What is the role of physical exercise in the era of cancer prehabilitation? A systematic review.

PURPOSE: Exercise before surgery, as part of prehabilitation, aiming to enhance patients' functional and physiological capacity, has become widespread, necessitating an in-depth understanding. METHODS: A systematic search was conducted on Pubmed, Cochrane, and Scopus to examine the effect of exercise as prehabilitation, alone or in combination with other interventions, in patients with cancer. Interventional studies applying a single-arm, randomized controlled, or nonrandomized design were included. RESULTS: A total of 96 studies were included, and categorized according to cancer types, i.e., gynecological, breast, urological, gastrointestinal and lung cancer. For each cancer site, the effect of exercise, on physical fitness parameters and postoperative outcomes, including length of hospital stay and postoperative complications, was reported. CONCLUSION: Exercise as prehabilitation may have an important role in improving physical fitness, postoperative outcomes, and accelerating recovery, especially in certain types of malignancies.

Feasibility of a novel exercise program for patients with breast cancer offering different modalities and based on patient preference.

PURPOSE: Exercise improves quality of life and reduces the side effects of cancer therapies. Nevertheless, attendance to exercise programs remains a challenge for patients. This study explored the feasibility of an exercise program in which women with breast cancer may be allowed to choose among three exercise delivery modalities. METHODS: Forty-seven patients with breast cancer (stage I-IV) participated in a 12-week combined aerobic and resistance training program. The exercise modality was chosen by patients according to their preferences and needs among three options: the personal training program, the home-based program, or the group-based program. Exercise prescription was similar between the three modalities. Whereas the primary endpoint was feasibility, assessed through recruitment rate, attendance, adherence, dropout rate, tolerability, and safety, secondary endpoints included health-related skills and quality of life. RESULTS: Out of 47 recruited patients, 24 chose the home-based program, 19 the personal training program, and four the group-based program. Six dropouts (13%) were registered, and no severe adverse events were recorded. The median program attendance was 98% for personal training programs, 96% for home-based programs, and 100% for group-based programs, whereas compliance resulted in more than 90% in each modality. At postintervention, a significant increase in cardiorespiratory fitness, lower body flexibility, and body weight was observed. Different quality-of-life domains were improved following the intervention, including physical and social functioning, fatigue, and appetite loss. No significant changes in other parameters were detected. CONCLUSIONS: An exercise prescription based on a patient-preferred delivery modality showed high feasibility in women with breast cancer.

A Feasibility Study Investigating an Exercise Program in Metastatic Cancer Based on the Patient-Preferred Delivery Mode.

BACKGROUND: Feasibility of exercise in patients with metastatic cancer is still a challenge. This study aimed to determine the feasibility and preliminary efficacy of an exercise intervention based on a patient-preferred delivery mode in patients affected by metastatic cancer. MATERIALS AND METHODS: Forty-four patients with a confirmed diagnosis of metastatic cancer were recruited in a 3-month exercise program. Whereas the exercise program consisted of aerobic and resistance activities performed twice a week, the participants may choose the mode of delivery: home based, personal training, or group based. The primary endpoint was the feasibility, defined by recruitment rate, attendance, adherence, dropout rate, tolerability (comparing the session RPE with the target RPE), and safety (using the Common Terminology Criteria for Adverse Events, version 5.0). Secondary endpoints included cardiorespiratory fitness (six minutes walking test), muscle strength (handgrip strength test and isometric leg press test), flexibility (the back scratch and chair sit and reach tests), anthropometric parameters (body mass index and waist-hip ratio), quality of life (EORTC QLQ C-30 questionnaire), and amount of physical exercise (Godin's Shepard Leisure Time Exercise Questionnaire). Descriptive statistics, Student t test, and Wilcoxon signed rank test were used to analyze data. RESULTS: The study recruitment rate was 81%. Out of 44 recruited patients, 28 chose the personal training program, 16 chose the home-based program, and none chose the group-based program. Nine dropouts occurred (20%), 6 in the personal training program, and 3 in the home-based intervention. The median attendance rate was 92%, adherence was 88%, tolerability was 100%, and 9 nonsevere adverse events were registered during the exercise sessions. An increase in cardiorespiratory fitness (P < .001) and flexibility (P = .011 for chair sit and reach; P = .040 for back scratch) was observed at the end of the intervention, while no changes in anthropometric values and muscle strength were detected. Different quality-of-life domains were improved following the intervention, including physical (P = .002), emotional (P < .001), and role functioning (P = .018), fatigue (P = .030), and appetite loss (P = .005). CONCLUSION: A 3-month exercise program based on a patient-preferred delivery mode is feasible in patients with metastatic cancer and may improve physical function and quality of life. TRIAL REGISTRATION: NCT04226508.

