Physical activity and cancer survivorship

Family-Focused Facilitated Fitness: Feasibility and Acceptability of a Couple-Based Physical Activity Intervention for Hematopoietic Cell Transplant Recipients and Their Caregiving Partners

Reductions in physical activity (PA) are common among patients following hematopoietic cell transplantation, and a risk factor for poor physical functioning. PA among spouses/cohabiting partners, who frequently serve as the patient's primary caregiver, may also be reduced due to caregiving demands and limited bandwidth for self-care. In addition, the patient-caregiver relationship can be compromised, and communication patterns disrupted. All PA interventions in the hematopoietic cell transplantation setting have focused entirely on patients, ignoring an opportunity to synergistically engage and benefit the caregiver as well. We sought to test feasibility and acceptability of a couple-based intervention entitled Family-Focused Facilitated Fitness (FFFF), designed to improve PA as assessed by daily step counts among both patients undergoing hematopoietic cell transplantation and their caregivers. Guided by interdependence and communal coping perspectives, FFFF is an 8-week, remotely-delivered intervention that provides training in communication skills and joint problem-solving to help patients and caregivers support one another in PA. Participants are also given a Fitbit to track their steps and weekly individualized step prescription based on the 75th percentile ranked value of their last 7 recorded daily step counts. A priori benchmarks for feasibility and acceptability in this single-arm pilot were as follows: 50% of eligible couples would agree to participate, 70% of couples would attend all 8 sessions, 80% of participants would provide valid Fitbit wear data 4/7 days/ week, and among sessions reviewed for treatment fidelity, 85% of treatment protocol elements would be covered. Couples were recruited prior to transplant. Among 26 couples approached and deemed eligible, 17 enrolled (65% agreement) and completed baseline assessment. Three couples later withdrew after transplantation but prior to receiving the intervention, resulting in 14 couples commencing the intervention, on average 21 days post-transplant. Four couples subsequently discontinued due to medical complications (n = 3) or caregiver schedule (n = 1). Among the 10 couples who completed the intervention, the percentage of participants meeting our benchmark of valid Fitbit wear at least 4 days per week was 85% in week 1, 90% in weeks 2 to 7, and 80% in week 8. Treatment fidelity was 95% on average across 24 sessions reviewed (3 cases). Treatment satisfaction scores were uniformly high across multiple dimensions, with all means above 4 on the 1 to 5 scale. Daily step counts among those attending all 8 intervention sessions increased from 2249 ± 302 steps/day in week 1 to 4975 ± 1377 steps/day in week 8 among patients, and from 8676 ± 3760 steps/day in week 1 to 9838 ± 3723 steps/day in week 8 among caregivers. Qualitative feedback indicated perceived mental and physical health benefits of the program. Participants also offered suggestions for adaptations to accommodate medical setbacks and constraints. All a priori feasibility benchmarks were met or exceeded. Results offer promise for utility of the program to engage and leverage patient-caregiver dyads to increase PA following transplant. An investigation using a randomized controlled design will be necessary to adequately examine change over time relative to control and its possible impact on clinical and patient-reported outcomes.

Home-based exercise interventions' impact on breast cancer survivors' functional performance: a systematic review

INTRODUCTION

Home-based exercise (HBE) programs can be a feasible strategy to enhance functional performance and promote physical activity (PA) in breast cancer survivors. A deeper analysis of the effects of HBE interventions, structured by HBE program type and treatment phase, is needed. This systematic review aimed to synthesize the evidence on HBE interventions' impact on breast cancer survivors' functional performance, PA levels, and program adherence rates, according to HBE intervention type and treatment phase.

METHODS

A comprehensive search of peer-reviewed articles reporting HBE interventions' effects on the outcomes of interest was performed in Pubmed, Google Scholar, EBSCO, Web of Science, Science Direct, and B-ON until January 15th, 2024. Data were synthesized according to Denton's domains to classify HBE interventions (prescription: structured vs. unstructured; Delivery method: supervised vs. facilitated vs. unsupervised) and treatment phase. Methodological quality appraisal was performed using the Effective Public Health Practice Project tool.

RESULTS

Twenty-six studies were included. Most studies conducted structured/facilitated interventions and reported positive effects on functional performance (particularly aerobic capacity), increases in PA levels, and high adherence rates (> 70%) during and post-treatment.

CONCLUSION

HBE interventions may be feasible to improve functional performance and promote physical activity among breast cancer survivors. Further studies are needed to confirm which HBE intervention type is more appropriate for each treatment phase. More evidence applying HBE interventions with different designs is required to allow the drawing of more solid conclusions. Studies exploring the effects of HBE interventions on the pre-treatment phase are needed.

The frequency of using wearable activity trackers is associated with minutes of moderate to vigorous physical activity among cancer survivors: Analysis of HINTS data

BACKGROUND

Despite the health benefits, cancer survivors tend to exercise less after diagnosis and treatment. Wearable activity trackers (WATs) can provide avenues for self-monitoring and may enhance exercise motivation and enjoyment. However, less is known about the relationship between how often survivors use wearables and their amount of moderate to vigorous physical activity (MVPA).

METHODS

Data was utilized from the National Cancer Institute's Health Information National Trend Survey 5 Cycles 3-4 (January 2019 - June 2020). To account for overdispersion and excessive zeros in the outcome variable (weekly minutes of MVPA), a zero inflated negative binomial regression model was used.

RESULTS

The majority of the sample (n = 1369) were female (n = 735, 53.7 %), non-Hispanic White (n = 961, 70.2 %) and 34.3 % (n = 664) were between the ages of 65-74 years. Non-melanoma skin cancer was the most frequently reported cancer type (n = 334, 24.4 %) and 48.5 % (n = 664) reported that it had been 11 + years since their diagnosis. Survivors who reported daily WAT use were estimated to have 3.53 times higher number of MVPA minutes per week compared to survivors who reported non-daily WAT usage (RR: 3.53, 2.76-4.53, p = <0.001). Based on the model, daily WAT users had an expected mean MVPA of 202 min per week (95 % CI: 191.15-226.59) compared to non-daily users (132 min, 95 % CI: 119.81-140.22) and non-WAT users (88 min, 95 % CI: 84.46-92.50).

CONCLUSION

According to this model, survivors who reported daily WAT use were estimated on average to have weekly MVPA minutes that meet or exceed MVPA recommendations (>= 150 min of MVPA per week) compared to survivors who reported infrequent or no WAT use. Wearables may provide an opportunity for survivors to engage in self-monitoring and can potentially support exercise tracking and engagement.

The feasibility of an exercise intervention after robotic-assisted radical cystectomy for urinary bladder cancer, prior to the CanMoRe trial

BACKGROUND

Complications after radical cystectomy for urinary bladder cancer are common. Physical activity after surgery is thought to reduce complications. However, patients with urinary bladder cancer have low levels of physical activity, and interventions supporting physical exercise are needed. This study aimed to evaluate the feasibility of a physical exercise intervention in primary health care. One of the aims of the larger clinical trial will be to reduce complications.

METHODS

Patients with urinary bladder cancer and who were scheduled for a robotic-assisted radical cystectomy were recruited from Karolinska University Hospital, between February and May 2019. The patients had to be mobile, understand Swedish, and live in Stockholm. The exercise programme was conducted at one primary health care setting over 12 weeks. The exercise programme included supervised aerobic and strengthening exercises, which were performed twice a week, as well as daily walks. Feasibility was measured with process feasibility, including eligibility criteria, adherence, and acceptability, and scientific feasibility, including the ability of outcomes to indicate change, safety, and progression in the exercise programme.

RESULTS

Ten patients with a median age of 70 years (min 53-max 86) were included. Adherence to all parts of the intervention was not feasible because of patients' postoperative complications, resulting in dropouts. For the patients who took part in the exercise programme, adherence and acceptability for the exercise period were feasible, but the 6-min walk test was not feasible at discharge from the hospital. Physiotherapists in the primary health care setting perceived the process as feasible. Moreover, the ability of outcomes to indicate change and progression in the exercise programme was feasible, meanwhile no adverse events were registered.

CONCLUSIONS

The exercise intervention was feasible for the patients that took part in the exercise programme, with respect to safety and progression through the exercise programme. Furthermore, this study suggests that some improvements needed to be implemented in the process, prior to the upcoming randomised controlled trial.

