Is increasing physical activity necessary to diminish fatigue during cancer treatment? Comparing cognitive behavior therapy and a brief nursing intervention with usual care in a multicenter randomized controlled trial

Management of Fatigue in Adult Survivors of Cancer: ASCO-Society for Integrative Oncology Guideline Update

PURPOSE

To update the ASCO guideline on the management of cancer-related fatigue (CRF) in adult survivors of cancer.

METHODS

A multidisciplinary panel of medical oncology, geriatric oncology, internal medicine, psychology, psychiatry, exercise oncology, integrative medicine, behavioral oncology, nursing, and advocacy experts was convened. Guideline development involved a systematic literature review of randomized controlled trials (RCTs) published in 2013-2023.

RESULTS

The evidence base consisted of 113 RCTs. Exercise, cognitive behavioral therapy (CBT), and mindfulness-based programs led to improvements in CRF both during and after the completion of cancer treatment. Tai chi, qigong, and American ginseng showed benefits during treatment, whereas yoga, acupressure, and moxibustion helped to manage CRF after completion of treatment. Use of other dietary supplements did not improve CRF during or after cancer treatment. In patients at the end of life, CBT and corticosteroids showed benefits. Certainty and quality of evidence were low to moderate for CRF management interventions.

RECOMMENDATIONS

Clinicians should recommend exercise, CBT, mindfulness-based programs, and tai chi or qigong to reduce the severity of fatigue during cancer treatment. Psychoeducation and American ginseng may be recommended in adults undergoing cancer treatment. For survivors after completion of treatment, clinicians should recommend exercise, CBT, and mindfulness-based programs; in particular, CBT and mindfulness-based programs have shown efficacy for managing moderate to severe fatigue after treatment. Yoga, acupressure, and moxibustion may also be recommended. Patients at the end of life may be offered CBT and corticosteroids. Clinicians should not recommend L-carnitine, antidepressants, wakefulness agents, or routinely recommend psychostimulants to manage symptoms of CRF. There is insufficient evidence to make recommendations for or against other psychosocial, integrative, or pharmacological interventions for the management of fatigue.Additional information is available at www.asco.org/survivorship-guidelines.

The effect of psychologically informed practice with behavioural graded activity in cancer survivors: systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to determine the effectiveness of psychologically informed practice (PIP) with behavioural graded activity (BGA) compared to (1) waitlist controls (WLC), (2) other interventions (OI), (3) PIP alone or (4) BGA alone in cancer patients and survivors (CPaS).

METHODS

PubMed, Web of Science and Embase were screened for randomised controlled trials encompassing BGA + PIP in CPaS. Effect sizes were inventoried for outcomes regarding physical activity (PA), quality of life (QoL) and debilitating symptoms (DS), which were assessed at four time points: post-intervention (PI), follow-up F1 (1 to 3 months), F2 (4 to 6 months) and F3 (> 6 months). The quality of the evidence was classified by the GRADE approach.

RESULTS

Thirty-three studies were found eligible, comprising 4330 participants. Significant effects with low heterogeneity of PIP + BGA comparing to WLC were found for anxiety (SMD - 1.29 [-1.71; - 0.86]), depression (SMD - 0.79 [- 1.10; - 0.48]), functional impairment (SMD - 0.72 [- 0.95; - 0.50]), PA (self-reported: (SMD - 0.58 [- 0.84; - 0.32]) and objectively measured: (SMD - 0.51 [- 0.90; - 0.13])) and social impairment (SMD - 0.33 [- 0.58; - 0.08]). When comparing PIP + BGA to OI, fatigue (SMD - 0.35 [- 0.51; - 0.20]) and PA (SMD - 0.26 [- 0.41; - 0.11]) at PI, and fatigue (SMD - 0.34 [- 0.58; - 0.10]) at F1 were found significant with low heterogeneity. No significant effects were observed in the meta-analyses of studies comparing PIP + BGA to BGA or PIP alone.

CONCLUSIONS

PIP with BGA has a favourable effect on DS, PA and QoL in CPaS when compared to non-behavioural interventions such as WLC, usual care and education. However, further research is needed on 'how' and 'when' PIP + BGA should be provided in cancer rehabilitation.

IMPLICATIONS FOR CANCER SURVIVORS

PIP + BGA has the potential to facilitate CPaS to reach the recommended amount of PA and reduce DS.

Moderators of exercise effects on self-reported cognitive functioning in cancer survivors: an individual participant data meta-analysis

PURPOSE

This individual participant data meta-analysis (IPD-MA) assesses exercise effects on self-reported cognitive functioning (CF) and investigates whether effects differ by patient-, intervention-, and exercise-related characteristics.

