JCLA:健康汉族男性tPSA、fPSA和% fPSA的年龄特异性参考区间如何?

2017-07-24 MedSci MedSci原创

前列腺癌(PC)是男性最常见的恶性肿瘤之一,近年来已成为发展最快的恶性肿瘤。前列腺特异抗原(PSA)被广泛用作肿瘤标志物用于筛查。之前已经开展了许多研究以确定总循环PSA(tPSA)的参考区间(RIs)。结果表明tPSA的RIs在不同的国家和种族中是不同的,即使是在同一种族也可能不同。而有关游离PSA(fPSA)和总PSA(fPSA)的自由比率的研究较少。在本研究中,研究人员旨在同时确定tPSA,

近日,国际杂志 《Journal of Clinical Laboratory Analysis》在线发表一项关于健康的汉族男性中,tPSAfPSA% fPSA的年龄特异性参考区间的研究。

前列腺癌(PC)是男性最常见的恶性肿瘤之一,近年来已成为发展最快的恶性肿瘤。前列腺特异抗原(PSA)被广泛用作肿瘤标志物用于筛查。之前已经开展了许多研究以确定总循环PSA(tPSA)的参考区间(RIs)。结果表明tPSARIs在不同的国家和种族中是不同的,即使是在同一种族也可能不同。而有关游离PSA(fPSA)和总PSA(fPSA)的自由比率的研究较少。在本研究中,研究人员旨在同时确定tPSAfPSA %fPSA 年龄特异性Ris

在本项研究中,总共纳入了182621岁到94岁的健康男性。采用非参数95百分位间隔来定义RIs。在不同年龄组的参考极限(21-50 51-60,61 - 70,71 - 80,和≥81)分别为2.07,3.59,4.93,6.83,7.73 ng / mL tPSA fPSA的为0.60,0.76,0.83,1.30,1.30 ng / mL fPSA21-50男性为≥0.16,超过50岁为≥0.13

研究表明,本研究为tPSAfPSA% fPSA建立了年龄特异性的RIs。新的RIs应该更适合于中国汉族男性。对于医生来说,做出精确的医疗决定和适当的医疗干预是非常有价值的。
