Abstract Abstract 2308 Poster Board II-285 Introduction: Dose-reduced conditioning followed by allogeneic stem cell transplantation has become a treatment option for patients with multiple myeloma. However, the experience using unrelated donor is limited. Patients and Methods: From 2002 to 2007, 49 myeloma patients with relapse to a prior autologous SCT were included in a prospective multicenter trial to determine the efficacy of a reduced melphalan (140 mg/m2)/fludarabine regimen followed by allogeneic SCT from unrelated donors. GvHD prophylaxis consisted of anti-lymphocyte globulin (ATG-Fresenius®), cyclopsorin A and short course of MTX. Results: No primary or secondary graft failure was observed and all patients showed leukocyte and platelet engraftment after a median of 15 and 19 days, respectively. Acute graft-versus-host disease (GvHD) grade II to IV occurred in 25% and chronic GvHD in 35% of the patients. Limited GvHD was seen in 29 % and extensive GvHD was seen in 6 % of the patients. Overall response rate at day 100 was 95% including 46% complete remission (CR). Cumulative incidence (CI) of non-relapse mortality at one year was 25% (95% CI: 13-37%) and significantly lower for HLA matched compared to mismatched SCT (10% vs. 53%, p=0.001). During follow-up 22 patients experienced relapse (54 %) resulting in a cumulative incidence of relapse at 1, and 3 years of 27% (95% CI: 14-40%) and 55% (95% CI: 40-70%), respectively. The median time to relapse was 318 days (r: 56 – 861). After a median follow up of 43 months, the estimated 5-year progression-free (PFS) and overall survival (OS) rates were 20% and 26%, respectively and were significantly better for matched in CR at day 100 (41 vs. 7%, p=0.04 and 56 vs. 16%, p=0.02). Conclusions: Allogeneic stem cell transplantation from unrelated donors after a reduced intensity regimen is feasible, but an optimal donor selection is mandatory for a low non-relapse mortality. The high relapse incidence remains a major concern should be improved by including posttransplant strategies to upgrade remission status. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 1201 Poster Board I-223 Introduction: Autologous stem cell transplantation followed by a dose-reduced conditioning and allogeneic stem cell transplantation from HLA-identical siblings has become a treatment option for patients with multiple myeloma. However, only a minority of the patients with multiple myeloma has an HLA-identical sibling and the experience using unrelated donor in this setting is limited. Patients and Methods: From 1997 to 2007, 73 patients (male:45; female:28) with multiple myeloma stage II/III and a median age of 49 years (r, 29-64) were included in a prospective trial to determine the efficacy of a tandem auto-allogeneic stem cell transplantation SCT) from HLA-identical sibling (n=24) or unrelated donors (n=45). Unrelated donor were either fully HLA matched (n=29) or had one mismatch (n=16).Deletion 13q14 could be analyses in 64 pts was found to be positive in 66% of the pts. Del13q14 was more present in patient with unrelated (n=42) than with related (n=22) donors. Stem cell source was PBSC (n=69) or bone marrow (n=4). Induction-chemotherapy consisted of a median of 4 cycles anthracycline-based therapy in 60 pts, or of thalidomide- (n=3) or bortezomib- (n=8) based regimen. 