TL;DR
This study shows that combining venetoclax with chemotherapy is effective and safe for treating newly diagnosed acute leukemia of ambiguous lineage.
Contribution
The study provides new evidence on the efficacy and safety of venetoclax-based combination therapy for ALAL patients.
Findings
All 13 patients achieved complete remission after induction therapy with venetoclax and chemotherapy.
The 12-month overall survival rate was 64.5%, and the 12-month disease-free survival rate was 67.1%.
Treatment-related adverse events were manageable, with no fatal bleeding or neurological side effects.
Abstract
探讨维奈克拉(VEN)联合多药化疗治疗初诊未明系列急性白血病(ALAL)患者的疗效及安全性。 回顾性分析2021年6月至2024年7月在江苏省人民医院住院治疗的13例初诊ALAL患者的临床资料,13例患者的初始诱导治疗方案均为以VEN为基础联合多药化疗,其中VAA+P(VEN+阿扎胞苷/地西他滨+阿柔比星+醋酸泼尼松)方案治疗8例,V+IA(VEN+伊达比星+阿糖胞苷)方案治疗5例,FLT3突变患者联合FLT3抑制剂,Ph+患者联合酪氨酸激酶抑制剂治疗。分析患者的总生存(OS)期、无病生存(DFS)期及不良反应。 根据WHO造血与淋巴组织肿瘤分类第五版关于ALAL的免疫表型定义,13例ALAL患者包括T/髓系混合表型急性白血病(MPAL)4例,B/髓系MPAL 7例,ALAL-非特指型2例。其中4例B/髓系MPAL患者Ph(+),属ALAL特定的基因异常组别。3例患者存在FLT3突变(FLT3-TKD突变1例,FLT3-ITD突变2例)。于巩固治疗前评估VEN联合用药方案的诱导治疗效果:13例患者均获完全缓解(CR)。在随后的巩固治疗过程中,1例患者放弃治疗失访,9例患者进行异基因造血干细胞移植(allo-HSCT),其中4例因移植后并发症死亡,5例无病生存。3例患者(年龄≥70岁)按原方案巩固治疗,其中2例无病生存,1例因白血病中枢神经系统浸润死亡。13例患者的中位OS期未达到,75%位OS期为12.0个月,12个月累积OS率为64.5%,所有患者的中位DFS期未达到,75%位DFS期为8.2个月,12个月累积DFS率为67.1%。VEN联合方案诱导治疗期间及治疗后所有患者均发生3级或4级血液学不良反应,包括中性粒细胞减少和血小板减少。所有患者经初始诱导治疗后造血功能恢复且无致死性大出血发生;无患者出现肿瘤溶解综合征及神经系统不良反应;同时无3级及以上脏器不良反应发生(患者治疗前基础病除外)。 VEN联合多药化疗治疗初诊ALAL的疗效值得肯定且治疗的相关不良反应可耐受。
