Biobehavioral mechanisms underlying symptoms in cancer patients with chronic graft-versus-host disease.

Chronic Graft Versus Host Disease (cGVHD) is a complication of allogeneic hematopoietic cell transplant (HCT) associated with morbidity and high symptom burden. This study evaluated two biobehavioral mechanisms, inflammation and circadian rest-activity rhythms, that may underly commonly reported psychological and physical symptoms in cGVHD patients. Adults with cGVHD (N=57) wore a wrist actigraph for 7 days, provided a blood sample, and completed patient-reported outcome (PRO) measures. 24-hour rest-activity indices were derived from actigraphy. Cytokines and chemokines relevant to cGVHD were measured in peripheral blood plasma using multi-analyte immunoassays. Multiple regression evaluated the extent to which rest-activity indices and inflammatory biomarkers predicted PROs. Higher levels of circulating IL-8 and MIP-1α were associated with worse depression (ß = 0.35, p = 0.01; ß = 0.33, p = 0.02) and sexual function (ß = -0.41, p = 0.01; ß = -0.32, p = 0.03). MIP-1α was associated with more severe insomnia (ß = 0.36, p = 0.01). Higher circulating MIF was associated with more severe anxiety (ß = 0.28, p = 0.048) and fatigue (ß = 0.35, p = 0.02). Il-6, TNFα, and MCP-1 showed few associations with PROs. There were few associations between actigraphy indices and PROs; however, participants with a later daily activity peak (acrophase) reported poorer sexual function (ß = -0.31, p = 0.04). Models covarying for age, cGVHD severity, and time since HCT yielded a similar pattern of results. Results suggest that pro-inflammatory cytokines and chemokines associated with cGVHD may contribute to PROs, identifying a biobehavioral mechanism that may be a useful target for future interventions.

Belumosudil for chronic graft-versus-host disease after 2 or more prior lines of therapy: the ROCKstar Study.

Belumosudil, an investigational oral selective inhibitor of Rho-associated coiled-coil-containing protein kinase 2 (ROCK2), reduces type 17 and follicular T helper cells via downregulation of STAT3 and enhances regulatory T cells via upregulation of STAT5. Belumosudil may effectively treat patients with chronic graft-versus-host disease (cGVHD), a major cause of morbidity and late nonrelapse mortality after an allogeneic hematopoietic cell transplant. This phase 2 randomized multicenter registration study evaluated belumosudil 200 mg daily (n = 66) and 200 mg twice daily (n = 66) in subjects with cGVHD who had received 2 to 5 prior lines of therapy. The primary end point was best overall response rate (ORR). Duration of response (DOR), changes in Lee Symptom Scale score, failure-free survival, corticosteroid dose reductions, and overall survival were also evaluated. Overall median follow-up was 14 months. The best ORR for belumosudil 200 mg daily and 200 mg twice daily was 74% (95% confidence interval [CI], 62-84) and 77% (95% CI, 65-87), respectively, with high response rates observed in all subgroups. All affected organs demonstrated complete responses. The median DOR was 54 weeks; 44% of subjects have remained on therapy for ≥1 year. Symptom reduction with belumosudil 200 mg daily and 200 mg twice daily was reported in 59% and 62% of subjects, respectively. Adverse events (AEs) were consistent with those expected in patients with cGVHD receiving corticosteroids and other immunosuppressants. Sixteen subjects (12%) discontinued belumosudil because of possible drug-related AEs. Belumosudil, a promising therapy for cGVHD, was well tolerated with clinically meaningful responses. This trial was registered at www.clinicaltrials.gov as #NCT03640481.

Association between the choice of the conditioning regimen and outcomes of allogeneic hematopoietic cell transplantation for myelofibrosis.

Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only curative treatment for myelofibrosis. However, the optimal conditioning regimen either with reduced-intensity conditioning (RIC) or myeloablative conditioning (MAC) is not well known. Using the Center for International Blood and Marrow Transplant Research database, we identified adults aged ≥18 years with myelofibrosis undergoing allo-HCT between 2008-2019 and analyzed the outcomes separately in the RIC and MAC cohorts based on the conditioning regimens used. Among 872 eligible patients, 493 underwent allo-HCT using RIC (fludarabine/ busulfan n=166, fludarabine/melphalan n=327) and 379 using MAC (fludarabine/busulfan n=247, busulfan/cyclophosphamide n=132). In multivariable analysis with RIC, fludarabine/melphalan was associated with inferior overall survival (hazard ratio [HR]=1.80; 95% confidenec interval [CI]: 1.15-2.81; P=0.009), higher early non-relapse mortality (HR=1.81; 95% CI: 1.12-2.91; P=0.01) and higher acute graft-versus-host disease (GvHD) (grade 2-4 HR=1.45; 95% CI: 1.03-2.03; P=0.03; grade 3-4 HR=2.21; 95%CI: 1.28-3.83; P=0.004) compared to fludarabine/busulfan. In the MAC setting, busulfan/cyclophosphamide was associated with a higher acute GvHD (grade 2-4 HR=2.33; 95% CI: 1.67-3.25; P<0.001; grade 3-4 HR=2.31; 95% CI: 1.52-3.52; P<0.001) and inferior GvHD-free relapse-free survival (GRFS) (HR=1.94; 95% CI: 1.49-2.53; P<0.001) as compared to fludarabine/busulfan. Hence, our study suggests that fludarabine/busulfan is associated with better outcomes in RIC (better overall survival, lower early non-relapse mortality, lower acute GvHD) and MAC (lower acute GvHD and better GRFS) in myelofibrosis.

Inflammatory cytokines and depression symptoms following hematopoietic cell transplantation.

Increased synthesis and release of inflammatory signalling proteins is common among individuals with hematologic malignancies undergoing hematopoietic cell transplantation (HCT) due to intensive conditioning regimens and complications such as graft-versus-host-disease and infections. Prior research indicates that inflammatory responses can activate central nervous system pathways that evoke changes in mood. This study examined relationships between markers of inflammatory activity and depression symptoms following HCT. Individuals undergoing allogeneic (n = 84) and autologous (n = 155) HCT completed measures of depression symptoms pre-HCT and 1, 3, and 6 months post-HCT. Proinflammatory (IL-6, TNF-α) and regulatory (IL-10) cytokines were assessed by ELISA in peripheral blood plasma. Mixed-effects linear regression models indicated that patients with elevated IL-6 and IL-10 reported more severe depression symptoms at the post-HCT assessments. These findings were replicated when examining both allogeneic and autologous samples. Follow-up analyses clarified that relationships were strongest for neurovegetative, rather than cognitive or affective, symptoms of depression. These findings suggest that anti-inflammatory therapeutics targeting an inflammatory mediator of depression could improve quality of life of HCT recipients.

Predictors of posttraumatic growth among hematopoietic cell transplant recipients.

OBJECTIVE: Prior research has shown that cancer survivors often report positive psychological changes from the experience of cancer, or posttraumatic growth (PTG). However, few studies have focused on PTG in cancer patients recovering from hematopoietic cell transplantation (HCT). The present study measured PTG at specific milestones during the year following HCT and investigated psychosocial and treatment-related factors that may hinder or facilitate PTG. METHODS: Participants (N = 430) completed assessments of PTG, social support, and coping pre-transplant. Posttraumatic growth was also assessed at 1, 3, 6, and 12 months post-transplant. Information about treatment regimen and post-transplant complications was abstracted from medical records. Mixed-effects linear regression models were used to evaluate the extent to which pre-transplant social support, coping approaches, treatment intensity, and post-transplant complications predicted PTG. RESULTS: Compared to pre-transplant, PTG scores were significantly higher at 6- and 12-month post-transplant. Greater pre-transplant social support significantly predicted greater PTG across the assessment points. Use of emotional engagement coping strategies also strongly predicted post-transplant PTG. Conversely, coping styles characterized by emotional avoidance generally were not predictive of PTG. No treatment-related factors or post-transplant complications were predictive of PTG. CONCLUSIONS: Findings indicate that supportive social relationships and coping by engaging with difficult emotions may facilitate PTG following HCT. Moreover, these factors were more important than medical characteristics in explaining PTG. Findings may guide the development of interventions to enhance positive psychological outcomes after HCT.

