Delivering adapted physical activity by videoconference to patients with fatigue under immune checkpoint inhibitors: Lessons learned from the PACTIMe-FEAS feasibility study

Crosstalk between Exercise and Immunotherapy: Current Understanding and Future Directions

Accumulated evidence highlights that exercise can modulate multiple cytokines, influencing transcriptional pathways, and reprogramming certain metabolic processes, ultimately promoting antitumor immunity and enhancing the efficacy of immune checkpoint inhibitors in cancer patients. Exploring the mechanisms behind this will, for one thing, help us uncover key factors and pathways in exercise-assisted cancer immunotherapy, offering more possibilities for future treatment methods. For another, it will support the development of more personalized and effective exercise prescriptions, thereby improving the prognosis of cancer patients.

Virtually Supervised Exercise Programs for People With Cancer: A Scoping Review

BACKGROUND

Exercise has been shown to improve physical function and quality of life for individuals with cancer. However, low rates of exercise adoption and commonly reported barriers to accessing exercise programming have demonstrated a need for virtual exercise programming in lieu of traditional in-person formats.

OBJECTIVE

The aim of this study was to summarize the existing research on supervised exercise interventions delivered virtually for individuals living with and beyond cancer.

METHODS

We conducted a scoping review of randomized controlled trials, pilot studies, or feasibility studies investigating virtually supervised exercise interventions for adults either during or after treatment of cancer. The search included EMBASE, MEDLINE, CINAHL, SPORTDiscus, Cochrane Library, and conference abstracts.

RESULTS

Fifteen studies were included. The interventions were delivered mostly over Zoom in a group format, with various combinations of aerobic and resistance exercises. Attendance ranged from 78% to 100%, attrition ranged from 0% to 29%, and satisfaction ranged from 94% to 100%. No major adverse events were reported, and only 3 studies reported minor adverse events. Significant improvements were seen in upper and lower body strength, endurance, pain, fatigue, and emotional well-being.

CONCLUSION

Supervised exercise interventions delivered virtually are feasible and may improve physical function for individuals with cancer. The supervision included in these virtual programs promoted similar safety as seen with in-person programming. More randomized controlled trials with large cohorts are needed to validate these findings.

IMPLICATIONS FOR PRACTICE

Individuals living with and beyond cancer can be encouraged to join virtually supervised exercise programs because they are safe, well enjoyed, and may improve physical function and quality of life.

Conditions for adherence to videoconference-based programs promoting adapted physical activity in cancer patients: a realist evaluation

BACKGROUND

Although moderate physical activity (PA) during cancer treatment has been associated with improved quality of life, reduced side effects, and even lower mortality, many barriers to successful implementation remain. Digital technology has been perceived as an effective lever for overcoming access and motivational issues but few studies have been performed to confirm this assumption. The "VISIO-AJUST" study explored the factors affecting the conditions of adherence to video-conference-based PA programs in patients undergoing cancer treatment.

METHODS

The VISIO-AJUST study was based on a qualitative successive case approach, guided by the principles of the realist evaluation, and applied to two French programs of PA, following three main steps: (1) Identification of factors likely to influence conditions of patients' adherence; (2) Elaboration and testing of explanatory "Context-Mechanism-Outcome (CMO)" configurations; (3) Refinement of CMO configurations, in order to understand what, how, for whom, and under what circumstances video-conference-based PA programs work.

RESULTS

Five main CMO configurations were found to be associated with adherence to video-conferencing-based PA programs, promoting (i) accessibility and a supportive environment for adapted physical activity, (ii) a setting conducive to sociability despite distance, (iii) Confidence and security of practice, (iv) a combination of several motivational levers in favor of continuity of effort and progress, (v) regularity of the sessions, progressiveness in the effort and evaluation of progress as a basis for the adoption of a regular physical practice.

CONCLUSION

This study provides original insights into the use of videoconferencing to enable patients to improve their PA during cancer treatment. Future research with long-term follow-up would allow for a better understanding of the key conditions promoting sustainable behavior change.

