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

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 ​± ​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.

Feasibility of home-based exercise training during adjuvant treatment for metastatic castrate-resistant prostate cancer patients treated with an androgen receptor pathway inhibitor (EXACT)

BACKGROUND

Exercise is an effective adjuvant therapy that can alleviate treatment-related toxicities for men with prostate cancer (PC). However, the feasibility of delivering exercise training to men with advanced disease and the wider impact on clinical outcomes remain unknown. The purpose of the EXACT trial was to determine the feasibility and effects of home-based exercise training in men with metastatic castrate-resistant prostate cancer (mCRPC).

METHODS

Patients with mCRPC receiving ADT + an androgen receptor pathway inhibitor (ARPI) were prescribed 12 weeks of home-based, remotely monitored, moderate intensity, aerobic and resistance exercise. Feasibility was assessed using recruitment, retention and adherence rates. Safety and adverse events were monitored throughout, with functional and patient-reported outcomes captured at baseline, post-intervention and at 3-month follow-up.

RESULTS

From the 117 screened, 49 were deemed eligible and approached, with 30 patients providing informed consent (61% recruitment rate). Of those who consented, 28 patients completed baseline assessments, with 24 patients completing the intervention and 22 completing follow-up (retention rates: 86% and 79% respectively). Task completion was excellent throughout, with no intervention-related adverse events recorded. Self-reported adherence to the overall intervention was 82%. Exercise training decreased mean body mass (-1.5%), improved functional fitness (> 10%) and improved several patient-reported outcomes including clinically meaningful changes in fatigue (p = 0.042), FACT-G (p = 0.054) and FACT-P (p = 0.083), all with moderate effect sizes.

CONCLUSION

Home-based exercise training, with weekly remote monitoring, was feasible and safe for men with mCRPC being treated with an ARPI. Given that treatment-related toxicities accumulate throughout the course of treatment, and as a result, negatively impact functional fitness and health-related quality of life (HRQoL), it was positive that exercise training improved or prevented a decline in these clinically important variables and could better equip patients for future treatment. Collectively, these preliminary feasibility findings support the need for a definitive, larger RCT, which downstream may lead to the inclusion of home-based exercise training as part of adjuvant care for mCRPC.
