Impact of GvHD on quality of life in long-term survivors of haematopoietic transplantation

A Biobehavioral Perspective on Caring for Allogeneic Hematopoietic Stem Cell Transplant Survivors with Graft-Versus-Host Disease

Among the potential complications of allogeneic hematopoietic stem cell transplantation (HSCT), graft-versus-host disease (GVHD) is common and associated with significant physical and psychosocial symptom burden. Despite substantial advances in GVHD treatment, the global immune suppression that frequently accompanies GVHD treatment also contributes to high rates of physical and emotional suffering and mortality. The complex manifestations of GVHD and its treatment warrant a multidisciplinary team-based approach to managing patients' multi-organ system comorbidities. A biobehavioral framework can enhance our understanding of the complex association between medications, physical symptoms, and psychosocial distress in patients with GVHD. Hence, for this perspective, we highlight the importance of addressing both the physical and psychosocial needs experienced by patients with GVHD and provide guidance on how to approach and manage those symptoms and concerns as part of comprehensive cancer care.

Allogeneic transplantation of bone marrow versus peripheral blood stem cells from HLA-identical sibling donors for hematological malignancies in 6064 adults from 2003 to 2020: different impacts on survival according to time period

BACKGROUND

Mobilized peripheral blood stem cells (PBSC) have been widely used instead of bone marrow (BM) as the graft source for allogeneic hematopoietic cell transplantation (HCT). Although early studies demonstrated no significant differences in survival between PBSC transplantation (PBSCT) and BM transplantation (BMT) from human leukocyte antigen (HLA)-identical sibling donors to adults with hematological malignancies, recent results have been unclear.

OBJECTIVE

The objective of this retrospective study was to compare overall survival (OS), relapse, non-relapse mortality (NRM), hematopoietic recovery and graft-versus-host disease (GVHD) between PBSCT and BMT according to the time period of HCT (2003-2008, 2009-2014, or 2015-2020).

STUDY DESIGN

We retrospectively compared the outcomes after PBSCT versus BMT in 6064 adults with hematological malignancies using a Japanese registry database between 2003 and 2020.

RESULTS

The adjusted probability of OS was significantly higher in BMT recipients compared to PBSCT recipients during the early period of 2003-2008 (adjusted hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.70-0.91; P < 0.001) and the middle period of 2009-2014 (adjusted HR, 0.80; 95% CI, 0.70-0.91; P < 0.001). However, during the late period of 2015-2020, the adjusted probability of OS was comparable between BMT and PBSCT recipients (adjusted HR, 0.94; 95% CI, 0.79-1.13; P = 0.564), which were mainly due to the reduction of NRM. There was no significant difference in the relapse rate between the groups, irrespective of the time period. Compared to BMT, PBSCT led to faster neutrophil and platelet recovery and the cumulative incidences of grades II-IV and grades III-IV acute and overall and extensive chronic GVHD were significantly higher in PBSCT recipients, irrespective of the time period.

CONCLUSIONS

PBSCT and BMT had similar survival outcomes and relapse rates in adult patients with hematological malignancies during the late time period of 2015-2020 despite the hematopoietic recovery and acute and chronic GVHD being higher in PBSCT recipients in all time periods.

Updates in hematopoietic cell transplant and cellular therapies that enhance the risk for opportunistic infections

BACKGROUND

Infectious disease physicians may be asked to evaluate and manage a variety of infections in immunocompromised hosts undergoing hematopoietic cell transplant (HCT) and cellular therapies. Over the last decade, several advances in cellular therapy have occurred, with implications for the types of infectious complications that may be seen.

AIMS

The purpose of this review is to update the infectious disease physician on newer advances in HCT and cellular therapy, including haploidentical transplant, expanding indications for transplant in older individuals and children, and chimeric antigen receptor T-cells. We will review how these advances might influence infectious disease complications following HCT. We will also provide a perspective that infectious disease physicians can use to evaluate the degree of immune suppression in an individual patient to help determine the type of infections that may be encountered.

Improved outcomes of UM171-expanded cord blood transplantation compared with other graft sources: real-world evidence

Cord blood (CB) transplantation is hampered by low cell dose and high nonrelapse mortality (NRM). A phase 1-2 trial of UM171-expanded CB transplants demonstrated safety and favorable preliminary efficacy. The aim of the current analysis was to retrospectively compare results of the phase 1-2 trial with those after unmanipulated CB and matched-unrelated donor (MUD) transplants. Data from recipients of CB and MUD transplants were obtained from the Center for International Blood and Marrow Transplant Research (CIBMTR) database. Patients were directly matched for the number of previous allogeneic hematopoietic stem cell transplants (alloHCT), disease and refined Disease Risk Index. Patients were further matched by propensity score for age, comorbidity index, and performance status. Primary end points included NRM, progression-free survival (PFS), overall survival (OS), and graft-versus-host disease (GVHD)-free relapse-free survival (GRFS) at 1 and 2 years after alloHCT. Overall, 137 patients from CIBMTR (67 CB, 70 MUD) and 22 with UM171-expanded CB were included. NRM at 1 and 2 years was lower, PFS and GRFS at 2 years and OS at 1 year were improved for UM171-expanded CBs compared with CB controls. Compared with MUD controls, UM171 recipients had lower 1- and 2-year NRM, higher 2-year PFS, and higher 1- and 2-year GRFS. Furthermore, UM171-expanded CB recipients experienced less grades 3-4 acute GVHD and chronic GVHD compared with MUD graft recipients. Compared with real-world evidence with CB and MUD alloHCT, this study suggests that UM171-expanded CB recipients may benefit from lower NRM and higher GRFS. This trial was registered at www.clinicaltrials.gov as #NCT02668315.

Triple-Drug Graft-versus-Host Disease Prophylaxis after HLA-Matched Unrelated Donor Nonmyeloablative Allogenic Hematopoietic Stem Cell Transplantation

Adding sirolimus to graft-versus-host disease (GVHD) prophylaxis with cyclosporin and mycophenolate mofetil (MMF) reduced the risk of grade II-IV acute GVHD after nonmyeloablative (NMA) allogenic hematopoietic stem cell transplantation (HSCT) with an HLA-matched unrelated donor in a randomized clinical trial. We analyzed real-life data to investigate the impact of implementing the triple-drug regimen with cyclosporin, MMF and sirolimus as standard GVHD prophylaxis after NMA HSCT with an HLA-matched unrelated donor at our institution. We studied all adult patients (age ≥18 years) who underwent NMA HSCT with an HLA-matched unrelated donor at Rigshospitalet, Copenhagen University Hospital, Denmark between 2018 and 2021 and received GVHD prophylaxis with cyclosporin, MMF and sirolimus (triple-drug group [TDG]). Comparisons were made with a historical cohort who received tacrolimus and MMF as GVHD prophylaxis after HLA-matched unrelated donor NMA HSCT between 2014 and 2017 (control group [CG]). Outcomes were grade II-IV and grade III-IV acute GVHD, chronic GVHD, relapse, nonrelapse mortality (NRM) and overall survival (OS). A total of 264 patients were included (TDG, n = 137; CG, n = 127). Median age was 66 years (interquartile range [IQR], 58 to 69 years) in the TDG and 63 years (IQR, 57 to 68 years) in the CG. Acute myeloid leukemia and myelodysplastic syndrome were the most frequent indications for HSCT in both groups (TDG, 33% and 23%, respectively; CG, 36% and 22%, respectively). The cumulative incidence at day +110 of grade II-IV GVHD was 17% (95% confidence interval [CI] 11% to 23%) in the TDG versus 29% (95% CI, 21% to 37%) in the CG (P = .02, Gray's test) and that of grade III-IV acute GVHD was 3% (95% CI, 0 to 6%) versus 5% (95% CI, 1% to 8%), respectively (P = .4, Gray's test). In a Cox regression model adjusted for age, donor age and female donor to male recipient the risk of grade II-IV acute GVHD was lower in the TDG compared to the CG (hazard ratio [HR], .51; 95% CI .30 to .86; P = .01). The 2-year OS was 77% (95% CI, 70% to 84%) in the TDG and 69% (95% CI, 61% to 77%) in the CG (P = .04), and this difference remained significant after adjustment for age and Karnofsky Performance Status (HR, .65; 95% CI, .42 to .99; P = .04). The 2-year cumulative incidences of chronic GVHD, relapse and NRM were 60% (95% CI, 51% to 69%), 21% (95% CI, 13% to 28%), and 12% (95% CI, 6% to 17%), respectively, in the TDG and 62% (95% CI, 54% to 71%), 27% (95% CI, 19% to 35%) and 14% (95% CI, 8% to 20%), respectively, in the CG. Multivariable analyses revealed no difference in the risk of chronic GVHD (HR, .91; 95% CI, .65 to 1.26; P = .56), relapse (HR, .70; 95% CI, .42 to 1.15; P = .16) or NRM (HR, .56; 95% CI, .31 to 1.05; P = .07). After changing the standard GVHD prophylaxis in patients undergoing NMA HSCT with an HLA-matched unrelated donor from tacrolimus and MMF to cyclosporin, MMF and sirolimus, we observed a reduction in the incidence of grade II-IV acute GVHD and improved 2-year OS.

