Differential effects of exercise on cancer-related fatigue during and following treatment: a meta-analysis

Medical and neurologic management of brain tumor patients

PURPOSE OF REVIEW

This article discusses commonly encountered medical and neurological complications in patients with brain tumors and highlights recommendations for their management based on updated evidence.

RECENT FINDINGS

Use of dexamethasone is correlated with worse prognosis in patients with glioblastoma, and in brain metastases, high doses may lead to increased side effects without additional clinical benefit. There are multiple antiseizure medications (ASM) to choose from and possible interactions and toxicity must be considered when choosing an agent. Additionally, there is growing interest in the use of AMPA receptor blockers as ASM in patients with brain tumors. Nonpharmacological strategies for the management of fatigue remain paramount. Cognitive decline is common after whole brain radiation (WBRT) and hippocampal-sparing WBRT results in superior cognitive outcomes. Venous thromboembolism is a common complication and there is growing evidence on the use of direct oral anticoagulants (DOACs) in this population.

SUMMARY

There is evolving evidence on the management of medical and neurological complications in patients with brain tumors. These complications, require early identification and multidisciplinary collaboration and expertise.

Protective effects of exercise on cardiotoxicity induced by breast cancer treatments: A systematic review and meta-analysis

OBJECTIVE

Currently, one of the main causes of death in women with breast cancer is cardiovascular disease caused by the oncologic therapies. Exercise has demonstrated positive effects on cardiovascular fitness in individuals without cancer. Therefore, the aim of this study was to evaluate the cardioprotective effects of exercise in women with breast cancer, during and after the application of their treatments.

METHODS

Systematic search was done in PubMed, Scopus, Web of Science, CINAHL, MEDLINE, SPORTDiscus, and PEDro. The articles must have been published in the last ten years; the intervention to be evaluated was to consist of an exercise program; the sample had to comprise women who were undergoing breast cancer treatment or who had completed it at the time of the intervention; and the outcome variables had to include at least one parameter for the assessment of cardiac function and/or structure.

RESULTS

Of the 28 articles identified, nine reported non-randomized controlled studies, 16 randomized clinical trials and three quasi-experimental studies. The effects of exercise on left ventricular ejection fraction, global longitudinal strain and the E/A waveforms ratio were not significant. However, its effect on VO2max was significant.

CONCLUSIONS

Exercise does not seem to be effective in avoiding the cardiotoxic effects of oncological treatment for breast cancer. Although exercise seems to mitigate the symptomatology, reflected in improved functional capacity, more long-term studies are needed.

Harnessing the Systemic Biology of Functional Decline and Cachexia to Inform more Holistic Therapies for Incurable Cancers

Options for treatment of incurable cancer remain scarce and are largely focused on limited therapeutic mechanisms. A new approach specific to advanced cancers is needed to identify new and effective treatments. Morbidity in advanced cancer is driven by functional decline and a number of systemic conditions, including cachexia and fatigue. This review will focus on these clinical concepts, describe our current understanding of their underlying biology, and then propose how future therapeutic strategies, including pharmaceuticals, exercise, and rehabilitation, could target these mechanisms as an alternative route to addressing incurable cancer.

An eHealth App (CAPABLE) Providing Symptom Monitoring, Well-Being Interventions, and Educational Material for Patients With Melanoma Treated With Immune Checkpoint Inhibitors: Protocol for an Exploratory Intervention Trial

BACKGROUND

Since treatment with immune checkpoint inhibitors (ICIs) is becoming standard therapy for patients with high-risk and advanced melanoma, an increasing number of patients experience treatment-related adverse events such as fatigue. Until now, studies have demonstrated the benefits of using eHealth tools to provide either symptom monitoring or interventions to reduce treatment-related symptoms such as fatigue. However, an eHealth tool that facilitates the combination of both symptom monitoring and symptom management in patients with melanoma treated with ICIs is still needed.

OBJECTIVE

In this pilot study, we will explore the use of the CAPABLE (Cancer Patients Better Life Experience) app in providing symptom monitoring, education, and well-being interventions on health-related quality of life (HRQoL) outcomes such as fatigue and physical functioning, as well as patients' acceptance and usability of using CAPABLE.

METHODS

This prospective, exploratory pilot study will examine changes in fatigue over time in 36 patients with stage III or IV melanoma during treatment with ICI using CAPABLE (a smartphone app and multisensory smartwatch). This cohort will be compared to a prospectively collected cohort of patients with melanoma treated with standard ICI therapy. CAPABLE will be used for a minimum of 3 and a maximum of 6 months. The primary endpoint in this study is the change in fatigue between baseline and 3 and 6 months after the start of treatment. Secondary end points include HRQoL outcomes, usability, and feasibility parameters.

RESULTS

Study inclusion started in April 2023 and is currently ongoing.

CONCLUSIONS

This pilot study will explore the effect, usability, and feasibility of CAPABLE in patients with melanoma during treatment with ICI. Adding the CAPABLE system to active treatment is hypothesized to decrease fatigue in patients with high-risk and advanced melanoma during treatment with ICIs compared to a control group receiving standard care. The Medical Ethics Committee NedMec (Amsterdam, The Netherlands) granted ethical approval for this study (reference number 22-981/NL81970.000.22).

Effect of Exergaming on Quality of Life, Fatigue, and Strength and Endurance Muscle in Cancer Patients: A Randomized Crossover Trial

Objective: To analyze the influence of exergaming (EXE) quality of life, cancer-related fatigue (CRF), electromyography, and strength and endurance muscle in a randomized crossover trial. Methods: We conducted a single-blinded, randomized, and crossover trial, which included 38 cancer volunteers undergoing chemotherapy (Age = 60.07 ± 12.10 years; body mass index = 26.79 ± 5.33 kg/m2). All volunteers were randomized into two intervention moments: EXE and without intervention (WI) and after 1-month washout period of crossing of the evaluated moments. The intervention was performed on an EXE protocol using Xbox 360 Kinect®, with the game "Your Shape Fitness Evolved 2012" two to three times per week for 20 sessions. All volunteers were assessed the CRF and quality-of-life levels through the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire, the median frequency (MDF) by surface electromyography, maximal voluntary isometric contraction (MVIC), and the muscle endurance time at 80% MVIC of the dorsiflexors and plantar flexors using dynamometer. Results: In the comparison between EXE and WI moments, were observed increase in the scores for quality of life (P < 0.001), subscale fatigue (P < 0.001), in the MDF values of right lateral gastrocnemius muscles: P = 0.017, muscle endurance time (left dorsiflexion [LDF]: P < 0.001; right dorsiflexion [RDF]: P < 0.001; left plantar flexion [LPF]: P < 0.001; RPF: P = 0.039), and muscle strength (LDF: P < 0.001; RDF: P < 0.001; LPF: P = 0.002). Conclusion: The crossover study, the EXE protocol promoted improvement in cancer-related fatigue (CRF) and quality of life, increased MVIC, endurance time, and MDF values of the dorsiflexor and plantar flexor muscles of cancer volunteers undergoing chemotherapy.

The association of cancer-related fatigue on the social, vocational and healthcare-related dimensions of cancer survivorship

BACKGROUND

Cancer-related fatigue (CRF) is well documented in cancer survivors, but little is known about the personal and societal impact of CRF. This study aimed to examine the impact of CRF in relation to social and vocational functioning and health care utilization in a large sample of post-treatment cancer survivors.

METHODS

We conducted a cross-sectional descriptive study of early stage breast and colorectal cancer survivors (n = 454) who were within 5 years from treatment completion. Social difficulties (SDI-21), work status, absenteeism and presenteeism (WHO-HPQ) and healthcare utilization (HSUQ) were compared in those with (CFR +) and without (CRF -) clinically significant fatigue (FACT-F ≤ 34).

RESULTS

A total of 32% met the cut-off criteria for CRF (≤ 34). Participants with CRF + had significantly higher scores on the SDI-21 across all domains and 55% of CRF + vs. 11% in CRF - was above the SDI cut-off (> 10) for significant social difficulties. Participants with CRF + were 2.74 times more likely to be unemployed or on leave (95% CI 1.62, 4.61, p < 0.001). In the subgroup of participants who were currently working (n = 249), those with CRF + reported working on average 27.4 fewer hours in the previous 4 weeks compared to CRF - (p = 0.05), and absolute presenteeism was on average 13% lower in the CRF + group (95% CI 8.0, 18.2, p < 0.001). Finally, individuals with CRF + reported significantly more physician (p < 0.001), other health care professional (p = 0.03) and psychosocial visits (p = 0.002) in the past month.

