研究概要

胚系 CD19 多态性可能对套细胞淋巴瘤中 brexu-cel CAR-T 细胞治疗后的未来风险分层具有意义,但需要在更大的多中心队列中验证。

研究思路结论见上方概要

Brexu-cel是一种已确立的靶向CD19的CAR-T 细胞疗法,用于治疗复发/难治性套细胞淋巴瘤,但临床结局存在异质性,且决定应答的胚系因素尚不明确。

我们通过在一个接受brexu-cel CAR-T 细胞治疗的复发/难治性套细胞淋巴瘤患者的回顾性单中心队列中分析基因型与结局的关联,研究了CD19单核苷酸多态性rs2904880对该CAR-T 细胞治疗后治疗结局的临床影响。

总生存期因CD19多态性而异,携带V174纯合基因型的患者相比L174V杂合子患者生存期改善。

Brexu-cel is an established CD19-directed CAR-T cell therapy for relapsed or refractory mantle cell lymphoma, but clinical outcomes are heterogeneous, and germline determinants of response are poorly defined.

We investigated the clinical impact of the CD19 single-nucleotide polymorphism rs2904880 on treatment outcome after brexu-cel CAR-T cell therapy by analyzing genotype-outcome associations in a retrospective single-center cohort of patients with relapsed or refractory mantle cell lymphoma treated with this CAR-T cell therapy.

Overall survival varied according to CD19 polymorphism, with improved survival of patients carrying the V174 homozygous genotype compared with L174V heterozygotes.

The germline CD19 polymorphism may have implications for future risk stratification after brexu-cel CAR-T cell therapy in mantle cell lymphoma, but requires validation in larger, multicenter cohorts.
