Abstract Purpose The success of allogeneic hematopoietic stem cell transplantation (HSCT) is compromised by complications such as infection, relapse, and graft-versus-host disease (GVHD). The investigation of non-HLA immunogenetics, particularly of cytokines, could identify predictors of an unfavorable outcome after allogeneic HSCT. In this study, we examined the impact of single nucleotide polymorphisms (SNPs) within the promotor region of interleukin 6 (IL6) on the development of GVHD after pediatric allogeneic HSCT. Methods In this retrospective analysis, we included 320 pediatric patients with a median age of 10 years who underwent an allogeneic HSCT and their respective donors. We used TaqMan real-time polymerase chain reaction to analyze the SNPs IL6-174 (G/C) and IL6-597 (G/A). The IL6-174 polymorphism was examined in 300 recipients and 295 donors. The IL6-597 polymorphism was analyzed in 299 recipients and 296 donors. We investigated the influence of the IL6-174 and IL6-597 polymorphisms on overall survival, event-free survival, relapse incidence, transplant-related mortality, and the occurrence of GVHD. Results GG polymorphism at position 174 of the recipient IL6 gene was associated with a higher incidence of acute GVHD (GG vs. GC/CC; P = 0.024). Patients with IL6-597 GG genotype developed acute GVHD more frequently than individuals with an A allele (GG vs. GA vs. AA; P = 0.013). IL6-174 GG homozygous recipients had a more frequent occurrence of chronic GVHD (GG vs. GC/CC; P = 0.049). We observed a significant increased risk of chronic GVHD in recipients with IL6-597 GG genotype (GG vs. GA vs. AA; P = 0.043). Polymorphisms of donors did not affect the incidence of acute GVHD and chronic GVHD. In multivariate analysis, the IL6-174 and IL6-597 SNPs were independent significant risk factors for acute GVHD (P = 0.030; P = 0.007, respectively) as well as for chronic GVHD (P = 0.045; P = 0.015, respectively). In addition, older age at time of transplantation turned out to be a significant risk factor for chronic GVHD (P = 0.003). Conclusion Our study identified the IL6-174 and IL6-597 GG genotypes of pediatric allogeneic HSCT recipients as genetic risk factors for the development of acute GVHD and chronic GVHD. After evaluations in further studies, these findings could implicate the adjustment of prophylactic measures to reduce the occurrence of acute GVHD and chronic GVHD.

Abstract Abstract 1970 Introduction: Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative treatment for many hematologic malignancies and non-malignant hematopoietic disorders, but is associated with significant morbidity and mortality with focus on acute and chronic graft-versus-host disease (GvHD). Chronic GvHD (cGvHD) occurs with increasing frequency, hampering quality of life of patients post-allogeneic HSCT and leading to increased morbidity and mortality even years after allogeneic HSCT. Diagnosis of chronic GvHD is based on clinical features and histology. Here we present the generation of cGvHD-specific proteomic pattern (cGvHD-MS14) using capillary electrophoreses and mass spectrometry to analyze urine sample collected prospectively after allogeneic HSCT. Methods: A proteomic pattern (cGvHD-MS14) was developed in order to diagnose cGvHD, to differentiate acute versus cGvHD, and to predict onset and severity of cGvHD prior to clinical diagnosis of cGVHD as a non-invasive, unbiased laboratory test for diagnosis of cGvHD. This pattern was prospectively evaluated on 329 patients (1034 urine samples) after allogeneic HSCT at MHH and 3 collaborating transplant centers. The majority of the patients had acute leukemias prior to transplantation (n=210) and were transplanted from matched unrelated or related donors (MUD n=134; MRD n=125). Reduced intensity conditioning regimens were used in about 75% of all patients and the majority (80%) received ATG (anti-thymocyte globulin) as GVHD-prophylaxis prior to transplantation and a calcineurin-inhibitor based prophylaxis afterwards. Results: Prospective and blinded evaluation revealed the correct classification of patients developing cGvHD with a sensitivity 78% and specificity of about 71% at time of diagnosis. Differentiation between late onset acute GvHD and chronic GvHD was achieved in 3 patients in this validation set. Acute GvHD prior to day 100 is not recognized by cGvHD-MS14, since aGvHD-specific peptides had been excluded during cGvHD-pattern generation. The pattern consists of 14 differentially excreted peptides, differentiating chronic GvHD from tolerant patients. Four of 14 peptides have been sequenced to date, 2 are fragments from collagen 1, 1 is from inter-alpha trypsin inhibitor heavy chain 4 and 1 is a fragment from the fibrinogen ß-chain. Conclusions: The proteomic pattern of urine proteomics enables diagnosis of cGvHD as well as differentiation of acute versus chronic GvHD. Further prospective evaluation of the cGvHD-specific pattern cGvHD-MS14 for organ specificity as well as severity prediction is currently ongoing. Taken together our results indicate that diagnosis of cGvHD is possible using CE/MS analysis of prospectively collected urine samples with high sensitivity and specificity.

