Prognostic awareness and willingness to explore prognosis in older adults with cancer.

INTRODUCTION: Prognostic awareness varies widely among older adults with cancer. Accurate prognostic awareness helps to ensure delivery of care that is aligned with the patient's goals. Understanding factors associated with poor prognostic awareness in older adults with cancer may help identify which patients may need interventions to improve prognostic awareness. In this study, we assessed factors associated with poor prognostic awareness in older adults with cancer. MATERIALS AND METHODS: We conducted a cross-sectional analysis of older patients with cancer referred to a geriatric oncology clinic at the University of Rochester. We provided paper questionnaires for patients to complete prior to their clinic assessment. Questionnaires asked patients to estimate their overall life expectancy and the life expectancy of a person of the same age with normal health. Prognostic awareness was considered poor if patients estimated living at least as long as a person of the same age with normal health. We assessed independent demographic and clinical variables (age, sex, race, income, religion, living situation, education, marital status, and cancer type and stage), aging-related factors (comorbidities, cognition, depression, social support, nutritional status, and physical function), and willingness to discuss prognosis. Factors significant at p ≤ 0.15 on bivariate analyses were included in the multivariable logistic regression model. RESULTS: We included 257 patients; the mean age was 80 years (standard deviation [SD] 6.8, range 55-97), 37% were female, 71% were White, and 44% were married. Nearly two-thirds of patients (62%) had poor prognostic awareness: 7% estimated they would live longer than and 55% estimated they would live as long as a person of the same age with normal health. Half (49%) were willing to discuss prognosis, 29% were not, and 22% did not answer. On multivariable analysis, factors associated with poor prognostic awareness were older age [one-year increase; adjusted odds ratio (AOR) 1.07, 95% confidence interval (CI) 1.02-1.12], race other than White (AOR 2.35, 95% CI 1.09-5.06), unwillingness to discuss prognosis (AOR 3.33, 95% CI 1.54-7.18), and stage I-III cancer (vs. stage IV, AOR 3.83, 95% CI 1.8-8.17). DISCUSSION: In a cohort of older patients with cancer, approximately two-thirds had poor prognostic awareness. Older age, race other than White, stage I-III cancer, and unwillingness to discuss prognosis were associated with higher odds of poor prognostic awareness. Interventions aiming to improve patients' prognostic awareness may need to gauge patients' willingness to discuss prognosis.

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.

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.

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.

Adaptation of Serious Illness Care Program to be delivered via telehealth for older patients with hematologic malignancy.

Older patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) experience intense inpatient health care at the end-of-life stage. Early advance care planning may improve care at the end of life for patients with AML or MDS. The Serious Illness Care Program (SICP) is a multicomponent, communication intervention developed to improve conversations about values for patients with serious illnesses. The SICP has been shown to improve the quality and frequency of advance care planning discussions. We adapted the SICP for delivery via telehealth to older patients with AML or MDS. We conducted a single-center qualitative study of 45 participants (25 clinicians, 15 older patients with AML or MDS, and 5 caregivers). Participants, whether clinicians, patients, or caregivers, agreed that the SICP would help older patients with AML or MDS to share their personal values with their care team. Four qualitative themes emerged from our data: (1) serious illness conversations can be conducted via telehealth, (2) older patients have limited experience using technology but are willing and able to learn, (3) patients feel that serious illness conversations will help them understand their AML or MDS diagnosis and prognosis better, and (4) serious illness conversations should be common and routine, not extraordinary. The adapted SICP may provide older patients with AML or MDS an opportunity to share what matters most to them with their care team and may assist oncologists in aligning patient care with patient values. The adapted SICP is the subject of an ongoing single-arm pilot study at the Wilmot Cancer Institute (clinicaltrials.gov identifier: NCT04745676).

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.

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.

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.

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.

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.

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.

Caregiver-oncologist prognostic concordance, caregiving esteem, and caregiver outcomes.

