Abstract
PURPOSE Allogeneic hematopoietic cell transplantation (allo-HCT) is recommended in first complete remission (CR1) in acute myeloid leukemia (AML) patients harboring FLT3 internal tandem duplication (FLT3-ITD). We assessed changes over time in transplant characteristics and outcomes in AML patients aged 60 years and younger with a FLT3 ITD. EXPERIMENTAL DESIGN We identified 1827 adult AML patients (median age 49 years, range 18-60) with FLT3 ITD and intermediate karyotype, allografted between 2012 and 2021 in CR1. RESULTS NPM1 was mutated in 72% of patients. We compared changes over time in 688 patients transplanted between 2012 and 2016, and 1139 patients transplanted between 2017 and 2021. For patients with wild-type NPM1, the 2-year leukemia free survival (LFS) and overall survival (OS) significantly improved over time from 54% to 64% (hazard ratio [HR] =0.67; p=0.011) and from 63% to 71% (HR=0.66; p=0.021), respectively. Allo-HCT in recent years significantly reduced the cumulative incidence of relapse (CIR). For patients with NPM1 mutation, no significant changes over time were noted. CONCLUSIONS In AML patients with FLT3 ITDand wild-type NPM1, we noticed a significant decrease over time in the CIR and improvement of LFS and OS, likely reflecting the efficacy of FLT-3 inhibitors, including when used as post-transplant maintenance, in this high-risk setting. On the contrary, no significant change over time was noticed in outcomes of patients harboring a FLT3 and NPM1 mutation.

Abstract
BACKGROUND In autologous stem cell transplant (ASCT)-eligible myeloma patients, prolonged induction does not necessarily improve the depth of response. METHOD We analysed 1,222 ASCT patients who were classified based on (1) the interval between induction and stem cell collection, (2) the type of induction regimen: BID (Bortezomib, IMiDs and Dexamethasone), Bortezomib-based, or CTD (Cyclophosphamide, Thalidomide and Dexamethasone), and (3) the time to best response (Early i.e. best response within 4 or 5 months, depending on the regimen vs Late; Good i.e. VGPR or better vs Poor) RESULTS The length of induction treatment required to achieve a Good response did not affect PFS (p=0.65) or OS (p=0.61) post-ASCT. The three types of regimen resulted in similar outcomes: median PFS 31, 27.7 and 30.8 months (p=0.31), and median OS 81.7, 92.7, and 77.4 months, respectively (p=0.83). On multivariate analysis, neither the type nor the duration of the induction regimen affected OS and PFS, except for Early Good Responders who had a better PFS compared to Early Poor Responders (HR = 1.21, p value = 0.02). However, achieving a Good response at induction was associated with a better response (= VGPR) post-transplant CONCLUSION The kinetics of response did not affect outcomes.

Abstract
FLT3-ITD and NPM1 mutation refine prognostic stratification in acute myeloid leukemia (AML) with intermediate-risk cytogenetics. However, data on their role in patients undergoing autologous stem cell transplantation (Auto-SCT) as post-remission therapy (PRT) are limited. We therefore sought to retrospectively evaluate the role of FLT3-ITD and NPM1 in a cohort of AML patients (n = 405) with intermediate-risk cytogenetics, autografted in first complete remission (CR1). Patients were transplanted between 2000 and 2014 and reported to the European Society for Blood and Marrow Transplantation (EBMT) registry. Leukemia-free survival (LFS) was the primary outcome. Median follow-up was 5.5 years. FLT3-ITD(neg)/NPM1(WT) was the leading molecular subtype (50%), followed by FLT3-ITD(neg)/NPM1(mut) (30%). In the univariate analysis, molecular subtype was associated with LFS, overall survival (OS), and relapse incidence (RI) (p < 0.001); 5-year LFS: FLT3-ITD(neg)/NPM1(mut) 62%, FLT3-ITD(pos)/NPM1(mut) 38%, FLT3-ITD(neg)/NPM1(WT) 32%, and FLT3-ITD(pos)/NPM1(WT) 21%. At 5 years, OS and RI in the FLT3-ITD(neg)/NPM1(mut) subtype were 74% and 35%, respectively. The corresponding OS and RI in other subtypes were below 48% and over 57%. In a Cox multivariable model, molecular subtype was the strongest predictor of LFS, OS, and relapse. In conclusion, AML patients with intermediate-risk cytogenetics and FLT3-ITD(neg)/NPM1(mut) experience favorable outcomes when autografted in CR1, suggesting that Auto-SCT is a valid PRT option.

