Abstract
Data on the efficacy of high-dose chemotherapy and autologous stem cell transplantation (ASCT) for classical Hodgkin lymphoma (cHL) patients who failed a PET-driven first-line therapy are limited.We retrospectively evaluated 220 adult cHL patients who underwent ASCT from 2009 to 2021 at 11 centers in Italy. Overall, 49.5% had refractory disease, 23.2% relapsed < 12 and 27.3% ≥12 months from the end of first-line chemotherapy. The 3-year progression-free survival (PFS) and overall survival (OS) were 73.8% and 89.4%. In univariable analysis for PFS events PET-2+ (HR 2.69, p = .001), anemia (HR 2.22, p = .019), refractory disease (HR 1.76, p = .045), less than CR before ASCT (HR 3.24, p < .001) and >2 lines of salvage therapy (HR 2.52; p = .004) were associated with a higher risk of failure after ASCT. In multivariable analysis, >2 lines of salvage therapy (HR 3.28, p = .004) and RT before ASCT (HR 3.00, p = 0.041) retained significance.ASCT is an effective salvage approach for cHL patients treated in the era of PET-adapted therapies.

Abstract
In the 2022 European LeukemiaNet classification, patients with nucleophosmin 1 (NPM1)-mutated acute myeloid leukemia (AML) were classified in the adverse-risk category in the presence of high-risk cytogenetics (CG). Nonetheless, the impact of various CG aberrations on posttransplant outcomes remains to be unraveled. This registry study analyzed adult patients with NPM1-mutated de novo AML who underwent their first allogeneic hematopoietic cell transplantation in the first complete remission from 2005 to 2021. A total of 3275 patients were identified, 2782 had normal karyotype, 493 had chromosomal aberrations including 160 with adverse-risk CG, 72 patients had complex karyotype (CK), and 66 monosomal karyotype (MK). Overall, 2377 (73%) patients had FLT3-ITD. On univariate analysis, only FLT3-ITD, minimal/measurable residual disease (MRD) positivity and CK, but not abnormal CG, affected posttransplant outcomes. On multivariable analysis, CK was associated with lower overall survival (OS) (hazard ratio [HR] 1.72, p = .009). In the subgroup of 493 patients with aberrant CG, the 2-year leukemia-free survival (LFS) and OS were around 61% and 68%, respectively. On multivariable analysis for this subgroup, CK and MRD positivity were associated with increased risk of relapse (HR 1.7, p = .025; and 1.99, p = .003 respectively) and worse LFS (HR 1.62, p = .018; and 1.64, p = .011 respectively) while FLT3-ITD, MK, or other CG abnormalities had no significant effect. Importantly, CK negatively affected OS (HR 1.91, p = .002). In the first complete remission transplant setting, CK was found as the only cytogenetic risk factor for worse outcomes in NPM1-mutated AML. Nevertheless, even for this subgroup, a significant proportion of patients can achieve long-term posttransplant survival.

Abstract
We investigated whether secondary versus de novo acute myeloid leukaemia (AML) would be associated with poor outcomes in adult acute AML patients in first complete remission (CR1) receiving unrelated cord blood transplantation (CBT). This is a retrospective study from the acute leukaemia working party of the European Society for Blood and Marrow Transplantation. Inclusion criteria included adult at first allogeneic haematopoietic cell transplantation between 2000 and 2021, unrelated single or double unit CBT, AML in CR1, no ex vivo T-cell depletion and no post-transplant cyclophosphamide. The primary end-point of the study was leukaemia-free survival (LFS). A total of 879 patients with de novo (n = 696) or secondary (n = 183) AML met the inclusion criteria. In multivariable analyses, sAML patients had non-significantly different LFS (HR = 0.98, p = 0.86), overall survival (HR = 1.07, p = 0.58), relapse incidence (HR = 0.74, p = 0.09) and non-relapse mortality (HR = 1.26, p = 0.13) than those with de novo AML. Our results demonstrate non-significantly different LFS following CBT in adult patients with secondary versus de novo AML.

