Abstract Abstract 4357 Background This retrospective study evaluates outcomes of patients (pts) treated with autologous stem cell transplantation (ASCT) and subsequent therapy for relapsed/refractory Hodgkin lymphoma (HL) who underwent ASCT in 7 transplant centres in Czech Republic. Patients and methods 194 pts with relapsed/refractory HL treated with ASCT (184 single, 10 tandem) between 01/2000 and 06/2009 were analyzed. Overall survival (OS) and progression-free survival (PFS) since the time of ASCT were evaluated according to Kaplan-Meier methods. Outcome of pts relapsing after ASCT was evaluated since the time of relapse. Different salvage modalities after ASCT and their impact on survival were compared with log-rank test. Results Median age of pts at time of ASCT was 33 (range 18-66) years. Best response observed after ASCT: complete remission (CR) in 124 pts (64%), partial remission (PR) in 35 pts (18%), stable disease (SD) in 2 pts (1%) and relapse/ progression in 33 pts (17%). Median follow-up was 44 months (m)(range, 3-108). Projected 5-year OS was 71% (median not reached) and PFS 54% (median 86m). Overall 70 pts progressed/relapsed after ASCT and allogeneic stem cell transplantation (alloSCT) was planned in 38 of them, but carried out only in 25 pts (3 myeloablative and 22 reduced intensity regimens). 37 pts were scheduled for other salvage therapy, 4 pts underwent second ASCT and 4 pts did not receive further treatment. Median survival of 70 pts since relapse after ASCT was 16.9 months. Median survival since relapse after ASCT in pts with or without alloSCT was 31.8 and 12.4 months respectively, but the difference was not statistically significant. Overall 51/194 (26.3%) pts died. 11 of 124 pts died in continuous remission after ASCT due to non-relapse mortality including transplant related mortality in 8pts (6.4%). 40/70 relapsed/refractory pts died: 29 in relapse/progression (20 after salvage treatment, 9 after alloSCT) and 11 pts due to non-relapse mortality (5 after salvage treatment and 6 after alloSCT). Conclusion Efficacy of ASCT was confirmed in 113/194 surviving pts (58%) in continuous remission. Median survival of relapsed pts following ASCT was 16.9 m. AlloSCT seems to improve survival in relapsed/refractory patients, although the difference is not statistically significant. New drugs should be offered to patients failing transplantation treatment.

Abstract Introduction: The role of autologous hematopoietic stem cell transplantation (auto-HCT) in the management of patients with Waldenström Macroglobulinemia (WM), a rare, indolent lymphoma, has not been established. We had previously published our experience with auto-HCT in a small cohort of WM patients1. Here, we present an updated analysis of auto-HCT with a larger cohort of WM patients. Methods and study population: The study cohort was comprised of 29 patients who underwent high-dose chemotherapy and auto-HCT at MD Anderson Cancer Center (MDACC). The Kaplan-Meier method was used to create survival curves. Overall survival (OS) was defined as the duration from date of transplant to death or last date of follow-up in living patients. Progression-free survival (PFS) was defined as the duration from date of transplant to either progressive disease or death, whichever occurred first. Results: Median age at auto-HCT was 60 (range, 43-75 years). Eight patients (28%) had concurrent light chain amyloidosis (AL). Of the five patients who had MYD88 testing completed, 3 were positive for the MYD88 mutation. Additionally, of these 3 patients, 2 were also positive for CXCR4 mutation. Patients received a median of 2 lines (range 1-6) of therapy prior to auto-HCT; 3(10%) patients had primary refractory disease, 8(28%) were in first remission, and 18 (62%) had relapsed disease. Median time from transplant to last follow-up for the surviving patients was 5.3 years. Preparative regimens received by the patients were: Melphalan (n=20), BEAM-R (n=2), Busulfan/Melphalan (n=1), Cyclophosphomaide/Etoposide/total body irradiation (n=1), Thiotepa/Busulfan/Cyclophosphamide (n=1), and Carmustine/Thiotepa (n=1). Three patients further went on to receive allogeneic transplant either after relapse from auto-HCT or due to disease transformation to aggressive lymphoma. Twenty-eight patients achieved engraftment with a median time to neutrophil engraftment of 11 days (range, 10-15 days). One patient suffered primary graft failure due to progression of disease and died 84 days after transplant. Non-relapse mortality was 3.4% at 1 year. All patients were eligible for response evaluation. The median OS from diagnosis was 12.2 years. Overall response rate was 96%: complete response (n=8, 27.6%), very good partial response (n=5, 17.3%), partial response (n=15, 51.7%), and progressive disease (n=1, 3.4%). PFS and OS at 5 years were 43.3% and 62.9%, respectively. Median PFS and OS from auto-HCT were 4.1 and 7.3 years (Fig. 1A). The median OS from auto-HCT in first remission + primary refractory and relapsed disease was 8.2 years and 4.1 years, respectively.16 patients were alive at the time of censoring while 13 patients had died. Causes of death include relapsed disease (n=6), secondary malignancy (n=2), infection (n=1), chronic graft-versus-host disease (n=1), and unknown (n=3). 8 patients (28%) were positive for concurrent AL amyloidosis. The sites of amyloid involvement were kidneys (n=2), lungs (n=1), bone marrow (n=1), heart(n=1), lymph nodes(n=1), gastrointestinal tract (n=1) and subcutaneous fat aspirate(n=5). The median overall survival for patients with amyloid involvement (n=8) was 12 years. On univariate analyses, the number of chemotherapy regimens prior to transplant (≤ 2 vs >2 lines) was the strongest predictor of overall survival (p=0.03, HR 0.3, CI: 0.09-0.9, log-rank) and PFS (p=0.001, HR 0.24, CI: 0.07-0.85, log-rank). The median PFS in patients with ≤ 2 lines and > 2 lines of therapy was 71 months versus 19 months, respectively (Fig. 1B). Conclusion: Auto-HCT is safe and feasible in selected patients with WM, with a high response rate and durable remission even in patients with relapsed or refractory disease.