Cancer Metabolism as a Therapeutic Target and Review of Interventions

Cancer is amenable to low-cost treatments, given that it has a significant metabolic component, which can be affected through diet and lifestyle change at minimal cost. The Warburg hypothesis states that cancer cells have an altered cell metabolism towards anaerobic glycolysis. Given this metabolic reprogramming in cancer cells, it is possible to target cancers metabolically by depriving them of glucose. In addition to dietary and lifestyle modifications which work on tumors metabolically, there are a panoply of nutritional supplements and repurposed drugs associated with cancer prevention and better treatment outcomes. These interventions and their evidentiary basis are covered in the latter half of this review to guide future cancer treatment.

Race, ethnicity, and experienced racism are associated with adverse physical and mental health outcomes among cancer survivors

INTRODUCTION

Survivors of cancer are at risk for adverse mental and physical health outcomes. It is not well understood, however, how these outcomes are differentially experienced according to an individual's exposure to racism. This study sought to evaluate associations of race/ethnicity, and experiences of racism, with adverse health outcomes in survivors of cancer.

METHODS

Using the Behavioral Risk Factor Surveillance System database, data from 48,200 survivors between 2014 and 2020 were evaluated. Survey items included negative physical and emotional symptoms as a result of race-based treatment. Outcomes of interest included days of poor mental and physical health, activity limitations, depression, and inadequate sleep. Associations using prevalence ratios were evaluated.

RESULTS

All historically marginalized racial/ethnic groups were more likely to experience at least one adverse health outcome compared with non-Hispanic White survivors. Those who physically experienced racism were 2.1 (95% CI, 1.64-2.69) times as likely to report poor physical health, 3.51 (95% CI, 2.61-4.71) times as likely to report poor mental health, 2.14 (95% CI, 1.77-2.58) times as likely to report inadequate sleep, 2.33 (95% CI: 1.91-2.83) times as likely to report depression, and 1.42 (95% CI, 1.04-1.93) times as likely to report activity limitations compared with those who have not experienced racism. Similar associations were observed for emotionally experienced racism.

DISCUSSION

Racial inequities in health outcomes for survivors of cancer from marginalized racial/ethnic groups are well-established. Experienced racism contributes to adverse health outcomes and widens these disparities. Improving outcomes for survivors of cancer may require screening for experienced racism.

PLAIN LANGUAGE SUMMARY

Survivors of cancer from marginalized racial/ethnic populations are more likely to have poor mental and physical health than their non-Hispanic White counterparts. Whether survivors from certain racial/ethnic populations of smaller size also have poorer health is less well understood. Generally, individuals who report experienced racism also report poor health, this association has not been studied in survivors of cancer. This study, from a national survey of survivors of cancer, describes disparities in health outcomes experienced by a variety of racial and ethnic populations. Our findings suggest racism is associated with poor mental and physical health in survivors of cancer.

The impact of high intensity interval training in a diverse group of cancer survivors: CAPABLE, a pilot study

Purpose

Given the well-documented benefits of regular exercise to cancer survivors, current American Cancer Society guidelines recommend that patients engage in a minimum of 150 min per week of moderate-to-vigorous physical activity with a minimum of two days of strength training. However, few survivors meet this goal, particularly among minorities.

Methods

The CAPABLE study is a single-arm, pilot exercise intervention that introduced 48 cancer survivors to a high intensity interval and strength training program three days a week for 12 weeks. We evaluated the impact of this unique training method on bodyweight, % body fat, serum markers correlated with an adverse cardiometabolic profile and health-related quality of life (HRQoL). Measures were summarized at baseline and program exit. Paired t-tests were used to assess change in each of these measures over time.

Results

We observed losses in weight, body mass index, and % body fat, and glycosylated hemoglobin (HbA1c) levels over 12-weeks. There were also clinically meaningful improvements in reported overall HRQoL (FACTG total change +9.5 (95% CI, 4.6, 14.4)) and in each one of the individual domains (physical, social, emotional, and functional well-being).

Conclusions

We observed meaningful improvements in body composition, HbA1c and quality of life over 12 weeks among cancer survivors participating in a high-intensity interval training program. Future work will include a control arm for comparison and address barriers to participation and adherence which will be important in using this intervention and others like it to improve outcomes and reduce cancer health disparities.

Development and pilot testing of a clinic implementation program delivering physical activity electronic referrals to cancer survivors

Provider physical activity referrals are recommended for cancer survivors, though barriers exist to clinical system integration. To develop and test ActivityChoice, an electronic referral (eReferral) clinic implementation program referring cancer survivors to physical activity programs of their choice. In Phase 1, we conducted semi-structured interviews with Cancer Center clinicians (n = 4) and cancer-focused physical activity program leaders (n = 3) assessing adaptations needed to implement an eReferral previously designed for another context. In Phase 2, we pilot-tested clinician-delivered referrals to survivors in two 12-week Plan, Do, Study, Act (PDSA) cycles. We examined feasibility using descriptive statistics (clinicians' adoption and engagement, patient referrals, and physical activity program enrollment) and acceptability through semi-structured interviews with enrolled clinicians (n = 4) and referred patients (n = 9). ActivityChoice included a secure referral webform, text message/email referral confirmations, clinician training/booster sessions, visual reminders, and referrals to in-person or virtual group physical activity programs. Results for each PDSA cycle respectively included: 41% (n = 7) and 53% (n = 8) of clinicians adopted ActivityChoice; 18 and 36 patients were referred; 39% (n = 7) and 33% (n = 12) of patients enrolled in programs, and 30% (n = 4) and 14% (n = 5) of patients deferred enrollment. Patients and clinicians appreciated the referrals and choices. A printed handout describing both programs was added to the clinic workflow for Cycle 2, which yielded more referrals, but lower program enrollment rates. Clinic-based eReferrals to choices of physical activity programs were feasible and acceptable by clinicians and patients. Added clinic workflow support may facilitate referrals.

Association between physical activity and body posture: a systematic review and meta-analysis

OBJECTIVE

To estimate the possible associations between posture and physical activity (PA).

DESIGN

A systematic review and meta-analysis.

DATA SOURCES

The search was conducted in seven databases (PubMed, Web of Science, SportDiscus, EMBASE, Scopus, Cochrane Library, and CINAHL) for studies published from inception to January 2023.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies were required to meet following criteria: (1) study design: cross-sectional, case control and cohort studies. (2) Participants: people of all ages without any diagnosed diseases. (3) Exposure and outcome: studies that examined the possible effect or correlations between PA, physical inactivity, physical exertion and human body posture.

RESULTS

Sixteen cross-sectional studies, two cohort studies and one case control study involving a total of 16772 participants aged from 6 to 79 years were included. Correlational studies showed that there was a significant relationship between PA and posture (C = 0.100, CI 95% = 0.012-0.186). However, regression studies demonstrated that there was not a significant association between PA and posture (C = 1.00, CI 95% = 0.998-1.002). Three studies investigated the association between PA and the lumbar lordosis and showed that there was not a significant association between the lordosis and PA (CI 95%: -0.253-0.048, P = 0.180). In addition, four studies showed that there were not any associations between scoliosis and PA (CI 95%: 0.819, 1.123, P = 0.607). The evidence of heterogeneity and publication bias was found among all analyzed data (P < 0.05). Also, meta regression was used for age and BMI and the results were not significant.

CONCLUSION

Although a weak correlation was shown to exist between PA and human posture, the odds ratio indicated that there was not a significant association between PA and human posture. The lack of a significant relationship may indicate that multiple biopsychosocial factors may be involved in human posture. In summary, our study highlights the need for caution when interpreting the results of meta-analyses, particularly when there is significant heterogeneity and publication bias in the included studies.

Comparison of Quality of Life in Breast Cancer Survivors with and without Persistent Depressive Symptoms: A 12-Month Follow-Up Study

Although breast cancer treatments reduce mortality, their adverse effects can increase depression which impacts one's quality of life (QoL). Physical activity (PA) seems to improve the QoL of breast cancer survivors (BCS). However, an unanswered question is the influence of PA on the QoL in BCS with depressive symptoms. Thus, we analyzed the influence of PA on the QoL in BCS with persistent depressive symptoms during 12 months of follow-up. The sample included 70 female BCS. Depression and QoL domains (i.e., functional capacity, physical limitations, body pain, general health status, vitality, social and emotional aspects, and mental health) were assessed at baseline and follow-up periods by the Hospital Anxiety and Depression Scale and SF-36, respectively. Habitual PA was assessed by Baecke's questionnaire. Our results indicate a prevalence of 17.1% of depressive symptoms. Non-depressives BCS improved their physical limitations and general health status domains over time, but there were no observed differences in depressive BCS. BCS with persistent depressive symptoms (baseline and follow-up) showed worse QoL scores than non-depressives in all domains, regardless of confounding factors. When adjusted for PA, the difference between BCS depressives and non-depressives lost its significance in the functional capacity domain. In conclusion, habitual PA practice positively influenced the functional capacity domain of the QoL in BCS.