Barriers and facilitators to the use of survivorship care plans by hematopoietic stem cell transplant survivors and clinicians.

PURPOSE: Survivors of hematopoietic stem cell transplants (HSCT) have complex care needs for the remainder of their lives, known as the survivorship period. Survivorship care plans (SCPs) have been proposed to improve care coordination and ultimately survivorship outcomes. We explored the barriers and facilitators of SCP use among HSCT survivors and their clinicians in order to develop more useful SCPs for the HSCT context. METHODS: Analogous surveys regarding perceived barriers to and facilitators of SCP use based on a sample SCP for a female allogenic HSCT survivor were administered to HSCT survivors and non-transplant oncology and primary care clinicians. RESULTS: Twenty-seven HSCT survivors and 18 clinicians completed the survey. The main barriers to SCP use were lack of awareness of SCP existence, uncertainty regarding where to find SCP, unclear roles and responsibilities among healthcare teams, length of SCP, and difficultly understanding SCPs. The facilitators of SCP use were increased understanding of survivorship care needs, clarified roles and responsibilities of survivors and clinicians, SCPs that are readily available and searchable in electronic health record, increased awareness of SCP existence and provision to all survivors, and if the SCP is survivor-specific and up-to-date. CONCLUSIONS: Much of the work regarding SCPs has looked at barriers to creation and provision; however, our study examines factors influencing use of SCPs. By determining the barriers and facilitators surrounding SCP use for HSCT survivors and their clinicians, we can create SCP templates and clinical workflows to optimize SCP use, ideally leading to better outcomes for HSCT survivors.

Blood and Marrow Transplant Clinical Trials Network Study 1102 heralds a new era in hematopoietic cell transplantation in high-risk myelodysplastic syndromes: Challenges and opportunities in implementation.

LAY SUMMARY: People who have advanced myelodysplastic syndromes (MDS) may live longer if they get a bone marrow transplant (BMT) instead of other therapies. However, only 15% of people with MDS actually get BMT. Experts say community physicians and transplant physicians should team up with insurance companies and patient advocacy groups to 1) spread this news about lifesaving advances in BMT, 2) ensure that everyone can afford health care, 3) provide emotional support for patients and families, 4) help patients and families get transportation and housing if they need to travel for transplant, and 5) improve care for people of under-represented racial and ethnic backgrounds.

Maintenance Tyrosine Kinase Inhibitors Following Allogeneic Hematopoietic Stem Cell Transplantation for Chronic Myelogenous Leukemia: A Center for International Blood and Marrow Transplant Research Study.

It remains unknown whether the administration of tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 after allogeneic hematopoietic cell transplantation (HCT) is associated with improved outcomes for patients with chronic myelogenous leukemia (CML). In this registry study, we analyzed clinical outcomes of 390 adult patients with CML who underwent transplantation between 2007 and 2014 and received maintenance TKI following HCT (n = 89) compared with no TKI maintenance (n = 301), as reported to the Center for International Blood and Marrow Transplant Research. All patients received TKI therapy before HCT. The majority of patients had a disease status of first chronic phase at HCT (n = 240; 62%). The study was conducted as a landmark analysis, excluding patients who died, relapsed, had chronic graft-versus-host disease, or were censored before day +100 following HCT. Of the 89 patients who received TKI maintenance, 77 (87%) received a single TKI and the other 12 (13%) received multiple sequential TKIs. The most common TKIs used for maintenance were dasatinib (n = 50), imatinib (n = 27), and nilotinib (n = 27). As measured from day +100, the adjusted estimates for 5-year relapse (maintenance, 35% versus no maintenance, 26%; P = .11), leukemia-free survival (maintenance, 42% versus no maintenance, 44%; P = .65), or overall survival (maintenance, 61% versus no maintenance, 57%; P = .61) did not differ significantly between patients receiving TKI maintenance or no maintenance. These results remained unchanged in multivariate analysis and were not modified by disease status before transplantation. In conclusion, our data from this day +100 landmark analysis do not demonstrate a significant impact of maintenance TKI therapy on clinical outcomes. The optimal approach to TKI administration in the post-transplantation setting in patients with CML remains undetermined.

