中心点:

研究人员推断出一种7基因印迹,可鉴别对硼替佐米或以来那度胺为基础的疗法更敏感的骨髓瘤患者。

根据印迹治疗的效果不次于采用硼替佐米、来那度胺和地塞米松联合治疗。

摘要:

改善多发性骨髓瘤患者的预后不仅要开发新的疗法,更要更好的应用现有的治疗措施。Michael A. Chapman等人采用II期PADIMAC(以硼替佐米、阿霉素和地塞米松[PAD]联合治疗未进行过治疗的多发性骨髓瘤患者:延期ASCT患者的微小残留病灶[MRD]的影响)研究招募的新确诊的患者的样本,进行RNA测序(RNA-Seq)。

研究人员利用合成退火和大边界最近邻算法,开发了一种7基因印迹来预测治疗预后,并在采用以硼替佐米和来那度胺为基础的疗法治疗的独立队列中验证该印迹。

该印迹可区分哪些患者对哪种疗法的反应性更好。在CoMMpass(将多发性骨髓瘤临床预后与个人遗传图评估联系起来)数据集中,与传统治疗的患者相比,根据印迹正确治疗的患者的无进展存活期和总体存活期均更长(中位值:20.1个月 vs 未达到,危险比 0.40,95% CI 0.23-0.72,p=0.0012;30.7个月 vs 未达到,危险比 0.41,95% CI 0.21-0.80,p=0.0049)。

总而言之,上述根据印迹正确治疗的患者的预后并不次于采用硼替佐米、来那度胺和地塞米松联合(美国的标准疗法)治疗的患者。该印迹仅包含7个基因,便于应用于临床,有助于指导更多的靶向药物应用于骨髓瘤。
