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
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
Effective salvage options inducing high complete metabolic response (CMR) rates without significant toxicity are needed for Hodgkin lymphoma (HL) patients failing induction treatment and who are candidate to autologous stem cell transplantation (ASCT). Brentuximab vedotin (BV) and bendamustine are active monotherapies in the relapsed/refractory setting and their combination (the BBV regimen) possibly enhances their activity. This single-arm multicenter phase 2 study investigated the efficacy and safety of BBV as first salvage therapy in 40 patients with relapsed/refractory HL. Thirty-eight patients were evaluable for efficacy: 30 (78.9%) had a CMR and 2 (5.3%) a partial response, leading to an overall response rate (ORR) of 84.2%. The ORR in the primary refractory subset was 75.0%, among relapsed patients it was 94.4%. Thirty-five patients could mobilize peripheral blood stem cells and 33 underwent ASCT. At a median follow-up of 23 months, the estimated 3-year overall survival and progression-free survival are 88.1% and 67.3%. During therapy, only 3 grade IV cases of neutropenia occurred and resolved within a week. No grade 4 extrahematologic toxicities were reported; skin reactions were however rather frequent (65%). These results suggest that the BBV regimen exhibits promising efficacy and a manageable toxicity in a challenging subpopulation of HL patients.

Abstract
This monocentric retrospective study included 70 consecutive relapsed/refractory Hodgkin lymphoma (RR-HL) patients receiving reduced-intensity allogeneic stem cell transplantation (alloSCT). We evaluated overall and progression-free survival (OS, PFS), graft-versus host disease/relapse-free survival (GFRS), and chronic GVHD-free OS (cGVHD-free OS) defined as OS without moderate-to-severe cGVHD. Patients had a median age of 33 years (range, 18-60 years), 23% had refractory disease (SD/PD). Donors were HLA identical (39%), unrelated (30%), or haploidentical (31%). Median follow-up was 6.2 years. Five-year OS was 59% and PFS was 49%. NRM was 16% at 1 year. 44% of patients had cGVHD, and 14% moderate-to-severe cGVHD at last follow-up. GFRS and cGVHD-free OS were 26 and 48% at 5 years. In multivariate analysis, resistant disease at alloSCT impacted survival and GFRS. In conclusion, disease response before alloSCT impacts survival and GFRS. GVHD outcomes may help comparing the long-term effects of the new salvage treatments that bridge patients to alloSCT.

Abstract
BACKGROUND The treatment of patients with Hodgkin lymphoma (HL) who develop disease progression after undergoing allogeneic stem cell transplantation (allo-SCT) remains challenging. METHODS The authors assessed outcomes in 184 adult patients with HL who developed disease recurrence or progression after a matched related or unrelated allo-SCT at European Society for Blood and Marrow Transplantation-participating centers between 2010 and 2014. RESULTS Eighty patients who received brentuximab vedotin (BV) salvage therapy were compared with 104 patients who did not. Patients in the BV group were younger (median age of 30 years vs 34 years) and were more likely to receive pretransplant BV (65% vs 46%) or posttransplant donor lymphocyte infusion (66% vs 33%). The 2 groups otherwise were comparable. Patients in the BV group received a median of 6 doses of posttransplant BV, resulting in a complete remission rate of 29%, a partial response rate of 45%, and a stable disease rate of 26%. Response to BV after allo-SCT did not appear to be affected by receipt of pretransplant BV. Despite a longer median follow-up for surviving patients in the BV group (33 months vs 23 months; P<.001), approximately 34% of the original BV cohort were alive and in CR at the time of last follow-up versus 18% in the group that did not receive BV (P=.003). The use of BV before donor lymphocyte infusion was found to be associated with the highest probability of being alive and in CR (40%) at the time of last follow-up. Salvage BV appeared to have no effect on chronic graft-versus-host disease or 1-year overall survival from the time of disease recurrence after allo-SCT (76% vs 67%). CONCLUSIONS BV is a safe and effective salvage therapy for patients with HL who develop disease recurrence or progression after undergoing allo-SCT, even after prior exposure to BV.

Abstract
Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate. Preliminary data suggest that BV might improve outcomes after allogeneic stem cell transplantation (SCT) for Hodgkin lymphoma (HL) when used as pre-transplant salvage therapy. Between 2010 and 2014, 428 adult patients underwent an allogeneic SCT for classical HL at participating centres of the European Society for Blood and Marrow Transplantation. We compared the outcomes of 210 patients who received BV prior to allogeneic SCT with that of 218 patients who did not receive BV. The median follow-up for survivors was 41 months. Patients in the BV group were more heavily pre-treated (median pre-allograft treatment lines: 4 vs. 3). The two groups were comparable in terms of disease status, performance status, comorbidities, prior autologous SCT, type of donor, conditioning and in vivo T cell depletion. In multivariate analysis, pre-allograft BV had no impact on acute graft-versus-host disease (GVHD), non-relapse mortality, cumulative incidence of relapse, progression-free survival or overall survival (OS), but significantly reduced the risk of chronic GVHD (hazard ratio = 0.64; 95% confidence interval = 0.45-0.92; P < 0.02). Older age, poor performance status, use of pre-transplant radiotherapy and active disease at SCT adversely affected OS. Patients allografted for HL after prior exposure to BV do not have a superior outcome after allogeneic SCT except for a lower risk of chronic GVHD. However, BV may improve the outlook of allogeneic SCT by helping otherwise refractory patients to achieve a more favourable disease status, facilitating allotransplant success.

Abstract
BACKGROUND To evaluate long-term outcome of myeloablative allogeneic stem cell transplantation (allo-SCT) (MAC) versus reduced-intensity allo-SCT (RIC) in patients with relapsed/refractory Hodgkin's lymphoma (HL) in recent years. PATIENTS AND METHODS A total of 312 patients (63 MAC and 249 RIC) with relapsed/refractory HL who received allo-SCT between 2006 and 2010 and were reported to the EBMT Database were included in the study. RESULTS With a median follow-up for alive patients of 56 (26-73) months, there were no significant differences in non-relapse mortality (NRM) between MAC and RIC. Relapse rate (RR) was somewhat lower in the MAC group (41% versus 52% at 24 months, P = 0.16). This lower RR translated into a marginal improvement in event-free survival (EFS) for the MAC group (48% versus 36% at 24 months, P = 0.09) with no significant differences in overall survival (73% for MAC and 62% for RIC at 24 months, P = 0.13). Multivariate analysis after adjusting for disease status at the time of allo-SCT showed that the use of MAC was of borderline statistical significance for predicting a lower RR and EFS [HR 0.7, 95% CI (0.5-1.0), P = 0.1] and [HR 0.7, 95% CI (0.5-1.0), P = 0.07], respectively, after allo-SCT. CONCLUSIONS With modern transplant practices, the NRM associated with MAC for HL has strongly decreased, resulting into non-significant improvement of EFS because of a somewhat better disease control compared with RIC transplants. The intensity of conditioning regimens should be considered when designing individual allo-SCT strategies or clinical trials in patients with relapsed/refractory HL.Copyright © The Author 2016.