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

CRF is associated with substantial disruption in social and work role functioning in the early transitional phase of cancer survivorship. Better management of persistent CRF and funding for the implementation of existing guidelines and recommended evidence-based interventions are urgently needed.

The effects of a physical exercise program in Chinese kidney transplant recipients: a prospective randomised controlled trial

Background

Kidney transplant has become the preferred therapy for end-stage renal disease. However, kidney transplant recipients (KTRs) still face several challenges, such as physical inactivity. The purpose of this study was to explore the effects of a nurse-led physical exercise program in Chinese KTRs.

Methods

A total of 106 participants were enrolled from the Third Xiangya Hospital of Central South University between July 2021 and June 2022 and randomly assigned to the control or intervention groups. Participants in the control group were provided with routine nursing care and participants in the intervention group received a nurse-led rigorous physical exercise program that was divided into two stages: the pre-discharge stage and the post-discharge stage. The pre-discharge stage included the non-ambulatory and ambulatory stages. The Chinese traditional exercise Baduanjin was incorporated into the physical exercise during the ambulatory stage. The post-discharge stage continued the same exercise as the ambulatory stage at home. After 3 months of intervention, both groups received the same follow-up for 3 months. The primary and secondary outcomes of all participants were collected. The data were analysed with repeated measures analysis of variance to examine the effectiveness of the intervention.

Results

Compared with the control group, the intervention group had less fatigue and more motivation to be active in primary outcomes. Moreover, patients in the intervention group had a higher phase angle, a longer 6-minute walk distance, more 30-second chair stand times and decreased anxiety and depression levels in secondary outcomes. No adverse events were observed during the intervention. There were no significant differences in all dimensions of the quality-of-life questionnaire between the intervention and the control group.

Conclusion

Chinese KTRs could benefit from the nurse-led physical exercise program post-operatively.

Changes in the quality of life of early breast cancer patients and comparison with the normative Slovenian population

BACKGROUND

We aimed to identify changes in quality of life after breast cancer treatment and compare them with the normative population data for the Slovenian population.

PATIENTS AND METHODS

A prospective, single-group, cohort design was used. A total of 102 early breast cancer patients treated with chemotherapy at the Institute of Oncology Ljubljana were included. Of those, 71% returned the questionnaires after one-year post-chemotherapy. The Slovenian versions of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ C30 and BR23 questionnaires were used. Primary outcomes were a comparison of global health status/quality of life (GHS) and C30 Summary Score (C30-SumSc) at baseline and one-year post-chemotherapy with the normative Slovenian population. The exploratory analysis evaluated the differences in symptoms and functional scales of QLQ C-30 and QLQ BR-23 between baseline and one-year post-chemotherapy.

RESULTS

At baseline and one-year post-chemotherapy, C30-SumSc of patients was lower than the predicted C30-SumSc from the normative Slovenian population by 2.6 points (p = 0.04) and 6.5 points (p < 0.001), resp. On the contrary, GHS was not statistically different from predicted either at baseline or after one year. Exploratory analysis revealed that one-year post-chemotherapy compared to the beginning of chemotherapy, patients had statistically significantly and clinically meaningful lower scores in body image and cognitive functioning, and increased symptom scores for pain, fatigue, and arm symptoms.

CONCLUSIONS

The C30-SumSc is reduced one-year post-chemotherapy. Early interventions should be directed toward the prevention of the decline of cognitive functioning and body image, and to alleviate fatigue, pain, and arm symptoms.

The effects of physical exercise in the palliative care phase for people with advanced cancer: a systematic review with meta-analysis

PURPOSE

The purpose of this systematic review with meta-analysis was to evaluate the safety, feasibility and effectiveness of exercise in the palliative care phase for people with advanced cancer.

METHODS

Electronic databases were searched for exercise randomised controlled trials involving individuals with incurable cancer that were published prior to April 14, 2021. Meta-analyses were performed to evaluate the effects of exercise on health outcomes. Subgroup effects for exercise mode, supervision, intervention duration and cancer diagnosis were assessed.

RESULTS

Twenty-two trials involving interventions ranging between 2 weeks and 6 months were included. Interventions comprised of aerobic (n = 3), resistance (n = 4), mixed-mode (n = 14) and other exercise (n = 1) modalities. Cancer types consisted of lung (n = 6), breast (n = 3), prostate (n = 2), multiple myeloma (n = 1) and mixed cancer types (n = 10). Meta-analysis of 20 RCTs involving 1840 participants showed no difference in the risk of a grade 2-4 adverse event between exercise and usual care (n = 110 adverse events (exercise: n = 66 events; usual care: n = 44 events), RD =  - 0.01 (91% CI =  - 0.01, 0.02); p = 0.24). Overall median recruitment, retention and adherence rates were 56%, 80% and 69%, respectively. Meta-analysis of health outcomes showed effects in favour of exercise for quality of life, fatigue, aerobic fitness and lower-body strength (SMD range = 0.27-0.48, all p < 0.05).

CONCLUSIONS

Participants who engaged in exercise experienced an increase in quality of life, fitness and strength and a decrease in fatigue.

IMPLICATIONS FOR CANCER SURVIVORS

Physical activity programs were found to be safe and feasible for people with advanced cancer in the palliative care phase.

Effectiveness of exercise interventions in the management of cancer-related fatigue: a systematic review of systematic reviews

BACKGROUND

Cancer-related fatigue is a widely prevalent global public health concern with serious consequences. Increasing evidence suggests the effectiveness of exercise intervention in treating cancer-related fatigue, but there is a lack of a summary of relevant literature on the same to help reach a clear consensus.

OBJECTIVE

To summarize evidence regarding the efficacy of exercise interventions to reduce cancer fatigue, as determined in systematic reviews (SRs) and/or meta-analyses (MAs).

METHOD

From inception to September 2022, PubMed (1948-2022), Embase (1974-2022), Cochrane Library (1993-2022), CINAHL (1937-2022), Web of Science (1997-2022), China Knowledge Resource Integrated Database (1999-2022), Wanfang Database (1993-2022), and Chinese Biomedical Database (1994-2022) were searched for inclusion to the study. Two reviewers independently extracted the data from the included articles. AMSTAR II was to evaluate the methodological quality of the reviews.

RESULTS

A total of 46 systematic reviews were assessed for data on exercise intervention in reducing cancer-related fatigue among cancer patients. In addition, some studies have reported adverse events during the exercise intervention period. The quality of the included systematic review was found to be low or critically low.

CONCLUSIONS

The present systematic review of systematic reviews supports exercise intervention for reducing cancer-related fatigue. Further higher-quality studies are warranted to improve the level of evidence for exercise interventions for application in the treatment of cancer-related fatigue.

Does inflammation markers or treatment type moderate exercise intensity effects on changes in muscle strength in cancer survivors participating in a 6-month combined resistance- and endurance exercise program? Results from the Phys-Can trial

BACKGROUND

Resistance exercise has a beneficial impact on physical function for patients receiving oncological treatment. However, there is an inter-individual variation in the response to exercise and the tolerability to high-intensity exercise. Identifying potential moderating factors, such as inflammation and treatment type, for changes in muscle strength is important to improve the effectiveness of exercise programs. Therefore, we aimed to investigate if inflammation and type of oncological treatment moderate the effects of exercise intensity (high vs. low-moderate) on muscular strength changes in patients with breast (BRCA) or prostate cancer (PRCA).

METHODS

Participants with BRCA (n = 286) and PRCA (n = 65) from the Physical training and Cancer study (Phys-Can) were included in the present study. Participants performed a combined resistance- and endurance exercise program during six months, at either high or low-moderate intensity. Separate regression models were estimated for each cancer type, with and without interaction terms. Moderators included in the models were treatment type (i.e., neo/adjuvant chemotherapy-yes/no for BRCA, adjuvant androgen deprivation therapy (ADT)-yes/no for PRCA)), and inflammation (interleukin 6 (IL6) and tumor necrosis factor-alpha (TNFα)) at follow-up.

RESULTS

For BRCA, neither IL6 (b = 2.469, 95% CI [- 7.614, 12.552]) nor TNFα (b = 0.036, 95% CI [- 6.345, 6.418]) levels moderated the effect of exercise intensity on muscle strength change. The same was observed for chemotherapy treatment (b = 4.893, 95% CI [- 2.938, 12.724]). Similarly, for PRCA, the effect of exercise intensity on muscle strength change was not moderated by IL6 (b = - 1.423, 95% CI [- 17.894, 15.048]) and TNFα (b = - 1.905, 95% CI [- 8.542, 4.732]) levels, nor by ADT (b = - 0.180, 95% CI [- 11.201, 10.841]).

