We aimed to identify subsets of patients who benefit from emergency LA and to establish a therapeutic algorithm for AML patients with hyperleukocytosis.
In this single-center retrospective cohort study, a total of 20 consecutive patients underwent LA because of their clinical symptoms. Overall survival (OS) analysis was conducted using the Kaplan-Meier plot method. Univariate and multivariate analyses (using multiple logistic regression) were performed. At the time of diagnosis, all patients received a standard diagnostic workup for AML including FLT3-ITD mutational analysis.
FLT3-ITD mut AML patients receiving LA had a median OS of 437 days (range 5-2379 days) with a corresponding 14-day survival of 92.3%, while FLT3 wt AML patients displayed a significantly lower median OS of only 5 days (range 1-203 days) with a corresponding 14-day survival of 14.3% ( = 0.0001).
Among patients with clinical symptoms of leukostasis, the subset of FLT3-ITD mut AML patients showed a better outcome with lower early mortality after emergency LA. Based on these observations, we established a therapeutic algorithm for AML patients with hyperleukocytosis.
我们旨在识别从紧急白细胞去除术（LA）中获益的患者亚组，并为高白细胞血症的急性髓系白血病（AML）患者建立一种治疗算法。
在这项单中心回顾性队列研究中，共有20例连续患者因临床症状接受了LA。使用Kaplan-Meier曲线法进行总生存（OS）分析。进行了单因素和多因素分析（使用多元逻辑回归）。在诊断时，所有患者均接受了包括FLT3-ITD突变分析在内的AML标准诊断检查。
接受LA的FLT3-ITD突变AML患者的中位OS为437天（范围5-2379天），相应的14天生存率为92.3%，而FLT3野生型AML患者的中位OS显著更低，仅为5天（范围1-203天），相应的14天生存率为14.3%（P = 0.0001）。
在有白细胞淤滞临床症状的患者中，FLT3-ITD突变AML患者亚组在紧急LA后早期死亡率较低，预后较好。基于这些观察结果，我们为高白细胞血症的AML患者建立了一种治疗算法。
