Abstract BACKRGOUND. Non-relapse mortality (NRM) is the first cause of treatment failure after unrelated cord blood transplantation (UCBT) following myeloablative conditioning (MAC). In the last decade, reduced-intensity conditionings (RIC) for UCBT have been developed with the aim of reducing NRM and allowing older patients and those with medical comorbidities to benefit from UCBT. The aim of our retrospective registry study was to compare outcomes of acute leukemia (AL) adult patients given UCBT after either RIC or MAC regimens. Regimens were classified as MAC or RIC based on EBMT criteria. PATIENTS AND METHODS. Data from 1352 adult (> 18 yrs) patients with AL (acute myeloid leukemia [AML; n=894] or acute lymphoblastic leukemia [ALL; n=458]) given a first single or double UCBT from 2004 to 2013 at EBMT-affiliated centers were included in this retrospective study. RESULTS. 518 patients were given UCB after RIC, while 834 patients were administered MAC. The most frequently used conditioning regimens combined either TBI, cyclophosphamide and Flu (TCF regimen, given in 22% of MAC vs 75% of RIC recipients, P<0.001), or thiotepa, Bu and Flu (TBF, given in 32% of MAC vs 6% of RIC recipients, P<0.001). In comparison to MAC recipients, RIC recipients were almost 2 decades older (median age 52.5 vs 33.7 yrs, P<0.001), were more often transplanted for AML (80% vs 57%, P=0.001), received more frequently 2 cord blood units (61 vs 32%, P<0.001), received more frequently units with > or = 2 HLA-mismatches (69% vs 58%, P<0.001), received more TNC (median 3.5x10E7 vs 2.9x10E7, P<0.001), and received less frequently ATG in the conditioning (23% versus 57%). Disease status at UCBT was comparable in both groups (51% of patients in CR1 and 17% >CR). Median follow-up for survivors was 25 months. In univariate analyses, in comparison to patients given MAC, RIC recipients had a similar rate of neutrophil engraftment (89.5 vs 89%, P=0.7), and a similar incidence of grade II-IV acute (34% vs 29%, P=0.1) and chronic (22% vs 26%, P= 0.22) GVHD. In contrast, at 2-yr, RIC recipients had a higher incidence of disease relapse (41 vs 24%, P<0.001) but a lower NRM (19 vs 37%, P<0.001), translating to similar leukemia-free survival (LFS, 40% vs 38%, P=0.6) but better overall survival (OS, 47 vs 42%, P=0.01) than MAC recipients (Figure 1). Further, among ALL patients, the use of TCF regimen (n=159) was associated lower NRM (21 vs 40% at 2-yr, P<0.001), lower relapse incidence (24 vs 34%, P=0.07), and better OS (63 vs 34%, P<0.001) and LFS (55 vs 27%, P<0.001). We performed separate multivariate analyses (MVA) for patients with AML and ALL. In MVA for AML patients, the use of RIC regimen was associated with a higher incidence of relapse (HR=1.6, P=0.005) but a suggestion for lower NRM (HR=0.7, P=0.1) translating to similar OS (HR=1.0, P=0.9) and LFS (HR=1.1, P=0.3). Similarly, in MVA for ALL patients, the use of RIC regimen was associated with a higher incidence of relapse (HR=2.0, P=0.002) but a lower NRM (HR=0.6, P=0.04) translating to similar OS (HR=0.8, P=0.2) and LFS (HR=1.1, P=0.5). Further, interestingly, conditioning with TCF-based regimen was associated with a lower incidence of relapse (HR=0.5, P=0.004) translating into better OS (HR=0.6, P=0.013) and LFS (HR 0.6, P=0.002) in ALL patients in MVA adjusted for conditioning intensity (RIC vs MAC). CONCLUSIONS. These data suggest that LFS and OS might be as good with RIC than with MAC in adults AL patients offered UCBT. These observations could serve as basis for future prospective randomized studies. Figure 1. Unadjusted UCBT outcomes in patients transplanted following RIC versus MAC. Figure 1.

AbstractWe report the results of unrelated cord blood transplantation (CBT) for 13 adult patients with advanced myelodysplastic syndrome (MDS). The median age was 40 years, the median weight was 51 kg, and the median number of infused nucleated cells was 2.43 × 107/kg. Twelve patients had myeloid reconstitution, and the median time to more than 0.5 × 109/L (5 × 108/L) absolute neutrophil count was 22.5 days. A self-sustained platelet count more than 50 × 109/L was achieved in 11 patients at a median time of 49 days. Acute graft versus host disease (GVHD) occurred in 9 of 12 evaluable patients and chronic GVHD in 8 of 11 evaluable patients. Ten patients are alive and free of disease at between 171 and 1558 days after transplantation. The probability of disease-free survival at 2 years was 76.2%. These results suggest that adult advanced MDS patients without suitable related or unrelated bone marrow donors should be considered as candidates for CBT.