CONCLUSIONS

The effect of exercise intensity on muscle strength is not moderated by TNFα, IL6, neo/adjuvant chemotherapy, or ADT, and therefore cannot explain any intra-variation of training response regarding exercise intensity (e.g., strength gain) for BRCA or PRCA in this setting.

Management of cancer-related fatigue in Taiwan: an evidence-based consensus for screening, assessment and treatment

BACKGROUND

Cancer-related fatigue is one of the most common and persistent issues experienced by cancer patients. Cancer-related fatigue is a distinct form of fatigue that is subjective, long-lasting and unalleviated by rest or sleep. Studies have shown that almost all cancer patients experience severe fatigue that disrupts the quality of life and physical function, but cancer-related fatigue remains under-addressed in clinical care, and only about half of all patients receive treatment.

METHODS

To increase the awareness of cancer-related fatigue and improve current management, the Taiwan Society of Cancer Palliative Medicine and the Taiwan Oncology Nursing Society convened a consensus committee to develop recommendations for the screening, assessment and treatment of cancer-related fatigue.

RESULTS

Thirteen consensus recommendations were subsequently developed based on the best available evidence and the clinical experience of committee members.

CONCLUSIONS

These recommendations are expected to facilitate the standardization of cancer-related fatigue management across Taiwan and may also serve as a reference for other clinicians.

Long Term Effects of a Social Capital-Based Exercise Adherence Intervention for Breast Cancer Survivors With Moderate Fatigue: A Randomized Controlled Trial

OBJECTIVES

This study reports on the long-term effects of the Better Life After Cancer: Energy, Strength, and Support (BLESS) program, a 12-week social capital-based exercise adherence program for breast cancer survivors (BCS), implemented using a randomized controlled trial design. The study investigated outcomes related to cancer-related fatigue (CRF), quality of life (QOL), physical activity, depression, anxiety, sleep quality, and social capital.

METHODS

Participants who had moderate or greater CRF were randomly assigned to the intervention (n = 24), consisting of supervised and home-based exercise, or the control (n = 26), who received exercise leaflets. Generalized estimating equations models were fitted for the outcome variables. The assessment points were baseline (M1), immediately after completing the intervention at 12 weeks (M2), 1 month (M3), and 6 months post-intervention (M4).

RESULTS

A significant reduction in the total CRF score was found for both groups. We observed a significant time by group effect at M2, indicating a reduction of behavioral/severity CRF scores and a higher increase of physical activity. Also, there was an increase in the QOL score of both groups at M2, M3, and M4, compared to M1. Both groups had reduced anxiety at M3 and M4 compared to M1. The time by group effect for depression, sleep quality and social capital was not statistically significant.

CONCLUSION

This 12-week exercise adherence program improved behavioral/severity CRF and physical activity post-intervention. Both the experimental group and control group showed significant improvements in CRF, QOL, and anxiety domains compared to the baseline, which extended to 6 months post-intervention.

A Survey-Based Study on Physical Activity Promotion for Individuals with a Current or Past Diagnosis of Cancer in Canada

PURPOSE

To determine the prevalence and content of discussions regarding physical activity (PA) promotion between individuals with a current or past diagnosis of cancer and their oncology care team.

METHODS

Design and Procedure: A cross-sectional survey on PA discussion between individuals with a current or past diagnosis of cancer and their oncology care team was conducted at a single timepoint.

PARTICIPANTS

Eligible participants were adults with a current or past diagnosis of cancer at any time point in their cancer treatment who had a pre-scheduled appointment with their oncology care team.

RESULTS

A total of 100 participants completed the survey. PA-related discussions happened in 41% of the patient-provider interactions and 66% of respondents reported PA discussions at some point during care. No significant association occurred between cancer type, stage, or treatment status and PA discussions at any timepoint (all p's > 0.05). Most respondents were satisfied with the education provided on PA (54%); however, only 37% were sufficiently active. Those receiving education from their medical oncologist were more likely to be 'sufficiently active' (p = 0.020) according to the Godin Leisure Time Exercise Questionnaire.

CONCLUSIONS

Most respondents discuss PA with an oncology care provider at some point during their cancer treatment; however, few are sufficiently active. Future research is needed to determine strategies to facilitate PA promotion and close the gap between discussions and actual physical activity behavior.

Impact of radiation therapy on fatigue at 1 year in breast cancer survivors in the prospective multicentre CANcer TOxicity cohort

BACKGROUND

Fatigue is a common and disabling symptom after breast cancer (BC) treatment, significantly impacting patients' quality of life. We aimed to assess the impact of radiation therapy (RT) modalities on fatigue one year after treatment among patients with early-stage BC.

METHODS

We used CANTO-RT, a subcohort of CANcer TOxicity (CANTO; NCT01993498), a multicentric nationwide prospective cohort of stages I-III BC treated from 2012 to 2017. Our primary outcome was severe global fatigue 1 year after RT completion (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 score ≥40/100). The secondary outcomes included severe physical, emotional and cognitive fatigue (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-FA12). RT-related variables were used as independent variables. Multivariable logistic regression models assessed associations between RT-related variables and fatigue.

RESULTS

The final analytic cohort included 3295 patients. The prevalence of severe global fatigue 1 year after treatment was 33.3%. Internal mammary chain RT (adjusted odds ratio [OR] 1.48 [95% confidence interval [CI] 1.03-2.13; p = 0.0355]) and normofractionated RT (adjusted OR 1.88 [95% CI 1.06-3.31; p = 0.0298]) were associated with increased odds of severe global fatigue. In addition, there was a significant association between normofractionated RT (adjusted OR 1.849 [95% CI 1.04-3.3; p = 0.0354]) and an increased likelihood of severe physical fatigue.

CONCLUSION

We found a significant association between internal mammary chain RT (versus No), normofractionated RT (versus hypofractionated RT) and increased likelihood of persistent severe global fatigue. Our data add to the current understanding of treatment-related factors affecting fatigue after BC and could lead to personalised interventions to improve the prevention and management of this disabling symptom.

Does aquatic physical therapy affect the rehabilitation of breast cancer in women? A systematic review and meta-analysis of randomized controlled trials

To determine and evaluate the benefits of aquatic physical therapy as a rehabilitation strategy for women with breast cancer on health outcomes. Electronic databases including PubMed, Web of Science, Embase, Cochrane Library and China National Knowledge Infrastructure (CNKI), Weipu (VIP) and Wanfang database were systematically searched until June 2021. Randomized controlled trials were included if they evaluated the effects of aquatic physical therapy in breast cancer patients. The quality of the trials included was assessed by the two independent researchers according to the Cochrane Collaboration Handbook recommendations. Outcome measures were fatigue, waist circumference and quality of life (QoL). The study was registered under PROSPERO (CRD42021157323). Totally, five studies comprising 356 participants were included in the study. Meta-analyses showed that aquatic physical therapy interventions significantly reduced the fatigue score (MD = -2.14, 95%CI: -2.82, -1.45, p<0.01) compared with usual care; In addition, we also observed that, compared with land-based exercise, aquatic physical therapy greatly improved the QoL (MD = 2.85, 95%CI: 0.62, 5.09, p = 0.01). However, aquatic physical therapy cannot improve physical index (waist circumference) compared to usual care (MD = -3.49, 95%CI: -11.56,4.58, p = 0.4). Consequently, aquatic physical therapy had a positive effect on the fatigue and QoL. The results of this meta-analysis can provide a reliable evidence for evaluating the interventional effectiveness of aquatic physical therapy.

The mediating effect of social functioning on the relationship between social support and fatigue in middle-aged and young recipients with liver transplant in China

Objective

The objective of the study was to explore the relationship between social support and fatigue as well as the mediating role of social functioning on that relationship.

Background

Psychosocial factors such as social support and social functioning may influence patients’ fatigue symptoms. There is limited evidence on the relationship between social support, social functioning, and fatigue in liver transplant recipients.

Methods

A total of 210 patients with liver transplants from two tertiary hospitals were enrolled in the current study. Questionnaires used include one for general demographic data, the Perceived Social Support Scale (PSSS), Social Disability Screening Schedule (SDSS), and Fatigue Symptom Inventory (FSI).

Results

A total of 126 (60%) recipients reported fatigue. Gender, residence, BMI, and liver function were the primary factors affecting fatigue. Social support was positively correlated with social functioning and was negatively correlated with fatigue. The effect of social support on fatigue was partially mediated by social functioning (35.74%).