Football training as a non-pharmacological treatment of the global aging population-A topical review

In the present topical mini-review, the beneficial impact of small-sided game football training for the increasing elderly global population is presented. As a multicomponent type of physical activity, football training executed on small pitched with 4-6 players in each team is targeting a myriad of physiological systems and causes positive adaptations of relevance for several non-communicable diseases, of which the incidence increases with advancing age. There is strong scientific evidence that this type of football training promotes cardiovascular, metabolic and musculo-skeletal health in elderly individuals. These positive adaptations can prevent cardiovascular disease, type 2 diabetes, sarcopenia and osteoporosis, and lower the risk of falls. Also, football training has been proven an efficient part of the treatment of several patient groups including men with prostate cancer and women after breast cancer. Finally, regular football training has an anti-inflammatory effect and may slow the biological aging. Overall, there is a growing body of evidence suggesting that recreational football training can promote health in the elderly.

Associations of Physical Activity and Handgrip Strength with Health-Related Quality of Life in Older Korean Cancer Survivors

Background: Uncertainty exists regarding the associations between physical activity (PA), relative handgrip strength (RHGS), and health-related quality of life (HRQoL) among elderly Korean cancer survivors. This study investigated the moderating effect of RHGS on the relationship between PA and HRQoL in 308 cancer survivors aged ≥65 years using the data from the Korean National Health and Nutrition Examination Survey in 2014−2019. Methods: HRQoL was evaluated with the EuroQol-5-dimension instrument. PA and handgrip strength were assessed with the Global Physical Activity Questionnaire and a hand dynamometer, respectively. Age, sex, body mass index, income, marital status, educational background, heavy alcohol consumption, smoking status, multimorbidity, and hemoglobin were included as covariates. Results: Bivariate logistic regression showed that insufficient PA and no PA were associated with higher odds of a low HRQoL (odds ratio, OR = 2.6, 95% confidence interval, CI = 1.3~5.1, p = 0.005; OR = 2.4, 95% CI = 1.1~5.0, p = 0.024, respectively), compared with sufficient PA (OR = 1). Weak RHGS was associated with high odds of a low HRQoL (OR = 2.6, 95%= 1.530~4.6, p < 0.001) compared with normal RHGS (OR = 1). Particularly, RHGS (β = −0.0573, 95% CI = −0.1033~−0.0112) had a significant moderating effect on the relationship between PA and HRQoL even after adjustments for all the covariates. The negative influence of physical inactivity on HRQoL was observed in cancer survivors with weak RHGS but not in cancer survivors with normal RHGS. Conclusions: The current findings suggest that maintaining or promoting muscular strength through regular exercise is critical for the HRQoL of elderly Korean cancer survivors.

Interventions to Reduce Sedentary Behavior in Cancer Patients and Survivors: a Systematic Review

PURPOSE OF REVIEW

Sedentary behaviors (SB) after cancer diagnosis are associated with poor prognosis for certain cancers, and cancer patients and survivors report high levels of SB. Reducing SB may be a feasible and effective intervention strategy to improve outcomes. This systematic review aims to identify and evaluate the literature on interventions to reduce SB in cancer patients and survivors.

RECENT FINDINGS

Studies were identified via database searches in December 2020. Two authors evaluated study eligibility. Data were extracted and checked, and risk of bias was assessed by the study team. Of 1401 records identified, nine studies involving 394 cancer patients or survivors were included in this review. Six were randomized trials, three were non-randomized intervention studies, and almost all (n = 8) focused on feasibility with small sample sizes. All studies were conducted within the previous 5 years in Canada, Australia, USA, and South Korea. Cancer types studied were breast (n = 3), prostate (n = 2), colorectal or peritoneal (n = 1), and mixed types (n = 3). Intervention duration of 12 weeks was most common (n = 7). Five studies had multiple intervention components, and six studies included wearable devices to measure and/or prompt behavior change. There was an overall trend where intervention groups reduced SB vs. control groups, often coupled with an increase in moderate-to-vigorous physical activity. This review suggests that there is some promise for intervention strategies to reduce SB in cancer patients and survivors. There is a need for more high-quality randomized controlled trials to understand how to best decrease SB in cancer patients and survivors.

Factors associated with changes in exercise behaviors during the COVID-19 pandemic

PURPOSE

There is limited information on how the COVID-19 pandemic has changed health behaviors among cancer patients. We examined changes in exercise behaviors since the pandemic and identified characteristics associated with these changes among cancer patients.

METHODS

Cancer patients (n = 1,210) completed a survey from August to September 2020 to assess COVID-19 pandemic-related changes in health behaviors and psychosocial factors. Patients were categorized into three groups: exercising less, exercising did not change, and exercising more. Patient characteristics were compared by exercise groups.

RESULTS

One-third of the patients reported a decreased amount of regular exercise, while 10% reported exercising more during the pandemic. Patients who exercised less were more likely to be unemployed/retired and have poor health status and psychosocial stressors such as disruptions in daily life while less likely to be former smokers (all p < 0.05). In contrast, patients who exercised more were younger, had stage IV diagnosis, and also reported disruptions in daily life (all p < 0.05). Patients who were living in rural areas were also more likely not to experience changes in exercise habits (all p < 0.05), although rural-urban status was not identified as a strong predictor.

CONCLUSION

A significant proportion of cancer patients experienced changes in exercise habits, especially exercising less, during the first 6 months of the COVID-19 pandemic. Age, employment status, tumor stage, health status, smoking status, and psychosocial factors were associated with changes in exercise behaviors. Our results highlight the importance of promoting physical activity guidelines for cancer survivorship during the COVID-19 pandemic and may help improve the identification of cancer patients susceptible to exercising less.

An app with brief behavioural support to promote physical activity after a cancer diagnosis (APPROACH): study protocol for a pilot randomised controlled trial

Background

There are multiple health benefits from participating in physical activity after a cancer diagnosis, but many people living with and beyond cancer (LWBC) are not meeting physical activity guidelines. App-based interventions offer a promising platform for intervention delivery. This trial aims to pilot a theory-driven, app-based intervention that promotes brisk walking among people living with and beyond cancer. The primary aim is to investigate the feasibility and acceptability of study procedures before conducting a larger randomised controlled trial (RCT).

Methods

This is an individually randomised, two-armed pilot RCT. Patients with localised or metastatic breast, prostate, or colorectal cancer, who are aged 16 years or over, will be recruited from a single hospital site in South Yorkshire in the UK. The intervention includes an app designed to encourage brisk walking (Active 10) supplemented with habit-based behavioural support in the form of two brief telephone/video calls, an information leaflet, and walking planners. The primary outcomes will be feasibility and acceptability of the study procedures. Demographic and medical characteristics will be collected at baseline, through self-report and hospital records. Secondary outcomes for the pilot (assessed at 0 and 3 months) will be accelerometer measured and self-reported physical activity, body mass index (BMI) and waist circumference, and patient-reported outcomes of quality of life, fatigue, sleep, anxiety, depression, self-efficacy, and habit strength for walking. Qualitative interviews will explore experiences of participating or reasons for declining to participate. Parameters for the intended primary outcome measure (accelerometer measured average daily minutes of brisk walking (≥ 100 steps/min)) will inform a sample size calculation for the future RCT and a preliminary economic evaluation will be conducted.

Discussion

This pilot study will inform the design of a larger RCT to investigate the efficacy and cost-effectiveness of this intervention in people LWBC.