INTRODUCTION: Caregiver-oncologist concordance regarding the patient's prognosis is associated with worse caregiver outcomes (e.g., depressive symptoms), but mechanisms underpinning these associations are unclear. We explored whether caregiving esteem mediates these associations. METHODS: At enrollment, caregivers and oncologists used a 5-point ordinal scale to estimate patient survival; identical responses were considered concordant. At 4-6 weeks, caregivers completed an assessment of the extent to which caregiving imparts self-esteem (Caregiver Reaction Assessment self-esteem subscale; range 0-5; higher score indicates greater esteem). They also completed Patient Health Questionnaire-2 (PHQ-2) for depressive symptoms, Distress Thermometer, and 12-Item Short Form Survey for quality of life (QoL). Mediation analysis with bootstrapping (PROCESS macro by Hayes) was used to estimate the extent to which caregiving mediated the effects of prognostic concordance on caregiver outcomes through caregiving esteem. RESULTS: Prognostic concordance occurred in 28% the caregiver-oncologist dyads; 85% of the discordance were due to caregivers estimating a longer patient's survival. At 4-6 weeks, mean caregiving esteem score was 4.4 (range 1.5-5.0). Lower caregiving esteem mediated the associations of concordance with higher PHQ-2 [indirect effect = 0.12; 95% Confidence Interval (CI) 0.03, 0.27], greater distress (indirect effect =0.25; 95% CI 0.08, 0.48), and poorer QoL (indirect effect = -1.50; 95% CI -3.06, -0.41). Caregiving esteem partially mediated 39%, 64%, and 48% of the associations between caregiver-oncologist concordance and PHQ-2, distress, and SF-12, respectively. CONCLUSIONS: Caregiver-oncologist concordance was associated with lower caregiving esteem. Lower caregiving esteem mediated the negative relationship between caregiver-oncologist concordance and caregiver outcomes.

A single-arm pilot study of a mobile health exercise intervention (GO-EXCAP) in older patients with myeloid neoplasms.

Many older patients with myeloid neoplasms experience treatment-related toxicities. We previously demonstrated that a home-based, progressive aerobic walking and resistance exercise program (EXCAP) improved physical and psychological outcomes in patients with cancer. However, older patients have more difficulty adhering to exercise than younger patients. Reasons may include low motivation, difficulty with transportation, and limited access to exercise professionals. To improve exercise adherence, we integrated a mobile app with EXCAP (GO-EXCAP) and assessed its feasibility and usability in a single-arm pilot study among older patients with myeloid neoplasms undergoing outpatient chemotherapy. GO-EXCAP intervention lasts for 2 cycles of treatment, and the primary feasibility metric was data reporting on the app. Usability was evaluated via the system usability scale (SUS). Patients were interviewed at mid and postintervention to elicit their feedback, and deductive thematic analysis was applied to the transcripts. Twenty-five patients (mean age, 72 years) were recruited. Recruitment and retention rates were 64% and 88%, respectively. Eighty-two percent (18/22) of patients entered some exercise data on the app at least half of the study days, excluding hospitalization (a priori, we considered 70% as feasible). Averaged daily steps were 2848 and 3184 at baseline and after intervention, respectively. Patients also performed resistance exercises 26.2 minutes per day, 2.9 days per week at low intensity (rate of perceived exertion 3.8/10). Usability was above average (SUS, 70.3). In qualitative analyses, 3 themes were identified, including positive experience with the intervention, social interactions, and flexibility. The GO-EXCAP intervention is feasible and usable for older patients with myeloid neoplasms undergoing outpatient chemotherapy. This trial was registered at www.clinicaltrials.gov as #NCT04035499.

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. Trial Registration: ClinicalTrials.gov Identifier: NCT02107443.

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.

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 (ß = -3.46; 95% CI, -4.64 to -2.29) among patients who died within 6 months but with higher caregiver HCCQ scores (ß = 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.