Abstract Abstract 3077 Blastic plasmacytoid dendritic cell neoplasm (BPDC), formerly known as blastic NK cell lymphoma, is a rare hematopoietic malignancy preferentially involving the skin, bone marrow and lymph nodes. The overall prognosis of BPDC is dismal. Most patients show an initial response to acute leukemia-like chemotherapy, but relapses with subsequent drug resistance occur in virtually all patients resulting in a median overall survival of only 9–13 months. However, anecdotal long-term remissions have been reported in young patients who received early myeloablative allogeneic stem cell transplantation (alloSCT). We therefore performed a retrospective analysis of patients identified in the EBMT registry in order to evaluate the outcome of autologous stem cell transplantation (autoSCT) or alloSCT for BPDC. Eligible were all patients who had been registered with a diagnosis of BPDC or Blastic NK cell lymphoma and had received autologous stem cell transplantation (autoSCT) or alloSCT in 2000–2009. Centres were contacted to provide a written histopathology and immunophenotyping report and information about treatment and follow-up details. Patients who did not have a diagnostic score ≥ 2 as proposed by Garnache-Ottou et al. (BJH 2009) were excluded. RESULTS: Overall, 139 patients could be identified in the database who fulfilled the inclusion criteria (alloSCT 100, autoSCT 39). Of 74 patients for whom the requested additional information could be obtained, central review confirmed the diagnosis of BPDC in 39 patients (34 alloSCT, 5 autoSCT). The 34 patients who had undergone alloSCT had a median age of 41 years (range: 10–70 years), were transplanted from a related (n=11) or unrelated donor (n=23); received peripheral blood stem cells (n=9), bone marrow stem cells (n=19) or cord blood (n=6); and had been treated with a reduced intensity conditioning regimen (RIC, n=9) or myeloablative conditioning (MAC, n=25). Nineteen of 34 patients were transplanted in CR1. After a median follow up time of 28 months (range: 4–77+ months), 11 patients relapsed (median time to relapse: 8 months, range: 2–27 months) of whom 8 died due to disease progression. 9 patients died in the absence of relapse. No relapse occurred later than 27 months after transplant. Median disease free survival (DFS) was 15 months (range: 4–77+ months) and median overall survival (OS) was 22 months (range: 8–77+ months; Figure 1a). However, long-term remissions of up to 77 months after alloSCT could be observed. Patients allografted in CR1 tended to have a superior DFS (p=0.119) and OS (p=0.057; Figure 1b). MAC was associated with a better OS (p=0.001) which was attributable to the significantly higher non-relapse mortality (NRM) rate of patients after RIC (p=0.014), who had been significantly older (age RIC: 56 years, age MAC: 36 years, p=0.0014). The relapse rate was not different in patients after RIC and MAC, respectively. However, there was no survivor after RIC. Median age in the autoSCT group was 47 years (range: 14–62 years). Three of 5 patients were transplanted in CR1 of whom 1 patient relapsed after 8 months, 1 patient experienced treatment related mortality and 1 patient remained in CR for 28 months. The 2 remaining patients had more advanced disease at autoSCT and relapsed 4 and 8 months thereafter. CONCLUSION: AlloSCT is effective in BPDC and might provide curative potential in this otherwise incurable disease, especially when performed in CR1. However, it remains to be shown by prospective studies if the potential benefit of alloSCT in BPDC is largely due to conditioning intensity, or if there is a relevant contribution of graft-versus-leukemia activity.