Lifestyle and Pain following Cancer: State-of-the-Art and Future Directions

This review discusses chronic pain, multiple modifiable lifestyle factors, such as stress, insomnia, diet, obesity, smoking, alcohol consumption and physical activity, and the relationship between these lifestyle factors and pain after cancer. Chronic pain is known to be a common consequence of cancer treatments, which considerably impacts cancer survivors' quality of life when it remains untreated. Improvements in lifestyle behaviour are known to reduce mortality, comorbid conditions (i.e., cardiovascular diseases, other cancer, and recurrence) and cancer-related side-effects (i.e., fatigue and psychological issues). An inadequate stress response plays an important role in dysregulating the body's autonomic, endocrine, and immune responses, creating a problematic back loop with pain. Next, given the high vulnerability of cancer survivors to insomnia, addressing and treating those sleep problems should be another target in pain management due to its capacity to increase hyperalgesia. Furthermore, adherence to a healthy diet holds great anti-inflammatory potential for relieving pain after cancer. Additionally, a healthy diet might go hand in hand with weight reduction in the case of obesity. Consuming alcohol and smoking have an acute analgesic effect in the short-term, with evidence lacking in the long-term. However, this acute effect is outweighed by other harms on cancer survivors' general health. Last, informing patients about the benefits of an active lifestyle and reducing a sedentary lifestyle after cancer treatment must be emphasised when considering the proven benefits of physical activity in this population. A multimodal approach addressing all relevant lifestyle factors together seems appropriate for managing comorbid conditions, side-effects, and chronic pain after cancer. Further research is needed to evaluate whether modifiable lifestyle factors have a beneficial influence on chronic pain among cancer survivors.

Exercise oncology: an emerging discipline in the cancer care continuum

Exercise is an essential component of healthy living and well-being. While there is a global acceptance of the benefits of exercise for the general population, there exists hesitancy and confusion among health-care professionals, particularly oncologists, as to whether these benefits translate to cancer patients. Patient referrals to accessible, structured exercise programs in this setting are often overlooked by physicians when formulating a cancer management plan. There is however increasing awareness and acceptance of cancer survivorship as a part of the cancer care continuum, identifying multiple factors that contribute to well-being beyond just cancer outcomes. Efforts to optimize cancer survivorship have stimulated further academic interest in the benefits of healthy living and particularly exercise oncology. There is now compelling evidence that exercise, which includes daily activities such as walking, as well as structured programs, improves multiple-cancer outcomes such as fatigue, quality of life and likely survival, and warrants consideration in the multidisciplinary care of cancer patients. International guidelines have been established that recommend counseling cancer patients with regard to healthy lifestyle changes including exercise. However, there still remains a reluctance from oncology physicians to prescribe exercise for these patients, largely due to uncertainty with regard to their patients' ability to tolerate such an intervention, coupled with insufficient understanding of the potential benefits of these programs. There also exist patient barriers and attitudes that must be overcome. Exercise strategies and bespoke programs that are tailored to the unique abilities and goals of the patients will enhance participation. To move the field forward and integrate exercise oncology into standard practice, it is imperative to raise awareness of the benefits of exercise to cancer patients and their health-care providers. This will facilitate the prescription of exercise as part of the multimodal treatment plan with the ultimate aim of promoting an active lifestyle to optimize patient care and well-being.

The Utilization and Benefits of Telehealth Services by Health Care Professionals Managing Breast Cancer Patients during the COVID-19 Pandemic

Telehealth is the delivery of many health care services and technologies to individuals at different geographical areas and is categorized as asynchronously or synchronously. The coronavirus disease 2019 (COVID-19) pandemic has caused major disruptions in health care delivery to breast cancer (BCa) patients and there is increasing demand for telehealth services. Globally, telehealth has become an essential means of communication between patient and health care provider. The application of telehealth to the treatment of BCa patients is evolving and increasingly research has demonstrated its feasibility and effectiveness in improving clinical, psychological and social outcomes. Two areas of telehealth that have significantly grown in the past decade and particularly since the beginning of the COVID-19 pandemic are telerehabilitation and teleoncology. These two technological systems provide opportunities at every stage of the cancer care continuum for BCa patients. We conducted a literature review that examined the use of telehealth services via its various modes of delivery among BCa patients particularly in areas of screening, diagnosis, treatment modalities, as well as satisfaction among patients and health care professionals. The advantages of telehealth models of service and delivery challenges to patients in remote areas are discussed.

Effect of the Rehabilitation Program, ReStOre, on Serum Biomarkers in a Randomized Control Trial of Esophagogastric Cancer Survivors

Background

The Rehabilitation Strategies Following Esophagogastric cancer (ReStOre) randomized control trial demonstrated a significant improvement in cardiorespiratory fitness of esophagogastric cancer survivors. This follow-up, exploratory study analyzed the biological effect of exercise intervention on levels of 55 serum proteins, encompassing mediators of angiogenesis, inflammation, and vascular injury, from participants on the ReStOre trial.

Methods

Patients >6 months disease free from esophagogastric cancer were randomized to usual care or the 12-week ReStOre program (exercise training, dietary counselling, and multidisciplinary education). Serum was collected at baseline (T0), post-intervention (T1), and at 3-month follow up (T2). Serum biomarkers were quantified by enzyme-linked immunosorbent assay (ELISA).

Results

Thirty-seven patients participated in this study; 17 in the control arm and 20 in the intervention arm. Exercise intervention resulted in significant alterations in the level of expression of serum IP-10 (mean difference (MD): 38.02 (95% CI: 0.69 to 75.35)), IL-27 (MD: 249.48 (95% CI: 22.43 to 476.53)), and the vascular injury biomarkers, ICAM-1 (MD: 1.05 (95% CI: 1.07 to 1.66)), and VCAM-1 (MD: 1.51 (95% CI: 1.04 to 2.14)) at T1. A significant increase in eotaxin-3 (MD: 2.59 (95% CI: 0.23 to 4.96)), IL-15 (MD: 0.27 (95% CI: 0 to 0.54)) and decrease in bFGF (MD: 1.62 (95% CI: -2.99 to 0.26)) expression was observed between control and intervention cohorts at T2 (p<0.05).

Conclusions

Impact of the COVID-19 pandemic on exercise habits among cancer patients

Purpose There is limited information on how the COVID-19 pandemic has changed health behaviors among cancer patients. We examined the impact of the pandemic on changes in exercise behaviors and identified characteristics associated with these changes among cancer patients. Methods Cancer patients (n  =  1,361) completed a survey from August-September 2020 to assess COVID-19 pandemic-related changes in health behaviors and psychosocial factors. Patients were categorized into 3 groups: exercising less, exercising did not change, and exercising more. Patient characteristics were compared by exercise groups. Results One-third of the patients reported a decreased amount of regular exercise, while 11% reported exercising more during the pandemic. Patients who exercised less were more likely to be unemployed/retired, undergoing active treatment, and had increased pandemic-related alcohol consumption and psychosocial stressors such as loneliness and financial stress (all p  < 0.05). In contrast, patients who exercised more were younger, female, full-time employed, did not consume alcohol, and had good health status and more social interactions (all p  < 0.05). Patients who were living in rural areas and did not experience changes in daily life, were also more likely not to experience changes in exercise habits (all p  < 0.05). Conclusion Our results indicate that a significant proportion of cancer patients experienced changes in exercise habits during the first 6 months of the COVID-19 pandemic. Age, sex, employment status, health status, alcohol consumption, and psychosocial factors were associated with changes in exercise behaviors. Providers should monitor for changes in health behaviors, such as exercise, because of their importance in improving cancer survivorship.

Age-varying associations between physical activity and psychological outcomes among rural cancer survivors

We examined the prevalence of psychological outcomes (i.e., symptoms of depression and anxiety) by age and age-varying associations between physical activity and psychological outcomes among rural cancer survivors. Participants (N = 219; ages 22-93) completed sociodemographic, psychological, and physical activity questionnaires. Time-varying effect models estimated the prevalence of psychological outcomes and assessed associations between physical activity and psychological outcomes as a flexible function of age. Depression and anxiety symptoms decreased with age among cancer survivors aged 22-40 years and were relatively stable across age among those > 40 years. Positive associations between vigorous physical activity and psychological outcomes in those aged 22-40 years were identified. In those > 70-80 years, there were negative associations between vigorous physical activity and psychological outcomes. Results suggest there is variation across age in the associations between physical activity and psychological outcomes among rural survivors. Future research should further explore these age-varying relationships to identify important intervention targets.

Assessment of Practice and Outcome of Exercise on Quality of Life of Women with Breast Cancer in Delta State

OBJECTIVES

This study evaluated the effect of exercise on the quality of life of women with breast cancer. It determined the pre and post-intervention functional, symptoms, and global quality of life of women with breast cancer in the control and intervention groups.

METHODS

The quasi-experimental design study adopted a purposive sampling technique in selecting the women with breast cancer in the intervention (47) and control (47) groups. Data on  QOL was measured using standardized instruments, namely the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-version 3 (EORTC QLQ-C30.

