Abstract
In the present study, reduced toxicity (FluBu3) and myeloablative (BuCy) conditioning were compared in patients with AML who received first allogeneic HSCT in MRD-negative CR1. The study included 124 adult patients who underwent HSCT from an HLA-matched (8/8) sibling, unrelated, or 1-locus mismatched (7/8) unrelated donor (MMUD). The median age was 45 years and intermediate cytogenetics comprised majority (71.8%). The 2-year OS, RFS, CIR and NRM for BuCy (n = 78, 62.9%) and FluBu3 (n = 46, 37.1%) groups were 78.3% and 84.5% (p = 0.358), 78.0% and 76.3% (p = 0.806), 7.7% and 21.5% (p = 0.074) and 14.3% and 2.2% (p = 0.032), respectively. At the time of data cut-off, relapse and NRM were the main causes of HSCT failure in each of the FluBu3 and BuCy arms. Among patients, 75% of relapsed FluBu3 patients had high-risk features of either poor cytogenetics or FLT3-ITD mutation compared with 16.7% of BuCy patients. The majority of NRM in the BuCy group was due to GVHD (73%), half of whom received MMUD transplantation. To conclude, the FluBu3 reduced toxicity conditioning showed comparable post-transplant OS and RFS to BuCy and was associated with significantly reduced NRM that was offset by a trend towards higher risk of relapse even in MRD-negative CR1 population.

Abstract
BACKGROUND Bortezomib-melphalan-prednisone (VMP) and lenalidomide-dexamethasone (Rd) remain the standard treatments for transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). This study aimed to compare real-world benefits between the two regimens. We also were interested in exploring efficacy according to subsequent therapy following VMP or Rd. METHODS A total of 559 NDMM patients treated with VMP (n = 443, 79.2%) or Rd (n = 116, 20.8%) was recruited retrospectively from a multicenter database. RESULTS Rd provided more benefits than VMP-overall response rate: 92.2 vs. 81.8%, p = 0.018; median progression-free survival (PFS): 20.0 vs. 14.5 months, p <0.001; second PFS (PFS2): 43.9 vs. 36.9 months, p = 0.012; overall survival (OS): 100.1 vs. 85.0 months, p = 0.017. Multivariable analysis revealed significant benefits of Rd over VMP, with hazard ratios of 0.722, 0.627, and 0.586 for PFS, PFS2, and OS, respectively. In propensity score-matched cohorts with matched VMP (n = 201) and Rd (n = 67) arms to balance baseline characteristics, Rd still showed significantly better outcomes for PFS, PFS2, and OS than VMP. Following VMP failure, triplet therapy showed significant benefits for response and PFS2; after Rd failure, PFS2 with carfilzomib-dexamethasone was significantly better than bortezomib-based doublet treatment. CONCLUSION These real-world findings may assist with better selection between VMP and Rd as well as subsequent therapy for NDMM.

Abstract
PURPOSE Autologous hematopoietic stem cell transplantation (ASCT) has been introduced as a standard treatment for newly diagnosed multiple myeloma (NDMM) following novel agent-based induction chemotherapy. This study investigated whether pre-ASCT low muscle mass evaluated using the paraspinal muscle index (PMI) at the 12th thoracic vertebra (T12) level is a reliable prognostic marker in NDMM after chemotherapy. METHODS A multi-center registry database was retrospectively analyzed. Between 2009 and 2020, 190 patients with chest computed tomography images underwent frontline ASCT following induction therapy. The PMI was defined as the value of the paraspinal muscle area at the T12 level divided by the square of the patient's height. The cut-off value indicating a low muscle mass was sex-specific, using the lowest quintiles. RESULTS Of the 190 patients, 38 (20%) were in the low muscle mass group. The low muscle mass group had a lower 4-year overall survival (OS) rate than the non-low muscle mass group (68.5% vs. 81.2%; P = 0.074). The median progression-free survival (PFS) in the low muscle mass group was significantly shorter compared with the non-low muscle mass group (23.3 months vs. 29.2 months; P = 0.029). The cumulative incidence of transplant-related mortality (TRM) was significantly higher in the low muscle mass group than in the non-low muscle mass group (4-year probability of TRM incidence, 10.6% vs. 0.7%; P < 0.001). In contrast, no significant difference in the cumulative incidence of disease progression was found between the two groups. Multivariate analysis revealed that low muscle mass was associated with significant negative outcomes for OS [(hazard ratio (HR): 2.14; P = 0.047], PFS (HR: 1.78; P = 0.012), and TRM (HR: 12.05; P = 0.025). CONCLUSION Paraspinal muscle mass may have a prognostic role in NDMM patients who undergo ASCT. Patients with low paraspinal muscle mass have lower survival outcomes compared to non-low muscle mass group.

Abstract
Optimal first-line treatment that enables deeper and longer remission is crucially important for newly diagnosed multiple myeloma (NDMM). In this study, we developed the machine learning (ML) models predicting overall survival (OS) or response of the transplant-ineligible NDMM patients when treated by one of the two regimens-bortezomib plus melphalan plus prednisone (VMP) or lenalidomide plus dexamethasone (RD). Demographic and clinical characteristics obtained during diagnosis were used to train the ML models, which enabled treatment-specific risk stratification. Survival was superior when the patients were treated with the regimen to which they were low risk. The largest difference in OS was observed in the VMP-low risk & RD-high risk group, who recorded a hazard ratio of 0.15 (95% CI: 0.04-0.55) when treated with VMP vs. RD regimen. Retrospective analysis showed that the use of the ML models might have helped to improve the survival and/or response of up to 202 (39%) patients among the entire cohort (N = 514). In this manner, we believe that the ML models trained on clinical data available at diagnosis can assist the individualized selection of optimal first-line treatment for transplant-ineligible NDMM patients.

Abstract
Background The goal of induction therapy for multiple myeloma (MM) is to achieve adequate disease control. Current guidelines favor triplet (bortezomib-lenalidomide-dexamethasone; VRd) or quadruplet regimens (daratumumab, bortezomib-thalidomide-dexamethasone; D-VTd). In the absence of a direct comparison between two treatment regimens, we conducted this study to compare the outcomes and safety of VRd and D-VTd. Methods Newly diagnosed MM patients aged >18 years who underwent induction therapy followed by autologous stem cell transplantation (ASCT) between November 2020 and December 2021 were identified. Finally, patients with VRd (N=37) and those with D-VTd (N=43) were enrolled. Results After induction, 10.8% of the VRd group showed stringent complete remission (sCR), 21.6% showed complete response (CR), 35.1% showed very good partial response (VGPR), and 32.4% showed partial response (PR). Of the D-VTd group, 9.3% showed sCR, 34.9% CR, 48.8% VGPR, and 4.2% PR (VGPR or better: 67.6% in VRd vs. 93% in D-VTd, P=0.004). After ASCT, 68.6% of the VRd group showed CR or sCR, while 90.5% of the D-VTd group showed CR or sCR (P=0.016). VRd was associated with an increased incidence of skin rash (P=0.044). Other than rashes, there were no significant differences in terms of adverse events between the two groups. Conclusion Our study supports the use of a front-line quadruplet induction regimen containing a CD38 monoclonal antibody for transplant-eligible patients with newly diagnosed MM.

