Abstract
BACKGROUND Post-transplant cyclophosphamide (PTCy) has emerged as a promising approach for preventing graft-versus-host disease (GVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, there is a lack of studies examining the impact of this GVHD prophylaxis when different donor types are used in patients with Hodgkin lymphoma (HL). OBJECTIVE To compare the outcomes of patients with HL undergoing HSCT from both HLA-matched donors, which include matched sibling donors (MSD) and matched unrelated donors (MUD), and haploidentical donors, using PTCy as GVHD prophylaxis approach in all cohorts. STUDY DESIGN We retrospectively compared transplant outcomes of allo-HSCT from 166 HLA-matched donors (96 siblings and 70 unrelated) and 694 haploidentical donors using PTCy-based GVHD prophylaxis in patients with HL registered in the EBMT database from 2010 to 2020. RESULTS Haploidentical transplantation showed significantly lower platelet engraftment (86% vs 94%, p<0.001) and higher rates of grades II-IV acute GVHD (24% vs 34%, p=0.01) compared to HLA-matched transplantation. The 2-year cumulative incidence of non-relapse mortality (NRM) was significantly lower in the HLA-matched cohort compared to haploidentical cohort (10% vs 18%, p=0.02), resulting in a higher overall survival (OS) rate (82% vs 70%, p=0.002). There were no significant differences observed in terms of relapse, progression-free survival, or GVHD-free relapse-free survival between the groups. In multivariable analysis, haploidentical transplantation was associated with an increased risk of grades II-IV acute GVHD, NRM, and worse OS compared to HLA-matched transplantation. CONCLUSIONS Our findings suggest that, in the context of PTCy-based GVHD prophylaxis, transplantation from HLA-matched donors appears to be a more favorable option compared to haploidentical transplantation.

Abstract
Hodgkin lymphoma (HL) patients who relapse after autologous-stem-cell- transplantation (auto-SCT) have traditionally had a poor prognosis. We analyzed 1781 adult HL patients who relapsed between 2006 and 2017 after a first auto-SCT. The 4-year overall survival (OS) after relapse continuously increased from 32% for patients relapsing in 2006-2008, to 63% for patients relapsing in 2015-2017 (p = 0.001). The improvement over time was predominantly noted in patients who had an early relapse (within 12 months) after auto-SCT (p = 0.01). On multivariate analysis, patients who relapsed in more recent years and those with a longer interval from transplant to relapse had a better OS, whereas increasing age, poor performance status, bulky disease, extranodal disease and presence of B symptoms at relapse were associated with a worse OS. Brentuximab vedotin (BV), checkpoint inhibitors (CPI) and second transplant (SCT2; 86% allogeneic) were used in 233, 91 and 330 patients respectively. The 4-year OS from BV, CPI, and SCT2 use was 55%, 48% and 55% respectively. In conclusion, the outcome after post-transplant relapse has improved significantly in recent years, particularly in the case of early relapse. These large-scale real-world data can serve as benchmark for future studies in this setting.