Abstract Abstract 4540 Introduction The impact of HLA DRB3 and DRB4 allele mismatch after allogeneic HSCT using unrelated donors is unclear. We therefore examined retrospectively the outcome of 35 patients who received HLA-10/10 unrelated hematopoietic stem cell transplantation with a DRB3 or DRB4 mismatch between 2005 and 2011. This cohort of 35 patients was a part of a cohort of 132 consecutive patients who underwent allogeneic HSCT between 2005–2011 with a 10/10-HLA matched donor. There were 18 males (51.4%) and 17 females (48.6%) with a median age of 48 years (range, 6–64), there were 13 (37%) AML, 9 (26%) ALL, 4 (11.5%) MDS, 3 (8.5%) multiple myeloma and 6 (5.7%) other (CML, CLL, NHL). Twenty patients (57%) received a myeloablative conditioning (MAC) and 15 (43%) received a reduced intensity conditioning (RIC). At transplantation, 21 patients (60%) were in complete remission (CR), 4 patients (11.5%) in partial remission (PR) and 10 (28.5%) in relapse; 13 (37%) patients received peripheral blood stem cell (PBSC) and 22 (63%) received bone marrow (BM). Twelve (34%) patients had a mismatched DRB4 donor and 23 (66%) patients had a mismatched DRB3 donor. In the remains of 97 patients, there were 55 male (57%) and 42 female (43%), 28 (29%) patients received a MAC and 69 (71%) a RIC as regimen before allogeneic HSCT. The stem cell source was BM for 32 (34%) patients and PBSC for 65 (66%). At transplantation, 34 (35%) patients are in CR and 63 (65%) were in PR. The distribution of diagnosis was acute leukaemia and MDS for 44 (45%), CLL for 2 (2.5%) and other diagnosis (aplastic anemia, NHL, CML, MPS) for 51 patients (52.5%). Results After HSCT, 124 (94%) patients engrafted. After a median follow-up of 11.5 months (range, 0–76), the cumulative incidence of acute GvHD≥2 at 3 months was 20% (95%CI,16.5–24) and the cumulative incidence of chronic GvHD at one year was 19 % (95%CI, 15–22). In univariate analysis, the mismatch DRB3 or DRB4 had no effect on engraftment and no effect on acute GvHD (p=0.08) or chronic GvHD (p=0.63). There was no impact of DRB3 or DRB4 mismatch on relapse (p=0.33 and p=0.53, respectively) and on PFS (p=0.63 and p=0.07, respectively). We found an impact of the DRB4 mismatching (p=0.016) on overall survival. The median survival for patient without DRB3 or DRB4 mismatch was 23 months (14-NR), for patients with DRB3 mismatch 32 months (12-NR), and for DRB4 mismatched patients 5 months (3-NR). The probability of survival at 24 months, for patients without mismatch DRB3 or DRB4 is 47% (36–61), for patients with DRB3 mismatch 51% (32–82) and for DRB4 mismatched patients 19% (6–66%). (figure1). The multivariate analysis that studied age, type of disease, DRB3 or DRB4 mismatch, sexmatching, TBI, ATG, disease status at transplantation and type of conditioning and stem cell source showed a significant impact of mismatch DRB4 on survival (HR= 2.5 [95%CI, 1.2–5.5] p=0.019); there was no impact for DRB3 mismatch (HR= 1.3 (95%CI,0.5–3.9 p=0.58). We found also an impact of the DRB4 mismatch on TRM (HR= 3.5; [95%CI, 1.6 –8] p= 0.026). The incidence of TRM at 24 months for patients without DRB3 or DRB4 mismatch is 29% (24–34), for patients with DRB3 mismatch 17% (9–26%) and for DRB4 mismatched patients 50% (34–66%). (figure 2). Conclusion The HLA DRB4 matching donor is relevant for survival of patients who undergo allo-HSCT from unrelated donor in the HLA-10/10 matching settings. In view of the important impact of these loci mismatches on clinical outcome, it seems to be important to consider this matching loci in the unrelated donor selection.