6 pts did not respond to induction therapy and received salvage chemotherapy before autologous SCT. Conditioning prior auto SCT consisted of melphalan 200mg/m2. After a median of 110 days (range 39-228) patients received a reduced intensity regimen with melphalan (140 mg/m2)/fludarabine regimen followed by allogeneic SCT from related (n=24) or unrelated (n=45) donors. GvHD prophylaxis consisted of anti-lymphocyte globulin (ATG-Fresenius®), cyclopsorin A and short course of MTX. Results: No primary or secondary graft failure was observed and leukocyte engraftment was achieved after a median of 15 days (range, 9-27), respectively. Acute graft-versus-host disease (GvHD) grade II to IV occurred in 38% and chronic GvHD in 22% of the patients. Limited GvHD was seen in 16 % and extensive GvHD was seen in 6 % of the patients. There was no difference regarding incidence of GvHD between HLA-identical sibling and unrelated donors. Overall response rate at day 100 was 94% including 55% complete remission (CR) and did not differ between related and unrelated SCT. Cumulative incidence (CI) of non-relapse mortality at one year was 20% (95% CI:11-29%) and did not differ between MUD and MRD (21 vs 17%, p 0.35). The cumulative incidence of relapse at 3 and 5 years was 30% (95% CI:19-41%) and 42% (95% CI: 29-55%), respectively with no difference between related and unrelated SCT at 5 years: 36 vs 44%(p= 0.6). The only significant factor for higher relapse incidence at 5 years was the presence of del13q14 (60 vs 20%, p= 0.007). After a median follow up of 40 months (r., 26-100), the estimated 5-year progression-free (PFS) and overall survival (OS) rates were 31% (95%CI: 19-43%) and 54% (95% CI: 42-64%), respectively, with no difference between related and unrelated SCT. Due to the higher relapse incidence only presence of del13q resulted in a significant worse 5- year OS and DFS (45 vs 77%, p=0.02 and 18 vs 57%, p=0.04). Conclusions: Unrelated donors as stem cell source for auto-allogeneic tandem stem cell transplantation for newly diagnosed myeloma patients resulted in similar NRM, relapse-incidence, DFS and OS than HLA-identical sibling transplantation and can therefore be used as alternative stem cell source. Outcome after transplantation is better for patients lacking del 13q14. Disclosures: No relevant conflicts of interest to declare.

Abstract Graft-versus-host disease (GVHD) is a significant complication of allogeneic stem cell transplantation (alloSCT). The proteasome inhibitor bortezomib has immunomodulatory properties of potential benefit for GVHD control. We undertook a phase 1 trial of bortezomib, tacrolimus, and methotrexate for GVHD prophylaxis after reduced-intensity conditioning alloSCT using human leukocyte antigen–mismatched unrelated donors. Twenty-three patients were enrolled. Bortezomib dose levels of 1, 1.3, and 1.5 mg/m2 were evaluated with 5, 3, and 5 patients, respectively. Ten additional patients were accrued at the 1.3 mg/m2 bortezomib dose level. Bortezomib-related toxicity was minimal. With a 12-month median follow-up, grade II-IV acute GVHD occurred in 3 patients, a 180-day cumulative incidence of 13%. Chronic GVHD occurred in 9 patients, a 1-year cumulative incidence of 41%. At 1-year, the nonrelapse mortality was zero, cumulative incidence of relapse/progression was 29%, and overall, progression-free, and event-free survival were 75%, 64%, and 59%, respectively. Bortezomib is a promising novel immunomodulatory agent in allogeneic transplantation. This study was registered at http://www.clinicaltrials.gov as #NCT00369226.