METHODS

IPD from 16 exercise RCTs, including 1987 patients across multiple types of non-metastatic cancer, was pooled. A one-stage IPD-MA using linear mixed-effect models was performed to assess exercise effects on self-reported CF (z-score) and to identify whether the effect was moderated by sociodemographic, clinical, intervention- and exercise-related characteristics, or fatigue, depression, anxiety, and self-reported CF levels at start of the intervention (i.e., baseline). Models were adjusted for baseline CF and included a random intercept at study level to account for clustering of patients within studies. A sensitivity analysis was performed in patients who reported cognitive problems at baseline.

RESULTS

Minimal significant beneficial exercise effects on self-reported CF (β=-0.09 [-0.16; -0.02]) were observed, with slightly larger effects when the intervention was delivered post-treatment (n=745, β=-0.13 [-0.24; -0.02]), and no significant effect during cancer treatment (n=1,162, β=-0.08 [-0.18; 0.02]). Larger effects were observed in interventions of 12 weeks or shorter (β=-0.14 [-0.25; -0.04]) or 24 weeks or longer (β=-0.18 [-0.32; -0.02]), whereas no effects were observed in interventions of 12-24 weeks (β=0.01 [-0.13; 0.15]). Exercise interventions were most beneficial when provided to patients without anxiety symptoms (β=-0.10 [-0.19; -0.02]) or after completion of treatment in patients with cognitive problems (β=-0.19 [-0.31; -0.06]). No other significant moderators were identified.

CONCLUSIONS

This cross-cancer IPD meta-analysis observed small beneficial exercise effects on self-reported CF when the intervention was delivered post-treatment, especially in patients who reported cognitive problems at baseline.

IMPLICATIONS FOR CANCER SURVIVORS

This study provides some evidence to support the prescription of exercise to improve cognitive functioning. Sufficiently powered trials are warranted to make more definitive recommendations and include these in the exercise guidelines for cancer survivors.

Effectiveness of the perioperative encounter in promoting regular exercise and physical activity: a systematic review and meta-analysis

BACKGROUND

Low levels of physical activity (PA) are associated with poorer health outcomes. The perioperative encounter (extending from initial contact in primary care to beyond discharge from hospital) is potentially a good time to intervene, but data regarding the effectiveness of interventions are scarce. To address this, we systematically reviewed existing literature to evaluate the effectiveness of interventions applied perioperatively to facilitate PA in the medium to long-term (at least six months after the intervention).

METHODS

In this systematic review and meta-analysis, we searched Central Register of Controlled Trials (CENTRAL, Cochrane Library), MEDLINE, CINAHL, Embase, PsycInfo, and SPORTDiscus from database inception to October 22nd 2020, with an updated search done on August 4th 2022. We searched clinical trials registers, and conducted forward- and backward-citation searches. We included randomised controlled trials and quasi-randomised trials comparing PA interventions with usual care, or another PA intervention, in adults who were scheduled for, or had recently undergone, surgery. We included trials which reported our primary outcomes: amount of PA or whether participants were engaged in PA at least six months after the intervention. A random effects meta-analysis was used to pool data across studies as risk ratios (RR), or standardised mean differences (SMDs), which we interpreted using Cohen. We used the Cochrane risk of bias tool and used GRADE to assess the certainty of the evidence. This study is registered with PROSPERO, CRD42019139008.

FINDINGS

We found 57 trials including 8548 adults and compared 71 interventions facilitating PA. Most interventions were started postoperatively and included multiple components. Compared with usual care, interventions may slightly increase the number of minutes of PA per day or week (SMD 0.17, 95% CI 0.09-0.26; 14 studies, 2172 participants; I² = 0%), and people's engagement in PA at the study's end (RR 1.19, 95% CI 0.96-1.47; 9 studies, 882 participants; I² = 25%); this was moderate-certainty evidence. Some studies compared two different types of interventions but it was often not feasible to combine data in analysis. The effect estimates generally indicated little difference between intervention designs and we judged all the evidence for these comparisons to be very low certainty. Thirty-six studies (63%) had low risk of selection bias for sequence generation, 27 studies (47%) had low risk of bias for allocation concealment, and 56 studies (98%) had a high risk of performance bias. For detection bias for PA outcomes, we judged 30 studies (53%) that used subjective measurement tools to have a high risk of detection bias.

INTERPRETATION

Interventions delivered in the perioperative setting, aimed at enhancing PA in the medium to long-term, may have overall benefit. However, because of imprecision in some of the findings, we could not rule out the possibility of no change in PA.