Abstract Background Recent initiatives to improve patient safety and reduce healthcare costs have focused on preventing hospital readmissions. Historically, patients treated with allogeneic hematopoietic stem cell transplantation (HSCT) have high rates of hospital readmission. The purpose of this study was to identify the incidence and associated risk factors for readmissions in allogeneic HSCT patients and to evaluate the impact of readmissions on overall survival. Methods A retrospective review of patients receiving a myeloablative (MAC) or reduced intensity conditioning (RIC) HSCT at Dana Farber/Brigham and Women’s Hospital between January 1, 2005 and December 31, 2010 was performed. At our institution, RIC transplant patients are typically discharged on day +1. The 30-day readmission rate, a standard benchmark used by the Centers for Medicare & Medicaid Services, and the day 100, a traditional assessment point in transplantation, readmission rates were examined. Reasons for readmission as well as sociodemographic, disease, and HSCT-related variables were evaluated. Risk factors for readmission and the impact of readmission on overall survival were assessed by multivariate regression analysis. Results A total of 1097 HSCT patients were reviewed. In the MAC group, 130 of 495 (26.3%) patients were readmitted within 30 days of discharge and 194 (39.2%) patients were readmitted by day 100 following transplantation. 74.2% of the MAC patients had one readmission by day 100. In the RIC group, 105 of 602 (17.4%) patients were readmitted within 30 days of discharge and 185 (30.7%) patients were readmitted by day 100 following transplantation. 69% of the RIC patients had one readmission by day 100. In both groups, the most frequent reasons for readmission were infection (27.6% in MAC group, 26% in RIC group), fever without a source (19.1% in MAC group, 19% in RIC group), and graft versus host disease (17.9% in MAC group, 15.1% in RIC group). In the MAC group, a multivariate logistic regression model of the probability of being readmitted suggested that the principal risk factors for readmission by day 100 were infection during the index transplant admission (OR 1.9, p=0.0006) and Latino ethnicity (OR 4.6, p=0.013). In the RIC group, active disease at the time of HSCT (OR 2.1, p=0.0001), infection during the index admission (OR 4.8, p<0.0001), a mismatched donor (OR 2.1, p=0.030) and non-private (32.1% Medicaid, 66.4% Medicare, 1.5% other) insurance (OR 1.6, p=0.029) were significant risk factors for readmission by day 100. In a landmark analysis of patients who survived beyond the studied time points, the 5-year overall survival (OS) for those readmitted within 30 days of discharge from the index HSCT in the MAC group was 42% compared with 56% among patients not readmitted (p=0.0026). Similarly, OS in the RIC group was 26% compared with 50% (p<0.0001). The 5-year OS for those readmitted by day 100 following HSCT in the MAC group was 52% compared with 61% among patients not readmitted (p=0.058) and in the RIC group was 26% compared with 57% (p=<0.0001). After adjusting for age, donor type, and the disease risk index (DRI), a multivariate analysis confirmed that readmission within 30 days of discharge or by day 100 was associated with decreased OS (table 1). Conclusions Infection and fever without a source were the most common causes of readmission after HSCT. In the RIC group, disease, transplant, and sociodemographic factors were associated with readmission. Being readmitted within 30 days of discharge from transplant was a significant risk factor for a lower 5-year overall survival rate in both the RIC and MAC groups. A better understanding of the risk factors for readmission in the HSCT population will allow for more transitional care and clinical resources to be focused on the highest risk patients. Strategies to decrease readmissions may improve the overall survival of patients undergoing allogeneic HSCT. More research is needed to better learn how to balance early discharge with preventable readmissions. Disclosures: No relevant conflicts of interest to declare.