Fatigue as Mediator Factor in PTSD-Symptoms after Allogeneic Hematopoietic Stem Cell Transplantation

BACKGROUND

Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is a valid treatment for hematological oncological or metabolic diseases. Despite its therapeutic efficacy, it is an aggressive treatment that impacts negatively on quality of life (QoL) and may result in Post-Traumatic Stress Disorder (PTSD) symptoms. The aim of this study is to explore rates and risk factors for PTSD symptoms, and fatigue in post-HSCT patients with hematological malignancies.

METHODS

A total of 123 patients after HSCT were evaluated for PTSD symptoms, QoL and fatigue. PTSD symptoms were assessed with the Impact of Event Scale- Revised (IES-R), QoL was measured with Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) and fatigue symptoms were assessed with Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F).

RESULTS

A total of 58.54% of the sample developed PTSD symptoms after transplant. Patients with PTSD symptoms reported significantly lower QoL total scores and significantly higher fatigue than those without PTSD symptoms (p < 0.001). The SEM analysis showed that worse QoL and fatigue affected PTSD symptomatology along different pathways. Fatigue was found as a major influencing factor of PTSD symptoms directly (β = 0.31 **), while QoL only through the mediation of fatigue at a lesser extent. (β = 0.33 *).

CONCLUSIONS

Our findings indicate that QoL is a concurrent causative factor to the development of PTSD symptomatology through the mediating role of fatigue. Innovative interventions before transplantation to prevent PTSD symptoms should be investigated to improve survival and QoL in patients.

Fatigue in Hematopoietic Cell Transplantation Survivors: Correlates, Care Team Communication, and Patient-Identified Mitigation Strategies

With improved survival after hematopoietic cell transplantation (HCT), the number of individuals at risk for persistent or late effects is increasing. The importance of optimizing HCT survivor health and well-being is mounting. Fatigue is a common post-transplantation symptom that impairs quality of life, yet it remains poorly understood and inadequately addressed. Multiple challenges to addressing fatigue exist, including its multidimensional presentation, multiple (often concomitant) causes, patient-clinician communication barriers, and few highly effective, evidence-based interventions that can be readily implemented. To address these challenges, we sought to better describe the impact and potential causes of fatigue in the post-transplantation setting, fatigue-related communication with clinicians, and the most effective patient-identified mitigation strategies (PIMS) for fatigue. A total of 1703 adult HCT recipients from a single center completed a survey including the Medical Outcomes Survey Short Form-36 (SF-36), PROMIS Fatigue, and other fatigue-related items between July 2017-June 2018. The survey was offered to recipients at their post-transplantation anniversary occurring during this interval. Two independent raters categorized free-text responses about fatigue PIMS. PROMIS Fatigue scores were dichotomized into low (≤55) or high (>55). Associations between high fatigue and participant characteristics and health outcomes were evaluated using the Fisher exact test for categorical variables and the Student 2-sample t test for continuous variables. Among the 1660 respondents with evaluable fatigue scores, 67% underwent allogeneic HCT. The majority of these (n = 1588; 96%) had a malignancy, with hematologic malignancy the most common diagnostic category (n = 1555; 94%). The median time post-transplantation was 11 years (interquartile range, 4 to 20 years). PROMIS item responses indicate that 44% of patients were at least somewhat fatigued and 37% were at least somewhat bothered by it. The mean fatigue score was 50.2 ± 11; 591 patients (36%) had high fatigue, which was associated with worse SF-36 scores across all domains (General Health, Physical Functioning, Emotional Well-being/Mental Health, Social Functioning, Role Limitation due to Physical Health, Role Limitation due to Emotional Health, Vitality [eg, energy], and Bodily Pain). High fatigue also was associated with self-reported chronic graft-versus-host disease, anxiety, depression and sleep problems. Diagnosis of plasma cell disorder and receipt of an autologous transplant were associated with high fatigue (P = .001). Among the 553 individuals who received an autologous transplant, 226 (41%) had multiple myeloma. Compared with the autologous transplant recipients without myeloma group, those with multiple myeloma were significantly more likely to have high fatigue (109 of 226 [48%] versus 118 of 325 [36%]; P < .01). Twenty percent of the patients with high fatigue did not discuss it with their care team. Among the 89 different reasons provided for not discussing it, the most common was "thought they already knew the answer" (n = 21). The 370 survivors with high fatigue who identified at least 1 most effective PIMS generated a total of 639 PIMS. Although the PIMS for fatigue spanned a wide array of strategies, most PIMS were related to sleep/rest (n = 192; 30%) or exercise (n = 139; 22%). Although fatigue is associated with worse HCT survivor-reported outcomes, it is only sometimes discussed with care teams. Survivors identify specific strategies that are most effective. Given its prevalence and impact, clinicians should promote communication about fatigue, treat underlying causes, and recommend sleep/rest and exercise, recognizing that individualized approaches also may be beneficial.

Vision-specific and cancer-specific quality of life in ocular graft-versus-host disease after allogeneic hematopoietic stem cell transplantation

PURPOSE

To compare the vision-specific and cancer-specific quality of life (QOL) between patients with and without ocular graft-versus-host disease (oGVHD) after allogeneic hematopoietic stem cell transplantation (alloHCT).

METHODS

This cross-sectional observational study analyzed 142 patients after alloHCT including 94 patients with oGVHD and 48 without. oGVHD was diagnosed according to International Chronic Ocular GVHD Consensus Group (ICOGCG) criteria. QOL was assessed by using the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30).

RESULTS

Compared with non-oGVHD patients, patients with oGVHD had worse vision-specific (NEI VFQ-25: 64.3 ± 20.3 vs. 77.6 ± 19.3, P < 0.001) and cancer-specific (EORTC QLQ-C30: 59.9 ± 20.3 vs. 67.4 ± 17.5, P = 0.03) QOL, as well as impaired cognitive function (72.7 ± 22.1 vs. 82.3 ± 19.0, P = 0.01). The vision-specific QOL was significantly correlated with ICOGCG score (β =  - 1.88, 95%CI: - 3.35 to - 0.41, P = 0.01) and post-alloHCT medical expense (β =  - 5.70, 95%CI: - 10.35 to - 1.05, P = 0.02), while cancer-specific QOL was strikingly correlated with post-alloHCT medical expense (β =  - 9.91, 95%CI: - 14.43 to - 5.39, P < 0.001), frequency of ophthalmic medication (β =  - 0.93, 95%CI: - 1.64 to - 0.21, P = 0.01), education (β =  - 6.97, 95%CI: - 13.31 to - 0.62, P = 0.03), and peripheral blood stem cell use (β =  - 6.42, 95%CI: - 12.59 to - 0.25, P = 0.04).

CONCLUSIONS

Patients with oGVHD experienced significant impairment in both vision-specific and cancer-specific QOL including cognitive function when compared with those without after alloHCT. Multidimensional QOL assessment should be included in the long-term alloHCT survivorship care.

Patient-reported symptom burden and impact on daily activities in chronic graft-versus-host disease

BACKGROUND

Chronic graft-versus-host disease (GVHD) is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT) treatment for hematologic malignancies. There are limited patient-reported data concerning symptom burden and effects on activities of daily living (ADL).

METHODS

The cross-sectional Living With Chronic GVHD Patient Survey was administered online in the United States (May-August 2020) to participants aged ≥18 years who underwent allogeneic HSCT, were diagnosed with chronic GVHD by a healthcare provider, and self-reported active chronic GVHD (within past 5 years). Information on patient demographics, disease characteristics, symptom burden, and ability to perform ADL was collected. Symptom burden was assessed using the validated Lee Symptom Scale (range from 0-100 with higher scores indicating greater burden). All data were summarized using descriptive statistics; no formal statistical comparisons were conducted.

RESULTS

Out of 580 participants who entered the survey screener, 165 participants (28.4%) across 33 states fulfilled all study eligibility criteria, completed the entire survey, and were included (age: mean [SD], 53.7 (13.8) years; median [range], 57.0 [18-78] years; female, n = 105 [63.6%]; White, n = 137 [83.0%]). Respondents described their chronic GVHD severity primarily as moderate (n = 54 [32.7%]) or severe (n = 102 [61.8%]) at the time when symptoms were at their worst. One-third of respondents (33.9%) indicated that their chronic GVHD symptoms were at their worst for ≥1 year in duration. Mean (SD; range) Lee Symptom Scale score was 44.8 (19.4; 2-100); 44% of respondents considered "dry eye" the most burdensome symptom. Almost half of respondents (n = 73 [44.2%]) rated their overall quality of life (QoL) as poor. Participants reported a detrimental impact of symptoms on ADL, including basic activities (eg, eating, personal hygiene, dressing).