Hematopoietic Cell Transplantation, Version 2.2020, NCCN Clinical Practice Guidelines in Oncology

Hematopoietic cell transplantation (HCT) involves the infusion of hematopoietic progenitor cells into patients with hematologic disorders with the goal of re-establishing normal hematopoietic and immune function. HCT is classified as autologous or allogeneic based on the origin of hematopoietic cells. Autologous HCT uses the patient's own cells while allogeneic HCT uses hematopoietic cells from a human leukocyte antigen-compatible donor. Allogeneic HCT is a potentially curative treatment option for patients with certain types of hematologic malignancies, and autologous HCT is primarily used to support patients undergoing high-dose chemotherapy. Advances in HCT methods and supportive care in recent decades have led to improved survival after HCT; however, disease relapse and posttransplant complications still commonly occur in both autologous and allogeneic HCT recipients. Allogeneic HCT recipients may also develop acute and/or chronic graft-versus-host disease (GVHD), which results in immune-mediated cellular injury of several organs. The NCCN Guidelines for Hematopoietic Cell Transplantation focus on recommendations for pretransplant recipient evaluation and the management of GVHD in adult patients with malignant disease.

Survivor and Clinician Assessment of Survivorship Care Plans for Hematopoietic Stem Cell Transplantation Patients: An Engineering, Primary Care, and Oncology Collaborative for Survivorship Health.

The long-term care of hematopoietic stem cell transplantation (HSCT) survivors poses special challenges owing to a myriad of possible chronic and/or late complications. Survivorship care plans (SCPs) have been proposed as tools to communicate information on the late effects of treatment and recommended follow-up care to clinicians and survivors. The primary aims of this study were to determine SCP content and format, as well as to assess the preferred timing of SCP provision following HSCT. HSCT survivors and nontransplantation clinicians (oncologists and primary care physicians) were invited to participate in a survey evaluating the usefulness and utility of a sample HSCT-specific SCP with a treatment summary generated by autopopulation from an electronic health record (EHR). All participating HSCT survivors (n = 29) and clinicians (n = 18) indicated a desire to receive an SCP. More than 85% of the participants perceived information about treatments received, recommended follow-up and health maintenance including vaccinations, survivor and clinician resources, and graft-versus-host disease and other late/chronic side effects to be useful. The majority of survivors also believed that care team contact information was useful. In addition, >85% of survivors and clinicians agreed that the SCP increased their understanding of treatments and chronic/late side effects, improved health care provided, and were satisfied with the SCP and found it understandable and easy to use. The majority of survivors indicated that additional information should be added to the SCP, whereas some clinicians deemed the SCP too long. Survivors preferred to receive the SCP as a paper document at the end of a regular follow-up visit and review it with a cancer clinician, whereas clinicians preferred to receive the SCP through the EHR. These findings will help improve the design of future SCPs for use by HSCT survivors and clinicians. Future work will include leveraging the EHR to ease the burden of creating user-centered documents.

Illness perceptions predict health practices and mental health following hematopoietic stem cell transplantation.

