Abstract Goal: Compare results after allogeneic HSCT for AML in CR1 in pediatric population after myeloablative conditioning regimen either based on TBI or busulfan. Patients and Methods: Retrospective analysis from French registry including all consecutive patients under 18 years of age (n=131) from Dec’1979 and Oct’2004 transplanted for AML in CR1 with either sibling (n=104) or matched unrelated donor and given either multi-fractionated TBI 12Gy and cyclophosphamide 120mg/kg (TBI-Cy) or Busulfan 16mg/kg and Cyclophosphamide 200mg/kg (BuCy200). Results were analysed according to EBMT statistical analysis guidelines i.e. OS and EFS were analyzed by KM method and Log-rank test for comparison where TRM and relapse incidence were analyzed by cumulative incidence method and Gray test for comparison. Multivariate analyses were performed using proportional hazard model for the distribution of competitive risks defined by Fine and Gray. Results: 131 patients (female: 51.5%) were included. Median age at initial diagnosis was 11y (0.5 to 17.8). Median time from diagnosis to transplantation was 4.2 months. Eighty-three patients received BuCy200 and 48 patients were transplanted after TBI-Cy. Patient subgroups were comparable for age, gender, sex mismatch, source of graft (BMT vs PBSC), donor type (geno-identical vs 10/10 matched unrelated donor vs other), cytogenetical analysis and WBC at initial diagnosis, and for donor-recipient CMV status (−/+ vs others). Both 5 year-overall and event-free survival rates appeared significantly better in BuCy200 group than in TBI-Cy group with 73.3% vs 56.1% (p=0.02) and 67+/−7% vs 38+/−9% (p=0.002), respectively. TRM incidence at day 365 was dramatically better in BuCy200 group than in TBI-Cy group with 4,7% vs 26.1% of TRM rate (p=0.002), respectively. Even though there were no statistical significant differences for both acute and chronic GVHD cumulative incidences whatever given conditioning regimen, there was a trend for obtaining lesser GVHD in BuCy200 group: day 100 grade II-IV aGVHD cumulative incidence was 13% vs 37% and 2 year extensive cGVHD was 9 vs 19% for BuCy200 and TBI-Cy group, respectively. At 5 years, there was a trend for less relapse in BuCy200 group than in TBI-Cy 16+/−3% vs 32+/−6% (p=0.09), respectively. Conclusion: This study demonstrates the superiority of BuCy200 on TBI-Cy conditioning regimen for paediatric patients presenting with AML in CR1 and undergoing allogeneic hematopoietic stem cell transplantation from either matched related or unrelated donor. These results, obtained from a larger cohort, confirm and update those published by our group in 1994. Figure 1: Overall survival Figure 1:. Overall survival

T-cell replete Haploidentical stem cell transplantation (Haplo-SCT) with Post-transplant cyclophosphamide (PT-Cy) is an emerging therapeutic option for patients with advanced relapsed or refractory lymphoma. The feasibility of this platform is supported by several retrospective studies showing a toxicity profile that is improved relative to umbilical cord blood and mismatched unrelated donor (UD) transplant and comparable to matched unrelated donor transplant. In particular, cumulative incidence of chronic graft-versus-host disease (GVHD) is reduced after Haplo-SCT relative to UD and matched related donor (MRD) transplant thanks to PT-Cy employed as GVHD prophylaxis. This achievement, together with a similar incidence of acute GVHD and disease relapse, results in a promising advantage of Haplo-SCT in terms of relapse-free/GVHD free survival. Unmet needs of the Haplo-SCT platform are represented by the persistence of a not negligible rate of non-relapse mortality, especially due to infections and disease relapse. Future efforts are warranted in order to reduce life-threatening infections and to employ Halo-SCT with PT-Cy as a platform to build new immunotherapeutic strategies.

Background: Allogeneic stem cell transplantation (alloSCT) offers cure chance for various hematologic malignancies, but graft- versus-host disease (GVHD) remains a major impediment. Anti-thymocyte globulin (ATG) is used for prophylactic T-cell depletion and GVHD prevention, but there are no clear guidelines for the optimal dosing of ATG. It is suspected that for patients with low absolute lymphocyte counts (ALCs), current weight-based dosing of ATG can be excessive, which can result in profound T-cell depletion and poor transplant outcome. Methods: The objective of the study is to evaluate the association of low preconditioning ALC with outcomes in patients undergoing matched unrelated donor (MUD) alloSCT with reduced-intensity conditioning (RIC) and ATG. We conducted a single-center retrospective longitudinal cohort study of acute leukemia and myelodysplastic syndrome patients over 18 years old undergoing alloSCT. In total, 64 patients were included and dichotomized into lower ALC and higher ALC groups with the cutoff of 500/μl on D-7. Results: Patients with preconditioning ALC <500/μl were associated with shorter overall survival (OS) and higher infectious mortality. The incidence of acute GVHD and moderate-severe chronic GVHD as well as relapse rates did not differ according to preconditioning ALC. In multivariate analyses, low preconditioning ALC was recognized as an independent adverse prognostic factor for OS. Conclusion: Patients with lower ALC are exposed to excessive dose of ATG, leading to profound T-cell depletion that results in higher infectious mortality and shorter OS. Our results call for the implementation of more creative dosing regimens for patients with low preconditioning ALC.