Abstract
Newly diagnosed multiple myeloma (NDMM) frequently results in renal impairment (RI), and its natural course has not been fully elucidated in the era of novel agents. We aimed to identify the dynamics of renal function after autologous stem cell transplantation (ASCT) following induction treatment using a novel agent in transplantation-eligible NDMM patients with RI (estimated glomerular filtration rate [eGFR] ≤50 mL/min/1.73 m2) at diagnosis. The factors associated with achieving a renal response based on the term renal benefit regardless of baseline eGFR were investigated as well. In a multicenter registry database including 1795 patients with plasma cell disorder, 140 transplantation-eligible NDMM patients who developed RI at the time of initiation of treatment for NDMM were identified. They received protocol-based treatment (PBT) consisting of induction treatment using proteasome inhibitors and/or immunomodulatory drugs followed by ASCT. MM and renal responses were evaluated using the International Myeloma Working Group response criteria. To evaluate the standardized improvement of renal function irrespective of baseline eGFR, renal benefit was defined as a sustained (for at least 3 months) increase in eGFR >15 mL/min/1.73 m2. The mean patient age was 54.7 ± 7.4 years. With a mean baseline eGFR of 24.8 ± 13.9, the renal complete response (renalCR) and renal benefit rates were 49.3% and 67.9%, respectively. In a multivariable analysis, the 3 factors significantly associated with reduced likelihood of achieving both renalCR and renal benefit were age ≥55 years, light chain type NDMM, and failure to improve eGFR by 5 mL/min/1.73 m2 with supportive care when measured 3 days prior to induction therapy and at the initiation of chemotherapy. Hypertension and advanced eGFR also were associated with poor renalCR achievement. The mean eGFR improved until the time of ASCT and then decreased gradually over time. The mean eGFR improved significantly until 4 months post-PBT compared with each eGFR at previous time points, but this significant improvement disappeared by 5 months post-PBT. In a subgroup of patients who developed RI after undergoing ASCT (n = 55), the eGFR increased temporarily at 1 month post-ASCT; however, this improvement reverted to baseline at 2 months post-ASCT. Among another subgroup of 27 patients who were dialysis-dependent at the time of initial treatment, 18 (66.7%) were no longer dialysis-dependent after a median of 60 days. The best renal response was acquired early during the PBT period, and ASCT did not have a robust impact on the renal outcome. Patients who failed to achieve a renal benefit should be provided with the best supportive care for chronic kidney disease, and this simplified criterion for evaluating the renal response needs to be validated in larger studies before it can be recommended. © 2022 American Society for Transplantation and Cellular Therapy.

Abstract
Background Arsenic trioxide (ATO) is the standard treatment for relapsed acute promyelocytic leukemia (APL). However, consensus on post-remission therapies is still lacking. Methods We evaluated 52 patients who experienced relapse following initial treatment of APL between 2000 and 2019 at Catholic Hematology Hospital. Among them, 41 patients received reinduction treatment, 30 with ATO-based regimen, whereas 11 with conventional intensive chemotherapy (IC). Results The ATO reinduction group showed a significantly higher second molecular complete remission (mCR2) rate, superior neutrophil and platelet recovery, and a lower infection rate than the IC reinduction group. No significant differences were observed in survival outcomes after post-remission treatment among the ATO-based (N=19), autologous (N=12), and allogeneic (N=6) hematopoietic stem cell transplantation (HSCT) groups. In the ATO-based and autologous HSCT groups, among patients with mCR2 after ATO reinduction, nine and five patients experienced a second relapse, respectively (50.7% vs. 41.7%, P=0.878). Among these patients, seven received salvage allogeneic HSCT; six remained alive. The other seven patients received ATO without HSCT. Five died from disease progression, and two survived and have been in mCR2 since. Conclusion Post-remission treatment outcomes of patients with relapsed APL were not significantly different, regardless of the treatment option, suggesting the feasibility of ATO-based treatment without HSCT in mCR2. Allogeneic HSCT may be an effective salvage treatment modality for patients with a second relapse. Owing to a few cases of relapsed APL, multicenter prospective studies may help elucidate the efficacy of each post-remission treatment.

Abstract
Background: Evidence that a venetoclax (VEN)-combined regimen is effective in relapsed/refractory acute myeloid leukemia (R/R AML) is emerging. However, it is unknown how VEN-combined low intensity treatment compares to intensive chemotherapy (IC) in medically fit patients with R/R AML. Methods: We compared AML patients who received IC (n = 89) to those who received a VEN in combination with hypomethylating agents or low dose cytarabine (VEN combination) (n = 54) as their first- or second-line salvage after failing anthracycline-containing intensive chemotherapy. Results: The median age was 49 years, and significantly more patients in the VEN combination group were in their second salvage and had received prior stem cell transplantation (SCT). Overall response rates including CR, CRi, and MLFS were comparable (44.0% for IC vs. 59.3% for VEN combination, p = 0.081), but VEN combination group compared to IC group tended to show lower treatment related mortality. The rate of bridging to SCT was the same (68.5%), but the percentage of SCT at blast clearance was significantly higher in the VEN-combined group (62.3% vs. 86.5%, p = 0.010). After median follow-up periods of 22.5 (IC) and 11.3 months (VEN combination), the median overall survival was 8.9 (95% CI, 5.4-12.4) and 12.4 months (95% CI, 9.5-15.2) (p = 0.724), respectively. Conclusion: VEN combination provides a comparable anti-leukemic response and survival to salvage IC, and provide a bridge to SCT with better disease control in medically-fit patients with R/R AML.

Abstract
Purpose The significance of Epstein-Barr virus (EBV) infections for the prognosis of patients with peripheral T-cell lymphomas (PTCLs), specifically angioimmunoblastic T-cell lymphoma (AITL) and PTCL not otherwise specified (PTCL-NOS), remains unclear. The Epstein-Barr encoding region can be used to detect EBV in tissue sections by in situ hybridization (ISH) and by polymerase chain reaction (PCR) assays of peripheral blood samples from patients with PTCLs. This study compared the outcomes patients with AITL or PTCL-NOS for whom the presence of EBV infection was assessed by these two methods. Patients and Methods This was a retrospective study of patients newly diagnosed with AITL or PTCL-NOS. All patients were selected from a single transplantation center. EBV-positive lymphomas were detected at the time of diagnosis in tissue sections by ISH or in the blood by PCR. Results Out of a cohort of 140 patients with histologically confirmed AITL or PTCL-NOS, 105 were EBV-positive. The 3-year overall survival of patients with EBV-positive TCL was 43.3% compared to 68.6% in patients with EBV-negative TCL (p = .01). Patients who were treated with autologous or allogeneic hematopoietic stem cell transplantation (n = 28 and n = 11, respectively) or chemotherapy alone (n = 66) had 3-year survival rates of 67.0%, 62.3%, and 30.2%, respectively (p <.02). Patients with EBV-positive TCL had a better prognosis after treatment with hematopoietic stem cell transplantation compared to chemotherapy alone, but no difference was seen among patients with EBV-negative TCL. Conclusions EBV infection was shown to negatively affect the clinical outcomes of patients with TCL. Stem cell transplantation has been found to be an effective treatment for EBV-associated lymphomas. Further investigations are warranted to determine the optimal treatment for these patients.

Abstract
INTRODUCTION Donor lymphocyte infusion (DLI) is one of the effective options for post-transplant disease control of myelodysplastic syndrome (MDS). Its success or failure depends on the induction of antitumor immune reactions, durability of clinical responses, and severity of unwanted toxicities mainly from graft-versus-host disease (GVHD). METHODS By analyzing 61 patients receiving DLI for post-transplant MDS relapse, we assessed treatment outcomes and affecting factors, especially focusing on the level of relapse (hematological, molecular, and imminent relapse). RESULTS The response rate (42.1%, 36.4%, 72.7%), and overall survival (OS) at 2 years (27.8%, 45.5%, 70.1%) were different for each relapse level with imminent relapse group showing the most promising results. For OS, response to DLI or pre-DLI chemotherapy, and time to relapse were independent prognostic factors. Meanwhile, post-DLI GVHD and time to relapse were independently predictive for DLI response; post-DLI GVHD was predictive for DLI response, but not for OS, suggesting a potential detrimental impact of GVHD on survival. The incidence of GVHD and GVHD-related deaths were 37.7% and 10.0%, respectively, and CD3+ cell doses triggering GVHD tended to be lower in cases with haploidentical donor or imminent relapse. CONCLUSION Despite being limited by small number of cases and its retrospective nature, this study again demonstrated the therapeutic effects of DLI in relapsed MDS, and that earlier detection and intervention at lower level relapse might possibly be associated with better results. Furthermore, we propose that tailored cell dosing schedule based on relapse level and donor source may be helpful in minimizing fatal GVHD.

Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) remains the most effective postremission therapy conferring the chance of cure for acute myeloid leukemia (AML), including elderly patients. Although the number of transplantations for elderly patients with AML (eAML) is increasing owing to greater availability of various graft sources together with the adoption of advanced supportive care and reduced-intensity conditioning (RIC) regimen, there are relatively limited data on the impact of donor type in eAML compared to younger patients. In addition, few studies have evaluated the role of pretransplantation measurable residual disease (MRD) in the elderly population. Given the lack of prospective comparative study, we retrospectively compared transplantation outcomes of elderly patient with AML receiving allo-HSCT from matched sibling donor (MSD-HSCT), matched unrelated donor (MUD-HSCT) or haploidentical related donor (Haplo-HSCT), or autologous HSCT (Auto-HSCT). A total of 154 patients with a median age of 63 years (range 60-74) underwent MSD-HSCT (n = 41), MUD-HSCT (n = 36), Haplo-HSCT (n = 55), or Auto-HSCT (n = 22) for AML. RIC regimens were used in the majority of patients. In Haplo-HSCT, T-cell-replete peripheral blood stem cells with unique RIC regimens using anti-thymocyte globulin (ATG)-based GVHD prophylaxis was used. In the analysis, adjustment for MRD status at the time of transplantation was performed. MRD was measured by the quantitative molecular assays of the targets, including RUNX1-RUNX1T1, CBFB-MYH11, and NPM1, or WT1 in the absence of abnormalities in the aforementioned targets. At a median follow-up of 48 months, survival rates were similar between different donor types, whereas nonrelapse mortality (NRM) was lower in MUD-HSCT compared to MSD-HSCT (P = .002). MSD-HSCT, in which the majority of patients received a conditioning regimen not including ATG, showed more frequent severe chronic graft-versus-host disease (cGVHD). The major causes of non-relapse deaths in MSD-HSCT were related to cGVHD (71%), whereas infectious complications were mainly related to NRM in Haplo-HSCT (50%) or Auto-HSCT (100%). In the MUD-HSCT, GVHD (57%) and infection (43%) contributed similarly to non-relapse death. Cytomegalovirus infection was more frequent in Haplo-HSCT. In multivariate models, pre-transplant MRD-positivity was an independent risk factor for relapse (P = .001), whereas older age (P = .002) and the hematopoietic cell transplantation-comorbidity index (P = .009) were useful in predicting NRM. The current study demonstrated comparable outcomes after alternative and matched sibling donor HSCT in eAML aged 60 years or older, and the results also suggest the necessity for more sophisticated strategies to reduce NRM or relapse according to each donor type. The usefulness of molecular MRD assays demonstrated herein will facilitate trials for MRD-driven decision-making or risk-adaptive approaches in eAML.

Abstract
BACKGROUND/AIMS Idiopathic multicentric Castleman disease (iMCD) comprises approximately 30% of all cases of Castleman disease. It is characterized by constitutional symptoms, enlarged lymph nodes at multiple anatomical sites, and laboratory test abnormalities, which are primarily related to the overproduction of interleukin 6 (IL-6). Siltuximab is a human-mouse chimeric immunoglobulin G1κ monoclonal antibody against human IL-6. In view of the limited treatment options for iMCD, this study aimed to evaluate the efficacy and safety of siltuximab in the management of this condition. METHODS In this real-world retrospective study, we administered siltuximab to 15 patients with iMCD who previously received conventional chemotherapy and/or steroid pulse therapy. The median time to a durable symptomatic response was 22 days (range, 17 to 56). The serum hemoglobin and albumin levels and erythrocyte sedimentation rates significantly normalized after the first 3 months of siltuximab treatment. Lymph node involution, assessed using imaging, was relatively gradual, demonstrating a complete or partial response at 6 months. RESULTS On an average, the improvements in clinical, laboratory, and radiologic parameters of iMCD in responders were observed after one, three, and eight cycles of siltuximab treatment, respectively. Siltuximab demonstrated a favorable safety profile, and prolonged treatment was well-tolerated. CONCLUSION Despite the small sample size of the present study, the results are encouraging and demonstrate the potential of siltuximab as the first-line treatment of iMCD. Further large multicenter studies are needed to evaluate the clinical outcomes and adverse events associated with siltuximab.

Abstract
Simple Summary Acute myeloid leukemia (AML) with RUNX1-RUNX1T1 is a heterogeneous disease entailing different prognoses. Patients with high-risk features can benefit from allogeneic hematopoietic stem cell transplantation (HSCT) or autologous HSCT. However, insufficient data about major risk factors, such as KIT mutations and measurable residual disease (MRD) status for relapse, make it difficult to clarify the benefit of each transplant strategy. Moreover, limited data are available to elucidate the exact prognostic impacts of different types of KIT mutations and optimal thresholds or time points for RUNX1–RUNX1T1 MRD assessment, particularly in the setting of HSCT. Given the lack of prospective study, the current retrospective study, including a large cohort of high-risk AML patients with RUNX1–RUNX1T1, firstly demonstrated the differentiated prognostic impact of D816V KIT mutation among various KIT mutations and clarified optimal time points and thresholds for RUNX1–RUNX1T1 MRD monitoring in the setting of HSCT. Abstract The prognostic significance of KIT mutations and optimal thresholds and time points of measurable residual disease (MRD) monitoring for acute myeloid leukemia (AML) with RUNX1-RUNX1T1 remain controversial in the setting of hematopoietic stem cell transplantation (HSCT). We retrospectively evaluated 166 high-risk patients who underwent allogeneic (Allo-HSCT, n = 112) or autologous HSCT (Auto-HSCT, n = 54). D816V KIT mutation, a subtype of exon 17 mutations, was significantly associated with post-transplant relapse and poor survival, while other types of mutations in exons 17 and 8 were not associated with post-transplant relapse. Pre- and post-transplant RUNX1–RUNX1T1 MRD assessments were useful for predicting post-transplant relapse and poor survival with a higher sensitivity at later time points. Survival analysis for each stratified group by D816V KIT mutation and pre-transplant RUNX1–RUNX1T1 MRD status demonstrated that Auto-HSCT was superior to Allo-HSCT in MRD-negative patients without D816V KIT mutation, while Allo-HSCT was superior to Auto-HSCT in MRD-negative patients with D816V KIT mutation. Very poor outcomes of pre-transplant MRD-positive patients with D816V KIT mutation suggested that this group should be treated in clinical trials. Risk stratification by both D816V KIT mutation and RUNX1–RUNX1T1 MRD status will provide a platform for decision-making or risk-adapted therapeutic approaches.

Abstract
Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) after one cycle of standard chemotherapy in patients with diffuse large B cell lymphoma (DLBCL) was assessed. Prospectively enrolled 51 patients had four PET/CT studies using the same protocol and system: at baseline and after one, three, and six cycles of chemotherapy (PET0, PET1, PET3, PET6). The PET1 and PET6 Deauville five-point score (D5PS) agreed in 60.8%, while PET3 and PET6 D5PS agreed in 90.2%. The absolute and percent changes of peak standard uptake value corrected for lean body mass (SULpeak) compared to baseline were significantly different between PET1 and PET3 (p = 0.001, p < 0.001) and PET1 and PET6 (p = 0.002, p = 0.001), but not between PET3 and PET6 (p = 0.276, p = 0.181). The absolute SULpeak from PET1 predicted treatment failure with accuracy of 78.4% (area under the curve 0.73, p = 0.023). D5PS, SULpeak, and metabolic tumor volume (MTV) were not statistically different between responders versus non-responders, or the one year disease-free versus relapse groups. D5PS and PERCIST responses showed 100% agreement at end-of-therapy. In conclusion, the responses after three and six cycles of therapy showed high degree of agreement. D5PS or MTV after one cycle of chemotherapy could not predict response or one-year disease-free status, but the SULpeak from PET1 was associated with response to first line therapy in DLBCL. Deauville and PERCIST criteria show high concordance.

