Updated systematic review of the effects of exercise on understudied health outcomes in cancer survivors

INTRODUCTION

The American College of Sports Medicine provided guidelines for exercise prescriptions in cancer survivors for specific cancer- and treatment-related health outcomes. However, there was insufficient evidence to generate exercise prescriptions for 10 health outcomes of cancer treatment. We sought to update the state of evidence.

METHODS

We conducted a systematic review of these 10 understudied health outcomes (bone health, sleep, cardiovascular function, chemotherapy-induced peripheral neuropathy (CIPN), cognitive function, falls and balance, nausea, pain, sexual function, and treatment tolerance) and provided an update of evidence.

RESULTS

While the evidence base for each outcome has increased, there remains insufficient evidence to generate exercise prescriptions. Common limitations observed across outcomes included: variability in type and quality of outcome measurement tools, variability in definitions of the health outcomes, a lack of phase III trials, and a majority of trials investigating breast or prostate cancer survivors only.

CONCLUSION

We identified progress in the field of exercise oncology for several understudied cancer- and treatment-related health outcomes. However, we were not able to generate exercise prescriptions due to continued insufficient evidence base. More work is needed to prescribe exercise as medicine for these understudied health outcomes, and our review highlights several strategies to aid in research acceleration within these areas of exercise oncology.

Physical function in older adults with and without a cancer history: Findings from the National Health and Aging Trends Study

BACKGROUND

Previous studies identified physical function limitations in older cancer survivors, but few have included objective measures and most focused on breast and prostate cancer survivors. The current study compared patient-reported and objective physical function measures between older adults with and without a cancer history.

METHODS

Our cross-sectional study used a nationally representative sample of community-dwelling, Medicare beneficiaries from the 2015 National Health and Aging Trends Study (n = 7495). Data collected included patient-reported physical function, including a composite physical capacity score and limitations in strength, mobility, and balance, and objectively measured physical performance metrics, including gait speed, five time sit-to-stand, tandem stand, and grip strength. All analyses were weighted to account for the complex sampling design.

RESULTS

Thirteen percent of participants (n = 829) reported a history of cancer, of which more than half (51%) reported a diagnosis other than breast or prostate cancer. In models adjusted for demographics and health history, older cancer survivors had lower Short Physical Performance Battery scores (unstandardized beta [B] = -0.36; 95% CI: -0.64, -0.08), slower gait speed (B = -0.03; 95% CI: -0.05, -0.01), reduced grip strength (B = -0.86; 95% CI: -1.44, -0.27), worse patient-reported composite physical capacity (B = -0.43; 95% CI: -0.67, -0.18) and patient-reported upper extremity strength (B = 1.27; 95% CI: 1.07, 1.50) compared to older adults without cancer. Additionally, the burden of physical function limitations was greater in women than in men, which may be explained by cancer type.

CONCLUSIONS

Our results extend studies in breast and prostate cancer to show worse objective and patient-reported physical function outcomes in older adults with a range of cancer types compared to those without a cancer history. Moreover, these burdens seem to disproportionately affect older adult women, underscoring the need for interventions to address functional limitations and prevent further health consequences of cancer and its treatment.

The Impact of Supervised, Individualized Exercise on Fatigue and Quality of Life during Adjuvant Radiotherapy for Breast Cancer

PURPOSE/OBJECTIVE(S)

Adjuvant radiation therapy in treatment for breast cancer has been shown to improve patient outcomes and reduce mortality rates. However, many patients experience debilitating fatigue as a result. Currently, there are limited treatment options for fatigue in cancer survivors. Options include pharmaceutical agents, psychological interventions, or nutrition strategies, all of which have limited efficacy. Exercise is recommended in survivorship care plans, but it not widely implemented beyond the use of generalized statements or resource guides given to patients. Therefore, the purpose of this study was the examine the impact of an individualized exercise program on fatigue, quality of life, and physical functioning during radiation therapy for breast cancer.

MATERIALS/METHODS

This multi-institutional prospective trial evaluated the effects of supervised, individualized exercise therapy in 422 patients undergoing adjuvant radiotherapy for breast cancer. Following a comprehensive fitness assessment and the completion of the Brief Fatigue Instrument (BFI) questionnaire, each participant participated in a 12-week individualized exercise program offered through Maple Tree Cancer Alliance. At its conclusion, the patients repeated the assessment and questionnaire.

RESULTS

Individualized exercise had a positive impact on fitness parameters and severity of fatigue. Specifically, cardiovascular endurance, muscular strength, muscular endurance, and flexibility all significantly improved following the exercise intervention (p<0.05). On average, patients fatigue levels decreased by 31.1% (P<0.01).

CONCLUSION

These results signify that fatigue levels are positively impacted by exercise among patients with breast cancer.

Patients with Nonalcoholic Steatohepatitis and Advanced Liver Disease Have the Lowest Cardiorespiratory Fitness

BACKGROUND & AIMS

Cardiorespiratory fitness and liver fibrosis are independently associated with poor outcomes in patients with nonalcoholic steatohepatitis (NASH), however, conflicting reports exist about their relationship. We aimed to better characterize the relationship between cardiorespiratory fitness and liver histology in a cross-sectional study of patients with biopsy-proven NASH.

METHODS

Participants aged 18-75 years completed VO2peak fitness assessment using symptom-limited graded exercise testing. Participants were compared by liver fibrosis stage and NAFLD Activity Score (NAS). Multivariable models were constructed to assess factors related to relative VO2peak, including liver fibrosis and NAS.

RESULTS

Thirty-five participants with mean age 48 ± 12 years and body mass index 33.5 ± 7.6 kg/m2 were enrolled. Seventy-four percent of participants were female and 49% had diabetes. A dose-dependent relationship was found between relative VO2peak and liver fibrosis. Relative VO2peak was significantly lower in participants with advanced fibrosis (F3 disease- 15.7 ± 5.3 vs. ≤ F2 disease- 20.7 ± 5.9 mL/kg/min, p = 0.027). NAS > 5 was also associated with lower relative VO2peak (22.6 ± 5.7 vs. 16.5 ± 5.1 mL/kg/min, p = 0.012) compared to NAS ≤ 5. With multivariable modeling, advanced fibrosis remained independently predictive of relative VO2peak while NAS trended towards significance.

