Physical activity in the management of cancer-related fatigue induced by oncological treatments

Life style and interaction with microbiota in prostate cancer patients undergoing radiotherapy: study protocol for a randomized controlled trial

Background

Prostate cancer (PCa) is the second most common cancer in men worldwide. The standard non-surgical approach for localized PCa is radiotherapy (RT), but one of the limitations of high-dose RT is the potential increase in gastrointestinal and genitourinary toxicities. We present the protocol of the Microstyle study, a multicentre randomized two-arm crossover clinical trial. The primary outcome will be assessed at the end of 6-month intervention, by measuring the change in adherence to a healthy lifestyle score. The hypothesis is that modifying lifestyle we change microbiome and improve quality of life and decrease side effects of RT.

Methods

Study participants will be recruited among men undergoing RT in two Italian centers (Milan and Naples). We foresee to randomize 300 patients in two intervention arms: Intervention Group (IG) and Control Group (CG). Participants allocated to the IG will meet a dietitian and a physiotherapist before RT to receive personalized diet and exercise recommendations, according to their health status, to improve overall lifestyle and reduce side effects (bowel and/or urinary problems). Dietitian and physiotherapist will work together to set individualized goals to reduce or eliminate side effects and pain according to their health status. All participants (IG) will be given a pedometer device (steps counter) in order to monitor and to spur participants to increase physical activity and reduce sedentary behavior. Participants included in the CG will receive baseline general advice and materials available for patients undergoing RT. According to the cross-over design, the CG will cross to the intervention approach after 6-month, to actively enhance compliance towards suggested lifestyle recommendations for all patients.

Discussion

This trial is innovative in its design because we propose a lifestyle intervention during RT, that includes both dietary and physical activity counselling, as well as monitoring changes in microbiome and serum biomarkers. The promotion of healthy behaviour will be initiated before initiation of standard care, to achieve long lasting effects, controlling side effects, coping with feelings of anxiety and depression and improve efficacy of RT.

Effects of Supervised Multimodal Exercise Interventions on Cancer-Related Fatigue: Systematic Review and Meta-Analysis of Randomized Controlled Trials

OBJECTIVE

Cancer-related fatigue (CRF) is the most common and devastating problem in cancer patients even after successful treatment. This study aimed to determine the effects of supervised multimodal exercise interventions on cancer-related fatigue through a systematic review and meta-analysis.

DESIGN

A systematic review was conducted to determine the effectiveness of multimodal exercise interventions on CRF. Databases of PubMed, CENTRAL, EMBASE, and OVID were searched between January and March 2014 to retrieve randomized controlled trials. Risk of bias was evaluated using the PEDro scale.

RESULTS

Nine studies (n = 772) were included in both systematic review and meta-analysis. Multimodal interventions including aerobic exercise, resistance training, and stretching improved CRF symptoms (SMD = -0.23; 95% CI: -0.37 to -0.09; P = 0.001). These effects were also significant in patients undergoing chemotherapy (P < 0.0001). Nonsignificant differences were found for resistance training interventions (P = 0.30). Slight evidence of publication bias was observed (P = 0.04). The studies had a low risk of bias (PEDro scale mean score of 6.4 (standard deviation (SD) ± 1.0)).

CONCLUSION

Supervised multimodal exercise interventions including aerobic, resistance, and stretching exercises are effective in controlling CRF. These findings suggest that these exercise protocols should be included as a crucial part of the rehabilitation programs for cancer survivors and patients during anticancer treatments.

Quality of life and physical performance and activity of breast cancer patients after adjuvant treatments

OBJECTIVE

The study aimed at investigating the quality of life (QoL) and physical performance and activity, and their interrelations, in Finnish female breast cancer patients shortly after adjuvant treatments.

METHODS

A total of 537 disease-free breast cancer survivors aged 35-68 years were surveyed at the beginning of a one year randomized exercise intervention. The patients were interviewed using EORTC QLQ-C30, FACIT-F, RBDI, and WHQ (for vasomotor symptoms) questionnaires. Physical performance was tested by a 2 km walking test. Physical activity was measured by a questionnaire and a prospective two-week diary. Multivariate analysis was used to study the factors associated with QoL.

RESULTS

About 26% of the patients were rated as depressed, 20.4% as fatigued, and 82% suffered from menopausal symptoms. The global QoL was lower than in general population (69.4 vs 74.7, p<0.001). About 62% of the walking test results were below the population average. Fatigue (p<0.001), depression (p<0.001), body mass index (p = 0.016) and comorbidity (p = 0.032) impaired, and physical activity (p = 0.003) improved QoL. Physical activity level correlated positively to physical performance (r = -0.274, p<0.0001).