Abstract After allogeneic hematopoietic stem cell transplantation (HSCT), late infections represent a major cause of morbidity and mortality but little has been previously reported. In a retrospective cohort study, late infections incidence was determined in 196 long-term survivors after matched related HSCT. Only patients transplanted for aplastic anemia, chronic myeloid leukemia (CML) and acute myeloblastic leukemia (AML) were included in this study. Median follow-up was 8 years. Among 30 patients who died beyond the first year, 9 patients died from graft-versus-host disease (GVHD) and 10 from infections. Bacterial late severe infections occurred in 30 patients, yielding an 8-year cumulative incidence of 15%. Late invasive fungal infection occurred in 8 patients corresponding to a cumulative incidence of 3.6%. Most viral infections were hepatitis C and VZV and overall late viral infection incidence was 35%. We identified 3 risk factors for bacterial infections in multiple analysis: CMV status (positive recipient and negative donor), irradiation based conditioning regimen and extensive chronic GVHD within the first year. Extensive chronic GVHD was the only risk factor of non-HCV viral infection in patients transplanted for AML or CML. Thus, late life threatening infections may occur in nearly a fourth of late survivors even after matched related transplantation and are associated not only with chronic GVHD but also with irradiation and to CMV status prior to transplantation.

Safety And Efficacy

ObjectiveThe objective of this study was to evaluate the safety and efficacy of sirolimus (SRL) in the prevention of graft-versus-host disease (GVHD) in recipients following allogeneic hematopoietic stem cell transplantation (allo-HSCT).MethodsRandomized controlled trials (RCTs) evaluating the safety and efficacy of SRL-based prophylaxis regimens in patients receiving allo-HSCT were obtained from PubMed, Embase, and the Cochrane database. Following specific inclusion and exclusion criteria, studies were selected and screened by two independent reviewers who subsequently extracted the study data. The Cochrane risk bias evaluation tool was used for quality evaluation, and RevMan 5.3 software was used for statistical analysis comparing the effects of SRL-based and non–SRL-based regimens on acute GVHD, chronic GVHD, overall survival (OS), relapse rate, non-relapse mortality (NRM), thrombotic microangiopathy (TMA), and veno-occlusive disease (VOD).ResultsSeven studies were included in this meta-analysis, with a total sample size of 1,673 cases, including 778 cases of patients receiving SRL-based regimens and 895 cases in which patients received non-SRL-based regimens. Our data revealed that SRL containing prophylaxis can effectively reduce the incidence of grade II–IV acute GVHD (RR = 0.75, 95% CI: 0.68∼0.82, p &lt; 0.0001). SRL-based prophylaxis was not associated with an improvement of grade III–IV acute GVHD (RR = 0.78, 95% CI: 0.59∼1.03, p = 0.08), chronic GVHD (p = 0.89), OS (p = 0.98), and relapse rate (p = 0.16). Despite its immunosuppressant effects, SRL-based regimens did not increase bacterial (p = 0.68), fungal (p = 0.70), or CMV (p = 0.10) infections. However, patients receiving SRL-based regimens had increased TMA (p &lt; 0.00001) and VOD (p &lt; 0.00001).ConclusionsThis meta-analysis indicates that addition of sirolimus is an effective alternative prophylaxis strategy for II–IV aGVHD but may cause endothelial cell injury and result in secondary TMA or VOD events.

Abstract Purpose Hepatic sinusoidal obstruction syndrome (SOS), which is also known as veno-occlusive disease of the liver, represents a serious complication following hematopoietic stem cell transplantation (HSCT). Our study aimed to investigate important risk factors for SOS in a pediatric population. Methods This retrospective study analyzed 105 children who underwent allogeneic HSCT at our pediatric HSCT center in Jena. The observation period was 12 years and SOS was defined by the modified pediatric Seattle criteria up to day +30 after HSCT. Results 15 out of all 105 patients developed SOS (14.3%). The median time from HSCT to SOS diagnosis was 12 days. The mortality rate of SOS was only 20.0%. In univariate analysis, we identified the significant risk factors of a patient age < 1 year (odds ratio (OR) = 7.25, p = 0.037) and a prior treatment with gemtuzumab ozogamicin (OR = 11.00, p = 0.020). In addition, some laboratory values, which were taken before HSCT, had a significant association to SOS. Ferritin > 1500 ng/mL (OR = 4.00, p = 0.033), ferritin > 2000 ng/mL (OR = 4.69, p = 0.016), ferritin > 2400 ng/mL (OR = 5.29, p = 0.005) and the international normalized ratio (INR) ≥ 1.3 (OR = 5.91, p = 0.009) showed significant results in univariate analysis. The following risk factors could be confirmed in multivariate analysis: prior treatment with gemtuzumab ozogamicin (OR = 9.24, p = 0.048), ferritin > 2400 ng/mL (OR = 5.74, p = 0.023) and INR ≥ 1.3 (OR = 8.02, p = 0.007).Conclusion Our study confirms several risk factors for hepatic SOS following allogeneic HSCT in pediatric patients. In addition, we report for the first time a significant association between high INR before HSCT and hepatic SOS, which consequently could improve the SOS risk evaluation.