DISCUSSION AND CONCLUSIONS

Advanced liver fibrosis is independently associated with cardiorespiratory fitness in patients with NASH. This may explain the incremental increase in mortality as liver fibrosis stage increases. Further research is needed to determine if exercise training can improve cardiorespiratory fitness across multiple stages of liver fibrosis and directly reduce morbidity and mortality in patients with NASH.

Dose Delays, Dose Reductions, and Relative Total Dose Intensity in Patients With Advanced Cancer Who Exercised During Neoadjuvant Chemotherapy Treatment

BACKGROUND

When it comes to chemotherapy, maintaining the dose and schedule of treatment are of vital importance, as clinical evidence suggests that dose intensity is associated with optimal treatment outcomes for various tumors. Yet, reduced dose intensity is a common method of mitigating the chemotherapy-induced side effects. Exercise has been shown to attenuate chemotherapy-related symptoms that frequently cluster together. Understanding this, we conducted a retrospective analysis in patients with advanced disease treated with adjuvant or neoadjuvant chemotherapy regimens and who completed exercise training during treatment.

METHODS

Data were collected retrospectively in a chart review of 184 patients, aged 18 years or older and treated for Stage IIIA-IV cancer. Data collection included baseline patient demographics and clinical characteristics, including age at diagnosis, cancer stage at initial diagnosis, chemotherapy regimen, and planned dose and schedule. Cancer types included brain (6.5%), breast (35.9%), colorectal (8.7%), non-Hodgkin's lymphoma (7.6%), Hodgkin's lymphoma (11.4%), non-small cell lung (16.8%), ovarian (10.9%), and pancreatic (2.2%). All patients completed at least 12 weeks of prescribed, individualized exercise. Each program included cardiovascular, resistance training, and flexibility components, under the supervision of a certified exercise oncology trainer once a week.

RESULTS

RDI was measured for each myelosuppressive agent in a regimen over the entire chemotherapy course and then averaged across the myelosuppressive agents in a regimen. An RDI of less than 85% was designated as the clinically meaningful threshold for reduction in RDI based on previously published studies.

CONCLUSIONS

A considerable proportion of patients across regimens had dose delays (18.3%-74.3%) and dose reductions (18.1%-84.6%). Between 12% and 83.9% of patients missed at least 1 dose of a myelosuppressive agent that was part of their standard regimen. Overall, 50.8% of patients received less than 85% of the RDI. In short, patients with advanced cancer and an exercise adherence above 84.3% saw fewer chemotherapy dose delays and dose reductions. These delays and reductions occurred significantly less frequently compared to the published norms in the sedentary population (P < .05).

Long-COVID and long-term cancer survivorship-Shared lessons and opportunities

As of 2022, close to 90 million persons in the United States, 243 million persons in Europe and 585 million worldwide have been infected with the novel SARS‐CoV‐2 (COVID‐19) virus and survived. Estimates vary but suggest that up to 50% may experience long‐term sequelae, termed ‘Long‐COVID’. While Long‐COVID is a new condition, the phenomenon of disabling long‐term effects following an illness requiring ongoing surveillance and management is not. In this commentary, we discuss how Long‐COVID parallels the experiences of long‐term cancer survivors, highlight shared challenges and offer opportunities to improve research and clinical care for both growing populations of patients as well as other long‐term chronic, disabling conditions.

Studying the implementation of exercise oncology interventions: a path forward

Introduction/Purpose

Extensive scientific evidence supports exercise benefits after a cancer diagnosis and the field now needs to focus on elucidating effective strategies for implementing exercise evidence-based interventions (EBIs) for cancer survivors.

Methods

This paper brings together three implementation efforts to describe pragmatic observations and strategies when implementing exercise oncology EBIs in non-research settings. From these projects, we report on common implementation barriers and facilitators. We then mapped these observations and strategies on to the phases and processes described in the Exploration, Preparation, Implementation, and Sustainment (EPIS) Framework.

Results

The first implementation project used key stakeholders' perspectives to develop a toolkit to implement BEAT Cancer (Better Exercise Adherence after Treatment for Cancer), a self-managed intervention led by fitness professionals. The second project adapted a physical activity behavior change intervention (Active Living after Cancer) for use in the broader community. The third project adapted an in-person exercise intervention in a community setting (Physical Activity and Lymphedema) into an out-patient rehabilitation setting, including home-based intervention elements (Strength After Breast Cancer). We retrospectively collated and operationalized the implementation strategies based on the Experts Recommending Implementation Change (ERIC) study. The most common implementation barriers were related to funding, organizational capacity and training, relationship building, patient referral, and engagement with patients.

Conclusions

These implementation strategies provide initial starting points for the implementation of exercise oncology EBIs in clinical and community settings while also serving as examples for future implementation research to advance the translation of exercise oncology evidence.

Epidemiology and impact of frailty in patients with atrial fibrillation in Europe

BACKGROUND

Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent.

OBJECTIVES

We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients.

METHODS

A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined.

RESULTS

Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty.

CONCLUSIONS

In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Cost-Savings Analysis of an Individualized Exercise Oncology Program in Early-Stage Breast Cancer Survivors: A Randomized Clinical Control Trial

PURPOSE

In an attempt to promote the integration of exercise oncology as a standard part of clinical practice, economic evaluations are warranted. Thus, the purpose of this study was to prospectively analyze cost savings of an individualized exercise oncology program when patients were randomly assigned.

