Supports and Barriers to Home-Based Physical Activity During Preoperative Treatment of Pancreatic Cancer: A Mixed-Methods Study

Experiences of Patients with Breast Cancer Participating in a Prehabilitation Program: A Qualitative Study

Background: Breast cancer (BC) is the most prevalent cancer diagnosis among women worldwide. Several randomized controlled trials and systematic reviews have shown the benefits of exercise before, during, and after cancer treatment to manage side effects related to cancer and its therapies. However, these are poorly implemented across the disease-span, specifically, during the preoperative setting. Methods: Patients diagnosed with BC and participating in a randomized controlled trial on the effects of a prehabilitation program based on Nordic walking, muscle strengthening, and therapeutic education were invited to participate in this qualitative substudy. Two groups of eight patients each were recorded, transcript and analyzed using a specialized software (Atlas-Ti®, version 24). Results: During the axial codification phase, 22 unique codes and 6 main themes were identified related to their experience with the program, namely, (1) information received prior to participating; (2) motivation to participate; (3) barriers; (4) facilitators; (5) perceived degree of support from healthcare workers as well as peers; and (6) satisfaction with the characteristics of the prehabilitation program. Conclusions: Patients interviewed showed great interest in prehabilitation as a way to prepare both physically and mentally for surgery. In order to implement these interventions, healthcare systems need to acknowledge barriers and facilitators as well as the need for these programs to be supervised and monitored to avoid adverse events.

Effects of a Pragmatic Home-based Exercise Program Concurrent With Neoadjuvant Therapy on Physical Function of Patients With Pancreatic Cancer: The PancFit Randomized Clinical Trial

OBJECTIVE

To determine the effects of a preoperative, home-based exercise program on fitness and physical function in patients with pancreatic cancer.

BACKGROUND

We previously established a well-tolerated preoperative exercise program after finding a high frequency of sarcopenia and frailty in patients with pancreatic cancer.

METHODS

In this randomized, controlled trial (NCT03187951), patients with pancreatic cancer were randomized to Arm A: enhanced usual care or Arm B: prescribed aerobic and resistance exercise during neoadjuvant therapy. Patients received nutrition counseling and activity trackers. The primary endpoint was a 6-minute walk distance (6MWD; ≥14 meters improvement was clinically meaningful). Secondary endpoints included additional physical function tests, health-related quality of life, and clinical outcomes.

RESULTS

One hundred fifty-one patients were randomized. Objectively measured weekly activity (153.2±135.6 and 159.8±122.8 min in Arm A and B, respectively, P =0.62) and self-reported weekly moderate-to-strenuous physical activity (107.4±160.4 and 129.6±161.6 min in Arm A and Arm B, respectively, P =0.49) were similar, but weekly strength training sessions increased more in Arm B (by 1.8±1.8 vs 0.1±2.4 sessions, P <0.001). 6MWD improved in both Arm A (mean change 18.6±56.8 m, P =0.01) and Arm B (27.3±68.1 m, P =0.002). Quality of life and clinical outcomes did not significantly differ between arms. Pooling patients in both study groups, exercise, and physical activity was favorably associated with physical performance and clinical outcomes.

CONCLUSIONS

In this randomized trial of prescribed exercise versus enhanced usual care during neoadjuvant therapy for pancreatic cancer, a high volume of physical activity and increased exercise capacity were observed in both arms, highlighting the importance of activity among patients preparing for surgery.

What moves patients to participate in prehabilitation before major surgery? A mixed methods systematic review

BACKGROUND

Prehabilitation offers patients the opportunity to actively participate in their perioperative care by preparing themselves for their upcoming surgery. Experiencing barriers may lead to non-participation, which can result in a reduced functional capacity, delayed post-operative recovery and higher healthcare costs. Insight in the barriers and facilitators to participation in prehabilitation can inform further development and implementation of prehabilitation. The aim of this review was to identify patient-experienced barriers and facilitators for participation in prehabilitation.

METHODS

For this mixed methods systematic review, articles were searched in PubMed, EMBASE and CINAHL. Articles were eligible for inclusion if they contained data on patient-reported barriers and facilitators to participation in prehabilitation in adults undergoing major surgery. Following database search, and title and abstract screening, full text articles were screened for eligibility and quality was assessed using the Mixed Method Appraisal Tool. Relevant data from the included studies were extracted, coded and categorized into themes, using an inductive approach. Based on these themes, the Capability, Opportunity, Motivation, Behaviour (COM-B) model was chosen to classify the identified themes.

