BACKGROUND
Blinatumomab early-line treatment in B-cell precursor acute lymphoblastic leukemia (B-ALL) might improve clinical outcomes.
METHODS
We conducted a retrospective real-world cohort analysis in 20 newly diagnosed B-ALL patients who received reduced-dose chemotherapy (idarubicin, vindesine, and dexamethasone) for 1-3 weeks, followed by blinatumomab for 1-4 weeks as an induction therapy.
RESULTS
At the end of the induction therapy, a complete remission rate of 100% was achieved; 17 (85%) patients were minimal residual disease (MRD) negative (<1 × 10 ). Adverse events (AEs) were reported in 12 (60%) patients-43.8% were grade 1-2 and 56.2% were grade 3-4. No incidence of neurotoxicity or grade ≥3 cytokine release syndrome was reported.
CONCLUSIONS
Blinatumomab demonstrated a significant improvement in clinical outcomes in patients with newly diagnosed B-ALL irrespective of their poor-risk factor status and the pretreatment blast burden.
背景
Blinatumomab 在 B 细胞前体急性淋巴细胞白血病 (B-ALL) 中的早期治疗可能改善临床结局。
方法
我们对 20 例新诊断的 B-ALL 患者进行了回顾性真实世界队列分析，这些患者接受了 1-3 周的低剂量化疗（伊达比星、长春碱和地塞米松），随后接受 Blinatumomab 治疗 1-4 周作为诱导治疗。
结果
在诱导治疗结束时，完全缓解率达到 100%；17 例（85%）患者微小残留病（MRD）阴性（<1×10 ）。12 例（60%）患者发生不良反应（AE）-43.8%为 1-2 级，56.2%为 3-4 级。未报告神经毒性或≥3 级细胞因子释放综合征的发生率。
结论
Blinatumomab 使新诊断的 B-ALL 患者的临床结局显著改善，无论其是否存在不良风险因素和预处理 blast 负担。