METHODS

For this open-label, randomized, prospective, comparative clinical trial, patients with early-stage breast cancer (stage I-II) were randomly assigned into two groups: the control group (CG, n = 120) and the exercise training group (EX, n = 123). Patients in the exercise intervention group completed 12 weeks of prescribed, individualized exercise that aligned with ACSM exercise guidelines for cancer survivors. The CG received the current standard of care, which includes a resource guide with various options available to the cancer survivor.

RESULTS

In the EX group, all physical fitness measures significantly improved compared with baseline (P < .001), while remaining unchanged for the CG (P > .05). Patients in the CG had the highest total mean health care utilization across all measures (CG: $8,598 US dollars, compared with EX: $6,356 US dollars) for emergency visits, outpatient visits, and office-base visits that were not a part of their treatment plan. At baseline, the mean Eastern Cooperative Oncology Group (ECOG) scores did not significantly differ (P > .05); however, at follow-up, a larger proportion of the EX group had ECOG scores of 0 or 1, compared with the CG (P < .05). Finally, patient-reported outcomes were significantly higher in the exercise group, compared with the CG at the 12-week follow-up (P < .001).

CONCLUSION

A supervised, individualized 12-week exercise intervention led to significant improvements in fitness parameters and ECOG scores, as well as a decrease in unplanned health care utilization among early-stage breast cancer survivors.

NASHFit: A randomized controlled trial of an exercise training program to reduce clotting risk in patients with NASH

BACKGROUND AND AIMS

NASH is a common disease associated with increased rates of thromboembolism (TE). Although exercise training can lessen thrombotic risk in patients with vascular disease, whether similar findings are observed in patients with NASH is open for study.

APPROACH AND RESULTS

We conducted a 20-week randomized controlled clinical trial involving patients with biopsy-confirmed NASH. Patients were randomly assigned (2:1 ratio) to receive either an exercise training program or standard clinical care. The primary endpoint was change in plasminogen activator inhibitor 1 (PAI-1) level, an established thrombotic biomarker. Twenty-eight patients were randomly assigned (18 exercise training and 10 standard clinical care). PAI-1 level was significantly decreased by exercise training when compared to standard clinical care (-40 ± 100 vs. +70 ± 63 ng/ml; p = 0.02). Exercise training decreased MRI proton density fat fraction (MRI-PDFF; -4.7 ± 5.6 vs. 1.2 ± 2.8% absolute liver fat; p = 0.01); 40% of exercise subjects had a ≥30% relative reduction in MRI-PDFF (histological response threshold) compared to 13% for standard of care (p < 0.01). Exercise training improved fitness (VO₂ peak, +3.0 ± 5.6 vs. -1.8 ± 5.1 ml/kg/min; p = 0.05) in comparison to standard clinical care.

CONCLUSIONS

This clinical trial showed that, independent of weight loss or dietary change, exercise training resulted in a significantly greater decrease in thrombotic risk than standard clinical care in patients with NASH, in parallel with MRI-PDFF reduction and improvement in fitness. Future studies are required to determine whether exercise training can directly impact patient outcomes and lower rates of TE.

Transdisciplinary research in energetics and cancer (TREC) training program for early career investigators

11031

Background: Given the rising prevalence of obesity, poor diet and physical inactivity, known in combination as “energy balance” or “energetics”, as well as their associations with cancer incidence and mortality, innovative research, clinical care and training of scientists are needed to lower the prevalence of these risk factors and in turn, lower cancer incidence and mortality rates. Methods: With NCI support (R25CA203650) from 2016-2021, we developed and offered an annual one-week, in-residence Transdisciplinary Research in Energetics and Cancer (TREC) Training workshop, followed by a yearlong mentoring program, that focused on energy balance and cancer research across the cancer control continuum. Results: We recruited, educated, trained and mentored 123 early career investigators (TREC Fellows) from 64 different institutions and from diverse academic backgrounds (i.e., 20% basic, 33% clinical and 47% population sciences) in transdisciplinary research in energetics and cancer. Fellows accepted to the TREC Training Program worked with more than 20 expert international TREC Faculty on developing grant applications and original research toward key gaps in energy balance and cancer research. TREC Fellows have published over 270 manuscripts in peer-reviewed journals, with at least 62 published manuscripts including the TREC Fellow as first or senior author and including a TREC Faculty and/or Fellow as co-author. Since completing the Program, TREC Fellows have received at least 31 extramural grants, as principal investigator. Building upon the strengths of the previous five years, we were awarded a competitive renewal to continue the TREC Training Program through 2026. TREC Training program goals are: (1) to continue to offer a TREC Training Program for ̃100 academically diverse early career investigators including a 5-day in-residence workshop focused on the Fellows research, networking, mentoring and professional development; (2) to evaluate the TREC Training Program and track TREC Fellows career development; and (3) to disseminate the TREC Training sessions, webinars and newsletter to the broader community of investigators. Conclusions: To our knowledge, no other in-residence training program exists that focuses on energetics and cancer research. Our vision is to continue the TREC mission of training scientists and clinicians to develop a cadre of well-trained, diverse researchers. The overall impact of this transdisciplinary training course will be defined by the degree to which TREC Fellows produce innovative research approaches and discoveries, thereby accelerating the dissemination and implementation of evidence-based approaches into everyday practice and patient care and improving the health of the population at risk for cancer as well as cancer survivors.