RESULTS

Three quantitative, 14 qualitative and 6 mixed methods studies, published between 2007 and 2022, were included in this review. A multitude of factors were identified across the different COM-B components. Barriers included lack of knowledge of the benefits of prehabilitation and not prioritizing prehabilitation over other commitments (psychological capability), physical symptoms and comorbidities (physical capability), lack of time and limited financial capacity (physical opportunity), lack of social support (social opportunity), anxiety and stress (automatic motivation) and previous experiences and feeling too fit for prehabilitation (reflective motivation). Facilitators included knowledge of the benefits of prehabilitation (psychological capability), having access to resources (physical opportunity), social support and encouragement by a health care professional (social support), feeling a sense of control (automatic motivation) and beliefs in own abilities (reflective motivation).

CONCLUSIONS

A large number of barriers and facilitators, influencing participation in prehabilitation, were found across all six COM-B components. To reach all patients and to tailor prehabilitation to the patient's needs and preferences, it is important to take into account patients' capability, opportunity and motivation.

Evaluation of a Virtual Dance Class for Cancer Patients and Their Partners during the Corona Pandemic-A Real-World Observational Study

BACKGROUND

During the corona pandemic, all courses on physical activity for cancer patients were canceled. The aim of our study was to evaluate the feasibility of switching dancing classes for patients and their partners to online classes.

METHODS

Patients and partners from courses at four different locations who consented to the online course offer were asked to fill in a pseudonymous questionnaire on access to the training, technical challenges, acceptance and well-being (1-item visual analog scale from 1 to 10) before and after the training.

RESULTS

Sixty-five participants returned the questionnaire (39 patients and 23 partners). Fifty-eight (89.2%) had danced before, and forty-eight (73.8%) had visited at least one course of ballroom dancing for cancer patients before. The first access to the online platform was difficult for 39 participants (60%). Most participants (57; 87.7%) enjoyed the online classes, but 53 (81.5%) rated them as less fun than the real classes as direct contact was missing. Well-being increased significantly after the lesson and remained improved for several days.

CONCLUSION

Transforming a dancing class is feasible for participants with digital experience and goes along with technical difficulties. It is a substitute for real classes if mandatory and improves well-being.

Bridging the Built and Social Environments: A Systematic Review of Studies Investigating Influences on Physical Activity

BACKGROUND

The purpose of this review was to examine articles assessing aspects of the built and social environment simultaneously, and how these environments influence physical activity (PA). A thorough review of studies is needed to identify patterns across studies and gaps for future research and practice.

METHODS

To be included, articles needed to contain: (1) self-report or objective measure of PA; (2) a measure of the built environment; (3) a measure of the social environment; and (4) an analysis between built environment, social environment, and PA. A systematic literature search of 4358 articles resulted in 87 articles.

RESULTS

Several populations were present within the sample including various age groups and different countries. As previously established, the built environment and social environment were consistently associated with PA; however, mediating factors between these 2 layers were less clear. Further, there was a lack of longitudinal and experimental study designs.

CONCLUSIONS

Results suggest a need for longitudinal and experimental designs with validated and granular measures. As communities recover from the COVID-19 pandemic, a thorough understanding of how built environment factors enhance or detract from social connectedness and how this reciprocal relationship impacts PA behavior is needed for future policy, environment, and systematic change.

