对于在接受新型免疫治疗药物后达到疾病缓解的患者,Allo-SCT 巩固治疗是一种安全且可治愈的选择,对于 CAR-T 细胞治疗后复发的患者而言,这可能是一种理想的挽救策略。
双特异性 T 细胞衔接抗体、免疫检查点抑制剂及抗体药物偶联物等新型免疫治疗药物,常用于嵌合抗原受体(CAR)T 细胞疗法后复发的非霍奇金淋巴瘤患者挽救治疗。然而,这些药物对异基因干细胞移植(Allo-SCT)结局的潜在长期影响尚不清楚。
我们回顾性分析了 CAR-T 细胞疗法时代之前,接受免疫治疗后进行 Allo-SCT 的 27 例复发/难治性非霍奇金淋巴瘤患者结局,并与 28 例接受常规治疗后进行 Allo-SCT 的历史队列进行比较。
两组在移植物抗宿主病/复发无生存期(4 年,59% 对 46%)、总生存期(4 年,77% 对 44%)、非复发死亡率(4 年,19% 对 22%)以及急性(6 个月,15% 对 21%)和慢性(4 年,18% 对 24%)移植物抗宿主病方面结局相近。值得注意的是,免疫治疗后复发的累积发生率较低(4 年,4% 对 14%),但差异未达到统计学显著性。两组巨细胞病毒和真菌感染的累积发生率无差异。
对新型免疫治疗药物治疗后达到疾病缓解的患者,以 Allo-SCT 巩固治疗是一种安全且可能治愈的选择;对于 CAR-T 治疗后复发的患者,这可能是值得考虑的挽救策略。
We retrospectively analyzed the outcomes of 27 relapsed/refractory non-Hodgkin lymphoma patients receiving Allo-SCT after immunotherapy in the pre-CAR T-cell therapy era and compared them with a historical cohort of 28 subjects undergoing Allo-SCT after conventional therapy.
The two cohorts had similar outcomes in terms of graft-versus-host disease/relapse-free survival (4 years, 59% versus 46%), overall survival (4 years, 77% versus 44%), non-relapse mortality (4 years, 19% versus 22%) and acute (6 months, 15% versus 21%) and chronic (4 years, 18% versus 24%) graft-versus-host disease. Of note, the cumulative incidence of relapse was lower after immunotherapy (4 years, 4% versus 14%), although significance was not reached. The cumulative incidence of cytomegalovirus and fungal infection did not differ among the two cohorts.
Consolidation with Allo-SCT is a safe and curative option for patients achieving disease response after new immunotherapy drugs that could represent a desirable salvage strategy for patients relapsing after CAR T-cell therapy.
