Abstract Allogeneic stem cell transplantation (allo HCT) is a curative treatment for follicular lymphoma, but is hampered by a relatively high treatment-related mortality and by difficulties in identifying high-risk groups for whom transplant is warranted. Results with myeloablative conditioning have improved, but the field has shifted largely to reduced-intensity conditioning and non-myeloablative transplantation, though morbidity and mortality are also substantial. Some groups have investigated T cell–depleted transplantation, which results in a low rate of chronic graft-versus-host disease (GVHD) and, in most studies, excellent rates of disease control. Overall, outcome after alloHCT for follicular lymphoma correlates more with disease status, with performance status and with comorbidities than with any particular conditioning regimen used. For patients with chemotherapy-sensitive disease, the treatment-related mortality has stabilized in the 15% to 20% range and, depending on the method of GVHD prophylaxis and the donor type, there is an additional 20% to 60% incidence of chronic GVHD. For patients with chemotherapy-refractory disease, both treatment-related mortality and recurrence rates are much higher, but their prognosis is dismal with other treatments and some may be cured, particularly with myeloablative transplants. Ongoing studies focus on improving conditioning regimens, on prevention of disease recurrence and on decreasing chronic GVHD.

Abstract Abstract 1180 Poster Board I-202 Benjamin Esterni, Didier Blaise Background: Allogeneic stem cell transplantation (ALLO) is the only curative therapy for many hematological malignancies. For many of these diseases, the median age at diagnosis is around the sixth decade of life, precluding myeloablative ALLO (MAC-ALLO). RIC-ALLO is less toxic and it has been performed in elderly pts, mainly affected by acute leukemia. Finally, comorbidities index seem to predict treatment related mortality (TRM) and overall survival (OS). Patients and methods: From 2001 and 2008, 67 pts older than 60 years (median age 63 y, range 60-70) received RIC-ALLO. Diseases were: acute myeloid leukemia 45%, multiple myeloma 18%, chronic lymphocytic leukemia 12%, non-Hodgkin lymphoma 10%, myelodysplasia 6%, plasmacellular leukemia 3%, others 6%. Disease status at RIC-ALLO was: complete remission 54%, partial remission 16%, and active disease 30%. RIC consisted of fludarabine-based with thymoglobulin 64%, or low-dose TBI-based 36%. Donors were: HLAid sibling 73%, matched unrelated 21%, and cord blood 6%. Previous autologous transplant was performed in 59% of pts. The median number of CD34+ and CD3+ cells infused was 5 (range 1-9.4) and 296 (range 84-704), respectively. Karnofski score was 60-80% in 25% and 90-100% in 75%; HCT-CI was 0 in 33%, 1-2 in 33%, and more than 3 in 34%; PAM score was 8-16 in 9%, 17-33 in 65%, 24-30 in 22%, and more than 31 in 3%; EBMT score was 2 in 22%, 3 in 36%, 4 in 28%, more than 5 in 12%. Results: The median follow-up was 22 months. The 2-y OS and PFS were 66.8% (IC95 [55.5-80.4]) and 52.4% (IC95 [39.5-69.5]), respectively. Grade II-IV acute graft versus host disease (aGVHD) and chronic GVHD (cGVHD) incidence were 49% and 43%, respectively. Early infections were fever of unknown origin in 42% of pts, bacterial infection in 6 cases, pneumonia in 8, and viral infections in 14. The early infection-related mortality was null. Late infections were bacterial in 3 cases, pneumonia in 1, viral infections in 6, and candidemia in 1. Seven pts died from late infective complications. Overall, the cause of death was toxicities in 18 pts and disease progression in 6 pts. The 100-d and 1-y TRM were 6.35% (IC95 [0.278-12.4]) and 24.2% (IC95 [12.9-35.4]), respectively. In univariate analysis, HCT-CI, EBMT score, and PAM score did not influence TRM or OS. Furthermore, age (60-65 vs 66-70) was not related to TRM. Conclusions: The aim of this retrospective study was to verify if TRM was excessively high in elderly pts, affected from several haematological diseases and receiving ALLO from different donors and after different RIC. A secondary objective was to evaluate if several comorbidities index could predict TRM and OS. This heterogeneity should be regarded as a more realistic view of general population. TRM was acceptable and not different when compared to younger pts as reported in literature. Furthermore, neither comorbidities index nor age help segregate a group of pts with different TRM.