Abstract
BACKGROUND AIMS Around 50 000 autologous stem cell transplantations are done each year worldwide using cryopreserved peripheral blood stem cells (PBSCs). Cryopreservation is time-consuming and expensive. Since 2007, several retrospective studies have shown that PBSCs can be stored at 4°C for 2-3 days, allowing autologous stem cell transplantation in patients with multiple myeloma receiving high-dose melphalan. Data with non-cryopreserved PBSCs in patients autografted for lymphoma following longer pre-conditioning regimens are limited. In addition, no controlled comparison has been able to detect unforeseen differences. METHODS The authors compared outcomes of 94 consecutive adult patients with lymphoma (66 with Hodgkin lymphoma) autografted in our department in Oran (Algeria) using PBSCs stored at 4°C, from 2009 to 2018, with patients receiving cryopreserved stem cells reported to the European Society for Blood and Marrow Transplantation registry. Patients autografted in Oran were matched with patients receiving cryopreserved PBSCs in the registry (four controls per patient in Oran). RESULTS Neutrophil engraftment was significantly faster with cryopreserved PBSCs (P = 0.003). By day 10, only 17% of patients receiving non-cryopreserved PBSCs engrafted versus 48% for cryopreserved PBSCs. Likewise, platelet recovery to 20 000/mm(3) was significantly faster in patients receiving cryopreserved PBSCs (P = 0.01). However, all patients in both groups had recovered by day 20. There were no significant differences in non-relapse mortality (9% versus 7%, P = 0.4), relapse incidence (22% versus 32%, P = 0.13), progression-free survival (70% versus 61%, P = 0.4) or overall survival (85% versus 75%, P = 0.3). CONCLUSIONS This analysis suggests that, in patients with lymphoma receiving pre-transplant regimens such as carmustine, etoposide, cytarabine and melphalan, PBSCs stored at 4°C for up to 6 days can be used safely in centers with no cryopreservation facility. However, the kinetics of hematopoietic recovery showed a significant, albeit small, delay in engraftment for both neutrophils and platelets, which favors the use of cryopreservation if available.

Abstract
Anti-PD-1 monoclonal antibodies yield high response rates in patients with relapsed/refractory classic Hodgkin lymphoma (cHL), but most patients will eventually progress. Allogeneic hematopoietic cell transplantation (alloHCT) after PD-1 blockade may be associated with increased toxicity, raising challenging questions about the role, timing, and optimal method of transplantation in this setting. To address these questions, we assembled a retrospective cohort of 209 cHL patients who underwent alloHCT after PD-1 blockade. With a median follow-up among survivors of 24 months, the 2-year cumulative incidences (CIs) of non-relapse mortality and relapse were 14 and 18%, respectively; the 2-year graft-versus-host disease (GVHD) and relapse-free survival (GRFS), progression-free survival (PFS), and overall survival were 47%, 69%, and 82%, respectively. The 180-day CI of grade 3-4 acute GVHD was 15%, while the 2-year CI of chronic GVHD was 34%. In multivariable analyses, a longer interval from PD-1 to alloHCT was associated with less frequent severe acute GVHD, while additional treatment between PD-1 and alloHCT was associated with a higher risk of relapse. Notably, post-transplant cyclophosphamide (PTCy)-based GVHD prophylaxis was associated with significant improvements in PFS and GRFS. While awaiting prospective clinical trials, PTCy-based GVHD prophylaxis may be considered the optimal transplantation strategy for this patient population.

Abstract
Autologous hematopoietic stem cell transplantation (ASCT) is curative for a proportion of patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL). However, there is a small group of patients with high-risk of relapse after ASCT that might benefit from other approaches. We conducted a retrospective analysis on 126 patients treated with tandem ASCT-reduced intensity conditioning (RIC)-allogeneic-SCT and reported to the EBMT registry to analyze the efficacy and safety of this approach. Patients were included if they had received an ASCT followed by a planned RIC-SCT in <6 months without relapse between the procedures. The median time between diagnosis and ASCT was 16 months (2-174). The median number of lines prior to ASCT was two (33% of the patients received >3 lines). Forty-one percent were transplanted with active disease. The median follow-up was 44 months (6-130). Three-year-progression-free survival (PFS), overall survival (OS), incidence of relapse (IR), and non-relapse mortality (NRM) after the tandem were 53% (45-64), 73% (65-81), 34% (24-42), and 13% (8-21), respectively. This is the largest series analyzing the efficacy and safety of a tandem approach in R/R HL. The low NRM and IR with promising PFS and OS suggest that this might be an effective procedure for a high-risk population.