CONCLUSIONS

The QoL of the patients shortly after adjuvant treatments was impaired and the physical performance poor as compared to general population. In particular, depression and fatigue were related to impaired QoL. Physical performance and activity level were the only factors that correlated positively to QoL. Thus, physical exercise could be useful in rehabilitation of cancer survivors, especially for depressed and fatigued patients.

A multidimensional examination of correlates of fatigue during radiotherapy

BACKGROUND

Cancer-related fatigue can be measured as both a unidimensional and a multidimensional construct. Unidimensional fatigue and its symptom correlates have undergone some previous investigation; however, minimal research has considered the differential effect of correlates on individual dimensions of fatigue. The objective of the current study was to investigate cancer-related fatigue in a radiotherapy sample using a multidimensional conceptualization to determine whether correlates of fatigue are consistent across all dimensions or whether each fatigue dimension has its own unique pattern of correlates.

METHODS

The study used a prospective cohort design with data collected from radiotherapy patients at 3 time points; before, after, and 6 weeks after radiotherapy treatment.

RESULTS

A total of 210 participants were enrolled in the study. Results indicated the following relations. Increased general fatigue was found to be associated with lower performance status, being in a de facto relationship, depression, having treatment to the brain, and reduced vigorous physical activity. Increased physical fatigue was associated with lower performance status, depression, reduced physical activity, reduced productive hours, and nausea. Higher levels of reduced activity were associated with depression, decreased participation in activities of daily living, decreased number of productive hours, and lower performance status. Higher levels of reduced motivation were associated with radiotherapy to the brain, reduced moderate physical activity, and depression. Increased mental fatigue was associated with diagnosis of a brain tumor, anxiety, depression, and sleep problems.

CONCLUSIONS

The results of the current study support the recognition of multiple dimensions of fatigue, because each dimension examined had various correlates. These findings further develop our understanding of fatigue and may help clinicians provide more targeted information to people with cancer-related fatigue. Furthermore, these results can guide the development of group or individually tailored interventions that ultimately may reduce the impact of this distressing symptom on people with cancer.

Oncology and physical medicine and rehabilitation

INTRODUCTION

Cancer patients are living longer with deficiencies and functional impairments requiring often typically a care in physical medicine and rehabilitation (PMR).

OBJECTIVE

To examine the care of cancer patients in PMR.

METHOD

Investigation made with a questionnaire diffused from the e-mail listing of the Société Française de Médecine Physique et de Réadaptation.

RESULTS

Sixty-seven answers received. Fifty-seven centers take care of cancer patients. On average, 4% of cancer patients are hospitalised in PMR. Spinal cord injuries and hemiplegias are the most common impairments. Forty-two percent of the PMR units take the patients in all the stages of cancer treatment. Working relationships between PMR and oncology units are formalized only eight times out of 52. In case of health degradation, relationships with a palliative care unit are frequent but not generalized. Eighty-five percent of the centers think that PMR is not enough developed in oncology.

CONCLUSIONS

In spite of its limited character, this investigation shows that the PMR units take these patients. Situations where PMR has an important role in the follow-up of cancer patients are multiple and publications have showed its interest, especially on the limitations of activities. It is important to make better known the interest of PMR in oncology units but also to develop specific care within PMR units.

Cancer-Related Fatigue: A Review and a Conceptual Framework to Guide Therapists' Understanding

Cancer-related fatigue is reported as the most common and distressing symptom experienced by people with cancer. There is limited research published to guide occupational therapists working with people with cancer to help address this distressing symptom. This article reviews literature on cancer-related fatigue and identifies several factors associated with the development of fatigue, including underlying medical factors and other factors.

The underlying medical factors reported in the literature include biomedical mechanisms, such as anaemia, proinflammatory cytokines and specific cellular processes; disease-related factors; treatment-related factors; and comorbid conditions. Other factors reviewed include physical or behavioural factors, such as poor nutrition, decreased activity, sleep disturbance and pain; psychological factors, including anxiety and depression; and sociodemographic factors, such as social support, employment and education.

The review identified a variety of factors associated with cancer-related fatigue, which must be considered by occupational therapists working with people with cancer. This presents a challenge to the clinical reasoning of occupational therapists attempting to treat such people. A framework of factors contributing to cancer-related fatigue is proposed in order to guide both the practice of occupational therapists working with adults with cancer and future research in this area.
