Exercise and inflammatory cytokine regulation among older adults with myeloid malignancies

Tumor necrosis factor (TNF)α is a major regulator of inflammation. However, the epigenetic regulation of TNFα in the context of an exercise intervention among older adults with cancer is understudied. In this exploratory analysis, we used data from a single-arm mobile health (mHealth) exercise intervention among older adults with myeloid malignancies to 1) assess changes in TNFα promoter methylation, TNFα mRNA expression, serum TNFα and other related-cytokine levels after intervention; and 2) assess correlations between blood markers and exercise levels. Twenty patients were included. From baseline to post-intervention, there was no statistical changes in TNFα promoter methylation status at seven CpG sites, TNFα mRNA expression, and serum TNFα levels. Effect sizes, however, were moderate to large for several CpG sites (-120, -147, -162, and -164; Cohen's d = 0.44-0.75). Median serum TNFα sR1 levels increased (83.63, IQR 130.58, p = 0.06; Cohen's d = 0.18) but not the other cytokines. Increases in average daily steps were correlated with increases in TNFα promoter methylation at CpG sites -147 (r = 0.48; p = 0.06) and -164 (r = 0.51; p = 0.04). Resistance training minutes were negatively correlated with TNFα promoter methylation at CpG site -120 (r = -0.62; p = 0.02). All effect sizes were moderate to large. In conclusion, after a mHealth exercise intervention, we demonstrated changes with moderate to large effect sizes in several CpG sites in the TNFα promoter region. Exercise levels were correlated with increases in TNFα promoter methylation. Larger exercise trials are needed to better evaluate TNFα regulation to inform interventions to augment TNFα regulation in order to improve outcomes in older adults with cancer.

Exercise and epigenetic ages in older adults with myeloid malignancies

BACKGROUND

Older adults with myeloid malignancies are susceptible to treatment-related toxicities. Accelerated DNAm age, or the difference between DNA methylation (DNAm) age and chronological age, may be used as a biomarker of biological age to predict individuals at risk. In addition, cancer treatment can also lead to accelerated DNAm age. Exercise is a promising intervention to reduce or prevent functional, psychological, and cognitive impairments in older patients with myeloid malignancies, yet there is little evidence of the effects of exercise on DNAm age. We explored (1) the associations of accelerated DNAm age with physical, psychological, and cognitive functions at baseline; (2) changes in DNAm age from baseline to post-intervention; and (3) the associations of changes in accelerated DNAm age with changes in functions from baseline to post-intervention.

METHODS

We enrolled older patients with myeloid malignancies to a single-arm pilot study testing a mobile health (mHealth) exercise intervention that combines an exercise program (EXCAP©®) with a mobile application over 2 cycles of chemotherapy (8-12 weeks). Patients completed measures of physical, psychological, and cognitive functions and provided blood samples for analyses of DNAm age at baseline and post-intervention. Paired t-tests or Wilcoxon signed rank tests assessed changes in DNAm ages, and Spearman's correlation assessed the relationships between accelerated ages and functions.

RESULTS

We included 20 patients (mean age: 72 years, range 62-80). Accelerated GrimAge, accelerated PhenoAge, and DunedinPACE were stable from baseline to post-intervention. At baseline, DunedinPACE was correlated with worse grip strength (r = -0.41, p = 0.08). From baseline to post-intervention, decreases in accelerated GrimAge (r = -0.50, p = 0.02), accelerated PhenoAge (r = - 0.39, p = 0.09), and DunedinPace (r = - 0.43, p = 0.06) were correlated with increases in distance walked on 6-min walk test. Decreases in accelerated GrimAge (r = - 0.49, p = 0.03), accelerated PhenoAge (r = - 0.40, p = 0.08), and DunedinPace (r = - 0.41, p = 0.07) were correlated with increases in in grip strength.

CONCLUSIONS

Among older adults with myeloid malignancies receiving chemotherapy, GrimAge and PhenoAge on average are stable after a mHealth exercise intervention. Decreases in accelerated GrimAge, accelerated PhenoAge, and DunedinPACE over 8-12 weeks of exercise were correlated with increased physical performance. Future trials assessing the effects of exercise on treatment-related toxicities should evaluate DNAm age. Trial registration Clinicaltrials.gov identifier: NCT04981821.

Patient preferences, regret, and health-related quality of life among older adults with acute myeloid leukemia: A pilot longitudinal study

INTRODUCTION

Acute myeloid leukemia (AML) is associated with poor outcomes and is generally incurable. Therefore, understanding preferences of older adults with AML is critical. We sought to assess whether best-worst scaling (BWS) can be used to capture attributes considered by older adults with AML when making initial treatment decisions and longitudinally, as well as assess changes in health-related quality of life (HRQoL) and decisional regret over time.