Abstract Sporadic cases of successful non-T-cell-depleted (TCD) hematopoietic stem cell transplantation (SCT) from HLA-haploidentical family members mismatched for noninherited maternal antigens (NIMAs) have been reported over the last few years. This kind of SCT is based on the hypothesis that long-term feto-maternal microchimerism is associated with acquired immunologic hyporesponsiveness to NIMA or inherited paternal antigens (IPAs). To confirm the effectiveness and safety of NIMA-mismatched SCT in a large cohort, we retrospectively surveyed the outcomes of 76 children (44 boys, 32 girls; median age 7 years, range, 0–18) with either advanced non-malignant disorders (n=10), hematological malignancies (n=62) or solid tumors (n=4) who underwent T-cell-replete HLA-2-loci- or HLA-3-loci incompatible SCT from NIMA-mismatched donors (mother, n=53; NIMA-mismatched sibling, n=12) or other family donors (father/NIPA-mismatched sibling) (n=11) between 01/2000 and 12/2004. Disease status of malignant disease at SCT was as follows: CR1/CR2/CP in 19 and chemorefractory in 47. Types of grafts were bone marrow in 40 and peripheral blood stem cells in 35. Feto-maternal michrochimerism was detected in 32 out of 35 mothers tested and 8 out of 8 NIMA-mismatched sibling donors. GVHD prophylaxis consisted of tacrolimus-based regimen in 73. All but two patients achieved sustained neutrophil engraftment at median of 16.5 days (range, 10–29). Grade II to IV acute GVHD occurred in 36 of 73 evaluable patients (49%) between days 7 and 36 (median, 17). In non-malignant disorders, no severe (grade III/IV) acute GVHD was observed, while in malignant disorders, severe acute GVHD occurred in 21 (32%) of 65 evaluable patients. Twenty-two out of 41 evaluable patients (54%) who survived more than 6 months had extensive chronic GVHD. As of 04/2005, in non-malignant disorders, all 9 patients who obtained engraftment were alive. In malignant disorders, twenty-nine out of 66 patients (44%) were alive and 25 of them were disease-free with median follow-up of 25 (range, 4 to 57) months. Death were due to disease progression (n=22), infection (n=6), GVHD (n=4) and others (n=4). These results suggest that pediatric patients who lack immediate access to a conventional stem cell source can obtain successful results with non-TCD transplants from an HLA-haploidentical NIMA-mismatched donor.

Abstract Background WNT signaling pathway is known to have important functions in embryogenesis, cellular proliferation and regeneration, stem cell renewal and oncogenesis. DAAM2 is one of the key protein of WNT/PCP signaling pathway. This study examines the association of DAAM2 polymorphism and the clinical outcomes in patients treated with allogeneic hematopoietic stem cell transplantation (HSCT). Objectives and methods Candidate SNPs associated with acute graft versus host disease (GVHD) were selected using DNA chip analysis with Illumina Infinium Human-1 microarrays™ in 15 patients who treated with allogeneic HSCT for various hematologic and oncologic diseases with or without acute GVHD. Six SNPs (rs2504787, rs2504086, rs2504082, rs3004067, rs882559, and rs3004070) on DAAM2 were proven to be associated with acute GVHD, and extended genotyping was executed by Taqman™ protocol in more large population of 239 patients in single institute. Retrospective analysis for medical records was performed to define correlation of these SNPs with clinical outcomes of the patients. Results rs882559 located upstream from exon 24, was proven to be associated with acute GVHD incidence. Acute GVHD incidence was significantly lower in the patients with CC genotype of rs882559 than those with CG or GG genotype (HR 0.466, 95% CI 0.224∼0.969, p=0.0409). The allele frequency of C was 55% and that of G 44%. The genotyping disclosed CC in 77, CG in 110, and GG in 52. Multivariate analyses on various parameters including sex, age, transplant method (reduced intensity conditioning vs. conventional conditioning), stem cell source, risk group, and DAAM2 genotypes, as parameters, identified high-risk group defined in our previous study (KH Lee et al., Haematologica, 2007;92 ; HR 2.41, 95% CI 1.47∼3.94, p<0.001), age over 50 years (HR 1.70, 95% CI 1.18∼2.45, p=0.004) and codominant genotype of rs2504082, i.e., an intron mutation upsteam from exon 15 (HR 1.326, 95% CI 1.02∼1073, p=0.0378) as risk factors for a shorter survival. Interpretation and conclusions This is the first clinical study for the DAAM2 polymorphism, furthermore, and its association with clinical outcomes of allogeneic HSCT. The role of rs882559 and rs2504082 were not identified by now, but its mutation might affect to the transcription of following coding genes causing the changes of its functions. This study suggested the clinical value of DAAM2 polymorphism as a predictive parameter of clinical outcomes of allogeneic HSCT, and its importance in WNT signaling pathway.

