Our findings suggest that haploSCT as second AHSCT is feasible and potentially curative. Nevertheless, recent studies from the Acute Leukemia Working Party (ALWP) of the European Society for Blood and Marrow Transplantation (EBMT) could only show a trend for a lower RI among patients with high-risk acute myeloid leukemia after haplo-SCT in comparison to identical sibling transplants [11, 12]. Myeloablative conditioning regimens (MAC) were defined as including total body irradiation (TBI) > 8 Gy, or busulfan > 8 mg/kg, or more than one alkylating agent as per EBMT criteria [22].
Longer OS after relapse was achieved in particular by patients both in CR at haplo-SCT and relapsing more than 5 months after transplant (1-year OS 33%). METHODS: Among 1652 transplants performed for …

In multivariable analysis (MVA), comorbidity index (HCT-CI) and detectable donor-specific anti-HLA antibodies (DSA) prior to second transplant were significantly associated with worse outcomes.

In our current study, the intensity of conditioning regimen did not affect RI neither in ALL nor in AML. One explanation could be the slightly higher incidence of cGvHD, which is usually associated with GvL effects, among patients receiving PB (Additional file 4: Table S4, also shown by Bashey and colleagues [40]).

Killer cell immunoglobulin-like receptor ligand mismatching and outcome after haploidentical transplantation with post-transplant cyclophosphamide.
A possible explanation could be the higher number of ALL patients in active disease at time of transplant, a well-known factor associated with EMR [42,43,44,45]. BACKGROUND: As information on incidence, risk factors, and outcome of acute leukemia (AL) relapse after unmanipulated haploidentical stem cell transplantation (haplo-SCT) is scarce, a retrospective registry study was performed by the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation.

Data for this retrospective multicenter analysis were provided and approved by the ALWP of the EBMT registry. In the haplo-SCT setting, major human leukocyte antigen (HLA) mismatches between donor cells and recipient leukemic cells may theoretically serve as potential targets for a strong allogeneic graft vs leukemia (GVL) effect.

As part of registry-based study limitations, we were not able to study the impact of pre-transplant measurable residual disease on ALL relapse. As ALL and AML differ in biology, risk classification, induction treatment, and outcomes including relapse rates [6, 24], and also because of significant differences in patients’ characteristics (Table 1), we analyzed these two populations separately.

2008;14:641–50. It is well established that patients with acute leukemia relapsing after a first allograft have a poor prognosis with a survival of only few months [48, 49]. Two patients died from GvHD (1.1 %), while 3 (1.5%) from other transplant-related causes.
OS after relapse was defined as time from date of relapse and death from all causes.
relapse/progression was 56% (95% CI, 45% to 67%), and 1-year nonrelapse mortality (NRM) was 21% (95% CI, 13% to 29%). Data are entered, managed, and maintained in a central database with internet access; each EBMT center is represented in this database. Cunningham I. Extramedullary sites of leukemia relapse after transplant. The datasets used and/or analyzed during the current study are available from the corresponding author on reasonable request. | Quality control measures included several independent systems: confirmation of validity of the entered data by the reporting team, selective comparison of the survey data with minimum essential data A (MED-A) data sets in the EBMT registry database, cross-checking with the National Registries, and regular in-house and external data audits. | Bone Marrow Transplant. Characteristics of relapsed patients are described in Additional file 2: Table S2. In summary, within the limitations of a retrospective registry study, this analysis underscores the importance of remission of disease at time of haplo-SCT and coordinated timing of transplants, aiming in both lowering relapse incidence and increasing survival among those patients who develop relapse anyway.