Abstract Introduction: Ruxolitinib was the first JAK 1/2 inhibitor (JAKi) approved for myelofibrosis (MF), with several other JAKi in development. Ruxolitinib was approved on the basis of reducing splenomegaly and improving constitutional symptoms, but its effect on subsequent allogeneic stem cell transplantation (SCT) is not well understood. Retrospective studies to date have reported mixed outcomes after SCT for MF patients with previous exposure to JAKi. In this multicenter retrospective study, we report on outcomes of patients with MF treated with SCT at our institutions. Methods: We analyzed outcomes for 184 consecutive patients at three institutions who underwent SCT for primary or secondary MF. Primary outcomes included overall survival (OS), progression free survival (PFS), and graft-versus-host-disease (GVHD)-free and relapse-free survival (GRFS), all measured from the time of SCT. Cox proportional hazard regressions were fit to estimate the association between the use of JAK 1/2 inhibitors prior to SCT and OS, PFS, and GRFS, adjusting for donor type and DIPSS-plus status. p<0.05 was considered statistically significant. Results: 72 patients received a JAKi prior to SCT, while 112 did not. Patients in these two groups were well-matched with respect to age, sex, DIPSS plus score, conditioning, and donor type (Table 1). Median follow-up was 31.2 months (range: 0.8-146.3 months). In univariate analysis, there was no difference in OS (JAKi: 4-yr OS 56.7% [95% CI 40.9-69.8%] vs. no JAKi: 43.6% [95% CI 32.9-53.9%], p=0.49), PFS (JAKi: 4 yr PFS 54.1% [95% CI 40.8-65.7%] vs. no JAKi: 43.9% [95% CI 33.4-53.9%], p=0.77), or GRFS (JAKi: 8-month GRFS 56.6% [95% CI 44.1-67.4%] vs. no JAKi: 50.4% [95% CI 40.4-59.5%], p=0.62) in the overall population; there was similarly no difference when comparing only intermediate-risk or only high-risk patients. In multivariate analysis, there was no difference in these outcomes for patients based on previous JAKi exposure when accounting for DIPSS plus score and donor type (related vs unrelated). Rates of acute GVHD were similar between the two groups (JAKi: 53.5% vs. no JAKi: 55.0%, p=0.88), including grade 3 or 4 acute GVHD (JAKi: 16.9% vs no JAKi: 19.8%, p=0.70). Conclusions: Our data suggest that there is no statistically significant difference in OS, PFS, GRFS, or rates of acute GVHD after SCT for MF patients based on previous JAKi treatment. This was true overall and after adjusting for DIPSS plus risk score or donor type. Given the retrospective design of our study, we were not able to assess prior response to JAKi or splenomegaly at SCT, which may influence outcomes. Given mixed results in the literature to date, we eagerly await the results of ongoing phase 2 trials of JAKi prior to SCT for MF. Disclosures Ho: Jazz Pharmaceuticals: Consultancy.

Background: Survival in patients (pts) with relapsed/refractory (R/R) acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS) is dismal. Treatment options are limited; however, a proportion of these individuals can be rescued by allogeneic stem cell transplantation (allo-SCT). Historically, allo-SCT, especially for R/R myeloid diseases, has used myeloablative regimens and no T-cell depletion (TCD) to maximize graft-versus-leukemia effect, often restricting this approach to younger and fit pts with matched donors. The aim of this study was to investigate outcomes of in vivo T-cell depleted stem cell transplantation (TCD-SCT) in a high-risk AML and MDS population. Methods: We performed a retrospective analysis of 141 patients with R/R AML (n=108)/high risk MDS (RAEB or CMML, n=33) who received TCD-SCT at our center from 2002-2015. Median age was 55 years (18-71) with 37 (26%) pts older than 60. Patients underwent in vivo TCD with alemtuzumab or ATG and 117 (88%) received reduced-intensity conditioning (RIC). Alemtuzumab was generally given as 100 mg total divided over 5 days whereas rabbit ATG dosing included days -1, - 3, -5 (+/- on day -7). Alemtuzumab usually partnered with matched related (n=65; 46%) or unrelated (n=53; 38%) peripheral blood stem cell (PBSC) grafts whereas ATG mostly was a component of umbilical cord grafts combined with a CD34 selected haploidentical donor (haplo-cord) (n=23; 16%). Prognostic factors such as age, HCT-CI, CIBMTR score (Duval 2010), revised disease risk index (R-DRI), donor type and pre-transplant disease status were analyzed. Multivariate cox regression models were considered from forward selection for factors with a p value <0.1 in univariate analysis. Results: Table 1 summarizes baseline characteristics. Among the 141 R/R AML or high risk MDS pts, AML predominated (77%). Sixty six (47%) pts had primary induction failure (PIF), 42 (37%) had relapse and 33 (23%) had high risk MDS. Eighty three pts (59%) had peripheral blasts at time of TCD-SCT. Cumulative incidence (CI) of relapse for all pts was 53% and non-relapse mortality was 28% at 2 yrs. Two and 5 yr PFS rates for the group were 19% and 11%, respectively. Two and 5 yr OS rates for the group were 30% and 18%, respectively. Figure 1 shows OS by disease type. Day 100 mortality was 18%. Twenty one percent developed Grade 2-4 acute GVHD (aGVHD) (6% Grade 