Abstract Forty patients with relapsed or refractory Hodgkin’s disease (HD) underwent allogeneic stem cell transplantation (allo-SCT) following a fludarabine-based conditioning regimen from an HLA-identical sibling (n=20) or a matched unrelated donor (n=20). The median age was 31 years (range 18-58). The median number of chemotherapy regimens received prior to allo-SCT was five (range 2-9). Thirty (75%) and thirty (75%) patients had received prior radiotherapy or a prior autologous SCT, respectively. The median time to progression after autologous SCT was nine months (3–52). Disease status at SCT was refractory relapse (n=14) or sensitive relapse (n=26). The conditioning regimens employed were fludarabine (25 mg/m sq IV x 5 days)-cyclophosphamide (1 g/m sq IV x 3 days) ± antithymocyte globulin (30 mg/kg IV x 3 days) (FC±ATG) (n=14), a less intensive regimen, and fludarabine (25 mg/m sq IV x 5 days) -melphalan (70 mg/m sq IV x 2 days) (FM) (n=26), a more intensive one. The two groups had similar demographics and prognostic factors. Chimerism studies indicated 100% donor-derived engraftment in 26/26 (100%) FM patients and in 9/13 (69%) evaluable FC±ATG patients. Day 100 and cumulative (18-month) transplant-related mortality (TRM) were 5 % and 22%, respectively for the whole group. There was a nonsignificant trend towards a lower cumulative TRM in the FM group (18% vs. 30% at 18 months, p=0.2). The cumulative incidence of acute (grade II-IV) GVHD was 38%. The cumulative incidence of chronic GVHD at 18 months was 69%. There was a trend for a lower relapse rate after the occurrence of GVHD, however, this was not statistically significant (hazard ratio 0.8; p= 0.6). Progression rates were similar in the FM and FC patients (53% vs. 57% respectively at 18 months, p=0.4). However, disease progression occurred later in FM patients (range 2–34 months) than in FC patients (range 0.7–13 months). In addition, with comparable follow-up time after progression, the FM group experienced a lower death rate after progression. Twenty-four patients (60%) are alive (fourteen in complete remission) with a median follow-up of 13 months (4–78). Sixteen patients expired (TRM n=8, disease progression n=8). FM patients had significantly better overall survival (73% vs. 39% at 18 months; p=0.03), and a trend towards better progression-free survival (37% vs. 21% at 18 months; p=0.2). We conclude that allo-SCT with fludarabine-based, less intensive conditioning from matched related and unrelated donors are feasible in high-risk HD patients with a low TRM. The intensity of the preparative regimen affects survival.