Abstract
Relapse is a major concern with reduced-intensity conditioning. We analyzed 257 patients with acute myeloid leukemia (AML) who received allogeneic stem cell transplantation (SCT) and fulfilled the following criteria: intermediate- or poor-risk disease by National Comprehensive Cancer Network guidelines (2017, version 3), in first complete remission (CR1) at SCT, received either myeloablative conditioning (MAC; busulfan plus cyclophosphamide or cyclophosphamide plus total body irradiation) or reduced-intensity conditioning (RIC; FluBu2TBI400) peripheral blood SCT from 8/8 matched sibling or unrelated donor, and having bone marrow Wilms tumor gene 1 (WT1) expression results before transplant. We and other groups serially published a predictive value for pretransplant WT1 expression in patients with AML to identify patients at higher risk of relapse. Among the total 257 patients, 191 (74.3%) and 66 (25.7%) patients received MAC and RIC transplants, respectively. WT1 ≥250 copies/104ABL was defined as WT1high. WT1high before SCT was found to be an independent prognostic factor for inferior overall survival (OS), disease-free survival (DFS), and higher cumulative incidence of relapse (CIR). There were 201 patients with WT1 low expression based upon pretransplant analysis. There was no significant difference in OS, DFS, CIR, and nonrelapse mortality between MAC and RIC patients. To conclude, post-transplant survival or relapse was not different by conditioning intensity in AML CR1 patients whose WT1 level was below 250 copies per 104ABL at transplantation.

Abstract
BACKGROUND The NIH protocol for non-myeloablative (NMA) conditioning allogeneic stem cell transplantation (alloSCT) with alemtuzumab and low-dose total body irradiation corrected the abnormal sickle cell disease (SCD) phenotype without the risk of graft-versus-host disease. However, alloSCT using NMA conditioning had been rarely applied to β-thalassemia major (β-TM) patients. METHODS To avoid prolonged immunosuppression, we developed a two-stage strategy. Mixed donor chimerism was initially achieved using the protocol developed by the NIH protocol. Thereafter, we facilitated donor chimerism using the optional reinforced stem cell (SC) infusion in cases requiring protracted immunosuppression or experiencing impending graft failure. RESULTS In this study, β-TM (n = 9) and SCD (n = 4) patients were equally effectively treated with eradicating the abnormal hemoglobin phenotype. Five patients, including four β-TM, achieved stable mixed chimerism without receiving optional reinforced SC infusion. All patients that received optional reinforced infusion achieved complete (n = 4) or mixed chimerism (n = 1). The overall survival rate and event-free survival at 4 years were 91.7% (95% CI; 53.9-98.8) in both groups, with a thalassemia-free survival rate in β-TM patients of 87.5% (95% CI; 38.7-98.1). CONCLUSION This study is the first to report successful NMA conditioning alloSCT to achieve stable mixed chimerism correcting the abnormal hemoglobin phenotype in adult β-TM patients.

Abstract
In 27% of diffuse large B cell lymphoma (DLBCL) cases, bone marrow (BM), assessed by BM biopsy, is involved. BM involvement, an extranodal site involvement, affects the International Prognostic Index (IPI) score adversely. However, chromosomal abnormalities are neither included as a prognostic factor nor are they considered in the IPI risk classification category. We retrospectively analyzed 600 DLBCL patients at diagnosis for BM involvement (by both BM biopsy immunohistochemistry [BMI] with karyotyping and 18-fluorodeoxyglucose-positron emission tomography [FDG-PET] high uptake [BMP]). The BM-involved DLBCL patients identified by both BMI and BMP showed significantly inferior survival outcomes. Chromosomal abnormalities, especially complex karyotype (CK) of the involved BM, are related to much worse survival outcomes due to the inadequate treatment response including frontline auto-hematopoietic stem cell transplantation (HSCT). Therefore, CK population should either be considered for more aggressive treatment modalities, such as frontline allo-HSCT, or those further clinical trials are explored for alternative or novel treatment approaches. Furthermore, if the FDG-PET shows high possibility of marrow involvement, bilateral BM biopsy with cytogenetic evaluation should be incorporated into the routine workup for newly diagnosed DLBCL patients. This is to look for other markers of poor-risk factors, such as CK or further genetic mutations.

Abstract
OBJECTIVE We investigated the role of anti-thymocyte globulin (ATG; Thymoglobulin) in matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT) after reduced intensity conditioning (RIC) in myelodysplastic syndrome (MDS). METHODS Forty-seven patients with 10 mg/kg ATG (ATG group; median age 53 years) and 33 without ATG (no-ATG group; median age 43, P < .0001) were compared. RESULTS Median time to engraftment was similar. Two-year cumulative incidence of moderate-to-severe chronic graft-versus-host disease (GVHD) was significantly lower in the ATG group (15% vs 55%, P < .0001), while that of acute GVHD was similar compared with the no-ATG group. After a median follow-up of 60 months (range, 14-184), the 3-year cumulative incidences of non-relapse mortality and relapse were 9% and 21% for ATG group and 15% and 19% for no-ATG group (P = .408 and P = .717), respectively, leading to a significantly better 3-year GVHD-free and relapse-free survival (GRFS) in the ATG group (55% vs 19%, P = .006): The 3-year overall and disease-free survival were similar. Infectious complication occurred with similar frequencies in both groups. CONCLUSION These findings suggest that ATG can be safely used to decrease moderate-to-severe chronic GVHD with improved GRFS for patients with MDS receiving MSD-HSCT in RIC setting.

Abstract
Background and Objectives Cells of innate immunity normally recover in the first weeks to months after allogenenic hematopoietic stem cell transplantation (allo-HSCT). Their relevance in terms of graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect is largely unknown. The predictive role of early recovery in the immune cells on acute GVHD and GVL effect after allo-HSCT was investigated in patients with acute leukemia who achieved the first complete remission. Methods Peripheral blood samples were taken at the median of 14 days (range, 12~29 days) after allo-HSCT. A cohort including 119 samples and characteristics of patients were analyzed. Immune cell populations were identified by flow cytometry. Results The median age was 49.0 years (range, 21~69) at transplantation. Univariate analysis showed that age less than 40 years old, lower frequencies of CD8+ T cells, invariant natural killer T (iNKT) cells, monocytic myeloid derived suppressor cells (M-MDSCs) and higher frequency of immature MDSCs were associated with occurrence of grade III–IV acute GVHD. Multivariate analyses showed that iNKT cells (hazard ratio (HR), 0.453, 95% CI, 0.091~0.844, p=0.024) and M-MDSCs (HR, 0.271, 95% CI, 0.078~0.937, p=0.039) were independent factors. Combination of higher frequencies of both cell subsets was associated with lower incidence of grade III–IV acute GVHD, whereas patients with lower frequency of iNKT cells and higher frequency of M-MDSCs showed significant higher probability of relapse. Conclusions iNKT cells and M-MDSCs could be relevant cell biomarkers for predicting acute GVHD and/or relapse in acute leukemia patients treated with allo-HSCT.

Abstract
OBJECTIVES We intended to identify the predictive abilities of recently published transplant-specific prognostic scoring systems in patients with myelodysplastic syndrome (MDS) receiving haploidentical transplantation. METHODS The outcomes of 73 patients with MDS receiving haploidentical transplantation were analyzed, according to the MTPSS, the TRI, and the CIBMTR scoring systems. RESULTS The median age of patients at transplantation was 50 (range, 19-69) years. The IPSS-R cytogenetic risks of very good/good, intermediate, and poor/very poor were, respectively, observed in 35 (48.0%), 25 (34.2%), and 13 (17.8%) patients, including 4 (5.5%) with a monosomal karyotype. Pretransplant treatment failure and high (≥3) HCT-CI were observed in 30 (41.1%) and 35 (48.0%) patients, respectively. With survivor's median follow-up of 42.3 months, the overall survival rate at 4 years of all patients was 65.5% (95% CI, 52.4-75.9). The MTPSS (100%, 77.3%, 62.5%, and 42.0% at 4 years; P = .02) and the TRI (100%, 79.9%, 76.0%, and 17.1% at 4 years; P < .01) differentiate proportionally overall survival rates according to their 4 risk groups, whereas the CIBMTR scoring system did not (P = .17). CONCLUSIONS Our results suggest the potential ability of the MPTSS and the TRI as prognostic tools for patients with MDS receiving haploidentical transplantation.

