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.

Trajectories of physical well-being among adults with acute myeloid leukemia

Patients with acute myeloid leukemia (AML) often undergo physical decline leading to negative outcomes. Identification of distinct trajectories may help guide clinical decision making and supportive care interventions. We built group-based trajectory models (GBTM) to find trajectories of change in the Functional Assessment of Cancer Therapy Physical Well-Being sub scale (FACT-PWB, up to 5 timepoints over 0 to 200 days of follow-up) using data from adults with newly diagnosed AML in four supportive care studies. We also estimated the association of baseline characteristics (age, marital status, education, AML risk, baseline FACT-PWB, depression, anxiety) with group membership. Among 343 patients with ≥ 2 FACT-PWB scores, mean age was 69.6 (SD 12.1) years; most had intermediate risk AML (178, 51.8%), received intensive treatment (244, 71.1%), and died during follow up (199, 58.0%). The GBTM with four distinct trajectories showed the best fit. The largest group (N=153, 45.0%) showed slight improvement, while the smallest experienced early decline with later improvement (N=8, 2.4%). Baseline FACT-PWB was the only characteristic statistically significantly associated with group membership. Adults with AML show distinct trajectories of physical well-being, and many experience some decline. Exploring trajectories of self-reported and objective physical function may inform decision making and interventions.

Modifiable fall risk factors among older adults with advanced cancer: Secondary analysis of a cluster-randomized clinical trial

INTRODUCTION

Older adults with cancer have unique fall risk factors related to their disease and treatment such as polypharmacy and neurotoxic treatments. In this secondary analysis, we identified modifiable risk factors associated with future falls among older adults with advanced cancers.

MATERIALS AND METHODS

Data were from the COACH study (ClinicalTrials.gov: NCT02107443; PI: Mohile). Patients were age ≥ 70, had stage III/IV solid tumor or lymphoma, ≥1 geriatric assessment impairment, and were receiving palliative intent treatment. Falls were self-reported at baseline (in the past six months), four to six weeks, three months, and six months. We generated inverse probability weights to account for mortality-related loss to follow-up and applied these in generalized linear mixed models to estimate incidence rate ratios.

RESULTS

Of 541 patients (mean age: 77, standard deviation [SD]: 5.27), 140 (26%) reported prior falls at baseline, and 467 (86%) had falls data for ≥1 follow-up timepoint. Of those, 103 (22%) reported at least one fall during the follow-up period, and 112 (24%) had incomplete follow-up due to death. In fully adjusted models, prior falls and impaired Timed Up and Go score were associated with higher incidence of falls over 6 months.

DISCUSSION

We identified several potentially modifiable fall risk factors in older adults with advanced cancers. Future studies should consider ways to integrate fall risk assessment into ongoing cancer care and intervene to reduce falls in this population.

Chemotherapy-related symptoms and exercise adherence in older patients with myeloid neoplasms

PURPOSE

Exercise may ameliorate treatment-related symptoms, but older adults have lower exercise adherence compared to their younger counterparts due to treatment-related symptoms.

METHODS

We recruited older patients with myeloid neoplasms receiving chemotherapy to a pilot study of a mobile health exercise intervention. Participants entered their steps and resistance data into the app daily, and symptom data twice a week, over an 8-12 week period. In this proof-of-concept analysis, we used a linear mixed-effects model to assess the association of symptoms from the previous week with exercise adherence in the current week among older adults with myeloid neoplasms.

RESULTS

Mean age was 74.3 (SD = 5.0) years (N = 7). At baseline, patients on average walked 2564 daily steps (SD = 1816), which increased to 2967 (SD = 3448) post-intervention. Patients on average performed 3.5 (SD = 2.6) days of resistance training weekly, with mean duration of 21.5 min (SD = 11.6) and rated perceived exertion of 3.68 (SD = 1.78) on a 0-10 scale. Lower average steps in the current week was associated with greater interference with daily activities from pain (β =  - 203.13, p = 0.05), memory (β =  - 492.29, p = 0.09), numbness (β =  - 353.57, p = 0.07), and sadness (β =  - 403.03, p = 0.09) in the previous week. Similarly, lower average resistance minutes in the current week were associated with greater pain, sadness, and anxiety in the previous week.