Fatigue trajectories during pediatric ALL therapy are associated with fatigue after treatment: a national longitudinal cohort study

OBJECTIVE

Fatigue is one of the most prevalent and distressing symptoms reported by survivors of childhood cancer. There is currently a lack of longitudinal studies on cancer-related fatigue, and especially on the relationship between the course of fatigue during treatment and fatigue at follow-up. The purpose of the current study was therefore to investigate if the course of fatigue during treatment, treatment intensity, serious adverse events, sex, or age at diagnosis are associated with cancer-related fatigue after treatment.

METHODS

Participants were 92 children and adolescents diagnosed with acute lymphoblastic leukemia (mean age at diagnosis was 6.26 years). Fatigue was measured with PedsQL multidimensional fatigue scale proxy reports 5 months after diagnosis, 12 months after diagnosis, 24 months after diagnosis, and at follow-up 12 months after end of treatment. The effect of patient and treatment characteristics on fatigue reported at follow-up was tested through logistic regression analyses.

RESULTS

The course of fatigue during treatment significantly predicted fatigue reported at follow-up for general fatigue (p = .038, OR = 9.20), sleep/rest fatigue (p = .011, OR = 15.48), and cognitive fatigue (p < .001, OR = 10.78). None of the other variables were associated with fatigue at follow-up for any of the subscales.

CONCLUSIONS

The findings demonstrate that fatigue reported during treatment can predict fatigue at follow-up. These results stress the need for longitudinal assessments. Healthcare professionals need to be aware that pediatric patients who are fatigued during treatment need to receive additional attention and timely interventions since cancer-related fatigue will not resolve by itself in the first year after end of treatment.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Effectiveness comparisons of various psychosocial therapies for cancer-related fatigue: A Bayesian network meta-analysis

OBJECTIVES

The purpose of this network meta-analysis (NMA) is to compare the effect of several psychosocial therapies on CRF critically.

METHODS

We applied systematic strategies based on eight databases, namely the Cochrane Central Register of Controlled Trials, PubMed, Embase, PsycINFO, China Biology Medicine (CBM), Wan Fang database, VIP, and China National Knowledge Infrastructure (CNKI) database to preliminary literature retrieval to identify relevant randomized controlled trials (RCTs). Studies, including adult patients (≥18 years) diagnosed with cancer, were eligible regardless of cancer stage and current treatment. We carried out an expression analysis for comparing the efficacy of various psychosocial therapies using Bayesian NMA. A battery of analyses and assessments, such as conventional meta-analysis and risk of bias, were performed concurrently.

RESULTS

We identified 41 RCTs including six different psychosocial interventions (4422 participants), namely cognitive-behavioral therapy (CBT), mindfulness-based stress reduction therapy (MBSR), psychoeducational therapy (PE), stress management therapy (SMT), meditation therapy (MT) and comprehensive therapy (CT). Our NMA results showed that three psychosocial intervention therapies were effective for CRF in cancer patients. The most effective psychosocial intervention was MBSR (SMD = -1.23, CrI: -1.88, -0.59, SUCRA = 83.33%), followed by PE (SMD = -0.86, CrI: -1.53, -0.18, SUCRA = 58.51%) and CBT (SMD = -0.84, CrI: -1.31, -0.37, SUCRA = 57.67%).

CONCLUSIONS

Our study showed that MBSR was most likely to be the best psychosocial intervention to relieve CRF in cancer patients. Medical staff should pay attention to applying MBSR to cancer patients in future clinical care.

Fatigue self-management education in persons with disease-related fatigue: A comprehensive review of the effectiveness on fatigue and quality of life

OBJECTIVES

To systematically synthesize the effectiveness of fatigue self-management education (SME) on fatigue and quality of life (QoL) in persons with disease-related fatigue, and to describe the intervention characteristics.

METHODS

We systematically reviewed the literature on SMEs in people with disease-related fatigue. We included randomized controlled trials (RCT), which aimed to improve self-management skills for fatigue in daily life. We synthesized the effectiveness and mapped the intervention characteristics.

RESULTS

We included 26 RCTs studying samples from eight disease groups. At follow-up, 46% studies reported statistically significant improvements on fatigue and 46% on QoL. For persons with cancer 6/8 and multiple sclerosis 8/10 RCTs showed positive evidence in favor of SME. The range of effect sizes was wide (d: 0.0 ->0.8). Delivery modalities (inpatient, outpatient, home), interactions (individual, group, remote), and duration [range (h): 1-17.5] varied.

CONCLUSIONS

The overall evidence on the effectiveness of SMEs on fatigue and QoL is limited and inconsistent. For persons with cancer and multiple sclerosis, the evidence provides a positive effect. The RCTs with medium to large effect on QoL indicate the potential benefit of SMEs.

