Integrating Palliative Care and Hematologic Malignancies: Bridging the Gaps for Our Patients and Their Caregivers

Patients with hematologic malignancies (HMs) struggle with immense physical and psychological symptom burden, which negatively affect their quality of life (QOL) throughout the continuum of illness. These patients are often faced with substantial prognostic uncertainty as they navigate their illness course, which further complicates their medical decision making, especially at the end of life (EOL). Consequently, patients with HM often endure intensive medical care at the EOL, including frequent hospitalization and intensive care unit admissions, and they often die in the hospital. Our EOL health care delivery models are not well suited to meet the unique needs of patients with HMs. Although studies have established the role of specialty palliative care for improving QOL and EOL outcomes in patients with solid tumors, numerous disease-, clinician-, and system-based barriers prevail, limiting the integration of palliative care for patients with HMs. Nonetheless, multiple studies have emerged over the past decade identifying the role of palliative care integration in patients with various HMs, resulting in improvements in patient-reported QOL, symptom burden, and psychological distress, as well as EOL care. Importantly, these studies have also identified active components of specialty palliative care interventions, including strategies to promote adaptive coping especially in the face of prognostic uncertainty. Future work can leverage the knowledge gained from specialty palliative care integration to develop and test primary palliative care interventions by training clinicians caring for patients with HMs to incorporate these strategies into their clinical practice.

Group Coping Intervention in Patients With Chronic Graft-Versus-Host Disease: A Pilot Randomized Clinical Trial

BACKGROUND

More than half the long-term survivors of allogeneic hematopoietic cell transplantation develop chronic graft-versus-host disease (GVHD), a debilitating inflammatory syndrome. Supportive interventions to assist survivors in coping with chronic GVHD are critically needed.

PATIENTS AND METHODS

We conducted a pilot randomized clinical trial of a multidisciplinary group intervention (Horizons Program; n=39) versus minimally enhanced usual care (n=41) for patients with moderate or severe chronic GVHD. Horizons participants received 8 weekly sessions about GVHD and coping co-led by a transplant clinician and a behavioral health expert via a secure videoconferencing platform. Participants completed the following surveys before randomization, at 10 weeks, and at 18 weeks: Functional Assessment of Cancer Therapy-Bone Marrow Transplant Scale (FACT-BMT) for quality of life (QoL), Lee Symptom Scale for symptom burden, and Hospital Anxiety and Depression Scale-Depression Symptoms (HADS) for mood. The primary endpoint was feasibility (≥50% enrollment, ≥80% attendance in half the sessions for the Horizons arm only, and ≥80% retention). We also explored preliminary efficacy of the Horizons intervention on changes in patient-reported outcomes with linear mixed effects models and estimates of effect size at 10 weeks.

RESULTS

We enrolled and registered 80 (67.2%) of 119 eligible patients (mean age, 62 years; 48.8% female). Of the participants in the Horizons Program, 84.6% attended at least half the sessions. Of registered participants, 91.3% completed assessment follow-ups (Horizons, 35/39 [89.7%]; minimally enhanced usual care, 38/41 [92.7%]). Horizons participants reported improvements in QoL (b = 2.24; d=0.53), anxiety symptoms (b = -0.10; d=0.34), and depression symptoms (b = -0.71; d=0.44) compared with participants who received minimally enhanced usual care.

CONCLUSIONS

Participation in a multidisciplinary group intervention study was feasible for patients with chronic GVHD, with promising signals for improving QoL and mood. A full-scale efficacy trial is needed to confirm effects on patient-reported outcomes.

Chronic graft-versus-host disease. Part I: Epidemiology, pathogenesis, and clinical manifestations

Chronic graft-versus-host disease is a major complication of allogeneic hematopoietic cell transplantation and a leading cause of long-term morbidity, nonrelapse mortality, and impaired health-related quality of life. The skin is commonly affected and presents heterogeneously, making the role of dermatologists critical in both diagnosis and treatment. In addition, new clinical classification and grading schemes inform treatment algorithms, which now include 3 U.S. Food and Drug Administration-approved therapies, and evolving transplant techniques are changing disease epidemiology. Part I reviews the epidemiology, pathogenesis, clinical manifestations, and diagnosis of chronic graft-versus-host disease. Part II discusses disease grading and therapeutic management.

