摘要 近年来,随着诊治水平的提高及癌症患者生存时间的延长,有关患多个原发恶性肿瘤(multiple primary malignant neoplasms,MPMNs)或继发第二肿瘤(secondary malignant neoplasm,SMN)的报道越来越多。嵌合抗原受体T细胞免疫疗法(chimeric antigen receptor T-cell immunotherapy,CAR-T)是近年来迅速发展的肿瘤细胞免疫治疗方法,其通过基因工程技术在体外改造T细胞,加入识别肿瘤的结合区,同时加入T细胞激活所需的信号区(CD28、CD137等),使T细胞以非主要组织相容性复合物(major histocompatibility complex,MHC)方式与相应的肿瘤结合识别后活化而发挥抗肿瘤效应。已有临床试验数据显示,经CD19 CAR-T治疗的复发/难治急性B淋巴细胞白血病(relapsed/refractory B cell acute lymphoblastic leukemia,R/R B-ALL)和复发/难治性B细胞非霍奇金淋巴瘤(relapsed/refractory B cell non-Hodgkin's lymphoma,R/R B-NHL)的完全缓解率分别为70%~90%[1,2]和40%~58%[3,4],但目前依然有不可忽视的问题存在。本文报道2例弥漫性大B细胞淋巴瘤(diffuse large B cell lymphoma,DLBCL)接受CAR-T治疗后继发SMN,并文献复习。
