Abstract Abstract 1198 Poster Board I-220 Background: Unrelated cord blood transplantation is an alternative option to treat patients with high risk hematologic malignancies in the absence of an HLA identical donor. Results of UCBT in patients with MDS or secondary leukaemia (sAML) have been scarcely published. Method: We performed a survey to identify predictors of outcomes in a large cohort of 108 adults with MDS or sAML reported to Eurocord-Promise data bases (62 centres in 17 countries in Europe) and transplanted with an UCBT from 1998 to 2007. Sixty-seven patients were transplanted for sAML (secondary to MDS in 42 cases) and 41 for MDS. Worst status before UCBT for MDS was RA in 4, RAEB1 in 10, RAEB2 in 14, CMML or RAEBt in 9, unclassified in 4 patients. IPSS classification at transplantation was low, intermediate 1, intermediate 2, high or missing in 8, 12, 7, 6 and 8 patients, respectively. For patients with sAML, 48% were transplanted in CR1 at UCBT. Median age at UCBT was 43 years (from 18 to 72 years). Median time from diagnosis to UCBT was 10 months. Transplant characteristics: 77 patients received a single and 31 a double UCBT. UCB grafts had ≥ 2/6 HLA mismatched in 60 % of cases. Myeloablative conditioning regimen (MAC) was given to 57 patients whereas 51 patients received a reduced intensity conditioning regimen (RIC). GVHD prophylaxis consisted in CSA+MMF in 52, CSA+steroids in 43 and other combinations in 13 patients. Median number of collected nucleated cells was 3.4 for single and 4.6 × 107/kg for double UCBT. Median follow-up was 25 months. Results: cumulative incidence (CI) of neutrophil recovery at day 60 was 82±4% with a median time to achieve more than 500 ANC/mm3 of 23 days. Neutrophil recovery was independently associated with number of CD34+ cells/kg (> 1.1 × 105, Hazard Ratio (HR), 1.79; P= .02) and advanced disease status (intermediate 2 or high MDS and sAML not in CR; HR, 1.92; P= .007). CI of grade II-IV acute GVHD at day 100 and chronic GVHD at 2 years were 26±4% (II n=18, III n=6, IV n =6) and 42%±8, respectively. Two-year non-relapse mortality was significantly higher after MAC (62% vs. 34%, p=0.009). In counterpart, 2-year relapse rate was higher after RIC (14% vs 29%, p=0.02). Two-year DFS and OS were 30 and 34%, respectively. In univariate analysis, among patient-, disease- and transplant- factors studied only patients with high risk disease at maximal pre-transplant stage or transplanted > 18 months after diagnosis had significant poorer DFS (disease risk: 49% vs. 22%; time: 35% vs. 15%). However, in multivariate analysis, the only factor associated with decreased DFS was advanced disease (HR: 2.05; p= .01). Conclusion: These data indicate that UCBT is an acceptable alternative option to treat adults with high risk MDS or sAML without a HLA-matched related or unrelated bone marrow donor. Controlled disease at time of transplantation improves outcome. More investigations are needed to compare these results with outcomes after other stem cell sources from unrelated HSCT donor. Disclosures: No relevant conflicts of interest to declare.

Abstract Background: C-reactive protein (CRP) is an acute-phase protein and its serum level rises in response to inflammation. There have been some reports about the relationship between the serum CRP level before allogeneic hematopoietic stem cell transplantation (HSCT) and transplant outcomes. This study particularly evaluated the impact of pre-transplant CRP on the outcome in patients who received a single-unit unrelated cord blood transplantation (UCBT) for hematologic malignancies. Patients and methods: Adult patients receiving UCBT as first HSCT for hematologic malignancies between April 2009 and April 2016 at Kanagawa Cancer Center were retrospectively analyzed in this study. Serum CRP was measured by a latex agglutination assay (normal range 0.0-0.3 mg /dl). The time of measurement was within a few days before the conditioning procedure. Patients were divided into 2 groups according to the serum CRP levels (normal CRP group [≤0.03 mg/dl] and high CRP group [> 0.03 mg/dl)]). A total of 80 patients (pts) included 36 pts with acute myeloid leukemia (AML), 27 pts with acute lymphoid leukemia (ALL), 13 pts with myelodysplastic syndrome (MDS), and 4 pts with others. The median age was 59 years (range, 20-68 years). There were 45 males and 35 females. A disease risk at transplantation indicated a standard risk in 47 pts and a high risk in 33 pts. Myeloablative conditioning (MAC) was employed for 25 pts and reduced intensity conditioning (RIC) was for 55 pts. Data were analyzed with EZR statistical software. Results: The median level of serum CRP at pre-transplant was 0.17 mg/dl (range: 0.01-12.93). No. of patients in normal and high CRP levels was 56 pts and 24 pts, respectively. Disease high risk was significantly associated with a high level of serum CRP. Other pre-transplant factors such as age, gender, diagnosis, comorbidity index, and serum ferritin levels were not related with serum CRP levels. The high incidence of gradeⅡ-Ⅳacute GVHD was significantly associated with high CRP group compared to normal CRP group (55% vs. 19%, p = 0.001). After a median follow-up of 16 months (range: 1-86 months), 3-year overall survival (OS) was 62%. The cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) at 3 years was 26% and 14%, respectively. According to univariate analysis, factors associated with worse 3-year OS included disease high risk at transplantation (vs. low risk; 49% vs. 70%, p = 0.025) and high CRP levels (vs. normal CRP levels; 28% vs. 77%, p < 0.001). Higher 3-year CIR was significantly correlated with high CRP levels (vs. normal CRP levels; 46% vs. 18%, P = 0.009). Adverse factors for NRM was high scores (≥3) of HCT-CI (vs. low scores (≤2) of HCT-CI; 25% vs. 5%, p=0.029). Multivariate analysis showed that high CRP levels (hazard ratio [HR], 4.13; 95% confidence interval [CI], 1.76-9.63; p = 0.001) was an independent determinant of 3-year OS. Prognostic factors related with CIR and NRM was high CRP levels (HR, 2.63; 95%CI, 0.96-7.21; p = 0.059) and high scores of HCT-CI (HR, 4.25; 95%CI, 0.89-20.29; p = 0.069) respectively, but those difference did not reach statistical significance. Conclusions: Pre-transplant serum CRP might be a useful biomarker for predicting the transplant outcome and the development of acute GVHD following UCBT.