Abstract
Although high-dose therapy and autologous stem cell transplantation combined with novel agents is still the hallmark of first-line treatment in newly diagnosed transplant-eligible multiple myeloma, the impact of tandem autologous or autologous/reduced-intensity allogeneic transplant for patients with extramedullary disease and high-risk cytogenetics is not defined yet. Here, we analyzed clinical and cytogenetic data from 488 adult myeloma patients with extramedullary disease undergoing single autologous (n=373), tandem autologous (n=84), or autologous-allogeneic transplantation (n=31) between 2003 and 2015. At least one high-risk abnormality was present in 41% (n=202), with del(17p) (40%) and t(4;14) (45%) being the most frequent. More than one high-risk abnormality was found in 54%. High-risk cytogenetics showed worse 4-year overall survival and progression-free survival of 54% and 29% vs. 78% and 49% for standard-risk (p<0.001, respectively). Co-segregation of high-risk abnormalities did not seem to affect outcome. Regarding transplant regimen, overall and progression-free survival were 70% and 43% for single autologous vs. 83% and 52% for tandem autologous and 88% and 58% for autologous-allogeneic (p=0.06 and p=0.30). In multivariate analysis, high-risk cytogenetics were associated with worse survival (HR, 2.00; p=0.003) while tandem autologous significantly improved outcome vs. single autologous transplant (hazard ratios, 0.46 and 0.64; p=0.02 and p=0.03). Autologous-allogeneic transplant did not significantly differ in outcome but appeared to improve survival while results were limited due to small population (hazard ratio, 0.31). In conclusion, high-risk cytogenetics is frequently observed in newly diagnosed myeloma with extramedullary disease and significantly worsens outcome after single autologous while tandem autologous transplant strategy may overcome onset poor prognosis.

Abstract
BACKGROUND Assessment of measurable residual disease (MRD) is rapidly transforming the therapeutic and prognostic landscape of a wide range of hematological malignancies. Its prognostic value in acute lymphoblastic leukemia (ALL) has been established and MRD measured at the end of induction is increasingly used to guide further therapy. Although MRD detectable immediately before allogeneic hematopoietic cell transplantation (HCT) is known to be associated with poor outcomes, it is unclear if or to what extent this differs with different types of conditioning. METHODS In this retrospective registry study, we explored whether measurable residual disease (MRD) before allogeneic hematopoietic cell transplantation (HCT) for acute lymphoblastic leukemia is associated with different outcomes in recipients of myeloablative total body irradiation (TBI)-based versus chemotherapy-based conditioning. We analyzed outcomes of 2780 patients (median age 38 years, range 18-72) who underwent first HCT in complete remission between 2000 and 2017 using sibling or unrelated donors. RESULTS In 1816 of patients, no disease was detectable, and in 964 patients, MRD was positive. Conditioning was TBI-based in 2122 (76%) transplants. In the whole cohort MRD positivity was a significant independent factor for lower overall survival (OS) and leukemia-free survival (LFS), and for higher relapse incidence (RI), with respective hazard ratios (HR, 95% confidence intervals) of 1.19 (1.02-1.39), 1.26 (1.1-1.44), and 1.51 (1.26-1.8). TBI was associated with a higher OS, LFS, and lower RI with HR of 0.75 (0.62-0.90), 0.70 (0.60-0.82), and 0.60 (0.49-0.74), respectively. No significant interaction was found between MRD status and conditioning. When investigating the impact of MRD separately in the TBI and chemotherapy-based conditioning cohorts by multivariate analysis, we found MRD positivity to be associated with lower OS and LFS and higher RI in the TBI group, and with higher RI in the chemotherapy group. TBI-based conditioning was associated with improved outcomes in both MRD-negative and MRD-positive patients. CONCLUSIONS In this large study, we confirmed that patients who are MRD-negative prior to HCT achieve superior outcomes. This is particularly apparent if TBI conditioning is used. All patients with ALL irrespective of MRD status benefit from TBI-based conditioning in the myeloablative setting.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative therapeutic option for malignant hematopoietic diseases. Cytokines including transforming growth factor beta1 (TGFbeta1) play a pivotal role in immune reconstruction, and the development of graft versus host disease (GvHD) or infections. The aim of this study was to investigate the role of TGFB1 gene -1347C>T variant in the outcome of HSCT in a cohort of 409 adult recipient-donor pairs. TGFB1 variant was analysed from genomic DNA with LightCycler hybridisation probe method. In case of myeloablative conditioning, donor TGFB1 genotype correlated with overall survival (60-month OS for CC: 62.1 +/- 4.8%; CT: 46.8 +/- 4.8%; TT: 35.6 +/- 9.3%; p = 0.032), which was independent of age, donor type and GvHD prophylaxis in multivariate analysis (HR:2.35, 95%CI:1.35-4.10, p = 0.003). The cumulative incidence of acute GvHD grade III-IV [CC:10%; CT:17%; TT:24%], and non-relapse mortality was higher in TT-carriers (24-month NRM: CC:24%; CT:26%; TT:46%, p = 0.035). We did not find any association between recipient TGFB1 -1347C>T polymorphism and HSCT outcome. Our results suggest that donor TGFB1 -1347C>T may exert an adverse influence on the outcome of myeloablative conditioning transplantation.

