Acute myeloid leukemia (AML) with translocation t(8;16)(p11;p13) represents a rare entity that has been categorized as a disease-defining recurring cytogenetic abnormality with adverse risk in the 2022 European LeukemiaNet classification. This rating was mainly based on a retrospective analysis comprising patients from several large clinical trials, which, however, included only 21 patients treated with allogeneic stem cell transplantation (alloSCT). Therefore, the European Society for Blood and Marrow Transplantation performed a registry study on a larger cohort to evaluate the role of alloSCT in t(8;16) AML. Sixty transplant recipients with t(8;16) AML were identified. Two-year overall and leukemia-free survival (OS/LFS) was 43/39%. Patients transplanted in first complete remission (CR1, n = 44) achieved a 2-year OS/LFS of 48%/48%. Following alloSCT in CR1, the multivariable analysis identified a complex karyotype (CK) as a major risk factor for relapse (HR 4.17, p = .016), lower LFS (HR 3.38, p = .01), and lower OS (HR 3.08, p = .017). Two-year OS/LFS of patients with CK was 19%/19%, in contrast to 67%/67% in patients with t(8;16) outside a CK. Other factors for inferior outcomes were older age and secondary AML. In summary, alloSCT could mitigate the adverse risk of patients with t(8;16) AML not harboring a CK, particularly when performed in CR1.
急性髓性白血病(AML)t(8;16)(p11;p13)易位是一种罕见的疾病,在2022年欧洲白血病网络(European LeukemiaNet)的分类中被归类为具有不良风险的疾病定义复发性细胞遗传学异常。这一分类主要基于对几项大型临床试验患者的回顾性分析,但其中仅包括21名接受异基因干细胞移植(alloSCT)治疗的患者。因此,欧洲血液与骨髓移植学会(European Society for Blood and Marrow Transplantation)对更大规模的人群进行了登记研究,以评估异体干细胞移植在t(8;16)急性髓细胞性白血病中的作用。这项研究确定了 60 例 t(8;16) AML 移植受者。两年总生存率和无白血病生存率(OS/LFS)分别为43%和39%。首次完全缓解(CR1,n = 44)的移植患者的两年OS/LFS为48%/48%。CR1患者接受异体移植后,多变量分析发现复杂核型(CK)是导致复发(HR 4.17,p = .016)、较低LFS(HR 3.38,p = .01)和较低OS(HR 3.08,p = .017)的主要风险因素。CK患者的两年OS/LFS分别为19%/19%,而CK以外的t(8;16)患者的两年OS/LFS分别为67%/67%。导致不良预后的其他因素包括年龄偏大和继发性急性髓细胞性白血病。总之,allSCT可以减轻t(8;16)急性髓细胞性白血病患者不携带CK的不利风险,尤其是在CR1期进行allSCT时。

According to current recommendations, older AML patients in first complete remission (CR) after induction chemotherapy should receive consolidation with intermediate-dose cytarabine (IDAC). However, no study has demonstrated the superiority of IDAC over other regimen. In this retrospective study, we compared the efficacy of mini-consolidations (idarubicin 8 mg/m2 day 1, cytarabine 50 mg/m2/12 h, day 1-5) and IDAC. Inclusion criteria were newly diagnosed AML, age > 60 years, first CR after induction and at least 1 cycle of consolidation. Of the 796 included patients, 322 patients received mini-consolidations and 474 patients received IDAC. Mini-consolidation patients were older, and more often, they had de novo AML and unfavorable risk. The rate of allogeneic transplantation was higher in the IDAC group. The median number of cycles was higher in the mini-consolidation group (4 vs. 2; p < .0001). Median relapse-free survival was 18 months with mini-consolidations and 12 months with IDAC (p = .0064). In multivariate analysis, the risk of relapse or death was significantly higher in the IDAC group (p = .004). Median OS was 36 versus 31 months with mini-consolidations or IDAC, respectively (p = .46). In multivariate analysis, the consolidation regimen had no significant influence on OS (p = .43). In older AML patients, post-remission therapy with mini-consolidations represents an alternative to IDAC.
根据目前的建议,诱导化疗后首次完全缓解(CR)的老年急性髓细胞白血病患者应接受中剂量阿糖胞苷(IDAC)巩固治疗。然而,还没有研究证明IDAC优于其他方案。在这项回顾性研究中,我们比较了迷你巩固疗法(伊达比星 8 毫克/平方米,第 1 天;阿糖胞苷 50 毫克/平方米/12 小时,第 1-5 天)和 IDAC 的疗效。纳入标准为新诊断的急性髓细胞性白血病,年龄大于 60 岁,诱导后首次 CR,至少巩固治疗一个周期。在纳入的796名患者中,322名患者接受了迷你巩固治疗,474名患者接受了IDAC治疗。接受迷你巩固治疗的患者年龄较大,且多为新发急性髓细胞性白血病患者,风险较低。IDAC组的异基因移植率更高。迷你合并组的周期中位数更高(4 vs. 2; p