Nurse AMIE: Addressing symptoms in rural patients with advanced cancer

TPS12148

Background: Prior research has shown that monitoring symptoms in advanced cancer patients may provide a survival benefit. Monitoring is a labor-intensive process that requires nursing staff response and visiting a medical office. This may be more challenging in rural areas, given staffing challenges and distances traveled for care. Lower density of supportive care services has been documented in rural as compared to urban settings in Pennsylvania and West Virginia. We have developed a computer tablet-based supportive care program, called Nurse AMIE, and are investigating its use in symptom management among cancer survivors. Our hypothesis is that a tablet-based supportive care program can improve overall survival of advanced cancer patients in rural Pennsylvania and West Virginia. Methods: This randomized controlled trial will recruit 344 patients residing in a rural county or zip code (RUCC 4-9 or RUCA 4-10) in Pennsylvania or West Virginia, who receive treatment for stage III-IV cancer, are 18 years or older, ECOG 0-3, are fluent in written and spoken English, have sufficient vision/hearing to interact with a computer tablet and staff, and have a clinician-defined life expectancy of 6 months or more. Exclusion criteria: patients on active treatment or behavioral or supportive care trials, or with medical or psychiatric conditions that would impair ability to test study hypotheses. Patients will be randomized on a 1:1 basis to receive either Nurse AMIE or a binder with written supportive care materials. Intervention participants will be asked to log into Nurse AMIE daily, where they will interact with a nurse avatar and answer symptom questions (focusing on sleep, fatigue, pain, and distress). They will receive an empathic response to symptoms and be offered evidence based, guideline concordant self-care interventions to address symptoms (including exercise, nutrition, guided meditation, cognitive behavioral therapy videos, and soothing music). Once weekly, patients will answer 21 questions from the Pro-CTCAE survey. All symptom data will be loaded into a dashboard reviewed daily by study staff. Pain or distress scores of 7+ (out of 10) will be communicated to the care team through the EMR. The trial is powered to detect a 19% difference in overall survival at 2 years follow-up (based on Denis et al JAMA 2019). Secondary outcomes include incidence of chemotherapy toxicities, patient reported outcomes, and cost effectiveness. Enrollment is anticipated to start in March 2022. A community advisory board of 12 cancer patients and stakeholders meet on a quarterly basis to provide feedback on study activities (e.g., usability testing, adaptations, overall implementation) and ensure the project responds to the needs and preferences of rural cancer patients in Pennsylvania and West Virginia. NIH R01-CA254659. Clinical trial information: NCT05221606.

Primäre synoviale Chondromatose

Hintergrund

Die primäre synoviale Chondromatose (SC) ist eine seltene Erkrankung der Synovialmembran unklarer Ätiologie. Der aktuelle Wissensstand zu dieser Erkrankung soll in einer kurzen Übersicht dargestellt werden.

Methoden

Übersichtsarbeiten und rezente Fallberichte zur SC wurden systematisch ausgewertet und mit Daten eigener Fälle in Kontext gesetzt.

Ergebnisse

Auf Grund neuer genomischer Daten wird die SC als benigne Neoplasie eingestuft. In 60 % der Fälle liegen Mutationen im Fibronektin-1-Gen (FN1) und/oder im Gen für den Activin-A-Typ-II-Rezeptor (ACVR2A) vor. Diagnoseweisend ist die Magnetresonanztomographie (MRT) und die meist arthroskopische Biopsie der Synovia. An einem Fallbeispiel soll gezeigt werden, dass die Knorpelaggregate der SC radiologisch nicht immer schattengebend sein müssen. Differenzialdiagnostisch kommen Monarthritiden anderer Ursachen, andere Gelenk- und Muskelerkrankungen mit Mineralisierung sowie weitere von der Synovialmembran ausgehende Erkrankungen in Betracht. Die Entartungsrate liegt bei 2–4 %. Therapeutisch hat sich in den letzten Jahren das arthroskopische Vorgehen durchgesetzt, das an die Ausdehnung der Erkrankung adaptiert wird.

Schlussfolgerung

Genomische Untersuchungen sowie Fallserien und Fallberichte aus jüngerer Zeit werfen ein neues Licht auf die SC. Therapeutisch wird in jüngeren Arbeiten überwiegend arthroskopisch vorgegangen.

Serial Mediation Roles of Perceived Stress and Depressive Symptoms in the Association Between Sleep Quality and Life Satisfaction Among Middle-Aged American Adults

In this study, we used data from the second wave of Midlife in the United States (MIDUS) Study, MIDUS Biomarkers and MIDUS 3. We applied the serial mediation model to explore the serial mediating effects of perceived stress and depressive symptoms on the relationship between sleep quality and life satisfaction. A total of 945 participants were included in our study. The total indirect effect of sleep quality on life satisfaction through perceived stress, depressive symptoms and the combination of perceived stress and depressive symptoms accounted for within the overall model was 45.5%. At the intervention level, programs designed to improve the level of life satisfaction among adults should focus on perceived stress and depressive symptoms. The prevention of perceived stress and depression contributes to improving life satisfaction and wellbeing. The serial mediation results should be confirmed by further longitudinal study.

Survey of lower urinary tract symptoms in United States women using the new lower urinary tract dysfunction research Network-Symptom Index 29 (LURN-SI-29) and a national research registry

PURPOSE

An online bladder health survey was administered to national registry volunteers to: (1) determine the feasibility of using ResearchMatch for studying lower urinary tract symptoms (LUTS); (2) pilot the new, comprehensive Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN-SI-29) and determine its ability to detect known associations with LUTS; and (3) explore novel areas of bladder health in community-based women.

METHODS

A cross-sectional web-based survey was administered to a random sample of ResearchMatch adult female, transgender and non-binary volunteers. Participant demographics, health characteristics, the LURN-SI-29, and LUTS-related experiences were collected.

RESULTS

A total of 1725 ReseachMatch volunteers with a mean age of 44.0 years completed the study and were eligible for the analysis. Participants were primarily white, cisgendered, highly educated, nulliparous, and premenopausal. The median LURN-SI-29 score was 17 (interquartile range: 11-26). More than half the sample reported urinary urgency (71.0%), nocturia (65.7%), and stress incontinence (52.3%) a "few times" or more in the last 7 days. Approximately half reported sensation of incomplete bladder emptying (49.6%) with one-third reporting urgency incontinence (37.6%); notably, 52.6% of respondents reported being at least "somewhat" bothered by LUTS. LURN-SI-29 scores increased with age, body mass index, decrements in self-reported health, medical comorbidity, parity, menopausal status, and urinary symptom bother, providing evidence of convergent validity. LURN-SI-29 scores varied by race and education, with the lowest scores in Asian and highly educated women.

