A cute graft-
-host disease remains a major threat to a successful outcome after allogeneic hematopoietic cell transplantation. While improvements in treatment and supportive care have occurred, it ...is unknown whether these advances have resulted in improved outcome specifically among those diagnosed with acute graft-
-host disease. We examined outcome following diagnosis of grade II-IV acute graft-
-host disease according to time period, and explored effects according to original graft-
-host disease prophylaxis regimen and maximum overall grade of acute graft-
-host disease. Between 1999 and 2012, 2,905 patients with acute myeloid leukemia (56%), acute lymphoblastic leukemia (30%) or myelodysplastic syndromes (14%) received a sibling (24%) or unrelated donor (76%) blood (66%) or marrow (34%) transplant and developed grade II-IV acute graft-
-host disease (n=497 for 1999-2001, n=962 for 2002-2005, n=1,446 for 2006-2010). The median (range) follow-up was 144 (4-174), 97 (4-147) and 60 (8-99) months for 1999-2001, 2002-2005, and 2006-2010, respectively. Among the cohort with grade II-IV acute graft-
-host disease, there was a decrease in the proportion of grade III-IV disease over time with 56%, 47%, and 37% for 1999-2001, 2002-2005, and 2006-2012, respectively (
<0.001). Considering the total study population, univariate analysis demonstrated significant improvements in overall survival and treatment-related mortality over time, and deaths from organ failure and infection declined. On multivariate analysis, significant improvements in overall survival (
=0.003) and treatment-related mortality (
=0.008) were only noted among those originally treated with tacrolimus-based graft-
-host disease prophylaxis, and these effects were most apparent among those with overall grade II acute graft-
-host disease. In conclusion, survival has improved over time for tacrolimus-treated transplant recipients with acute graft-
-host disease.
Chronic graft-versus-host disease (GvHD) treatment response is assessed using National Institutes of Health (NIH) Consensus Criteria in clinical trials, and by clinician assessment in routine ...practice. Patient-reported treatment response is central to the experience of chronic GvHD manifestations as well as treatment benefit and toxicity, but how they correlate with clinician- or NIH-responses has not been well-studied. We aimed to characterize 6-month patientreported response, determine associated chronic GvHD baseline organ features and changes, and evaluate which patientreported quality of life and chronic GvHD symptom burden measures correlated with patient-reported response. From two nationally representative Chronic GVHD Consortium prospective observational studies, 382 subjects were included in this analysis. Patient and clinician responses were categorized as improved (completely gone, very much better, moderately better, a little better) versus not improved (about the same, a little worse, moderately worse, very much worse). At six months, 270 (71%) patients perceived chronic GvHD improvement, while 112 (29%) perceived no improvement. Patient-reported response had limited correlation with either clinician-reported (kappa 0.37) or NIH chronic GvHD response criteria (kappa 0.18). Notably, patient-reported response at six months was significantly associated with subsequent failure-free survival. In multivariate analysis, NIH responses in eye, mouth, and lung had significant association with 6-month patient-reported response, as well as a change in Short Form 36 general health and role physical domains and Lee Symptom Score skin and eye changes. Based on these findings, patient-reported responses should be considered as an important complementary endpoint in chronic GvHD clinical trials and drug development.
Background
Consolidation chemotherapy, autologous hematopoietic cell transplantation (HCT) and allogeneic HCT represent potential treatment alternatives for post‐remission therapy in adult acute ...lymphoblastic leukemia (ALL), but there is genuine uncertainty regarding the optimal approach.
Objectives
To assess the effect of matched sibling donor vs. no donor status for adults with ALL in first complete remission (CR1).
Search methods
We performed a search of CENTRAL, MEDLINE and EMBASE electronic databases in September 2010 along with handsearching of literature cited in relevant primary articles, search of s from American Society of Hematology and American Society of Clinical Oncology meetings, as well as consultation with content experts in the field.
Selection criteria
Review was performed by two authors, and Inclusion criteria included the following: controlled trials with donor vs. no donor comparison with assignment by genetic randomizationin adults with ALL in CR1.
Data collection and analysis
We extracted data on benefits (overall survival, progression‐free survival) and harms (treatment‐related mortality, relapse) of compared treatments. Adverse events were considered, but analysis of individual adverse events was not possible from the reported literature. We pooled summary results from each study using a random‐effects model. We assessed heterogeneity. We performed subgroup analyses for disease risk categories. We performed sensitivity analyses according to methodological quality.