CONCLUSIONS

We found that greater pain, sadness, and anxiety were associated with lower exercise adherence. Symptom monitoring and management in older adults with myeloid neoplasms receiving chemotherapy can promote exercise adherence and in turn improve symptoms.

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.

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.

Communication About Fall Risk in Community Oncology Practice: The Role of Geriatric Assessment

PURPOSE

Falls are a modifiable source of morbidity for older adults with cancer, yet are underassessed in oncology practice. In this secondary analysis of a nationwide cluster-randomized controlled trial, we examined characteristics associated with patient-oncologist conversations about falls, and whether oncologist knowledge of geriatric assessment (GA) resulted in more conversations.

METHODS

Eligible patients (ClinicalTrials.gov identifier: NCT02107443) were age ≥ 70 years, had stage III/IV solid tumor or lymphoma, were being treated with noncurative treatment intent, and ≥ 1 GA domain impairment. Patients in both arms underwent GA. At practices randomly assigned to the intervention arm, oncologists were provided a GA summary with management recommendations. In both arms, patients had one clinical encounter audio-recorded, transcribed, and coded to categorize whether a conversation about falls occurred. Generalized linear mixed models adjusted for arm, practice site, and other important covariates were used to generate proportions and odds ratios (ORs) from the full sample.

RESULTS

Of 541 patients (intervention N = 293 and usual care N = 248, mean age: 77 years, standard deviation: 5.3), 528 had evaluable audio recordings. More patients had conversations about falls in the intervention versus usual care arm (61.3% v 10.3%, P < .001). Controlling for the intervention and practice site, history of falls (OR, 2.1; 95% CI, 1.3 to 3.6; P = .005) and impaired physical performance (OR, 4.7; 95% CI, 1.7 to 12.8; P = .002) were significantly associated with patient-oncologist conversations about falls.

CONCLUSION

GA intervention increased conversations about falls. History of falls and impaired physical performance were associated with patient-oncologist conversations about falls in community oncology practice.

Modifiable risk factors for falls among older adults with advanced cancer

328

Background: Older adults with cancer are more likely to fall than those without cancer, but the factors driving this increased risk are not fully understood. Falls may lead to injury, dependence, hospitalization, and death. Given the interventions available to reduce fall risk, identifying risk factors amenable to intervention for older adults with cancer is critical to provide targeted care and improve health outcomes. Methods: To examine factors associated with patient-reported falls within a 6 month follow up period, we analyzed data previously collected in a nationwide cluster randomized trial (ClinicalTrials.gov: NCT02107443; PI: Mohile, NCORP UG1CA189961). Patients were eligible if age ≥70, stage III/IV solid tumor or lymphoma with palliative treatment intent, and ≥1 geriatric assessment impairment (GA). A GA summary with tailored recommendations was given to oncologists in practices randomized to the intervention, but not usual care. We combined intervention and usual care groups and evaluated baseline risk factors for falls over a 6 month follow up including: prior falls, fear of falling (FOF), activity limitation due to FOF, activities of daily living, Short Physical Performance Battery, Timed Up and Go (TUG), Older Americans Resources Survey (physical health scale), cognition, polypharmacy, potentially inappropriate medications (PIM), and neurotoxic treatment agents. Incidence rate ratios (IRR) were estimated using generalized linear mixed models controlling for the study arm and practice site. Fully adjusted multivariable models were built for factors associated with follow up falls (p≤0.15) in bivariate. Results: Of 541 patients (mean age: 77, SD: 5.27), 140 (26%) patients had prior falls in the past 6 months. Over 6 months of follow up 467 (86%) had falls data for ≥ 1 follow up timepoint and 344 (64%) had complete follow up. Of those contributing any follow up data 103 patients (22%) reported at least one fall. In adjusted models prior falls, impaired TUG, and number of PIM were associated with higher incidence of falls over 6 months (see Table). Conclusions: Prior falls, TUG, and PIM are prospectively associated with falls among older adults with advanced cancer. These factors are feasible to assess and amenable to interventions such as rehabilitation or deprescribing. Future studies focused on implementation of fall risk reduction in the oncology setting are needed to determine the most effective ways to reduce fall risk in this vulnerable population.

