Abstract
Late relapse (LR) after allogeneic hematopoietic stem cell transplantation (AHSCT) for acute leukemia is a rare event (nearly 4.5%) and raises the questions of prognosis and outcome after salvage therapy. We performed a retrospective multicentric study between January 1, 2010 and December 31, 2016, considering data from the French national retrospective register ProMISe (SFGM-TC (French Society for Bone Marrow Transplantation and Cellular Therapy)). We included patients presenting LR, defined as a relapse occurring at least two years after AHSCT. We used the Cox model to identify prognosis factors associated with LR. During the study period, 7,582 AHSCT were performed in 29 centers and 33.8% of patients relapsed. Among them, 319 (12.4%) were considered as LR, representing an incidence of 4.2% from the entire cohort. The full dataset was available for 290 patients, including 250 (86.2%) with acute myeloid leukemia, and 40 (13.8%) with acute lymphoid leukemia. Median delay from AHSCT to LR was 38.2 months (29.2-49.7) and 27.2% of patients had extramedullary involvement at LR (17.2% exclusively and 10% associated with medullary involvement). One-third of patients had persistent full donor chimerism at LR. Median overall survival (OS) after LR was 19.9 months (5.6-46.4). The most common salvage therapy was induction regimen (55.5%), with complete remission being obtained for 50.7%. Ninety-four patients (38.5%) underwent a second AHSCT, with a median OS of 20.4 months (7.1-49.1). Non-relapse mortality after second AHSCT was 18.2%. We identified in the Cox model some of the associated factors with delay of LR: the disease status not in first complete remission at first HSCT (odds ratio (OR) 1.31, 1.04-1.64, p=0.02) and the use of post-transplant cyclophosphamide (OR 2.23, 1.21-4.14, p=0.01). Chronic GVHD appeared to be a protective factor (OR 0.64, 0.42-0.96, p=0.04). Prognosis of LR is better than early relapses, with a median OS after LR of 19.9 months. Salvage therapy associated with a second AHSCT improves outcome and is feasible, without creating excess toxicity.

Abstract
Subsequent neoplasms (SNs) compromise long-term survivors after hematopoietic cell transplantion. We performed a retrospective analysis of SNs in a cohort of 10358 recipients of umbilical cord blood transplantation (UCBT) reported to Eurocord/EBMT registries from 1988 to 2018. A total of 233 patients developed SNs. Median age at UCBT was 31 years (y) (0.3-69), and 84 were pediatric patients. Indications for UCBT were malignant hematological diseases in 199 patients (85%). Three groups of SNs were observed. Post-transplant lymphoproliferative disorders (PTLD) were reported in 145 patients in a median of 4 months after UCBT. Of these, 9/145 patients died from relapse, 83/145 from PTLD, and 24/145 from transplant-related causes. At last follow-up, 29/145 were alive; 5y-overall survival (OS) after PTLD diagnosis was 21±3%. Acute leukemia / myelodysplasia (AL/MDS) was diagnosed in 23 patients in a median of 28 months after UCBT and included 3 donor-cell AL. Four of 23 patients died from relapse of primary disease, 8/23 from progression of SNs, and 4/23 from TRM. Seven patients were alive at last follow-up; 5y-OS after AL/MDS diagnosis was 36±10%. Solid tumors (ST) were reported in 65 patients in a median of 54 months after UCBT. Most common tumor sites were lung, thyroid, bone and soft tissue. A total of 33/65 patients died (26 due to ST, 6 to relapse of primary disease, 1 cause missing). At last follow-up, 32/65 patients were alive; 5y-OS after the diagnosis of ST was 51±6%. In conclusion, despite their poor outcomes, SNs that occur after UCBT are extremely rare. Identification of associated risk factors and early detection may help to improve OS.