RESULTS

The results show the pre-intervention overall functional quality of life domain score was 59.2±21.98 for the intervention and 67.0± 20.13 for the control, an overall score for the symptom domain was 31.8±10.89 for the intervention and 29.8±10.24 for the control. The post-intervention overall generic functional domain score was 89.0±11.1 for the intervention and 51.2±17.8 for the control and for symptoms domain; their overall score was 16.4±10.2 for the intervention and 35.4±12.4 for the control. A significant difference existed  in all post-intervention  functional domain scores of the generic function and symptoms quality of life as the functional domains (p < 0.001) and global health status (p < 0.001).

CONCLUSION

As the numbers of women who survive breast cancer continue to increase, there is a need for lifestyle modification like exercise to improve and maintain their overall QOL to live a fulfilled life devoid of post-treatment complications.

The CADENCE pilot trial - Promoting physical activity in bladder cancer survivors: A protocol paper

Background

Participation in physical activity has been found to be beneficial for mental and physical health outcomes among cancer survivors. However, to date no intervention exists specifically to promote physical activity among bladder cancer survivors. In light of this knowledge a home-based exercise intervention was co-created for those recently diagnosed with bladder cancer.

Aim

The aim of the present study, financially supported by Action Bladder Cancer UK [1], is to pilot the home-based exercise intervention tailored specifically for bladder cancer survivors (i.e. from the point of diagnosis) to improve physical and mental health outcomes (during treatment and beyond) in this population.

Methods

This study will use a randomised controlled trial design. Arm one will consists of the 14 week home-based exercise intervention and arm two usual care (15 participants will be randomised to each arm). Baseline data collection will take place shortly after clinical diagnosis of bladder cancer, and follow-up approximately 7 weeks and then again approximately 14 weeks after commencement of the intervention. At each data collection point data will be collected from participants relating to demographics, physical and mental health. Participants will aslo be asked to wear an Actigraph Accelerometer at each data collection point for seven consecutive days. Immediately after baseline data collection participants in the intervention arm will be given the home-based exercise booklet.

Ethics and dissemination

Ethical approval was obtained for the present study via The London- City and East Research Ethics Committee (ID:291676). Results of this study will be disseminated through peer-reviewed publications and scientific presentations.

Neurocognitive and Behavioral Outcomes of Chinese Survivors of Childhood Lymphoblastic Leukemia

Background

Increasing attention has been dedicated to investigate modifiable risk factors of late effects in survivors of childhood cancer. This study aims to evaluate neurocognitive and behavioral functioning in a relatively young cohort of survivors of childhood acute lymphoblastic leukemia (ALL) in Hong Kong, and to identify clinical and socio-environmental factors associated with these outcomes.

Methods

This analysis included 152 survivors of childhood ALL who were ≥5 years post-diagnosis (52% male, mean [SD] age 23.5[7.2] years at evaluation, 17.2[7.6] years post-diagnosis). Survivors completed performance-based neurocognitive tests, and reported their emotional and behavioral symptoms using the Child/Adult Behavior Checklist. Socio-environmental variables (living space, fatigue, physical activity, family functioning, and academic stress) were self-reported using validated questionnaires. Clinical variables and chronic health conditions were extracted from medical charts. Multivariable linear modeling was conducted to test identify factors associated with neurocognitive/behavioral outcomes, adjusting for current age, sex, age at diagnosis and cranial radiation. An exploratory mediation analysis was performed to examine the mediating effects of risk factors on neurocognitive and behavioral outcomes.

Results

As compared to population norms, a minority of survivors developed mild-moderate impairment in motor processing speed (36.2%), memory (9.2%) and attention measures (4.0%-10.5%). Survivors also reported attention problems (12.5%), sluggish cognitive tempo (23.7%) and internalizing (depressive, anxiety and somatic symptoms) problems (17.1%). A minority of survivors developed mild-moderate treatment-related chronic conditions (n=37, 24.3%). As compared to survivors without chronic conditions, survivors with chronic conditions had more executive dysfunction (B=5.09, standard error [SE]=2.05; P=0.014) and reported more attention problems (B=5.73, SE=1.43; P<0.0001). Fatigue and poor family functioning was associated with multiple measures of behavior problems (all P<0.001). A lower level of physical activity was correlated with more self-reported symptoms of inattention (B= -1.12, SE=0.38, P=0.004) and sluggish cognitive tempo (B=-1.22, SE=0.41, P=0.003). Exploratory analysis showed that chronic health conditions were associated with behavioral measures through fatigue as the mediator.

Conclusion

The majority of young Chinese survivors of ALL had normal cognitive and behavioral function. Regular monitoring of behavioral function should be performed on survivors who develop treatment-related chronic conditions. Health behavior and socio-environment factors may be potentially modifiable risk factors associated with health outcomes in survivors.

Factors Influencing Exercise Following Pancreatic Tumor Resection

BACKGROUND

We previously demonstrated associations between exercise during pancreatic cancer treatment and quality of life and physical fitness prior to pancreatectomy. In this study, we quantified exercise among survivors following pancreatic tumor resection and characterized concordance with established guidelines.

METHODS

We quantified exercise frequency, duration, and intensity among survivors who underwent pancreatectomy for adenocarcinoma or a neuroendocrine tumor at our center from 2000 to 2017 and compared them with American College of Sports Medicine Guidelines for Cancer Survivors. Additional surveys measured motivation to exercise, barrier self-efficacy, quality of life, and fatigue. Multivariable models were constructed to evaluate associations between clinicodemographic and psychosocial variables and guideline concordance, and between guideline concordance and quality of life and fatigue.

RESULTS

Of 504 eligible survivors, 262 (52%) returned surveys. Only 62 participants (24%) reported meeting both aerobic and strengthening guidelines; 103 (39%) reported meeting neither. Adjusted analyses demonstrated that higher autonomous motivation was associated with higher aerobic and strengthening guideline concordance (both p < 0.01). Higher barrier self-efficacy and older age were associated with higher aerobic guideline concordance (p < 0.01). We identified no significant associations between guideline concordance and tumor type, time since surgery, or recent cancer therapy (all p > 0.05). We found favorable associations between aerobic guideline concordance and both quality of life and fatigue (both p < 0.001).

CONCLUSIONS

Less than one-quarter of participants exercised sufficiently to meet national exercise guidelines following pancreatectomy. To maximize exercise and related benefits, interventions should help survivors increase intrinsic motivation and overcome barriers to exercise.

Remote interventions to improve exercise behaviour in sedentary people living with and beyond cancer: a systematic review and meta-analysis

BACKGROUND

The COVID-19 pandemic has forced many cancer services to consider a transition to a remote format of delivery that is largely untested. Accordingly, we sought to perform a systematic review of the effects of remotely delivered interventions to improve exercise behaviour in sedentary adults living with and beyond cancer.

METHODS

Eligible studies were randomised controlled trials comparing a remotely delivered exercise intervention to a usual care comparison in sedentary people over 18 years old with a primary cancer diagnosis. Nine electronic databases were searched from inception to November 2020.

RESULTS

The review included three trials, totalling 186 participants. Two of the included trials incorporated prescriptions that meet current aerobic exercise recommendations, one of which also meets the guidelines for resistance exercise. No trials reported an intervention adherence of 75% or more for a set prescription that meets current exercise guidelines.

CONCLUSION

There is little evidence suggesting that remote exercise interventions promote exercise behaviours or improve physical function in sedentary adults living with and beyond cancer. The development and evaluation of novel remote exercise interventions is needed to establish their usefulness for clinical practice. Given the social response to the COVID-19 pandemic, further research in this area is urgently needed.

Physical Activity, Mental Health, and Technology Preferences to Support Cancer Survivors During the COVID-19 Pandemic: Cross-sectional Study

BACKGROUND

COVID-19 has had significant health-related and behavioral impacts worldwide. Cancer survivors (hereafter referred to as "survivors") are particularly prone to behavioral changes and are encouraged to be more vigilant and observe stricter social distancing measures.

OBJECTIVE

We explored (1) changes in physical activity and sedentary behaviors since the onset of COVID-19, along with changes in mental health status, and (2) alternative strategies to support survivors' physical activity and social health during and after COVID-19, along with the role of digital health in such strategies.

METHODS

A questionnaire was distributed among survivors participating (currently or previously) in the community-based physical activity program LIVESTRONG at the Young Men's Christian Association (YMCA), from 3 sites outside an urban area in Massachusetts. Questions addressed pre-COVID-19 vs current changes in physical activity and sedentary behavior. Anxiety and depression were assessed using the 2-item Generalized Anxiety Disorder scale (GAD-2) and 2-item Patient Health Questionnaire (PHQ-2), and scores ≥3 indicated a clinical diagnosis of anxiety or depression, respectively. Digital health preferences were assessed through closed-ended questions. Open-ended responses addressing other preferences for physical activity programs and social support were analyzed, coded, and categorized into themes.

