Blood:auto-HCT相比CAR-T疗法更适合用作获得部分缓解的DLCLC患者的巩固治疗!

2021-10-01 Nebula MedSci原创

对于挽救治疗后获得部分缓解的DLBCL患者,与CAR-T治疗相比,auto-HCT治疗与较低的复发率和较高的OS相关

中心点| 经挽救治疗后获得部分缓解的DLBCL患者,采用auto-HCT或CAR-T进行巩固治疗的两年PFS分别是52% vs 42%,两年OS分别是69% vs 47%。

弥漫性大B细胞淋巴瘤(DLBCL)是一种可治愈的疾病,约60%的患者接受以蒽环霉素为基础的和包含利妥昔单抗疗法的初始治疗后不需要进一步治疗。但是,一线治疗未能治愈的患者的预后往往较差,复发或难治性DLBCL患者常需要接受挽救治疗。

目前,对于经挽救化疗后获得部分缓解(PR)的DLBCL患者,采用自体造血干细胞移植(auto-HCT)与嵌合抗原受体T细胞(CAR-T)疗法作为巩固治疗的相对疗效尚不明确。

利用国际血液和骨髓移植研究中心注册数据库,Mazyar等研究人员通过CT或PET扫描筛查了在PR期间接受auto-HCT(2013-2019年)或CAR-T+Axicabtagene Ciloleucel(2018-2019年)治疗的成年DLBCL患者,然后使用单变量和多变量回归模型比较了两个队列之间经相关基线和临床因素调整后的临床结果。

接受auto-HCT或CAR-T疗法的患者的预后

在单变量分析中,两队列间的2年无进展生存期(52% vs 42%;p=0.1)和100天非复发死亡率(4% vs 2%;p=0.3)无明显差异;但采用auto-HCT进行巩固治疗与两年较低的复发/进展率(40% vs 53%;p=0.05)和优异的总生存率(OS:69% vs 47%;p=0.004)相关。

在多变量回归分析中,接受auto-HCT或CAR-T疗法的患者的预后

在多变量回归分析中,auto-HCT治疗与显著降低的复发/进展率风险(HR=1.49;p=0.01)和优越的OS(HR=1.63;p=0.008)相关

总体上,对于挽救治疗后获得部分缓解的DLBCL患者,与CAR-T治疗相比,auto-HCT治疗与较低的复发率和较高的OS相关。这些数据支持auto-HCT作为符合移植条件的经挽救治疗后获得部分缓解的DLBCL患者的巩固疗法。