CONCLUSION

Overall, the prevalence and spectrum of LUTS in an online research registry of women volunteers were high and comparable to other population-based samples. The new LURN-SI-29 demonstrated its ability to detect expected associations with demographic and health characteristics in a nonclinical population.

Adapting an Evidence-based Physical Activity Program for The REJOIN Trial for Older Breast Cancer Survivors

Purpose: Physical activity (PA) is a recommended part of breast cancer survivorship. PA promotes survival and mitigates symptoms in older breast cancer survivors (BCS), especially in reducing joint pain associated with adjuvant hormonal treatment. The purpose of this report is to describe adaptations to Fit & Strong!, an evidence-based curriculum, to meet the needs of older BCS. Methods: First, we reviewed all educational materials with scientific experts, including specialists in breast and exercise oncology. Next, we conducted semi-structured phone interviews with 3 BCS for an in-depth review of educational materials for the trial. All interviews were recorded and transcribed. Constant comparative analysis was used to identify themes and specify required technical changes. Subsequently, we recruited 3 new BCS to pre-test adapted materials and exercise sessions, complete a follow-up interview to refine our final product and rate acceptability with older BCS. Results: Overall, BCS found the materials and experience very acceptable (mean score of 9.5/10). Content changes included simplifying exercise instructions, prioritizing trial-specific content and updating photographs to be more age-appropriate. Due to COVID, the pre-test activity was conducted by Zoom and participants were given additional time and coaching to participate using this technology. BCS said they would prefer to exercise in person but reported the remote experience as very satisfactory. Conclusion: Our multi-step adaptation process provided an acceptable intervention to meet the needs of older BCS. Lessons learned will be applied to the forthcoming clinical trial, which will also be conducted remotely to maximize safety and access.

Breaking Down Barriers to Physical Activity in Patients with Nonalcoholic Fatty Liver Disease

BACKGROUND

Lifestyle changes, including physical activity, are the cornerstones of the treatment of nonalcoholic fatty liver disease (NAFLD). For unclear reasons, most NAFLD patients do not achieve the recommended amount of weekly activity.

AIMS

Our aim was to measure perceived barriers to physical activity and enablers to exercise intervention.

METHODS

Consecutive subjects aged 18-70 with NAFLD were prospectively enrolled. An exercise motivation questionnaire was administered to assess current behaviors and perceived barriers.

RESULTS

Eighty-seven subjects (60% female) were enrolled with mean age 52 years and mean body mass index (BMI) 34.5 kg/m². Metabolic comorbidities were common: 49% had hyperlipidemia, 42% hypertension, and 40% diabetes. The majority (75%) did not achieve ≥ 150 min/week of physical activity. Ninety-one percent agreed that activity was important in improving NAFLD; 88% desired to be more active. Lack of exercise resources and education from treating provider (47%), physical discomfort during exercise (44%), and time constraints (32%) were the most common barriers. Rates of fitness tracker (34%), gym (33%), exercise program (33%), and personal trainer (17%) use were low.

CONCLUSIONS

While nearly all subjects with NAFLD identify physical activity to be important and desire to be more active, only a few meet activity recommendations. This discordance is due to a perceived lack of resources and education, physical discomfort, and time constraints. Better understanding of these barriers and behaviors are important to improve morbidity and mortality in NAFLD. Future behavioral research removing the identified barriers is of great importance to global public health and should be prioritized.

Transdisciplinary Research in Energetics and Cancer early career investigator training program: first year results

Energy imbalance increases cancer burden by increasing cancer risk and mortality. Training early career investigators on conducting impactful energy balance and cancer research is needed. We developed a Transdisciplinary Research in Energetics and Cancer (TREC) Training Program for early career investigators. This analysis examined program satisfaction, knowledge gained, publications, and awards among Year 1 participants (i.e., fellows). The program consists of an in-person course, followed by 1 year of mentorship. Faculty and fellows completed precourse and postcourse surveys. Following the mentorship period, we surveyed fellows for TREC-related research productivity, including publications and grant funding attributed to the program. Twenty fellows were accepted into the program: 3 basic, 7 clinical, and 10 population scientists. Sixteen fellows were junior faculty and four were postdoctoral fellows. The course included ~50 lectures, small group sessions, and faculty-fellow sessions. 96.7% of attendees rated the course in the highest categories of "good/very good." Knowledge significantly improved in 37 of 39 research competencies (94.8%). In the 18 months following the course, fellows published 25 manuscripts, with 3 published in journals with impact factor ≥10. Nineteen grants were funded to TREC fellows (i.e., 7 National Institutes of Health awards, 2 American Cancer Society [ACS] awards, and 10 foundation/pilot awards), and 7 fellows received career promotions. The program's impact will be defined by the degree to which TREC fellows produce discoveries that could improve the health of populations at risk for and/or surviving cancer. Upon the conclusion of our fifth year in 2021, we will publicly disseminate the program material.

Increased Duration of Exercise Decreases Rate of Nonresponse to Exercise but May Not Decrease Risk for Cancer Mortality

INTRODUCTION

Previous studies have observed an inverse relationship between exercise and breast cancer risk. However, there is interindividual variability in response to exercise training interventions. We investigated whether increasing the dose of aerobic exercise (150 or 300 min·wk-1), while keeping intensity of exercise constant (70%-80% HRmax), decreases the number of exercise nonresponders and further decreases associated risk for cancer mortality in our study population of women genetically predisposed for breast cancer.

METHODS

Healthy premenopausal women at elevated risk of breast cancer were randomized into control (<75 min·wk-1, n = 47), low-dose exercise (150 min·wk-1, n = 39), and high-dose exercise groups (300 min·wk-1, n = 39) for approximately 6 months. We assessed 1) clinical effectiveness (CE), defined as an improvement in predicted V˙O2max of ≥1 mL·kg-1·min-1, and twice the typical error (2× TE) of V˙O2max as thresholds to classify exercise "nonresponders"; 2) CE and 2× TE relative to exercise adherence levels; and 3) related changes in V˙O2max to predicted cancer mortality risk.