PRACTICAL IMPLICATION

Duration and peer interaction should be considered when tailoring SMEs to populations and contexts.

Meta-Analysis of Randomized Controlled Trials on Yoga, Psychosocial, and Mindfulness-Based Interventions for Cancer-Related Fatigue: What Intervention Characteristics Are Related to Higher Efficacy?

Simple Summary

Many individuals with cancer suffer from persistent exhaustion due to cancer therapy, known as cancer-related fatigue (CRF). Yoga, psychosocial, and mindfulness-based interventions are recommended to reduce CRF. However, it is not clear yet how interventions need to be designed to maximize their efficacy. This meta-analysis aimed to identify intervention characteristics associated with greater reductions in CRF. A total of 70 interventions with 6387 participants were included in the analysis. Our results found a positive effect of yoga, psychosocial, and mindfulness-based interventions, while all invention types revealed large differences in intervention effects. In psychosocial interventions, using a group setting and working on cognition was related to higher efficacy. Regarding yoga and mindfulness-based interventions, no specific intervention characteristics emerged as more favorable than others. Overall, this meta-analysis suggests opportunities to optimize psychosocial interventions for CRF, whereas the design of yoga and mindfulness-based interventions seems to allow for variation.

Abstract

Cancer-related fatigue (CRF) is a burdensome sequela of cancer treatments. Besides exercise, recommended therapies for CRF include yoga, psychosocial, and mindfulness-based interventions. However, interventions conducted vary widely, and not all show a significant effect. This meta-analysis aimed to explore intervention characteristics related to greater reductions in CRF. We included randomized controlled trials published before October 2021. Standardized mean differences were used to assess intervention efficacy for CRF and multimodel inference to explore intervention characteristics associated with higher efficacy. For the meta-analysis, we included 70 interventions (24 yoga interventions, 31 psychosocial interventions, and 15 mindfulness-based interventions) with 6387 participants. The results showed a significant effect of yoga, psychosocial, and mindfulness-based interventions on CRF but with high heterogeneity between studies. For yoga and mindfulness-based interventions, no particular intervention characteristic was identified to be advantageous for reducing CRF. Regarding psychosocial interventions, a group setting and work on cognition were related to higher intervention effects on CRF. The results of this meta-analysis suggest options to maximize the intervention effects of psychosocial interventions for CRF. The effects of yoga and mindfulness-based interventions for CRF appear to be independent of their design, although the limited number of studies points to the need for further research.

Measuring Clinical, Biological, and Behavioral Variables to Elucidate Trajectories of Patient (Reported) Outcomes: The PROFILES Registry

To take cancer survivorship research to the next level, it's important to gain insight in trajectories of changing patient (reported) outcomes and impaired recovery after cancer. This is needed as the number of survivors is increasing and a large proportion is confronted with changing health after treatment. Mechanistic research can facilitate the development of personalized risk-stratified follow-up care and tailored interventions to promote healthy cancer survivorship. We describe how these trajectories can be studied by taking the recently extended Dutch population-based PROFILES (Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship) registry as an example. PROFILES combines longitudinal assessment of patient-reported outcomes with novel, ambulatory and objective measures (e.g., activity trackers; blood draws; hair samples; online food diaries; online cognitive tests; weighing scales; online symptoms assessment), and cancer registry and pharmacy databases. Furthermore, we discuss methods to optimize the use of a multidomain data collection like return of individual results to participants which may not only improve patient empowerment but also long-term cohort retention. Also, advanced statistical methods are needed to handle high-dimensional longitudinal data (with missing values) and provide insight into trajectories of changing patient (reported) outcomes after cancer. Our coded data can be used by academic researchers around the world. Registries like PROFILES, that go beyond boundaries of disciplines and institutions, will contribute to better predictions of who will experience changes and why. This is needed to prevent and mitigate long-term and late effects of cancer (treatment) and to identify new interventions to promote health.

Personalized versus standard cognitive behavioral therapy for fear of cancer recurrence, depressive symptoms or cancer-related fatigue in cancer survivors: study protocol of a randomized controlled trial (MATCH-study)

Background

Fear of cancer recurrence, depressive symptoms, and cancer-related fatigue are prevalent symptoms among cancer survivors, adversely affecting patients’ quality of life and daily functioning. Effect sizes of interventions targeting these symptoms are mostly small to medium. Personalizing treatment is assumed to improve efficacy. However, thus far the empirical support for this approach is lacking. The aim of this study is to investigate if systematically personalized cognitive behavioral therapy is more efficacious than standard cognitive behavioral therapy in cancer survivors with moderate to severe fear of cancer recurrence, depressive symptoms, and/or cancer-related fatigue.