OBJECTIVE: Beliefs about illness have been shown to shape health practices and coping efforts. The present study investigated illness perceptions among patients undergoing hematopoietic stem cell transplant (HSCT). We also examined the extent to which perceptions predicted health practices and mental health following transplant. METHODS: Participants (N = 332) completed measures of illness perceptions (beliefs about cancer consequences and course, personal and treatment control over cancer, and understanding of one's cancer) prior to HSCT. Health practices (diet, physical activity, and alcohol use) and mental health (depression, anxiety, and psychological well-being) were assessed pre transplant and at 1, 3, 6, and 12 months post transplant. RESULTS: On average, HSCT recipients felt they understood their cancer, viewed their cancer to be a chronic condition with severe consequences, and believed they had moderate personal control over their cancer but that medical treatment provided more control. Perceptions varied by transplant type. Mixed-effects linear regression models revealed that HSCT recipients who perceived the consequences of their cancer to be more serious experienced more depression and anxiety, less well-being, and ate a healthier diet, but were less physically active during the year following transplant. Those with greater personal and treatment control ate a healthier diet and reported greater well-being. Patients with a better understanding of their cancer also ate a healthier diet and reported less depression, less anxiety, and greater well-being. CONCLUSIONS: Perceptions of cancer shape HSCT recipients' health practices and psychological well-being during the critical first year of recovery after transplant.

Mindfulness, Experiential Avoidance, and Recovery From Hematopoietic Stem Cell Transplantation.

BACKGROUND: Mood disturbance, pain, and fatigue are prevalent and distressing concerns for patients with hematologic cancer recovering from hematopoietic stem cell transplantation (HSCT). The way in which individuals approach difficult thoughts and emotions may affect symptoms and functioning. Specifically, mindfulness has been associated with more optimal psychological and physical functioning, whereas experiential avoidance has been associated with poorer outcomes. PURPOSE: The primary objective was to determine whether mindfulness and experiential avoidance measured prior to HSCT were associated with recovery of psychological and physical functioning following HSCT. We also evaluated dimensions of mindfulness to determine which were most robustly associated with outcomes. METHODS: Participants completed measures of mindfulness and experiential avoidance prior to HSCT. Depression and anxiety symptoms and pain and fatigue interference with daily activities were assessed prior to HSCT and 1, 3, and 6 months post-HSCT. RESULTS: Participants who reported better ability to describe their internal experiences and who were better able to act with awareness experienced less depression, anxiety, and fatigue interference following HSCT. Participants who were nonjudgmental and nonreactive toward thoughts and emotions experienced less depression and anxiety following HSCT, but these traits were not associated with pain or fatigue interference. Being a good observer of internal experiences was not associated with outcomes, nor was experiential avoidance. CONCLUSIONS: Results suggest that most facets of mindfulness may optimize psychological functioning following HSCT, and the ability to describe one's internal experience and to focus on the present moment may have a beneficial influence on physical functioning.

Choosing Wisely BMT: American Society for Blood and Marrow Transplantation and Canadian Blood and Marrow Transplant Group's List of 5 Tests and Treatments to Question in Blood and Marrow Transplantation.

Choosing Wisely encourages dialogue about reducing unnecessary procedures, tests, or treatments in healthcare. The American Society for Blood and Marrow Transplantation (ASBMT) and Canadian Blood and Marrow Transplant Group (CBMTG) established a Choosing Wisely BMT Task Force whose objective was to create a list of top 5 practices in blood and marrow transplantation to be questioned. The Task Force consisted of representatives from ASBMT's Quality Outcomes, Education, and Practice Guidelines committees; ASBMT's Pharmacy Special Interest Group; CBMTG Program Directors; and Center for International Blood and Marrow Transplant Research (CIBMTR). Suggestions for current transplantation practices to question were elicited from the CBMTG Program Directors; members of ASBMT's Quality Outcomes, Practice Guidelines, and Education committees; and chairs of the CIBMTR scientific working committees. We received 119 unique suggestions that were ranked based on their potential impact on harm reduction, cost reduction, necessity of the test or practice, and the strength of available evidence. Through a modified Delphi process, suggestions were narrowed down to 6, which were then subjected to systematic reviews. The final 5 recommendations focus on graft source for patients with aplastic anemia, corticosteroid dose for initial treatment of graft-versus-host-disease, optimal number of umbilical cord blood units for transplantation, graft source in matched unrelated donor transplantation, and use of prophylactic intravenous immunoglobulin in transplant recipients. These Choosing Wisely BMT recommendations are relevant to the current clinical practice of blood and marrow transplantation and focus on tests, treatments, or procedures that may be harmful, wasteful, or for which there is no apparent clinical benefit.