CONCLUSIONS

Survey respondents self-reported high chronic GVHD symptom burden and felt that their symptoms severely interfered with physical function and ADL. Effective strategies to mitigate chronic GVHD symptoms are needed to improve QoL among HSCT survivors.

Impact of Resistance Exercise and Nutritional Endorsement on physical performance in patients with GvHD (IRENE-G study) - design and rational of a randomized controlled trial

BACKGROUND

Graft-versus-host disease (GvHD) remains a major complication and limitation to successful allogeneic hematopoietic stem cell transplantation. Treatment of GvHD is challenging due to its heterogeneous nature of presentation, with steroids remaining the established first-line treatment. Long-term doses of systemic corticosteroids have many well-known side-effects including muscle atrophy. Despite the fact that reports in non-cancer clinical populations treated with glucocorticoids demonstrated that resistance training can reverse atrophy and weakness, no RCT has evaluated the potential of resistance training on preventing the disease- and treatment-induced loss of skeletal muscle mass and function in GvHD patients yet. In this context, ensuring adequate nutrition is important as protein deprivation may accelerate the wasting process. As GvHD patients are commonly found to be malnourished, nutritional medical care should be considered when investigating the effect of exercise in GvHD patients. Therefore, the aim of the present "Impact of Resistance Exercise and Nutritional Endorsement on physical performance in patients with GvHD" - Study (IRENE-G) is to evaluate the effects of resistance exercise in combination with nutritional endorsement on physical, nutritional and patient-reported outcomes in GvHD patients.

METHODS

IRENE-G is a 24-week prospective interventional RCT. One hundred twelve participants will be randomly allocated (1:1) to one of two arms: resistance exercise and nutritional optimization (experimental) vs. nutritional optimization only (control). Participants in the experimental group will engage in a supervised, progressive moderate-to-high intensity resistance training that is consistent with exercise guidelines for cancer patients, while additionally receiving nutritional support/therapy. Subjects of the control group solely receive nutritional support/therapy based on individual needs. Participants will be assessed at baseline, at 8, 16, 24 weeks for physical performance and various physiological, nutritional and patient-reported outcomes. Follow-up will be 6 months after intervention completion.

DISCUSSION

To our knowledge, this will be the first RCT to assess and compare the effects of a resistance intervention supplemented by nutritional support/therapy against nutritional support only on various health-related outcomes in GvHD patients. The study will contribute to our understanding of the value of exercise and nutritional endorsement in counteracting the negative consequences of GvHD and its treatment.

Oral manifestations of graft-versus-host disease in patients submitted to allogeneic hematopoietic stem cell transplantation: the experience of a Brazilian Cancer Center

PURPOSE

Graft-versus-host disease (GVHD) is an important complication of allogeneic hematopoietic stem cell transplantation (AHCT) that affects several organs, including the mouth.

OBJECTIVES

The aim of the present study was to describe the prevalence and clinical manifestations of oral GVHD, to determine the time interval from AHCT to the onset of oral GVHD manifestations, to identify predictive factors of oral GVHD, and to evaluate the survival rates of patients diagnosed with oral GVHD.

METHODS

Medical records of 147 patients who underwent AHCT between January 2010 and January 2015 were reviewed for clinical features and the statistical establishment of risk factors.

RESULTS

Of the 147 patients in the study, 99 (67.3%) developed GVHD. The skin was the most affected site (45.6%), followed by the gastrointestinal tract (27.9%) and oral cavity (17.7%). The mean post-AHCT oral GVHD development time was 229 days. Among patients with oral GVHD, pain was the main complaint (96.2%) followed by xerostomia (65.4%). The most common oral manifestations were ulcers (53.8%) followed by striae-associated ulcers (19.2%), mostly affecting the buccal mucosa and tongue. Seventy-three patients (48.6%) died within 20 months of receiving AHCT. Cox regression analysis indicated that patients who received myeloablative conditioning regimen had higher survival rate than those who underwent a reduced-intensity conditioning regimen (RR = 0.541; 95% CI, 0.334-0.878; p = 0.03).

CONCLUSION

The mouth was the third most common GVHD-affected site. Pain, xerostomia, and ulcers with or without striae were the main clinical manifestations of GVHD observed in our study cohort. Reduced-intensity conditioning regimen showed significant relationship with mortality risk.

Addition of Anti-thymocyte Globulin in Allogeneic Stem Cell Transplantation With Peripheral Stem Cells From Matched Unrelated Donors Improves Graft-Versus-Host Disease and Relapse Free Survival

Anti-thymocyte globulin (ATG) is commonly used to prevent graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). To evaluate the impact of ATG as part of the GvHD prophylaxis in our institution, we report the outcome of 415 patients with matched unrelated donors (MUD) transplanted for hematological malignancies with or without ATG from 2005 to 2019 at Oslo University Hospital, Norway. The following groups were compared: (1) 154 patients transplanted with peripheral blood stem cells (PBSC) without ATG 2005-2014. (2) 137 patients transplanted with bone marrow stem cells (BMSC) 2005-2019. (3) 124 patients transplanted with PBSC and ATG (PBSC + ATG) 2014-2019. Three years survival was similar in the groups, 61% following allografting with PBSC, 54% with BMSC, and 59% with PBSC + ATG. Acute GvHD grade III-IV was 14%, 14%, and 7%; chronic GvHD was 81%, 32, and 26%; and extensive cGvHD 44%, 15%, and 6% in the corresponding groups. Both acute and chronic GvHD were significantly reduced in the PBSC + ATG-versus the PBSC group (p < 0.05 and p < 0.001 respectively).Transplant-related mortality (TRM) was 33%, 25%, and 17% (p = 0.18). Graft versus host disease and relapse free survival (GRFS) at 3 years was 43 %, 43%, and 64% in the groups. Adding ATG to the GvHD prophylaxis regimen of MUD allo-HSCT with PBSC resulted in a substantial reduction of both acute and chronic GvHD without compromising the disease control, reflected in a superior 3 years GRFS.

Immune-mediated neuromuscular complications of graft-versus-host disease

INTRODUCTION/AIMS

We aimed to describe the clinical phenotype, histopathological findings and overall survival (OS) of the immune-mediated neuromuscular complications of graft-versus-host disease (GVHD).

METHODS

We conducted a retrospective chart review of adult patients presenting with immune-mediated neuromuscular complications of GVHD to Mayo Clinic, between April 2013 and July 2018.We collected clinical and laboratory characteristics, histopathological findings, response to treatment and survival data.

RESULTS

We identified 20 patients with a mean age at presentation of 55 y. Mean time from transplant to neurological presentation was 14 mo. Myositis was the most common complication seen in 17 patients, manifesting with predominantly axial and/or proximal weakness. Eleven patients had a muscle biopsy showing diffuse perimysial, predominantly macrophagic infiltration in 10, 3 of them with perimysial perivascular lymphocytic collections, and endomysial and perimysial lymphocytic infiltration in 1. Only two patients had a neuropathic complication: one each with acute inflammatory demyelinating polyradiculoneuropathy and neuralgic amyotrophy. A single patient had a myasthenic syndrome presenting with fluctuating foot drop. Nineteen patients were treated and all responded to immunosuppressive agents; however, 11 had further GVHD flares requiring escalation of therapy. After a median follow-up of 83 mo, seven (35%) patients died: five from progressive GVHD and two from infections. The 5-y OS from time of transplant was 68%.

DISCUSSION

Myositis is the most common immune-mediated neuromuscular complication of GVHD while peripheral neuropathy and myasthenic syndromes appear less common. The macrophage-predominant infiltration on muscle biopsy deserves further study to better clarify the role of macrophages in GVHD pathogenesis.

Predictors of quality of life in allogeneic hematopoietic stem cell transplantation survivors

OBJECTIVES

To establish the demographic, medical, transplant, and lifestyle factors that impact Quality of Life (QoL) in long-term survivors of allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT).

DESIGN

Cross-sectional study utilizing self-report measures.

SAMPLE/METHODS

In this cross-sectional study of 441 adult survivors of allo-HSCT, participants completed questionnaires assessing QoL, psychological, social, demographic, and clinical variables.