Methods

The study is designed as a non-blinded, multicenter randomized controlled trial with two treatment arms (ratio 1:1): (a) systematically personalized cognitive behavioral therapy and (b) standard cognitive behavioral therapy. In the standard treatment arm, patients receive an evidence-based diagnosis-specific treatment protocol for fear of cancer recurrence, depressive symptoms, or cancer-related fatigue. In the second arm, treatment is personalized on four dimensions: (a) the allocation of treatment modules based on ecological momentary assessments, (b) treatment delivery, (c) patients’ needs regarding the symptom for which they want to receive treatment, and (d) treatment duration. In total, 190 cancer survivors who experience one or more of the targeted symptoms and ended their medical treatment with curative intent at least 6 months to a maximum of 5 years ago will be included. Primary outcome is limitations in daily functioning. Secondary outcomes are level of fear of cancer recurrence, depressive symptoms, fatigue severity, quality of life, goal attainment, therapist time, and drop-out rates. Participants are assessed at baseline (T0), and after 6 months (T1) and 12 months (T2).

Discussion

To our knowledge, this is the first randomized controlled trial comparing the efficacy of personalized cognitive behavioral therapy to standard cognitive behavioral therapy in cancer survivors. The study has several innovative characteristics, among which is the personalization of interventions on several dimensions. If proven effective, the results of this study provide a first step in developing an evidence-based framework for personalizing therapies in a systematic and replicable way.

Effects of tandem cognitive behavioral therapy and healthy lifestyle interventions on health-related outcomes in cancer survivors: a systematic review

Purpose

Healthy lifestyle (HL) behaviors and cognitive behavioral therapy (CBT) have been individually shown to improve adverse effects of cancer treatment. Little is known about how such programs in tandem affect health-related outcomes. This review evaluates extant literature on tandem CBT/HL interventions on health-related outcomes in cancer survivors.

Methods

A comprehensive search of PubMed, PsychINFO, CINAHL, and Embase databases revealed numerous studies involving CBT and HL tandem interventions in cancer survivors in the last 20 years. Studies meeting the inclusion criteria were examined and assessed by the authors.

Results

The 36 studies included 5199 participants. Interventions involved the use of CBT in combination with a HL condition (stress reduction, increasing physical activity, etc.). These tandem conditions were compared against no intervention, usual care, and/or CBT alone or HL alone. Interventions were delivered by a variety of interventionists, and over different durations. The most common HL target outcomes were stress, and insomnia. Most studies (31 of 36) reported a reduction in adverse treatment and/or cancer-related effects.

Conclusion

Findings were biased with the overrepresentation of breast cancer survivors, and underrepresentation of minority groups, and those with advanced cancer. Thus, this review highlights the need for further research to test tandem interventions against CBT alone and HL alone, and toward identifying the most efficacious interventions for dissemination and implementation across diverse groups of cancer survivors.

Implications for cancer survivors

Tandem CBT/HL interventions can improve health-related outcomes for cancer survivors when compared to usual care, but there is a paucity of knowledge to suggest differential outcomes when compared to CBT or HL alone.

Personalizing cognitive behavioral therapy for cancer-related fatigue using ecological momentary assessments followed by automated individual time series analyses: A case report series

INTRODUCTION

A common approach to personalizing psychological interventions is the allocation of treatment modules to individual patients based on cut-off scores on questionnaires, which are mostly based on group studies. However, this way, intraindividual variation and temporal dynamics are not taken into account. Automated individual time series analyses are a possible solution, since these can identify the factors influencing the targeted symptom in a specific individual, and associated modules can be allocated accordingly. The aim of this study was to illustrate how automated individual time series analyses can be applied to personalize cognitive behavioral therapy for cancer-related fatigue in cancer survivors and how this procedure differs from allocating modules based on questionnaires.

METHODS

This study was a case report series (n = 3). Patients completed ecological momentary assessments at the start of therapy, and after three treatment modules (approximately 14 weeks). Assessments were analyzed with AutoVAR, an R package that automates the process of finding optimal vector autoregressive models. The results informed the treatment plan.

RESULTS

Three cases were described. From the ecological momentary assessments and automated time series analyses three individual treatment plans were constructed, in which the most important predictor for cancer-related fatigue was treated first. For two patients, this led to the treatment ending after the follow-up ecological momentary assessments. One patient continued treatment until six months, the standard treatment time in regular treatment. All three treatment plans differed from the treatment plans informed by questionnaire scores.

DISCUSSION

This study is one of the first to apply time series analyses in systematically personalizing psychological treatment. An important strength of this approach is that it can be used for every modular cognitive behavioral intervention where each treatment module addresses specific maintaining factors. Whether or not personalized CBT is more efficacious than standard, non-personalized CBT remains to be determined in controlled studies comparing it to usual care.

