Prostate Cancer P D:前列腺癌分子变异和相关MRI特性分析

2017-08-10 AlexYang MedSci原创

多参数的核磁共振成像(mpMRI)在前列腺癌(PCa)中的使用频率正在增加。最近的研究鉴定了不同的PCa分子亚类,且具有复发性基因组变异特征。然而,在前列腺癌中的分子变异与mpMRI相关的特性仍旧是未知的。基于该背景,最近,有研究人员调查了前列腺癌中复发性分子变异与mpMRI特性的相关关系。研究中,研究恩怨62个大于0.5厘米的前列腺癌瘤进行了手术前的mpMRI,并对囊肿进行了ERG重排、PTEN

多参数的核磁共振成像(mpMRI)在前列腺癌(PCa)中的使用频率正在增加。最近的研究鉴定了不同的PCa分子亚类,且具有复发性基因组变异特征。然而,在前列腺癌中的分子变异与mpMRI相关的特性仍旧是未知的。基于该背景,最近,有研究人员调查了前列腺癌中复发性分子变异与mpMRI特性的相关关系。

研究中,研究恩怨62个大于0.5厘米的前列腺癌瘤进行了手术前的mpMRI,并对囊肿进行了ERG重排、PTEN缺失、SPINK1超表达、SPOP突变和CHD1缺失评估。每一个前列腺癌病灶都与相关的mpMRI位置进行匹配,并根据PI-RADSv2模块,通过单观测器进行病变部位评分。

研究发现,在62个囊肿中,22个(35.5%)表现为ETG阳性,6(9.7%)个表现为SPINK1超表达,6个(9.7%)表现为SPOP突变,4个(6.5%)表现为CHD1缺失,1个(1.6%)表现为PTEN缺失。并且所有具有CHD1缺失的囊肿在mpMRI中不是可视化的,但是所有具有SPINK1超表达的囊肿在mpMRI中是可视化的,尽管相关性并不显著(P=0.06)。另外,分子变异与PI-RADS得分严重度没有显著的相关性(P>0.05)。

最后,研究人员表示,该调查是首次阐释分子变异与前列腺癌囊肿mpMRI特性相关性的文章。该研究也可以为未来的研究作为假设发展,从而严格地评估特异的PCa分子亚类与成像特性的关系,从而进一步扩展MRI在前列腺癌鉴定中的作用。