Conclusion

The fatigue of liver transplant recipients should be attended to. The higher the social support, the lower the fatigue of liver transplant recipients. Social support may also reduce fatigue through social functioning. The liver transplant team should help the liver transplant recipient establish a social support system, restore social functioning, and reduce fatigue symptoms.

Effects of Acceptance and Commitment Therapy on fatigue interference and health-related quality of life among patients with advanced lung cancer: A pilot randomized controlled trial

Objective

The present study aimed to examine the feasibility and preliminary effects of Acceptance and Commitment Therapy (ACT) on fatigue interference and health-related quality of life in patients with advanced lung cancer.

Methods

In a single-blinded, parallel-group randomized controlled trial, 40 patients with advanced lung cancer were randomized to either the intervention group, which received the four-session individual ACT in 4 weeks, or the control group, which received usual care. The outcomes were evaluated at baseline and one week postintervention.

Results

Intervention feasibility and acceptability were established with a high attendance rate of 88.75% and a high retention rate of 75%. Approximately 95% of the participants reported satisfaction with the intervention. Despite the insignificant effects on fatigue interference, statistically significant interactions effects of ACT for health-related quality of life (P ​= ​0.001), cancer-related fatigue (P ​< ​0.001), depressive symptoms (P ​< ​0.001), anxiety (P ​< ​0.001), and distress (P ​= ​0.003) were noted.

Conclusions

This pilot trial supports the feasibility and acceptability of conducting ACT for patients with advanced lung cancer. The findings show the potential positive effects of ACT on health-related quality of life. Future studies with full-scale samples are recommended to evaluate the long-term effects of ACT on fatigue interference.

The Effect of Chronic Exercise on Energy and Fatigue States: A Systematic Review and Meta-Analysis of Randomized Trials

In this meta-analysis, we synthesized the results of randomized controlled trials of different exercise training interventions on participants' feelings of fatigue, energy, and vitality. The search of studies was conducted using six databases as well as several other supplementary search strategies available before December 2021. The initial search generated over 3,600 articles with 81 studies (7,050 participants) and 172 effects meeting the inclusion criteria. We analyzed the effects from the studies using a meta-analytic multivariate model and considered the potential moderating effect of multiple variables. Our analysis revealed exercise to decrease the feelings of fatigue by a small effect size (g = -0.374; 95% CI [-0.521, -0.227]), increase energy by a small-to-moderate effect size (g = 0.415; 95% CI [0.252, 0.578]), and to increase the feeling of vitality by a moderate effect size (g = 0.537; 95% CI [0.404, 0.671]). All main results remained robust after several sensitivity analyses using different statistical estimators, and consideration of outlier and influential studies. Moreover, moderator analyses revealed significant effects of exercise intensity and intervention duration on fatigue, exercise intensity, and modality on energy, and participant health, exercise intensity modality, and exercise training location on vitality. We conclude that when groups adopt a moderate intensity exercise training program while participating in a randomized trial, compared to controls, this typically results in small-to-moderate average improvements in feelings of fatigue, energy, and vitality.

A phase III randomized trial of weight loss to reduce cancer-related fatigue among overweight and obese breast cancer patients: MEDEA Study design

Background

Elevated body mass index (BMI) represents a risk factor for cancer-related fatigue (CRF). Weight loss interventions are feasible and safe in cancer survivors, leading to improved cardio-metabolic and quality of life (QOL) outcomes and modulating inflammatory biomarkers. Randomized data are lacking showing that a lifestyle intervention aimed at weight loss, combining improved diet, exercise, and motivational counseling, reduces CRF. Motivating to Exercise and Diet, and Educating to healthy behaviors After breast cancer (MEDEA) is a multi-center, randomized controlled trial evaluating the impact of weight loss on CRF in overweight or obese survivors of breast cancer. Herein, we described the MEDEA methodology.

Methods

Patients (N = 220) with stage I–III breast cancer and BMI ≥ 25 kg/m², within 12 months of primary treatment, and able to walk ≥ 400 m are eligible to enroll. Participants are randomized 1:1 to health education alone vs. a personalized telephone-based weight loss intervention plus health education. Both arms receive a health education program focusing on healthy living. Patients in the intervention arm are paired with an individual lifestyle coach, who delivers the intervention through 24 semi-structured telephone calls over 1 year. Intervention goals include weight loss ≥ 10% of baseline, caloric restriction of 500–1000 Kcal/day, and increased physical activity (PA) to 150 (initial phase) and 225–300 min/week (maintenance phase). The intervention is based on the social cognitive theory and is adapted from the Breast Cancer Weight Loss trial (BWEL, A011401). The primary endpoint is the difference in self-reported CRF (EORTC QLQ-C30) between arms. Secondary endpoints include the following: QOL (EORTC QLQ-C30, -BR45, -FA12), anxiety, and depression (HADS); weight and BMI, dietary habits and quality, PA, and sleep; health care costs (hospital-admissions, all-drug consumption, sick leaves) and cost-effectiveness (cost per quality-adjusted life-year); and patient motivation and satisfaction. The primary analysis of MEDEA will compare self-reported CRF at 12 months post-randomization between arms, with 80.0% power (two-sided α = 0.05) to detect a standardized effect size of 0.40.

Discussion

MEDEA will test the impact of a weight loss intervention on CRF among overweight or obese BC survivors, potentially providing additional management strategies and contributing to establish weight loss support as a new standard of clinical care.

Utilizing a Team Kinesiology Model to Support Rehabilitative Care in Patients

An approach that provides a standardized way of continuing rehabilitative care to help patients return to their lives and activities of daily living (ADL) in an economical and efficient manner is the Team Kinesiology Model (TKM). Many patients who are given a life-altering diagnosis (i.e., paralysis due to spinal cord injury, cerebral palsy, or cancer) are unable to return to employment, their family or a pre-diagnosis quality of life (QOL) given the current health care resources. This is a longstanding, and urgent problem as population aging and rising multi-morbidity is projected to negatively impact all regions of the world. Utilization of mid-level rehabilitation services is a proposed method to increase accessibility to all populations, including those of lower socioeconomic status or minority populations. Capitalizing on this idea, we describe two different programs that use the TKM to provide rehabilitative services to patients who were diagnosed with nervous system dysfunction or cancer. This model benefits the patient by improving physical fitness, psychosocial function, and QOL. Furthermore, we provide specific examples that show how this approach could have further-reaching impacts on society, education and research. Integrating kinesiologists and TKM in health care could assist in workflow, long-term health surveillance, rehabilitation and improvement of QOL.

Uptake of Recommendations for Posttreatment Cancer-Related Fatigue Among Breast Cancer Survivors

BACKGROUND

Physical activity (PA) and psychosocial interventions are recommended management strategies for cancer-related fatigue (CRF). Randomized trials support the use of mind-body techniques, whereas no data show benefit for homeopathy or naturopathy.

METHODS

We used data from CANTO (ClinicalTrials.gov identifier: NCT01993498), a multicenter, prospective study of stage I-III breast cancer (BC). CRF, evaluated after primary treatment completion using the EORTC QLQ-C30 (global CRF) and QLQ-FA12 (physical, emotional, and cognitive dimensions), served as the independent variable (severe [score of ≥40/100] vs nonsevere). Outcomes of interest were adherence to PA recommendations (≥10 metabolic equivalent of task [MET] h/week [GPAQ-16]) and participation in consultations with a psychologist, psychiatrist, acupuncturist, or other complementary and alternative medicine (CAM) practitioner (homeopath and/or naturopath) after CRF assessment. Multivariable logistic regression examined associations between CRF and outcomes, adjusting for sociodemographic, psychologic, tumor, and treatment characteristics.

RESULTS

Among 7,902 women diagnosed from 2012 through 2017, 36.4% reported severe global CRF, and 35.8%, 22.6%, and 14.1% reported severe physical, emotional, and cognitive CRF, respectively. Patients reporting severe global CRF were less likely to adhere to PA recommendations (60.4% vs 66.7%; adjusted odds ratio [aOR], 0.82; 95% CI, 0.71-0.94; P=.004), and slightly more likely to see a psychologist (13.8% vs 7.5%; aOR, 1.29; 95% CI, 1.05-1.58; P=.014), psychiatrist (10.4% vs 5.0%; aOR, 1.39; 95% CI, 1.10-1.76; P=.0064), acupuncturist (9.8% vs 6.5%; aOR, 1.46; 95% CI, 1.17-1.82; P=.0008), or CAM practitioner (12.5% vs 8.2%; aOR, 1.49; 95% CI, 1.23-1.82; P<.0001). There were differences in recommendation uptake by CRF dimension, including that severe physical CRF was associated with lower adherence to PA (aOR, 0.74; 95% CI, 0.63-0.86; P=.0001) and severe emotional CRF was associated with higher likelihood of psychologic consultations (aOR, 1.37; 95% CI, 1.06-1.79; P=.017).