Protocol paper: Multi-site, cluster-randomized clinical trial for optimizing functional outcomes of older cancer survivors after chemotherapy

BACKGROUND

Cancer survivors over the age of 65 have unique needs due to the higher prevalence of functional and cognitive impairment, comorbidities, geriatric syndromes, and greater need for social support after chemotherapy. In this study, we will evaluate whether a Geriatric Evaluation and Management-Survivorship (GEMS) intervention improves functional outcomes important to older cancer survivors following chemotherapy.

METHODS

A cluster-randomized trial will be conducted in approximately 30 community oncology practices affiliated with the University of Rochester Cancer Center (URCC) National Cancer Institute Community Oncology Research Program (NCORP) Research Base. Participating sites will be randomized to the GEMS intervention, which includes Advanced Practice Practitioner (APP)-directed geriatric evaluation and management (GEM), and Survivorship Health Education (SHE) that is combined with Exercise for Cancer Patients (EXCAP©®), or usual care. Cancer survivors will be recruited from community oncology practices (of participating oncology physicians and APPs) after the enrolled clinicians have consented and completed a baseline survey. We will enroll 780 cancer survivors aged 65 years and older who have completed curative-intent chemotherapy for a solid tumor malignancy within four weeks of study enrollment. Cancer survivors will be asked to choose one caregiver to also participate for a total up to 780 caregivers. The primary aim is to compare the effectiveness of GEMS for improving patient-reported physical function at six months. The secondary aim is to compare effectiveness of GEMS for improving patient-reported cognitive function at six months. Tertiary aims include comparing the effectiveness of GEMS for improving: 1) Patient-reported physical function at twelve months; 2) objectively assessed physical function at six and twelve months; and 3) patient-reported cognitive function at twelve months and objectively assessed cognitive function at six and twelve months. Exploratory health care aims include: 1) Survivor satisfaction with care, 2) APP communication with primary care physicians (PCPs), 3) completion of referral appointments, and 4) hospitalizations at six and twelve months. Exploratory caregiver aims include: 1) Caregiver distress; 2) caregiver quality of life; 3) caregiver burden; and 4) satisfaction with patient care at six and twelve months.

DISCUSSION

If successful, GEMS would be an option for a standardized APP-led survivorship care intervention.

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 of Oncologist-Patient Communication With Functional Status and Physical Performance in Older Adults: A Secondary Analysis of a Cluster Randomized Clinical Trial

IMPORTANCE

The functional status and physical performance of older adults with cancer are underassessed and undertreated despite the high prevalence of impaired functional status and physical performance in this population and their associations with chemotherapy-induced toxic effects and mortality.

OBJECTIVE

To examine the association between providing oncologists with a geriatric assessment (GA) summary with recommendations and having oncologist-patient conversations about functional and physical performance.

DESIGN, SETTING, AND PARTICIPANTS

Data for this secondary analysis were collected from October 29, 2014, to April 28, 2017, for a national cluster randomized clinical trial conducted by the University of Rochester Cancer Center National Cancer Institute Community Oncology Research Program evaluating the effect of a GA intervention on patient satisfaction with communication about aging-related concerns. There were 17 practice clusters in the intervention group and 14 in the usual care group. All 541 participants underwent a GA including standardized functional and physical performance measures and had 1 clinical encounter audio-recorded, transcribed, and blindly coded to categorize conversations by GA domain. Participants were aged 70 years or older, with a stage III or IV solid tumor or lymphoma with palliative treatment intent, and impairment in 1 or more GA domain. Statistical analysis was performed from August 18, 2020, to January 10, 2022.

