概括
这项案例研究突出了一个扩散性大B细胞淋巴瘤 (DLBCL) 患者在连续治疗后实现长期缓解,包括epcoritamab和全原性造血干细胞移植 (HSCT). 作为复发DLBCL的桥梁疗法,epcoritamab显示出有前途的承诺.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
背景情况:
- 扩散性大B细胞淋巴瘤 (DLBCL) 在初始治疗几年后可能复发.
- 救援化疗,带血移植 (UCBT) 和仿真抗原受体T (CAR T) 细胞疗法是复发DLBCL的确立治疗方式.
- 在多种疗法后,治疗耐药或复发性DLBCL仍然是一个临床挑战.
研究的目的:
- 在初始完全代谢反应 (CMR) 后16年报告DLBCL复发病例.
- 评估epcoritamab作为桥梁疗法的疗效和安全性,在重度预先治疗的DLBCL患者的全源造血干细胞移植 (HSCT) 之前.
- 评估在CAR T细胞治疗失败后第二次HSCT后的长期结果.
主要方法:
- 一个单一中心病例报告详细介绍了一名53岁的女性患者的治疗过程,该患者患有复发性DLBCL.
- 连续治疗包括救援化疗,UCBT,CAR T细胞疗法,epcoritamab和第二个无关异基外围血液HSCT.
- 通过完整的代谢反应 (CMR) 和对诸如细胞因子释放综合征和移植与宿主疾病 (GVHD) 等不良事件的评估来监测患者的反应.
主要成果:
- 患者在救援化疗和UCBT后实现了第二次CMR,随后在CAR T细胞治疗后实现了第三次缓解.
- 尽管CAR T后的第三次复发,epcoritamab治疗导致CMR没有严重的并发症.
- 在接受epcoritamab之后,该患者接受了第二次全基性HSCT,并且在移植后一年以上保持了CMR,没有严重的并发症.
结论:
- 埃普科里塔马布证明了作为DLBCL复发的桥梁治疗的有效性和安全性,即使是在UCBT和CAR T细胞治疗后.
- 以epcoritamab进行连续治疗,然后进行全源性HSCT,可能是实现重度预治疗DLBCL患者长期存活的可行策略.
- 这一案例表明,epcoritamab可以克服治疗耐药性,并促进成功的后续HSCT.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.

Tumor Immunotherapy
1.7K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
