CLIN CANCER RES:miR-31-3p表达可以预测西妥昔单抗疗效

2019-01-21 MedSci MedSci原创

MiR-31-3p表达已被证明与抗EGFR治疗反应有关。CLIN CANCER RES近期发表了一篇文章,研究该生物标志物在FIRE-3研究人群中的预测作用,包括预测接受抗EGFR和抗VEGF治疗的患者预后的能力。

MiR-31-3p表达已被证明与抗EGFR治疗反应有关。CLIN CANCER RES近期发表了一篇文章,研究该生物标志物在FIRE-3研究人群中的预测作用,包括预测接受抗EGFR和抗VEGF治疗的患者预后的能力。

作者分析了参加FIRE-3试验的340名患有RAS WT mCRC患者原发性肿瘤中MiR-31-3p表达情况。164名患者随机接受FOLFIRI联合西妥昔单抗(FOLFIRI + Cetux)治疗,176名患者接受FOLFIRI联合贝伐单抗(FOLFIRI + Beva)治疗。根据miR-31-3p表达水平将患者进行分组,分析不同亚组的治疗效果。使用Kaplan-Meier曲线和Cox回归模型分析总生存(OS)和无进展生存(PFS)情况。使用logistic回归模型分析研究者评估的客观反应(iOR),6周时的肿瘤缩小(ETS)情况和集中评估的客观反应(cOR)。研究结果表明,与贝伐单抗相比,miR-31-3p低表达的患者接受西妥昔单抗治疗有更良好的PFS,OS,iOR,ETS和cOR。高表达患者治疗组之间的结果无差异。MiR-31-3p表达水平可预测PFS,OS,iOR,ETS和cOR。

文章最后认为,MiR-31-3p表达水平可以预测西妥昔单抗治疗RAS WT mCRC 患者的疗效。