Despite the introduction of JAK inhibitors, allogeneic hematopoietic cell transplant remains the only potentially curative treatment for patients with myelofibrosis but has considerable treatment-related complications. Whether the incorporation of JAK inhibition into the transplant algorithm leads to improved outcomes is still unclear. Here, we analyzed different transplant platforms in myelofibrosis patients undergoing a first transplant, comparing immune profiles and outcomes of (1) 33 patients continuing JAK inhibition at start of conditioning until stable engraftment (PERI-group), (2) 38 patients receiving JAK inhibition prior to transplant until start of conditioning (PRE-group), and (3) 38 patients that had never received JAK inhibition (NON-group). Patients in the PERI-group showed significantly higher early B-cell recovery as well as significantly increased late recovery of gamma-delta T cells and NK cells. We observed excellent neutrophil and platelet engraftment (100% for both) in the PERI-group and no hematotoxic effects or increased rates of infections following peri-transplant JAK inhibition. Cumulative incidence of acute graft-versus-host disease (GvHD) grade II-IV at day 100 after transplant was 15% in the PERI-group versus 29% in the PRE-group versus 34% in the NON-group. Cumulative incidence of relapse at 1 year after transplant was 9% in the PERI-group compared with 16% in the PRE-group and 18% in the NON-group. In conclusion, peri-transplant JAK inhibition was feasible with promising engraftment and acute GvHD rates, though deserves further investigation.
尽管引入了JAK抑制剂,异基因造血细胞移植仍是骨髓纤维化患者唯一可能治愈的治疗方法,但治疗相关并发症也相当多。将JAK抑制剂纳入移植算法是否会改善治疗效果,目前仍不清楚。在此,我们对首次接受移植的骨髓纤维化患者的不同移植平台进行了分析,比较了(1)33 例患者在调理开始时继续使用 JAK 抑制剂直至稳定移植(PERI 组);(2)38 例患者在移植前接受 JAK 抑制剂直至调理开始(PRE 组);(3)38 例患者从未使用过 JAK 抑制剂(NON 组)的免疫概况和预后。PERI 组患者的早期 B 细胞恢复能力明显提高,后期γ-δ T 细胞和 NK 细胞恢复能力也明显提高。我们观察到,PERI 组患者的中性粒细胞和血小板移植效果极佳(均为 100%),而且在移植前抑制 JAK 后没有出现血液毒性反应或感染率升高。移植后第 100 天,急性移植物抗宿主病(GvHD)II-IV 级的累积发生率在 PERI 组为 15%,在 PRE 组为 29%,在 NON 组为 34%。移植后 1 年,PERI 组的累积复发率为 9%,而 PRE 组为 16%,NON 组为 18%。总之,移植前抑制 JAK 是可行的,其移植率和急性 GvHD 发生率都很乐观,但仍值得进一步研究。

High‐grade B‐cell lymphoma not otherwise specified (HGBCL, NOS) has overlapping morphological and genetic features with diffuse large B‐cell lymphoma (DLBCL) and Burkitt lymphoma (BL), leading to uncertainty in its diagnosis and clinical management. Using functional genomic approaches, we previously characterized HGBCL and NOS, that demonstrate gene expression profiling (GEP), and genetic signatures similar to BL. Herein, we characterize distinct HGBCL, NOS, cohort (n = 55) in adults (n = 45) and in children (n = 10), and compared the GEP, genomic DNA copy number (CN), and mutational spectrum with de novo DLBCL (n = 85) and BL (n = 52). This subgroup, representing ~60% of HGBCL, NOS, lack gene‐expression signature of BL and double hit/dark zone lymphoma, but express DLBCL like signatures and are characterized by either GCB‐ or ABC‐like mRNA signatures and exhibit higher genomic complexity, similar to de novo DLBCL, and show alteration in genes regulating B‐cell activation (CD79B, MYD88, PRDM1, TBLIXR1, CARD11), epigenome (KMT2D, TET2) and cell cycle transition (TP53, ASPM). However, recurrent mutations in genes often mutated in BL (DDX3X, GNA13, CCND3), but rare in DLBCL, are also present in HGBCL‐NOS, highlighting genetic heterogeneity. Consistent with mutation spectrum, frequent genomic CN alterations in genes regulating B‐cell activation (del‐PRDM1, gain‐BCL6, ‐REL, ‐STAT3) and cell cycle regulators (del‐TP53, del‐CDKN2A, del‐RB1, gain‐CCND3) were observed. Pediatric cases showed GCB‐DLBCL‐like mRNA signatures, but also featured hallmark mutations of pediatric BL. Frequent oncogenic PIM1 mutations were present in adult HGBCL, NOS. In vitro analyses with pharmacologic or genetic inhibition of PIM1 expression triggered B‐cell activation and NF‐κB‐induced apoptosis, suggesting that PIM1 is a rational therapeutic target.

