Urol Oncol:精液AMACR蛋白可以作为检测前列腺癌的新方法

2018-11-01 AlexYang MedSci原创

α-甲基酰基A辅酶消旋酶(AMACR)在前列腺癌(CaP)中是一种优秀的免疫组化生物标记。由于前列腺与尿道存在联系,研究人员假设精液将会是用来检测CaP特异性生物标记的理想活检样本,比如AMACR。最近,有研究人员探索和检测了精液AMACR蛋白在患有和不患有CaP男性中的情况。研究包括了28名活检确定的CaP患者,并在根治性前列腺切除术前搜集了精液样本,同时包括了15个年龄相匹配的对照。研究发现,

α-甲基酰基A辅酶消旋酶(AMACR)在前列腺癌(CaP)中是一种优秀的免疫组化生物标记。由于前列腺与尿道存在联系,研究人员假设精液将会是用来检测CaP特异性生物标记的理想活检样本,比如AMACR。最近,有研究人员探索和检测了精液AMACR蛋白在患有和不患有CaP男性中的情况。

研究包括了28名活检确定的CaP患者,并在根治性前列腺切除术前搜集了精液样本,同时包括了15个年龄相匹配的对照。研究发现,在28名CaP患者的精液中,23名(82%)检测到了精液AMACR蛋白,而在24名具有明显肿瘤大小(>0.5 cc或者0.3 g)的患者中,23名(96%)检测到了精液AMACR蛋白。在5名没有检测到AMACR的患者中,4名患者具有小的肿瘤体积(<1%或者0.3 g)。精液AMACR蛋白同样在没有癌症参与者的对照中检测到,比例为7/15(47%)。研究人员利用76ng/ml作为一个截断值,28名患者中的20名(71%)以及24名具有明显肿瘤体积中的20名(83%)患者均在AMACR蛋白检测中显示阳性,而在15名年龄匹配的对照中只有5名(33%)为阳性,并且,AMACR水平随着时间降解。

最后,研究人员指出,他们的研究是首次阐释了AMACR蛋白可以在精液中检测到。在CaP患者中检测到更高人数比例的情况表明了精液AMACR蛋白也许可以作为前列腺癌非侵入性检测的有用工具。进一步的研究也是需要的。