INTERVENTIONS

Oncologist practices randomized to the intervention received a GA summary and validated recommendations for each patient prior to the audio-recorded clinical encounter.

MAIN OUTCOMES AND MEASURES

The primary analysis of this clinical trial assessed the effect of the intervention on patient satisfaction with oncologist communication about aging-related concerns. This secondary analysis assessed the post hoc hypothesis that the intervention would be associated with an increase in the proportion of patients having conversations with their oncologists and receiving oncologist recommendations specific to functional and physical performance concerns.

RESULTS

A total of 541 patients (276 men [51%]; mean [SD] age, 77.5 [5.2] years [range, 70-96 years]) were analyzed at baseline. Excluding 13 patients without audio recordings, 86% of patients (95% CI, 78%-91%) in the intervention group vs 59% of patients (95% CI, 47%-69%; P < .001) receiving usual care had conversations about functional or physical performance. Conversations were more frequently initiated by oncologists in the intervention group (84%; 95% CI, 77%-90%) than oncologists in the usual care group (58%; 95% CI, 45%-70%; P < .001). Oncologists in the intervention group were more likely to address patients' concerns (43%; 95% CI, 33%-53%) than oncologists in the usual care group (17%; 95% CI, 10%-26%; P < .001).

CONCLUSIONS AND RELEVANCE

In this secondary analysis of a cluster randomized clinical trial, providing oncologists with a GA summary was associated with an increase in the number of oncologist-patient conversations about functional and physical performance-related concerns with recommendations to address these concerns. These findings support the use of the GA summary and recommendations as important tools in caring for older adults with advanced cancer and functional or physical impairments.

Using Geriatric Assessment to Guide Conversations Regarding Comorbidities Among Older Patients With Advanced Cancer

PURPOSE

Older patients with advanced cancer often have comorbidities that can worsen their cancer and treatment outcomes. We assessed how a geriatric assessment (GA)-guided intervention can guide conversations about comorbidities among patients, oncologists, and caregivers.

METHODS

This secondary analysis arose from a nationwide, multisite cluster-randomized trial (ClinicalTrials.gov identifier: NCT02107443). Eligible patients were ≥ 70 years, had advanced cancer (solid tumors or lymphoma), and had impairment in at least one GA domain (not including polypharmacy). Oncology practices (n = 30) were randomly assigned to usual care or intervention. All patients completed a GA; in the intervention arm, a GA summary with recommendations was provided to their oncologist. Patients completed an Older Americans Resources and Services Comorbidity questionnaire at screening. The clinical encounter following GA was audio-recorded, transcribed, and coded for topics related to comorbidities. Linear mixed models examined the effect of the intervention on the outcomes adjusting for practice site as a random effect.

RESULTS

Patients (N = 541) were 76.6 ± 5.2 years old; 94.6% of patients had at least one comorbidity with an average of 3.2 ± 1.9. The intervention increased the average number of conversations regarding comorbidities per patient from 0.52 to 0.99 (P < .01). Moreover, there were a greater number of concerns acknowledged (0.52 v 0.32; P = .03) and there was a 2.4-times higher odds of having comorbidity concerns addressed via referral, handout, or other modes (95% CI, 1.3 to 4.3; P = .004). Most oncologists in the intervention arm (76%) discussed comorbidities in light of the treatment plan, and 41% tailored treatment plans.

CONCLUSION

Providing oncologists with a GA-guided intervention enhanced communication regarding comorbidities.