MATERIALS AND METHODS

In a longitudinal study for adults ≥60 years with newly diagnosed AML, we collected: (1) attributes of treatment most important to patients using BWS, (2) HRQoL using EQ-5D-5L, (3) decisional regret using the Decisional Regret Scale, and (4) treatment worthiness using the "Was it worth it?" questionnaire. Data was collected at baseline and over six months. A hierarchical Bayes model was used to allocate percentages out of 100%. Due to small sample size, hypothesis testing was performed at α = 0.10 (2-tailed). We analyzed how these measures differed by treatment choice (intensive vs. lower intensity treatment).

RESULTS

Mean age of patients was 76 years (n = 15). At baseline, the most important attributes of treatment to patients were response to treatment (i.e., chance that the cancer will respond to treatment; 20.9%). Compared to those who received lower intensity treatment (n = 7) or best supportive care (n = 2), those who received intensive treatment (n = 6) generally ranked "alive one year or more after treatment" (p = 0.03) with higher importance and ranked "daily activities" (p = 0.01) and "location of treatment" (p = 0.01) with less importance. Overall, HRQoL scores were high. Decisional regret was mild overall and lower for patients who chose intensive treatment (p = 0.06).

DISCUSSION

We demonstrated that BWS can be used to assess the importance of various treatment attributes considered by older adults with AML when making initial treatment decisions and longitudinally throughout treatment. Attributes of treatment important to older patients with AML differed between treatment groups and changed over time. Interventions are needed to re-assess patient priorities throughout treatment to ensure care aligns with patient preferences.

Advance care planning in older patients with acute myeloid leukemia and myelodysplastic syndromes

INTRODUCTION

Older patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) have worse survival rates compared to younger patients, and experience more intense inpatient healthcare at the end of life (EOL) compared to patients with solid tumors. Advance care planning (ACP) has been shown to limit aggressive and burdensome care at EOL for patients with AML and MDS. The purpose of this study was to better understand ACP from the perspective of clinicians, older patients with AML and MDS, and their caregivers.

MATERIALS AND METHODS

We conducted semi-structured interviews with 45 study participants. Interviews were audio-recorded and transcribed. Open coding and focused content analysis were used to organize data and develop and contextualize categories and subcategories.

RESULTS

Guided by our specific aims, we developed four themes: (1) The language of ACP and medical order for life-sustaining treatment (MOLST) does not resonate with patients, (2) There is no uniform consensus on when ACP is currently happening, (3) Oncology clinician-perceived barriers to ACP (e.g., patient discomfort, patient lack of knowledge, and lack of time), and (4) Patients felt that they are balancing fear and hope when navigating their AML or MDS diagnosis.

DISCUSSION

The results of this study can be used to develop interventions to promote serious illness conversations for patients with AML and MDS and their caregivers to ensure that patient care aligns with patient values.

The role of social networks in prognostic understanding of older adults with advanced cancer

OBJECTIVES

Explore how older patients utilize their social networks to inform prognostic understanding.

METHODS

In a pilot study of adults (≥65 years old) with advanced cancer, 16 patients completed surveys, social network maps, and semi-structured interviews exploring with whom they preferred to communicate about their illness. Interviews were analyzed using open-coding, and codes were categorized into emergent themes. Social network maps and themes were analyzed via mixed-methods social network analysis (MMSNA). Three case examples with diverse network characteristics and communication patterns were selected for further analysis.

RESULTS

Three overarching themes (i.e., prognostic understanding, social support, and therapeutic alliance) revealed that patients' prognostic understanding was strongly influenced by the quality of the social support patients perceived from members of their social networks. Patients demonstrated prognostic understanding when they reported close relationships and open communication with their network members. Case examples revealed some ways that patients sought information and had better sense of their prognosis when they had supportive social networks.

CONCLUSION

Findings illustrate how understanding social networks may provide information on how older adults with cancer seek, share, and process prognostic information.

Patient-centered communication tool for older patients with acute myeloid leukemia, their caregivers, and oncologists: A single-arm pilot study

BACKGROUND

In a single-arm pilot study, we assessed the feasibility and usefulness of an innovative patient-centered communication tool (UR-GOAL tool) that addresses aging-related vulnerabilities, patient values, and prognostic awareness for use in treatment decision making between older adults with newly diagnosed acute myeloid leukemia (AML), their caregivers, and oncologists.

METHODS

Primary feasibility metric was retention rate; >50% was considered feasible. We collected recruitment rate, usefulness, and outcomes including AML knowledge (range 0-14) and perceived efficacy in communicating with oncologists (range 5-25). Due to the pilot nature and small sample size, hypothesis testing was performed at α = 0.10.