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.

Efficacy of Mindfulness-Based Cognitive Therapy and Cognitive Behavioral Therapy for Anxiety, Depression, and Fatigue in Cancer Patients: A Randomized Clinical Trial

Objective: Cancer is associated with some psychological problems that play an important role in the severity and continuity of cancer. Cancer may lead to maladaptive psychological reactions such as anxiety, depression, and fatigue. Depression and anxiety are highly prevalent in cancer patients. This study aimed to compare the efficacy of mindfulness-based cognitive therapy (MBCT) and cognitive behavioral therapy (CBT) for anxiety, depression, and fatigue in cancer patients.

Method: The present study was a randomized clinical trial (RCT). Of the 100 patients diagnosed with cancer, 60 patients were eligible to participate in this study according to the inclusion / exclusion criteria. They were randomly assigned into 3 groups: MBCT, CBT, and wait-list group (WLG). Afterward, the experimental groups received 8 weekly treatment sessions. All the participants fulfilled the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Cancer-Related Fatigue Scale (CFS) before and after the intervention. Data were analyzed using SPSS-16 software by Analysis of Covariance (ANCOVA).

Results: The results indicated a significant reduction in depression, anxiety, and fatigue scores in CBT and MBCT groups. There was a significant difference between both treatment groups with WLG in the anxiety and depression, but no significant difference was found between MBCT and CBT groups. Additionally, there was only a significant difference between the CBT group and WLG in terms of fatigue (P = 0.01).

Conclusion: CBT and MBCT performed equally well in decreasing anxiety and depression in cancer patients, and they were significantly better than WLG. It seems that MBCT is a good alternative to CBT for decreasing emotional symptoms in cancer patients. As a result, CBT and MBCT could be considered a good addition to pharmacological treatment of cancer patients with comorbid psychological symptoms. However, CBT was preferable to MBCT in decreasing fatigue.

The study was registered at the irct.ir database under registration number IRCT20180503039509N1.

Potential mechanisms of the fatigue-reducing effect of cognitive-behavioral therapy in cancer survivors: Three randomized controlled trials

OBJECTIVE

Fatigue is a common symptom among cancer survivors that can be successfully treated with cognitive-behavioral therapy (CBT). Insights into the working mechanisms of CBT are currently limited. The aim of this study was to investigate whether improvements in targeted cognitive-behavioral variables and reduced depressive symptoms mediate the fatigue-reducing effect of CBT.

METHODS

We pooled data from three randomized controlled trials that tested the efficacy of CBT to reduce severe fatigue. In all three trials, fatigue severity (checklist individual strength) decreased significantly following CBT. Assessments were conducted pre-treatment and 6 months later. Classical mediation analysis testing a pre-specified model was conducted and its results compared to those of causal discovery, an explorative data-driven approach testing all possible causal associations and retaining the most likely model.

RESULTS

Data from 250 cancer survivors (n = 129 CBT, n = 121 waitlist) were analyzed. Classical mediation analysis suggests that increased self-efficacy and decreased fatigue catastrophizing, focusing on symptoms, perceived problems with activity and depressive symptoms mediate the reduction of fatigue brought by CBT. Conversely, causal discovery and post-hoc analyses indicate that fatigue acts as mediator, not outcome, of changes in cognitions, sleep disturbance and depressive symptoms.

CONCLUSIONS

Cognitions, sleep disturbance and depressive symptoms improve during CBT. When assessed pre- and post-treatment, fatigue acts as a mediator, not outcome, of these improvements. It seems likely that the working mechanism of CBT is not a one-way causal effect but a dynamic reciprocal process. Trials integrating intermittent assessments are needed to shed light on these mechanisms and inform optimization of CBT.

Congruence and trajectories of device-measured and self-reported physical activity during therapy for early breast cancer

Purpose

This study examines congruence between self-reported and device-measured physical activity data in women with early breast cancer and compares trajectories under different treatments.

Methods

Women with non-metastatic breast cancer were recruited before primary therapy. In four weeks distributed over six months after treatment start, patients reported time spent on work, transport, chores and sports via diary and wore Garmin^® vivofit 3 accelerometers to assess steps taken. Associations between these measures and agreement regarding guideline adherence were tested with Spearman’s Correlation Coefficient and Weighted Kappa statistic. Effects of time and treatment were evaluated using mixed analyses of variance.