Abstract
Pediatric-inspired chemotherapy is the standard of care for younger adults with Philadelphia-negative acute lymphoblastic leukemia/lymphoma (Ph- ALL/LL). The GIMEMA LAL1913 trial tested a modified regimen adding pegaspargase 2000 IU/m2 to courses 1, 2, 5 and 6 of an eight-block protocol for patients 18-65 years, with dose reductions in patients >55 years. Responders were risk-stratified to allogeneic hematopoietic stem cell transplantation (HCT) or maintenance according to clinical characteristics and minimal residual disease (MRD). Out of 203 study patients (median age 39.8 years, 68.5% B-lineage), 185 (91%) achieved a complete remission (CR). The 3-year overall survival (OS), event-free (EFS) and disease-free (DFS) survival rates were 66.7% (95% confidence intervals, 64.4-60.1%), 57.7% (51.0-65.3%) and 63.3% (56.3-71.1%), respectively, fulfilling the primary study endpoint of a 2-year DFS >55%. While by intention-to-treat DFS was 74% and 50% in the chemotherapy (n=94) and HCT (n=91) assigment cohorts, a time-dependent analysis proved the value of HCT in eligible patients (DFS HCT 70% vs. no HCT 26%, P<0.0001). In multivariate analysis, age and MRD (n=151) were independent prognostic factors associated with DFS rates of 86% (age less/equal to 40/MRD-negative, n=66), 65% (age >40/MRD-negative, n=48), 64% (age less/equal to 40/MRD-positive, n=17) and 25% (age >40/MRD-positive, n=20) (P<0.0001). Grade 2/greater pegaspargase toxicity was mainly observed at course 1 (41 episodes in 32 patients), contributing to induction death in 2 patients, but was rare and milder thereafter. This pegarspargase-containing risk-oriented program was feasible and improved outcome of Ph- ALL/LL patients up to 65 years in a multicenter national setting. ClinicalTrials.gov #NCT02067143.

Abstract
Different doses of treosulfan plus fludarabine have shown advantage over reduced intensity regimens. However, data comparing higher doses of treosulfan to myeloablative busulfan are limited. Thus, we compared outcomes between FT14 (fludarabine 150/160 mg/m(2) and treosulfan 42 g/m(2), or FT14) over FB4 (fludarabine 150/160 mg/m(2) and busulfan 12.8 mg/kg). We retrospectively studied patients from European Society for Blood and Marrow Transplantation registry: a) adults diagnosed with acute myeloid leukemia (AML), b) recipients of first allogeneic hematopoietic stem cell transplantation (HSCT) from unrelated or sibling donor (2010-2020), c) HSCT at first or second complete remission, d) conditioning with FT14 or FB4. FT14 recipients (n = 678) were older, with higher rates of secondary AML, unrelated donors, peripheral blood grafts, and adverse cytogenetics, but lower percentage of female donor to male recipient compared to FB4 (n = 2025). Analysis was stratified on age. In patients aged < 55 years, FT14 was associated with higher relapse incidence (RI) and lower Leukemia-Free Survival (LFS). In patients aged≥55 years, acute GVHD CI was higher in FB4, without significant differences in other outcomes. Although FT14 has been used for higher-risk HSCT patients, our large real-world multicenter study suggests that FB4 is associated with better outcomes compared to FT14 in younger patients.

Abstract
The outcome of refractory/relapsed (R/R) acute leukemias is still dismal and their treatment represents an unmet clinical need. However, allogeneic transplantation (allo-HSCT) remains the only potentially curative approach in this setting. A prospective study (GANDALF-01, NCT01814488; EUDRACT2012-004008-37) on transplantation with alternative donors had been run by GITMO using a homogeneous myeloablative conditioning regimen with busulfan, thiotepa and fludarabine while GVHD prophylaxis was stratified by donor type. The study enrolled 101 patients; 90 found an alternative donor and 87 ultimately underwent allo-HSCT. Two-year overall survival of the entire and of the transplant population (primary endpoint) were 19% and 22%, without significant differences according to disease, donor type and disease history (relapsed vs refractory patients). Two-year progression-free survival was 19% and 17% respectively. The cumulative incidences of relapse and non-relapse mortality were 49% and 33% at two years. Acute grade II-IV and chronic GVHD occurred in 23 and 10 patients. Dose intensification with a myeloablative two-alkylating regimen as sole strategy for transplanting R/R acute leukemia does seem neither to improve the outcome nor to control disease relapse. A pre-planned relapse prevention should be included in the transplant strategy in this patient population.