Telemedicine and Pancreatic Cancer: A Systematic Review

Introduction: Pancreatic cancer requires a multidisciplinary approach in a high-volume center for all the steps of the diagnostic-therapeutic course. However, the most experienced centers are not evenly distributed throughout the country causing a real "health migration" that involves patients and families with relevant economic, time, and energy costs to bear. The COVID-19 pandemic had a deep impact on surgical and oncological care and the travel limits due to COVID-related restrictions, have delayed the care of cancer patient living far from the referral centers. In this scenario, several telemedicine approaches have been proposed to reduce the distance between clinicians and patients and to allow a fast and effective access to care even for patients distant from referral centers. The aim of the study is to analyze the evidence and describe the current utility of telemedicine tool for patients with pancreatic cancer. Methods: We systematically searched the literature in the following databases: Web of Science, PubMed, Scopus, and MEDLINE. The inclusion criteria were article describing a telemedicine intervention (virtual visits, telephone follow-up/counseling, mobile or online apps, telemonitoring) and focusing on adult patients with pancreatic cancer at any stage of the disease. Results: In total, 846 titles/abstracts were identified. Following quality assessment, the review included 40 studies. Telemedicine has been proposed in multiple clinical settings, demonstrating high levels of patient and health professional satisfaction. Conclusion: Successful telemedicine applications in patients with pancreatic cancer are telerehabilitation and nutritional assessment, remote symptom control, teledischarge after pancreatic surgery, tele-education and medical mentoring regarding pancreatic disease as well as telepathology.

A Study about a New Standardized Method of Home-Based Exercise in Elderly People Aged 65 and Older to Improve Motor Abilities and Well-Being: Feasibility, Functional Abilities and Strength Improvements

BACKGROUND

To verify the effects in terms of feasibility, strength and functional abilities of a standardized exercise training method that is partially supported (home training), with the aim of improving motor abilities and well-being.

METHODS

A total of 67 participants underwent two sessions per week for 12 weeks for the program, based on 8 sequences with specific body part targets, with each sequence made up of 9 exercises.

OUTCOME MEASURES

Recording of training session data, Chair Test, Hand Grip Test, Timed Up-and-Go Test, Stork Balance Test, Sit-and-Reach Test, VAS, Perceived Physical Exertion.

RESULTS

In total, 97% of the sample were "adherent" (more than 70% of the prescribed treatments performed). The rate of adverse events was infrequent (only 8). Chair Test +31%, Hand Grip Test +6%, Timed Up-and-Go Test -17%, Stork Balance Test +65%, Sit-and-Reach Test +55%, VAS -34%, Perceived Physical Exertion -69%.

CONCLUSIONS

Home training has good feasibility (adherence, tolerability, safety) and cost-effectiveness ratio and improves both strength and functional abilities, which, in turns, helps to improve motor abilities and well-being.

Factors predicting gains in moderate-to-vigorous physical activity in prostate cancer survivors on androgen deprivation therapy

BACKGROUND

Whether individual, environmental, and psychosocial factors predict changes in moderate-to-vigorous physical activity (MVPA) is poorly addressed in prostate cancer (PC) survivors undergoing androgen deprivation therapy (ADT).

PURPOSE

This secondary analysis of a randomized controlled trial examined changes in MVPA following a supervised personal training (PT), supervised group-based (GROUP) program, or a home-based, smartphone-assisted exercise (HOME) intervention in PC survivors on ADT and explored individual, environmental, and psychosocial predictors of MVPA.

METHODS

PC survivors on ADT underwent aerobic and resistance training for 6 months via PT, GROUP, or HOME. MVPA was captured via accelerometers and the Godin Leisure-Time Exercise Questionnaire. Changes in MVPA between groups were assessed using linear regression. The following predictors of MVPA were examined using Spearman correlations: the Neighborhood Environment Walkability Scale (NEWS); the Planning, Attitudes, and Behaviours (PAB) scale; the Relatedness to Others in Physical Activity Scale (ROPAS); and individual factors at baseline.

RESULTS

Participants (n = 37) were 69.4 ± 6.5 years old and 78.4% were on ADT for ≥ 3 months. Changes in accelerometry-based bouts and MVPA as well as self-reported MVPA did not differ between groups at 6 months. The Aesthetics domain of the NEWS questionnaire at baseline was the strongest predictor of positive MVPA changes (r = .66). Attitude (r = .64), planning (r = .57), and motivation (r = .50) at baseline were also predictive of engaging in higher MVPA throughout the intervention.

CONCLUSION

Changes in objective MVPA were modest. Additional emphasis on specific psychosocial and individual factors is important to inform theory-based interventions that can foster PA behavior change in PC survivors on ADT. Registration # NCT02046837.