FINDINGS

Factors associated with improved QoL post-allo-HSCT included time since transplant, female gender, attendance at outpatient appointments, health screening uptake, exercise, and resumption of travel. Factors significantly associated with impaired QoL included chronic morbidities (GVHD), taking psychotropic medication, failure to resume sexual activity (in men), male gender, psychological distress, low income or decline in work status, transition to non-physical work, and necessity for post-allo-HSCT care from various health professionals.

IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS

Identification of survivors more likely to experience a reduced QoL following allo-HSCT may enable the targeting of health services to the most vulnerable, and the development of interventions and resources. The data from this study led to the development of HSCT Long-Term Follow Up Clinical Guidelines in New South Wales.

Impact of Low-Dose rATG Prior to Matched Sibling Donor Hematopoietic Stem Cell Transplantation for Hematologic Malignancies: Reduced Risk of Chronic Graft-versus-Host Disease and Improved Survival Outcomes

Purpose

To explore the efficacy of low-dose rabbit antithymocyte globulin (rATG) in matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT) for patients with acute leukemia or myelodysplastic syndrome.

Patients and Methods

We performed a retrospective study of 79 patients with hematologic malignancies who received MSD-HSCT. All patients received standard graft-versus-host disease (GVHD) prophylaxis comprising cyclosporine, mycophenolate mofetil and short-term methotrexate. Among them, 38 were administered 5 mg/kg rATG as part of GVHD prophylaxis. Clinical outcomes including overall survival (OS), GVHD and relapse were analyzed.

Results

No graft failure occurred in the antithymocyte globulin (ATG) or non-ATG group. The cumulative incidences of grade 2-4 and 3-4 acute GVHD at day +100 were 13.3% versus 19.5% (p=0.507) and 5.7% versus 15.2% (p=0.196), respectively. The 2-year cumulative incidences of chronic GVHD (cGVHD) were 35.4% and 60.4% (p=0.039), and those of extensive cGVHD were 12.9% and 40.0% (p=0.015), respectively. In a multivariate analysis, the use of low-dose rATG was an independent protective factor for extensive cGVHD (hazard ratio [HR] 0.256; 95% confidence interval [CI], 0.080 to 0.822, p=0.022). The 2-year OS was 88.1% and 68.4% (p=0.038), respectively, and the use of low-dose rATG was the only protective factor in the multivariate analysis (HR 0.216; 95% CI, 0.059 to 0.792, p=0.021). There was no significant difference between the two groups in terms of the 2-year cumulative incidence of relapse, leukemia-free survival or GVHD-free and relapse-free survival.

Conclusion

Low-dose rATG used in MSD-HSCT as part of the conditioning regimen results in a reduced incidence of cGVHD and improves survival outcomes.

Limbal and Conjunctival Epithelial Thickness in Ocular Graft-Versus-Host Disease

PURPOSE

To compare the thickness of the limbal epithelium (LE) and the bulbar conjunctival epithelium (BCE) between patients with dry eye disease (DED) with and without ocular graft-versus-host disease (GVHD).

METHODS

This cross-sectional study enrolled 40 patients with moderate to severe DED including 20 with and 20 without chronic ocular GVHD. All patients had a comprehensive clinical ophthalmic assessment. Moreover, the thickness of the LE and BCE in both nasal and temporal regions of both eyes was measured using spectral domain optical coherence tomography.

RESULTS

The average LE thickness in all patients with dry eye (GVHD and non-GVHD) was 65.8 ± 11.9 μm temporally and 69.7 ± 11.1 μm nasally (P = 0.02). The average BCE thickness was 55.8 ± 11.4 μm temporally and 60.1 ± 11.0 μm nasally (P = 0.03). There were no statistically significant differences between GVHD and non-GVHD groups in LE thickness (69.6 ± 11.7 vs. 66.1 ± 6.2 μm, respectively, P = 0.31) or BCE thickness (58.9 ± 9.6 vs. 57.3 ± 9.8 μm, respectively, P = 0.82). There was a significant correlation between LE thickness and BCE thickness (P = 0.01, Rs = 0.41). A statistically significant negative correlation was also observed between LE thickness and age (P = 0.002, Rs = -0.35). There were no significant correlations between the thickness of the LE or BCE and other clinical parameters.

CONCLUSIONS

No difference exists in the thickness of the ocular surface epithelia between dry eyes with and without ocular GVHD, which would suggest that these epithelial changes may be independent of the underlying etiology and possibly only reflect the disease severity. Furthermore, there are regional variations in the thickness of the ocular surface epithelia in patients with DED.

Utilization of Palliative Care for Patients Undergoing Hematopoietic Stem Cell Transplantation During Hospitalization: A Population-Based National Study

OBJECTIVE

Patients undergoing hematopoietic stem cell transplantation (HSCT) have substantial physical and psychological symptoms. This study aimed to investigate the utilization of palliative care (PC) in patients undergoing HSCT during hospitalization.

METHODS

The 2008-2014 National Inpatient Sample was queried for eligible participants. Demographics, hospital characteristics, comorbidities, posttransplantation complications, and inpatient procedures were compared between patients with and without PC. Multivariate logistic regression was performed to identify predictors associated with PC use.

RESULTS

Among 21 458 patients undergoing HSCT during hospitalization, 278 (1.30%) received PC. The rate of PC use has significantly increased from 0.64% in 2008 to 1.95% in 2014. Patients receiving PC had more co-comorbidities, posttransplantation complications, inpatient procedures, and were more likely to carry a diagnosis of leukemia. In allogeneic HSCT, large bed size (odds ratio [OR] =2.80; 95% confidence interval [CI]: 1.17-6.70), stem cell source from cord blood (OR = 1.93; 95% CI: 1.15-3.24), and graft-versus-host disease (OR = 2.04; 95% CI: 1.36-3.06) were predictors of PC use. In a subset analysis of 783 patients who died during hospitalization, 166 (21.20%) received PC. Among the decedents, Hispanic race had lower odds of PC use (OR = 0.20; 95% CI: 0.05-0.82) in allogeneic HSCT and women had higher odds of PC (OR = 2.70; 95% CI: 1.35-5.41) in autologous HSCT.

CONCLUSIONS

The rate of PC use has significantly increased among patients undergoing HSCT during hospitalization from 2008 to 2014 but still remains very low. Further investigation is warranted to verify and better understand the barriers toward PC use for HSCT patients.

Safety and efficacy of rituximab-based first line treatment of chronic GVHD

Initial therapy of chronic GVHD (cGvHD) has not changed for over three decades, despite limited efficacy and long-term toxicity. We have previously shown in a small pilot study the feasibility of rituximab-based first-line therapy of cGVHD. To better assess safety and efficacy, we now evaluate 69 patients that received rituximab as part of their initial treatment. Median follow-up for surviving patients was 47 (11-81) months. Resolution of cGVHD occurred in 49 patients with median time to IST discontinuation of 349 (138-920) days. The cumulative incidence (CI) of cGHVD resolution was 41%, 69 and 77% at 1-, 2- and 3-years, respectively. No systemic corticosteroids were used in 27 patients, and 67% received ≤ 10 mg/kg cumulative exposure. Overall survival (OS) at 1-, 2- and 3-years following cGVHD diagnosis was 87, 79 and 77% respectively; corresponding rates of non-relapse mortality (NRM) were 10%, 16 and 19%. The probability of being alive and free of cGVHD at 1-, 2-, and 3-years was 36, 55, and 57% respectively. This study demonstrates the feasibility and efficacy of rituximab-based first-line cGVHD treatment. This approach demonstrates significant activity and avoids long courses of corticosteroids in most patients.

The Association of Performance Status and Disease Severity in Patients With Chronic Graft-vs-Host Disease

OBJECTIVE

Determine the relationship between functional status and degree of specific organ involvement, physical performance, and subjective well-being chronic graft-vs-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation.

DESIGN

Observational cohort.

SETTING

Outpatient clinic.

PARTICIPANTS

Adult patients (N=121) with cGVHD with 634 assessments.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Karnofsky Performance Status (KPS). Skin, fascia/joints, lungs, upper and lower extremity range of motion, liver, eye, mucosal, and gastrointestinal involvement were measured using the National Institutes of Health GVHD scale. Physical performance was assessed with the 2-minute walk test (2MWT) and hand grip strength. Subjective measures were the Patient Health Questionnaire 9 (PHQ-9) and Lee Symptom Burden (LSB) scale.

RESULTS

Myofascial (P<.001) and lung (P=.001) involvement, 2MWT (P<.001), LSB (P<.001), and PHQ-9 (P=.03) had the largest associations with KPS with liver (P=.05) and hand grip strength (P<.001) more modest associations with KPS.

CONCLUSIONS

Patients with cGVHD experience multifactorial impairment in function associated with potentially modifiable symptoms physiatrists have the expertise to address to enhance function. More research is needed to determine rehabilitation interventions to mitigate the impact of cGVHD on function.