Abstract The role of allogeneic stem cell transplantation (SCT) in the treatment of multiple myeloma (MM) is unclear. High transplant-related mortality has been regarded as a particular problem. At the Helsinki University Central Hospital 86 patients with MM have been treated with allogeneic SCT since 1995. The conditioning was at first myeloablative (MA). Since 1999 reduced intensity conditioning (RIC) after autologous SCT has been used in most cases, but a number of young patients with aggressive disease have been transplanted with MA conditioning. Of the patients 42 were male and 44 female. The median age at SCT was 50 (27–64) years. The median number of chemotherapy lines before allogeneic SCT was 1 (range 1–7). Prior autologous SCT had been performed to 55 patients. The median time from diagnosis to allogeneic SCT was 12 (4–168) months, and the time between autologous and allogeneic SCT 6 (2–146) months. At the time of allogeneic SCT 9 patients were in CR, 63 in PR, 4 had stable disease, and 10 progressive disease. 72 patients had a sibling donor: 68 were HLA-identical, one 1 antigen mismatch, 3 identical twins. 14 patients had an HLA-matched unrelated donor. The conditioning was MA in 32 and RIC in 54 patients. The MA conditioning consisted of Cy/TBI in 22, Mel/TBI in 3, and Treosulfan/Fld in 7 patients. RIC was the Seattle protocol (Fld/TBI 2 Gy) in 45, reduced Treosulfan/Fld in 8, and Fld/Cy in 1 patient. 26 patients received a BM graft and 60 patients a PB graft. As GVHD prophylaxis, 18 patients were given CsA/Mtx, 20 CsA/Mtx/MP, 45 CsA/MMF, and 3 nothing (identical twins). The median follow-up time from allogeneic SCT was 39 (2–136) months, 46 (7–136) months for the MA patients and 34 (2–92) months for the RIC patients, respectively. The OS was 50% at 61 months post SCT and there have been no deaths after this time-point. The median PFS was 31 months. After this time-point the disease has progressed in one case, at 90 months. Of the 32 MA patients 16 (50%) and of the 54 RIC patients 22 (41%) have achieved CR after SCT. The cumulative incidence of acute GVHD grade II-IV was 28%. The cumulative incidence of chronic GVHD was 72%, 58% in the MA and 83% in the RIC patients (p=0.074). The incidence of extensive chronic GVHD was significantly (p=0.012) higher in RIC than MA patients, 66% vs. 23%. There were no statistical differences in the incidence of acute or chronic GVHD by donor type (72 siblings/14 unrelated). The cumulative 100-day transplant related mortality was 4.5% and that of the whole follow-up time 14%. 26 patients have died. The cause of death was myeloma in 15, GVHD in 7, and infection in 4 patients. In conclusion, in the present material transplant-related mortality was low and the survival encouraging, supporting the use of allogeneic transplantation with curative aim in selected cases. Developing chemotherapy, given prior to transplantation, may improve the results.

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 We compared anti-thymocyte globulin (ATG-Fresenius median dose 60 mg/kg: n= 48) with alemtuzumab (Campath-1H 100mg: n=25) in 73 patients with multiple myeloma, who underwent dose-reduced conditioning with melphalan and fludarabine, followed by allogeneic stem cell transplantation from matched (n=63) or mismatched (n=10) unrelated donors. Patients of the ATG group had higher age (median 50 vs 47 years, p=0.05), more prior high-dose chemotherapies (p<0.001), while in the Campath group more bone marrow as stem cell source was used (p<0.001). No primary graft failure occurred in both groups. Patients receiving alemtuzumab had a significant faster engraftment of leukocyte (p=0.03) and of platelets (p=0.02) and a lower incidence of acute GvHD grade II-IV (24 vs 47%, p=0.05). However, after treatment with donor lymphocyte infusion due to persistent disease or mixed hematopoietic chimerism the difference of acute GvHD grade II-IV between alemtuzumab and ATG treated patients did not reach statistical significance (32 vs 47%, p=0.2). No difference in incidence of chronic GvHD was observed (25 vs 33%, p=0.6) More CMV seropositive patients in the alemtuzumab group experienced CMV reactivation (100% vs 