Chimeric antigen receptor T-cell (CAR-T) therapy is standard-of-care in relapse/refractory aggressive B-cell non-Hodgkin lymphoma. There are limited data regarding the impact of pre-existing chronic kidney disease (CKD) and acute kidney injury (AKI) post CAR-T and we sought to evaluate these in our patients.
In this single center retrospective analysis CKD cohort was defined KDIGO staging with eGFR of <60 mL/min/1.73 m2 (Stage ...3) at the time of pre-CAR-T assessment. Remaining patients constituted the no CKD group. AKI was defined by CTCAEv.4 and data were abstracted through Day 100 post-CAR-T therapy. The primary outcome was impact of pre-existing CKD on progression-free survival (PFS), overall survival (OS) and adverse events. Additionally, we also analyzed the impact of AKI on PFS and OS.
Thirty-two patients were identified with 7 having pre-existing CKD. Among the patients with or without CKD, the median PFS was 8.8 and 2.9 months respectively (pvalue 0.78). The median OS was 10 and 7 months respectively (p-value 0.64). AKI developed in a total of 9 patients (29%) post CAR-T, including 7 patients without CKD at baseline. The median PFS was 3.6 and 2.8 months for patients not developing AKI and developing AKI (p-value 0.84). Median OS in similar order was 10 and 3.9 months respectively (p-value 0.2). On univariate analysis, creatinine at baseline (p-value 0.018) and ICANS grade 2+ (p-value 0.016) were associated with an increased risk of developing AKI.
CKD or AKI after CAR-T showed no impact on post procedure OS and PFS.
嵌合抗原受体 T 细胞（CAR-T）疗法是复发/难治性侵袭性 B 细胞非霍奇金淋巴瘤的标准治疗方法。关于 CAR-T 后预先存在的慢性肾脏病（CKD）和急性肾损伤（AKI）的影响的数据有限，我们试图在我们的患者中评估这些。
在这项单中心回顾性分析中，CKD 队列根据 KDIGO 分期定义，在 CAR-T 前评估时 eGFR<60mL/min/1.73m2（阶段...3）。其余患者构成无 CKD 组。AKI 由 CTCAEv.4 定义，并通过 CAR-T 治疗后第 100 天的数据进行分析。主要结局是预先存在的 CKD 对无进展生存期（PFS）、总生存期（OS）和不良事件的影响。此外，我们还分析了 AKI 对 PFS 和 OS 的影响。
确定了 32 名患者，其中 7 名患有预先存在的 CKD。在有或没有 CKD 的患者中，中位 PFS 分别为 8.8 和 2.9 个月（p 值为 0.78）。中位 OS 分别为 10 和 7 个月（p 值为 0.64）。CAR-T 后共发生 AKI 9 例（29%），其中基线时无 CKD 7 例。未发生 AKI 和发生 AKI 的患者的中位 PFS 分别为 3.6 和 2.8 个月（p 值为 0.84）。中位 OS 也相似，分别为 10 和 3.9 个月（p 值为 0.2）。单因素分析显示，基线时的肌酐（p 值为 0.018）和 ICANS 等级 2+（p 值为 0.016）与 AKI 发生风险增加相关。
CAR-T 后 CKD 或 AKI 对术后 OS 和 PFS 没有影响。