A 10-hour time-restricted eating intervention to address cancer-related fatigue among cancer survivors

12109

Background: Cancer-related fatigue is a common, debilitating condition that can persist for months or years after cancer treatment. Time-restricted eating has been shown to improve circadian rhythm and strengthen rest and activity patterns, and therefore could help reduce persistent fatigue. Herein, we evaluated the feasibility of recruiting cancer survivors to a two-week, single-arm, time-restricted eating intervention with a 10-h eating window, assessed safety of the intervention, monitored adherence, and obtained initial estimates of within-group change in patient-reported fatigue. Methods: We recruited adults 4-60 months post-cancer treatment who had a fatigue level ≥3 on a scale from 0-10 and who did not already consume food within a 10-h window. Participants were asked to consume all food and beverages within a self-selected 10-h eating window for 14 days; water was allowed at all times. Participants completed a daily diary indicating when they began and stopped eating each day. To assess fatigue, participants completed the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and the Brief Fatigue Inventory (BFI) at pre- and post-intervention. We report mean±standard deviation and used a t-test to assess differences in pre- vs. post-intervention scores. Results: A total of 21 participants consented (20 breast cancer, 1 prostate cancer; 20 female; age 57.7±11.4 years; 1.6±1.1 years post-primary treatment). The study was feasible: 19/21 (90.5%) completed pre- and post-intervention assessments and daily diaries. It was also safe: there were two mild adverse events—one unlikely (insomnia) and one possibly related to the intervention (acute headache) and no severe adverse events. Most of the participants adhered to the intervention; 14/19 (73.7%) ate all of their food within a 10-h window at least 80% of the days, and 16/19 (84.2%) reported an average eating window ≤10 h. Fatigue scores improved a clinically meaningful degree for FACIT-F total score, FACIT-F fatigue subscale, and the BFI total score from pre- to post-intervention per established cutoffs (Table). Conclusions: Cancer survivors were willing and able to adhere to a two-week time-restricted eating intervention, and the intervention was safe. Also, fatigue was reduced with moderate to large effect sizes after two weeks of time-restricted eating. Based on our results, a follow-up randomized controlled trial to investigate time-restricted eating to alleviate cancer-related fatigue among cancer survivors is indicated.

The effects of geriatric assessment on oncologist-patient communication regarding functional status and physical performance in older adults with cancer: A secondary analysis of a 541-subject nationwide URCC NCORP (NCI Community Oncology Research Program) cluster randomized trial

12010

Background: Despite high prevalence of functional status (FS) and physical performance (PP) impairments among older adults with cancer, standardized assessments and interventions are not routinely used in oncology care. This study characterized how oncologist knowledge of Geriatric Assessment (GA) results influenced conversations and GA-guided recommendations addressing FS and PP concerns. Methods: Data were from a NCORP funded (UG1CA189961) nationwide cluster randomized controlled trial (ClinicalTrials.gov: NCT02107443; PI: Mohile), with inclusion criteria: age ≥70, stage III/IV solid tumor or lymphoma with palliative treatment intent, and ≥1 GA domain impairment. All subjects underwent baseline GA including standardized FS ([instrumental] activities of daily living) and PP (Timed Up and Go, Short Physical Performance Battery, Older Americans Resources and Services Physical Health scale, falls in past 6 months) measures. Oncologists in Intervention arm practices received full GA results and validated recommendations for each patient, while those in the usual care (UC) arm were only notified of depression or severe cognitive impairment. One clinical encounter per patient within 4 weeks of GA was audio-recorded, transcribed and blind coded using a priori content-analysis scheme to categorize conversations and oncologist response (dismissed, acknowledged, or addressed with recommendation) by GA domain. Frequencies, raw and adjusted (for site using generalized linear mixed models) proportions were compared using the Chi square test. Results: 541 patients (mean age: 77, range 70-96) were included. More FS and PP conversations occurred in Intervention (PP=532, FS=164) than UC (PP=183, FS=87) arm (p<.0001). The adjusted proportion of all patients having one or more FS or PP conversations reached 85.8% in the Intervention arm but only 58.6% in UC (p<.0001). Intervention oncologists were more likely to address FS and PP concerns than UC oncologists (42.6% vs 16.5%, p=0.0003), and to use referrals (Intervention=23.5%, UC=5.0%, p<.0001) or information (Intervention=22.3%, UC=3.8%, p=0.0006) to address them. Conclusions: Providing oncologists a GA report with recommended interventions enhances oncologist-patient communication regarding FS and PP-related concerns in older adults with advanced cancer. FS and PP-related issues were more likely to be addressed by those oncologists receiving the GA report, demonstrating the utility of GA as a tool in creating tailored interventions for FS and PP concerns. Our findings support use of GA as an important tool in caring for patients with impairments in physical performance and function. Funding: NIH/NCI UG1CA189961, T32CA102618.