47%, p=0.001). The cumulative incidence of treatment related mortality at 2 years for ATG and Campath was 29.3% (CI=17–50%) vs 28.5% (CI=15–54%), p=0.7. No significant difference could be observed in the estimated 2 years OS and PFS between ATG and Campath: 53% (CI:38–75) vs 45% (CI:28–73) and 29% (CI:16–54) and 36% (CI: 20–62), respectively. For PFS, in a multivariate analysis relapse to prior high-dose chemotherapy was the strongest negative factor: HR 2.9, p= 0.001. Including only those patients who did not experienced any relapse at time of allogeneic stem cell transplantation the Campath-group had a 2.5 fold higher risk of progression in comparison to the ATG group, but without reaching statistical significance (HR: 2.5, p=0.15). Ten out of 73 patients had KIR-ligand mismatch in GvH direction. While in patients without KIR-ligand mismatch the cumulative incidence of relapse at two years was 50%, none of the KIR-ligand mismatched patients relapsed so far (p=0.02). The immunosuppressive effect from Campath is stronger than ATG resulting in less acute GvHD, but requires more DLI procedures to control diseases and resulted in a trend to a lower PFS in chemosensitive patients. This preliminary data further implicated a major role of KIR-ligand mismatch transplantation in multiple myeloma

Abstract Background/Patients and Methods: NST is increasingly being used as a means of establishing a graft-versus-malignancy (GVM) effect with less regimen related toxicity. Between 9/01 and 7/04, 39 patients (pts) with high risk/relapsed/refractory HM who were not candidates for full intensity allogeneic stem cell transplantation underwent NST using Pentostatin/TBI. The median age of pts was 52 years (range 22–70). The median number of prior therapies was 4 (range 0–8) including prior autologous stem cell transplantation in 22 pts. Diseases transplanted included chronic lymphocytic leukemia/indolent non-Hodgkin’s lymphoma (NHL, n=6), aggressive NHL (n=8), mantle cell lymphoma (n=3), Hodgkin’s disease (n=6), myeloproliferative disorders (n=4), myelodysplastic syndromes (n=4), and acute myelogenous leukemia (AML, n=8). Conditioning consisted of Pentostatin 4 mg/m2 daily on day −21, −20, and −19, followed by 200 cGy TBI on day −1. Post-grafting immunosuppression consisted of cyclosporine/mycophenolate mofetil. Results: Stem cell transplantation was from matched related (n=14) or unrelated (n=25) donors. Death prior to 100 days post transplant occurred in 7 patients. Grade III/IV toxicities included hematologic (n=10 pts), infectious (n=5) and other non-infectious (n=4). The median nadir values (day −21 to day 0) for hemoglobin, neutrophil count and platelet count were 10.7 g/dl (range 7.8–12), 1056/mm3 (range 0–5336), and 174/mm3 (range 24–523) respectively. Three pts failed to engraft; two patients with myelofibrosis (both of whom had autologous reconstitution) and one patient with high risk AML (who died of complications of fungal sepsis without hematologic recovery). The median chimerism values for CD3+ cells and WBC at day 28 are 80% and 95% donor cells respectively. The median chimerism values for CD3+ and WBC at day 70 are 95% and 95% respectively. There have been no late graft failures. The cumulative incidence of all grades of acute graft-versus-host disease at day 100 was 40% and was more common in unrelated donor transplants (60% vs. 15%, P=0.012). Chronic graft-versus-host disease has developed in 69% of patients. The cumulative incidence of relapse for all patients is 30%, and is lower for unrelated donor transplants than matched related donor transplants (46% vs. 20%, P=0.02). The probability of event-free and overall survival at two years is 52% and 56% respectively. Conclusions: This regimen is associated with acceptable toxicity. Engraftment has not been an issue with the exception of two pts with myelofibrosis. Pts receiving unrelated donor grafts have a higher incidence of graft-versus-host disease and a lower relapse rate. This represents indirect support for the presence of a GVM effect. A prospective study using a modified Pentostatin schedule (starting at day − 10) is ongoing based on the nadir of host T-cells identified in this study.