RESULTS

We included 15 patients (mean age 76 years, range 64-88), 12 caregivers, and 5 oncologists; enrollment and retention rates for patients were 84% and 73%, respectively. Patients agreed that the UR-GOAL tool helped them understand their AML diagnosis and treatment options, communicate with their oncologist, and make more informed decisions. From baseline to post-intervention, patients and caregivers scored numerically higher on AML knowledge (patients: +0.6, p = 0.22; caregivers: +1.1, p = 0.05) and perceived greater efficacy in communicating with their oncologists (patients: +1.5, p = 0.22; caregivers: +1.2, p = 0.06).

CONCLUSION

We demonstrated that it is feasible to incorporate the UR-GOAL tool into treatment decision making for older patients with AML, their caregivers, and oncologists.

A Systematic Review of Decision Aids in Hematologic Malignancies: What Are Currently Available and What Are We Missing?

BACKGROUND

Patient decision aids (PDAs) are tools designed to facilitate decision-making. In this systematic review, we summarized existing studies on the development and evaluation of PDAs for patients with hematologic malignancies.

PATIENTS AND METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for articles in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov. We included studies, abstracts, and clinical trial protocols available in English involving PDAs for patients age ≥18 diagnosed with a hematologic malignancy and/or their caregivers. Data were summarized using descriptive statistics.

RESULTS

Of the 5281 titles/abstracts screened, 15 were included: 1 protocol, 7 abstracts, and 7 full-texts. Six were PDA developmental studies, 6 were pilot studies, and 3 were randomized trials. PDA formats included electronic with web content, videos, and/or audio, questionnaires, bedside instruments, and a combination of various formats. Average participant age ranged from 36.0 to 62.4 years. Patients and caregivers identified efficacy, adverse effects, cost, and quality of life as important decision-making factors. PDAs were associated with increased knowledge and patient satisfaction as well as decreased decisional conflict and attitudinal barriers. Research on PDAs for adult patients with hematologic malignancies and their caregivers is limited. Among the studies, PDAs appear to support patients in shared decision-making.

CONCLUSION

While current literature examining the use of PDAs for adults with hematologic malignancies is limited, the positive impact of PDAs on shared decision-making and patient outcomes warrants additional research in this field.

Older adults with advanced cancer are selective in sharing and seeking information with social networks

BACKGROUND

Little is known about how older adults (OA) with advanced cancer interact with social network members (NM), and the nature of communication. This qualitative study aimed to characterize the processes by which OAs with cancer engage with NMs regarding their illness.

METHODS

OAs 65 + with advanced cancer and considering treatment (n = 29) and NMs (n = 18) underwent semi-structured interviews asking 1) about their illness understanding; 2) to identify NMs with whom OAs discuss health-related matters; and 3) to describe the content, process, and impact of those illness-related conversations. Three coders analyzed transcribed interviews. Codes were categorized and emergent themes were identified to generate hypotheses.

RESULTS

OAs seek NMs with medical backgrounds for cancer-related information and NMs with personal experience of a serious illness for emotional support. Patients characterize geographical location, frequency of communication, and length of NM relationship as factors that influence the nature of support the NM provides. Additionally, differences emerged between OA and NM perspectives on the depth of conversations and decision-making.

CONCLUSIONS

A better characterization of how OAs' seek and share information and support may improve medical communication, disease understanding, and support goals-concordant care.

Advanced care planning (ACP) intervention for older patient with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS)

e19004

Background: The Serious Illness Care Program (SICP) is an evidence-based intervention that promotes ACP for patients with advanced cancer. As part of a study to adapt the SICP for older patients with AML and MDS, we identified clinician and patient reported barriers to ACP for this population, and their suggestions to improve ACP. Methods: In single-center qualitative study, we conducted semi-structured interviews with 14 oncology clinicians and 7 patients with AML or MDS. Interviews were audio-recorded and transcribed. Two investigators independently coded all transcripts using MAXQDA and resolved discrepancies through iteration. Direct content analysis techniques were used to focus on ACP barriers and suggestions. Results: Mean ages of clinicians and patients were 45 and 73, respectively. Majority of patients were not familiar with ACP. All patients had a healthcare proxy. Half of patients were familiar with a Medical Orders for Life-Sustaining Treatment (MOLST) form. Two major themes identified by clinicians and patients were: 1) Discomfort and logistics as ACP barriers (Table) and 2) ACP visit structure. Both clinicians and patients suggested the importance of earlier ACP visits. Clinicians suggested separate outpatient ACP visits, while patients suggested ACP after in-depth treatment discussion. Conclusions: Discomfort and logistics were identified as major barriers to ACP. Initiating ACP earlier was identified as a possible solution by clinicians and patients. Feedback obtained will be used to adapt the SICP to be delivered via Telehealth in a single arm pilot study.[Table: see text]