RESULTS

Among 61 participants (mean age 62 [SD 10.4] years; females: 51/61 [83.6%]), 67.2% (n=41) reported decreased physical activity and 67.2% (n=41) reported prolonged sitting times since the onset of COVID-19. Further, 24.6% (n=15) and 26.2% (n=16) met the GAD-2 and PHQ-2 criteria for clinical anxiety and depression, respectively. All participants owned a cellphone; 90% (n=54) owned a smartphone. Preferences for physical activity programs (n=28) included three themes: (1) use of digital or remote platforms (Zoom, other online platforms, and video platforms), (2) specific activities and locations (eg, outdoor activities, walking, gardening, biking, and physical activities at the YMCA and at senior centers), and (3) importance of social support regardless of activity type (eg, time spent with family, friends, peers, or coaches). The survey revealed a mean score of 71.8 (SD 21.4; scale 0-100) for the importance of social support during physical activity programs. Social support preferences (n=15) revealed three themes: (1) support through remote platforms (eg, texting, Zoom, phone calls, emails, and Facebook), (2) tangible in-person support (YMCA and senior centers), and (3) social support with no specific platform (eg, small gatherings and family or friend visits).

CONCLUSIONS

Physical activity and mental health are critical factors for the quality of life of survivors, and interventions tailored to their activity preferences are necessary. Digital or remote physical activity programs with added social support may help address the ongoing needs of survivors during and after the pandemic.

Effects of Exercise in Patients Undergoing Chemotherapy for Head and Neck Cancer: A Pilot Randomized Controlled Trial

Background: Cisplatin administration may induce muscle atrophy, thereby reducing the fitness level of patients with head and neck cancer (HNC). To date, only animal studies have been conducted to test the effectiveness of exercise interventions in diminishing side effects of cisplatin. Aim: To determine whether exercise training improves physical fitness and health-related quality of life (HRQoL) in patients receiving chemotherapy for Head & Neck (H&N). Material and methods: This pilot-randomized controlled trial was conducted on 57 participants receiving chemotherapy for HNC. The participants were randomized into an exercise group and a control group. The exercise group received moderate-intensity combined aerobic, resistance and flexibility exercises three times a week for eight weeks during chemotherapy. The control group received no specific information regarding exercise. The outcome measures including body composition, muscle strength, balance, flexibility, cardiovascular fitness and health-related quality of life (HRQoL) were assessed at baseline and eight weeks following baseline. Results: The body composition (body fat percentage, p = 0.002; skeletal muscle percentage, p = 0.008), dynamic balance (p = 0.01), muscle strength (upper extremity, p = 0.037; lower extremity, p = 0.025) and HRQoL (p = 0.001) showed a significant difference between the exercise group and the control group eight weeks following baseline. Significant deteriorations were noted in flexibility, muscle strength, cardiovascular fitness and several domains of HRQoL scale in the control group at eight weeks following baseline. Conclusions: This study found that a combined aerobic, resistance and flexibility exercise program during chemotherapy may improve physical fitness (i.e., muscle strength, balance, flexibility and body composition) and HRQoL and alleviate the deterioration of cardiovascular fitness in patients with HNC. Further research studies with large sample sizes are warranted to investigate the long-term effects of exercise in this population.

An Evidence-Based Walking Program in Oregon Communities: Step It Up! Survivors

Physical activity can help mitigate the long-term symptoms and side effects of cancer and its treatment, but most cancer survivors are not active enough to achieve these benefits. An evidence-based strategy to promote physical activity among adults is a community group–based walking program. However, many evidence-based programs do not achieve intended population health outcomes because of the challenges of real-world implementation. We used the Interactive Systems Framework for Dissemination and Implementation to conceptualize implementation of a capacity-building intervention to support delivery of a community group–based walking program. We adapted an evidence-based guide for community group–based walking programs for cancer survivors and their support network. We provided a capacity-building intervention (technical assistance and small-grant funding) and evaluated this implementation intervention. We assessed effectiveness of the intervention by measuring adoption, acceptability, appropriateness, feasibility, fidelity, implementation costs, and penetration through monthly progress reports, site visit observations, interviews, and a final report. Eight organizations received a small grant and technical assistance and implemented Step It Up! Survivors (SIUS). SIUS helped cancer survivors increase their physical activity, establish social connections, and be part of a supportive environment. Despite receiving monthly technical assistance, some grantees experienced challenges in recruiting participants, developing community partnerships, and adhering to the prescribed implementation plan. Implementation facilitators included community partners and specific components (eg, incentives for participants, webinars). Organizations needed different amounts and types of assistance with adaptation and implementation. Overall fidelity to SIUS ranged from 64% to 88%. Some integrated SIUS within existing organizational programming for sustainability. The provision of funding and technical assistance was a successful implementation intervention. Our results suggest a need to better tailor technical assistance while organizations are in the process of adapting, implementing, and sustaining an evidence-based program in their local communities.

Nutraceuticals and Exercise against Muscle Wasting during Cancer Cachexia

Cancer cachexia (CC) is a debilitating multifactorial syndrome, involving progressive deterioration and functional impairment of skeletal muscles. It affects about 80% of patients with advanced cancer and causes premature death. No causal therapy is available against CC. In the last few decades, our understanding of the mechanisms contributing to muscle wasting during cancer has markedly increased. Both inflammation and oxidative stress (OS) alter anabolic and catabolic signaling pathways mostly culminating with muscle depletion. Several preclinical studies have emphasized the beneficial roles of several classes of nutraceuticals and modes of physical exercise, but their efficacy in CC patients remains scant. The route of nutraceutical administration is critical to increase its bioavailability and achieve the desired anti-cachexia effects. Accumulating evidence suggests that a single therapy may not be enough, and a bimodal intervention (nutraceuticals plus exercise) may be a more effective treatment for CC. This review focuses on the current state of the field on the role of inflammation and OS in the pathogenesis of muscle atrophy during CC, and how nutraceuticals and physical activity may act synergistically to limit muscle wasting and dysfunction.

Development of a pre- and postoperative physical activity promotion program integrated in the electronic health system of patients with bladder cancer (The POPEYE study): An intervention mapping approach

INTRODUCTION

Uptake of sufficient physical activity before and after radical cystectomy is important to improve physical and psychosocial outcomes in bladder cancer (BC) patients.

METHODS

In this paper, we describe the development of an evidence-based and theory-informed intervention, guided by the steps of the Intervention Mapping approach, to promote physical activity before and after radical cystectomy in patients with BC.

RESULTS

The intervention is a home-based physical activity program. The preoperative timeframe of the intervention is 4 or 12 weeks, depending on administration of neoadjuvant chemotherapy. Postoperatively, the intervention will last for 12 weeks. The intervention consists of a digital oncological platform (DOP), several consultations with healthcare professionals, personal booklet and follow-up phone calls. DOP includes information, diaries, visual representation of progress, mailbox, videos of peers and treating physician explaining the benefits of physical activity, photo material of exercises and a walking program with an activity tracker. Individual goals will be set and will be self-monitored by the patient through DOP. Patients will receive alerts and regular feedback.

CONCLUSIONS

Intervention Mapping ensures transparency of all intervention components and offers a useful approach for the development of behaviour change interventions for cancer patients and for translation of theories into practice.

Prevalence of lifestyle behaviors and associations with health-related quality of life among older female cancer survivors

PURPOSE

Healthy lifestyles including maintaining a normal weight, consuming a healthy diet, and being physically active can improve prognosis and health-related quality of life (HRQoL) among cancer survivors. The largest proportion of cancer survivors are older adults (≥ 65 years), yet their lifestyle behaviors are understudied. This study sought to examine the lifestyle behaviors (maintaining healthy weight, diet quality, physical activity) of older female cancer survivors and identify associations with HRQoL.

METHODS

Older female cancer survivors (n = 171) completed surveys to assess HRQoL (RAND-36), unintentional weight loss, body mass index (BMI), diet quality (HEI-2015), and physical activity. Demographic information and medical record data were also collected. Descriptive analyses, correlations, and stepwise linear regressions were utilized.