RESULTS

After our 6-month intervention, we observed that 23.5% of women in the low-dose group and 5.6% of women in the high-dose group were clinical nonresponders (P = 0.04). Clinical nonresponder status was independent of adherence level. Associated reduction in risk for cancer mortality was observed among 87.2% of women in the low-dose group and 94.9% in the high-dose group (P = 0.43).

CONCLUSION

Increasing volume (not intensity) of exercise via time spent exercising significantly decreases the number of "nonresponders." True nonresponders were observed as some women did not improve their fitness capacity despite high exercise adherence levels. Lastly, it appears 150 min·wk-1 is sufficient to decrease the predicted risk of cancer mortality.

Overview of REJOIN: A Clinical Trial to Use Exercise to Relieve Joint Pain in Older Breast Cancer Survivors

Aromatase Inhibitors (AIs) are recommended for survival in hormone-sensitive breast cancer survivors, yet are underutilized, especially in older survivors. Joint pain is a prevalent AI-related symptom that is associated with low adherence. The aims for this randomized clinical trial (n=76) are to: 1) adapt a self-management (exercise + education) intervention for older survivors planning to take AIs; 2) Test the effect of a pilot intervention on arthralgia; and 3) Test its effect on AI medication adherence behaviors. We will adapt a program for seniors that includes bi-weekly 60-minute sessions of supervised exercise plus 30 minutes of education. The 16-week program includes: 8-weeks in person plus 8-weeks at home with phone counseling. We will conduct geriatric plus baseline assessment of exercise, joint pain, and AI adherence (repeated 4, 6 and 12 months). More research with geriatric survivors is required to address treatment needs and to promote survival. Part of a symposium sponsored by the Cancer and Aging Interest Group.

Standardization of lower extremity quantitative lymphedema measurements and associated patient-reported outcomes in gynecologic cancers

Practice changing standardization of lower extremity lymphedema quantitative measurements with integrated patient reported outcomes will likely refine and redefine the optimal risk-reduction strategies to diminish the devastating limb-related dysfunction and morbidity associated with treatment of gynecologic cancers. The National Cancer Institute (NCI), Division of Cancer Prevention brought together a diverse group of cancer treatment, therapy and patient reported outcomes experts to discuss the current state-of-the-science in lymphedema evaluation with the potential goal of incorporating new strategies for optimal evaluation of lymphedema in future developing gynecologic clinical trials.

Exercise Attenuates Ribosomal Protein Six Phosphorylation in Fatty Liver Disease

INTRODUCTION

Nonalcoholic fatty liver disease (NAFLD) is the leading cause of liver disease worldwide. Nonalcoholic steatohepatitis (NASH), is a more severe type of NAFLD. Exercise improves NASH, by reversing steatosis, and may arrest fibrosis. However, the mechanisms underlying these interactions are unknown. AMP-activated protein kinase (AMPK) is a fuel-sensing enzyme that is activated by energy stress. Mammalian target of rapamycin in complex 1 (mTORC1) is a nutrient sensor that regulates protein synthesis. In NASH, AMPK activity is low and mTORC1 is high. In healthy persons, exercise activates AMPK and suppresses mTORC1. We examined the effects of exercise on hepatic ribosomal protein S6 phosphorylation, a downstream target of AMPK and mTORC1 in patients with NASH.

METHODS

Three subjects with biopsy-proven NASH underwent a structured, 20-week aerobic exercise intervention, five-days a week for 30-min at a moderate intensity (40-55% of VO2max). Immunofluorescence staining for rpS6 phosphorylation in hepatic tissue was quantified by ImageJ software.

RESULTS

Following 20-weeks of aerobic exercise, rpS6 levels were significantly attenuated (3.9 ± 1.9 pre-exercise vs. 1.4 +/0.4 post-exercise, p = 0.04).

CONCLUSIONS

These findings suggest exercise modulates the AMPK/mTORC1 pathway in patients with NASH and may guide the design of future studies into the mechanism of how exercise improves NASH and possibly reverses fibrosis.

Nonalcoholic steatohepatitis Fitness Intervention in Thrombosis (NASHFit): Study protocol for a randomized controlled trial of a supervised aerobic exercise program to reduce elevated clotting risk in patients with NASH

Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease worldwide affecting upwards of one third the global population. For reasons not fully understood, individuals with NAFLD and its more severe variant, nonalcoholic steatohepatitis (NASH), are at increased risk for venous thromboembolism which significantly increases morbidity and mortality. Lifestyle changes centering around exercise training are the mainstay of treatment for NAFLD/NASH. While exercise training can lessen venous thromboembolic risk in healthy persons and those with cardiovascular disease, whether or not this benefit is seen in patients with NAFLD/NASH remains unknown. In order to better understand how exercise training impacts thrombosis risk in NAFLD, we present the design of a thirty-two week randomized controlled clinical trial of 42 sedentary subjects age 18-69 with biopsy proven NASH. The main aim is to determine the impact of an aerobic exercise training program on the abnormal hemostatic system unique to NAFLD/NASH. The main outcome is change in plasminogen activator inhibitor one level, an established marker for venous thromboembolism. Secondary outcomes include body composition, cardiorespiratory fitness, control of comorbid metabolic conditions (e.g., obesity, hypertension, hyperlipidemia, diabetes), dietary composition, health related quality of life, liver enzymes and histology, NAFLD/NASH disease activity (e.g., biomarkers, clinical decision aids), microbiome, other markers of hemostasis, and PNPLA3 gene expression. The study represents the first clinical trial of an exercise training program to reduce elevated clotting risk in subjects with NAFLD/NASH.

