1641-三级淋巴结构预测实体瘤免疫治疗疗效

from 聊聊Sci

这项研究探讨了成熟三级淋巴结构 (mTLS) 在接受免疫检查点抑制剂治疗的癌症患者中的预测价值。研究人员通过对多个独立队列的大规模分析发现,肿瘤组织中成熟三级淋巴结构的存在与更高的治疗缓解率、更长的无进展生存期以及总生存期密切相关。值得注意的是,这种预测作用独立于传统的 PD-L1 表达水平和 CD8+ T 细胞密度,且在多种实体瘤类型中均表现出一致性。这些发现表明,成熟三级淋巴结构的检测可以作为一种比现有指标更精准的生物标志物,帮助筛选最能从免疫疗法中获益的患者。该研究不仅深化了对肿瘤免疫微环境的理解,也为推动精准免疫治疗提供了坚实的实证支持。References:Vanhersecke L, Brunet M, Guégan J P, et al.