Abstract
Cyclophosphamide is frequently substituted with fludarabine (Flu) in conditioning regimens before allogeneic hematopoietic cell transplantation (allo-HCT). We aimed to compare retrospectively, total body irradiation (12 Gy) plus Flu (FluTBI12) versus busulfan (Bu) plus Flu (FB4) as a myeloablative conditioning before allo-HCT in patients with acute myeloid leukemia (AML). Out of 3203 patients who met the inclusion criteria, 109 patients treated with FluTBI12 and 213 treated with FB4 were included in a final matched-pair analysis. In both groups, median patient age was 41 years, first or second complete remission (CR1/CR2) proportion was 78%/22%, allo-HCT from an unrelated donor was performed in 78% of patients. The probabilities of leukemia-free survival and overall survival at 2 years in FluTBI12 and FB4 groups were 65% vs. 60% (p = 0.64) and 70% vs. 72% (p = 0.87), respectively. The cumulative incidence of relapse was 19% vs. 29% (p = 0.11), while non-relapse mortality was 16% vs. 11%, respectively (p = 0.13). There were no statistical differences in both acute and chronic graft-versus-host disease (GVHD) incidence. The probability of GVHD-free, relapse-free survival (GRFS) was 49% for both groups. FluTBI12 and FB4 are comparable myeloablative regimens before allo-HCT in AML patients transplanted in CR1 and CR2.

Abstract
BACKGROUND The Collaboration to Collect Autologous Transplant Outcomes in Lymphoma and Myeloma (CALM) study has provided an opportunity to evaluate the real-world outcomes of patients with myeloma. The aim of this study was to compare the outcome according to the different subtypes of myeloma using CALM data. PATIENTS This study compared overall survival (OS), progression-free survival (PFS), and complete remission (CR) and the impact of novel versus non-novel drug containing induction regimens prior to autologous hematopoietic cell transplantation (HCT) of 2802 patients with "usual" and "rare" myelomas. RESULTS Our data suggest that IgM and non-secretory myeloma have superior PFS and OS compared with IgD myeloma and outcomes comparable to those for usual myeloma. Patients who received novel agent induction had higher rates of CR prior to transplant. Non-novel induction regimens were associated with inferior PFS but no difference in OS. Although not the primary focus of this study, we show that poor mobilization status is associated with reduced PFS and OS, but these differences disappear in multivariate analysis suggesting that poor mobilization status is a surrogate for other indicators of poor prognosis. CONCLUSION We confirm that IgD myeloma is associated with the worst prognosis and inferior outcomes compared with the other isotypes.

Abstract
We analyzed newly diagnosed multiple myeloma patients with del(17p) and/or t(4;14) undergoing either upfront single autologous (auto), tandem autologous (auto-auto) or tandem autologous/reduced-intensity allogeneic (auto-allo) stem cell transplantation. 623 patients underwent either auto (n?=?446), auto-auto (n?=?105), or auto-allo (n?=?72) between 2000 and 2015. 46% of patients had t(4;14), 45% had del(17p) while 9% were reported having both abnormalities. Five-year overall survival (OS) was 51% (95% confidence interval [CI], 45-58%) for single auto, 60% (95% CI, 49-72%) for auto-auto, and 67% (95% CI, 53-80%) for auto-allo (p?=?0.187). Five-year progression-free survival (PFS) was 17% (95% CI, 12-22%), 33% (95% CI, 22-43%), and 34% (95% CI, 21-38%; p?=?0.048). Five-year relapse rate was 82, 63, and 56%, while non-relapse mortality was 1, 4, and 10%. In multivariable analysis, in t(4;14) with single auto as reference, auto-auto (hazard ratio [HR], 0.44; p?=?0.007) and auto-allo (HR, 0.45; p?=?0.018) were associated with better PFS. In terms of t(4;14) and OS, auto-auto appeared to improve outcome compared with single auto (HR, 0.49; p?=?0.096). In del(17p), outcome in PFS was similar between single auto and auto-auto, while auto-allo appeared to improve PFS (HR, 0.65; p?=?0.097). No significant difference in OS was identified between the groups in patients with del(17p).
