Prostate:表观遗传风险评分提高了对前列腺癌的风险评估。

侵袭性前列腺癌(PCA)的早期检测对患者的治疗效果仍然是至关重要的。然而,现有的前列腺癌筛查因其较高的过度诊断和过度治疗率而存在争议。为了更好地兼顾双方,在诊断时开发出更有效地评估疾病严重程度的方法是十分必要的。

侵袭性前列腺癌(PCA)的早期检测对患者的治疗效果仍然是至关重要的。然而,现有的前列腺癌筛查因其较高的过度诊断和过度治疗率而存在争议。为了更好地兼顾双方,在诊断时开发出更有效地评估疾病严重程度的方法是十分必要的。

研究者在一项包含102位接受标准12点前列腺活检穿刺术患者的前瞻性队列研究中探索DNA甲基化和高级别前列腺癌之间的关系。

EpiScore(通过量化前列腺活检组织中GSTP1, RASSF1和 APC的DNA甲基化强度后得出的一种评价标准),作为一种补偿活检组织欠抽样和改善诊断时危险分层的方法。

研究者发现,在诊断时格里森评分GS≥7分的癌症患者的穿刺活检组织中,GSTP1、RASSF1和APC的DNA甲基化强度高于GS≤6分的癌症患者,EpiScore在高级别活检组织和高NCCN风险分级的患者中较高也确认了这一点(均有P<0.001)。

有趣的是:在GS≥7的确诊患者中,DNA甲基化水平在高级别活检组织点以及其他无癌症活检组织点或低级别活检组织点中均增加(P < 0.001)。

将EpiScore和传统临床风险因素联合纳入Logistic回归模型中,对高GS评分患者的预测的曲线下面积(AUC)可达到0.82 (95%置信区间: 0.73-0.91) 。其中EpiScore、直肠指诊和非典型病理表现是最重要的贡献因素。

在被诊断为前列腺癌的患者中,DNA甲基化分析可以通过前列腺活检组织的区域效应检测出欠抽样的高风险PCA。当结合EpiScore和其他的临床风险因素时,预测准确度增加。这些结果表明:episcore可以在诊断时帮助发现那些隐匿性较高的恶性癌症患者,从而高效地选择出那些需要主动监测的患者。