RESULTS

Physical and mental HRQoL of the sample (mean age = 74.50 years) were low: 41.94 ± 10.50 and 48.47 ± 7.18, respectively, out of 100. Physical activity was low: 75.3%, 54.2%, and 68.1% reported no strenuous, moderate, and mild physical activity, respectively. Mean BMI was 27.71 ± 6.24 (overweight) with 64% of the participants being overweight or obese. Mean HEI-2015 scores were 66.54 ± 10.0. Engagement in moderate physical activity was associated with higher physical HRQoL (β = 0.42, p = 0.004). Being white (β = 0.53, p < 0.001), older (β = 0.27, p = 0.025), and having higher HEI scores (β = 0.30, p = 0.011) were associated with higher mental HRQoL.

CONCLUSIONS

Older cancer survivors report poor diet quality, high rates of being overweight or obese, and low levels of physical activity that impact their HRQoL. Results indicate the need for tailored health coaching for older cancer survivors regarding their lifestyle behaviors to improve prognosis and HRQoL.

Rural-urban differences in meeting physical activity recommendations and health status in cancer survivors in central Pennsylvania

PURPOSE

This study explored rural-urban differences in meeting physical activity (PA) recommendations and health status in cancer survivors in central Pennsylvania and associations between PA and health status.

METHODS

Cancer survivors (N = 2463) were identified through a state cancer registry and mailed questionnaires assessing PA and health status. Rural-urban residence was based on county of residence at diagnosis. Participants self-reported frequency and duration of leisure-time PA and were classified as meeting: (1) aerobic recommendations (≥ 150 min/week), (2) muscle-strengthening recommendations (≥ 2 times/week), (3) both aerobic and muscle-strengthening recommendations, or (4) neither recommendation. Logistic regression models examined associations between rural-urban residence and meeting PA recommendations and associations between PA and health status, adjusting for age, cancer type, gender, and income.

RESULTS

Nearly 600 (N = 591, 24.0%) cancer survivors returned completed questionnaires (rural 9.5%, urban 90.5%). Half (50.0%) of rural cancer survivors reported no leisure-time PA compared to 35.2% of urban cancer survivors (p = 0.020), and urban cancer survivors were 2.6 times more likely to meet aerobic PA recommendations (95% CI 1.1-6.4). Odds of reporting good physical and mental health were 2.3 times higher among survivors who reported meeting aerobic recommendations compared to those who did not meet PA recommendations (95% CI 1.1-4.5), adjusting for rurality and covariates.

CONCLUSIONS

Results demonstrate persistent rural-urban differences in meeting PA recommendations in cancer survivors and its association with self-reported health.

IMPLICATIONS FOR CANCER SURVIVORS

Findings underscore the need for interventions to increase PA in rural cancer survivors in an effort to improve health status and reduce cancer health disparities.

Physical Activity and Cancer Care in the Atlantic Canadian Provinces: an Examination of Provider Beliefs, Practices, Resources, Barriers, and Enablers

Despite the well-established benefits of physical activity for cancer survivors, the vast majority of survivors are not sufficiently active to reap these benefits. While cancer-specific physical activity guidelines exist, it remains unclear whether there are sufficient resources to support these recommendations. The purpose of this qualitative study was to describe the available cancer-specific physical activity programs for cancer survivors in Atlantic Canada and explore barriers and enablers to program implementation. Interviews were conducted with a purposefully selected sample of oncology healthcare professionals, administrators, and cancer-specific physical activity program leaders to examine the attitudes and practices of key stakeholders with respect to physical activity and cancer-specific programming. Thirty participants, including 7 oncologists, 7 nurses, 6 allied healthcare professionals, 5 administrators, and 5 program leaders, completed an interview. Three over-arching themes emerged, including (1) knowledge, attitudes and need for physical activity; (2) implementation barriers; and (3) implementation enablers. The results of this study suggest that cancer survivors in Atlantic Canada may require additional resources and support with respect to physical activity throughout their cancer care journey.

Development and Evaluation of an Accelerometer-Based Protocol for Measuring Physical Activity Levels in Cancer Survivors: Development and Usability Study

Background

The collection of self-reported physical activity using validated questionnaires has known bias and measurement error.

Objective

Accelerometry, an objective measure of daily activity, increases the rigor and accuracy of physical activity measurements. Here, we describe the methodology and related protocols for accelerometry data collection and quality assurance using the Actigraph GT9X accelerometer data collection in a convenience sample of ovarian cancer survivors enrolled in GOG/NRG 0225, a 24-month randomized controlled trial of diet and physical activity intervention versus attention control.

Methods

From July 2015 to December 2019, accelerometers were mailed on 1337 separate occasions to 580 study participants to wear at 4 time points (baseline, 6, 12, and 24 months) for 7 consecutive days. Study staff contacted participants via telephone to confirm their availability to wear the accelerometers and reviewed instructions and procedures regarding the return of the accelerometers and assisted with any technology concerns.

Results

We evaluated factors associated with wear compliance, including activity tracking, use of a mobile app, and demographic characteristics with chi-square tests and logistic regression. Compliant data, defined as ≥4 consecutive days with ≥10 hours daily wear time, exceeded 90% at all study time points. Activity tracking, but no other characteristics, was significantly associated with compliant data at all time points (P<.001). This implementation of data collection through accelerometry provided highly compliant and usable activity data in women who recently completed treatment for ovarian cancer.

Conclusions

The high compliance and data quality associated with this protocol suggest that it could be disseminated to support researchers who seek to collect robust objective activity data in cancer survivors residing in a wide geographic area.

Health status, lifestyle habits, and perceived social support in long-term cancer survivors: a cross-sectional study

OBJECTIVE

To compare the presence of comorbidities and self-perceived health and social support between long-term cancer survivors and people without a history of cancer from a clinical trial examining the effects of a multiple risk behavior intervention.

RESULTS

Of the 4259 people studied, 190 (4.46%) were cancer survivors. They had a mean ± SD age of 62.8 ± 7 years vs. 58.7 ± 8 years (P < 0.01) for non-cancer people and were more likely to be on long-term sick leave (11.9 vs. 3.5%, P < 0.001). No differences were observed for smoking, adherence to the Mediterranean diet, physical activity, obesity, or social support. Cancer survivors were more likely to have worse self-perceived health (OR 1.82; 95% CI 1.02-2.75), more comorbidities (OR 1.68; 95% CI 1.18-2.39), COPD (OR 2.17; 95% CI 1.25-3.78), and depression (OR 1.65; 95% CI 1.06-2.57). Older age and worse self-perceived health were independent predictors of survivorship in the adjusted analysis.

Relationships Between Fear of Cancer Recurrence and Lifestyle Factors Among Cancer Survivors

We examine the relationships between fear of cancer recurrence (FCR), physical activity, smoking status, and engagement in healthier habits in a US population-based sample of post-treatment cancer survivors. We used data from the 2011 Medical Expenditure Panel Survey (MEPS) Experience with Cancer Survivorship Supplement. Multivariable logistic regression was used to test the relationship of FCR to physical activity, smoking status, and engagement in healthier habits. In all analyses, MEPS survey weights were applied to account for the survey design. Compared with those reporting no FCR, survivors reporting high FCR had significantly lower odds of reporting that they were not currently smokers (odds ratio [OR] = 0.46; 95% CI 0.24, 0.91) and those with any level of FCR had significantly higher odds of reporting healthier habits since diagnosis relative to those with no FCR (low FCR OR = 1.97; 95% CI 1.36, 2.85; high FCR OR = 2.40; 95% CI 1.33, 4.32). FCR was not associated with the odds of reporting physical activity. Findings from this large population-based survey suggest that some of survivors' lifestyle factors may be related to their level of FCR. Understanding the effects of FCR on lifestyle factors may help survivors, survivorship care providers, and policy makers better understand important differences among cancer survivors and personalize interventions in clinical care.

The Power of Phytochemicals Combination in Cancer Chemoprevention

Conventional therapies for cancer treatment have posed many challenges, including toxicity, multidrug resistance and economic expenses. In contrast, complementary alternative medicine (CAM), employing phytochemicals have recently received increased attention owing to their capability to modulate a myriad of molecular mechanisms with a less toxic effect. Increasing evidence from preclinical and clinical studies suggest that phytochemicals can favorably modulate several signaling pathways involved in cancer development and progression. Combinations of phytochemicals promote cell death, inhibit cell proliferation and invasion, sensitize cancerous cells, and boost the immune system, thus making them striking alternatives in cancer therapy. We previously investigated the effect of six phytochemicals (Indol-3-Carbinol, Resveratrol, C-phycocyanin, Isoflavone, Curcumin and Quercetin), at their bioavailable levels on breast cancer cell lines and were compared to primary cell lines over a period of 6 days. This study showed the compounds had a synergestic effect in inhibiting cell proliferation, reducing cellular migration and invasion, inducing both cell cycle arrest and apoptosis. Despite the vast number of basic science and preclinical cancer studies involving phytochemicals, the number of CAM clinical trials in cancer treatment still remains nascent. In this review, we summarize findings from preclinical and clinical studies, including our work involving use of phytochemicals, individually as well as in combination and further discuss the potential of these phytochemicals to pave way to integrate CAM in primary health care.