Abstract
To overcome unsatisfactory results of classical low-dose cytarabine (LDAC) of cytarabine ≤20 mg twice daily (BID) subcutaneously for 10 days for patients with elderly acute myeloid leukemia (eAML), we evaluated a modified LDAC (mLDAC) of cytarabine 20 mg/m2 BID subcutaneously plus etoposide 50 mg BID orally for 14 days. To determine its feasibility, we compared outcomes of 77 and 42 eAML patients who received, respectively, mLDAC and decitabine (DAC; 20 mg/m2 intravenously daily for 5 days), which has shown better outcomes compared to those of classical LDAC. Most of baseline characteristics of two groups were well balanced. The mLDAC group had a higher complete response (CR) rate compared to the DAC group (46.8% vs. 19.0%, P < 0.01). Unlike the classical LDAC, mLDAC induced CR in patients with adverse cytogenetics, with its rate similar to that of the DAC group (33.3% vs. 20.0%; P = 0.58). Meanwhile, mucositis, neutropenic fever and invasive aspergillosis were more frequently observed in the mLDAC group, with no difference in early mortality between two groups (P > 0.05). The median overall survival rates of the mLDAC and DAC groups were comparable (8.7 vs 8.3 months, respectively, P = 0.35), presumably because the advantage of higher CR rate in the mLDAC group was offset by beneficial effects of marrow response, which is observed dominantly in the DAC group. Our results suggested that the outcomes of classical LDAC could be improved by modest modifications, to be comparable to those of DAC.

Abstract
Hypomethylating treatment (HMT) has been suggested as a feasible bridge to hematopoietic stem cell transplantation (HSCT), but controversies exist around influences of HMT response on transplant outcomes. To assess the safety and influences of pre-transplant HMT focusing on debulking effects and transplant outcomes, we retrospectively analyzed consecutive HSCT-eligible patients who received HMT for higher-risk MDS with excess blasts. Of all 98 patients, 11 patients failed to proceed to HSCT and HMT-related mortality occurred in 8 patients. When excluding 9 patients who refused HSCT, 87% of scheduled HSCT (77 of 89) was performed after a median of 3 cycles (range, 1-8) of HMT. The 4-year overall survival after HMT (n = 98) and HSCT (n = 77) was 44.0% and 53.6%, respectively. Transplant outcomes were significantly different by the final response at HSCT; marrow response group (complete remission, marrow complete remission with or without hematologic improvement) showed significantly better 4-year disease-free survival compared to no marrow response group (n = 36, 87.3% vs. n = 41, 10.7%, P < 0.001). This difference between the groups was also evident in overall survival (90.9% vs. 8.6%, P < 0.001) and cumulative incidences of relapse (6.5% vs. 45.4%, P < 0.001) and treatment-related mortality (6.2% vs. 43.9%, P < 0.001). These observations indicate that pre-transplant HMT is a feasible bridging treatment in patients with excess blasts regarding high success rate of proceeding to transplantation and good survival rate. Marrow response at HSCT regardless of concomitant hematological improvement is an independent predictor of better survival, suggesting that immediate HSCT rather than continuing HMT should be performed once marrow response is achieved.

Abstract
Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders characterized by the proliferation of one or more myeloid lineages. The current study demonstrates that three driver mutations were detected in 82.6% of 407 MPNs with a mutation distribution of JAK2 in 275 (67.6%), CALR in 55 (13.5%) and MPL in 6 (1.5%). The mutations were mutually exclusive in principle except in one patient with both CALR and MPL mutations. The driver mutation directed the pathologic features of MPNs, including lineage hyperplasia, laboratory findings and clinical presentation. JAK2-mutated MPN showed erythroid, granulocytic and/or megakaryocytic hyperplasia whereas CALR- and MPL-mutated MPNs displayed granulocytic and/or megakaryocytic hyperplasia. The lineage hyperplasia was closely associated with a higher mutant allele burden and peripheral cytosis. These findings corroborated that the lineage hyperplasia consisted of clonal proliferation of each hematopoietic lineage acquiring driver mutations. Our study has also demonstrated that bone marrow (BM) fibrosis was associated with disease progression. Patients with overt fibrosis (grade ⩾2) presented an increased mutant allele burden (P<0.001), an increase in chromosomal abnormalities (P<0.001) and a poor prognosis (P<0.001). Moreover, among patients with overt fibrosis, all patients with wild-type JAK2/CALR/MPL (triple-negative) showed genomic alterations by genome-wide microarray study and revealed the poorest overall survival, followed by JAK2-mutated MPNs. The genetic–pathologic characteristics provided the information for understanding disease pathogenesis and the progression of MPNs. The prognostic significance of the driver mutation and BM fibrosis suggests the necessity of a prospective therapeutic strategy to improve the clinical outcome.

Abstract
Severe graft-versus-host disease (GVHD) is an often lethal complication of allogeneic hematopoietic stem cell transplantation (HSCT). The safety of clinical-grade mesenchymal stem cells (MSCs) has been validated, but mixed results have been obtained due to heterogeneity of the MSCs. In this phase I study, the safety of bone marrow-derived homogeneous clonal MSCs (cMSCs) isolated by a new subfractionation culturing method was evaluated. cMSCs were produced in a GMP facility and intravenously administered to patients who had refractory GVHD to standard treatment resulting after allogeneic HSCT for hematologic malignancies. After administration of a single dose (1×106 cells/kg), 11 patients were evaluated for cMSC treatment safety and efficacy. During the trial, nine patients had 85 total adverse events and the rate of serious adverse events was 27.3% (3/11 patients). The only one adverse drug reaction related to cMSC administration was grade 2 myalgia in one patient. Treatment response was observed in four patients: one with acute GVHD (partial response) and three with chronic GVHD. The other chronic patients maintained stable disease during the observation period. This study demonstrates single cMSC infusion to have an acceptable safety profile and promising efficacy, suggesting that we can proceed with the next stage of the clinical trial.

Abstract
Background This report focuses on the adaptive phase I trial design aimed to find the clinically applicable dose for decitabine maintenance treatment after allogeneic hematopoietic stem cell transplantation in patients with higher-risk myelodysplastic syndrome and secondary acute myeloid leukemia. Methods The first cohort (three patients) was given the same initial daily dose of decitabine (5 mg/m2/day, five consecutive days with 4-week intervals). In all cohorts, the doses for Cycles 2 to 4 were individualized using pharmacokinetic-pharmacodynamic modeling and simulations. The goal of dose individualization was to determine the maximum dose for each patient at which the occurrence of grade 4 (CTC-AE) toxicities for both platelet and neutrophil counts could be avoided. The initial doses for the following cohorts were also estimated with the data from the previous cohorts in the same manner. Results In all but one patient (14 out of 15), neutrophil count was the dose-limiting factor throughout the cycles. In cycles where doses were individualized, the median neutrophil nadir observed was 1100/mm3 (grade 2) and grade 4 toxicity occurred in 5.1 % of all cycles (while it occurred in 36.8 % where doses were not individualized). The initial doses estimated for cohorts 2 to 5 were 4, 5, 5.5, and 5 mg/m2/day, respectively. The median maintenance dose was 7 mg/m2/day. Conclusions We determined the acceptable starting dose and individualized the maintenance dose for each patient, while minimizing the toxicity using the adaptive approach. Currently, 5 mg/m2/day is considered to be the most appropriate starting dose for the regimen studied. Trial registration Clinicaltrials.gov NCT01277484

Abstract
Background The expression of the SOCS genes in cytomegalovirus (CMV) viremia after hematopoietic stem cell transplantation (HSCT) remains largely unexplored. Methods Using quantitative RT-PCR of mononuclear cells, we conducted pairwise comparison of SOCS1 and SOCS3 expression levels among a healthy donor group (N=55), a pre-HSCT group (N=17), and the recipient subgroup (N=107), which were divided according to the occurrence of CMV viremia and acute graft-versus-host disease (aGVHD). Results Compared to that in the healthy donor group, SOCS1 expression was higher in the CMV+ subgroup, especially in the CMV+GVHD- group, but decreased in the other subgroups. When compared to the expression in the pre-HSCT group, SOCS1 expression was significantly higher in the CMV+ subgroup, especially in the CMV+GVHD+ subgroup. Meanwhile, compared to that in the healthy donor group, SOCS3 expression was significantly lower in all other groups. The CMV-GVHD- subgroup showed significantly lower SOCS3 expression compared to the CMV+ subgroup, the CMV+GVHD+ subgroup, and the CMV+GVHD- subgroup. Conclusion We report differential expression of SOCS genes according to CMV viremia with acute GVHD occurrence after HSCT, suggesting that regulation of SOCS expression is associated with CMV viremia.