3-4), and only 5% developed chronic GVHD (cGVHD) requiring therapy. Figure 2 shows CI of cGVHD amongst disease types. Differences in 2yr survival outcomes were not significant among prognostic factors. Specifically, age 60+ vs younger was not prognostic (PFS 24% vs 17% p=0.4, OS 29% vs 29% p=0.7). Likewise, haplo-cord did not differ relative to matched donors in outcomes (PFS 18% vs 26% p=0.2, OS 35% vs 29% p=0.5). Conclusions: Although novel therapeutic approaches are emerging for R/R AML and high risk MDS, allo-SCT remains an established option for long-term disease control. In our analysis, outcomes after in vivo TCD-SCT in R/R AML and high-risk MDS pts treated with RIC mirror published historical results (Duval 2010, Schlenk 2010) but with low rates of cGVHD. The lack of significant difference in survival outcomes amongst age groups and donor sources suggests RIC with in vivo TCD can also be utilized as a platform in older individuals and those with alternative donors. With high relapse rates in this population, better pre-transplant disease reduction, minimal residual disease monitoring and post-transplant maintenance will be critical to increase long-term cures.

Abstract [Introduction] Cytomegalovirus (CMV) infection is a common viral infection in recipients of allogeneic hematopoietic stem cell transplantation (allo-SCT). Early CMV reactivation after allo-SCT is associated with worse non-relapse mortality (NRM) and overall survival (OS). Recently, T-cell replete HLA-haploidentical SCT using post-transplant cyclophosphamide (PTCy-haplo SCT) has been developed and spread rapidly worldwide. Rationale of this strategy is assumed to be selective and cytotoxic depletion of alloreactive T cells which are responsible for graft-versus-host disease (GVHD), while preserving non-alloreactive T cells which can contribute to fight infections. However, recent studies showed that PTCy-haplo SCT was associated with the increased incidence of CMV infection. Letermovir (LET), a novel anti-CMV agent, which inhibits the CMV DNA terminase complex, was approved for the prevention of CMV reactivation in allo-SCT recipients in 2018 in some countries including Japan based on the result of a phase 3 trial. Our facility performs LET prophylaxis in allo-SCT recipient if either donor or recipient is seropositive CMV. Although LET is effective for the prevention of CMV reactivation in allo-SCT recipients, the clinical effectiveness of LET prophylaxis in PTCy-haplo SCT is not well elucidated. Based on these things, we retrospectively evaluated the efficacy of LET prophylaxis in PTCy-haplo SCT. [Methods] We retrospectively analyzed consecutive 99 recipients who received PTCy-haplo SCT at Hokkaido University Hospital from March 2013 to March 2021. We compared the cumulative incidence of CMV reactivation between the LET prophylaxis group (LET group, 33 patients) and LET non-prophylaxis group (non-LET group, 66 patients). LET was initiated on the day 0 at a dosage of 480mg daily. All patients were monitored for CMV reactivation by using the anti-CMV pp65 monoclonal antibody HRP-C7 assay at least once a week from the time of engraftment. CMV reactivation was defined as the detection of CMV antigen positive cells per 50000 white blood cells, whereas CMV disease was defined by organ dysfunction attributable to CMV. [Results] As baseline patient's characteristics were summarized in Table1, there were no difference between LET and non-LET group in terms of age, sex, underlying disease, disease risk at transplantation, prior transplantation, conditioning intensity, and CMV serostatus. All patients received peripheral blood stem cell transplantation. GVHD prophylaxis consisted of Cy (40-50 mg/kg on day 3 and 4), tacrolimus (from day 5), and mycophenolate mofetil (from day 5). The cumulative incidence of CMV reactivation at 150 days after transplantation in LET group was significantly lower than that in non-LET group (30.3% versus 69.7%; P &lt;.001, Figure1A). Importantly, CMV disease were occurred in three patients without LET prophylaxis (gastritis, enteritis, and retinitis), but not in the patients with LET prophylaxis. The cumulative incidence of NRM at 1 year was similar between the patients with and without LET prophylaxis (17.6% versus 9.2%; P=0.366, Figure1B), as was OS at 1 year (71.5% versus 69.4%; P=0.801, Figure1C). Neutrophil engraftment was achieved in 32 patients (97%) at a median of 15 days in LET group and 64 patients (97%) at a median of 14.5 days in non-LET group (P=0.243). Furthermore, platelet engraftment was achieved in 26 patients (79%) at a median of 34 days in LET group and 57 patients (86%) at a median of 31 days in non-LET group (P=0.282). These findings suggest that LET does not affect engraftment. Interestingly, the length of hospitalization in the LET group was significantly shorter than that in non-LET group (the median, 59.5 days versus 71 days; P=0.0488), suggesting that LET suppresses CMV reactivation leading to early discharge. [Conclusion] To our best knowledge, this is the largest retrospective study about the efficacy of LET in PTCy-Haplo SCT. LET is effective for prevention of CMV reactivation in PTCy-haplo SCT.