Protocol for a pilot randomized controlled trial of a mobile health exercise intervention for older patients with myeloid neoplasms (GO-EXCAP 2)

INTRODUCTION

We have shown the Exercise for Cancer Patients (EXCAP©®) exercise program improved physical function and symptoms and reduced inflammatory markers in patients with cancer. However, adherence to exercise was lower in older adults compared to their younger counterparts. We then leveraged a mobile app to deliver EXCAP©® and adapted the intervention [Geriatric-Oncology (GO)-EXCAP] for older patients with myeloid neoplasms. In this pilot randomized trial, the primary goal is to determine effect sizes. We propose to assess the preliminary efficacy of GO-EXCAP compared to a behavioral placebo control on physical function, patient-reported outcomes (fatigue, mood, and quality of life), and inflammatory markers in 100 patients aged ≥60 years with myeloid neoplasms receiving outpatient chemotherapy.

METHODS

GO-EXCAP consists of the EXCAP©® exercise prescription (daily home-based progressive aerobic walking and resistance exercises with rated perceived exercise of 5-8), EXCAP©® kit (i.e., activity tracker, resistance bands, print manual, bag), a mobile app, and an in-person or virtual session with the exercise physiologist to deliver exercise prescription. The intervention will last for three cycles of chemotherapy (approximately 12 weeks). The primary outcome measure will be physical function (Short Physical Performance Battery). Secondary outcome measures include fatigue (Brief Fatigue Inventory), mood (Center for Epidemiologic Studies Depression Scale), and quality of life (Functional Assessment of Cancer Therapy-Leukemia). Exploratory outcome measures include inflammatory markers.

DISCUSSION

Older adults with myeloid neoplasms receiving outpatient chemotherapy serve as an ideal model for studying an individually tailored mobile health exercise intervention in vulnerable older patients receiving cancer treatments to prevent physical function decline and improve symptoms.

Social Justice and Equity: Why Older Adults With Cancer Belong-A Life Course Perspective

The population of older adults with cancer in the United States is rapidly increasing, which will have a substantial impact on the oncology and public health workforces across the cancer continuum, from prevention to end of life. Unfortunately, inequities in existing social structures that cause increased psychosocial stressors have led to disparities in the incidence of cancer and the morbidity and mortality of cancer for individuals from marginalized backgrounds. It is imperative that older adults, especially those from historically marginalized backgrounds, be adequately represented in all stages of cancer research to address health inequities. Continued efforts and progress toward achieving social justice and health equity require a deeper commitment to and better understanding of the impact of social determinants of health within the cancer domain. Undoubtedly, a more holistic and integrated view that extends beyond the biologic and genetic factors of health must be adopted for health entities to recognize the critical role of environmental, behavioral, and social determinants in cancer health disparities. Against this backdrop, this paper uses a life course approach to present a multifactorial framework for understanding and addressing cancer disparities in an effort to advance social justice and health equity for racially and ethnically diverse older adults.

Association of Prognostic Understanding With Health Care Use Among Older Adults With Advanced Cancer: A Secondary Analysis of a Cluster Randomized Clinical Trial

IMPORTANCE

A poor prognostic understanding regarding curability is associated with lower odds of hospice use among patients with cancer. However, the association between poor prognostic understanding or prognostic discordance and health care use among older adults with advanced incurable cancers is not well characterized.

OBJECTIVE

To evaluate the association of poor prognostic understanding and patient-oncologist prognostic discordance with hospitalization and hospice use among older adults with advanced cancers.

DESIGN, SETTING, AND PARTICIPANTS

This was a post hoc secondary analysis of a cluster randomized clinical trial that recruited patients from October 29, 2014, to April 28, 2017. Data were collected from community oncology practices affiliated with the University of Rochester Cancer Center National Cancer Institute Community Oncology Research Program. The parent trial enrolled 541 patients who were aged 70 years or older and were receiving or considering any line of cancer treatment for incurable solid tumors or lymphomas; the patients' oncologists and caregivers (if available) were also enrolled. Patients were followed up for at least 1 year. Data were analyzed from January 3 to 16, 2021.

MAIN OUTCOMES AND MEASURES

At enrollment, patients and oncologists were asked about their beliefs regarding cancer curability (100%, >50%, 50%, <50%, and 0%; answers other than 0% reflected poor prognostic understanding) and life expectancy (≤6 months, 7-12 months, 1-2 years, 2-5 years, and >5 years; answers of >5 years reflected poor prognostic understanding). Any difference between oncologist and patient in response options was considered discordant. Outcomes were any hospitalization and hospice use at 6 months captured by the clinical research associates.