Effect of exercise across the head and neck cancer continuum: a systematic review of randomized controlled trials.

PURPOSE: This study aims to systematically explore the impact of physical exercise as supportive therapy for head and neck cancer. METHODS: A systematic search on PubMed/MEDLINE, Cochrane, and SPORTDiscus was conducted. Randomized controlled trials exploring the effects of a physical exercise intervention in comparison with usual care on outcomes in patients with head and neck cancer were selected. The RoB 2 tool was used to determine the study quality. The extracted data are reported as qualitative synthesis. RESULTS: Among the 527 records examined, nine studies were included. No trials investigating exercise as prehabilitation were found, whereas eight studies involving 452 patients with head and neck cancer were conducted during anticancer treatment. Most trials did not report improvements in body mass index or body composition, while 2/4 and 3/5 investigations found a significant increase in muscle strength and cardiorespiratory fitness, respectively. Regarding the patients' reported outcomes, 4 out of 7 studies observed enhancements in some domains of quality of life, and two trials out of 3 detected an amelioration in fatigue following the exercise intervention. Analyzing the exercise programs, it seems that combining aerobic and resistance training could be more beneficial compared to a single type of full-body exercise in counteracting physical decline and controlling symptoms in the anticancer therapy phase. One trial has investigated the effect of resistance exercise on patients who had terminated the anticancer treatments, reporting significant improvements in lean mass, muscle strength, and quality of life. CONCLUSION: Exercise may be a promising approach in patients with head and neck cancer. Future studies are needed to consolidate these results.

Exploring the feasibility of a combined exercise program for patients with advanced lung or pancreatic cancer.

Objective: This study aims to assess the safety, feasibility, and potential benefits of a combined aerobic and resistance exercise intervention for patients diagnosed with advanced pancreatic or lung cancer. Methods: A prospective, single-arm study was conducted, enrolling patients with advanced lung or pancreatic cancer. Participants engaged in a 12-week exercise intervention comprising personalized bi-weekly aerobic and resistance training tailored to individual baseline conditions. The primary study outcomes focused on safety (absence of serious adverse events) and feasibility. Secondary outcomes included assessments of functional capacity using the "Six minutes walking test", strength measured through handgrip and leg press tests, anthropometric measures including body mass index and waist-hip ratio, quality of life (QoL), and changes in blood parameters. Results: The study involved twelve patients (mean age 57.66 â€‹± â€‹7.40 years), with seven having pancreatic cancer and five having lung cancer. The recruitment rate was 50%, and assessment adherence was 100%, with an 84% adherence to the exercise program and no dropouts. No exercise-related adverse events were recorded, while three non-severe, non-exercise-related adverse events were observed: treatment-related dermatitis (Grade 2), axillary lymphadenopathy (Grade 2), and migraine (Grade 1). Significant enhancements in functional capacity, emotional well-being, and social functioning within the QoL domains were observed. Anthropometric measures, specifically waist-hip ratio and body mass index, remained stable. Conclusions: The findings suggest that a tailored 12-week exercise intervention is both feasible and safe for patients with advanced lung or pancreatic cancer. This intervention appears to enhance functional capacity, specific aspects of QoL, and contribute to maintaining body weight.

Exercise and Bone Health in Cancer: Enemy or Ally?