Main results
A total of 14 relevant trials were identified, consisting of a total of 3157 patients. There was a statistically significant overall survival advantage in favor of the donor versus no donor group (HR 0.86; 95% CI 0.77 to 0.97; P = 0.01), as well as significant improvement in disease‐free survival in the donor group(HR 0.82; 95% CI 0.72 to 0.94; P = 0.004). Those in the donor group had significant reduction in primary disease relapse(RR 0.53; 95% CI 0.37 to 0.76; P = 0.0004) and significant increase in non‐relapse mortality(RR 2.8; 95% CI 1.66 to 4.73; P = 0.001). Significant heterogeneity was detected in analysis of relapse (Chi2 40.51, df = 6, P < 0.00001; I2 = 85%). In regard to methodologic quality, the majority of included studies were free of selective reporting, and performed analyses according to intention to treat. Conversely, few reported sample size calculation that informed the study design. While blinding was considered as an important domain of methodological quality, none of the studies reported on whether any of the study personnel were blinded (e.g. subjects, personnel, outcome assessors, data analysts etc). Therefore, we did not consider blinding further in the analysis of methodological quality in this review.
Authors' conclusions
The results of this systematic review and meta‐analysis support matched sibling donor allogeneic hematopoietic cell transplantation as the optimal post‐remission therapy in ALL patients aged 15 years or over. This therapy offers superior overall survival and disease‐free survival, and significantly reduces the risk of disease relapse, but does impose an increased risk of non‐relapse mortality. Importantly these data are based on adult ALL treated with largely total body irradiation‐based myeloablative conditioning and sibling donor transplantation and, therefore, cannot be generalized to pediatric ALL, alternative donors including HLA (human leukocyte antigen) mismatched or unrelated donors, or reduced toxicity or non‐myeloablative conditioning regimens.
The natural history of lung function in patients with bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic cell transplant is poorly characterized. Understanding the trajectory of ...lung function is necessary for prompt clinical recognition and treatment and also for the rational design of prospective studies.
To describe the longitudinal trajectory of lung function parameters, including FEV
, in patients with BOS after hematopoietic cell transplant.
Subjects with BOS defined by National Institutes of Health consensus guidelines criteria from a recent multicenter prospective trial of combination treatment with fluticasone, azithromycin and montelukast and a retrospective cohort from Fred Hutchinson Cancer Research Center were included. Longitudinal change in FEV
for each patient was calculated on the basis of available pulmonary function tests in three periods: pre-BOS, from BOS diagnosis to 6 months, and 6-18 months after diagnosis. The effect of treatment on FEV
trajectory was analyzed by univariate and multivariate linear regression. The Kaplan-Meier method was used to estimate survival.
The FEV
percent predicted value at diagnosis was 46% (interquartile range, 35-57%) for trial participants and 53% (interquartile range, 41-64%) for the retrospective cohort. There was a concomitant mild reduction in FVC, as well as a marked reduction in forced expiratory flow, midexpiratory phase, at diagnosis. While there was individual heterogeneity, the overall FEV
trajectory was characterized by a marked decline within 6 months prior to BOS diagnosis, followed by stability of FEV
early after diagnosis and a slow rate of decline beyond 6 months. The effect of the trial medications on FEV
trajectory after BOS diagnosis was a mean rate of change of 0.92% predicted per month (95% confidence interval, -0.53 to 2.37) compared with the retrospective cohort, but this was not statistically significant. Two-year overall survival rates were 76% and 72% for the study participants and the retrospective cohort patients, respectively. Earlier time to diagnosis after hematopoietic cell transplant and severity of FVC at diagnosis were significantly associated with reduced survival.
The FEV
trajectory in patients with BOS after hematopoietic cell transplant in a contemporary era of management follows a predominant pattern of rapid FEV
decline in the 6 months prior to diagnosis, followed by FEV
stabilization after diagnosis.
