弥漫大B细胞淋巴瘤预后研究进展

Research progress in prognosis of diffuse large B-cell lymphoma

弥漫大B细胞淋巴瘤（DLBCL）是最常见的非霍奇金淋巴瘤,具有高度异质性,高危患者预后差.如何更好地对DLBCL患者进行危险分层并早期识别高危患者是第58届美国血液学会（ASH）年会的一大热点.国际预后指数（IPI）作为经典的预后评分系统,在利妥昔单抗时代,其地位不断受到挑战,有多种新的预后评分系统被提出.分子生物学标记、基因突变在DLBCL的发生、发展中起重要作用,其预后价值备受关注.一些特殊DLBCL,如原发乳腺DLBCL、血管内大B细胞淋巴瘤、滤泡转化DLBCL以及复发难治DLBCL的预后也在该届年会上受到关注.

Diffuse large B-cell lymphoma （DLBCL） is the most common type of non-Hodgkin lymphoma with highly heterogeneous both clinically and biologically. So the prediction for prognosis of DLBCL and identifying patients with high risk are coming into the focus of the 58th American Society of Hematology （ASH） Annual Meeting. International prognostic index （IPI） risk model is widely known as the powerful prognostic indicator for DLBCL but in rituximab-era is challenged by a variety of new prognosis systems. Biological markers and mutation and expression of genes play an important role in the pathogenesis and progression of lymphoma, and its prognostic value draw much more attention. The prognostic factors of DLBCL, specific types, such as primary breast DLBCL, intravascular large B-cell lymphoma, the presence of a DLBCL component in a follicular lymphoma and relapsed/refractory DLBCL have been paid more attention in this meeting.