Bone health is often threatened in cancer patients. Bone metastasis and osteoporosis frequently occur in patients with cancer and may lead to different skeletal-related events, which may negatively affect patients' quality of life and are associated with high mortality risk. Physical exercise has been recognized as a potential adjunctive strategy in the cancer setting to improve physical function as well as treatment-related side effects. Nevertheless, exercise is often not recommended to patients with bone health impairments due to safety concerns. In the current review, we aimed, through a comprehensive review of the evidence, to explore the impact of exercise in terms of safety profile, bone outcomes, and the effects on other outcomes in patients with cancer affected by bone metastasis or at high risk of losing bone. Additionally, we explored the potential mechanisms by which exercise may act on bone, particularly the impact of mechanical load on bone remodeling. Finally, considerations about exercise prescription and programming in these populations are also discussed.

Kinesiology Students' Perception Regarding Exercise Oncology: A Cross-Sectional Study.

Delivering physical activity in cancer care requires knowledge, competence, and specific skills to adapt the exercise program to the patients' specific needs. Kinesiology students could be one of the main stakeholders involved in the promotion of physical activity. This study aims to investigate the knowledge, perception, and competence about exercise in patients with oncological disease in a sample of students attending the Sports Science University. A total of 854 students (13% response rate) from four Italian universities completed the online survey between May and June 2021. About half of the study participants identified the correct amount of aerobic (44%) and strength (54%) activities proposed by the American College of Sports Medicine for patients with cancer. Almost all the students recognized the importance of physical activity in cancer prevention (96%), in the management of cancer before surgery (96%), during anticancer treatments (84%), and after therapies completion (98%). On the contrary, they reported a lack of university courses dedicated to cancer diseases, psychological implications, and prescription of physical activity in all types of cancer prevention. Overall, few students felt qualified in delivered counseling about physical activity and individual or group-based exercise programs in patients with cancer. Logistic regression revealed that the students attending the Master's Degree in Preventive and Adapted Physical Activity were more likely to have knowledge and competence than other students. The present study suggests that kinesiology universities should increase the classes and internships about exercise oncology to train experts with specific skills who are able to adequately support patients in their lifestyle modification.

Effect of exercise on functional capacity in patients with advanced cancer: A meta-analysis of randomized controlled trials.

PURPOSE: To determine the impact of exercise on functional capacity, measured through the "Six minutes walking test" (6MWT) in patients with advanced cancer stage. METHODS: Systematic research on PubMed, Cochrane Library, and SportDiscus was conducted. Randomized controlled trials were eligible if they examined the effect of exercise on 6MWT. RESULTS: Overall, a total of ten trials were included in the primary analysis. Compared to the controls, the exercise intervention was associated with an increase in functional capacity (+20.86 m; CI: -5.90 to 47.72, p = 0.12) although not reaching the statistical significance. Sensitivity analysis revealed an improvement for studies proposing a supervised exercise intervention towards the statistical significance. Few adverse events were associated with exercise training, and the median withdrawals rate was 17%. CONCLUSIONS: Exercise may have a beneficial role on functional capacity in patients with advanced cancer, especially if supervised.

Integrating supportive care into the multidisciplinary management of lung cancer: we can't wait any longer.

INTRODUCTION: Due to important achievements in terms of diagnostic and therapeutic tools and the complexity of the disease itself, lung cancer management needs a multidisciplinary approach. To date, the classical multidisciplinary team involves different healthcare providers mainly dedicated to lung cancer diagnosis and treatments. Nevertheless, the underlying disease and related treatments significantly impact on patient function and psychological well-being. In this sense, supportive care may offer the best approach to relieve and manage patient symptoms and treatment-related adverse events. AREAS COVERED: Evidence reports that exercise, nutrition, smoking cessation, and psychological well-being bring many benefits in patients with lung cancer, from both a physical and socio-psychological points of view, and potentially improving their survival. Nevertheless, supportive care is rarely offered to patients, and even less frequently these needs are discussed within the multidisciplinary meeting. EXPERT OPINION: Integrating supportive care as part of the standard multidisciplinary approach for lung cancer involves a series of challenges, the first one represented by the daily necessity of specialists, such as kinesiologists, dietitians, psycho-oncologists, able to deliver a personalized approach. In the era of precision medicine, this is an essential step forward to guarantee comprehensive and patient-centered care for all patients with lung cancer.