Results

Ninety-nine participants (median age = 50) were treated with adjuvant (N= 23), neoadjuvant (N= 21) or without chemotherapy (N= 55). Coherence between self-report and device data was strong (r = 0.566). Agreement about reaching recommendations was only “fair” (kappa coefficient = 0.321 and 0.249, resp.). Neither treatment or week nor their interaction had effects on step counts (all p > 0.05). Self-reported activity time was lower for patients with chemotherapy than for those without (adjuvant: ∆ = 69min, p= 0.006, neoadjuvant: ∆ = 45min, p= 0.038) and lower in week 18 than in week 3 (∆ = 43min, p= 0.010).

Conclusion

Results show that consumer-grade activity monitors and self-reports correlate but show different perspectives on physical activity in breast cancer patients. In general, patients perceive some decline regardless of primary treatment regimen. Those affected should be offered assistance to gain the benefits of activity. Accelerometers may help professionals to identify these individuals and patients to verify appraisal of their activity levels.

The effect of behaviour change interventions on changes in physical activity and anthropometrics in ambulatory hospital settings: a systematic review and meta-analysis

Background

The aim of this systematic review and meta-analysis was to investigate whether behaviour change interventions promote changes in physical activity and anthropometrics (body mass, body mass index and waist circumference) in ambulatory hospital populations.

Methods

Randomised controlled trials were collected from five bibliographic databases (MEDLINE, Embase, CINAHL, The Cochrane Central Register of Controlled Trials (CENTRAL) and PsycINFO). Meta-analyses were conducted using change scores from baseline to determine mean differences (MD), standardised mean differences (SMD) and 95% confidence intervals (95% CI). The Grades of Recommendation, Assessment, Development and Evaluation approach was used to evaluate the quality of the evidence.

Results

A total of 29 studies met the eligibility criteria and 21 were included in meta-analyses. Behaviour change interventions significantly increased physical activity (SMD: 1.30; 95% CI: 0.53 to 2.07, p < 0.01), and resulted in significant reductions in body mass (MD: -2.74; 95% CI: − 4.42 to − 1.07, p < 0.01), body mass index (MD: -0.99; 95% CI: − 1.48 to − 0.50, p < 0.01) and waist circumference (MD: -2.21; 95% CI: − 4.01 to − 0.42, p = 0.02). The GRADE assessment indicated that the evidence is very uncertain about the effect of behaviour change interventions on changes in physical activity and anthropometrics in ambulatory hospital patients.

Conclusions

Behaviour change interventions initiated in the ambulatory hospital setting significantly increased physical activity and significantly reduced body mass, body mass index and waist circumference. Increased clarity in interventions definitions and assessments of treatment fidelity are factors that need attention in future research.

Cognitive behavioral therapy or graded exercise therapy compared with usual care for severe fatigue in patients with advanced cancer during treatment: a randomized controlled trial

BACKGROUND

Cancer-related fatigue remains a prevalent and burdensome symptom experienced by patients with advanced cancer. Our aim was to assess the effects of cognitive behavioral therapy (CBT) or graded exercise therapy (GET) on fatigue in patients with advanced cancer during treatment with palliative intent.

PATIENTS AND METHODS

A randomized controlled trial was conducted from 1 January 2013 to 1 September 2017. Adult patients with locally advanced or metastatic cancer who reported severe fatigue during treatment [Checklist Individual Strength, subscale fatigue severity (CIS-fatigue) ≥35] were accrued across nine centers in The Netherlands. Patients were randomly assigned to either 12 weeks of CBT or GET, or usual care (1 : 1: 1, computer-generated sequence). Primary outcome was CIS-fatigue at 14 weeks. Secondary outcomes included fatigue measured with the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ-C30), quality of life, emotional functioning, physical functioning, and functional impairments at baseline, 14, 18, and 26 weeks.

RESULTS

Among 134 participants randomized, the mean age was 63 (standard deviation 9) years and 77 (57%) were women. Common diagnoses included: breast (41%), colorectal (28%), and prostate cancer (17%). A total of 126 participants completed assessment at 14 weeks. Compared with usual care, CBT significantly reduced fatigue [difference -7.2, 97.5% confidence interval (CI) -12.7 to -1.7; P = 0.003, d = 0.7], whereas GET did not (-4.7, 97.5% CI -10.2 to 0.9; P = 0.057, d = 0.4). CBT significantly reduced EORTC-QLQ-C30 fatigue (-13.1, 95% CI -22.1 to -4.0; P = 0.005) and improved quality of life (10.2, 95% CI 2.4 to 17.9; P = 0.011) and physical functioning (7.1, 95% CI 0.5 to 13.7; P = 0.036) compared with usual care. Improvement in emotional functioning and decrease in functional impairments failed to reach significance. GET did not improve secondary outcomes compared with usual care.