CONCLUSIONS

Uptake of recommendations to improve CRF, including adequate PA and use of psychosocial services, seemed suboptimal among patients with early-stage BC, whereas there was a nonnegligible interest in homeopathy and naturopathy. Findings of this large study indicate the need to implement recommendations for managing CRF in clinical practice.

Sexual Health Dysfunction After Radiotherapy for Gynecological Cancer: Role of Physical Rehabilitation Including Pelvic Floor Muscle Training

Introduction

The present study aims to describe: 1. How the side effects of radiotherapy (RT) could impact sexual health in women; 2. The effectiveness of physical rehabilitation including pelvic floor muscle training (PFMT) in the management of sexual dysfunction after RT.

Materials and Methods

Search keys on PubMed, Web of Science, Scopus, PEDro, and Cochrane were used to identify studies on women treated with radical or adjuvant RT and/or brachytherapy for gynecological cancers with an emphasis on vulvo-vaginal toxicities and PFMT studies on sexual dysfunction for this group of women.

Results

Regarding the first key question, we analyzed 19 studies including a total of 2,739 women who reported vaginal dryness, stenosis, and pain as the most common side effects. Reports of dosimetric risk factors and dose-effect data for vaginal and vulvar post-RT toxicities are scant. Only five studies, including three randomized controlled trials (RCTs), were found to report the effect of PFMT alone or in combination with other treatments. The results showed some evidence for the effect of training modalities including PFMT, but to date, there is insufficient evidence from high-quality studies to draw any conclusion of a possible effect.

Conclusions

Gynecological toxicities after RT are common, and their management is challenging. The few data available for a rehabilitative approach on post-actinic vulvo-vaginal side effects are encouraging. Large and well-designed RCTs with the long-term follow-up that investigate the effect of PFMT on vulvo-vaginal tissues and pelvic floor muscle function are needed to provide further guidance for clinical management.

Totally Excited about Moving Mobility and Exercise (TEAM Me): A Successful Multidisciplinary Exercise Quality Improvement Initiative for Pediatric and Young Adult Oncology and Stem Cell Transplant Inpatients

Background: Pediatric, adolescent and young adult (PAYA) patients are less active than their healthy counterparts, particularly during inpatient stays. Methods: We conducted a quality improvement initiative to increase activity levels in patients admitted to our pediatric oncology and cellular therapy unit using a Plan-Do-Study-Act (PDSA) model. An interdisciplinary team was assembled to develop an incentive-based inpatient exercise and activity program titled Totally Excited About Moving Mobility and Exercise (TEAM Me). As part of the program, patients were encouraged by their care team to remain active during their inpatient stay. As an additional incentive, patients earned stickers to display on TEAM Me door boards along with tickets that could be exchanged for prizes. Activity was assessed by documentation of physical therapy participation, tests of physical function, and surveys of staff perceptions of patient activity levels, motivations, and barriers. Results: Compared to baseline, patient refusals to participate in physical therapy decreased significantly (24% vs. 2%) (p < 0.02), and staff perceptions of patient motivation to stay active increased from 40% to 70% in the post implementation period. There were no changes in physical function tests. Conclusions: An incentive-based exercise program for young oncology inpatients greatly improved patient activity levels, participation in physical therapy and influenced professional caregivers’ beliefs.

Practice review: Evidence-based and effective management of fatigue in patients with advanced cancer

BACKGROUND

Fatigue affects most patients living with advanced cancer and is a symptom that healthcare professionals can find difficult to manage.

AIM

To provide healthcare professionals with a pragmatic overview of approaches to management of fatigue in patients with advanced cancer that are commonly recommended by guidelines and to evaluate evidence underpinning them.

DESIGN

Scoping review methodology was used to determine the strength of evidence supporting use of interventions recommended in management of fatigue in patients with advanced cancer.

DATA SOURCES

National or international guidelines were examined if they described the management of fatigue in adult cancer patients and were written within the last 6 years (2015-2021) in English. The Cochrane Database of Systematic Reviews (January 2011-December 2021) was searched for 'cancer' AND 'fatigue' in title, abstract or keywords. A PubMed search was also made.

RESULTS

Evidence indicates physical exercise interventions are effective and patients may benefit from energy conservation tactics. Evidence does not support use of psychostimulants such as methylphenidate. Limited data were found on efficacy of corticosteroids, psychological interventions, nutritional intervention, sleep optimization or complementary therapies for management of fatigue in advanced cancer.

CONCLUSION

We recommend regular assessment, review and acknowledgement of the impact of fatigue. Exercise and energy conservation should be considered. Pharmacological interventions are not endorsed as a routine approach. Many interventions currently recommended by guidelines are not supported by a robust evidence base and further research on their efficacy is required.

Exercise oncology: an emerging discipline in the cancer care continuum

Exercise is an essential component of healthy living and well-being. While there is a global acceptance of the benefits of exercise for the general population, there exists hesitancy and confusion among health-care professionals, particularly oncologists, as to whether these benefits translate to cancer patients. Patient referrals to accessible, structured exercise programs in this setting are often overlooked by physicians when formulating a cancer management plan. There is however increasing awareness and acceptance of cancer survivorship as a part of the cancer care continuum, identifying multiple factors that contribute to well-being beyond just cancer outcomes. Efforts to optimize cancer survivorship have stimulated further academic interest in the benefits of healthy living and particularly exercise oncology. There is now compelling evidence that exercise, which includes daily activities such as walking, as well as structured programs, improves multiple-cancer outcomes such as fatigue, quality of life and likely survival, and warrants consideration in the multidisciplinary care of cancer patients. International guidelines have been established that recommend counseling cancer patients with regard to healthy lifestyle changes including exercise. However, there still remains a reluctance from oncology physicians to prescribe exercise for these patients, largely due to uncertainty with regard to their patients' ability to tolerate such an intervention, coupled with insufficient understanding of the potential benefits of these programs. There also exist patient barriers and attitudes that must be overcome. Exercise strategies and bespoke programs that are tailored to the unique abilities and goals of the patients will enhance participation. To move the field forward and integrate exercise oncology into standard practice, it is imperative to raise awareness of the benefits of exercise to cancer patients and their health-care providers. This will facilitate the prescription of exercise as part of the multimodal treatment plan with the ultimate aim of promoting an active lifestyle to optimize patient care and well-being.

Supportive therapy and complementary medicine in renal cell carcinoma

PURPOSE

As part of the German interdisciplinary S3-guideline "Diagnosis, Treatment and Followup of Renal Cell Carcinoma", this article aimes to provide guidance regarding the use of supportive therapy and complementary medicine in patients with advanced or metastatic renal cell carcinoma.

METHODS

The German interdisciplinary S3-guidelines are national clinical practice guidelines that implement the highest methodological quality of evidence-based medicine. Recommendations and evidence-based statements are provided according to available evidence.

RESULTS

Supportive and palliative care are important areas of tumor treatment and require knowledge on the management of a variety of issues. This article outlines the management of tumor-related symptoms such as pain, undesired treatment-related effects, palliative care and end-of-life care in patients with renal cell carcinoma.

CONCLUSION

Patients with advanced or metastatic renal cell carcinoma should have access to supportive and palliative care according to their individual needs. There is very limited evidence regarding the impact of complementary medicine for the treatment of patients with renal cell carcinoma.

Cancer-Related Fatigue-Is There a Role for Complementary and Integrative Medicine?

PURPOSE OF REVIEW

This review aims to assess recent data on possible effective and safe complementary and integrative medicine (CIM) modalities that can be of help to patients affected by cancer that suffer from cancer-related fatigue (CRF).

RECENT FINDINGS

Cancer-related fatigue (CRF) is one of the most common, persistent, and challenging symptoms among cancer patients and survivors. Many world-leading cancer centers incorporate CIM into routine cancer care including integrating multiple approaches to address CRF. Approaches that are supported by clinical evidence on the use of CIM during and following conventional oncology treatments are being discussed in this review. The review suggests that some CIM modalities might have a potential role in alleviating cancer-related fatigue. These modalities include acupuncture, touch therapies, nutrition, nutritional supplements, stress reduction, homeopathy, and circadian rhythm management. Additional research is still needed to better support the process of integrating CIM into a routine approach to cancer-related fatigue.