DETERMINANTS OF LEISURE-TIME PHYSICAL ACTIVITY IN OLDER, RURAL CANCER SURVIVORS IN CENTRAL PENNSYLVANIA

This study explored social and environmental determinants of leisure-time physical activity (LTPA) in cancer survivors (CS) residing in Central Pennsylvania, a largely rural region. Rural CS completed questionnaires assessing LTPA, social support (SS) for LTPA, home and neighborhood environments for LTPA. Logistic regression models were used to assess associations with being active/inactive. Participants (n=219) were categorized as mature survivors (<75 years, 80.7%) or elderly survivors (>=75 years, 19.3%). Only 28.2% of elderly survivors reported meeting LTPA guidelines compared to 45.6% of mature survivors. Survivors reporting SS for LTPA were 10% more likely to active than those who did not have SS (OR=1.1, CI 1-1.1). Mature survivors that reported environmental support (home: OR=1.2: CI 1-1.3; neighborhood: OR=1.8, CI: 1-3.2) were more likely to be active than those without strong environmental support. Creating more supportive environments to foster LTPA in elderly survivors in rural areas is a key priority for future research.

Abstract LB-164: Transdisciplinary research in energetics and cancer (TREC) early career investigator training program: First year results

Purpose: Obesity, poor diet and physical inactivity increase the burden of cancer by increasing risk of incident cancer, mortality, and long term adverse treatment effects. It is critical that scientists receive training in conducting rigorous and impactful energy balance and cancer research. To address this need, we developed an annual one-week, in residence NCI-R25-funded Transdisciplinary Research in Energetics and Cancer (TREC) Training Course for early career investigators in basic, clinical and population sciences. This analysis examined the impact of the TREC Training Program on course satisfaction, knowledge gained, publications and awards among TREC Year 1 program participants (i.e., TREC Fellows).

Methods: The TREC program consists of two components: an intensive, in-person, one-week Course, followed by a one-year TREC mentorship program. TREC Faculty are comprised of a TD team of ~20 international expert faculty members. TREC Faculty and Fellows completed surveys before and immediately after the course. The Wilcoxon Signed Rank Test was used to determine course-related changes in knowledge and skills. At the end of the one-year mentorship period, a survey was sent inquiring about TREC-related research productivity and collaborations. Number of publications and grant-funding between June 2017 and December 2018 was compiled and summarized for the 20 TREC Fellows participating in the inaugural TREC course.

Results: Information about the program was shared with ~30 organizations, resulting in 77 applications for the inaugural course. Twenty TREC Fellows completed the program, including three basic, seven clinical, and 10 population scientists. Sixteen of the TREC fellows were junior faculty and four were postdoctoral fellows. The 5-day course included over 50 lectures, small-group breakouts and Faculty-Fellow sessions. Attendees rated the course as very high, with an average 96.7% of responses scoring in the top two categories of “good” or “very good”. Knowledge related to conducting energy balance and cancer research significantly improved in 37 out of 39 competencies (94.8%). Between the end of the TREC Year 1 program in June 2017 and December 2018, TREC Year 1 Fellows published 20 manuscripts, with 15 co-authored with other TREC Fellows and/or Faculty. Fifteen % of manuscripts were published in journals with an impact factor &gt; 10. A total of 19 grant applications were funded to TREC Fellows (i.e., five NIH awards, three ACS awards, three foundation awards, and eight internal pilot awards). Seven TREC Fellows were appointed or promoted in academic positions.

Conclusion: The overall impact of the TREC Program will be defined by the degree to which TREC Fellows produce innovative research approaches and discoveries that could improve the health of populations at risk for cancer as well as cancer survivors. Upon completion of the 5th year of the TREC Training Program in 2021, we will disseminate the TREC Training Program material for adoption by the broader research and clinical community.

Change in Inflammatory Biomarkers and Adipose Tissue in BRCA1/2+ Breast Cancer Survivors Following a Yearlong Lifestyle Modification Program

Breast cancer survivors who carry a genetic mutation for one of the BRCA genes often undergo surgically induced menopause a decade or more before the usual age of natural menopause. These women are at elevated risk for multiple negative health outcomes, including metabolic diseases, heart disease, and cancer recurrence. Effects of a 12-month commercially available web-based lifestyle program (Precision Nutrition) were tested on body composition and markers of inflammation in a randomized controlled trial. Participants (N = 35) were BRCA1/2⁺, breast cancer survivors, and had completed surgically induced menopause at age <45 years. Dual-energy X-ray absorptiometry was used to quantify body composition. Fasting blood samples were used to assay insulin, IL1β, IL6, IL8, and TNFα. At baseline, we observed relationships between insulin, TNFα, and IL6, and between biomarkers and adiposity. Insulin and subcutaneous adipose tissue levels significantly decreased following the intervention compared with the change in the control group. Compared with baseline, TNFα and total adipose tissue levels decreased significantly in the intervention group. The percent change in insulin levels was moderately correlated with the percent change in subcutaneous adipose tissue (r = 0.33). Change in adiposity was not related to change in TNFα or IL6. Women in the intervention group decreased levels of subcutaneous, but not visceral, adipose tissue. The change in subcutaneous adipose tissue was the main driver of change in insulin levels for the women in the intervention group. However, the change in body composition achieved by the Precision Nutrition program was not sufficient to alter biomarker levels of inflammation. Cancer Prev Res; 11(9); 545-50. ©2018 AACR.

Comprehensive pharmaceutical care to prevent drug-related readmissions of dependent-living elderly patients: a randomized controlled trial

BACKGROUND

Elderly patients are vulnerable to adverse drug reactions (ADRs). Drug-related readmissions (DRRs) can be a major consequence of ADR. Therefore, this study aimed to investigate the effects of a ward-based, comprehensive pharmaceutical care service on the occurrence of DRRs as the endpoint in dependent-living elderly patients.

METHODS

A randomized, controlled trial was performed at a German University Hospital. Patients fulfilling the following criteria were eligible: admission to a cooperating ward, existing drug therapy at admission, 65 years of age and older, home-care or nursing home residents in ambulatory care, and a minimum hospital stay of three days. Patients received either standard care (control group) or pharmaceutical care (intervention group). Follow-up consultations were conducted for each patient at 1, 8, 26, and 52 weeks after discharge. The time to DRR was defined as the primary outcome measure and was analysed using the log-rank test. The Cox-proportional hazard model was used for risk factor analysis.

