Clin Cancer Res: 醋酸阿比特龙治疗的前列腺癌患者中游离DNA修饰动态研究

2018-04-11 AlexYang MedSci原创

对醋酸阿比特龙(AA)的原发性抗性能够在20%-40%的患者中发生,醋酸阿比特龙是治疗转移性去势难治性前列腺癌的关键的治疗药物。最近,有研究人员鉴定了能够对AA治疗响应进行预测的生物标记和阐释了治疗抗性相关的机制。研究人员对来自33名AA治疗患者的108份血浆样本进行了游离循环DNA(cfDNA)修饰情况分析。研究发现,在AA敏感和AA抗性患者相比中,有30个胞嘧啶表现出了显著的修饰差异(FDR

研究人员对来自33名AA治疗患者的108份血浆样本进行了游离循环DNA(cfDNA)修饰情况分析。研究发现,在AA敏感和AA抗性患者相比中,有30个胞嘧啶表现出了显著的修饰差异(FDR q<0.05),其中的21个胞嘧啶修饰在治疗之前就已经存在差异化修饰。另外,AA敏感患者而不是AA抗性患者,在开始AA治疗后不久就丢失了cfDNA修饰的个体差异,但是这样的变化在治疗后期重新恢复到了起始水平。

最后,研究人员指出,他们的研究对AA治疗响应的预测提供了一系列的潜在生物标记,强调了使用胞嘧啶修饰变异作为生物标记的诊断价值,同时也为AA敏感患者前列腺癌复发的机制提供了一些新的见解。