CD34+ Cell Selection versus Reduced-Intensity Conditioning and Unmodified Grafts for Allogeneic Hematopoietic Cell Transplantation in Patients Age >50 Years with Acute Myelogenous Leukemia and Myelodysplastic Syndrome

Reduced-intensity conditioning (RIC) and T cell depletion (TCD) through CD34+ cell selection without the use of post-transplantation immunosuppression are 2 strategies used to reduce nonrelapse mortality (NRM) in older patients after allogeneic hematopoietic cell transplantation (allo-HCT). To compare the efficacy of the RIC and TCD approaches, we evaluated the outcomes of patients age >50 years with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) who underwent allo-HCT from an HLA-matched donor with one of these strategies. Baseline characteristics were comparable in the patients receiving TCD (n = 204) and those receiving RIC (n = 151), except for a higher proportion of unrelated donors (68% versus 40%; P < .001) and a higher comorbidity burden (Hematopoietic Cell Transplantation Comorbidity Index [HCT-CI] ≥3: 51% versus 38%; P < .001) in the TCD cohort. Analysis of outcomes at 3 years showed a higher chronic graft-versus-host disease (GVHD)/relapse-free survival (CRFS) (51% versus 7%; P < .001), lower incidences of grade II-IV acute GVHD (18% versus 46% at day +180) and chronic GVHD (6% versus 55% at 3 years; P < .001), and a lower incidence of relapse (19% versus 33% at 3 years; P = .001) in the TCD group compared with the RIC group. Relapse-free survival (RFS), overall survival (OS), and NRM were similar in the 2 groups. Combining transplantation approach (RIC versus TCD) and comorbidity burden (HCT-CI 0-2 versus ≥3), patients with an HCT-CI score of 0-2 seemed to benefit from the TCD approach. In conclusion, in this retrospective study, the use of a CD34+ cell-selected graft and a myeloablative conditioning regimen was associated with higher CRFS and similar RFS and OS compared with unmodified allo-RIC in patients age >50 years with AML and MDS.

HLA-inferred extended haplotype disparity level is more relevant than the level of HLA mismatch alone for the patients survival and GvHD in T cell-replate hematopoietic stem cell transplantation from unrelated donor

Serious risks in unrelated hematopoietic stem cell transplantation (HSCT) including graft versus host disease (GvHD) and mortality are associated with HLA disparity between donor and recipient. The increased risks might be dependent on disparity in not-routinely-tested multiple polymorphisms in genetically dense MHC region, being organized in combinations of two extended MHC haplotypes (Ehp). We assessed the clinical role of donor-recipient Ehp disparity levels in N = 889 patients by the population-based detection of HLA allele phase mismatch. We found increased GvHD incidences and mortality rates with increasing Ehp mismatch level even with the same HLA mismatch level. In multivariate analysis HLA mismatch levels were excluded from models and Ehp disparity level remained independent prognostic factor for high grade acute GvHD (p = 0.000037, HR = 10.68, 95%CI 5.50-32.5) and extended chronic GvHD (p < 0.000001, HR = 15.51, CI95% 5.36-44.8). In group with single HLA mismatch, patients with double Ehp disparity had worse 5-year overall survival (45% vs. 56%, p = 0.00065, HR = 4.05, CI95% 1.69-9.71) and non-relapse mortality (40% vs. 31%, p = 0.00037, HR = 5.63, CI95% 2.04-15.5) than patients with single Ehp disparity. We conclude that Ehp-linked factors contribute to the high morbidity and mortality in recipients given HLA-mismatched unrelated transplant and Ehp matching should be considered in clinical HSCT.

Outcomes of strategic alternative donor selection or suspending donor search based on Japan Marrow Donor Program coordination status

In allogeneic hematopoietic stem cell transplantation (allo-HSCT) from unrelated donors, delays in donor search are adversely associated with patient outcome. However, the optimal duration for either waiting for an unrelated donor or selecting alternative sources remains undetermined. Using data from the Japan Marrow Donor Program (JMDP) registry, we retrospectively analyzed 349 adult patients who had searched for unrelated donors. Two hundred and three patients received allo-HSCT from JMDP donors (Group A) with a median of 140 days required to identify a donor, 60 received allo-HSCT from alternative sources (Group B) after a median of 111.5 days at which point either all donor candidates had failed or the patient achieved a second or subsequent complete remission, and 77 suspended allo-HSCT (Group C) after a median of 310 days. The 5-year overall survival (OS) rate in Group A was superior to that of Group C (48.6 vs 38.5%, P = 0.001). Although Group B included more patients with high or very high disease risk index (DRI) at the time of allo-HSCT compared with Group A, the 5-year OS was not significantly different between Groups A and B (48.6 vs 40.9%, P = 0.07), indicating that switching to alternative donors may benefit patients with high DRI.

Sleep disruption among cancer patients following autologous hematopoietic cell transplantation

Despite a high prevalence of sleep disruption among hematopoietic cell transplant (HCT) recipients, relatively little research has investigated its relationships with modifiable cognitive or behavioral factors or used actigraphy to characterize sleep disruption in this population. Autologous HCT recipients who were 6 to 18 months post-transplant completed self-report measures of cancer-related distress, fear of cancer recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors upon enrollment. Patients then wore an actigraph for seven days and completed a self-report measure of sleep disruption on day seven of the study. Among the 84 participants (age M=60, 45% female), 41% reported clinically-relevant sleep disruption. Examination of actigraph data confirmed that, on average, sleep was disrupted (wake after sleep onset M=66 minutes) and sleep efficiency was less than recommended (sleep efficiency M=78%). Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors were related to self-reported sleep disruption (p’s < .05) but not objective sleep indices. Results suggest that many HCT recipients experience sleep disruption after transplant. Cancer-related distress, fear of recurrence, dysfunctional sleep cognitions, and maladaptive sleep behaviors are related to self-reported sleep disruption and should be considered targets for cognitive behavioral intervention in this population.

Frailty: the missing piece of the pre- hematopoietic cell transplantation assessment?

Hematopoietic stem cell transplantation (HSCT) represents a curative option for those afflicted with numerous hematologic malignancies and bone marrow failure syndromes. Advances and refinement of the HSCT process have resulted in increasing number of transplants performed on older patients in the recent years. Pre-transplant assessments (PTA) function to risk stratify patients prior to undergoing HSCT in an effort to predict those at higher risk of treatment-related toxicity, to inform risk/benefit assessments and to aid clinical decision making. Traditionally used risk stratification parameters such as chronologic age, comorbidity and performance status may not fully capture physical function, physiologic fitness, highlighting a need for improvement in PTA. Incorporation of frailty measurements in pre-HSCT assessments, particularly in elderly transplant candidates, may result in improving predictive ability of existing tools such as the Hematopoietic Cell Transplantation Comorbidity Index and Karnofsky performance status. Here, we review existing pre-HSCT assessment tools, measures of frailty that may aid in risk stratification for patients undergoing HSCT and directions for future research using frailty in the pre-HSCT setting.

Impact of Thymoglobulin by Stem Cell Source (Peripheral Blood Stem Cell or Bone Marrow) After Myeloablative Stem Cell Transplantation From HLA 10/10-Matched Unrelated Donors: A Report From the Société Française de Greffe de Moelle et de Thérapie Cellulaire

BACKGROUND

The impact of antithymocyte globulin (ATG) in the setting of a myeloablative conditioning transplantation remains controversial, especially when using bone marrow (BM) as the stem cell source.

METHODS

We therefore conducted a retrospective analysis to investigate the impact of ATG in patients with acute myeloid leukemia or myelodysplastic syndrome receiving myeloablative conditioning followed by a matched 10 of 10 unrelated donor transplant from BM or peripheral blood stem cells (PBSCs). Our study included 356 patients conditioned with cyclophosphamide associated with fractionated total body irradiation or busulfan.

RESULTS

Median follow-up was 17.6 months (range, 0-156). The ATG and PBSCs were the only variables that independently decreased the cumulative incidence (CI) of chronic graft-versus-host disease (GvHD) (hazards ratio [HR], 0.4; 95% CI, 0.21-0.73; P < 0.01; and HR, 0.53; 95% CI, 0.30-0.90; P = 0.02, respectively). The ATG had no impact on overall survival, disease-free survival, relapse, and nonrelapse mortality. In the PBSC group (n = 139), ATG was associated with a lower CI of both grades III to IV acute GvHD (HR, 0.17; 95% CI, 0.03-0.91; P = 0.04), chronic GvHD (HR, 0.31; 95% CI, 0.11-0.87; P = 0.03), and GvHD-free/relapse-free survival (HR, 0.48; 95% CI, 0.29-0.80; P < 0.01), whereas these correlations were not significant in the group of patients (n = 217) receiving BM (HR, 0.36; 95% CI, 0.11-1.93; P = 0.06 for grade III-IV acute GvHD; HR, 0.49; 95% CI, 0.22-1.06; P = 0.08 for chronic GvHD; and HR, 0.69; 95% CI, 0.46-1.01; P = 0.06 for GvHD-free/relapse-free survival).