Abstract
It has been shown recently that donor and/or recipient cytomegalovirus (CMV) seropositivity is associated with a significant overall survival (OS) decline in acute leukemia patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). We now analyzed the prognostic impact of the donor/recipient CMV serostatus in 6968 patients with chronic hematological malignancies who underwent allo-HSCT. Donor and/or recipient CMV seropositivity was associated with a significantly reduced 2-year progression-free survival (PFS, 50% vs. 52%, p = 0.03) and OS (62% vs. 65%, p = 0.01). Multivariate Cox regression analyses showed an independent negative prognostic impact of donor and/or recipient CMV seropositivity on PFS (HR, 1.1; 95% CI, 1.0-1.2; p = 0.03), OS (HR, 1.1; 95% CI, 1.0-1.2; p = 0.003), and non-relapse mortality (HR, 1.2; 95% CI, 1.0-1.3; p = 0.02). OS decline was strongest for CMV-seropositive recipients with a CMV-seronegative donor (HR, 1.2; 95% CI, 1.1-1.3), followed by CMV-seropositive patients with a CMV-seropositive donor (HR, 1.1; 95% CI, 1.0-1.2). Conversely, OS did not differ significantly between CMV-seronegative recipients allografted from a CMV-seropositive donor (HR, 1.0; 95% CI, 0.9-1.2) and patients with donor/recipient CMV seronegativity (p = 0.001 for the four groups together). Non-relapse mortality was also significantly (p = 0.01) higher for CMV-seropositive patients with a CMV-seronegative graft (HR, 1.2; 95% CI, 1.1-1.4) than for CMV-seropositive patients with a CMV-seropositive graft (HR, 1.1; 95% CI, 0.9-1.2) or CMV-seronegative recipients with a CMV-seropositive graft (HR, 1.0; 95% CI, 0.8-1.2). Donor and/or recipient CMV seropositivity still results in an OS decline in patients with chronic hematological malignancies who have undergone allo-HSCT. However, this OS decline seems to be lower than that described for acute leukemia patients previously.

Abstract
The role of HLA system in allogeneic haematopoietic stem cell transplantation (allo-HSCT) outcome is unarguable. In this study we investigated association of HLA-A,-B and-DRB1 alleles with overall survival (OS) in 186 patients undergoing allo-HSCT for lymphoid malignancies. Analyses confirmed significantly better OS for HLA-DRB1*04 carriers compared with non-carriers (p=0.01). Survival benefit was confined to male patients (in multivariate analyses p=0.034, hazard ratio 0.35, 95% confidence interval 0.13-0.92), whereas in females no difference was noted (p=0.82). Furthermore, donor gender also affected outcome and transplantation from female HLA-DRB1*04 carrier donors resulted in superior survival compared with female non-carrier donors (p=0.01). Combined analyses including recipient/donor gender and HLA-DRB1*04 showed that survival of male patients varied significantly according to donor gender and HLA-DRB1*04 carriership (p=0.04) with best survival among HLA-DRB1*04 carriers transplanted from female donors. Of relevance to our results, HLA-DRB1*04 has been documented as risk allele group for lymphoid malignancies, and studies described a male-specific risk. We believe that our findings provide further supporting evidence for sex-specific alterations secondary to HLA-DRB1*04 or related genes. Further studies are warranted to evaluate whether in contrast to general favour of male donors HLA-DRB1*04 carrier patients with lymphoid malignancies could benefit from transplantation from female donors.