Abstract The interaction between killer cell immunoglobin-like receptor (KIR) and HLA molecule has particular relevance to the unrelated hematopoietic stem cell transplantation (HSCT). The presence of KIR on donor’s NK cells and the absence of the corresponding KIR ligand in the recipient’s HLA repertoire as a receptor-ligand model can be used to predict the outcome of HSCT. To investigate the effect of KIR-HLA receptor-ligand mismatching and the expression of inhibitory KIR (iKIR) on the unrelated Allo-HSCT of leukemia, the following study has been carried out. The KIR genotypes of 36 patients of ALL (n=18), AML (n=10), and CML (n=8) as well as their unrelated donors were obtained from the Database of China Marrow Donor Program. KIR genotyping was performed with PCR-SSP. The KIR and HLA mismatching status (receptor-ligand mismatch model) between recipients and donors was analyzed thereafter. The expression of iKIR was determined by flow cytometry on recipients after HSCT. All cases were followed up closely until July, 2007. Among all the donor/recipient pairs analyzed, 15 pairs displayed the matched pattern with respect to the KIR genotyping though, graft-versus-host (GVH) KIR ligand-mismatched in 13 pairs, and host-versus-graft (HVG) KIR ligand-mismatched in 8 pairs. 26 recipients were lack of HLA-Cw2,4,5,6,15 ligands although iKIR/2DL1 was expressed on their corresponding donors. Similarly, 35 donors with iKIR/2DL2/L3 on their NK cells could recognized HLA- Cw1,3,7,8,12,14 ligands in their recipients. iKIR/3DL1 was expressed on 9 donors although the correlated HLA-Bw4 ligand was absent on the recipients. iKIR/3DL2 was expressed on 24 donors although the correlated HLA-A11 ligand was absent on the recipients. Except for one case, 35 patients were successfully transplanted, in which seven patients were dead, giving the survival rate of 80.0%. The cause of death was either acute/chronic GVHD or relapse. The frequency of acute GVHD (60.0%, 9/15), leading to death (26.7%, 4/15), was the highest in KIR receptor-ligand matched model. The incidence of acute GVHD and death was 30.8% (4/13) and 23.1% (3/13) in the GVH KIR ligand-mismatching, respectively; while the incidence of chronic GVHD was 37.5% (3/8) and no death happened in HVG KIR ligand-mismatching pattern. The expression of iKIR/2DL1 could be detected on ALL (13.0%∼16.6%) and CML (1.8∼6.2%) patients four month after HSCT. The expression of both iKIR/2DL1 (4%) and iKIR/2DL2 (12%) was found only in one patient with CML three month after HSCT, increased to 33.4% and 32.6% accompanied by cGVHD, and dropped to 7.6% and 10.3% one year after HSCT. These results suggested that the deficiency in iKIR/2DL1 based on the KIR-HLA receptor-ligand mismatching model together with the expression of a number of activating KIR in recipients increases the occurrence of GVHD, relapse, and death in unrelated HSCT. Analysis on KIR-HLA gene expression profiling could be useful in predicting the clinical outcome of unrelated Allo-HSCT in leukemia patients. The overall and disease-free survival after HSCT could be improved by preventing the development of GVHD.