Abstract
Even with the recent optimization of haploidentical stem cell transplantation (SCT), its role for patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia evolving from MDS (sAML) should be validated. We analyzed the outcomes of consecutive 60 patients with MDS or sAML who received T cell-replete haploidentical SCT after reduced-intensity conditioning with fludarabine, busulfan, and rabbit antithymocyte globuline ± 800 cGy total body irradiation. Patients achieved a rapid neutrophil engraftment after a median of 12 days (range, 8 to 23) and an early immune reconstitution without high incidences of acute graft-versus-host disease (GVHD) II to IV and chronic GVHD (36.7% and 48.3%, respectively). After a median follow-up of 4 years, incidence of relapse and nonrelapse mortality and rate of overall survival and disease-free survival was 34.8%, 23.3%, 46.8%, and 41.9%, respectively. In multivariate analysis, the disease status at peak was a significant predictor for relapse (lower-risk MDS versus higher-risk MDS or sAML; hazard ratio [HR], 5.69; 95% confidence interval [CI], 1.45 to 22.29; P = .013) and disease-free survival (HR, 4.44; 95% CI, 1.14 to 17.34; P = .032). Chronic GVHD was an additional significant predictor for relapse (no versus yes; HR, 2.87; 95% CI, 1.03 to 7.51; P = .043). Our T cell-replete haploidentical SCT may be a feasible option for patients with MDS and sAML without conventional donors.

Abstract
We analyzed the outcome of stem cell transplantation (SCT) for 59 acute myeloid leukemia (AML) patients with t(8;21). The 5-year overall and disease-free survival (OS and DFS) were 70.2 and 68.4%, respectively. The 5-year cumulative incidence of relapse (CIR) and nonrelapse mortality were 16.9 and 13.6%, respectively. OS and DFS in the reduced-intensity conditioning (RIC)-SCT group (70.4%) were not different from in the autologous SCT (ASCT) group (72.4 and 69.0%, respectively). Age was a factor affecting OS (p = 0.007) and DFS (p = 0.008) in the ASCT group, but not in the RIC-SCT group. In the ASCT group, lack of the X chromosome (-X) and an age of >50 years were associated with inferior survival; however, these differences disappeared in the RIC-SCT group. CIR was significantly higher in patients with -X than in those without -X only in the ASCT group (p = 0.038), i.e. not in the RIC-SCT group. ASCT and RIC-SCT are equally effective for the intensification of postremission treatment of AML patients with t(8;21). The subgroups with advanced age or -X should be preferentially considered for RIC-SCT, rather than ASCT. Further investigations with randomized prospective trials of a sizeable study population are warranted.

Abstract
Eighty adult patients with acute myeloid leukemia (AML) received peripheral blood T cell-replete HLA haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Disease status at transplantation was either first or second complete remission (CR, n = 69) or relapse/refractory (n = 11). Identical transplant-related procedures with conditioning regimen consisting of fractionated 800 cGy total body irradiation (TBI), fludarabine (30 mg/m(2)/day for 5 days), busulfan (3.2 mg/kg/day for 2 days), and antithymocyte globulin (1.25 mg/kg/day on days -4 to -1) and graft-versus-host disease (GVHD) prophylaxis with tacrolimus and methotrexate were used in all patients. Recovery of neutrophil (median, 11 days) and platelet (median, 10 days) counts was achieved in all patients with full donor chimerism (≥ 99%), and no delayed engraftment failure was observed. The cumulative incidence of grades III to IV acute GVHD and moderate to severe chronic GVHD was 11.2% and 26.3%, respectively. A donor CD8(+) and CD4(+) T cell dose above the median value was significantly associated with the incidences of grades II to IV acute GHVD and moderate to severe chronic GVHD, respectively. After a median follow-up of 28 months for survivors, the 2-year cumulative incidences of relapse (n = 20) and nonrelapse mortality (n = 10) were 26.6% and 12.2%, respectively. Although all but 1 patient in relapse/refractory status died, the 2-year overall and progression-free survival of patients in first CR was 82.5% and 75.1%, respectively. We suggest the strategy of fractionated 800 cGy TBI-based conditioning with unmanipulated peripheral blood stem cell grafts seems feasible with favorable outcomes for adult patients with AML undergoing haplo-HSCT in CR.

Abstract
BACKGROUND After hematopoietic stem cell transplantation (HSCT), early detection of engraftment would be of critical value for clinicians. The aim of this study was to identify faster parameters for engraftment. METHODS We evaluated blood cell parameters including complete blood count (CBC), differential counts, and various reticulocyte parameters in 115 patients who received HSCT (allogeneic, n = 93; autologous, n = 22) in the purpose of identifying possible improved laboratory guidelines for engraftment prediction. RESULTS AND CONCLUSION Days to white blood cell (WBC) count over 100 cells/μl with more than two-fold increase from nadir after transplantation (proposed new WBC guideline) preceded absolute neutrophil count (ANC) >500 cells/μl by 1.7 days. Among erythroid parameters, the earliest marker for erythroid engraftment was high light scattering reticulocytes (HLR) >0.1 (proposed new red blood cell guideline), which preceded reticulocyte counts (RET) >1% and immature reticulocyte fraction >0.5 by 3.9 and 1.6 days, respectively. Among the clinical parameters compared, those with statistically significant influence on myeloid engraftment were donor type (P = 0.009) and conditioning intensity (P = 0.009). As for erythroid recovery, ABO incompatibility was the only significant factor. In conclusion, the new guidelines may ensure engraftment several days earlier than the conventional parameters, which may help clinicians for decision-making on rescue therapy earlier.

Abstract
BACKGROUND In unrelated donor allogeneic stem cell transplantation (URD-SCT), most studies reported that peripheral blood stem cells (PBSC) resulted in higher incidence of acute and/or chronic graft-versus-host disease (GVHD) without survival benefits compared with bone marrow (BM). To overcome these shortcomings of PBSC, we have used a risk-adapted GVHD prophylaxis for patients that received HLA-matched URD-SCT, which was adding low-dose rabbit antithymocyte globulin (Thymoglobulin(®) , 1.25 mg/kg for 2 d) to conditioning in the transplants with PBSC and not BM. METHODS To determine whether this strategy is effective, we analyzed 115 adult patients with acute myeloid leukemia who received HLA-matched URD-SCT with PBSC (n = 70) or BM (n = 45) using our risk-adapted GVHD prophylaxis strategy. RESULTS The PBSC group showed faster neutrophil (11 d vs. 13 d; P < 0.01) and platelet (12 d vs. 18 d; P < 0.01) engraftment compared with the BM group. No difference was observed in the incidence of acute GVHD grade II-IV at 100 d (54.3% vs. 64.4%; P = 0.38) and chronic GVHD at 4 yr (65.1% vs. 60.0%; P = 0.83). Other outcomes including the incidence of relapse (30.8% vs. 31.2%; P = 0.53), non-relapse mortality (13.5% vs. 6.9%; P = 0.24), disease-free survival (55.7% vs. 61.9%; P = 0.68), and overall survival (62.2% vs. 63.2%; P = 0.96) at 4 yr were not significantly different. CONCLUSION Our risk-adapted GVHD prophylaxis strategy resulted in similar transplant outcomes including comparable incidence of GVHD between the PBSC and BM groups in HLA-matched URD-SCT.

