Abstract
Objective: To explore clinical features and severity of chronic graft- versus- host disease (cGVHD) after chemotherapy plus donor lymphocyte infusion (Chemo-DLI) in a consecutive cohort of acute leukemia patients who were minimal residual disease (MRD) positive after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: The global scoring system proposed by National Institutes of Health (NIH) Consensus Conference was used to identify the characteristics and severity of cGVHD in patients who MRD positive after Chemo-DLI. Results: 54 (59.3%) patients were diagnosed with cGVHD after Chemo-DLI, with the median time of onset of 70 (13-504) days. There were 6 cases (6.6%) of mild cGVHD, 21 cases (23.1%) of moderate cGVHD and 27 cases (29.7%) of severe cGVHD.The 5-year cumulative incidence of relapse after Chemo-DLI was 61.9% (95%CI 45.3%-78.5%) , 15.1% (95%CI 1.1%-29.1%) , and 26.6% (95%CI 9.2%-44.0%) (chi(2)=18.901, P<0.001) in non-cGVHD, mild to moderate cGVHD, and severe cGVHD groups, respectively. The 5-year cumulative incidence of relapse after Chemo-DLI was 61.9% (95%CI 45.3%-78.5%) , 19.9% (95%CI 8.1%-31.7%) , and 28.6% (95%CI 0.0%-65.0%) (chi(2)=18.307, P<0.001) in non-cGVHD, classical cGVHD, and overlap syndrome groups, respectively. cGVHD was not associated with non-relapse morality after Chemo-DLI. Probabilities of 5-year leukemia-free survival (LFS) after Chemo-DLI were 24.0% (95%CI 9.1%-38.9%) , 77.2% (95%CI 60.8%-93.6%) , and 64.9% (95%CI 45.7%-84.1%) (chi(2)=24.447, P<0.001) in non-cGVHD, mild to moderate cGVHD, and severe cGVHD groups, respectively. Probabilities of 5-year LFS after Chemo-DLI were 24.0% (95%CI 9.1%-38.9%) , 75.5% (95%CI 62.7%-88.3%) , and 42.9% (95%CI 1.8%-84.0%) (chi(2)=25.665, P<0.001) in non-cGVHD, classical cGVHD, and overlap syndrome groups, respectively. Probabilities of 5-year overall survival (OS) after Chemo-DLI were 50.0% (95%CI 31.1%-68.9%) , 87.9% (95%CI 74.7%-100.0%) , and 71.0% (95%CI 52.0%-90.0%) (chi(2)=9.517, P=0.009) in non-cGVHD, mild to moderate cGVHD, and severe cGVHD groups, respectively. Probabilities of 5-year OS after Chemo-DLI were 50.0% (95%CI 31.1%-68.9%) , 83.9% (95%CI 72.8%-95.0%) , and 51.4% (95%CI 6.2%-96.6%) (chi(2)=10.673, P=0.005) in non-cGVHD, classical cGVHD, and overlap syndrome groups, respectively. In multivariate analysis, patients receiving allo-HSCT in first complete remission stage and classical cGVHD after Chemo-DLI were associated with lower relapse risk and better survival. Conclusions: These findings highlight the close relation between cGVHD and the graft-versus-leukemia effect in patients who were MRD positive and received Chemo-DLI after allo-HSCT. However, overlap syndrome could not improve the clinical outcomes of these patients.

Abstract
The aim of this study was to investigate the occurrence and severity of chemotherapy plus donor lymphocyte infusion (Chemo-DLI) associated chronic graft-versus-host disease (cGVHD) in a consecutive cohort of patients with acute leukemia who experienced relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT; n=104). The 5-year cumulative incidence of complete remission (CR) after Chemo-DLI was 81.0% (95% CI, 73.3-88.7%) and 84.6% (95% CI, 74.5-94.7%) in the moderate and severe cGVHD groups, respectively, which was significantly higher than that of the mild cGVHD 40.9% (95% CI, 29.3-52.5%) and non-cGVHD groups 29.2% (95% CI 23.1-35.3%). The cumulative incidence of non-relapse mortality was comparable between patients with and without cGVHD. The 5-year probabilities of progression-free survival after Chemo-DLI were 42.9% (95% CI, 26.2-70.2%) and 34.6% (95% CI, 15.3-78.2%) in moderate and severe cGVHD groups, respectively, which were both significantly higher than those of mild cGVHD 9.1% (95% CI, 2.4-34.1%) and non-cGVHD groups 8.3% (95% CI 3.3-21.3%). The 5-year probabilities of overall survival after Chemo-DLI were 56.7% (95% CI, 38.9-82.7%) and 43.1% (95% CI, 22.1-84.0%), in moderate and severe cGVHD groups, respectively, which were both significantly higher than those of the mild cGVHD 9.1% (95% CI 1.8-47.1%) and non-cGVHD groups 14.9% (95% CI, 7.3-30.2%). Our observations highlight the close relation between cGVHD and immune-mediated graft-versus-leukemia (GVL) effect in patients with relapse receiving Chemo-DLI; however, mild cGVHD may not be associated with a sufficiently strong GVL effect to induce remission and improve survival.

Abstract
We analyzed the use of low-dose alemtuzumab in a cohort of 158 consecutive patients who underwent allogeneic PBSC transplantation. Patients with high-risk acute leukemia were prospectively screened for prophylactic donor lymphocyte infusion (pDLI). Lymphocytes were administered repeatedly at low and non-escalating doses (0.5-1 x 106/kg). Low-dose alemtuzumab was effective in prevention of acute GvHD after sibling or well-matched unrelated transplantation, whereas a more intensified approach was needed after mismatched transplantation. The cumulative incidence of chronic moderate/severe chronic-GvHD (cGvHD) was 15.6%. In total, 63 high-risk leukemia patients were eligible for pDLI. Only 1 out of the 39 pDLI recipients relapsed as compared with 7 out of the 24 recipients, who did not receive pDLI due to logistical hurdles. In multivariate analysis, the use of adjuvant lymphocyte therapy was significantly associated with reduced incidence of relapse and improved disease-free survival. In summary, low-dose alemtuzumab confers to a low cGvHD incidence and the administration of pDLIs in this context is very likely to reduce relapse risk in high risk leukemia patients. This is translated in an estimated 5-year probability of GvHD-free and relapse-free survival of 43.3% for the 136 leukemia patients.

Abstract
OBJECTIVE To investigate the incidence and risk factors of sclerodermatous chronic graft-versus-host disease (ScGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS The clinical data of 259 patients undergoing allo-HSCT in Nanfang Hospital between January, 2012 and December, 2014 were analyzed. RESULTS Chronic GVHD following allo-HSCT occurred in 134 (51.7%) cases, among whom 22 patients showed sclerodermatous features at a median of 12.5 months (range 4-28 months) after the transplantation. The overall incidence of ScGVHD was 8.49% (22/259) in the recipients and 16.4% (22/134) in those with cGVHD. Univariate analysis showed that the conditioning regimen with total body irradiation (P=0.031), GVHD prophylaxis with MMF (P=0.046), presence of chronic GVHD (P=0.008), and donor lymphocyte infusion (P=0.001) were all closely associated with the occurrence of ScGVHD. Multivariate analysis identified chronic GVHD (RR=3.512, 95%CI: 1.235-9.987, P=0.018) and donor lymphocyte infusion (RR=5.217, 95%CI: 1.698-16.029, P=0.004) as the independent risk factors of ScGVHD. CONCLUSION ScGVHD following allo-HSCT is not a common complication, and cGVHD and donor lymphocyte infusion are the independent risk factors for ScGVHD.