RESULTS

Sixty patients (n = 31 intervention group, n = 29 control group) participated in the study. For patients in the intervention group, the median time to DRR was prolonged; however, the level of statistical significance was not reached (log-rank test P = 0.068; HR = 3.28, P = 0.086). When the risk factors 'age' or 'length of stay on the ward' were added to the Cox proportional hazard model, patients in the control group exhibited a significantly higher risk of experiencing a DRR than patients of the intervention group (HR = 4.62; P = 0.028 including age and HR = 5.76; P = 0.033 including length of stay on the ward).

CONCLUSIONS

Our findings demonstrate the successful implementation of ward-based, comprehensive pharmaceutical care for dependent-living elderly. Despite a low participation rate, which led to an underpowered study, the results provide a preliminary efficacy signal and effect size estimates to power a definitive trial.

Dysregulation of lysophosphatidic acids in multiple sclerosis and autoimmune encephalomyelitis

Abstract

Bioactive lipids contribute to the pathophysiology of multiple sclerosis. Here, we show that lysophosphatidic acids (LPAs) are dysregulated in multiple sclerosis (MS) and are functionally relevant in this disease. LPAs and autotaxin, the major enzyme producing extracellular LPAs, were analyzed in serum and cerebrospinal fluid in a cross-sectional population of MS patients and were compared with respective data from mice in the experimental autoimmune encephalomyelitis (EAE) model, spontaneous EAE in TCR¹⁶⁴⁰ mice, and EAE in Lpar2^-/- mice. Serum LPAs were reduced in MS and EAE whereas spinal cord LPAs in TCR¹⁶⁴⁰ mice increased during the ‘symptom-free’ intervals, i.e. on resolution of inflammation during recovery hence possibly pointing to positive effects of brain LPAs during remyelination as suggested in previous studies. Peripheral LPAs mildly re-raised during relapses but further dropped in refractory relapses. The peripheral loss led to a redistribution of immune cells from the spleen to the spinal cord, suggesting defects of lymphocyte homing. In support, LPAR2 positive T-cells were reduced in EAE and the disease was intensified in Lpar2 deficient mice. Further, treatment with an LPAR2 agonist reduced clinical signs of relapsing-remitting EAE suggesting that the LPAR2 agonist partially compensated the endogenous loss of LPAs and implicating LPA signaling as a novel treatment approach.

Exercise Among Women With Ovarian Cancer: A Feasibility and Pre-/Post-Test Exploratory Pilot Study

PURPOSE/OBJECTIVES

To establish the feasibility and acceptability of completing a higher dose of the planned physical activity volume among women with ovarian cancer, including those undergoing active treatment. 
.

DESIGN

A pre-/post-test exercise intervention. All participants were asked to complete 225 minutes per week of physical activity for 26 weeks. Multiple supports were provided, including exercise DVDs, self-reported logs, and an objective physical activity tracker (Fitbit®).
.

SETTING

Home-based exercise intervention with in-person training and telephone follow-ups.
.

SAMPLE

10 women with ovarian cancer who were treated within Penn Medicine in Philadelphia, Pennsylvania.
.

METHODS

Home-based, in-person exercise counseling was provided by an exercise trainer weekly for the first six weeks and then monthly for a total of 26 weeks. Weekly follow-up telephone calls were used to assess exercise adherence and barriers to completing exercise, review symptom changes, and provide behavioral support. 
.

MAIN RESEARCH VARIABLES

Feasibility and acceptability.
.

FINDINGS

Eight participants completed the study and achieved at least 80% of the prescribed exercise dose. Five participants were undergoing chemotherapy simultaneously. Participants experienced no adverse events during the 26-week intervention. Compared to baseline, average steps increased by 1,593 per day and moderate-intensity physical activity increased by 15 minutes per day. 
.

CONCLUSIONS

A 225-minutes-per-week exercise program is feasible and acceptable in a population of patients with ovarian cancer. Participants significantly improved their physical activity during the 26-week intervention.
.

IMPLICATIONS FOR NURSING

The findings suggest that nursing professionals could recommend that women with ovarian cancer exercise 225 minutes per week regardless of cancer and/or treatment trajectory. For those experiencing aches and pains, behavioral supports and suggestions of a lower exercise dose are needed to maintain physical activity.

Urinary incontinence and other pelvic floor disorders after radiation therapy in endometrial cancer survivors

OBJECTIVE

To investigate radiation therapy as a risk factor for urinary or fecal incontinence, pelvic organ prolapse, and sexual dysfunction in endometrial cancer survivors.

STUDY DESIGN

We performed a retrospective cohort study of endometrial cancer survivors. Data were collected using a mailed survey and the medical record. Validated questionnaires were used to generate rates of urinary incontinence and other pelvic floor disorders. The incidence rates of pelvic floor disorders were compared across groups with different exposures to radiation.

RESULTS

Of the 149 endometrial cancer survivors, 41% received radiation therapy. Fifty-one percent of women reported urine leakage. The rates of urinary incontinence in women exposed and not exposed to vaginal brachytherapy (VBT) or whole-pelvis radiation were 48% and 58%, respectively (p=0.47). The incidence of fecal incontinence did not differ between groups, but the score for overall sexual function was significantly higher in women who did not undergo radiation therapy. On multivariable analysis, significant risk factors for urinary incontinence were age (AOR 1.06 95% CI 1.02, 1.10) and BMI (AOR 1.07 95% CI 1.02, 1.11), but treatment with radiation was not significantly associated with urinary incontinence, or fecal incontinence (p>0.05). Age, BMI, and radiation exposure were independent predictors of decreased sexual function score (p<0.01).

CONCLUSION

Local or regional radiation is not associated with urinary or fecal incontinence, but may contribute to sexual dysfunction in endometrial cancer survivors.