Abstract Introduction. Malignant diseases treated with allogeneic hematopoietic stem cell transplantation (alloHSCT) predominantly occur beyond the 7 th decade of life. Numerical age per se is not regarded an adverse risk factor in alloHSCT. In an aging society, interventions historically deemed high risk are increasingly used in elder patients. Methods. Epidemiology, outcomes and risk factors of patients aged ≥70 years undergoing alloHSCT in Germany 1999-2019 and registered with the DRST/EBMT database were analyzed retrospectively. Baseline patient, disease, and transplant data were collected from MED-A forms. Centers were contacted to provide additional treatment and follow-up information. Results. Between 1999 and 2019, 1648 patients aged ≥70 years (median 72, range 70-79.7; 585 female) were transplanted in 50 German centers. More than 90% of all patients were transplanted 2010-2019. Centers transplanted between 2 and 192 patients, with 14 centers contributing &lt;10 and 4 centers contributing &gt;100 patients each. Most patients suffered acute leukemia (1084, 65.8%) or MDS/MPN (410, 24.9%). Karnofsky index before start of conditioning was 100% (n=230, 14%), 90% (n=651, 39.5%), 80% (n=480, 29.1%), 70% (n=94, 5.7%), &lt;70% (n=55, 3.3%). Myeloablative conditioning was chosen in 25.6%. Total body irradiation was used for 305 patients (18.6%). Conditioning contained antithymocyteglobulin in 49.6%. Donors were unrelated for 85.5%. Median donor age was 37 (18-79) years. Patient CMV IgG was positive in 63.1% and the constellation 'negative donor, positive patient' was present in 19.9%. Median overall survival (OS) and disease free survival (DFS) was 408/ 344 days. With a median follow up of 536 days for surviving patients, Kaplan Meier estimates of OS/ DFS were 52.6%/ 48.5% and 40.9%/ 38.6% at 1 and 2 years. In a competing risk analysis, cumulative incidence of non-relapse-mortality (NRM)/ relapse (RI) was 22.2%/ 29.3% at 365 days. Frequency of acute graft versus host disease (GvHD) II-IV was 25.1% and chronic limited/ extended GvHD 11.7%/ 14.8%. Karnofsky performance score, CMV IgG matching, acute and chronic GvHD and stem cell source showed a prognostic impact on OS, DFS, RI and/ or NRM (Table 1). Underlying disease did not impact outcome, neither did age amongst patients at an age of 70-80 years. To compare with outcome in the decade below (60-69 years), an analysis after matching for underlying disease, CMV relation, and Karnofsky index included 2728 patients (each 1364 patients 60-69 and ≥70 years of age). For each year of life, univariate HR for OS and DFS were 1.01 [95%CI 1.001-1.023, p=0.035] and 1.01 [95%CI 0.99-1.02, p=n.s.], respectively, in this matched-pair analysis. The cumulative HR (OS, DFS) for both age groups was 1.16 [95%CI 1.05-1.28, p&lt;0.01] and 1.13 [95%CI 1.02-1.24, p=0.016] for patients ≥70 years. Conclusion. AlloHSCT is increasingly used to treat elder patients in Germany with a sharp increase during the last decade. Age per se is a modest adverse risk factor for adult patients after alloHSCT with slightly increased mortality in patients 70-80 versus those at 60-69. Further research might concentrate on patient selection and further reduction of procedural toxicity. Figure 1 Figure 1.

