Abstract Abstract 3421 Bone marrow transplantation (BMT) from an HLA-matched family donor (MFD) is the treatment of choice for severe aplastic anemia (SAA) in children. For children without an MFD, immunosuppressive therapy (IST) with a combination of antithymocyte globulin and cyclosporine has been successful. However, this treatment approach is based on the results of comparative studies between these therapies conducted in the 1980s, and the outcomes of both BMT and IST have improved markedly over the past three decades. Therefore, updated evidence for treatment decisions in pediatric SAA is required. In the present study, we compared the outcomes of children with SAA who received IST (subjects enrolled in the prospective multicenter trials of IST conducted by the Japan Childhood Aplastic Anemia Study Group) or BMT from an MFD (subjects registered in the Transplant Registry Unified Management Program conducted by the Japan Society for Hematopoietic Cell Transplantation). The influence of potential risk factors on overall survival (OS) and failure-free survival (FFS) was assessed according to first-line treatment, time period of treatment (1992–1999 and 2000–2009), age and other variables related to each treatment. FFS was defined as survival with treatment response. Death, primary or secondary graft failure, relapse and secondary malignancy were considered treatment failures in patients who received BMT. Death, relapse, disease progression requiring stem cell transplantation from an alternative donor or 2nd IST, clonal evolution and evolution to paroxysmal nocturnal hemoglobinuria were considered treatment failures in patients who received IST. Between 1992 and 2009, 599 children with SAA younger than 17 years received BMT from an MFD (n=213) or IST (n=386) as first-line treatment. While the OS did not differ between patients receiving IST and BMT (88±2% vs. 90±2% at 15 years), FFS was significantly inferior in patients receiving IST as compared to those receiving BMT (54±3% vs. 84±3% at 15 years, P<0.0001). There was no significant improvement in outcomes over the two time periods; OS and FFS at 10 years in 1992–1999 vs. 2000–2009 were 87±2% vs. 93±2% and 66±3% vs. 67±3%, respectively. On multivariate analysis, age <10 years was identified as a favorable factor for OS (P=0.007) and choice of first-line IST was the only unfavorable factor for FFS (P<0.0001). These updated data support the current algorithm for treatment decisions, which recommends BMT when an MFD is available. Disclosures: No relevant conflicts of interest to declare.

Abstract Treatment of severe aplastic anemia has improved significantly over the past 4 decades. This review will summarize the key areas of progress in the use of allogeneic hematopoietic cell transplantation and nontransplant immunosuppressive therapy (IST) for the treatment of aplastic anemia and then summarize the recommendations for first-line treatment. Based on recent data, we argue that guidelines for the initial treatment of patients with newly diagnosed severe aplastic anemia require revision. At the time of diagnosis, before beginning treatment, HLA typing should be done to identify a marrow donor among family members or in the unrelated donor registries, and a marrow transplant should be considered first-line therapy. The priority order of donor source for bone marrow transplantation is: (1) HLA-identical sibling, (2) HLA-matched unrelated donor, and (3) HLA-haploidentical donor if an HLA-matched unrelated donor is not rapidly available. Each of these donor marrow sources may be preferable to nontransplant IST. We make this recommendation because of the long-term persistent risk for disease relapse and secondary myelodysplastic syndrome or acute myeloid leukemia with the use of nontransplant IST for patients with aplastic anemia. In contrast, marrow transplantation is associated with high cure rates of aplastic anemia and a relatively low risk for graft-versus-host disease, with many patients now living for decades without the risk for disease recurrence or the development of clonal disorders. Implementation of this first-line treatment strategy will provide patients with severe aplastic anemia the best chance of long-term disease-free survival.

e16557 Background: EpCAM is a tumor associated antigen which is frequently expressed in ovarian cancer. Recently, an autoantibody (AAB) against EpCAM has been identified in ovarian cancer patients. Autoantibodies are immunogene factors and might be of prognostic importance. We showed that disseminated tumor cells (DTC) in bone marrow carry the EpCAM antigen on their surface and correlate with poorer progression free survival (PFS). Here, we evaluated whether EpCAM-AABs have an impact on clinical parameters or the presence of DTC in ovarian cancer patients. Methods: EpCAM-AABs were determined in sera of 28 healthy voluntary age matched females and 62 patients with primary epithelial ovarian cancer before and after platinum-based chemotherapy using a recombinant EpCAM-epitope for antibody- detection by ELISA technique. Mean follow up time was 13 months. DTC in BM were detected by immunocytochemistry applying the pan cytokeratin antibody A45-B/B3. All samples exceeding the mean antibody titer of healthy controls plus 2 standard deviations were considered positive. Results: The antibody titer of healthy controls was 0.061 + 0.015. Using a cut-off value of 0.091, we found 9/62 (15%) ovarian cancer patients to be positive for EpCAM-AABs after first-line treatment. Interestingly, no positive AAB-titers were seen before therapy. Using the paired T-Test, we noted a significant posttherapeutic increase of AABs (CI 0.95, p < 0.0001). Analysis of PFS, FIGO stage, resection status, grading, age, sensitivity to platinum based chemotherapy and DTC did not reveal significant associations with positive EpCAM-AAB titers. Conclusions: The clinical course of ovarian cancer patients and the prevalence of DTC were not altered by EpCAM-AABs. Interestingly, we observed an increase of antibody-levels after first-line treatment. For further validation, we intend to extend our patient collective. In future, it might also be interesting to investigate the impact of AABs on response to targeted therapies against EpCAM. No significant financial relationships to disclose.