Quality of Life: A Nurse-Led Physical Activity Coaching Program to Improve the Quality of Life of Patients With Cancer During the COVID-19 Pandemic

BACKGROUND

Physical activity has been shown to mitigate many of the effects of cancer treatment, yet it often is not embraced by the patient or made part of the nursing standard of care.

OBJECTIVES

This pilot study evaluates the impact of the Oncology Nursing Society's Get Up, Get Moving program, a personalized, home-based, nurse-led physical activity coaching program.

METHODS

Patients with cancer in the intervention and control groups completed the SF-36® and the Godin Leisure-Time Exercise Questionnaire at weeks 1 and 12. All patients were initially counseled on exercise. A nurse called each member of the intervention group weekly to encourage physical activity and asked about fatigue, nausea, and step count. The control group was contacted at 6 weeks and 12 weeks only.

FINDINGS

The program, coupled with nurse telephone calls, increased steps, decreased fatigue, and maintained health-related quality of life among patients in the intervention group. The control group had a decrease in steps, a decline in their SF-36 general health score, and an increase in fatigue. Nurse coaching positively affects physical activity, which may help to decrease cancer treatment side effects.

Influence of a Structured Exercise Training on Patients Reported Quality of Life in Colorectal Cancer Patients After Adjuvant Chemotherapy: A Pilot Study

Purpose: Cancer and its treatment strategies can have adverse effects on physical functioning and quality of life. Treatment strategies for better quality of life are still an unresolved issue. Physical activity is a promising treatment strategy that still has to be fully investigated. Methods: The ABCSG C07-EXERCISE study evaluated the feasibility of a 1-year exercise training after adjuvant chemotherapy in colorectal cancer patients. The present report presents the patient-reported outcomes during the exercise training. Fourteen patients of one center filled out the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30) questionnaire at 5 time points after initiating a 1-year exercise training. Results: At baseline, patients scored social functioning, emotional functioning, financial impact, insomnia, and diarrhea much worse than the German general population. After 1 year of a structured exercise training, a large improvement was reported for social functioning; moderate improvements were reported for pain, diarrhea, financial impact, and taste; and a small change for physical and emotional functioning as well as for global quality of life. Conclusions: The present study observed improvements of social, physical, and emotional functioning as well as global quality of life after 1 year of a structured exercise training in patients with locally advanced colorectal cancer after receiving adjuvant chemotherapy. To enhance compliance, sufficient support and different sport facilities should be offered. The positive effect of exercise on patient-reported outcomes, disease-free survival, and overall survival in cancer survivors have to be further investigated in further randomized clinical trials.

Anamorelin combined with physical activity, and nutritional counseling for cancer-related fatigue: a preliminary study

PURPOSE

Cancer-related fatigue (CRF) is the most frequent and debilitating symptom in patients with advanced cancer. There are limited effective treatments for CRF. The objective of this prospective longitudinal study was to evaluate the change in CRF at Day 43 after treatment with combination therapy of oral Anamorelin 100 mg daily with physical activity and nutrition counseling.

METHODS

In this study, patients with CRF [≤ 34 Functional Assessment of Chronic Illness Therapy-Fatigue subscales(FACIT-F)] received Anamorelin 100 mg orally daily with standardized physical activity and nutrition counseling for 43 days. Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Anorexia Cachexia(FAACT-ACS), Multidimensional Fatigue Symptom Inventory-Short Form(MFSI-SF), Patient-Reported Outcomes Measurement Information System(PROMIS-Fatigue), body composition, and physical performance tests were assessed at baseline, Day 15, 29, and 43. Frequency and type of side effects were determined by NCI CTAE 4.0.(NCT03035409).

RESULTS

28/45 (62%) of patients dosed were evaluable at Day 43. The mean, SD for FACIT-F subscale improvement from baseline was 4.89 (± 13.07), P = .058, MFSI-SF (G) - 3.46 (± 6.86), P = 0.013, PROMIS-fatigue - 4.14 (± 7.88), P = 0.010, FAACT ACS 3.48 (± 8.13), P = 0.035. Godin Liesure-Time physical activity questionnaire 7.41 (± 16.50), P = 0.038. Weight (kg) 1.81 (± 2.63), P = 0.005, and Lean Body Mass 1.54 (± 1.85), P = 0.001, IGF-1 36.50 (± 48.76), P = 0.015. There was no significant improvement in physical performance outcomes. No adverse events > grade 3 related to the study drug were reported.

CONCLUSION

The use of the combination therapy was associated with improvement of CRF (FACIT-F fatigue, PROMIS-fatigue, MFSI-SF-general), activity (Godin-leisure time), anorexia (FAACT), body composition, and IGF-1 levels. Further studies using combination therapy for CRF are justified.

Feasibility and Acceptability of Light Therapy to Reduce Fatigue in Adolescents and Young Adults Receiving Cancer-Directed Therapy

OBJECTIVE/BACKGROUND

Fatigue is one of the most consistent and distressing symptoms reported by adolescent/young adult (AYA) oncology patients. Bright white light (BWL) is used to treat fatigue in adult oncology but has not been explored in AYA oncology patients. The purpose of the current study was to determine the feasibility and acceptability of BWL for AYA who were receiving cancer-directed therapy.

PARTICIPANTS

51 AYA patients with newly diagnosed solid tumors, including lymphoma.

METHODS

Participants were randomized to dim red light (DRL, n = 25) or BWL (n = 26) from devices retrofitted with adherence monitors for 30 minutes upon awakening daily for 8 weeks. Side effects were assessed via modified Systematic Assessment for Treatment-Emergent Effects (SAFTEE). Participants completed the PedsQL Multidimensional Fatigue Scale.

RESULTS

Of patients approached, 73% consented and participated. Mean adherence was 57% of days on study with 30.68 average daily minutes of usage. BWL did not cause more extreme treatment-emergent effects over DRL. Patients in the BWL group demonstrated significant improvement on all fatigue outcomes by both self-report and parent proxy report, which was not observed in the DRL group.

CONCLUSIONS

This is the first study to evaluate the feasibility and acceptability of light therapy to reduce fatigue in AYA patients receiving cancer-directed therapy. These findings demonstrate the feasibility and acceptability of the intervention and provide preliminary evidence of the potential benefits of BWL, which warrants further study in a confirmatory efficacy trial.ClinicalTrials.gov Identifier Number: NCT02429063.

An Exploratory Analysis of the Association Between Catechol-O-Methyltransferase and Response to a Randomized Open-Label Placebo Treatment for Cancer-Related Fatigue

Previous studies have identified catechol-O-methyltransferase (COMT), as a key enzyme influencing sympathetic function. Although the COMT SNP rs4680 and rs4818, are well-studied, little is known about their influence on cancer-related fatigue (CrF) and placebo response. In this study, we examined whether genetic variation in COMT, at the functional SNP rs4680 and linked rs4818, influenced open-label placebo (OLP) responses found in cancer survivors reporting moderate to severe CrF. We randomized cancer survivors (N = 74) reporting moderate-to-severe CrF to receive OLP or to treatment-as-usual (TAU) and assessed if rs4680 and rs4818 were associated with changes in fatigue severity and fatigue-distressed quality of life. At the end of the initial 21 days, the treatments were crossed over and both groups were re-assessed. Participants with the rs4680 high-activity G-allele (G/G or G/A) or rs4818 C/G genotypes reported significant decreases in fatigue severity and improvements in fatigue-distressed quality of life. The COMT rs4818 findings replicated findings in a similar study of OLP in cancer fatigue. Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT02522988.

Paired exercise has superior effects on psychosocial health compared to individual exercise in female cancer patients

Purpose

Exercise improves the quality of life (QOL) in cancer patients recovering from treatment. Since group exercise fosters cohesion, we sought to determine if paired exercise would have similar, positive effects. An experiential study design was used to compare the effect of exercise (12 weeks) on psychosocial health in paired versus individually trained cancer patients.

Methods

Female cancer patients (n = 28) who completed cancer treatment were placed into either the singly trained or paired group. Groups were matched for cardiorespiratory fitness (peak oxygen consumption, single: 24.1 ± 7.4, pair: 24.8 ± 6.3 ml/kg/min) and age (single: 58 ± 12, pair: 58 ± 9 years). Patients participated in 36, 90-min exercise sessions in accordance with exercise recommendations. QOL (Functional Assessment of Cancer Therapy-General, FACT-G), depressive, fatigue, and insomnia symptoms were measured before, midway, and after the intervention. Fitness was measured pre- and post-intervention. Participants did not meet prior to the intervention. Two-way ANOVAs and multiple comparisons tests were used to detect differences (p < 0.05).

