Exercise is medicine in oncology: Engaging clinicians to help patients move through cancer.

Multiple organizations around the world have issued evidence-based exercise guidance for patients with cancer and cancer survivors. Recently, the American College of Sports Medicine has updated its exercise guidance for cancer prevention as well as for the prevention and treatment of a variety of cancer health-related outcomes (eg, fatigue, anxiety, depression, function, and quality of life). Despite these guidelines, the majority of people living with and beyond cancer are not regularly physically active. Among the reasons for this is a lack of clarity on the part of those who work in oncology clinical settings of their role in assessing, advising, and referring patients to exercise. The authors propose using the American College of Sports Medicine's Exercise Is Medicine initiative to address this practice gap. The simple proposal is for clinicians to assess, advise, and refer patients to either home-based or community-based exercise or for further evaluation and intervention in outpatient rehabilitation. To do this will require care coordination with appropriate professionals as well as change in the behaviors of clinicians, patients, and those who deliver the rehabilitation and exercise programming. Behavior change is one of many challenges to enacting the proposed practice changes. Other implementation challenges include capacity for triage and referral, the need for a program registry, costs and compensation, and workforce development. In conclusion, there is a call to action for key stakeholders to create the infrastructure and cultural adaptations needed so that all people living with and beyond cancer can be as active as is possible for them.

NCCN Guidelines® Insights: Survivorship, Version 1.2023.

The NCCN Guidelines for Survivorship are intended to help healthcare professionals address the complex and varied needs of cancer survivors. The NCCN Guidelines provide screening, evaluation, and treatment recommendations for psychosocial and physical problems resulting from adult-onset cancer and its treatment; recommendations to help promote healthy behaviors and immunizations in survivors; and a framework for care coordination. These NCCN Guidelines Insights summarize recent guideline updates and panel discussions pertaining to sleep disorders, fatigue, and cognitive function in cancer survivors.

Reduced Cancer-Related Fatigue after Tablet-Based Exercise Education for Patients.

AIM: Exercise can be an effective treatment for cancer-related fatigue, but exercise is not prescribed for many cancer patients. Our specific aim was to compare usual care and a tablet-based fatigue education and prescription program for effects on level of fatigue (primary outcome) and satisfaction with fatigue and amount of exercise (secondary outcomes). METHODS: In a four-week pretest/posttest randomized study, 279 patients with cancer completed a touch screen fatigue assessment and daily paper-based activity logs. The experimental group also had access to FatigueUCope, a tablet-based multimedia education intervention focused on exercise as therapy for fatigue. RESULTS: In total, 94% of intervention group accessed FatigueUCope. Controlling for baseline fatigue, compared to the usual-care group, the experimental group reported lower fatigue scores (P = .02). Neither satisfaction with fatigue nor exercise level was significantly different between groups, but not all activity logs were returned. None of the patients reported adverse effects. CONCLUSION: Objective indicators of exercise are warranted in future studies to examine whether exercise is indeed the mechanism of the FatigueUCope effect and determine the clinical utility of this intervention. This brief, engaging tablet-based multimedia education and prescription program has promise to help patients recognize the benefits of exercise to manage cancer-related fatigue.

Formative Evaluation and Adaptation of a Navajo Cancer Survivor Physical Activity Intervention to Serve a Broader Native American Cancer Survivor Community.

BACKGROUND: Although exercise has been shown to improve cancer survivorship in other communities, cancer exercise studies among Native American communities are rare. We sought to adapt a Navajo-tailored cancer exercise pilot program to serve a broader Native American cancer community. METHODS: Tribal experts representing 10 different Tribal Nations were engaged in small focus groups (n=2-4) to assess program materials for cultural appropriateness and adaptation to expand tribal inclusiveness. Facilitated by a trained Native American interviewer, focus groups were provided a primer survey and then reviewed intervention materials (protocols, incentives, logo, flyers, etc.). Consensus was reached by the research team on all program adaptations. RESULTS: The program name, Restoring Balance, layout, graphics, and symbols were considered culturally appropriate overall. Program exercises and biomarker measurements were viewed as valuable to health improvements in the community. Important color, linguistic, and logistic program modifications were recommended to improve cultural alignment. The order of incentive items was revised to highlight restoration and the logo rotated to align with the four corners of the earth, an important cultural element. Linguistic modifications primarily related to prior traumatic research experiences in Native American communities where data had been taken without adequate community benefit or permission. Program emphasis should be on nurturing, added value and giving. CONCLUSION AND RELEVANCE: The methodology used for cultural expert review was successful in eliciting adaptations to expand the tribal inclusiveness of Restoring Balance. Culture, as well as historically traumatic research experiences, among Native American populations must be considered when adapting health promotion programming.

