Sci Rep:循环miR-141和miR-375与转移去势抵抗性前列腺癌的治疗结果相关

2020-01-23 AlexYang MedSci原创

转移去势抵抗性前列腺癌(mCPRC)与高的死亡率相关,而疾病活性的控制到目前为止仍旧是一个主要的临床挑战。小RNA(miRs)在前列腺癌的诊断和预后中的作用已经有广泛的研究。最近,有研究人员在mCRPC患者中调查了循环miRs与治疗结果的关系。研究人员调查了84名mCRPC患者血浆样本中5个miRs(miR-93-5p、- 125b1 -5p、-141-3p、-221-3p和miR-375-3p)

转移去势抵抗性前列腺癌(mCPRC)与高的死亡率相关,而疾病活性的控制到目前为止仍旧是一个主要的临床挑战。小RNA(miRs)在前列腺癌的诊断和预后中的作用已经有广泛的研究。

最近,有研究人员在mCRPC患者中调查了循环miRs与治疗结果的关系。研究人员调查了84名mCRPC患者血浆样本中5个miRs(miR-93-5p、- 125b1 -5p、-141-3p、-221-3p和miR-375-3p)的相对表达量;其中40名患者进行的是多烯紫杉醇治疗(DOC群体),44名患者进行的是阿比特龙治疗(ABI群体)。研究发现,4个miRs(miR-93-5p、-141-3p、-221-3p和miR-375-3p)在多烯紫杉醇治疗起始后的表达水平显著降低,而miR-141-3p和miR-375-3p在放射治疗时再次增加。在接受阿比特龙治疗的患者中,miR-221-3p的血浆水平在第一次治疗周期后显著减少。在ABI群体中,miR-141-3p和miR-375-3p的高基线水平与更短的总生存(OS)显著相关,而在DOC群体中,高水平的miR-141-3p和miR-375-3p也与更短的OS显著相关。

最后,研究人员指出,miR-141-3p和miR-375-3p的血浆水平可能能够预测多烯紫杉醇或者阿比特龙治疗mCRPC患者中进展的时间。这些发现的临床影响依赖于更大群体的进一步鉴定。