The application of machine learning in medicine has been productive in multiple fields, but has not previously been applied to analyze the complexity of organ involvement by chronic graft-
-host ...disease. Chronic graft-
-host disease is classified by an overall composite score as mild, moderate or severe, which may overlook clinically relevant patterns in organ involvement. Here we applied a novel computational approach to chronic graft-
-host disease with the goal of identifying phenotypic groups based on the subcomponents of the National Institutes of Health Consensus Criteria. Computational analysis revealed seven distinct groups of patients with contrasting clinical risks. The high-risk group had an inferior overall survival compared to the low-risk group (hazard ratio 2.24; 95% confidence interval: 1.36-3.68), an effect that was independent of graft-
-host disease severity as measured by the National Institutes of Health criteria. To test clinical applicability, knowledge was translated into a simplified clinical prognostic decision tree. Groups identified by the decision tree also stratified outcomes and closely matched those from the original analysis. Patients in the high- and intermediate-risk decision-tree groups had significantly shorter overall survival than those in the low-risk group (hazard ratio 2.79; 95% confidence interval: 1.58-4.91 and hazard ratio 1.78; 95% confidence interval: 1.06-3.01, respectively). Machine learning and other computational analyses may better reveal biomarkers and stratify risk than the current approach based on cumulative severity. This approach could now be explored in other disease models with complex clinical phenotypes. External validation must be completed prior to clinical application. Ultimately, this approach has the potential to reveal distinct pathophysiological mechanisms that may underlie clusters.

Chronic graft-versus-host disease (GVHD) is a pleotropic syndrome that lacks validated methods of measuring response in clinical trials, although several end points have been proposed. To investigate ...the prognostic significance of these proposed end points, such as the 2005 National Institutes of Health (NIH) response measures, 2014 NIH response measures, clinician-reported response, and patient-reported response, we tested their ability to predict subsequent overall survival (OS), nonrelapse mortality (NRM), and failure-free survival (FFS). Patients (n = 575) were enrolled on a prospective chronic GVHD observational trial. At 6 months, clinician-reported response (P = .004) and 2014 NIH-calculated response (P = .001) correlated with subsequent FFS, and clinician-reported response predicted OS (P = .007). Multivariate models were used to identify changes in organ involvement, laboratory values, and patient-reported outcomes that were associated with long-term outcomes. At 6 months, a change in the 2005 NIH 0 to 3 clinician-reported skin score and 0 to 10 patient-reported itching score predicted subsequent FFS. Change in the Lee skin symptom score and Functional Assessment of Cancer Therapy–Bone Marrow Transplant score predicted subsequent OS. Change in the Lee skin symptom score predicted subsequent NRM. This study provides evidence that clinician-reported response and patient-reported outcomes are predictive of long-term survival. The trial was registered at www.clinicaltrials.gov as #NCT00637689.
•Survival of chronic GVHD patients was predicted by clinician-assessed response and changes in patient-reported outcomes.•FFS was predicted by clinician-assessed response, changes in patient-reported outcomes, and the 2014 NIH response criteria.
Background
Allogeneic hematopoietic stem cell transplantation (allo‐HCT) is associated with improved outcomes for people with various hematologic diseases; however, the morbidity and mortality ...resulting from acute and subsequently chronic graft‐versus‐host disease (GVHD) pose a serious challenge to wider applicability of allo‐HCT. Intravenous methotrexate in combination with a calcineurin inhibitor, cyclosporine or tacrolimus, is a widely used regimen for the prophylaxis of acute GVHD, but the administration of methotrexate is associated with a number of adverse events. Mycophenolate mofetil, in combination with a calcineurin inhibitor, has been used extensively in people undergoing allo‐HCT. Conflicting results regarding various clinical outcomes following allo‐HCT have been observed when comparing mycophenolate mofetil‐based regimens against methotrexate‐based regimens for acute GVHD prophylaxis.
Objectives
Primary objective: to assess the effect of mycophenolate mofetil versus methotrexate for prevention of acute GVHD in people undergoing allo‐HCT.
Secondary objectives: to evaluate the effect of mycophenolate mofetil versus methotrexate for overall survival, prevention of chronic GVHD, incidence of relapse, treatment‐related harms, nonrelapse mortality, and quality of life.
Search methods
We searched Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE from inception to March 2014. We handsearched conference s from the last two meetings (2011 and 2012) of relevant societies in the field. We searched ClinicalTrials.gov, Novartis clinical trials database (www.novctrd.com), Roche clinical trial protocol registry (www.roche‐trials.com), Australian New Zealand Clinical Trials Registry (ANZCTR), and the metaRegister of Controlled Trials for ongoing trials.
Selection criteria
Two review authors independently reviewed all titles/s and selected full‐text articles for inclusion. We included all references that reported results of randomized controlled trials (RCTs) of mycophenolate mofetil versus methotrexate for the prophylaxis of GVHD among people undergoing allo‐HCT in this review.