Moving through cancer: Setting the agenda to make exercise standard in oncology practice.

LAY SUMMARY: International evidence-based guidelines support the prescription of exercise for all individuals living with and beyond cancer. This article describes the agenda of the newly formed Moving Through Cancer initiative, which has a primary objective of making exercise standard practice in oncology by 2029.

Perceptions of Cancer Causes, Prevention, and Treatment Among Navajo Cancer Survivors.

Native Americans experience cancer-related health disparities. Yet, little is known about the current cancer experience in one of the largest Native American tribe, Navajo. A qualitative study of among Navajo cancer survivors, in which focus groups and individual interviews included questions related to perceptions of cancer causes, prevention, and treatment, allowed us to evaluate several aspects of the cancer experience from the Navajo perspective. An experienced, bilingual facilitator led the discussions using a standardized guide. Discussions were audio-recorded, documented by field notes, translated, as needed, and transcribed. NVivo software was used to summarize major themes according to the PEN-3 and health belief models. Navajo cancer survivors (N = 32) were both males (n = 13) and females (n = 19) that had been previously diagnosed with a variety of cancers: colorectal, breast, ovarian, cervical, esophageal, gall bladder, stomach, prostate, kidney, and hematologic. Many survivors had accurate knowledge of risk factors for cancer. Barriers to screening and clinical care included language, expense, geography, fear, lack of information, skepticism related to Western medicine, and treatment side effects. While some survivors experienced familial support, others were isolated from the family and community due to the perspective of cancer as a contagion. However, resilience, hope, trust in select community organizations, a desire to restore balance, and to support younger generations were positive attributes expressed regarding the treatment and recovery process. These evaluations need to be replicated across a larger cross-section of the Native cancer survivor community.

Nutrition and physical activity guidelines for cancer survivors.

Cancer survivors are often highly motivated to seek information about food choices, physical activity, and dietary supplements to improve their treatment outcomes, quality of life, and overall survival. To address these concerns, the American Cancer Society (ACS) convened a group of experts in nutrition, physical activity, and cancer survivorship to evaluate the scientific evidence and best clinical practices related to optimal nutrition and physical activity after the diagnosis of cancer. This report summarizes their findings and is intended to present health care providers with the best possible information with which to help cancer survivors and their families make informed choices related to nutrition and physical activity. The report discusses nutrition and physical activity guidelines during the continuum of cancer care, briefly highlighting important issues during cancer treatment and for patients with advanced cancer, but focusing largely on the needs of the population of individuals who are disease free or who have stable disease following their recovery from treatment. It also discusses select nutrition and physical activity issues such as body weight, food choices, food safety, and dietary supplements; issues related to selected cancer sites; and common questions about diet, physical activity, and cancer survivorship.

Initiating Exercise Interventions to Promote Wellness in Cancer Patients and Survivors.

Exercise is associated with significant reductions in the recurrence and mortality rates of several common cancers. Cancer survivors who exercise can potentially benefit from reduced levels of fatigue, and improved quality of life, physical function, and body composition (ie, healthier ratios of lean body mass to fat mass). The amount of activity required to achieve protective effects is moderate (eg, walking 30 minutes per day at 2.5 miles per hour). However, many healthcare providers report a lack of awareness of the appropriate exercise recommendations across the phases of cancer survivorship, considerations regarding the timing of exercise interventions, and the ability to refer patients to exercise programs specifically aimed at cancer survivors. The American College of Sports Medicine notes that exercise is generally safe for most cancer survivors, and inactivity should be avoided. Their guidelines for exercise call for 150 minutes of moderate or 75 minutes of vigorous aerobic activity per week, and 2 days per week of resistance training (eg, with exercise bands or light weights). Survivors with lymphedema, peripheral neuropathy, breast reconstruction, central lines, and ostomies should follow specific precautions. Providing health professionals with the training and tools needed to provide adequate recommendations to their patients is essential to improving patient outcomes. To facilitate adherence among communities with the greatest need and poor access to services, cultural and environmental adaptations are critical.