Effects of a physical activity and endometriosis-based education program delivered by videoconference on endometriosis symptoms: the CRESCENDO program (inCRease physical Exercise and Sport to Combat ENDOmetriosis) protocol study

BACKGROUND

Endometriosis is a chronic disease characterized by growth of endometrial tissue outside the uterine cavity which could affect 200 million women (The term "woman" is used for convenience. Individuals gendered as man or as nonbinary can also suffer from this disease) worldwide. One of the most common symptoms of endometriosis is pelvic chronic pain associated with fatigue. This pain can cause psychological distress and interpersonal difficulties. As for several chronic diseases, adapted physical activity could help to manage the physical and psychological symptoms. The present study will investigate the effects of a videoconference-based adapted physical activity combined with endometriosis-based education program on quality of life, pain, fatigue, and other psychological symptoms and on physical activity.

METHODS

This multicentric randomized-controlled trial will propose to 200 patients with endometriosis to be part of a trial which includes a 6-month program with 45 min to more than 120 min a week of adapted physical activity and/or 12 sessions of endometriosis-based education program. Effects of the program will be compared to a control group in which patients will be placed on a waiting list. All participants will be followed up 3 and 6 months after the intervention. None of the participants will be blind to the allocated trial arm. The primary outcome measure will be quality of life. Secondary outcomes will include endometriosis-related perceived pain, fatigue, physical activity, and also self-image, stereotypes, motivational variables, perceived support, kinesiophobia, basic psychological need related to physical activity, and physical activity barriers. General linear models and multilevel models will be performed. Predictor, moderator, and mediator variables will be investigated.

DISCUSSION

This study is one of the first trials to test the effects of a combined adapted physical activity and education program for improving endometriosis symptoms and physical activity. The results will help to improve care for patients with endometriosis.

Can Exercise Enhance the Efficacy of Checkpoint Inhibition by Modulating Anti-Tumor Immunity?

Immune checkpoint inhibition (ICI) has revolutionized cancer therapy. However, response to ICI is often limited to selected subsets of patients or not durable. Tumors that are non-responsive to checkpoint inhibition are characterized by low anti-tumoral immune cell infiltration and a highly immunosuppressive tumor microenvironment. Exercise is known to promote immune cell circulation and improve immunosurveillance. Results of recent studies indicate that physical activity can induce mobilization and redistribution of immune cells towards the tumor microenvironment (TME) and therefore enhance anti-tumor immunity. This suggests a favorable impact of exercise on the efficacy of ICI. Our review delivers insight into possible molecular mechanisms of the crosstalk between muscle, tumor, and immune cells. It summarizes current data on exercise-induced effects on anti-tumor immunity and ICI in mice and men. We consider preclinical and clinical study design challenges and discuss the role of cancer type, exercise frequency, intensity, time, and type (FITT) and immune sensitivity as critical factors for exercise-induced impact on cancer immunosurveillance.

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.

Is There a Role for Exercise When Treating Patients with Cancer with Immune Checkpoint Inhibitors? A Scoping Review

The impact of using exercise as a non-pharmacological intervention in patients with cancer receiving immune checkpoint inhibitors (ICIs) is not well known. Our objective was to determine the extent of, and identify gaps within, available literature addressing the effect of exercise on (a) oncological outcomes and (b) quality of life (QoL) in patients with cancer receiving ICIs, and (c) the underlying biological mechanisms for such effects. We conducted searches across EMBASE, APA PsycInfo and Ovid MEDLINE(R). Studies were eligible if they addressed at least one aspect of the objective and were available in the English language. Results were synthesised using a narrative approach and subsequently discussed with multidisciplinary stakeholders. As of the final search on 5 April 2022, 11 eligible studies were identified, of which 8 were preclinical and 3 were clinical. Clinical studies only focused on QoL-related outcomes. When studies were grouped by whether they addressed oncological outcomes (n = 7), QoL (n = 5) or biological mechanisms (n = 7), they were found to be heterogeneous in methodology and findings. Additional evidence, particularly in the clinical setting, is required before robust recommendations about whether, and how, to include exercise alongside ICI treatment can be made.