Engaging Patients in Setting a Patient-Centered Outcomes Research Agenda in Hematopoietic Cell Transplantation.

The goal of patient-centered outcomes research (PCOR) is to help patients and those who care for them make informed decisions about healthcare. However, the clinical research enterprise has not involved patients, caregivers, and other nonproviders routinely in the process of prioritizing, designing, and conducting research in hematopoietic cell transplantation (HCT). To address this need the National Marrow Donor Program/Be The Match engaged patients, caregivers, researchers, and other key stakeholders in a 2-year project with the goal of setting a PCOR agenda for the HCT community. Through a collaborative process we identified 6 major areas of interest: (1) patient, caregiver, and family education and support; (2) emotional, cognitive, and social health; (3) physical health and fatigue; (4) sexual health and relationships; (5) financial burden; and (6) models of survivorship care delivery. We then organized into multistakeholder working groups to identify gaps in knowledge and make priority recommendations for critical research to fill those gaps. Gaps varied by working group, but all noted that a historical lack of consistency in measures use and patient populations made it difficult to compare outcomes across studies and urged investigators to incorporate uniform measures and homogenous patient groups in future research. Some groups advised that additional pre-emptory work is needed before conducting prospective interventional trials, whereas others were ready to proceed with comparative clinical effectiveness research studies. This report presents the results of this major initiative and makes recommendations by working group on priority questions for PCOR in HCT.

Improved survival after acute graft-versus-host disease diagnosis in the modern era.

A cute graft-versus-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-versus-host disease. We examined outcome following diagnosis of grade II-IV acute graft-versus-host disease according to time period, and explored effects according to original graft-versus-host disease prophylaxis regimen and maximum overall grade of acute graft-versus-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-versus-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-versus-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 (P<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 (P=0.003) and treatment-related mortality (P=0.008) were only noted among those originally treated with tacrolimus-based graft-versus-host disease prophylaxis, and these effects were most apparent among those with overall grade II acute graft-versus-host disease. In conclusion, survival has improved over time for tacrolimus-treated transplant recipients with acute graft-versus-host disease.

Myelodysplastic Syndromes, Version 2.2017, NCCN Clinical Practice Guidelines in Oncology.

The myelodysplastic syndromes (MDS) comprise a heterogenous group of myeloid disorders with a highly variable disease course. Diagnostic criteria to better stratify patients with MDS continue to evolve, based on morphology, cytogenetics, and the presence of cytopenias. More accurate classification of patients will allow for better treatment guidance. Treatment encompasses supportive care, treatment of anemia, low-intensity therapy, and high-intensity therapy. This portion of the guidelines focuses on diagnostic classification, molecular abnormalities, therapeutic options, and recommended treatment approaches.

Safety and efficacy of autologous serum eye drop for treatment of dry eyes in graft-versus-host disease.