Abstract BACKGROUND High dose therapy followed by autologous stem cell transplantation (ASCT) remains the standard of care, especially in Europe, for young and eligible multiple myeloma patients (usually younger than 65 years old). Immunoparesis is defined as a reduction (below the lower normal limit) in the levels of 1 or 2 uninvolved immunoglobulins (Ig) and it is related to a reversible suppression of B lymphocytes that correlates inversely with disease stage. B Lymphocyte reconstitution begins at 3 months after ASCT, with maximum B lymphocyte levels at 1 year after ASCT. AIMS The goal of the present study was to investigate the role of the immunoparesis recovery after ASCT as predictor of relapse or progression in multiple myeloma (MM). METHODS We reviewed medical records of MM patients who underwent to ASCT at University Hospital of Salamanca between 1992 and 2013. The primary endpoint was time to relapse or progression from ASCT. Ig (Ig G, Ig A e Ig M) were collected at the time of diagnosis, before ASCT, every 3 months during the first year after ASCT, and every year up to 5 years after ASCT among eligible patients until the relapse or disease progression. RESULTS 106 multiple myeloma patients who underwent ASCT were included in the analysis. Conventional chemotherapy was administered as induction regimen in 69 patients (65%), whereas novel agents were used in 37 patients (35%). Most patients had immunoparesis at diagnosis (91%) and at the moment of ASCT as well (94%). After a median follow-up of 62 months, median time to progression or relapse (TTP) from ASCT was 31 months (95 % CI: 24.1 - 37.1 months). MM patients with immunoparesis 1 year after ASCT had a significantly shorter median TTP as compared with patients without immunoparesis (33.5 months vs 94.2 months; HR: 2.14, 95% CI: 1.13-4.05; p=0.019). In the group of patients with reduction of both Igs, median TTP was slightly inferior than in the group with reduction of only one of them(33.5 vs 36.4 months, p=0.03). Presence of ISS 3, high-risk cytogenetics at diagnosis, less than partial response achieved before and three months after ASCT were also identified as predictors of progression. Multivariate analysis selected immunoparesis 1 year after ASCT as an independent variable for relapse or progression (HR: 5.97, 95% CI: 1.63-21.88; P=0.007). CONCLUSIONS The lack of immunoparesis recovery at 1 year after ASCT in MM patients is associated with significantly higher risk of relapse or progression and this group of patients could potentially benefit of continuous treatment after ASCT to enhance the immune recovery.

Abstract Introduction: Previous trials have shown that autologous stem cell transplantation (ASCT) is superior to conventional chemotherapy in terms of remission rate and PFS in younger MM patients. Concerns about toxicity and potential efficacy of ASCT in older MM patients lead most centers to limit ASCT indications to patients aged <65 years. However, at the era of novel induction regimens, and because of better patient selection and supportive care, ASCT may prove to be a valid treatment option even in older MM patients. Therefore, some investigators are questioning the widely used 65 years age limit. Patients and Methods: We prospectively analyzed the outcomes of 56 consecutive MM patients who had received ASCT between September 2012 and September 2014 in 6 institutions in France (protocol ClinicalTrials.gov Identifier: NCT01671826). Patients were newly diagnosed MM. For induction therapy, all patients received a bortezomib-based induction regimen (VD, VTD, VCD, or VRD, 4 to 6 cycles) according to center's local guidelines. Mobilization was performed with G-CSF or G-CSF+cyclophosphamide and plerixafor whenever needed. High-dose chemotherapy consisted of either 140 mg/m2 or 200 mg/m2 Melphalan. A short two months consolidation phase post ASCT was allowed (lenalidomide-dexamethasone, VD, VTD, VCD or VRD). No maintenance treatment was given. Response, disease progression and relapse were defined according to the IMWG uniform response criteria. All patients signed an informed consent form according to the EBMT guidelines. Results: At time of diagnosis, median age was 67 (range, 64-74) years with 23% of patients being >70 years. There were 30 males and 26 females. The immunoglobulin subtype was IgG (n=29), IgA (n=15), light chain (n=10), other (n=2). The Salmon and Durie stage was III in 89% of cases (n=47), and the ISS score was I (n=18; 35%), II (n=19; 37%), III (n=14; 27%). Patients had high risk cytogenetics features (t(4;14) and/or del17p) in 9 cases (16%). 10% of patients had a serum creatinine level >176 micromol/L. None of the patients underwent hemodialysis. The Sorror comorbidity score was 0 (34), 1 (6), 2 (2), 3 (6), 6 (1), unknown (7). The median age at time of ASCT was 68 years, and the median time from diagnosis to ASCT was 5 months. In an intention to treat analysis, out of 56 patients, 6 patients could not proceed to ASCT because of an early infectious death (n=1), serious comorbidity (n=2), disease refractoriness to induction (n=1), and failure to collect an adequate PBSC graft (n=2). A median of 5.31x106/Kg CD34+ cells could be collected. Disease status at time of ASCT was: CR (n=12; 24%), VGPR (n=19; 38%), PR (n=17; 34%), and SD/non-responding (n=2; 4%). The conditioning regimen consisted of 140mg/m² melphalan in 18 cases (36%) and 200mg/m2 in 32 patients (64%). Moreover, 4 patients (8%) received a tandem ASCT. The median time for neutrophils and platelets engraftment was 12 days. The day-100 