Effect of weight loss on bone health in overweight/obese postmenopausal breast cancer survivors.

Current guidelines recommend weight loss in obese cancer survivors. Weight loss, however, has adverse effects on bone health in obese individuals without cancer but this has not been evaluated in breast cancer survivors. We investigated the associations of intentional weight loss with bone mineral density (BMD) and bone turn-over markers in overweight/obese postmenopausal breast cancer survivors. Participants were overweight/obese breast cancer survivors (N = 81) with stage I, II or IIIA disease enrolled in the St. Louis site of a multi-site Exercise and Nutrition to Enhance Recovery and Good health for You (ENERGY) study; a randomized-controlled clinical trial designed to achieve a sustained ≥7 % loss in body weight at 2 years. Weight loss was achieved through dietary modification with the addition of physical activity. Generalized estimating equations were used to assess differences in mean values between follow-up and baseline. Mean weight decreased by 3 and 2.3 % between baseline and 6-month follow-up, and 12-month follow-up, respectively. There were decreases in osteocalcin (10.6 %, p value < 0.001), PINP (14.5 %, p value < 0.001), NTx (19.2 % p value < 0.001), and RANK (48.5 %, p value < 0.001), but not BALP and CTX-1 levels between baseline and 12-month follow-up. No significant changes occurred in mean T-scores, pelvis and lumbar spine BMD between baseline and 12-month follow-up. A 2.3 % weight loss over 12 months among overweight/obese women with early-stage breast cancer does not appear to have deleterious effect on bone health, and might even have beneficial effect. These findings warrant confirmation, particularly among breast cancer survivors with a larger magnitude of weight loss.

Looking back: a review of policy implications for exercise oncology.

The evidence to support the benefits of exercise for people living with and beyond cancer is robust. Still, exercise oncology interventions in the United States are only eligible for coverage by third-party payers within the restrictions of cancer rehabilitation settings. Without expanded coverage, access will remain highly inequitable, tending toward the most well-resourced. This article describes the pathway to third-party coverage for 3 programs that address a chronic disease and utilize exercise professionals: the Diabetes Prevention Program, Supervised Exercise Training for Peripheral Artery Disease, and Cancer Rehabilitation. Lessons learned will be applied toward expanding third-party coverage for exercise oncology programming.

Prospective surveillance and management of cardiac toxicity and health in breast cancer survivors.

Breast cancer is commonly diagnosed in postmenopausal women, the majority of whom express 1 or more cardiovascular disease risk factors. Cardiovascular disease poses a significant competing risk for morbidity and mortality among nonmetastatic breast cancer survivors. Adjuvant systemic therapies may result in late-cardiac toxicity decades after treatment completion. The cumulative incidence of treatment-related cardiotoxic outcomes may be as high as 33% after some adjuvant breast cancer therapies. Breast cancer treatment-induced cardiotoxicity may manifest as cardiomyopathy, coronary ischemia, thromboembolism, arrhythmias and conduction abnormalities, and valvular and pericardial disease. Evidence indicates that preexisting cardiovascular conditions such as hypertension or left ventricular dysfunction may compound the adverse effects of cardiotoxic treatments. There are currently no published clinical practice guidelines that address ongoing cardiac surveillance for cardiotoxicity after breast cancer, and existing guidelines for monitoring and promoting cardiovascular health in older women are often not followed. The multidisciplinary prospective surveillance system proposed elsewhere in this supplement would allow for earlier detection of cardiotoxicity from treatment and may improve monitoring of cardiovascular health in the growing population of breast cancer survivors.

A prospective model of care for breast cancer rehabilitation: bone health and arthralgias.