PURPOSE: To evaluate the treatment of autologous serum eye drops (ASED) on dry eyes in patients with graft-versus-host disease (GVHD). METHODS: A retrospective chart review of 35 patients with a history of ocular GVHD following hematopoietic stem cell transplantation that used ASED to alleviate dry eye symptoms was performed. Patients were categorized into three different groups. If patients had available ophthalmic data before and after starting treatment was group 1 (n = 14), had available ophthalmic data after starting treatment in group 2 (n = 10) and had available ophthalmic data before treatment or did not have any data after starting treatment in group 3 (n = 11). Data were collected on patient's age, gender, primary diagnosis, visual acuity and fluorescein corneal staining were collected on individual eyes in order to evaluate the efficacy of the ASED on alleviating dry eye-related signs and symptoms. RESULTS: No adverse ocular effect from the ASED was found in our series (except one fungal keratitis). All patients reported either improvement (55%) or stability (45%) in their ocular symptoms upon the use of ASED. In patients with available data before and after starting treatment, the corneal staining score improved by a median of 1 (p = 0.003) and the LogMAR visual acuity had a non-significant improvement. CONCLUSION: In our study, ASED used by patients with ocular GVHD were both safe and effective. ASED should be considered in patients with GVHD who suffer from dry eyes.

Success of an International Learning Health Care System in Hematopoietic Cell Transplantation: The American Society of Blood and Marrow Transplantation Clinical Case Forum.

The American Society for Blood and Marrow Transplantation (ASBMT) Clinical Case Forum (CCF) was launched in 2014 as an online secure tool to enhance interaction and communication among hematopoietic cell transplantation (HCT) professionals worldwide through the discussion of challenging clinical care issues. After 14 months, we reviewed clinical and demographical data of cases posted in the CCF from January 29, 2014 to March 18, 2015. A total of 137 cases were posted during the study period. Ninety-two cases (67%) were allogeneic HCT, 29 (21%) were autologous HCT, and in 16 (12%), the type of transplantation (autologous versus allogeneic) was still under consideration. The diseases most frequently discussed included non-Hodgkin lymphoma (NHL; n = 30, 22%), acute myeloid leukemia (n = 23, 17%), and multiple myeloma (MM; n = 20, 15%). When compared with the US transplantation activity reported by the US Department of Health and Human Services, NHL and acute lymphoblastic leukemia cases were over-represented in the CCF, whereas MM was under-represented (P < .001). A total of 259 topics were addressed in the CCF with a median of 2 topics/case (range, 1 to 6). Particularly common topics included whether transplantation was indicated (n = 57, 41%), conditioning regimen choice (n = 44, 32%), and post-HCT complications after day 100 (n = 43, 31%). The ASBMT CCF is a successful tool for collaborative discussion of complex cases in the HCT community worldwide and may allow identification of areas of controversy or unmet need from clinical, educational and research perspectives.

Azacitidine with or without Entinostat for the treatment of therapy-related myeloid neoplasm: further results of the E1905 North American Leukemia Intergroup study.

Therapy-related myeloid neoplasms (tMN) are serious late effects of the treatment of cancer with poor response to conventional treatment. Azacitidine (AZA) has been used to treat patients with tMN but current data are retrospective. We present here 47 tMN patients prospectively enrolled as a specific cohort in the E1905 study. TheE1905 study was a randomized phase 2 study (NCT00313586) testing 10 d of AZA (50 mg/m(2) /d) +/- the histone deacetylase inhibitor entinostat (4 mg/m(2) /d PO day-3 and day-10). A total of 47 patients [29 therapy-related myelosyspastic syndrome (t-MDS) and 18 therapy-related acute myeloid leukaemia (t-AML)] were recruited to the study. 24 patients were treated with AZA monotherapy and 23 with AZA+entinostat. The median number of administered cycles was 4, significantly higher in patients treated with AZA (6 cycles vs. 3 cycles, P = 0·008). Haematological normalization rates were 46% in monotherapy and 17% in the combination arm. Median overall survivals were 13 and 6 months, respectively. The novel 50 * 10 schedule of azacitidine appears effective, with response rates, when given as single agent, comparable to those for patients with de novo MDS/AML treated on the same protocol. However, the combination of AZA and entinostat was associated with increased toxicity and could not be recommended for treatment of tMN.
