Blood:局限性和晚期滤泡性淋巴瘤的基因表达差异!

2020-02-01 QQY MedSci原创

滤泡性淋巴瘤(FLs)诊断为临床晚期III/IV期,常以t(14;18)为特征,其遗传背景已被大量阐明。以临床发生风险模型m7FLIPI为例的分子特征是风险分层的重要工具。相比之下,关于局限性FL(临床I/II期)的资料较少;局限性FL约占新诊断FL的20%,且t(14;18)的检出率仅为50%。为探讨局限性FL的遗传背景,研究人员对德国低级别淋巴瘤研究组3期试验中一致治疗的晚期或局限性FL患者进

滤泡性淋巴瘤(FLs)诊断临床晚期III/IV期,常以t(14;18)为特征,其遗传背景已被大量阐明。以临床发生风险模型m7FLIPI为例的分子特征是风险分层的重要工具。相比之下,关于局限性FL(临床I/II期)的资料较少;局限性FL约占新诊断FL的20%,且t(14;18)的检出率仅为50%。为探讨局限性FL的遗传背景,研究人员对德国低级别淋巴瘤研究组3期试验中一致治疗的晚期或局限性FL患者进行对比分析。

利用nCounter技术对110例局限性和556例晚期FL患者的184个基因进行靶向基因表达(GE)分析。通过Cox回归分析,不能确定晚期FL患者的预后GE信号,该结果与整体试验和单变量回归分析的结果一致。

相比之下,可以通过Penalized逻辑回归分析来定义可区分局限性和晚期FL的稳定GE特征。值得注意的是,在局限性FL队列中,3%携带一个“晚期特征”的样本表现出较差的无衰竭存活期(HR 7.1)。与此类似,在晚期队列中,7%的样本携带“局限期特征”,无衰竭存活期或总体存活期均延长。

总而言之,本研究结果支持局限性FL和晚期FL的生物学差异这一概念,这可能有助于改善局限性FL的预后。
