tPSA、PSAD均能提高PCa诊断的敏感性和特异性，且TuM2-PK比fPSA/tPSA和PSAD对于PCa的诊断具有更高的准确性。

| Abstract: | Objective: To explore diagnostic significance of TuM2-PK, tPSA, fPSA/tPSA and PSAD for prostate cancer in PSA gray area. Methods: Two hundred and fifty-two cases with prostatic cancer (PCa), benign prostatic hyperplasia (BPH) and prostatitis whose tPSA levels were between 4 ng/mL and 10 ng/mL were chosen. Plasmatic TuM2-PK and serum fPSA, tPSA were examined. Prostate volume was determined by transrectal ultrasound. PSAD and fPSA/tPSA were calculated. The diagnostic significance of TuM2-PK, tPSA, fPSA/tPSA and PSAD for PCa in PSA gray area were analyzed using SPSS19.0. Results: Compared with BPH group and elderly prostatitis group, TuM2-PK, fPSA/tPSA and PSAD in PCa group were significantly changed (P<0.05); There was no significant difference in tPSA among the three groups. The AUC of these indexes in descending order was TuM2-PK, PSAD, fPSA/tPSA, and tPSA． While the cutoffs of TuM2-PK, tPSA, fPSA/tPSA and PSAD were 24.30 U/mL, 6.60 ng/mL, 0.16 and 0.15 ng/mL/cm3, the sensitivity and specificity of diagnosed PCa were 88.9% and 92.1%，72.2% and 44.9%，80.5% and 60.2%，83.3% and 71.8%, respectively. Conclusion: TuM2-PK, fPSA/tPSA and PSAD can increase sensitivity and specificity inthediagnosis of PCa in PSA gray area. And compared with fPSA/tPSA and PSAD, TuM2-PK is more accurate in diagnosing PCa.? |