Targeted delivery of thermoresponsive polymeric nanoparticle-encapsulated lycopene: in vitro anticancer activity and chemopreventive effect on murine skin inflammation and tumorigenesis

Naturally occurring lycopene has been reported for its chemopreventive and chemotherapeutic efficiency in various cancers, but its exceptional lipophilicity, poor aqueous solubility, instability, and consequently poor bioavailability limit its usage as a chemopreventive and chemotherapeutic agent. The present study aimed to synthesize co-polymeric nanoparticle-encapsulated formulations of commercial lycopene (NLY) and extracted lycopene (NLX) and evaluate their in vitro anticancer activity and inhibitory effect on 12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted skin inflammation and tumorigenesis in Swiss albino mice. To prepare the nanoparticle-encapsulated formulations of lycopene, thermosensitive PNIPAAM-PEG-based co-polymeric nanoparticles were synthesized and characterized by FTIR spectroscopy, NMR spectroscopy, DLS, and TEM. Nanolycopene, unlike free lycopene, could be readily dispersed in aqueous media. Nanolycopene demonstrated stronger antioxidant activity and comparable in vitro anticancer efficacy to free lycopene against the melanoma cell line B16. Furthermore, nanolycopene showed comparable reduction of TPA-induced skin edema, expression of COX-2, and oxidative stress response. Additionally, it showed significant inhibition of tumor promotion. It also altered Bax and Bcl2 expressions, which led to the induction of apoptosis. The results also supported that the extracted lycopene-encapsulated nanoparticles may be a good alternative to the expensive commercial lycopene for cancer treatment.

Physical health composite and risk of cancer mortality in the REasons for Geographic and Racial Differences in Stroke Study

It is unclear how resting myocardial workload, as indexed by baseline measures of rate-pressure product (RPP) and physical activity (PA), is associated with the overall risk of cancer mortality. We performed prospective analyses among 28,810 men and women from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. We used a novel physical health (PH) composite index and categorized participants into one of four groups based on combinations from self-reported PA and RPP: 1) No PA and High RPP; 2) No PA and Low RPP; 3) Yes PA and High RPP; and 4) Yes PA and Low RPP. We examined the association between baseline PH composite and cancer mortality adjusted for potential confounders using Cox regression. A total of 1191 cancer deaths were observed over the 10-year observation period, with the majority being lung (26.87%) and gastrointestinal (21.49%) cancers. Even after controlling for sociodemographics, health behaviors, baseline comorbidity score, and medications, participants with No PA and High RPP had 71% greater risk of cancer mortality when compared to participants with PA and Low RPP (adjusted HR: 1.71, 95% CI: 1.42-2.06). These associations persisted after examining BMI, smoking, income, and gender as effect modifiers and all-cause mortality as a competing risk. Poorer physical health composite, including the novel RPP metric, was associated with a nearly 2-fold long-term risk of cancer mortality. The physical health composite has important public health implications as it provides a measure of risk beyond traditional measure of obesity and physical activity.

Precision Medicine in Lifestyle Medicine: The Way of the Future?

Precision medicine has captured the imagination of the medical community with visions of therapies precisely targeted to the specific individual's genetic, biological, social, and environmental profile. However, in practice it has become synonymous with genomic medicine. As such its successes have been limited, with poor predictive or clinical value for the majority of people. It adds little to lifestyle medicine, other than in establishing why a healthy lifestyle is effective in combatting chronic disease. The challenge of lifestyle medicine remains getting people to actually adopt, sustain, and naturalize a healthy lifestyle, and this will require an approach that treats the patient as a person with individual needs and providing them with suitable types of support. The future of lifestyle medicine is holistic and person-centered rather than technological.

Physical Activity: Impact on Survival in Gynecologic Cancer

Importance

Physical activity has many important health benefits. There is also growing evidence that physical activity plays a role in the prevention and prognosis of multiple cancers, including gynecologic malignancies. Despite the many benefits of physical activity, the number of individuals meeting physical activity recommendations remains low.

Objective

To examine the role that physical activity plays in the prevention, treatment, and prognosis of gynecologic malignancies and to review the feasibility of physical activity interventions among gynecologic cancer survivors.

Evidence Acquisition

A PubMed search was performed using relevant terms to identify journal articles related to the proposed subject. The websites of multiple national and international organizations were also used to obtain up-to-date guidelines and recommendations.

Results

Physical activity appears to decrease the risk of ovarian, endometrial, and cervical cancer, with the strongest evidence of this association seen in endometrial cancer. Although the literature is scarce, participation in physical activity is feasible during active treatment for gynecologic cancers and may decrease symptom burden and increase chemotherapy completion rates. Gynecologic cancer survivors are motivated to increase physical activity, and lifestyle intervention programs are feasible and well received among this population.

Conclusions and Relevance

Health care providers caring for women with gynecologic malignancies must counsel patients regarding the importance of physical activity. This should include a discussion of the health benefits and, specifically, the cancer-related benefits. A personalized approach to physical activity intervention is essential.

The Role of Technology in Adherence to Physical Activity Programs in Patients with Chronic Diseases Experiencing Fatigue: a Systematic Review

Background

The beneficial role of physical activity (PA) to manage the health condition of patients with chronic diseases is well known. However, adherence to PA guidelines in this group is still low. Monitoring and user-interface technology could represent a significant tool to increase exercise adherence to those particular groups who experience difficulties in adhering to regular and substantial physical activity, and could be supportive in increasing the success of PA programs and interventions. This systematic review aimed at evaluating the effect of physical activity monitoring technology in improving adherence to a PA program in patients with chronic diseases experiencing fatigue.

Methods

This systematic review was conducted according to PRISMA guidelines. The literature search was performed in Embase, Medline, Biosis, Scopus, and SPORTDiscus. We filtered the literature according to the question: “Does monitoring technology affect adherence to physical activity and exercise programs in patients with chronic diseases perceiving fatigue?”.

Results

The search resulted in 1790 hits; finally, eight studies were included, with a total number of 205 patients. Study quality was moderate except for one study of high quality. Only three disease types emerged, COPD, HF, and cancer. PA programs were rather short (from 8 to 13 weeks) except for one 3-year-long study. Five studies employed pedometers and two an activity monitor. Three studies based their adherence on steps, the remaining studies focused on active minutes. Adherence was explicitly reported in two studies, and otherwise derived. Four studies showed high adherence levels (85% week-10, 89% week-8, 81% week-13, 105% week-13, 83% average week-1–12) and three low levels (56% week-12, 41% year-2, 14 year-3).

Conclusion

The small number of studies identified did not allow to establish whether the use of monitoring technology could improve adherence to PA programs in patients with chronic diseases experiencing fatigue, but the current evidence seems to suggest that this is a field warranting further study, particularly into how monitoring technology can help to engage patients to adhere to PA programs.

Risk of comorbid cardiovascular disease in Korean long-term cancer survivors

BACKGROUND

Cardiovascular disease (CVD) is a common cause of death in cancer survivors. We evaluated the risk of comorbid CVD in long-term cancer survivors according to specific cancer site.

METHODS

Study subjects included 47,171 Koreans aged over 40 years who visited a health promotion centre between 2010 and 2012. Information on CVD and cancer was obtained from self-report. Comorbid CVD was defined as stroke, myocardial infarction or angina pectoris. The risk of comorbid CVD in survivors was compared with that in non-cancer subjects using multiple logistic regression analysis.

RESULTS

Among cancer survivors (n = 3,753), 330 events of CVD were reported. Age- and sex-adjusted analysis showed that odds ratio (OR) for comorbid CVD in survivors was 1.52 (95% confidence interval: 1.34-1.72) compared to non-cancer subjects (n = 43,418). After adjusting for health-related behaviour and medical history, only lung cancer survivors had 2.44 (1.01-5.89)-fold higher OR for CVD. In stratified analysis, significantly higher OR for CVD was evident in lung cancer survivors with hypertension who did not perform regular physical exercise.

CONCLUSIONS

Adult cancer survivors may have an increased risk of comorbid CVD that might be mediated in part by known cardiovascular risk factors depending on the specific cancer site.