Data collection and analysis
Two review authors independently extracted data on outcomes from all studies and compared prior to data entry and analysis. We expressed results as risk ratios (RR) and 95% confidence intervals (CI) for dichotomous outcomes and hazard ratios (HR) and 95% CIs for time‐to‐event outcomes. We pooled the individual study effects using the random‐effects model. Estimates lower than one indicate that mycophenolate mofetil was favored over methotrexate.
Main results
We included three trials enrolling 177 participants (174 participants analyzed). All participants in the trials by Keihl et al. and Bolwell et al. received cyclosporine while all participants enrolled in the trial by Perkins et al. received tacrolimus. However, the results did not differ by the type of calcineurin inhibitor employed (cyclosporine versus tacrolimus). There was no evidence for a difference between mycophenolate mofetil versus methotrexate for the outcomes of incidence of acute GVHD (RR 1.25; 95% CI 0.75 to 2.09; P value = 0.39, very low quality evidence), overall survival (HR 0.73; 95% CI 0.45 to 1.17; P value = 0.19, low‐quality evidence), median days to neutrophil engraftment (HR 0.77; 95% CI 0.51 to 1.17; P value = 0.23, low‐quality evidence), incidence of relapse (RR 0.84; 95% CI 0.52 to 1.38; P value = 0.50, low‐quality evidence), non‐relapse mortality (RR 1.21; 95% CI 0.62 to 2.36; P value = 0.57, low‐quality evidence), and incidence of chronic GVHD (RR 0.92; 95% CI 0.65 to 1.30; P value = 0.62, low‐quality evidence). There was low‐quality evidence that mycophenolate mofetil compared with methotrexate improved platelet engraftment period (HR 0.87; 95% CI 0.81 to 0.93; P value < 0.0001, low‐quality evidence). There was low‐quality evidence that mycophenolate mofetil compared with methotrexate resulted in decreased incidence of severe mucositis (RR 0.48; 95% CI 0.32 to 0.73; P value = 0.0006, low‐quality evidence), use of parenteral nutrition (RR 0.48; 95% CI 0.26 to 0.91; P value = 0.02, low‐quality evidence), and medication for pain control (RR 0.76; 95% CI 0.63 to 0.91; P value = 0.002, low‐quality evidence). Overall heterogeneity was not detected in the analysis except for the outcome of neutrophil engraftment. None of the included studies reported any outcomes related to quality of life. Overall quality of evidence was low.
Authors' conclusions
The use of mycophenolate mofetil compared with methotrexate for primary prevention of GVHD seems to be associated with a more favorable toxicity profile, without an apparent compromise on disease relapse, transplant‐associated mortality, or overall survival. The effects on incidence of GVHD between people receiving mycophenolate mofetil compared with people receiving methotrexate were uncertain. There is a need for additional high‐quality RCTs to determine the optimal GVHD prevention strategy. Future studies should take into account a comprehensive view of clinical benefit, including measures of morbidity, symptom burden, and healthcare resource utilization associated with interventions.
Cutaneous sclerosis occurs in 20% of patients with chronic graft-versus-host disease (GVHD) and can compromise mobility and quality of life.
We conducted a prospective, multicenter, randomized, ...two-arm phase II crossover trial of imatinib (200 mg daily) or rituximab (375 mg/m(2) i.v. weekly × 4 doses, repeatable after 3 months) for treatment of cutaneous sclerosis diagnosed within 18 months (NCT01309997). The primary endpoint was significant clinical response (SCR) at 6 months, defined as quantitative improvement in skin sclerosis or joint range of motion. Treatment success was defined as SCR at 6 months without crossover, recurrent malignancy or death. Secondary endpoints included changes of B-cell profiles in blood (BAFF levels and cellular subsets), patient-reported outcomes, and histopathology between responders and nonresponders with each therapy.
SCR was observed in 9 of 35 26%; 95% confidence interval (CI); 13%-43% participants randomized to imatinib and 10 of 37 (27%; 95% CI, 14%-44%) randomized to rituximab. Six (17%; 95% CI, 7%-34%) patients in the imatinib arm and 5 (14%; 95% CI, 5%-29%) in the rituximab arm had treatment success. Higher percentages of activated B cells (CD27(+)) were seen at enrollment in rituximab-treated patients who had treatment success (P = 0.01), but not in imatinib-treated patients.
These results support the need for more effective therapies for cutaneous sclerosis and suggest that activated B cells define a subgroup of patients with cutaneous sclerosis who are more likely to respond to rituximab.