Abstract
Therapy-related myelodysplastic syndrome (t-MDS) after autologous stem-cell transplantation (ASCT) is a rare complication with no curative option. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be considered for eligible patients and has been understudied in t-MDS. We report 47 consecutive patients with t-MDS after an ASCT who underwent allo-HSCT with a median age of 58 years (range: 30-71) at transplantation and a median follow-up of 22 months (range: 0.7-107). The median overall survival (OS) was 6.9 months (95% confidence interval, 0-19). OS rates were 45% (29-60%) and 30% (15-45%) at 1 and 3 years after transplantation, respectively. On univariate analysis prior therapy for t-MDS before allo-HSCT (p=0.02) and mismatched donors (p=0.004) were associated with poor OS. Three-year non-relapse mortality (NRM) and relapse rates were 44% (25-63%) and 41% (22-61%), respectively. Mismatched donors (p<0.001) were associated with higher NRM and a high-risk MDS (p=0.008) with a higher relapse risk. On multivariate analysis HLA mismatch was associated with higher NRM (HR 6.21; 95% CI 1.63-23.62; p=0.007). In conclusion, our results suggest that one third of the patients who develop t-MDS after an ASCT for lymphoma are cured after an allo-HSCT. The use of mismatched donors with standard GVHD prophylaxis should be avoided in such indication for allo-HSCT. It will be worth to see if the implementation of CY post-transplantation will improve the outcome with mismatched donors.

Abstract
Long-term survivors after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are at high risk for treatment-related adverse events, that may worsen physical capacity and may induce fatigue and disability. The aims of this prospective study were to evaluate exercise capacity in allotransplant survivors and its relationship with fatigue and disability. Patient-reported outcomes and exercise capacity were evaluated in 71 non-relapse patients 1 year after allo-HSCT, using validated questionnaires, cardiopulmonary exercise testing (CPET) with measure of peak oxygen uptake (peakVO(2)) and deconditioning, pulmonary function testing, echocardiography and 6-min walk test. A high proportion (75.4%) of allo-HSCT survivors showed abnormal cardiopulmonary exercise testing parameters as compared to predicted normal values, including 49.3% patients who exhibited moderate to severe impairment in exercise capacity and 37.7% patients with physical deconditioning. PeakVO(2) values were not accurately predicted by 6-min walk distances (r = 0.53). Disability and fatigue were strongly associated with decreased peakVO(2) values (p = 0.002 and p = 0.008, respectively). Exercise capacity was reduced in most allo-HSCT long-term survivors. Because reduced exercise capacity was associated with fatigue, disability and a decrease in quality of life, cardiopulmonary exercise testing should be performed in every patient who reports fatigue and disability.

Abstract
Limited information is available regarding the incidence and features of lymphocyte expansions after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Large granular lymphocytes (LGL) expansions have been reported after bone marrow or peripheral blood, but not after unrelated cord blood (UCB) allo-HSCT, associated with indolent clinical courses and favorable outcomes. Here, we considered 85 recipients of UCB allo-HSCT to more broadly define the impact of lymphocytosis, not limited to LGL. Sustained lymphocytosis was observed in 21 (25%) patients at a median onset of 12.6 months and with a median duration of 12 months. Immunophenotypic analysis showed predominantly CD8+ T and/or polyclonal B-cell expansions. Three patients only had monoclonal T-cell expansion. CMV reactivation was significantly more frequent in the group of patients with lymphocytosis (76% vs 28%, P=0.0001), but was not associated with survival. Conversely, 2-year disease-free survival and overall survival were significantly higher for lymphocytosis patients (85% vs 55%, P=0.01 and 85% vs 63%, P=0.03, respectively). In conclusion, expansion of T or B lymphocytes after UCB allo-HSCT in adults is not a rare event. Although occurring relatively late after transplant, this feature is predictive of a better outcome for the patients.