A review of physical activity in pancreatic ductal adenocarcinoma: Epidemiology, intervention, animal models, and clinical trials

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest types of cancer, and the increasing incidence of PDAC may be related to the prevalence of obesity. Physical activity (PA), a method known to mitigate obesity by increasing total energy expenditure, also modifies multiple cellular pathways associated with cancer hallmarks. Epidemiologic evidence has shown that PA can lower the risk of developing a variety of cancers, reduce some of the detrimental side effects of treatments, and improve patient's quality of life during cancer treatment. However, little is known about the pathways underlying the correlations observed between PA interventions and PDAC. Moreover, there is no standard dose of PA intervention that is ideal for PDAC prevention or as an adjuvant of cancer treatments. In this review, we summarize relevant literature showing how PDAC patients can benefit from PA, the potential of PA as an adjuvant treatment for PDAC, the studies using preclinical models of PDAC to study PA, and the clinical trials to date assessing the effects of PA in PDAC.

A Mobile App With Multimodality Prehabilitation Programs for Patients Awaiting Elective Surgery: Development and Usability Study

Background

Complying with a prehabilitation program is difficult for patients who will undergo surgery, owing to transportation challenges and a limited intervention time window. Mobile health (mHealth) using smartphone apps has the potential to remove barriers and improve the effectiveness of prehabilitation.

Objective

This study aimed to develop a mobile app as a tool for facilitating a multidisciplinary prehabilitation protocol involving blood flow restriction training and sport nutrition supplementation.

Methods

The app was developed using “Appy Pie,” a noncoding app development platform. The development process included three stages: (1) determination of principles and requirements of the app through prehabilitation research team meetings; (2) app prototype design using the Appy Pie platform; and (3) app evaluation by clinicians and exercise and fitness specialists, technical professionals from Appy Pie, and non–team-member users.

Results

We developed a prototype of the app with the core focus on a multidisciplinary prehabilitation program with accessory features to improve engagement and adherence to the mHealth intervention as well as research-focused features to evaluate the effects of the program on frailty status, health-related quality of life, and anxiety level among patients awaiting elective surgery. Evaluations by research members and random users (n=8) were consistently positive.

Conclusions

This mobile app has great potential for improving and evaluating the effectiveness of the multidisciplinary prehabilitation intervention in the format of mHealth in future.

Physical Activity: A Feasibility Study on Exercise in Men Newly Diagnosed With Prostate Cancer

BACKGROUND

Physical activity (PA) has been shown to improve patient-centered care for cancer-related symptoms, treatment-related side effects, and health-related quality of life.

OBJECTIVES

This feasibility study aimed to explore PA preferences and changes in functional capacity and symptoms during a two-week self-prescribed PA intervention prior to treatment in men newly diagnosed with prostate cancer.

METHODS

Men newly diagnosed with prostate cancer were recruited from a community hospital, part of an academic comprehensive cancer center in the southeastern United States. An individualized PA intervention prescription was developed using baseline measures. Baseline and two-week measures consisted of functional capacity, PA participation, and symptom impact. Descriptive statistics and t tests were used.

FINDINGS

Thirteen men aged an average of 66.14 years (SD = 6.82) participated. Participants significantly improved functional capacity. Most common PAs were walking (n = 9) and yard work (n = 6).

PREsurgery thoughts - thoughts on prehabilitation in oncologic gynecologic surgery, a qualitative template analysis in older adults and their healthcare professionals

PURPOSE

This study aimed to reveal information that can be used for composing a prehabilitation program tailored to elderly gynecological oncological patients and is applicable to healthcare professionals. We investigated possible content and indications for prehabilitation, and what potential barriers might exist.

MATERIALS AND METHODS

Because of the primary exploratory study aim, inductive thematic template analysis on semi-structured interviews with gynecologic oncological patients aged ≥60 years and healthcare professionals were used.

RESULTS

16 patients and 20 healthcare professionals were interviewed. Three themes important for prehabilitation were found: (1) "Motivation," (2) "Practical issues and facilitators," and (3) "Patient-related factors." A short time interval between diagnosis and surgery was reported as a potential barrier for prehabilitation. Given components for a tailor-made prehabilitation program are: (1) The first contact with a nurse who screens the patients, gives tailor-made advice on prehabilitation and keeps patients motivated and supports them mentally; (2) If patients are referred to a more extensive/supervised program, this should preferably be arranged close to a patients' home.

