However, few studies have assessed the association between socioeconomic parameters and prognosis in Acute Myeloid Leukemia (AML), and these report conflicting results. Our monocentric study assessed the impact of socioeconomic deprivation using the validated EPICES (Evaluation of Deprivation and Inequalities in Health Examination Centers) score in a prospective cohort of intensively treated AML patients.Methods: EPICES questionnaires were given to patients receiving intensive chemotherapy for newly diagnosed AML at the Paoli Calmettes Institute between July 2012 and December 2014. Study participants were categorized as non-deprived (score <30.17), deprived (score 30.17-48.51), or very-deprived (score ≥ 48.52). The primary endpoint was Overall Survival (OS). The independence of EPICES score effects was analyzed via Cox regression with adjustment for confounding factors.Results: 209 AML patients received the questionnaire, 149 (71.3 %) patients responded. The median EPICES score was 23.6; 26.8 % and 10.1 % of patients were deprived and very deprived, respectively. OS was 23.16 months (95 %CI [17.15-33.31]). According to multivariate analysis, a very-deprived EPICES score, European Leukemia Net categories, age, smoking, and the absence of allogeneic stem cell transplantation were independent factors associated with decreased OS.Conclusion: Our results underscore the importance of integrating nonbiological factors in the prognostic stratification of AML patients. The very deprived population exhibited worse OS, confirming that socioeconomic parameters play a role in patient outcomes in AML. Very deprived patients with AML should receive specific attention and adapted clinical management

HLA-Matched Sibling versus Unrelated versus Haploidentical Related Donor Allogeneic Hematopoietic Stem Cell Transplantation for Patients Aged Over 60 Years with Acute Myeloid Leukemia: A Single-Center Donor Comparison

Haploidentical related donor (HRD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) was developed as a valid option for the treatment of acute myeloid leukemia (AML) in the absence of a matched donor. However, many investigators are reluctant to consider the use of this alternative in elderly patients, anticipating high morbidity. Here, we report a single-center comparison of HRD versus matched sibling donor (MSD) and unrelated donor (UD) allo-HSCT for patients with AML aged >= 60 years. Ninety-four patients (MSD: n = 31; UD: n = 30; HRD: n = 33) were analyzed. The median age was 65 (range, 60 to 73) years. We observed a higher cumulative incidence of grade 3 to 4 acute graft-versus-host disease (GVHD) after UD allo-HSCT (MSD versus UD versus HRD: 3% versus 33% versus 6%, respectively; P = .006). Two-year cumulative incidence of moderate or severe chronic GVHD was 17%, 27%, and 16% in the MSD, UD, and HRD groups, respectively (P = .487). No difference was observed in the 2-year cumulative incidence of relapse or nonrelapse mortality (NRM) (relapse: MSD versus UD versus HRD: 32% versus 25% versus 25%, respectively; P = .411; NRM: MSD versus UD versus HRD: 19% versus 27% versus 24%, respectively; P = .709). At 2 years, progression-free survival, overall survival, and GVHD- and relapse-free survival were 48%, 50%, and 39%, respectively, in the MSD group; 48%, 51%, and 23%, respectively, in the UD group; and 50%, 52%, and 32%, respectively, in the HRD group, without statistically significant differences between the groups. We conclude that HRD allo-HSCT is highly feasible and no less efficient than MSD or UD allo-HSCT in patients with AML aged >= 60 years. Thus, the absence of a HLA-identical donor should not limit the consideration of allo-HSCT for the treatment of AML. (C) 2018 American Society for Blood and Marrow Transplantation

Gut microbiota diversity after autologous fecal microbiota transfer in acute myeloid leukemia patients

International audienceAcute myeloid leukemia (AML) intensive chemotherapy combined with broad-spectrum antibiotics, leads to gut microbiota dysbiosis promoting pathological conditions and an increased incidence of complications. Here we report findings from a phase II single-arm, multicenter study evaluating autologous fecal microbiota transfer (AFMT) in 25 AML patients treated with intensive chemotherapy and antibiotics (ClinicalTrials.gov number: NCT02928523). The co-primary outcomes of the study are to evaluate the efficacy of AFMT in dysbiosis correction and multidrug-resistant bacteria eradication. The main secondary outcomes are to define a dysbiosis biosignature, to evaluate the effect of dysbiosis correction on patient clinical status, to assess the short and mid-term safety of AFMT in this immunocompromised population, and to evaluate the feasibility of the AFMT procedure and acceptability by the patient. Intensive induction chemotherapy induces a dramatic decrease of α-diversity indices, and a microbial dysbiosis with a significant shift of the microbial communities and domination of pro-inflammatory families. After AFMT treatment, α-diversity indices return to their initial mean levels and the similarity index shows the restoration of microbial communities. The trial meets pre-specified endpoints. AFMT appears to be safe and may be effective for gut microbiota restoration in AML patients receiving intensive chemotherapy and antibiotics, with an excellent gut microbiota reconstruction based on both richness and diversity indices at the species level