Abstract
Late complications (LC) and quality of life (QOL) were analyzed in 110 adult patients who underwent reduced-intensity conditioning (RIC) allogeneic stem cell transplantation (allo-SCT) and were alive for more than 2 years after allo-SCT. Overall survival of these patients was 93% (95% confidence interval [CI], 88% to 99%) and 81% (95% CI, 71% to 94%) at 5 and 10 years, respectively. The primary cause of death was a recurrence of primary malignancy. With a median follow-up of 4.6 years (range, 2 to 12.1), chronic graft-versus-host disease (cGVHD) was the most prevalent late effect, with a cumulative incidence of 66% (95% CI, 57% to 74%) at 10 years. Cardiovascular complications were the most prevalent LC with a cumulative incidence of 47% (95% CI, 35% to 59%), followed by pulmonary complications with a cumulative incidence of 33% (95% CI, 21% to 46%) and renal impairment with a cumulative incidence of 34% (95% CI, 25% to 43%) at 10 years. Secondary malignancies occurred with a cumulative incidence of 11% (95% CI, 5% to 20%) at 10 years. In this series, 61 patients (55%) responded to QOL survey. With the use of European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 and Functional Assessment of Cancer Therapy-Bone Marrow Transplant questionnaires, most of the patients reported good to excellent QOL and patients with cGVHD had significantly lower QOL than patients without cGVHD. In conclusion, QOL after RIC is comparable to that seen after myeloablative conditioning, while the natural history of LC after RIC appears to be different from that described in the standard myeloablative setting, warranting further research in this field.

Abstract
Importance: Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post-lung transplant bronchiolitis obliterans syndrome. Objective: To evaluate if the early administration of azithromycin can improve airflow decline-free survival after allogeneic HSCT. Design, Setting, and Participants: The ALLOZITHRO parallel-group trial conducted in 19 French academic transplant centers and involving participants who were at least 16 years old, had undergone allogeneic HSCT for a hematological malignancy, and had available pretransplant pulmonary function test results. Enrollment was from February 2014 to August 2015 with follow-up through April 26, 2017. Interventions: Patients were randomly assigned to receive 3 times a week either 250 mg of azithromycin (n=243) or placebo (n=237) for 2 years, starting at the time of the conditioning regimen. Main Outcomes and Measures: The primary efficacy end point was airflow decline-free survival at 2 years after randomization. Main secondary end points were overall survival and bronchiolitis obliterans syndrome at 2 years. Results: Thirteen months after enrollment, the independent data and safety monitoring board detected an unanticipated imbalance across blinded groups in the number of hematological relapses, and the treatment was stopped December 26, 2016. Among 480 randomized participants, 465 (97%) were included in the modified intention-to-treat analysis (mean age, 52 [SD, 14] years; 75 women [35%]). At the time of data cutoff, 104 patients (22%; 54 azithromycin vs 50 placebo) had experienced an airflow decline; 138 patients (30%) died (78 azithromycin vs 60 placebo). Two-year airflow decline-free survival was 32.8% (95% CI, 25.9%-41.7%) with azithromycin and 41.3% (95% CI, 34.1%-50.1%) with placebo (unadjusted hazard ratio [HR], 1.3; 95% CI, 1.02-1.70; P=.03). Of the 22 patients (5%) who experienced bronchiolitis obliterans syndrome, 15 (6%) were in the azithromycin group and 7 (3%) in the placebo group (P=.08). The azithromycin group had increased mortality, with a 2-year survival of 56.6% (95% CI, 50.2%-63.7%) vs 70.1% (95% CI, 64.2%-76.5%) in the placebo group (unadjusted HR, 1.5; 95% CI, 1.1-2.0; P=.02). In a post hoc analysis, the 2-year cumulative incidence of hematological relapse was 33.5% (95% CI, 27.3%-39.7%) with azithromycin vs 22.3% (95% CI, 16.4%-28.2%) with placebo (unadjusted cause-specific HR, 1.7; 95% CI, 1.2-2.4; P=.002). Conclusions and Relevance: Among patients undergoing allogeneic HSCT for hematological malignancy, early administration of azithromycin resulted in worse airflow decline-free survival than did placebo; these findings are limited by early trial termination. The potential for harm related to relapse requires further investigation. Trial Registration: clinicaltrials.gov Identifier: NCT01959100.