Abstract
We report on 59 Hodgkin lymphoma patients undergoing haploidentical stem cell transplantation (SCT; haplo-SCT) with posttransplant cyclophosphamide (PTCy) as graft-versus-host disease (GVHD) prophylaxis, comparing outcomes based on pretransplant exposure to checkpoint inhibitors (CPIs). Considering pretransplant characteristics, the 2 cohorts (CPI = 29 patients vs no-CPI = 30 patients) were similar, except for the number of prior lines of therapy (6 vs 4; P < .001). With a median follow-up of 26 months (range, 7.5-55 months), by univariate analysis, the 100-day cumulative incidence of grade 2-4 acute GVHD was 41% in the CPI group vs 33% in the no-CPI group (P = .456), whereas the 1-year cumulative incidence of moderate to severe chronic GVHD was 7% vs 8%, respectively (P = .673). In the CPI cohort, the 2-year cumulative incidence of relapse appeared lower compared with the no-CPI cohort (0 vs 20%; P = .054). No differences were observed in terms of overall survival (OS), progression-free survival (PFS), and nonrelapse mortality (NRM) (at 2 years, 77% vs 71% [P = .599], 78% vs 53% [P = .066], and 15% vs 21% [P = .578], respectively). By multivariable analysis, CPI before SCT was an independent protective factor for PFS (hazard ratio [HR], 0.32; P = .037). Stable disease (SD)/progressive disease (PD) was an independent negative prognostic factor for both OS and PFS (HR, 14.3; P < .001 and HR, 14.1; P < .001, respectively) . In conclusion, CPI as a bridge to haplo-SCT seems to improve PFS, with no impact on toxicity profile.

Abstract
BACKGROUND Allogeneic stem cell transplantation from haploidentical donor using an unmanipulated graft and post-transplantation cyclophosphamide (PT-Cy) is growing. Haploidentical transplantation with PT-Cy showed a major activity in Hodgkin lymphoma (HL), reducing the relapse incidence. The most important predictive factor of survival and toxicity was disease status before transplantation, which was better in patients with well controlled disease. METHODS We included 198 HL in complete (CR) or partial remission (PR) before transplantation. Sixty-five patients were transplanted from haploidentical donor and 133 from a HLA identical donor (both sibling and unrelated donors). Survival analysis was defined according to the EBMT criteria. Survival curves were generated by using Kaplan-Meier method and differences between groups were compared by the log rank test or by the log rank test for trend when appropriated. RESULTS The PFS, OS, and RI were significantly better in patients in CR compared to PR (55% vs 29% p?=?0.001, 74% vs 55% p?=?0.03, 27% vs 55% p? 0.001, respectively). The 2-year PFS was significantly better for HAPLO than HLA-id (63% vs 37%, p?=?0.03), without difference in OS. The 1-year NRM was not different. The 2-year relapse incidence (RI) was lower in the HAPLO group (24% vs 44%, p?=?0.008). Patients in CR receiving haplo HSCT showed higher 2-year PFS and lower 2-year RI than those allografted with HLA-id donor (75% vs 47%, p? 0.001 and 11% vs 34%, p?0.001, respectively). In multivariate analysis, donor type and disease status before transplantation were independent predictors of PFS as well as they predict the risk of relapse. Disease status at transplantation and age were independently associated to OS. CONCLUSIONS Nonetheless this is a retrospective study, limiting the wide applicability of results, data from this analysis suggest that HLA mismatch can induce a strong graft versus lymphoma effect leading to an enhanced PFS.