Abstract BACKGROUND: Allogeneic stem cell transplantation (allo-SCT) with reduced-intensity conditioning (RIC) is gaining increasing acceptance in relapsed/refractory (R/R) Hodgkin’s lymphoma (HL), but there are little or no outcome data with matched unrelated donors (MUDs). METHODS: Fifty-eight patients with relapsed or refractory Hodgkin’s lymphoma (HL) underwent allogeneic stem cell transplantation (allo-SCT) following a reduced-intensity conditioning (RIC) regimen from a matched related donor (MRD; n=25) or a matched unrelated donor (MUD; n=33). The median age was 32 years (range 19–59). The median number of chemotherapy regimens received prior to allo-SCT was five (range 2–9). Forty-eight (83%) patients had received a prior autologous (auto) SCT. The median time to progression after auto-SCT was five months (1–34). Disease status at SCT was sensitive relapse (n=30) or refractory relapse (n=28). The conditioning regimen employed was fludarabine (125–130 mg/m sq over 4–5 days), melphalan (140 mg/m sq IV over 2 days) (FM) and antithymocyte globulin (thymoglobulin 6 mg/kg over 3 days) was added for the most recent fourteen MUD transplants. Graft-vs-host disease (GVHD) prophylaxis included tacrolimus and mini-methotrexate. RESULTS: Chimerism studies indicated 100% donor-derived engraftment in all patients (100%). Cumulative 100-day and 2-year transplant-related mortality (TRM) were 7% and 15%, respectively, (100-day TRM MRD vs. MUD 6% vs. 8%, p=ns; 2-year MRD vs. MUD 13% vs. 16%, p=ns). The cumulative incidence of acute (grade II–IV) GVHD (first 100 days) was 28% (MRD vs. MUD 12% vs. 39%, p=0.04). The cumulative incidence of chronic GVHD at any time was 74% (MRD vs. MUD 57% vs. 89%, p=0.003). Fourteen pts (24%) received a total of 25 (range 1–5) donor leukocyte infusions (DLIs) for disease progression/relapse (PD). Five of them (35%) received salvage chemotherapy as well, and nine (64%) developed acute GVHD after the DLI. Thirty-six patients (62%) are alive (23 in remission) with a median follow-up of 24 months (4–78). The f/up is 23 months (4–53) for alive pts always in remission. Twenty-two patients (38%) expired, and relapse-related mortality was 24%. Projected 2-year overall (OS) and progression-free (PFS) survival are 64% (49–76) and 32% (20–45), with projected 2-year PD at 55% (43–70). There was no statistically significant difference between MRD and MUD transplants with regard to OS (p=0.1), PFS (p=0.9) and PD (p=0.8). There was a clear trend for the response status prior to allo-SCT (complete response, complete response undefined vs. all others) to favorably impact PFS (p=0.07) and PD (p=0.049), but not OS (p=0.4). Partial responders and patients with stable or refractory disease fared similarly with regard to OS and PFS. CONCLUSIONS: Despite the expected higher incidence of acute and chronic GVHD, MUD RIC allo-SCTs had TRM, PFS, and OS comparable to MRD allo-SCTs. Day 100, 2-year TRM and OS/PFS data appear very encouraging in these very high-risk, extensively pretreated patients. Response status at transplant seems to affect outcome, and PD remains a major obstacle. The use of unrelated donors would greatly expand donor availability for these patients.

Abstract Variation in baseline host immune status contributes to inconsistent donor engraftment and may impede maximal graft-versus-myeloma effects after reduced-intensity allogeneic stem cell transplantation (RI-alloSCT) for advanced multiple myeloma. We performed a phase II study to determine the efficacy of a novel salvage regimen, EPOCH-F, which was designed to provide immune depletion and disease control prior to RI-alloSCT, in 22 patients with advanced multiple myeloma. EPOCH is an infusional chemotherapeutic regimen consisting of etoposide, vincristine and adriamycin, with prednisone, cyclophosphamide and fludarabine and given in 21 day cycles prior to RI-alloSCT. Patients received at least 1 and no more than 5 cycles of EPOCH-F gudied by peripheral blood CD4+ T cell count. Pts achieving adequate lymphodepletion proceeded to RI-alloSCT; otherwise patients proceeded to RI-alloSCT after 5 cycles or if there was disease progression during EPOCH-F, regardless of CD4 count. Median age was 53 years (range, 36–65); median time from initial therapy to transplant was 12 months (range, 2–168). Median number of prior therapies was 2 (range, 1–8), while 63% had chemotherapy sensitive disease. 68% of patients had received a novel agent. Patients received a median of 3 cycles (range, 1–5) of EPOCH-F. Therapy was well tolerated with manageable toxicities, mostly hematologic. Neutropenia (grade IV) was the most common toxicity seen in 77% of the administered cycles with only 6 episodes of neutropenic fever. Median lymphocyte count decreased from 1423/μL (range, 335–2788) to 519/μL (range, 102–1420); CD4 count decreased from 320/μL (range, 130–1366) to 115/μL (range, 30–309). In 21 evaluable patients, the overall response rate to EPOCH-F was 22% and 68% had stable disease. 13% of patients achieved CR/nCR. Only 1 patient progressed while on therapy. 20 patients received allograft from HLA matched sibling donors and were evaluable for engraftment. Median Day 100 chimerism was 100% (range 60–100, mean 95). 70% of patients achieved ≥VGPR including CR/nCR, while CR/nCR was seen in 40% of the patients. Median overall survival was 46.1 months. 10 (50%) patients are currently alive. Acute GVHD (grade II–IV) was seen in 47% and chronic GVHD (grade III–IV) was seen in 52% of patients. Treatment-related mortality at 100 days was 5% and 30% at 60 months. EPOCH-F is an active regimen which facilitates consistent and rapid full donor engraftment following RI-alloHSCT from related donors in patients with advanced multiple myeloma.