Patterns and predictors of rehabilitation therapy among older patients with advanced cancer admitted to nursing homes: A SEER-Medicare analysis

6585

Background: Functional impairments affect > 40% of hospitalized patients (pts) with advanced cancer. After hospital discharge, about 20% of pts received rehabilitation (rehab) in nursing homes (NHs) to maintain functional independence. There is evidence from broad pt cohorts that Medicare Prospective Payment (PP) financially incentivizes NHs to provide extra rehab. This study examines rehab utilization among pts with advanced cancer admitted to NHs. Methods: The 2011-2016 SEER-Medicare data were linked with NH Minimum Data Set 3.0 data, which includes sociodemographic and clinical characteristics at admission. Study cohort included traditional Medicare pts with stage IV breast, lung, and colorectal cancer who were admitted to NHs after hospital discharge. Outcomes: total weekly rehab minutes of physical therapy, occupational therapy, and speech-language pathology; ultra-high rehab (≥720 min/wk); and rehab within 10 minutes of threshold (720-730 min/wk). Function and cognition were assessed by Activities of Daily Living (ADL) [7 domains; total score ranges 0 to 28 (higher = dependent)] and Cognitive Function Scale (intact, mild, moderate, severe impairment). Charlson Comorbidity Index (CCI) and survival from NH admission were computed. Generalized linear mixed models examined predictors of rehab outcomes adjusting for NH random effects. Results: A total of 7,453 pts were included (mean age 78.0, 85.8% White, 74.1% lung/ 16.1% colorectal/ 9.7% breast cancer; 76.1% had surgery, 8.9% had chemotherapy; mean CCI 1.9). The mean ADL score was 18.0, with on average 4.7 impairments; 40.2% reported ≥ mild cognitive impairment. Pts received on average 498 (SD = 245) min/wk rehab, but the distribution was trimodal. The number of pts who received 720-730 min/wk rehab was 2.7 times of the secondary peak at 500-510. From 2011-2016, the proportion of pts receiving ultra-high therapy (19.5%-48.4%) and within-threshold rehab (11.0%-32.0%) more than doubled. Only 5.9% of pts were documented on admission as having a life expectancy < 6 months, yet 32.1% and 74.3% died in 30 days and 6 months, respectively. Multivariable regressions indicate that compared to pts with ≥6 months’ expectancy, those with < 6 months’ expectancy received less rehab (β = -117.6), especially ultra-high rehab (odds ratio = 0.31). Pts with cognitive impairments received less rehab. Conclusions: Rehab utilization in older NH pts with advanced cancer mirrors patterns found in broader cohorts. Under PP, rehab minutes provided strongly followed payment thresholds. Over 5 years, more pts were provided 720-730 min/wk rehab, and 1/3 of these pts were at the end of life. Poor prognostication might contribute to the use of ultra-high rehab. Future work should evaluate whether the new Patient Driven Payment Model avoids excessive rehab use in patients with limited life expectancies.
