CD19 chimeric antigen receptor T-cell (CART) therapy has revolutionized the treatment of patients with relapsed/refractory hematologic malignancies, especially B-cell acute lymphoblastic leukemia. As CART immunotherapy expands from clinical trials to FDA-approved treatments, a consensus among oncologists and hematopoietic cell transplant (HCT) physicians is needed to identify which patients may benefit from consolidative HCT post-CART therapy. Here, we review CD19 CART therapy and the outcomes of published clinical trials, highlighting the use of post-CART HCT and the pattern of relapse after CD19 CART. At this time, the limited available long-term data from clinical trials precludes us from making definitive HCT recommendations. However, based on currently available data, we propose that consolidative HCT post-CART therapy be considered for all HCT-eligible patients and especially for pediatric patients with KMT2A-rearranged B-cell acute lymphoblastic leukemia.
CD19嵌合抗原受体T细胞(CART)疗法彻底改变了复发/难治性血液系统恶性肿瘤患者的治疗方式,尤其是B细胞急性淋巴细胞白血病。随着CART免疫疗法从临床试验扩展到美国食品药品监督管理局(FDA)批准的治疗方法,肿瘤学家和造血细胞移植(HCT)医生需要达成共识,以确定哪些患者可能从CART治疗后的巩固性HCT中获益。在此,我们回顾CD19 CART疗法和已发表临床试验的结果,强调CART治疗后HCT的应用以及CD19 CART治疗后的复发模式。目前,临床试验中有限的长期可用数据使我们无法做出明确的HCT推荐。然而,基于目前可用的数据,我们建议对于所有符合HCT条件的患者,尤其是患有KMT2A重排的B细胞急性淋巴细胞白血病的儿科患者,考虑在CART治疗后进行巩固性HCT。