Abstract Abstract 1019 Allogeneic stem cell transplantation is the only curative treatment for myelofibrosis. Here we present a long–term follow up of patients with myelofibrosis treated with reduced-intensity allogeneic stem cell transplantation in the prospective multicenter study conducted by the MDS subcommittee of the Chronic Leukemia Working Party of the European Group for Blood and Marrow Transplantation (EBMT) (study registration NCT 00599547). From 2002 to 2007, a total of 103 patients with primary (63 pts) or post-polycythemia vera and –essential thrombocythemia myelofibrosis (40 pts) from seventeen transplantation centers in three nations were included in the study. There were 62 males and 41 females with a median age of 55 years (range, 32–68 years). Risk profile according to Lille score was low risk with constitutional symptoms (17%), intermediate risk (53%) and high risk (30%). All but three of the patients received peripheral stem cells as stem cell source from either related (n=33) or unrelated donor (n=70) and a conditioning with Busulfan (10mg/kg orally or 8mg/kg intravenously),Fludarabin (180 mg/m2) and antithymocyte-globulin (ATG-Fresenius®) according a previously published protocol. According to high-resolution HLA typing, 21 patients had at least one allele or antigen HLA mismatch. From 88 patients with a known JAK2V617F-status 63 harbored the mutation. After a median follow up of 60 months (range 9–109 months), 41 patients had chronic graft vs. host disease which was extensive in the half of cases. The 5-year and 8-year estimated overall survival (OS) was 68% and 65%, respectively with a stable plateau after 5,3 years follow up (Figure-1). Estimated 5-year disease-free survival was 40%. The cumulative incidence of relapse/progression at 3 and 5 years was 22% and 28% and the non-relapse mortality at 1 and at 3 years was 18% ands 21%, respectively.Figure-1Figure-1. Within the overall follow up period, relapse/progression occurred in 28 patients. Twenty one of them were treated with donor-lymphocyte infusions (DLI) and/or a second allogeneic transplantation (n=11). Sixteen of those were at the last follow up alive. The estimated OS of all relapsed patients after a median follow up of 46 months (range 4–62 months) beginning from the time of relapse was 55%. In multivariate analysis advanced age >55years (HR: 4.69, p=0.001), absence of JAK2V617F mutation (HR: 2.50, p=0.02), mismatched donor (HR: 3.62, p=0.002) were significant independent predictors for reduced OS. This update of a prospective trial using reduced intensity conditioning followed by allogeneic stem cell transplantation for myelofibrosis confirmed a very good long-term OS. Relapse still occurs in about 30% and remains the main problem after transplantation. However, with adoptive immunotherapy using DLI or even second allogeneic transplantation a second remission with long term survival can be induced in about 50% of the relapsed patients. Developing methods for remission monitoring and early prediction and treatment of relapse should be the focus of future studies.
