Blood:TP53高表达,可用于预测MCL患者预后不良。

2017-12-03 MedSci MedSci原创

目前,预测套细胞淋巴瘤治疗失败和总体存活时间是基于临床因素,包含套细胞淋巴瘤国际预后指数(MIPI)和根据Ki67评估的增殖情况。然而,P53和SOX11的免疫组化也可提高风险分层。Sietse M.Aukema等人在目前最新发表的淋巴瘤样本(365例)中行免疫组化检测SOX11和P53。所有患者都接受了欧洲MCL网络的前瞻性试验。在包含了MIPI和Ki67的多变量分析中,SOX11表达与患者治疗

目前,预测套细胞淋巴瘤治疗失败和总体存活时间是基于临床因素,包含套细胞淋巴瘤国际预后指数(MIPI)和根据Ki67评估的增殖情况。

然而,P53和SOX11的免疫组化也可提高风险分层。Sietse M.Aukema等人在目前最新发表的淋巴瘤样本(365例)中行免疫组化检测SOX11和P53。所有患者都接受了欧洲MCL网络的前瞻性试验。

在包含了MIPI和Ki67的多变量分析中,SOX11表达与患者治疗失败的时间无关联,但SOX11低表达的患者,总体存活期更短。

与此相反,无论是单变量分析还是根据MIPI和Ki-67校正的多变量分析,P53高表达是治疗失败时间的一个强有力的预测指标,而且与P53低表达的患者相比,P53高表达(50%以上的淋巴瘤细胞阳性)的患者总体存活期更短(风险比2.0,p=0.0054[治疗失败时间];HR 2.1,p=0.068[总体存活期])。

特别是P53高表达的患者治疗失败时间更短,总体存活期短,且不依赖于MIPI和Ki-67.

因此,P53免疫组化可作为常规诊断方法,评估套细胞淋巴瘤的预后。