Abstract
Haploidentical stem cell transplantation (Haplo-SCT) with post-transplant cyclophosphamide (PT-Cy) represents a potential curative strategy for patients with Hodgkin lymphoma (HL) when a matched related or unrelated donor is not available. The role of graft source, either bone marrow (BM) or peripheral blood stem cells (PBSC) in this setting was not fully elucidated. We performed a retrospective study on 91 patients with HL in order to compare the outcome after BM (n=53) or PBSC (n=38) transplant. Eighty-nine patients engrafted with no difference between BM and PBSC in terms of median time for neutrophil (20 vs 20 days, p=0.405) and platelet (26 vs 26.5 days, p=0.994) engraftment. With a median follow-up of 40.2 months, 100-days cumulative incidence of grade 2-4 acute graft-versus host disease (GVHD) and grade 3-4 acute GVHD was 24% and 4%, respectively. Graft source was not associated with a different risk of acute GVHD both by univariate and multivariate analysis. Consistently, 1-year cumulative incidence of chronic GVHD was 7% with no differences between the two graft types (p=0.761). Two-year overall survival (OS), progression-free survival (PFS), non-relapse mortality (NRM) and GVHD/relapse-free survival (GRFS) were 67%, 58%, 20% and 52%, respectively. By univariate analysis, pre-transplant disease status was the main variable affecting all outcomes. By multivariate analysis, PBSC resulted a protective factor both for OS (HR: 0.29, p=0.006), PFS (HR: 0.38, p=0.001) and GRFS (HR: 0.44, p=0.020). The other independent variables affecting the final outcome were pre-transplant disease status and hematopoietic cell transplant comorbidity index (HCT-CI). In conclusion, when planning a Haplo-SCT with PT-Cy for patients with poor risk HL, graft type is an important variable to take into account when selecting the best available donor.

Abstract
The question of the best donor type between haploidentical (HAPLO) and matched-related donors (MRD) for patients with advanced HL receiving an allogeneic hematopoietic cell transplantation (allo-HCT) is still debated. Given the lack of data comparing these two types of donor in the setting of non-myeloablative (NMA) or reduced-intensity (RIC) allo-HCT, we performed a multicentre retrospective study using graft-vs.-host disease-free relapse-free survival (GRFS) as our primary endpoint. We analysed the data of 151 consecutive HL patients who underwent NMA or RIC allo-HCT from a HAPLO (N = 61) or MRD (N = 90) between January 2011 and January 2016. GRFS was defined as the probability of being alive without evidence of relapse, grade 3-4 acute GVHD or chronic GVHD. In multivariable analysis, MRD donors were independently associated with lower GRFS compared to HAPLO donors (HR = 2.95, P < 0.001). Disease status at transplant other than CR was also associated with lower GRFS in multivariable analysis (HR = 1.74, P = 0.01). In addition, the administration of ATG was independently linked to higher GRFS (HR = 0.52, P = 0.009). In summary, we observed significantly higher GRFS in HL patients receiving an allo-HCT using the HAPLO PT-Cy platform compared to MRD.

Abstract
Allogeneic stem cell transplantation is an alternative for patients with relapsed or refractory Hodgkin lymphoma (HL) but only limited data on unrelated umbilical cord blood transplantation (UCBT) are available. We analyzed 131 adults with HL who underwent UCBT in EBMT centers from 2003 to 2015. Disease status at UCBT was complete remission (CR) in 59 (47%) and almost all patients had received a previous autologous stem cell transplantation. The 4-year PFS and OS were 26% (95% CI 19-34%) and 46% (95% CI 37-55%), respectively. Relapse incidence was 44% (95% CI 36-54%) and non-relapse mortality (NRM) was 31% (95% CI 23-40%) at 4 years. In multivariate analysis, refractory/relapsed disease status at UCBT was associated with increased relapse incidence (HR=3.14 [95% CI 1.41-7.00], p=0.005) and NRM (HR=3.61 [95% CI 1.58-8.27], p=0.002), lower PFS (HR=3.45 [95% CI 1.95-6.10], p<0.001) and OS (HR=3.10 [95% CI 1.60-5.99], p=0.001). Conditioning regimen with cyclophospamide+fludarabine+2Gy total body irradiation (Cy+Flu+2 GyTBI) was associated with decreased risk of NRM (HR=0.26 [95% CI 0.10-0.64], p=0.004). Moreover, Cy+Flu+2 GyTBI conditioning regimen was associated with a better OS (HR=0.25 [95% CI 0.12-0.50], p<0.001) and PFS (HR=0.51 [95% CI 0.27-0.96], p=0.04). UCBT is feasible in heavily pretreated patients with HL. The reduced intensity conditioning regimen with Cy+flu+2 GyTBI is associated with a better OS and NRM. However, outcomes are poor in patients not in CR at UCBT.