Relapse is the major cause of treatment failure in Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study aimed to evaluate the effect of a prophylactic tyrosine kinase inhibitor (TKI) strategy on relapse in this population. Patients were assigned to prophylactic or control groups based on measurable residual disease (MRD) pre-transplantation. The primary endpoint was the cumulative incidence of relapse. A total of 110 patients with Ph+ ALL undergoing allo-HSCT were enrolled in this prospective study. Thirty-eight patients with positive MRD pre-transplantation were included in the prophylactic group, and 72 with negative MRD pre-transplantation were included in the control group. The 4-year cumulative incidence of relapse was 25.3% (95% CI: 12.1%–41.0%) and 20.3% (11.6%–30.7%; HR = 1.272, 95% CI: 0.551–2.940, p = .549), and non-relapse mortality was 10.5% (3.3%–22.7%) and 9.7% (4.2%–17.9%; HR = 1.094, 95% CI: 0.320–3.738, p = .928) in the prophylactic and control groups. The 4-year overall survival was 71.8% (53.2%–84.1%) and 84.1% (72.9%–90.9%; HR = 1.746, 95% CI: 0.741–4.112, p = .196), and leukemia-free survival was 64.1% (45.8%–77.7%) and 70.0% (57.6%–79.4%; HR = 1.212, 95% CI: 0.607–2.421, p = .585) in the prophylactic and control groups. Our results suggest that prophylactic TKI post-HSCT in patients with positive MRD pre-transplantation can produce outcomes comparable to negative MRD pre-transplantation without TKI post-HSCT.

The impact of measurable residual disease (MRD) in relapse/refractory multiple myeloma (RRMM) patients treated with T-cell redirecting immunotherapy is uncertain. We analyzed MRD dynamics using next-generation flow in 201 patients treated in clinical trials with chimeric antigen receptor (CAR) T cells and T-cell engagers (TCE). Achieving MRD negativity at 10−6 was associated with 89% reduction in the risk of progression and/or death. Survival outcomes were improved in patients with sustained versus transient MRD negativity and were dismal in those who remained MRD positive. The intent-to-treat MRD negative rates were higher in patients treated with CAR T cells versus TCE. However, among patients achieving MRD negativity, there were no differences in survival outcomes when stratified according to treatment with CAR T cells versus TCE. In multivariate analysis including the number of prior lines of treatment, International Staging System, cytogenetic risk, extramedullary disease and type of T-cell redirecting immunotherapy, only the complete remission (CR) and MRD statuses showed independent prognostic value for progression-free and overall survival. In conclusion, our study shows that deep and sustained MRD negative CR is the most relevant prognostic factor and should be considered as the treatment endpoint in RRMM patients treated with CAR T cells and TCE.
在接受T细胞重定向免疫疗法治疗的复发/难治性多发性骨髓瘤(RRMM)患者中,可测量残留疾病(MRD)的影响尚不确定。我们利用新一代流式细胞术分析了在嵌合抗原受体(CAR)T细胞和T细胞吞噬体(TCE)临床试验中接受治疗的201名患者的MRD动态。MRD阴性率达到10-6与病情进展和/或死亡风险降低89%相关。MRD持续阴性与短暂阴性相比,患者的生存状况有所改善,而MRD持续阳性的患者生存状况则不容乐观。接受 CAR T 细胞治疗的患者的意向治疗 MRD 阴性率高于接受 TCE 治疗的患者。然而,在获得 MRD 阴性的患者中,根据 CAR T 细胞治疗与 TCE 治疗进行分层后,生存结果并无差异。在包括既往治疗次数、国际分期系统、细胞遗传学风险、髓外疾病和T细胞重定向免疫疗法类型在内的多变量分析中,只有完全缓解(CR)和MRD状态对无进展生存期和总生存期具有独立的预后价值。总之,我们的研究表明,深度和持续的MRD阴性CR是最相关的预后因素,应被视为接受CAR T细胞和TCE治疗的RRMM患者的治疗终点。