Results

Emotional well-being and total FACT-G scores were significantly improved in the paired but not individually trained patients. Depressive symptoms were significantly improved at mid- and final time points in the paired group. Paired patients reported significant improvements in insomnia symptoms from pre- to mid-intervention. Depressive and insomnia symptoms in the individually trained group were unchanged. A significant main effect of group was detected in fatigue scores in patients who were not chronically tired at baseline (F(1, 12) = 6.318, p = 0.0272). Both groups exhibited similar improvements in fitness.

Conclusion

Paired exercisers had greater benefits in QOL, emotional well-being, and insomnia and depressive symptoms compared to individual exercisers.

A Physical Activity Mobile Game for Hematopoietic Stem Cell Transplant Patients: App Design, Development, and Evaluation

BACKGROUND

Physical activity mobile apps may encourage patients with cancer to increase exercise uptake, consequently decreasing cancer-related fatigue. While many fitness apps are currently available for download, most are not suitable for patients with cancer due to the unique barriers these patients face, such as fatigue, pain, and nausea.

OBJECTIVE

The aim of this study is to design, develop, and perform alpha testing of a physical activity mobile health game for hematopoietic stem cell transplant (HSCT) patients. The ultimate future goal of this project is to motivate HSCT patients to increase physical activity and provide them with a safe and fun way to exercise.

METHODS

A mobile health game called Walking Warrior was designed as a puzzle game where tiles are moved and matched. Walking Warrior interfaces with an open-source step counter and communicates with a central online MySQL database to record game play and walking performance. The game came to fruition after following an iterative process model with several prototypes. Game developers and bone marrow transplant nurses were recruited to perform an expert usability evaluation of the Walking Warrior prototype by completing a heuristic questionnaire and providing qualitative suggestions for improvement. Experts also made qualitative recommendations for improvements on speed, movement of tiles, appearance, and accuracy of the step counter. We recruited 5 additional usability evaluators who searched for and compared 4 open-source step counter programs, then qualitatively compared them for accuracy, robustness, cheat proofing, ease of use, and battery drain issues. Patient recruitment is planned at a later stage in this project. This paper only describes software design, development, and evaluation, rather than behavioral evaluation (ie, impact on physical activity), which is the long-term goal of this project.

RESULTS

Internal consistency and the instrument's reliability evaluation results from 1 clinical expert and 4 technical experts were deemed excellent (Cronbach α=.933). A hierarchical cluster analysis of the questionnaire item responses for similarity/dissimilarity among the experts indicated that the two expert groups were not clustered into two separate groups in the dendrogram. This indicates that the item responses were not affected by profession. Factor analyses indicate that responses from the 40-item questionnaire were classified into five primary factors. The associated descriptive statistics for each of these categories were as follows (on a scale of 1 to 5): clarity and ease (median 4; mean 3.7, SD 0.45), appropriateness (median 4; mean 3.7, SD 0.49), game quality (median 3.5; mean 3.3, SD 0.42), motivation to walk (median 3; mean 3.1, SD 0.58), and mental effort (median 3.5; mean 3.1, SD 1.27).

CONCLUSIONS

The evaluation from experts and clinicians provided qualitative information to further improve game design and development. Findings from the expert usability evaluation suggest the game's assets of clarity, ease of use, appropriateness, quality, motivation to walk, and mental effort were all favorable. This mobile game could ultimately help patients increase physical activity as an aid to recovery.

Multidimensional fatigue in patients with nasopharyngeal carcinoma receiving concurrent chemoradiotherapy: incidence, severity, and risk factors

PURPOSE

To explore the incidence, severity, and risk factors of multidimensional fatigue in patients with nasopharyngeal carcinoma (NPC) receiving concurrent chemoradiotherapy (CCRT).

METHODS

This prospective study included 79 patients with NPC in Guangzhou (China) from June 2015 to July 2018. Data were collected before and after CCRT, including demographic and clinical characteristics, nutritional parameters, and fatigue scores, based on completion of the Multiple Dimensional Inventory-20 Questionnaire, with five subscales: General Fatigue, Mental Fatigue, Physical Fatigue, Reduced Activity, and Reduced Motivation.

RESULTS

Increased general fatigue was found to be associated with lower lymphocyte count and body mass index <23 kg/m². Increased physical fatigue was related to age > 42 years. Higher scores for reduced activity were associated with age > 42 years, female sex, and lower serum sodium. Increased mental fatigue was related with lower lymphocyte count and unemployment; and increased total fatigue was associated with lower lymphocyte count, age > 42 years, and 3-6 courses of treatment. Furthermore, 3-6 courses of treatment was an independent predictor of severe general fatigue, while age >42 years was an independent predictor of severe physical fatigue. Importantly, cancer stage IVB and 3-6 courses of treatment could predict severe total fatigue.

CONCLUSIONS

Our data demonstrate that fatigue is increased in all dimensions in NPC patients following CCRT, and that the predictors differ for each fatigue dimension. These results could guide the development of targeted interventions that may reduce the impact of cancer-related fatigue in patients with NPC.

Exercise Training as Therapeutic Approach in Cancer Cachexia: A Review of Potential Anti-inflammatory Effect on Muscle Wasting

Cachexia is a multifactorial inflammatory syndrome with high prevalence in cancer patients. It is characterized by a metabolic chaos culminating in drastic reduction in body weight, mainly due to skeletal muscle and fat depletion. Currently, there is not a standard intervention for cachexia, but it is believed that a dynamic approach should be applied early in the course of the disease to maintain or slow the loss of physical function. The present review sought to explain the different clinical and experimental applications of different models of exercise and their contribution to a better prognosis of the disease. Here the advances in knowledge about the application of physical training in experimental models are elucidated, tests that contribute substantially to elucidate the cellular and biochemical mechanisms of exercise in different ways, as well as clinical trials that present not only the impacts of exercise in front cachexia but also the challenges of its application in clinical practice.

Low physical activity, fatigue and depression in breast cancer survivors: Moderation by levels of IL-6 and IL-8

BACKGROUND AND AIMS

Although previous studies suggested that depressed mood and fatigue among cancer survivors are associated with chronic inflammation, the effect of cytokines on the relation between physical activity and fatigue and depressed mood is characterized by inconsistent results. The aim was to examine levels of pro-inflammatory (IL-6, IL-8, TNFα, IL-12) and anti-inflammatory (IL-10) cytokines in relation to the effects of physical activity on fatigue and depressed mood.

METHODS

Breast cancer survivors (n = 108; stages I-III), aged >20 and who were 1-6 months postchemotherapy were recruited consecutively. Participants completed the Fatigue Symptom Inventory and Center for Epidemiologic Studies Depression Scale and reported physical activity details; 10 cc of blood were drawn for assessment of levels of IL-6, IL-8, IL-10, Il-12, and TNFα in serum.

RESULTS

Only IL-6 and IL-8 were associated with fatigue and depressed mood. Controlling for background variables, physical activity and IL-6 were significantly associated with fatigue, but only physical activity was significantly associated with depressed mood. A moderated effect of IL-6 and IL-8 was found in the association of physical activity and fatigue, indicating that this association is significant only in individuals with lower levels of IL-6 or IL-8.

CONCLUSIONS

Fatigue and depressed mood are differently associated with pro-inflammatory cytokines. In addition, IL-6 and IL-8 are main cytokines affected by physical activity. The study stresses the need to provide information and tailored guidance for cancer survivors for maintaining an active lifestyle into survivorship and the importance of allocating resources for programs to encourage active lifestyles among cancer survivors. Caution should be exercised in the interpretation of the results due to the cross-sectional design and possibility of bidirectional associations between the study variables.

Moderators of Exercise Effects on Cancer-related Fatigue: A Meta-analysis of Individual Patient Data

PURPOSE

Fatigue is a common and potentially disabling symptom in patients with cancer. It can often be effectively reduced by exercise. Yet, effects of exercise interventions might differ across subgroups. We conducted a meta-analysis using individual patient data of randomized controlled trials (RCT) to investigate moderators of exercise intervention effects on cancer-related fatigue.

METHODS

We used individual patient data from 31 exercise RCT worldwide, representing 4366 patients, of whom 3846 had complete fatigue data. We performed a one-step individual patient data meta-analysis, using linear mixed-effect models to analyze the effects of exercise interventions on fatigue (z score) and to identify demographic, clinical, intervention- and exercise-related moderators. Models were adjusted for baseline fatigue and included a random intercept on study level to account for clustering of patients within studies. We identified potential moderators by testing their interaction with group allocation, using a likelihood ratio test.