Abstract It has been postulated that B cells functioning as antigen-presenting cells may have an important role in the pathogenesis of GVHD. Depletion of donor cells from B-cells resulted in a low incidence of GVHD in mouse model (Schultz et al. BMT1995:16:289–289). More recently, we observed a lower incidence of chronic (and to a lesser extent acute GVHD) in patients with CLL who received an allogeneic stem cell transplantation after a non-myeloablative conditioning regimen containing rituximab (Exp Hematol32:28–35, 2004). The purpose of this study is to investigate the effect of rituximab on GVHD in the setting of a more intense chemotherapy with BEAM, in patients who received an allogeneic peripheral blood stem cell from HLA-identical siblings. To test this hypothesis, we retrospectively studied 11 consecutive patients with non-Hodgkin’s lymphoma who received BEAM/Rituximab at the M. D. Anderson Cancer Center. We attempted to match these patients by age, donor-recipient gender, and donor-recipient CMV reactivity to a historical control of 44 patients with lymphoma, who received BEAM alone as a conditioning regimen, without the Rituximab. Tacrolimus and methotrexate were used for GVHD prophylaxis in both groups. A total of 10 patients in the study group, could be matched with 19 patients in the control group and were included in the final analysis. The outcome of the 2 groups is shown below: Rituximab-Study Group Control Group -value P No. of patients 10 19 Median age 41 44 0.4     (range) (19–55) (19–60) Patient-Donor sex-matched 9(82%) 18(95%) 0.6 Median # CD34 + cells infused (106/kg) 5.1 4.73 0.1 Patient or Donor CMV+ 9(82%) 18(95%) 0.6 Patient and Donor CMV − 1(10%) 1(5%) Median # prior chemoregimens 3 3 0.9     range (1–8) (1–9) Median follow-up 17 38     range (8–48) (27–77) Acute GVHD 2–4 (n,%) 5(50%) 7(37%) 0.5 Acute GVHD 3–4 (n,%) 3(30%) 5(26%) 0.6 Chronic GVHD (n, % cumulative incidence) 8 (90% + 15) 10 (53% + 12 0.01 Our data suggest that the described protective effect of Rituximab against GVHD in mouse models or in the setting of non-myeloablative allogeneic transplantation, may be overcome by the BEAM. This more intense conditioning regimen may induce more GVHD by enhancing T-cell cytokines release and by causing more gastrointestinal toxicity, thus allowing for a greater antigen presentation.

Abstract Abstract 4322 Background Single nucleotide polymorphisms (SNPs) in the innate immunity receptor NOD2/CARD15 have been demonstrated to modulate the outcome of allogeneic haematopoietic stem cell transplantation. The effect of the NOD2/CARD15 polymorphism seems to be associated with donor source as well as type of conditioning regimen. Methods We reviewed NOD2/CARD15 mutations in all donor/recipient pairs of 192 consecutive patients who received non-myeloablative allogeneic stem cell transplantation(SCT) at our institution between 2002 and 2006. All patients were treated uniformly with fludarabine 30 mg/m2/day for 3 days followed by 200 cGy TBI (n=154) or TBI alone (n=38) and received grafts from HLA-matched related (n=132) or unrelated (n=60) donors. Results Mutated alleles were observed in 36 of 192 (19%) patients and in 35 of 192 (18%) donors. These SNPs, however, did not have a significant impact on clinical outcome data (P > 0.05, Kaplan Meier and Fine & Gray's test). Acute graft-versus-host disease (GVHD) occurred in 24 of 61 (39%) patients with the polymorphism and in 66 of 131 (50%) patients without the polymorphism. Chronic GVHD developed in 28 of 55 (51%) patients with SNP pairs and in 79 of 121 (65%) patients with the wild type. The incidence of transplant-related mortality was 21% in both groups, 13 of 61 patients in the group with the polymorphism and 27 of 131 without the polymorphism. Relapse was seen in 23 of 61 (38%) patients with the SNP pairs and in 48 of 131 (37%) wild type patients. Finally, overall survival was 43% (26/61) in patients with the polymorphism and 39% (51/131) in patients without the polymorphism. Conclusion These data indicate that mutations in the NOD2/CARD15 genes do not influence the clinical outcome of non-myeloablative allogeneic SCT directly. Since NOD2/CARD15 variants are not recognized as a single significant prognostic factor, screening for NOD2/CARD15 when selecting a donor does not seem to have additional value in patients undergoing non-myeloablative SCT.