CONCLUSIONS

Although our results confirm the recommendation for ATG to be added after PBSC transplantation, no obvious benefit was identified using this approach in the setting of BM transplantation. Only prospective studies may yield definitive answers to this question.

Perception of late effects among long-term survivors after haematopoietic stem cell transplantation: Descriptive analysis and validation of the Brief Illness Perception Questionnaire. A sub-study of the PROVIVO study

PURPOSE

To give a first description of the perception of late effects among long-term survivors after Allogeneic Haematopoietic Stem Cell Transplantation (HSCT) and to validate the German Brief Illness Perception Questionnaire (BIPQ).

METHODS

This is a secondary analysis of data from the cross-sectional, mixed-method PROVIVO study, which included 376 survivors from two Swiss HSCT-centres. First, we analysed the sample characteristics and the distribution for each BIPQ item. Secondly, we tested three validity types following the American Educational Research Association (AERA)Standards: content validity indices (CVIs) were assessed based on an expert survey (n = 9). A confirmatory factor analysis (CFA) explored the internal structure, and correlations tested the validity in relations to other variables including data from the Hospital Anxiety and Depression Scale (HADS), the number and burden of late effects and clinical variables.

RESULTS

In total, 319 HSCT recipients returned completed BIPQs. For this sample, the most feared threat for post-transplant life was long lasting late effects (median = 8/10). The expert-survey revealed an overall acceptable CVI (0.82), three items-on personal control, treatment control and causal representation-yielded low CVIs (<.78). The CFA confirmed that the BIPQ fits the underlying construct, the Common-Sense Model (CSM) (χ² (df) = 956.321, p = 0.00). The HADS-scores correlated strongly with the item emotional representation (r = 0.648; r = 0.656).

CONCLUSION

According to its overall content validity, the German BIPQ is a promising instrument to gain deeper insights into patients' perceptions of HSCT late effects. However, as three items revealed potential problems, improvements and adaptions in translation are therefore required. Following these revisions, validity evidence should be re-examined through an in-depth patient survey.

An Open-Label Phase II Randomized Trial of Topical Dexamethasone and Tacrolimus Solutions for the Treatment of Oral Chronic Graft-versus-Host Disease

The objective of this study was to evaluate the safety and efficacy of single-agent dexamethasone or tacrolimus topical solution as first-line treatment for symptomatic oral chronic graft-versus-host disease (cGVHD). This was a prospective, single-center, open-label, randomized phase II trial of patients with symptomatic oral cGVHD without prior topical therapy. Subjects were randomly assigned 1:1 to either topical dexamethasone (.5 mg/mL) or tacrolimus (.5 mg/mL) solution and instructed to rinse with 5 mL for 5 minutes, 4 times a day, for 4 weeks. Oral cGVHD assessments (National Institutes of Health [NIH] criteria) were completed at baseline and end of treatment (NIH criteria, global response, and tolerability). The primary endpoint was the response rate defined as ≥3-point reduction in patient-reported sensitivity score (range, 0 to 10). A parallel 2-stage design was employed so that a less efficacious arm could be terminated early. The accrual goal was 60 evaluable patients; 30 in each arm), accruing 14 in the first stage and 16 in the second stage. If both arms were regarded as efficacious, a "pick-the-winner" method would be employed to choose a better treatment for future investigation. Forty-six subjects were randomized to receive either dexamethasone (n = 28) or tacrolimus (n = 18). Six subjects were excluded from the analysis because of changes in systemic immunosuppression (dexamethasone  = 1, tacrolimus  = 3) or lack of end-of-treatment visit (1 per arm). After the first stage evaluation, the tacrolimus arm was terminated because of lack of activity (3 of 14 responses; response rate, 21%). Twenty-six subjects in the dexamethasone arm completed both study visits and were included in the response analysis, with a 58% (15 of 26) response rate, compared with 21% (3 of 14) in the tacrolimus arm (P = .05). The response rates according to the NIH score in the dexamethasone and tacrolimus arms were 50% (13 of 26) and 2% (2 of 14), respectively (P = .04). From the onset of therapy, 31% versus 21% patients reported feeling "much better" and 38% versus 36% reported feeling "slightly better," giving an overall global response rate ("much better" or "slightly better") of 81% (21 of 26) versus 71% (10 of 14), in the dexamethasone and tacrolimus arms, respectively. Dexamethasone rinses were well tolerated and taste was reported as "very pleasant" or "tolerable" in most subjects (96%). Intensive topical therapy with dexamethasone solution is effective for managing patients with new-onset symptomatic oral cGVHD and should be considered for first-line therapy. Topical tacrolimus solution appears less effective, at least for first-line therapy.

The Value of Patient Reported Outcomes and Other Patient-Generated Health Data in Clinical Hematology

With cures and long-term survival rates increasing in hematologic malignancies, increased focus has been placed on gaining a better understanding of the patient experience from disease and treatment effects. This has been the basis for the utilization of patient reported outcomes (PRO) and other patient-generated health data (PGHD) in efforts to improve long-term health-related quality of life (HRQOL). This review will summarize the impact PROs have had on the evolving standard of care for patients with hematologic malignant conditions and will conclude with a template for the integration of PRO and PGHD to enhance the patient experience, using stem cell transplantation as an example.

Risk factors for depression and fatigue among survivors of hematopoietic cell transplantation

BACKGROUND

Patients treated with hematopoietic cell transplantation (HCT) often experience depression and fatigue but analyses to determine risk factors have typically lacked statistical power. The current study examined sociodemographic and clinical risk factors for depression and fatigue in a large cohort of survivors of HCT.

METHODS

Measures of depression and fatigue were included in an annual survey of HCT recipients that also included self-reported sociodemographic and health information. Patient clinical characteristics were obtained from the clinical database.

RESULTS

The sample consisted of 1869 recipients (with a mean age of 56 years; 53% male) who were a mean of 13 years (allogeneic recipients) and 6 years (autologous recipients) from HCT. Moderate to severe depression was reported by 13% of participants; moderate to severe fatigue was reported by 42%. Among allogeneic recipients, female sex, younger age, current presence of chronic pain, and current patient-reported severity of chronic graft-versus-host disease were found to be independently associated with greater depression whereas female sex, current presence of chronic pain, and current severity of chronic graft-versus-host disease were independently associated with greater fatigue (P values <.01). Among autologous recipients, younger age and current presence of chronic pain were found to be independently associated with both greater depression and greater fatigue (P values <.01).

CONCLUSIONS

Rates of depression and fatigue in this group of survivors suggest a high symptom burden. Better screening, referral, and interventions are needed.

Prevalence of ocular hypertension and glaucoma in patients with chronic ocular graft-versus-host disease

PURPOSE

To evaluate the prevalence of ocular hypertension (OHT) and glaucoma in patients with chronic ocular graft-versus-host disease (GVHD).

METHODS

We performed a retrospective chart review of 218 patients diagnosed with chronic ocular GVHD. Ocular hypertension was defined as intraocular pressure (IOP) ≥ 24 mmHg in either eye without any glaucomatous optic disc changes. Glaucoma suspect was defined as optic disc changes with a cup-to-disc ratio ≥ 0.7 in either eye or asymmetry of ≥ 0.3 between the two eyes. Glaucoma was defined by glaucomatous optic disc changes plus glaucomatous visual field defects in two consecutive reliable visual field tests. The number of cases of ocular hypertension, glaucoma, and glaucoma suspects was evaluated.

RESULTS

Thirty-three patients (15 %) were diagnosed with OHT, eight patients (3.6 %) with suspicion of glaucoma, and one patient (0.4 %) with glaucoma. OHT occurred within 6 months of developing ocular GVHD in 60 % of the cases and within the first year in 76 %. High IOP normalized in 67 % of patients when the dosage of topical or systemic corticosteroids was lowered, and 27 % of patients required anti-glaucoma therapy.

CONCLUSIONS

Ocular hypertension is a common complication in patients with ocular GVHD, with a prevalence of 15 %. The rise in intraocular pressure is often transient and resolves with management of corticosteroids in most cases. However, clinicians should be aware that nearly one-third of the patients with OHT might require anti-glaucoma treatment. The prevalences of glaucoma and suspicion of glaucoma were not higher than in the general population.