RESULTS

Among the 541 patients, the mean (SD) age was 76.6 (5.2) years, 264 of 540 (49%) were female, and 486 of 540 (90%) were White. Poor prognostic understanding regarding curability was reported for 59% (206 of 348) of patients, and poor prognostic understanding regarding life expectancy estimates was reported for 41% (205 of 496) of patients. Approximately 60% (202 of 336) of patient-oncologist dyads were discordant regarding curability, and 72% (356 of 492) of patient-oncologist dyads were discordant regarding life expectancy estimates. Poor prognostic understanding regarding life expectancy estimates was associated with lower odds of hospice use (adjusted odds ratio, 0.30; 95% CI, 0.16-0.59). Discordance regarding life expectancy estimates was associated with greater odds of hospitalization (adjusted odds ratio, 1.64; 95% CI, 1.01-2.66).

CONCLUSIONS AND RELEVANCE

This study highlights different constructs of prognostic understanding and the need to better understand the association between prognostic understanding and health care use among older adult patients with advanced cancer.

Association Between Caregiver-Oncologist Discordance in Patient's Life Expectancy Estimates and Caregiver Perceived Autonomy Support by the Oncologist

BACKGROUND

Caregiver perceived autonomy support by the oncologist is important for caregiver well-being and may be affected by the patient's survival. We determined the association of caregiver-oncologist discordance in patient's life expectancy estimates with perceived autonomy support over time and whether the association differed by patient survival status.

MATERIALS AND METHODS

We used data from a geriatric assessment cluster-randomized trial (URCC 13070) that recruited patients aged at least 70 years with incurable cancer considering or receiving treatment, their caregivers, and their oncologists. At baseline, caregivers and oncologists were asked to estimate patient's life expectancy (0-6 months, 7-12 months, 1-2 years, 2-5 years, and >5 years; any difference in response was considered discordant). At 4-6 weeks, 3 months, and 6 months, caregivers completed the Health Care Climate Questionnaire (HCCQ), which measured perceived autonomy support by the oncologist. Generalized estimating equation modeling was conducted to assess the association of baseline caregiver-oncologist discordance with longitudinal HCCQ scores, stratified by patient 6-month survival status.

RESULTS

Discordant life expectancy estimates were present in 72.0% of dyads. In multivariate analyses, caregiver-oncologist discordance in patient's life expectancy estimates was associated with higher caregiver HCCQ scores. In stratified analysis, caregiver-oncologist discordance was associated with lower caregiver HCCQ scores (β = -3.46; 95% CI, -4.64 to -2.29) among patients who died within 6 months but with higher caregiver HCCQ scores (β = 1.33; 95% CI, 0.63-2.04) among patients who survived beyond 6 months.

CONCLUSION

Interventions aimed at mitigating discordance need to consider its association with caregiver perceived autonomy support and patient's survival in order to better inform caregiver expectations.

IMPLICATIONS FOR PRACTICE

Among patients who died within the first 6 months, caregivers who estimated a different length of life for the patient compared with oncologists were more likely to report lower support from the oncologist, whereas the opposite relationship was seen within patients who survived beyond the first 6 months. When designing interventions to improve caregiver understanding of the patient's prognosis, its relationship with caregiver-perceived support and patient's survival needs to be considered.

Developing and adapting a mobile health exercise intervention for older patients with myeloid neoplasms: A qualitative study

INTRODUCTION

Older patients with myeloid neoplasms (MN) receiving outpatient chemotherapy are at risk of experiencing treatment-related toxicities such as functional decline. A mobile health (mHealth) exercise intervention may ameliorate these toxicities. This qualitative study aimed to inform the design of a mHealth exercise intervention for this population.

METHODS

This was a qualitative study of thirteen patients aged ≥60 years receiving hypomethylating agents for MN. EXCAP©® is a home-based walking and progressive resistance exercise program. We combined EXCAP©® with a mobile app; the combination (GO-EXCAP Mobile App) has not been previously tested. A brief verbal description about the intervention was provided to the participants but they did not perform it. Participants were interviewed and inductive thematic analysis was used to analyze the data.

RESULTS

Mean age was 71.6 (SD 8.5). Three themes were identified: 1) Perceptions of the intervention feasibility, 2) Ways to leverage the app to deliver the exercise intervention, and 3) Personalized exercise goals. Walking and resistance exercises were perceived to be feasible. Patients were comfortable initiating the intervention in cycle 2 of chemotherapy, with exercise increments occurring from week 2-4 of the cycle. Ways to leverage the app to deliver EXCAP©® include 1) Video feature for exercise demonstration and interactions, and 2) Exercise data and symptom surveys to be communicated to the exercise physiologist and primary oncology team. Preservation of existing function and activity was an important goal to participants.

CONCLUSIONS

Our findings provide insights about the preferences of older adults with MN for a mHealth exercise intervention.