CONCLUSION

Based on our findings, an outline of a patient-tailored prehabilitation program was developed. The main important themes for prehabilitation were "Motivation," "Practical issues and facilitators," and "Patient-related factors."IMPLICATIONS FOR REHABILITATIONPatients and healthcare professionals are positive about prehabilitation.Main themes for designing a prehabilitation program are "Motivation," "Practical issues and facilitators," and "Patient-related factors."Nursing staff can play a key role in prehabilitation.It is important to screen patients for specific impairments to obtain a tailor-made prehabilitation program.For some patients, general advice on prehabilitation might be sufficient, while others may need more supervision.The time interval between diagnosis and surgery is often short and is perceived as a potentially significant barrier for an effective prehabilitation program.

The Role of Home-Based Exercise in Maintaining Skeletal Muscle During Preoperative Pancreatic Cancer Treatment

Loss of skeletal muscle and inferior muscle quality are associated with poor prognosis in patients undergoing preoperative treatment for pancreatic cancer, so maintaining skeletal muscle health before surgery may help accelerate patients' functional recovery and improve their quality of life following surgery. While exercise helps maintain or increase skeletal muscle in individuals undergoing cancer treatment, its efficacy during pancreatic cancer treatment is unclear. Accordingly, in this study we compared changes in skeletal muscle quantity (skeletal muscle index [SMI]) and quality (skeletal muscle density [SMD]) during preoperative pancreatic cancer treatment in participants in a home-based exercise program (EP) and a historical cohort of patients who received the usual care (UC) with no formal exercise programming. Recommendations for the EP cohort included both aerobic and resistance exercise. We assessed changes in SMI and SMD using computed tomography scans administered at treatment planning (T0, prior to EP enrollment) and preoperative restaging (T1) for 33 EP and 64 UC patients and compared changes between groups. The UC patients had statistically significant SMI decreases from T0 to T1 (-1.4 ± 3.8 cm²/m²; p = .005), while the EP patients did not (0.2 ± 3.2 cm²/m²; p = .7). The SMI loss was significantly worse for the UC than for the EP patients (p = .03). Neither group demonstrated statistically significant changes in SMD from T0 to T1, nor did the groups differ in the amount of change in SMD. An adjusted linear regression model demonstrated that EP participation was significantly associated with better SMI maintenance (p = .02). These results suggest that participation in a home-based EP during preoperative treatment may help improve skeletal muscle health and clinical and quality of life outcomes for pancreatic cancer 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.

Home-Based Exercise Prehabilitation During Preoperative Treatment for Pancreatic Cancer Is Associated With Improvement in Physical Function and Quality of Life

Purpose: To investigate relationships among physical activity, changes in physical function, and health-related quality of life (HRQOL) among patients with pancreatic adenocarcinoma enrolled in a home-based exercise prehabilitation program. Methods: Patients with resectable pancreatic adenocarcinoma receiving preoperative chemotherapy and/or chemoradiation were enrolled on this prospective, single-arm trial and were advised to perform ≥60 minutes each of moderate-intensity aerobic exercise and strengthening exercise weekly. Activity was measured via self-report and accelerometers, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary activity (SA). Physical function measures at baseline and restaging follow-up included 6-minute walk test (6MWT), 5 times sit-to-stand (5×STS), handgrip strength (HGS), 3-m walk for gait speed (GS), and the PROMIS Physical Function Short Form. HRQOL was measured via the FACT-Hep questionnaire. Results: Fifty participants with mean age 66 years (standard deviation = 8 years) were enrolled. The 6MWT, 5×STS, and GS significantly improved from baseline to restaging follow-up (P=.001, P=.049, and P=.009, respectively). Increases in self-reported aerobic exercise, weekly MVPA, and LPA were associated with improvement in 6MWT (β=.19, P=.048; β=.18, P=.03; and β=.08, P=.03, respectively) and self-reported physical functioning (β=.02, P=.03; β=.03, P=.005; and β=.01, P=.02, respectively). Increased weekly LPA was associated with increased HRQOL (β=.03, P=.02). Increased SA was associated with decreased HRQOL (β=-.02,P=.01). Conclusions: Patients with potentially resectable pancreatic cancer exhibit meaningful improvement in physical function with prehabilitation; physical activity was associated with improved physical function and HRQOL. These data highlight the importance of physical activity during treatment for pancreatic cancer.