Prevalence and determinants of fatigue in patients with moderate to severe chronic GvHD

Although fatigue is common after allogeneic hematopoietic cell transplantation, little is known about fatigue in patients with chronic GvHD (cGvHD). The aim of this study was to explore factors associated with fatigue in cGvHD. Data were drawn from a sequentially recruited, cross-sectional study of adults with moderate or severe cGvHD (n=263). Respondents were classified as fatigued or not fatigued based on their response to a single item regarding loss of energy from the Lee cGvHD Symptom Scale. In univariate analysis, factors significantly associated with fatigue included performance status, number of prior cGvHD therapies, cGvHD symptom bother, self-assessed physical and mental health, nutritional status, walk velocity and self-reported physical activity. There were no significant associations between fatigue and disease-related cGvHD variables. Multivariable logistic regression demonstrated that being less active and having pulmonary and/or muscle/joint symptoms were independently associated with fatigue. In conclusion, clinically significant fatigue was prevalent in more than one-third of subjects with cGvHD, and was disabling. Absence of association with measures of cGvHD severity underscores the need to elucidate the pathogenesis of fatigue and its relationship with inflammatory activity. Pulmonary and muscle/joint symptoms and physical inactivity represent potential targets for intervention in clinical studies.

What They Want: Inclusion of Blood and Marrow Transplantation Survivor Preference in the Development of Models of Care for Long-Term Health in Sydney, Australia

Four hundred forty-one adult allogeneic blood and marrow transplantation (BMT) survivors participated in a cross-sectional survey to assess long-term follow-up (LTFU) model of care preference. Survey instruments included the Sydney Post BMT Survey, Functional Assessment of Cancer Therapy-BMT, Depression Anxiety Stress Scales 21, the Chronic GVHD Activity Assessment-Patient Self Report (Form B), the Lee Chronic GVHD Symptom Scale and the Post-Traumatic Growth Inventory. We found most BMT survivors (74%) would prefer LTFU with their transplantation physicians alone or in combination with transplantation center-linked services (satellite clinics or telemedicine) Over one-quarter indicated a preference for receiving comprehensive post-transplantation care in a "satellite" clinic staffed by their BMT team situated closer to their place of residence, with higher income, higher educational level, and sexual morbidity being significant social factors influencing this preference. Regular exercise was reported less often in those who preferred telemedicine, which may reflect reduced mobility. The factor most strongly associated with a preference for transplantation center follow-up was the severity of chronic graft-versus-host disease. Full- and part-time work were negatively associated with transplantation center follow-up, possibly implying decreased dependency on the center and some return to normalcy. This study is the first to explore the preferences of BMT survivors for long-term post-transplantation care. These data provides the basis for LTFU model of care development and health service reform consistent with the preferences of BMT survivors.

Psychometric analysis of the Korean version of the high-dose chemotherapy specific quality of life questionnaire module from the European Organization for Research and Treatment of Cancer (EORTC QLQ-HDC29)

PURPOSE

We evaluated the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer high-dose chemotherapy specific quality of life questionnaire module (EORTC QLQ-HDC29) when implemented with Korean patients by conducting a multicenter, longitudinal study in three Korean hospitals.

METHODS

A total of 226 patients who scheduled to receive the HDC followed by hematopoietic stem cell transplantation (HSCT) were enrolled. The patients were asked to complete three questionnaires [the EORTC Core Questionnaire (QLQ-C30), QLQ-HDC29, and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation] at four points in time: before HSCT and 100, 180, and 365 days after HSCT. Standard validity and reliability analyses were performed.

RESULTS

Internal consistency of the QLQ-HDC29 was generally acceptable, as tested by Cronbach's α, except for the scales body image and the inpatient issues. Cronbach's α values for the Korean version of the QLQ-HDC29 were almost in accordance with results of the original version, except for the scales body image (lower to the original QLQ-HDC29, α = 0.73) and impact on family (higher to the original QLQ-HDC29, α = 0.52). Known-group comparison analyses showed significantly higher symptom burdens in patients with poor performance status or graft versus host disease (similar to the original QLQ-HDC29). The QLQ-HDC29 indicated good convergent and discriminant validity and showed responsiveness to changes in line with a clinical course over time after HSCT.

CONCLUSIONS

The QLQ-HDC29 is generally reliable and adequate to assess QoL in Korean patients undergoing HDC followed by HSCT.

Parent Outlook: How Parents View the Road Ahead as They Embark on Hematopoietic Stem Cell Transplantation for Their Child

Pediatric hematopoietic stem cell transplantation (HSCT) offers cure for high-risk malignancies and other conditions, but carries a risk of complications. Parental outlook regarding their child's transplantation course and future health has been largely unexplored. This report presents the Parent Outlook Scale, describes its properties, and examines the outlook of parents embarking on their child's transplantation course and the associated variables. Parents of children scheduled to undergo HSCT (n = 363) at 8 US transplantation centers completed the Parent Outlook Scale, comprising 4 items assessing frequency of the parent's thoughts about the potential difficulty of the child's transplantation (Transplant Difficult subscale) and worsened health (Health Worse subscale). Item responses were rated on a 5-point Likert scale (ranging from "none" to "all of the time") and, along with scale/subscale scores, transformed to 100-point scales, with higher scores connoting greater thought frequency. Psychometrics were explored. Multivariable models identified personal and clinical characteristics associated with scale and subscale scores. The Parent Outlook Scale (α = 0.75) and subscales were found to have sound psychometric properties. Factor loading supported the single scale with 2 subscales representing distinct aspects of overall outlook. Mean scores (Parent Outlook, 52.5 ± 21.7; Transplant Difficult, 64.4 ± 25.6; Health Worse, 40.7 ± 25.7) revealed variability within and across scale/subscales. Significantly different mean subscale scores (P < .001) indicated more frequent Transplant Difficult thoughts than Health Worse thoughts. Clinical factors (solid tumor diagnosis and unrelated donor transplant) and a parent factor (worse emotional functioning) were associated with higher scale and subscale scores. Our findings show that the outlook of parents embarking on their child's HSCT course is varied and not solely a product of clinical factors readily apparent to clinicians. Referring and transplantation clinicians should create opportunities to explore with parents their perspectives and concerns before and during the course of HSCT.

Assessing the relationship between oral chronic graft-versus-host disease and global measures of quality of life

OBJECTIVE

Chronic GVHD (cGVHD) is a frequent complication of allogeneic hematopoietic stem cell transplantation (HSCT) and affects multiple organ systems, with the oral cavity being one of the most frequently affected sites. Patients with cGVHD experience reduced quality of life (QOL), yet the specific impact of oral cGVHD on QOL is poorly understood. The objective of this study was to characterize the impact of oral cGVHD on global measures of QOL.

MATERIALS AND METHODS

QOL data were collected using the FACT-BMT and SF-36 instruments for 569 patients enrolled in the Chronic GVHD Consortium, with a total of 1915 follow-up visits. At study enrollment, patients were categorized as isolated oral cGVHD (n=22), oral and concomitant extra-oral cGVHD (n=420), and only extra-oral cGVHD (n=127). Utilizing all longitudinal data, QOL scores were compared using a multivariable linear model controlling for demographic, transplant, and cGVHD characteristics.

RESULTS

Patients with isolated oral cGVHD reported better physical well-being (P=0.009), BMT well-being (P=0.01), and decreased bodily pain (P=0.01) compared to patients with oral and concomitant extra-oral cGVHD, but the differences in scores did not reach the defined threshold for clinical significance (6 points for FACT-BMT domains and 5 points for SF-36 domains).

CONCLUSIONS

Global QOL scores are similar in patients with isolated oral cGVHD and patients with oral and concomitant extra-oral cGVHD.

A Pound of Cure Requires An Ounce (or More) of Prevention: Survivorship and Complications of Therapy for Hematologic Malignancies

Patients treated for a hematologic malignancy are at risk for treatment-related complications. As the goal of therapy is frequently curative, treatments are especially intensive and long-term toxicity is common. Chemotherapy and radiation are associated with increased risk for cardiac and pulmonary disease, endocrine disorders, infertility, sexual dysfunction, second cancers, and psychosocial distress. The risk for each complication is dictated by patient characteristics including age, co-morbidities, and genetic predispositions, as well as the specifics of therapy. Survivors of pediatric cancers and allogeneic hematopoietic stem cell transplantation have unique risks due to vulnerable age at time of toxic exposure and ongoing immune dysfunction, respectively.