Musculoskeletal health can be compromised by breast cancer treatment. In particular, bone loss and arthralgias are prevalent side effects experienced by women treated with chemotherapy and/or adjuvant endocrine therapy. Bone loss leads to osteoporosis and related fractures, while arthralgias threaten quality of life and compliance to treatment. Because the processes that lead to these musculoskeletal problems are initiated when treatment begins, early identification of women who may be at higher risk of developing problems, routine monitoring of bone density and pain at certain stages of treatment, and prudent application of therapeutic interventions are key to preventing and/or minimizing musculoskeletal sequelae. Exercise may be a particularly suitable intervention strategy because of its potential to address a number of impairments; it may slow bone loss, appears to reduce joint pain in noncancer conditions, and improves other breast cancer outcomes. Research efforts continue in the areas of etiology, measurement, and treatment of bone loss and arthralgias. The purpose of this review is to provide an overview of the current knowledge on the management and treatment of bone loss and arthralgias in breast cancer survivors and to present a framework for rehabilitation care to preserve musculoskeletal health in women treated for breast cancer.

Implementing the exercise guidelines for cancer survivors.

In 2009, the American College of Sports Medicine convened an expert roundtable to issue guidelines on exercise for cancer survivors. This multidisciplinary group evaluated the strength of the evidence for the safety and benefits of exercise as a therapeutic intervention for survivors. The panel concluded that exercise is safe and offers myriad benefits for survivors including improvements in physical function, strength, fatigue, quality of life, and possibly recurrence and survival. Recommendations for situations in which deviations from the US Physical Activity Guidelines for Americans are appropriate were provided. Here, we outline a process for implementing the guidelines in clinical practice and provide recommendations for how the oncology care provider can interface with the exercise and physical therapy community.

Returning to Sport: Female Athletes Living with and beyond Cancer.

Many athletes living with and beyond cancer can continue to train and, in some cases, compete during treatment. Following cancer treatment, athletes can return to competitive sport but need to learn to adapt their physical strength and training to the lingering effects of cancer. It is critical for oncology healthcare providers to use the principles of assess, refer and advise to exercise oncology programs that are appropriate for the individual. Managing side effects of treatment is key to being able to train during and immediately following cancer treatment. Keen attention to fatigue is important at any point in the cancer spectrum to avoid overtraining and optimize the effects of training. Resources are introduced for providers to reference and direct patients to information for psychosocial support and instruction. The purpose of this paper is to present exercise considerations during and after cancer treatment for athletic cancer survivors.

Mentoring New and Early-Stage Investigators and Underrepresented Minority Faculty for Research Success in Health-Related Fields: An Integrative Literature Review (2010-2020).

Mentoring to develop research skills is an important strategy for facilitating faculty success. The purpose of this study was to conduct an integrative literature review to examine the barriers and facilitators to mentoring in health-related research, particularly for three categories: new investigators (NI), early-stage investigators (ESI) and underrepresented minority faculty (UMF). PsychINFO, CINAHL and PubMed were searched for papers published in English from 2010 to 2020, and 46 papers were reviewed. Most papers recommended having multiple mentors and many recommended assessing baseline research skills. Barriers and facilitators were both individual and institutional. Individual barriers mentioned most frequently were a lack of time and finding work-life balance. UMF mentioned barriers related to bias, discrimination and isolation. Institutional barriers included lack of mentors, lack of access to resources, and heavy teaching and service loads. UMF experienced institutional barriers such as devaluation of experience or expertise. Individual facilitators were subdivided and included writing and synthesis as technical skills, networking and collaborating as interpersonal skills, and accountability, leadership, time management, and resilience/grit as personal skills. Institutional facilitators included access to mentoring, professional development opportunities, and workload assigned to research. Advocacy for diversity and cultural humility were included as unique interpersonal and institutional facilitators for UMF. Several overlapping and unique barriers and facilitators to mentoring for research success for NI, ESI and UMF in the health-related disciplines are presented.

Precision mentoring (PM): a proposed framework for increasing research capacity in health-related disciplines.

PROBLEM: Research productivity is expected of academic faculty, and mentoring can facilitate it. This paper presents a framework for using mentoring to develop researchers in health disciplines. APPROACH: We utilized recent literature reviews, and experience developing researchers at an emerging research institution within the Research Centers for Minority Institutions (RCMI) program, to propose a precision mentoring (PM) framework for research development. OUTCOMES: Although we cannot precisely determine how much improvement was due to the PM framework, over the 4 years of our program, the quality and quantity of pilot project proposals (PPP) has increased, the number of external proposals submitted and funded by PPP investigators has increased, and the number of faculty participating in our program has increased. Surveys distributed to our 2021-22 PPP applicants who did not receive funding (n = 5/6 or 86.7%) revealed that new investigators most frequently sought mentoring related to career guidance (e.g., institutional culture, pre-tenure survival strategies), grant proposal basics (e.g., working with funding agencies, reviewing aims, balancing priorities, and enhancing scientific rigor), and identifying funding opportunities. NEXT STEPS: We recommend shifting the mentoring paradigm such that: (a) mentees are pre-screened and re-screened for their current skill set and desired areas of growth; (b) mentoring occurs in teams vs. by individuals; (c) mentors are trained and rewarded, and (d) attention is paid to enhancing institutional culture.

