Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is a high-risk subtype of ALL. We retrospectively studied 70 cases with Ph-like ALL and here present the largest study of CAR-T cell treatment and haplo-HSCT for this leukemia. Median age was 26 years and median leukocyte count was 31.44 × 10/L. The proportion of patients receiving chemotherapy, KIs, CAR-T cells, and allo-HSCT was 19%, 30%, 46%, and 61%, respectively. The overall response rate was 62%, 73%, and 100% after one month of KI treatment combined with chemotherapy, CAR-T cell therapy, and allo-HSCT, respectively. Five-year DFS and OS were 35% and 51%, respectively. The five-year cumulative incidence of relapse and non-relapse mortality was 63% and 11%, respectively. Allo-HSCT was associated with a better DFS ( = 0.010) and OS ( = 0.000) by univariate analysis. In conclusion, allo-HSCT after KIs together with chemotherapy or CAR-T cell therapy is a safe and feasible treatment modality for Ph-like ALL.
费城染色体样急性淋巴细胞白血病（Ph样ALL）是ALL的一种高危亚型。我们回顾性研究了70例Ph样ALL患者，在此展示了针对该白血病的最大规模的CAR-T细胞治疗和单倍体造血干细胞移植（haplo-HSCT）研究。中位年龄为26岁，中位白细胞计数为31.44×10⁹/L。接受化疗、激酶抑制剂（KIs）、CAR-T细胞和异基因造血干细胞移植的患者比例分别为19%、30%、46%和61%。在KI治疗联合化疗、CAR-T细胞治疗和异基因造血干细胞移植后1个月，总体缓解率分别为62%、73%和100%。五年无病生存率（DFS）和总生存率（OS）分别为35%和51%。五年复发和非复发死亡率的累积发生率分别为63%和11%。单因素分析显示，异基因造血干细胞移植与更好的DFS（P = 0.010）和OS（P = 0.000）相关。总之，在KI联合化疗或CAR-T细胞治疗后进行异基因造血干细胞移植是治疗Ph样ALL的一种安全可行的治疗方式。