Impact of outpatient non-myeloablative haematopoietic stem cell transplantation in quality of life vs. conventional therapy

The role of outpatient hematopoietic stem cell transplantation (HSCT) as a therapeutic tool has been strengthened significantly because of the increasing number of patients undergoing this treatment. Due the very nature of this procedure, one of the aspects that should not be overlooked is the quality of life (QOL) of patients undergoing HSCT. Thus, one must consider not only health status after treatment, but also, the psychosocial implications for the patient. This is an observational, longitudinal, and prospective study to assess QOL in patients undergoing outpatient HSCT vs. similar patients receiving medical treatment (MxTx). By applying the COOP/WONKA charts on five occasions (pre-HSCT/initial, post-HSCT/first month, and at 3, 6, and 9 months), thirty-eight patients were analysed, 19 with HSCT and 19 with MxTx with no differences in age, gender or diagnosis. The initial survey found significant differences only in pain perception, which was higher in the HSCT group (p = .08); at the first month, there was a greater tendency for feelings of depression or anxiety in the HSCT group (p = .016), with more limitations in social (p = .003) and daily (p = .044) activities. From 3 months post-HSCT, the results were very similar. The differences persisted only in the area of social activities. Four patients developed graft-versus-host disease with no significant difference in the scores obtained compared to other transplant patients at 3, 6, and 9 months (p = .26) of follow-up.

Impact of Ocular Chronic Graft-versus-Host Disease on Quality of Life

Ocular involvement can be quite symptomatic in patients with chronic graft-versus-host disease (GVHD). The prevalence of and risk factors for ocular GVHD and its impact on quality of life (QOL) in patients with chronic GVHD were studied in a prospective, multicenter, longitudinal, observational study. This study enrolled 342 patients with 1483 follow-up visits after allogeneic hematopoietic cell transplantation. All patients in this analysis were diagnosed with chronic GVHD requiring systemic treatment and enrolled within 3 months of chronic GVHD diagnosis. The symptom burden of ocular GVHD was based on the degree of dry eye symptoms, frequency of artificial tear usage, and impact on activities of daily living. Patients' QOL was measured by self-administered questionnaires. Variables associated with ocular GVHD at enrollment and subsequent new-onset ocular GVHD and the associations with QOL were studied. Of the 284 chronic GVHD patients, 116 (41%) had ocular GVHD within 3 months of chronic GVHD diagnosis ("early ocular GVHD"). Late ocular GVHD (new onset > 3 months after chronic GVHD diagnosis) occurred in 64 patients. Overall cumulative incidence at 2 years was 57%. Female gender (P = .005), higher acute GVHD grade (P = .04), and higher prednisone dose at study entry (P = .04) were associated with early ocular GVHD. For patients who did not have ocular GVHD within 3 months of chronic GVHD diagnosis, presence of prior grades I to IV acute GVHD (HR 1.78, P = .04) was associated with shorter time to late ocular GVHD, whereas female donor-male recipient (HR .53, P = .05) was associated with longer time to late ocular GVHD onset. Using all visit data, patients with ocular GVHD had worse QOL, as measured by Functional Assessment of Cancer Therapy Bone Marrow Transplantation (P = .002), and greater chronic GVHD symptom burden, as measured by the Lee symptom overall score excluding the eye component (P < .001), compared with patients without ocular GVHD. In conclusion, this large, multicenter, prospective study shows that ocular GVHD affects 57% of patients within 2 years of chronic GVHD diagnosis. Women, patients on higher doses of prednisone at study entry, and those with a history of acute GVHD were at higher risk for ocular GVHD. Strong evidence suggests that ocular GVHD is associated with worse overall health-related QOL.

Vision-Related Quality of Life in Patients with Ocular Graft-versus-Host Disease

PURPOSE

To assess the vision-related quality of life (QOL) in a cohort of patients with ocular graft-versus-host disease (GVHD).

DESIGN

Prospective study.

PARTICIPANTS

Eighty-four patients diagnosed with chronic ocular GVHD.

METHODS

We assessed the vision-related QOL with the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). The symptoms of ocular GVHD were assessed using the Ocular Surface Disease Index (OSDI) and Symptom Assessment in Dry Eye (SANDE) questionnaires.

MAIN OUTCOME MEASURES

We assessed vision-related QOL with the NEI-VFQ-25 and compared the scores obtained from patients with ocular GVHD with those from a healthy population. In the ocular GVHD population, we also evaluated the associations between the NEI-VFQ-25 and the dry eye symptoms measured by the OSDI and SANDE questionnaires, age, duration of disease, best-corrected visual acuity (BCVA), corneal fluorescein staining (CFS), tear break-up time, and Schirmer test.

RESULTS

The mean composite NEI-VFQ-25 score in patients with ocular GVHD was 76.5±17. Compared with healthy subjects, patients with ocular GVHD reported reduced scores on all NEI-VFQ-25 subscales (each P < 0.001) with the exception of color vision (P = 0.11). The NEI-VFQ-25 composite scores significantly correlated with OSDI (R = -0.81, P < 0.001), SANDE (R = -0.56, P < 0.001), CFS (R = -0.36, P = 0.001), and BCVA (R = -0.30, P = 0.004).

CONCLUSIONS

Patients with ocular GVHD experience measurable impairment of vision-related QOL. This study highlights the impact of ocular GVHD on the vision-related QOL, and thus the importance of comprehensive diagnosis and treatment of this condition.

National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease: V. The 2014 Ancillary Therapy and Supportive Care Working Group Report

The 2006 National Institutes of Health (NIH) Consensus paper presented recommendations by the Ancillary Therapy and Supportive Care Working Group to support clinical research trials in chronic graft-versus-host disease (GVHD). Topics covered in that inaugural effort included the prevention and management of infections and common complications of chronic GVHD, as well as recommendations for patient education and appropriate follow-up. Given the new literature that has emerged during the past 8 years, we made further organ-specific refinements to these guidelines. Minimum frequencies are suggested for monitoring key parameters relevant to chronic GVHD during systemic immunosuppressive therapy and, thereafter, referral to existing late effects consensus guidelines is advised. Using the framework of the prior consensus, the 2014 NIH recommendations are organized by organ or other relevant systems and graded according to the strength and quality of supporting evidence.

Outcomes of phacoemulsification in patients with chronic ocular graft-versus-host disease

PURPOSE

The purpose of this study was to evaluate the outcomes of phacoemulsification in patients with ocular graft-versus-host disease (GVHD).

METHODS

The occurrence of cataracts, cataract surgery, and its outcomes were analyzed in the medical records of 229 patients (458 eyes) with ocular GVHD. Outcome measures included pre- and postoperative corrected distance visual acuity (CDVA) and the rate of postoperative complications.

RESULTS

Of the 458 eyes evaluated, 58 were pseudophakic; from the 400 phakic eyes, 238 (59 %) presented with cataracts and 62 (26 %) underwent cataract surgery. Analysis of postoperative complications and visual outcomes at 1 month was performed in 51 eyes in which detailed surgical and immediate postoperative records were available. Preoperatively, the mean CDVA was 0.67 ± 0.57 LogMAR (Snellen 20/93), improving postoperatively to 0.17 ± 0.18 (Snellen 20/29) at 1 month (P < 0.0001), and to 0.13 ± 0.14 (Snellen 20/26) by the final follow-up visit (P < 0.0001). Postoperative complications included corneal epithelial defects (8 %), filamentary keratitis (6 %), worsening of corneal epitheliopathy (16 %), posterior capsular opacification (18 %), and cystoid macular edema (4 %). A corrected distance visual acuity of 20/30 or better was achieved in 87 % of the eyes; suboptimal CDVA improvement was attributable to severe ocular surface disease, pre-existing advanced glaucoma, and prior macular surgery.

CONCLUSIONS

Phacoemulsification in patients with chronic ocular GVHD is a safe and efficacious procedure resulting in significant visual improvement. Overall, postoperative adverse events responded well to timely management.

Health-related quality of life in patients who develop bronchiolitis obliterans syndrome following allo-SCT

Bronchiolitis obliterans syndrome (BOS) remains an important complication following allo-SCT. The development of this condition portends a higher morbidity and mortality but the effect on heath-related quality of life (HRQL) is unknown. The aim of this study was to determine whether the development of BOS impacted HRQL compared with patients without BOS. This Institutional Review Board-approved prospective study analyzed 126 patients who underwent allo-SCT at our institution. Patients were administered three HRQL survey tools (SF-36, European Organization for Research and Treatment of Cancer QLQ-c30 and St George Respiratory Questionnaire (SGRQ)) before transplant and then again at 6 months, 1 year and 2 years after transplant. Patients were analyzed in three groups determined by highest chronic GVHD (cGVHD) severity and BOS status. Overall, our study group had improving HRQL after transplant when measured over time, measured by the SF-36 with stable HRQL, when measured by the SGRQ total score and QLQ-c30. Patients that developed BOS had significantly worse HRQL scores measured by the SGRQ and the SF-36 physical composite score. This difference was not explained by the severity of cGVHD that patients with BOS developed.