The impact of resistance training on body composition, muscle strength, and functional fitness in older women (45-80 years): A systematic review (2010-2020).

As women age, they typically experience a progressive decrease in skeletal muscle mass and strength, which can lead to a decline in functional fitness and quality of life. Resistance training (RT) has the potential to attenuate these losses. Although well established for men, evidence regarding the benefits of RT for women is sparse and inconsistent: prior reviews include too few studies with women and do not adequately examine the interactive or additive impacts of workload, modalities, and nutritional supplements on outcomes such as muscle mass (MM), body composition (BC), muscle strength (MS), and functional fitness (FF). The purpose of this review is to identify these gaps. Thirty-eight papers published between 2010 and 2020 (in English) represent 2519 subjects (mean age = 66.89 ± 4.91 years). Intervention averages include 2 to 3 × 50 min sessions across 15 weeks with 7 exercises per session and 11 repetitions per set. Twelve studies (32%) examined the impact of RT plus dietary manipulation. MM, MS, and FF showed positive changes after RT. Adding RT to fitness regimens for peri- to postmenopausal women is likely to have positive benefits.

Effects of a 12-month randomized controlled trial of aerobic or resistance exercise during and following cancer treatment in women.

Weight gain is common during and following cancer treatment and contributes to many adverse health consequences and increased risk of recurrence for cancer survivors. The purpose of this longitudinal randomized controlled trial was to compare differences in weight change and body composition among newly diagnosed cancer survivors receiving chemotherapy who were randomly assigned to usual care control, aerobic exercise, or resistance exercise interventions. It was hypothesized that cancer survivors become more sedentary during treatment, leading to positive energy balance that in turn worsens body composition. One hundred one subjects completed the 12-month study. Data collected included body composition (body weight and dual energy x-ray absorptiometry scan), aerobic capacity (12-minute walk), and muscle strength (1 repetition maximum). Aerobic exercisers were found to have significant improvements in body composition, aerobic capacity, and muscle strength. Resistance exercisers also benefitted, but were less compliant with the intervention over time. Thus, exercise during and following cancer treatment is an important intervention to maintain and perhaps improve body composition of cancer survivors, which may improve survival, reduce comorbidities, and improve quality of life.

Development of a culturally relevant physical activity intervention for Navajo cancer survivors.

Despite well-documented benefits of physical activity for cancer survivors, few interventions have been developed for Native American cancer survivors, the population with the poorest survival rates of any group. This paper describes the development and cultural adaptation of a physical activity intervention for Navajo cancer survivors using Intervention Mapping (IM). IM procedures were guided by the PEN-3 (Perceptions-Enablers-Nurturers) and Health Belief Models and informed by a qualitative study with 40 Navajo cancer survivors and family members. For each theoretical construct (perceived benefits, barriers, enablers of healthy behaviors, etc.), a measurable objective was identified. These objectives were then matched with intervention strategies. The IM process indicated the need for a highly culturally sensitive environment (site and providers), culturally acceptable measurements and materials, and integrating cultural and environmental activity preferences. Program objectives aligned directly with these areas. Intervention strategies included: (a) collaboration with providers sensitive to historical/cultural context and environmental barriers; (b) cultural adaptation of surveys, non-invasive physical measurements, no biospecimen storage; (c) materials, terminology and symbols embracing cultural values of return to harmony; (d) physical activities that are flexible and aligned with cultural preferences and environment/travel issues (e.g., outdoor walking; community and home-based options; portable, inexpensive resistance equipment; local resources; family/friends participation and more community cancer education); (e) clinical adaptations by site and symptoms. This study is the first to document the process of adaptation of a physical activity program for Navajo cancer survivors. Objectives and strategies incorporated via IM are expected to foster sustainability and enhance uptake, satisfaction, and adherence.