Abstract
BACKGROUND Numerous studies tried to find new markers that after hematopoietic stem cell transplantation predict engraftment earlier than the conventional marker, absolute neutrophil count (ANC >500/µL). Early engraftment prediction can be achieved by a marker that reflects the release of neutrophils and monocytes into the leukopenic peripheral blood. METHODS We analyzed blood cell parameters, including cell population data such as volume, conductivity, and light scatter in 77 patients who underwent HSCT (allogeneic, n=63; autologous, n=11) to detect possible markers. RESULTS We identified 2 early engraftment markers of neutrophils (NEUTRO) and monocytes (MONO); a pair of mean-volume-neutrophils (MNV) and mean-conductivity-neutrophils (MNC) for NEUTRO; and a pair of mean-volume-monocytes (MMV) and mean-conductivity-monocytes (MMC) for MONO. The new markers showed distinct patterns for early engraftment wherein 1) on the engraftment day, MNV peaked as MNC notched simultaneously for every case, and 2) MMV peaked as MMC notched simultaneously in most cases. Engraftment was predicted 3.8±2.7 days earlier than by ANC in 74 successful engraftment cases by using NEUTRO and/or MONO: 1) 72 cases (97.3%), in which NEUTRO and/or MONO predicted earlier engraftment than ANC, 2) 1 case, in which the 3 markers predicted engraftment on the same day, and 3) 1 case, in which NEUTRO predicted engraftment on the same day as ANC and MONO failed to predict engraftment. CONCLUSIONS By analyzing the data from daily complete blood counts, engraftment can be predicted approximately 4 days earlier than ANC >500/µL using NEUTRO as a base marker and MONO as a supplementary marker.

Abstract
The aim of this study was to estimate the prognostic factors for the outcomes of chronic myeloid leukemia (CML) patients receiving allogeneic stem cell transplantation (SCT) in chronic phase (CP) in the era of tyrosine kinase inhibitors (TKIs). Ninety-seven patients who underwent allogeneic SCT in CP were analyzed. Forty-seven were TKI-naïve at the time of transplant, and 50 received TKI(s) treatment before transplantation. After a median follow-up of 115.8 months, the 4-year overall survival and event-free survival were 80.4 and 58.8%, respectively. Multivariate analysis showed that there were no differences in survival outcomes based on prior TKI therapy. Older age was a prognostic factor for higher treatment-related mortality (TRM), and the type of graft source and younger age were associated with relapse, but prior TKI therapy and disease status at the time of transplant were not associated with either TRM or relapse. Additionally, a major molecular response at 1 month and an MR(4.5) at 3 months were important predictors of favorable long-term outcomes. This study demonstrates the prognostic factors for the outcomes of allogeneic SCT in CP CML and shows that survival outcomes were not affected by the administration of long-term multi-TKI treatment prior to transplantation.

Abstract
In Asia, the incidence of chronic lymphocytic leukaemia (CLL) is lower than in Western countries. Only a few studies of CLL have been conducted in Korea, and no long-term clinical outcome data are available. We assessed the frequency of common chromosomal aberrations in Korean CLL patients using interphase fluorescence in situ hybridization (FISH) and investigated their relationship to clinical outcomes. Between 2000 and 2011, conventional cytogenetic studies were performed in 58 patients, and FISH results were available in 48 patients. We used six DNA probes for the detection of del(13q14), trisomy 12, del(11q22), del(17p13), IGH rearrangement and del(6q23). Chromosomal aberrations were identified in 15 of 58 patients (26%) with conventional cytogenetic studies and in 25 of 48 patients (52%) with interphase FISH, including six patients with complex karyotypes. In contrast with the results of Western studies, trisomy 12 was the most common aberration, followed by IGH rearrangement, del(13q14), del(11q22) and del(17p13). Deletion of 6q23 was not observed, and isolated del(13q14) was less frequent than in Western studies. Compared with the other types of chromosomal aberrations, patients with del(11q22) and del(17p13) were more likely to be Rai stage 3-4 and Binet stage C, resulting in poor responses to chemotherapy and worse outcomes. In contrast, patient with trisomy 12 and isolated del(13q14) showed better responses and superior survival outcomes. The incidence of CLL is lower in Korea than in Western countries, and the frequency of chromosomal aberrations differs, perhaps reflecting differences in the pathogenic mechanism between ethnicities. Large prospective studies are needed to further assess the prognostic value of these results in Korean CLL patients.

Abstract
Background Novel agents (NAs) such as thalidomide and bortezomib have been administered in combination with autologous stem-cell transplantation (ASCT) to effectively treat multiple myeloma (MM). However, whether NAs perform better as induction treatments prior to transplantation, or as post-transplant maintenance therapies remains unclear. Methods We retrospectively analyzed 106 consecutive patients with MM who underwent ASCT within 1 year of diagnosis as first-line therapy. Results Eighty-seven (82.1%) patients received NAs before ASCT, whereas 68 (64.2%) received NAs after ASCT. NAs were administered to each patient as follows: before ASCT alone (N=29, 27.4%), after ASCT alone (N=10, 9.4%) or both before and after ASCT (N=58, 54.7%). High-quality rates before and after ASCT were significantly higher for patients who received NAs as induction treatment compared to those who did not receive pre-transplant NAs. At a median follow-up of 37.9 months, the 3-year progression-free survival (PFS) and overall survival (OS) rates were 42.8% and 70.2%, respectively. The PFS and OS were significantly higher in patients with NAs as post-transplant maintenance treatment (P=0.03 and P=0.04, respectively), but not in those with NAs as pre-transplant induction treatment. The PFS of patients with NAs before and after ASCT was higher than that of the patients with NAs as induction therapy alone (P=0.05). Age, serum β2-microglobulin level, complete response after ASCT, and NA use post-ASCT independently predicted survival outcomes. Conclusion These findings suggest that integration of NAs post-ASCT could benefit patients with MM undergoing ASCT. Induction therapy using NAs also improves high-quality response rates before and after ASCT.

Abstract
The role of reduced-intensity conditioning (RIC) in adult acute lymphoblastic leukemia (ALL) remains unclear because of the small sample size, short follow-up duration, various regimens for conditioning and graft-versus-host disease (GVHD) prophylaxis, and the heterogeneity of selection criteria for transplantation. We compared long-term outcomes of 60 consecutive RIC transplants (fludarabine plus melphalan) with 120 myeloablative conditioning (MAC) transplants (total body irradiation plus cyclophosphamide) for adult high-risk ALL in first or second complete remission. All transplants received a uniform strategy of pretransplant chemotherapy and GVHD prophylaxis. Compared to MAC transplants, RIC transplants had older age (46 years vs. 33 years, P < 0.001) and higher proportions of transplantation using peripheral blood (93.3% vs. 13.3%; P < 0.001) but otherwise showed similar characteristics. After a median follow-up of 67 months, RIC transplants showed comparable nonrelapse mortality (21.2% vs. 24.3%) and disease-free survival (50.8% vs. 54.9%) to MAC transplants, although relapse risk was higher (34.2% vs. 26.4%; HR, 2.07; P = 0.019) in multivariate analysis. Other independent factors associated with better outcomes were the presence of chronic GVHD and transplantation in first complete remission. Interestingly, the negative impact of RIC on relapse risk was seen only for Philadelphia-positive ALL transplants (32.7% vs. 19.6%; HR, 3.46; P = 0.020), while no difference was found between RIC and MAC for Philadelphia-negative ALL transplants (35.0% vs. 32.1%; HR, 1.39; P = 0.429). RIC can be considered as a reasonable choice for providing a sufficient long-term graft-versus-leukemia effect for adult high-risk ALL patients ineligible for MAC.