post ASCT non-relapse mortality was 0% and the 2-year NRM was 4.2% (95% CI:[0.3-18.3]). The overall response rate at day 100 was 96% (CR: 34%, VGPR: 47%, PR: 15%, SD/non-responsive: 4%). At 3 months post ASCT, 82% patients were able to receive the planned post ASCT consolidation treatment. After a median follow-up of 12 months, the estimated progression-free (PFS) and overall survival (OS) rates at 2 years were 76% (95%CI: [61.6-94.1]) and 88% (95%CI: [76.7-100]), respectively. The incidences of infectious complications post ASCT, and response rates were comparable between the two melphalan dose levels (p=0.28). However, in the univariate analysis, the 200 mg/m2 melphalan conditioning group showed a better OS rate compared to the 140 mg/m2 group (1-year OS: 100% vs. 67%; p=0.012). Conclusion: These prospective multicenter results indicate that ASCT is a safe and effective treatment modality for elderly, but fit MM patients at the era of novel induction agents. Of note, patients above age 70 did not experience a worse prognosis. Thus, age per se should not be used as an exclusion criterion for ASCT. Longer follow-up data will be presented, but these results already set the frame for a randomized comparison to the non-transplant approaches in this patients' subgroup.

Safety And Efficacy

Introduction Multiple myeloma (MM) patients with renal impairment (RI), especially dialysis-dependent (DD) RI, have poorer outcomes than MM patients with normal renal function. Autologous stem cell transplantation (ASCT) is a treatment option, but there is concern at a perceived higher risk of complications which may be limiting consideration of the use of ASCT in this population. The evidence is inconsistent among studies and interpretation is complicated by heterogeneous datasets, some dating to before the availability of novel agents. Finally, the reversibility of RI following ASCT is an important prognostic factor for both survival and quality of life. Aim To evaluate the safety and efficacy of ASCT in MM patients with DD RI transplanted in EBMT centres between 1997 and 2017. Methods Baseline characteristics at diagnosis, patient treatment regimens and clinical outcomes were collected using standardised report forms. OS was defined as the period between the date of ASCT and the date of death or the date of last observation. PFS was defined as the period between the date of ASCT and date of progression/relapse or death of any causes or the date of the last observation. Cox proportional hazard regression analysis was applied to assess risk factors for progression and death. Survival curves were plotted by the Kaplan-Meier method and compared using log-rank test. P&lt;0.05 was judged as statistically significant. Results A total of 109,959 adult MM patients are registered in the EBMT database as having undergone ASCT between 1997 and 2017. We further analysed 118 DD MM patients who had a first ASCT during this period. The median (range) age was 57 (27-71) years. Seventy (59%) patients were males. Forty nine patients (49/94 patients, 52%) had Karnofsky score ≥90. One hundred and ten patients were treated with hemodialysis and eight with peritoneal dialysis. A total of 68 (58%) patients had Light Chain MM, 43 kappa and 25 Lambda. In first-line induction therapy, 47/76 (62%) patients received bortezomib-based regimens. Forty-four (37%) patients achieved at least VGPR pre-ASCT. The median time from diagnosis to ASCT was 0.7 years (0.3-4.9). Melphalan doses were as follows: 140 mg/m2 (n=55, 67%), 70-100 mg/m2 (n=15, 18%), and &gt;140 mg/m2 (n=12, 15%). The times to Neutrophil (&gt;0.5) and Platelet (&gt;20) engraftment were 12 (10-37) and 14 (4-128) days, respectively. The 30-day and 100-day transplant-related mortality (TRM) rates were 0.0% and 0.9%, respectively. ASCT was associated with a significant deepening of response (at least VGPR pre- vs post-ASCT: 36/93 (39%) vs 48/93 (52%), p &lt; 0.001). The median PFS was 37 months (95% CI: 24-43) and 5-year PFS was 31% (95% CI: 20-41). The median OS was 102 months (95% CI: 67-129). Five-year OS post-ASCT was 62% (52-72) and 10-year OS 36% (17-55). Thirty-one (26%) DD MM patients achieved dialysis independence. There were no differences in PFS or OS when comparing the 1997-2007 and 2008-2017 cohorts: 5-year PFS - 28% (6-49) vs 31% (19-43) (p=0.7) and 5-year OS - 61% (38-84) vs 63% (51-74) (p=0.9), respectively. On univariate analysis of factors affecting PFS, achievement of an Overall Response Rate (ORR) (CR+VGPR+PR vs. Other) pre-ASCT was associated with a lower risk (HR 0.467, p=0.032) and older age (&gt;55 years) with a higher risk (HR 1.786, p=0.035) of post-ASCT progression. Age higher than 55 (HR 2.033, 95%CI: 0.992 - 4.166, p=0.053) increased and achievement of at least VGPR pre-transplant (HR 0.494, 95%CI: 0.224 - 1.091, p=0.081, on the verge of statistical significance) decreased the risk of death. Conclusion To the best of our knowledge, the DIADEM study is the largest analysis of ASCT in DD MM pts to date. This cohort of 118 unselected patients had an OS comparable to patients without RI. This may reflect patient selection based on younger age, Karnofsky scores and pre-ASCT response. The low TRM and excellent outcomes support consideration of the use of ASCT in pts with DD RI. Notably, more than a quarter of patients became dialysis independent, an outcome likely to confer an improved Quality-of-Life.. These results can also inform the debate around the role of renal transplantation in younger DD MM patients who do not achieve dialysis independence.