Prognostic understanding, hospitalization, and hospice use among older patients with advanced cancer

12037

Background: Poor prognostic understanding of curability is associated with lower hospice use in patients with advanced cancer. Little is known if this holds true for older adults specifically. In addition, prognostic understanding are variably assessed and defined in prior studies. We evaluated the associations of poor prognostic understanding and patient-oncologist discordance in both curability and survival estimates with hospitalization and hospice use in older patients with advanced cancer. Methods: We utilized data from a national geriatric assessment cluster-randomized trial (URCC 13070: PI Mohile) that recruited 541 patients aged ≥70 with incurable solid tumor or lymphoma considering any line of cancer treatment and their oncologists. At enrollment, patients and oncologists were asked about their beliefs about cancer curability (options: 100%, > 50%, 50/50, < 50%, 0%, and uncertain) and estimates of patient’s survival (options: 0-6 months, 7-12 months, 1-2 years, 2-5 years, and > 5 years). Non-0% options were considered poor understanding of curability (uncertain was removed from the analysis) and > 5 years was considered poor understanding of survival estimates. Any difference in response options was considered discordant. We used generalized estimating equations to estimate adjusted odds ratios (AOR) assessing associations of poor prognostic understanding and discordance with hospitalization and hospice use at 6 months, adjusting for covariates and practice clusters. Results: Poor prognostic understanding of curability and survival estimates occurred in 59% (206/348) and 41% (205/496) of patients, respectively. Approximately 60% (202/336) and 72% (356/492) of patient-oncologist dyads were discordant in curability and survival estimates, respectively. In the first 6 months after enrollment, 24% were hospitalized and 15% utilized hospice. Poor prognostic understanding of survival estimates was associated with lower odds of hospice use (AOR 0.30, 95% CI 0.16-0.59) (Table). Discordance in survival estimates was associated with greater odds of hospitalization (AOR 1.64, 95% CI 1.01-2.66). Conclusions: Prognostic understanding may be associated with hospitalization or hospice use depending on how patients were queried about their prognosis and whether oncologists’ estimates were considered.[Table: see text]

Characteristics Associated With Functional Changes During Systemic Cancer Treatments: A Systematic Review Focused on Older Adults

BACKGROUND

Maintaining functional status is important to older adults with cancer, but data are limited on how systemic treatments affect functional status. We systematically reviewed changes in functional status during systemic cancer treatments and identified characteristics associated with functional decline and improvement.

METHODS

We searched PubMed, Embase, Web of Science, and Cochrane Register of Controlled Trials for articles examining characteristics associated with functional changes in older adults during systemic cancer treatment published in English between database inception and January 11, 2019 (PROSPERO CRD42019123125). Findings were summarized with descriptive statistics. Study characteristics between older adult-specific and non-older adult-specific studies were compared using the Fisher exact test.

RESULTS

We screened 15,244 titles/abstracts and 519 full texts. The final analysis included 44 studies, which enrolled >8,400 patients; 39% of studies focused on older adults (1 study enrolled adults aged ≥60 years, 10 enrolled adults aged ≥65 years, and 6 enrolled adults aged ≥70 years). Almost all studies (98%) used patient-reported outcomes to measure functional status; only 20% used physical performance tests. Reporting of functional change was heterogeneous, with 48% reporting change scores. Older adult-specific studies were more likely to analyze functional change dichotomously (29% vs 4%; P=.008). Functional decline ranged widely, from 6% to 90%. The most common patient characteristics associated with functional decline were older age (n=7 studies), worse performance status (n=4), progressive disease status (n=4), pain (n=4), anemia (n=4), and worse nutritional status (n=4). Twelve studies examined functional improvement and identified 11 unique associated characteristics.

CONCLUSIONS

Functional decline is increasingly recognized as an important outcome in older adults with cancer, but definitions and analyses are heterogeneous, leading to a wide range of prevalence. To identify patients at highest risk of functional decline during systemic cancer treatments, trials need to routinely analyze functional outcomes and measure characteristics associated with decline (eg, nutrition).

Caregiver-Oncologist Prognostic Concordance, Caregiver Mastery, and Caregiver Psychological Health and Quality of Life

BACKGROUND

Caregivers of adults with cancer often report a different understanding of the patient's prognosis than the oncologist. We examine the associations of caregiver-oncologist prognostic concordance with caregiver depressive symptoms, distress, and quality of life (QoL). We also explore whether these relationships differed by caregiver environment mastery, an individual's sense of control, and effectiveness in managing life situations.