RESULTS

Exercise interventions had statistically significant beneficial effects on fatigue (β = -0.17; 95% confidence interval [CI], -0.22 to -0.12). There was no evidence of moderation by demographic or clinical characteristics. Supervised exercise interventions had significantly larger effects on fatigue than unsupervised exercise interventions (βdifference = -0.18; 95% CI -0.28 to -0.08). Supervised interventions with a duration ≤12 wk showed larger effects on fatigue (β = -0.29; 95% CI, -0.39 to -0.20) than supervised interventions with a longer duration.

CONCLUSIONS

In this individual patient data meta-analysis, we found statistically significant beneficial effects of exercise interventions on fatigue, irrespective of demographic and clinical characteristics. These findings support a role for exercise, preferably supervised exercise interventions, in clinical practice. Reasons for differential effects in duration require further exploration.

Muscle function impairment in cancer patients in pre-cachexia stage

Cancer cachexia has been reported to be directly responsible for at least 20% of cancer deaths. Management of muscle wasting in cancer-associated cachexia appears to be of pivotal importance for survival of patients. In this regard, it would be interesting to identify before its patent appearance eventual functional markers of muscle damage, to plan specific exercise protocols to counteract cachexia. The muscle function of 13 oncologic patients and 15 controls was analyzed through: i) analysis of the oxidative metabolism, indirectly evaluated trough dosage of blood lactate levels before and after a submaximal incremental exercise on a treadmill; ii) analysis of strength and, iii) endurance, in both lower and upper limbs muscles, employing an isokinetic dynamometer. Statistical analyses were carried out to compare the muscle activities between groups. Analysis of oxidative metabolism during the incremental exercise on a treadmill showed that patients performed a shorter exercise than controls. Lactate levels were significantly higher in patients both at baseline and after the task. Muscle strength analysis in patients group showed a reduction of Maximum Voluntary Contraction during the isometric contraction and, a tendency to fatigue during endurance task. Data emerging from this study highlight an impairment of muscle oxidative metabolism in subjects affected by a pre-cachexia stage of cancer. A trend of precocious fatigability and an impairment of muscle strength production were also observed. This evidence underlines the relevance of assessing muscle function in order to develop novel rehabilitative approaches able to counteract motor impairment and eventually to prevent cachexia in these patients.

Muscle function impairment in cancer patients in pre-cachexia stage

Cancer cachexia has been reported to be directly responsible for at least 20% of cancer deaths. Management of muscle wasting in cancer-associated cachexia appears to be of pivotal importance for survival of patients. In this regard, it would be interesting to identify before its patent appearance eventual functional markers of muscle damage, to plan specific exercise protocols to counteract cachexia. The muscle function of 13 oncologic patients and 15 controls was analyzed through: i) analysis of the oxidative metabolism, indirectly evaluated trough dosage of blood lactate levels before and after a submaximal incremental exercise on a treadmill; ii) analysis of strength and, iii) endurance, in both lower and upper limbs muscles, employing an isokinetic dynamometer. Statistical analyses were carried out to compare the muscle activities between groups. Analysis of oxidative metabolism during the incremental exercise on a treadmill showed that patients performed a shorter exercise than controls. Lactate levels were significantly higher in patients both at baseline and after the task. Muscle strength analysis in patients group showed a reduction of Maximum Voluntary Contraction during the isometric contraction and, a tendency to fatigue during endurance task. Data emerging from this study highlight an impairment of muscle oxidative metabolism in subjects affected by a pre-cachexia stage of cancer. A trend of precocious fatigability and an impairment of muscle strength production were also observed. This evidence underlines the relevance of assessing muscle function in order to develop novel rehabilitative approaches able to counteract motor impairment and eventually to prevent cachexia in these patients.

Fatigue, barriers to physical activity and predictors for motivation to exercise in advanced Cancer patients

Background

In order to counteract fatigue, physical activity (PA) is recommended for all stages of cancer. However, only few advanced cancer patients (ACP) are physically active. Quantitative data with high numbers of ACP reporting barriers to PA are missing. This study aimed to identify barriers to PA in ACP with tiredness/weakness and investigate their motivation towards it.

Methods

Outpatients with metastatic cancer receiving cancer care at a German Cancer Center reporting moderate/severe tiredness/weakness during self-assessment (MIDOS II) were enrolled. We assessed Fatigue-(FACF-F) and Depression (PHQ8) Scores, demographics, cancer-specific parameters, motivation for PA, physical, psychological and social barriers.

Results

141 of 440 eligible patients (32.0%) with different diagnoses agreed to participate. Patients frequently reported “I feel weakened due to my tumor therapy” (n = 108; 76.6%), physical symptoms (tiredness, weakness, dyspnea, joint-problems, pain, nausea [n = 107; 75.9%]) and fatigue (n = 99; 70.2%) as barriers to PA. However, no significant group differences regarding these barriers were found between physically active and inactive patients. Social barriers were rarely chosen. Motivated patients were 5.6 times more likely to be physically active (p < 0.001), also motivation turned out to be the strongest predictor for a physically active behavior (β = 1.044; p = 0.005). Motivated attitude towards PA was predicted by fatigue (β = − 2.301; p = 0.008), clinically relevant depression (β = − 1.390, p = 0.039), knowledge about PA and quality of life (QoL) (β = 0.929; p = 0.002), PA before diagnosis (β = 0.688; p = 0.005 and Interest in exercise program (β = 0.635; p = 0.008).

Conclusion

“I feel weakened due to my tumor therapy” is the most reported barrier to PA among both, physically and inactive patients. Motivation for PA is the strongest predictor of performing PA. Interest in PA, knowledge about PA/QoL and PA before diagnosis are main predictors of a motivated attitude. Absence/presence of social barriers did not associate with motivation, fatigue and depression proved to be a negative predictor. Programs including information, motivational counseling and individualized training should be offered for ACP to overcome barriers and reduce fatigue.

Efficacy and safety of bupropion in cancer-related fatigue, a randomized double blind placebo controlled clinical trial

BACKGROUND AND OBJECTIVES

Cancer-related fatigue (CRF) is one of the most prevalent complications experienced by cancer patients during and after the process of treatment. Despite conducting a lot of studies, there is no approved therapy to help manage CRF. This study aims to investigate the efficacy of bupropion on CRF.

MATERIALS AND METHODS

In this double-blind randomized placebo-controlled clinical trial, a total of 30 eligible cancer patients suffering from fatigue were randomly divided into two groups (15 patients in each group). Bupropion was administered 75 mg/day for the first three days and 150 mg/day (divided in two doses) till the end of the study at week 6. Fatigue as the primary outcome was measured by BFI (Brief Fatigue Inventory) and FACIT-Fatigue (Functional Assessment of Chronic Illness Therapy) scales. Secondary outcomes included HADS (Hospital Anxiety and Depression Scale) and performance status (PS) measured by Karnofsky and ECOG (Eastern Cooperative Oncology Group) scales. Assessments were done at baseline, end of the second and sixth week.

RESULTS

There was no significant difference between placebo and bupropion at baseline and the end of second week. Significant difference was seen between two groups at the end of week six (P = 0.006 based on BFI) in favor of bupropion. In-group assessment showed improvement in fatigue levels in both groups during study time (P = 0.000 based on BFI for both bupropion and placebo). Secondary outcomes (e.g., HADS and PS) were not different at baseline and the end of second week. However, at the end of week six, the difference was significant in favor of bupropion.

CONCLUSION

A six-week trial of bupropion reduces the CRF and improves the PS of cancer patients.

Long-Term Fatigue and Cognitive Disorders in Breast Cancer Survivors

Survivors of early-stage breast cancer may report treatment-related side effects that persist for several years after the end of primary treatment. Among these, fatigue and cognitive disorders are frequent complaints and can negatively impact quality of life. Cancer-related fatigue is a very prevalent and distressing long-term side effect among breast cancer survivors that typically improves after completion of treatment, although many patients report severe fatigue several years post-treatment. Cognitive disorders are also common among survivors of breast cancer, especially if treated with chemotherapy. These symptoms are usually mild-to-moderate and often transient. Cognitive recovery is frequently observed within months or a few years after completion of chemotherapy or endocrine therapy. However, some breast cancer survivors may have persistent cognitive difficulties. Several types of interventions have proved to be beneficial in reducing cancer-related fatigue and cognitive difficulties. Most of these interventions for cancer-related fatigue are thought to be effective by reducing inflammation or disrupting pro-inflammatory circuits. Further studies are needed on cognitive management that has showed promising results. This narrative review summarizes the state of the art regarding long-term fatigue and cognitive disorders in patients with early breast cancer, describing prevalence, impact, pathophysiology, and risk factors, and focusing on available interventions.
