The introduction of pediatric-inspired regimens in adult Philadelphia-negative acute lymphoblastic leukemia (Ph-ALL) has significantly improved patients' prognosis. Within the Campus ALL network we analyzed the outcome of adult Ph-ALL patients treated according to the GIMEMA LAL1913 protocol outside the clinical trial, to compare the real-life data with the study results. We included 421 consecutive patients, with a median age of 42 years. The complete remission (CR) rate after the first course of chemotherapy was 94% and a measurable residual disease (MRD) negativity after the third course was achieved in 72% of patients. The 3-year overall survival (OS) and disease-free survival (DFS) were 67% and 57%, respectively. In a multivariate analysis, MRD positivity negatively influenced DFS. In a time-dependent analysis including only very high risk (VHR) and MRD positive cases, transplanted (HSCT) patients had a significantly better DFS than non-HSCT ones (P=0.0017). During induction, grade ≥2 pegaspargase-related hepato-toxicity was observed in 25% of patients (vs 12% in the GIMEMA LAL1913 trial, P=0.0003). In this large real-life cohort of Ph-ALL, we confirmed the very high CR rate and a superimposable OS and DFS compared to the GIMEMA LAL1913 clinical trial: CR rate after C1 94% vs 85%, P=0.0004; 3-year OS 67% vs 67%, P=0.94; 3-year DFS 57% vs 63%, P=0.17. HSCT confirms its important role in VHR and MRD-positive patients. The rate of pegaspargase-related toxicity was significantly higher in the real-life setting, emphasizing the importance of dose adjustment in the presence of risk factors to avoid excessive toxicity.

在成人费城阴性急性淋巴细胞白血病(Ph-ALL)中引入儿科启发方案后,患者的预后得到了显著改善。在 Campus ALL 网络中,我们分析了在临床试验之外按照 GIMEMA LAL1913 方案治疗的成人 Ph-ALL 患者的预后,以比较真实数据和研究结果。我们连续纳入了421名患者,中位年龄为42岁。第一疗程化疗后的完全缓解(CR)率为94%,72%的患者在第三疗程化疗后达到可测量残留疾病(MRD)阴性。3年总生存率(OS)和无病生存率(DFS)分别为67%和57%。在多变量分析中,MRD 阳性对 DFS 有负面影响。在一项仅包括极高风险(VHR)和MRD阳性病例的时间依赖性分析中,移植(造血干细胞移植)患者的生存期明显优于非造血干细胞移植患者(P=0.0017)。在诱导期间,25%的患者出现了≥2级的培加肝素酶相关肝毒性(GIMEMA LAL1913试验中为12%,P=0.0003)。与 GIMEMA LAL1913 临床试验相比,我们在这一大型 Ph-ALL 现实队列中证实了极高的 CR 率以及可叠加的 OS 和 DFS:C1 后 CR 率 94% vs 85%,P=0.0004;3 年 OS 67% vs 67%,P=0.94;3 年 DFS 57% vs 63%,P=0.17。造血干细胞移植证实了其在 VHR 和 MRD 阳性患者中的重要作用。在现实生活中,与 pegaspargase 相关的毒性发生率明显更高,这强调了在存在风险因素的情况下调整剂量以避免过度毒性的重要性。

Hydroxyurea (HU) is frequently used in the early phase of chronic myeloid leukemia (CML) to achieve cytoreduction prior to tyrosine kinase inhibitor (TKI) therapy. However, its impact on CML stem and progenitor cells (SPC) remains largely unknown. This study utilized targeted proteo-transcriptomic expression data on 596 genes and 51 surface proteins in 60,000 CD14-CD34+ cells from chronic phase CML patients to determine effects of shortterm HU treatment (4-19 days) on CML SPC. Peripheral blood and bone marrow samples were obtained from 17 CML patients eligible for short-term HU treatment (three patients before and after HU; seven patients before HU; and seven patients after HU) and subjected to single-cell CITE-seq and/or flow cytometry analysis. The analysis revealed enhanced frequencies of hemoglobin-expressing (HBA1, HBA2, HBB) erythroid progenitor cells in blood and bone marrow following HU treatment. In addition, there was an accumulation of cell subsets with S/G2/M phase-related gene and protein expression, likely representing cells arrested in, or progressing slowly through, the cell cycle. The increased frequency of cells in S/G2/M phase after HU was observed already among the most immature leukemic stem cells (LSC), and patients with a high fraction of LSC in the S/G2/M phase showed poor responsiveness to TKI treatment. We conclude that short-term HU treatment entails differentiation of erythroid progenitor cells and alters the characteristics of LSC in CML. The results imply that studies of LSC and progenitor populations in CML should take effects of initial HU therapy into account.

羟基脲(HU)常用于慢性髓性白血病(CML)的早期阶段,以在酪氨酸激酶抑制剂(TKI)治疗前实现细胞减少。然而,它对CML干细胞和祖细胞(SPC)的影响在很大程度上仍然未知。本研究利用来自慢性期CML患者的60,000个CD14-CD34+细胞中596个基因和51个表面蛋白的靶向蛋白质转录组表达数据来确定短期HU治疗(4-19天)对CML SPC的影响。研究人员从 17 名符合短期 HU 治疗条件的 CML 患者(3 名患者在 HU 治疗前后;7 名患者在 HU 治疗前;7 名患者在 HU 治疗后)处获得了外周血和骨髓样本,并对其进行了单细胞 CITE-seq 和/或流式细胞术分析。分析结果显示,HU 治疗后,血液和骨髓中表达血红蛋白(HBA1、HBA2、HBB)的红细胞祖细胞频率增加。此外,S/G2/M 期相关基因和蛋白表达的细胞亚群也在积累,这些细胞亚群可能代表了在细胞周期中停滞或进展缓慢的细胞。HU治疗后,在最不成熟的白血病干细胞(LSC)中已观察到处于S/G2/M期的细胞频率增加,而处于S/G2/M期的LSC比例较高的患者对TKI治疗的反应性较差。我们的结论是,短期HU治疗会导致红系祖细胞分化,并改变CML中LSC的特征。这些结果表明,对 CML 中 LSC 和祖细胞群的研究应考虑到初始 HU 治疗的影响。