Abstract Introduction: Hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT) is performed to treat hematologic malignancies such as acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), multiple myeloma (MM), chronic lymphocytic leukemia (CLL), chronic myeloid leukemia (CML), myelodysplastic syndrome (MDS), lymphomas (HL and NHL) and hemophagocytic lymphohistiocytosis (HLH). Inpatient data on the characteristics of patients receiving BMT, the distribution of BMT among the above mentioned hematological cancers and their outcomes is lacking. This study analyzes patient and hospital characteristics of patients undergoing BMT, in addition the study describes resource utilization and outcomes of BMT among various hematological cancers. Methods: We performed a retrospective cohort analysis of the National Inpatient Sample 2014 Database (HCUP-NIS). Patients were included in the study if they had a procedure diagnosis of BMT and a medical diagnosis of acute or chronic leukemia (ALL, AML, CLL, CML), lymphoma (HL and NHL), MM, MDS or HLH. HSCT or BMT includes both Allogeneic and Autologous Stem Cell Transplant however we did not differentiate one from the other since BMT in MM is almost universally auto stem cell transplantation. We performed descriptive statistics to characterize the cohort in terms of personal demographic factors (age, race, sex, insurance type, community level income level), indication for HSCT, hospital characteristics (size, region, teaching status, and urban or rural location), and timing of admission (weekend or weekday). We performed univariate analyses using these variables to determine the associations with LOS and mortality. All analyses apply the HCUP-NIS weights. Results: The cohort comprised of 18,275 patients who underwent HSCT. Most patients were male (59.1%), white (70.4%), aged 51-70 years (53.9%), and covered by private insurance (57.0%). Nearly a third (31.3%) lived in communities with the highest quartile of household incomes. The most common diagnosis associated with HSCT was MM (27.6%), followed by AML (15.6%). Most HSCT was performed at large hospitals (74.5%); only 0.1% were performed in rural and 1.1% at non-teaching hospitals. Average length of stay (ALOS) was 25.54 days (95% CI 24.19 to 26.89) and the mean total charges (per hospitalization) were $346,555 (95% CI $310,465 to $382,645) and net charge was $6.33 billion. Several factors were associated with lower ALOS: age (AMD -0.31, 95% CI -0.37 to -0.24), Charlson index (AMD -0.85, 95% CI -1.60 to -0.12), private insurance coverage (AMD -3.65, 95% CI -5.25 to -2.067) and self pay status (AMD -13.56, 95%CI -17.13 to -10.00). Urban (AMD 6.74, 95% CI 1.01 to 12.48), and teaching hospitals (AMD 8.31 95% CI 2.88 to 13.72) had longer ALOS. Only Hispanic race (OR 0.23 95% CI 0.068 to 0.77) and Charlson index (OR 1.2 95% CI 1.04 to 1.39) were associated with mortality. Multivariate analysis did not show any significant associations of mortality with age, race, geographic region, hospital size, median household income, type of insurance, timing of admission, or teaching or location status of hospitals. Discussion: MM accounted for the most significant portion of HSCT in 2014, although its incidence is lower than that for leukemia and lymphoma. This may partly be because autologous stem cell transplantation (ASCT) after high dose chemotherapy is the mainstay of MM treatment. In contrast to other hematological malignancies, some MM patients may also undergo tandem transplantation. Most HSCT recipients were covered under private insurance, and a significant proportion of them came from communities with the highest quartile of median household incomes. This suggests that socioeconomic status influences access to HSCT therapy, likely related to out of pocket costs. In addition, social determinants of health including health literacy, access to health care may play a role. Surprisingly, ALOS decreased with increasing age and Charlson comorbidity index. Reasons are unclear but may be related to increased or earlier mortality. Additional studies could help to elucidate this relationship. Figure. Figure.