Abstract Introduction Adrenoleukodystrophy (ALD) is an autosomal recessive disorder with progressive neurodegeneration caused by the mutation of ABCD1 gene and allogeneic stem cell transplantation (SCT) at its early stage is recognized as the only effective treatment modality to control the neurological symptoms. But the transplant outcome according to the conditioning regimen is not well understood so far. Here we analyzed the transplant outcome of patients with ALD using the clinical data accumulated in the Japan Society of Hematopoietic Cell Transplantation and tried to find the favorable conditioning regimen. Methods From 1988 to 2010, 76 patients with ALD were transplanted and their age at transplant was 1-34 years old (median 8). Stem cell sources the patients received were bone marrow (sibling 26, non-sibling related donor 5, unrelated volunteer donor 17), and cord blood (sibling 1, unrelated 28). Conditioning regimen was classified into four categories of A: busulfan + cyclophosphamide +/- others, (n=25), B: melphalan + total lymphoid irradiation (TLI) / thoraco-abdominal irradiation (TAI) +/- fludarabine +/- anti-thymocyte globulin (n=23), C: fludarabine + melphalan +low dose total body irradiation (TBI) (n=18), and D: others (n=10). Results Sustained engraftment was obtained in 59 patients (77.8%) and it was significantly higher in bone marrow transplant (BMT) patients than cord blood transplant (CBT) patients (87.8% vs 60.7%, P=0.001). The incidence of acute graft-versus-host disease (GVHD), chronic GVHD and treatment related mortality of all patients were 7.9%, 19.3%, and 11.9%, respectively. Ten year overall survival (OS) and event free survival (EFS) of all patients were 83.7% and 64.1%, respectively. Ten patients died of either disease progression (n=2), or transplant related complications (n=8). Five year OS and EFS according to the conditioning regimen was A: 91.6% and 75.8%, B: 85.7% and 60.9%, C: 100% and 83.3%, D: 77.8% and 48.0%, respectively and they were not significant (P=0.379 in OS and P=0.183 in EFS, respectively). TBI was given to 22 patients with median dose of 4Gy (range 2-10.2) and sustained engraftment was obtained in 19 patients and all of 22 patients are alive. In patients who were not given TBI (n=54), 41 patients obtained engraftment and 44 patients are alive. OS according to presence or absence of TBI was 100% with TBI (n=22) and 86.1% without TBI (n=54) (P=0.091). By multivariate analysis for EFS, BMT and TBI were identified as good prognostic factors compared to CBT or non-TBI (HR 3.303, P=0.005, and HR 3.257, P=0.038, respectively), but OS of CBT was improved after 2005 compared to before 2004 (94.7% vs 68.6%, P=0.090). Conclusion Our results showed that conditioning regimen which includes TBI, even at low dose could provide better transplant outcome and the result of CBT improved after 2005 even though it was proved to be a significantly poor risk factor in the analysis of entire cohort. CBT enables urgent SCT when family donor is not available, and immediate transplant is essential for patients with ALD because of its nature. More precise assessment with brain MRI and neuropsychological examination is mandatory to evaluate the transplant outcomes of patients with ALD.

PURPOSE: Conventional allogeneic stem-cell transplantation (SCT) after a prior failed autograft is associated with a transplant-related mortality rate of 50% to 80%. The aim of the current study was to evaluate the safety and efficacy of sibling, HLA-matched, nonmyeloablative allogeneic SCT with donor lymphocyte infusion (DLI) in patients with lymphoid malignancy after failure of autologous SCT. PATIENTS AND METHODS: A total of 38 patients with refractory, progressive, or relapsed disease after autologous SCT were entered onto this study. The conditioning regimen consisted of the humanized monoclonal antibody CAMPATH-1H, fludarabine, and melphalan. Fifteen of 35 assessable patients received DLI after SCT. RESULTS: Sustained neutrophil engraftment was achieved in 37 recipients, and platelet engraftment was achieved in 35 patients. The estimated transplant-related mortality was 7.9% at day 100 and 20% at 14 months, the median duration of follow-up. Eight patients experienced grade I/II acute graft-versus-host disease (GVHD) after transplantation, but no grade III/IV GVHD was observed in this setting. However, grade III/IV GVHD occurred in seven patients who received DLI. The actuarial overall survival at 14 months was 53%, with a progression-free survival of 50%. DLI produced a further response in three of 15 recipients. CONCLUSION: Nonmyeloablative allogeneic SCT after CAMPATH-1H–containing conditioning is a relatively safe option compared with conventional allogeneic transplantation for patients who have failed previous autologous SCT. The low incidence of early GVHD enabled the subsequent administration of DLI to improve further clinical responses in this poor-risk group of lymphoma and myeloma patients.