Understanding and treatment of cutaneous graft-versus-host-disease

The skin is the outermost mechanical barrier where dynamic immune reactions take place and is the most commonly affected site in both acute and chronic graft-versus-host disease (GVHD). If not properly treated, pain and pruritis resulting from cutaneous GVHD can increase the risk of secondary infection due to erosions, ulcerations, and damage of underlying tissues. Furthermore, resulting disfiguration can cause distress and significantly impact patients' quality of life. Thus, a deeper understanding of skin-specific findings of GVHD is needed. This review will highlight some promising results of recent pre-clinical studies on the pathophysiology of skin GVHD and summarize the diagnostic and staging/grading procedures according to the clinical manifestations of skin GVHD. In addition, we will summarize outcomes of various GVHD treatments, including skin-specific response rates.

Understanding the Needs and Lived Experiences of Patients With Graft-Versus-Host Disease: Real-World European Public Social Media Listening Study

BACKGROUND

Graft-versus-host disease (GVHD) is the major cause of short- and long-term morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Treatment options beyond corticosteroid therapy remain limited, and prolonged treatment often leads to impaired quality of life (QoL). A better understanding of the needs and experiences of patients with GVHD is required to improve patient care.

OBJECTIVE

The aim of this study is to explore different social media (SM) channels for gathering and analyzing the needs and experiences of patients and other stakeholders across 14 European countries.

METHODS

We conducted a retrospective analysis of SM data from the public domain. The Talkwalker social analytics tool collected data from open-access forums, blogs, and various social networking sites using predefined search strings. The raw data set derived from the aggregator tool was automatically screened for the relevancy of posts, generating the curated data set that was manually reviewed to identify posts that fell within the predefined inclusion and exclusion criteria. This final data set was then used for the deep-dive analysis.

RESULTS

A total of 9016 posts relating to GVHD were identified between April 2019 and April 2021. Deduplication and relevancy checks resulted in 325 insightful posts, with Twitter contributing 250 (77%) posts; blogs, 49 (15%) posts; forums, 13 (4%) posts; Facebook, 7 (2%) posts; and Instagram and YouTube, 4 (1%) posts. Patients with GVHD were the primary stakeholders, contributing 63% of all SM posts. In 234 posts, treatment was the most discussed stage of the patient journey (68%), followed by symptoms (33%), and diagnosis and tests (21%). Among treatment-related posts (n=159), steroid therapy was most frequently reported (54/159, 34%). Posts relating to treatment features (n=110) identified efficacy (45/110, 41%), side effects (38/110, 35%), and frequency and dosage (32/110, 29%), as the most frequently discussed features. Symptoms associated with GVHD were described in 24% (77/325) of posts, including skin-related conditions (49/77, 64%), dry eyes or vision change (13/77, 17%), pain and cramps (16/77, 21%), and fatigue or muscle weakness (12/77, 16%). The impacts of GVHD on QoL were discussed in 51% (165/325) of all posts, with the emotional, physical and functional, social, and financial impacts mentioned in 69% (114/165), 50% (82/165), 5% (8/165), and 2% (3/165) of these posts, respectively. Unmet needs were reported by patients or caregivers in 24% (77/325) of analyzed conversations, with treatment-related side effects being the most common (35/77, 45%) among these posts.

CONCLUSIONS

SM listening is a useful tool to identify medical needs. Treatment of GVHD, including treatment-related side effects, as well as its emotional and physical impact on QoL, are the major topics that GVHD stakeholders mention on SM. We encourage a structured discussion of these topics in interactions between health care providers and patients with GVHD.

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.