Abstract
Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie's syndrome, is a rare clinical syndrome of massive large bowel dilatation without mechanical obstruction, which may cause significant morbidity and mortality. Treatment focuses on decompressing a severely dilated colon. The proposed theory that this severe ileus results from an imbalance in the autonomous regulation of colonic movement supports the rationale for using neostigmine, a reversible acetylcholinesterase inhibitor, in patients who failed conservative care. Although gastrointestinal complications are frequent following allogeneic stem cell transplantation (SCT), the incidence of ACPO in a transplant setting is unknown and, if not vigilant, this adynamic ileus can be underestimated. We describe the case of a patient with myelodysplastic syndrome undergoing non-myeloablative allogeneic SCT from a partially human leukocyte antigen-mismatched sibling donor, and whose clinical course was complicated by ACPO in the early post-engraftment period. The ileus was not associated with gut graft-versus-host disease or infectious colitis. After 3 days of conservative care, intravenous neostigmine (2 mg/day) was administered for 3 consecutive days. Symptoms and radiologic findings began to improve 72 hours after the initial injection of neostigmine, and complete response without any associated complications was achieved within a week. Thus, neostigmine can be a safe medical therapy with successful outcome for patients who develop ACPO following allogeneic SCT.

Abstract
No consecutive analysis of BAALC and WT1 expressions associated with core-binding factor AML (CBF-AML) from diagnosis to hematopoietic stem cell transplantation (HSCT) has yet been reported. We investigated BAALC and WT1 expressions using a method of real-time quantitative polymerase chain reaction (RQ-PCR) at diagnosis, after induction chemotherapy, at pre-HSCT, and at post-HSCT period in 45 consecutive patients [t(8,21) (n = 28), inv(16) (n = 17)], who received HSCT as a post-remission treatment. BAALC and WT1 RQ-PCR decrement ratio (DR) was also calculated at post-induction chemotherapy, at pre-HSCT, and at post-HSCT compared with the diagnostic level. Higher BAALC expression at diagnosis showed significantly inferior OS (P = 0.031), EFS (P = 0.011), and higher CIR (P = 0.002) rates. At post-HSCT, both higher BAALC and WT1 expressions showed significantly inferior OS (P = 0.005, 0.016), EFS (P = 0.002, 0.006), and higher CIR (P = 0.001, 0.003) rates. A subgroup of t(8;21) showing higher BAALC and WT1 expressions at post-HSCT were also associated with inferior OS (P = 0.018, 0.015) and higher CIR rates (P = 0.019, 0.011). While BAALC DR showed no significant results on outcomes, WT1 DR more than 2-log at post-HSCT showed significantly lower CIR rate (P = 0.028). This study showed that higher post-HSCT BAALC and WT1 expressions in patients with CBF-AML may be good markers of minimal residual disease for the prediction of survival and relapse after HSCT.

Abstract
Using real-time quantitative PCR, we monitored Wilms tumor gene 1 (WT1) expression from diagnosis to hematopoietic stem cell transplantation (HSCT) in adult patients with cytogenetically normal acute myelogenous leukemia (CN-AML) and FLT3-ITD and NPM1 mutations. The values at diagnosis were evaluated in 104 patients. Data collected after induction chemotherapy were available for all patients, but only 68 patients were treated with HSCT. Significant WT1 expression cut-offs were determined by receiver operation characteristic curve analysis, and rates of overall survival (OS) and disease-free survival (DFS) were estimated. WT1 decrement ratios (DR) at postinduction chemotherapy and at pre- and post-HSCT compared with the diagnostic level were calculated. Higher WT1 expression at diagnosis, postinduction chemotherapy, and pre-HSCT showed inferior OS (P = .015, <.001, and .002) and DFS (P = .006, <.001, and .003). The cut-offs were determined at the median for diagnostic WT1 expression and at the 25% level from the top for other time points excluding post-HSCT. The WT1 DR ≥ 1-log after induction chemotherapy showed superior OS and DFS (P = .009 and .002) and WT1 DR ≥ 1-log preceding HSCT also showed superior OS and DFS (P = .009 and .003). Results of WT1 DR were consistently applicable in each subgroup with higher (≥ 1.0) and lower (<1.0) WT1 expression at diagnosis and also in NPM1-wild-type/FLT3-ITD-negative CN-AML. The WT1 DR therefore predicted survival outcomes after HSCT more accurately than did the diagnostic WT1 expression. WT1 expression may serve as a reliable marker for residual disease and WT1 DR as a prognostic indicator, particularly in NPM1-wild-type/FLT3-ITD-negative CN-AML. These measures may be applied throughout the course of treatment and even after HSCT.

Abstract
Background Suppressor of cytokine signaling genes (SOCS) are regarded as pivotal negative feedback regulators of cytokine signals, including the interferon-gamma (IFN-γ), granulocyte-colony stimulating factor, and interleukin families, released by T cells. A detailed understanding of the involvement of SOCS genes in graft-versus-host disease (GVHD) is critical to effectively manage GVHD, yet their expression patterns among recipients remain largely unexplored. Methods Expression levels of SOCS1 and SOCS3 were determined by real-time quantitative reverse transcription PCR (qRT-PCR) in patients with acute GVHD (aGVHD) and chronic GVHD (cGVHD), in a severity-dependent manner, after allogeneic hematopoietic stem cell transplantation (HSCT). A total of 71 recipients with AML (N=40), ALL (N=12), myelodysplastic syndromes (MDS; N=10), chronic myelogenous leukemia (CML; N=2), severe aplastic anemia (SAA; N=5), or others (N=2), who received allogeneic HSCT from human leukocyte antigen-identical siblings or unrelated donors between 2009 and 2011, were included in the present study. Results Overall, the expression levels of SOCS1 decreased in recipients with grade II to IV aGVHD and cGVHD when compared to normal donors and non-GVHD recipients. Interestingly, the expressions of SOCS1 decreased significantly more in cGVHD than in aGVHD recipients (P=0.0091). In contrast, SOCS3 expressions were similarly reduced in all the recipients. Conclusion This is the first study to show that SOCS1 and SOCS3 are differentially expressed in recipients following allogeneic HSCT, suggesting a prognostic correlation between SOCS genes and the development of GVHD. This result provides a new platform to study GVHD immunobiology and potential diagnostic and therapeutic targets for GVHD.

Abstract
Tacrolimus is a widely used immunosuppressive agent for the prophylaxis of graft-versus-host disease in allogeneic hematopoietic stem cell transplantation (HSCT). Since tacrolimus is primarily metabolized by the liver, hepatic dysfunction may affect its metabolism. Hepatic veno-occlusive disease (VOD) is an early complication of HSCT that results in hepatic dysfunction, suggesting that VOD may affect tacrolimus metabolism. We report a case of hepatic VOD accompanied by a sustained high blood trough level of tacrolimus despite its discontinuation. The findings of this case suggest that the elimination of tacrolimus can be markedly delayed in patients with hepatic VOD, and that the clinician should carefully modulate the drug dosage for these patients.

Abstract
OBJECTIVES For patients with acute myeloid leukemia in first complete remission (AML CR1) lacking HLA-matched sibling donors (MSD), 8/8-matched unrelated donors (URD) are mostly used in cases with poor-risk features. For AML CR1 with intermediate cytogenetics, however, the benefit of 8/8-matched URD should be compared with non-allogeneic therapies as well as MSD. METHODS To address this issue, we assessed the transplantation outcomes of 8/8-matched URD (n = 54) compared with MSD (n = 145) or autologous transplantation (n = 89) for AML CR1 with intermediate cytogenetics. RESULTS In multivariate analyses, 8/8-matched URD had comparable 6-yr overall survival (OS, P = 0.997), disease-free survival (DFS, P = 0.951), and relapse (P = 0.672) to MSD, whereas 8/8-matched URD had a higher OS (P = 0.070) and DFS (P = 0.035) with lower relapse (P = 0.009) than autologous transplantation. No difference in non-relapse mortality was observed according to donor type. Notably, these equivalent or superior outcomes of 8/8-matched URD compared with MSD or autologous transplantation, respectively, were particularly evident in patients without poor-risk features (n = 200), such as older age, hyperleukocytosis at diagnosis, and myelodysplasia-related changes, who are not usual candidates for URD transplantation. CONCLUSIONS These results indicate that 8/8-matched URD are feasible next option in AML CR1 with intermediate cytogenetics, when lacking MSD, even in patients without poor-risk features.