MATERIALS AND METHODS

We used data from a national geriatric assessment cluster-randomized trial (URCC 13070) that recruited patients aged 70 years and older with incurable cancer considering any line of cancer treatment at community oncology practices, their caregivers, and their oncologists. At enrollment, caregivers and oncologists estimated the patient's prognosis (0-6 months, 7-12 months, 1-2 years, 2-5 years, and >5 years; identical responses were concordant). Caregivers completed the Ryff's environmental mastery at enrollment. At 4-6 weeks, caregivers completed the Patient Health Questionnaire-2 (depressive symptoms), distress thermometer, and 12-Item Short-Form Health Survey (quality of life [QoL]). We used generalized estimating equations in models adjusted for covariates. We then assessed the moderation effect of caregiver mastery.

RESULTS

Of 411 caregiver-oncologist dyads (mean age = 66.5 years), 369 provided responses and 28% were concordant. Prognostic concordance was associated with greater caregiver depressive symptoms (β = 0.30; p = .04) but not distress or QoL. A significant moderation effect for caregiver depressive symptoms was found between concordance and mastery (p = .01). Specifically, among caregivers with low mastery (below median), concordance was associated with greater depressive symptoms (β = 0.68; p = .003).

CONCLUSIONS

Caregiver-oncologist prognostic concordance was associated with caregiver depressive symptoms. We found a novel moderating effect of caregiver mastery on the relationship between concordance and caregiver depressive symptoms.

IMPLICATIONS FOR PRACTICE

Caregiver-oncologist prognostic concordance is associated with greater caregiver depressive symptoms, particularly in those with low caregiver mastery. When discussing prognosis with caregivers, physicians should be aware that prognostic understanding may affect caregiver psychological health and should assess their depressive symptoms. In addition, while promoting accurate prognostic understanding, physicians should also identify strengths and build resilience among caregivers.

Caregiver-oncologist concordance in patient prognosis, caregiver depression, and caregiver mastery

143

Background: Caregivers of older adults with advanced cancer often have a different understanding of the patient’s prognosis compared with their oncologist. Among patients, accurate prognostic awareness is associated with greater depressive symptoms, except when patients utilize more adaptive coping skills. We examined the relationship between caregiver-oncologist prognostic concordance and caregiver depressive symptoms and explored whether this relationship differed by caregiver mastery, the capacity to cope, adjust, and adapt to problems. Methods: We utilized data from a national geriatric assessment cluster-randomized trial (URCC 13070: PI Mohile) that recruited patients aged ≥70 with incurable cancer considering any line of cancer treatment at community oncology practices, their caregivers, and oncologists. At enrollment, caregivers and oncologists estimated the patient’s prognosis (0-6 months, 7-12 months, 1-2 years, 2-5 years, > 5 years); same response was considered concordant. Caregivers completed Ryff’s mastery subscale (range 7-35, higher is better) at enrollment and depression screen (the Patient Health Questionnaire (PHQ)-2 (range 0-6) 4-6 weeks later. To assess the association of prognostic concordance with caregiver depressive symptoms, we used generalized estimating equations in models adjusted for cancer type, study arm, practice sites, and caregiver demographics. We then assessed moderation effect of caregiver mastery on this association. Results: Among 410 caregiver-oncologist dyads, mean caregiver age was 66.5, 75% were female, and 26% were caregivers of patients with lung cancer. Mean mastery score at enrollment was 27.6 (SD 4.7) and 19% screened positive on PHQ-2 at week 4-6. Among dyads who provided response (N = 370), 28% were concordant. Prognostic concordance was associated with higher caregiver depressive symptoms (β = 0.30; p = 0.04). Significant moderation effect was found between concordance and mastery for caregiver depressive symptoms (p = 0.02). Among caregivers with low mastery ( < median), prognostic concordance was associated with higher depressive symptoms (β = 0.68; p = 0.003). Among caregivers with high mastery (≥median), concordance was not associated with depressive symptoms (β = -0.06; p = 0.67). Conclusions: There is a need to study how prognostic understanding might lead to depression in at-risk caregivers. Interventions targeting caregiver prognostic understanding need to consider its relationship with depressive symptoms, while seeking to increase caregiver mastery.

Barriers to Hematopoietic Cell Transplantation for Adults in the United States: A Systematic Review with a Focus on Age

Hematopoietic cell transplantation (HCT) is an effective treatment for many hematologic malignancies, and its utilization continues to rise. However, due to the difficult logistics and high cost of HCT, there are significant barriers to accessing the procedure; these barriers are likely greater for older patients. Although numerous factors may influence HCT access, no formal analysis has detailed the cumulative barriers that have been studied thus far. We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to better categorize the barriers to access and referral to HCT, with a focus on the subgroup of older patients. We searched for articles published in English from PubMed, Embase, Cumulative Index for Nursing and Allied Health, and Cochrane Central Register of Controlled Trials between the database inception and January 31, 2020. We selected articles that met the following inclusion criteria: (1) study design: qualitative, cross-sectional, observational cohort, or mixed-method study designs; (2) outcomes: barriers related to patient and physician access to HCT; and (3) population: adults aged ≥18 years with hematologic malignancies within the United States. Abstracts without full text were excluded. QUALSYST methodology was used to determine article quality. Data on the barriers to access and referral for HCT were extracted, along with other study characteristics. We summarized the findings using descriptive statistics. We included 26 of 3859 studies screened for inclusion criteria. Twenty studies were retrospective cohorts and 4 were cross-sectional. There was 1 prospective cohort study and 1 mixed-method study. Only 1 study was rated as high quality, and 16 were rated as fair. Seventeen studies analyzed age as a potential barrier to HCT referral and access, with 16 finding older age to be a barrier. Other consistent barriers to HCT referral and access included nonwhite race (n = 16/20 studies), insurance status (n = 13/14 studies), comorbidities (n = 10/11 studies), and lower socioeconomic status (n = 7/8 studies). High-quality studies are lacking related to HCT barriers. Older age and nonwhite race were consistently linked to reduced access to HCT. To produce a more just health care system, strategies to overcome these barriers for vulnerable populations should be prioritized. Examples include patient and physician education, as well as geriatric assessment guided care models that can be readily incorporated into clinical practice.

Patient factors associated with changes in functional status during systemic cancer therapy in older adults: A systematic review

e24022

Background: Maintaining function and preventing functional decline during cancer treatment is critically important to older adults. This systematic review characterized and identified patient factors associated with functional change during systemic cancer therapy in older adults. Methods: Following PRISMA guidelines, we searched PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials for articles examining changes in function during systemic cancer treatment published in English through 1/11/19. Studies were eligible if they included adults age >65 and analyzed associations between patient factors and change in function. At least two independent investigators reviewed each article with discrepancies resolved by consensus. Major findings were summarized; no meta-analysis was planned a priori given the heterogeneity in studies. Results: We screened 15,244 titles/abstracts and 519 full texts. The final analysis included 69 studies, which enrolled > 11,000 patients with cancer. Most studies enrolled adults of all ages; 20% included only adults age >65 and 13% only adults age >70. A quarter of studies enrolled patients with lung cancer while 22% included all solid tumors and hematologic malignancies. The majority of studies evaluated function during chemotherapy (96%) with 9% including targeted therapy and 4% immunotherapy. Function was primarily measured with patient-reported outcomes (93% of studies). Reporting of functional change was heterogeneous with many reporting change scores or means at multiple time points. Among studies that reported the percentage of patients who developed functional decline, results ranged widely from 6% to 90%. Functional improvement occurred among 2% to 57% of patients. The most common patient factors associated with functional decline during systemic cancer therapy were older age (n = 8 studies), fatigue (n = 8), worse baseline performance status (n = 8) and physical activity (n = 5), and anemia (n = 5). Only 10 studies examined factors associated with functional recovery, identifying 12 unique patient factors. Conclusions: Among older adults with cancer, functional changes during systemic cancer therapy are common. Interventions to target modifiable patient factors associated with functional decline are needed to help patients maintain or improve function during treatment. Additionally, evaluating both functional decline and improvement is necessary to better characterize functional trajectories during systemic cancer therapy.

Modulation of proteoglycan receptor PTPσ enhances MMP-2 activity to promote recovery from multiple sclerosis

Multiple Sclerosis (MS) is characterized by focal CNS inflammation leading to the death of oligodendrocytes (OLs) with subsequent demyelination, neuronal degeneration, and severe functional deficits. Inhibitory chondroitin sulfate proteoglycans (CSPGs) are increased in the extracellular matrix in the vicinity of MS lesions and are thought to play a critical role in myelin regeneration failure. We here show that CSPGs curtail remyelination through binding with their cognate receptor, protein tyrosine phosphatase σ (PTPσ) on oligodendrocyte progenitor cells (OPCs). We report that inhibition of CSPG/PTPσ signaling by systemically deliverable Intracellular Sigma Peptide (ISP), promotes OPC migration, maturation, remyelination, and functional recovery in animal models of MS. Furthermore, we report a downstream molecular target of PTPσ modulation in OPCs involving upregulation of the protease MMP-2 that allows OPCs to enzymatically digest their way through CSPGs. In total, we demonstrate a critical role of PTPσ/CSPG interactions in OPC remyelination in MS.

Demyelination failure in multiple sclerosis (MS) may contribute to the disease progression. This study shows that chondroitin sulfate proteoglycans (CSPGs) can inhibit remyelination in an animal model of MS via CSPG binding with the receptor PTPσ on oligodendrocyte progenitor cells, and disruption of this interaction can promote recovery in the animal models of MS.