CONCLUSIONS

Among advanced cancer patients with severe fatigue during treatment, a CBT intervention was more effective than usual care for reducing fatigue. Following GET, patients reported lower fatigue, but results were not significant, probably due to a smaller sample size and lower adherence than anticipated.

Moderators of the effect of psychosocial interventions on fatigue in women with breast cancer and men with prostate cancer: Individual patient data meta-analyses

OBJECTIVE

Psychosocial interventions can reduce cancer-related fatigue effectively. However, it is still unclear if intervention effects differ across subgroups of patients. These meta-analyses aimed at evaluating moderator effects of (a) sociodemographic characteristics, (b) clinical characteristics, (c) baseline levels of fatigue and other symptoms, and (d) intervention-related characteristics on the effect of psychosocial interventions on cancer-related fatigue in patients with non-metastatic breast and prostate cancer.

METHODS

Data were retrieved from the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) consortium. Potential moderators were studied with meta-analyses of pooled individual patient data from 14 randomized controlled trials through linear mixed-effects models with interaction tests. The analyses were conducted separately in patients with breast (n = 1091) and prostate cancer (n = 1008).

RESULTS

Statistically significant, small overall effects of psychosocial interventions on fatigue were found (breast cancer: β = -0.19 [95% confidence interval (95%CI) = -0.30; -0.08]; prostate cancer: β = -0.11 [95%CI = -0.21; -0.00]). In both patient groups, intervention effects did not differ significantly by sociodemographic or clinical characteristics, nor by baseline levels of fatigue or pain. For intervention-related moderators (only tested among women with breast cancer), statistically significant larger effects were found for cognitive behavioral therapy as intervention strategy (β = -0.27 [95%CI = -0.40; -0.15]), fatigue-specific interventions (β = -0.48 [95%CI = -0.79; -0.18]), and interventions that only targeted patients with clinically relevant fatigue (β = -0.85 [95%CI = -1.40; -0.30]).

CONCLUSIONS

Our findings did not provide evidence that any selected demographic or clinical characteristic, or baseline levels of fatigue or pain, moderated effects of psychosocial interventions on fatigue. A specific focus on decreasing fatigue seems beneficial for patients with breast cancer with clinically relevant fatigue.

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.

Cognitive Behavioral Therapy for Treatment-Related Fatigue in Chronic Myeloid Leukemia Patients on Tyrosine Kinase Inhibitors: A Mixed-Method Study

Treatment-related fatigue significantly limits quality of life among chronic myeloid leukemia (CML) patients receiving tyrosine kinase inhibitors (TKIs), yet no interventions to reduce this symptom have been studied. We examined preliminary feasibility and efficacy of cognitive behavioral therapy for TKI treatment-related fatigue in patients with CML. We used a mixed methods convergent design and collected quantitative data through randomized single-case experiments. We included CML patients receiving TKIs and reporting severe fatigue. Within each participant, we compared CBT to a no-treatment baseline period. Fatigue severity was measured weekly with the Checklist Individual Strength. Fatigue scores were subjected to visual analyses and randomization tests for single-case experimental designs. We conducted qualitative interviews after study participation and focused on feasibility and efficacy of CBT. Visual inspection of line graphs indicated downward trends in the expected direction for fatigue in two of the four participants. The test statistics showed a decrease in fatigue severity for all participants but randomization tests did not reach statistical significance (overall p = 0.18). Participants reported qualitative improvements in level of functioning and coping with fatigue. CBT was considered feasible and acceptable for severely fatigued CML patients. Our study provided preliminary evidence for the feasibility and acceptability of CBT for severely fatigued CML patients receiving targeted therapy. We recommend further efficacy testing of this promising intervention in a pilot randomized controlled trial.

Effects and moderators of coping skills training on symptoms of depression and anxiety in patients with cancer: Aggregate data and individual patient data meta-analyses

PURPOSE

This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects.

METHODS

Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs.

RESULTS

CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (p_interaction < 0.025), with the largest reductions in patients <50 years (β = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = -0.16,95%CI = -0.25;-0.07) and anxiety (β = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (p_interaction < 0.05).

CONCLUSIONS

CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

Patterns and predictors of cancer-related fatigue in ovarian and endometrial cancers: 1-year longitudinal study

BACKGROUND

Fatigue is a common and distressing symptom for patients with gynecologic cancers. Few studies have empirically examined whether it spontaneously resolves. This study was aimed at identifying longitudinal patterns of fatigue and predictors of clinically significant fatigue 1 year after treatment completion.

METHODS

This was a prospective cohort study of women with newly diagnosed ovarian (n = 81) or endometrial cancer (n = 181) that did not progress or recur within 1 year of treatment completion. Symptoms of fatigue, depression, and anxiety were assessed after surgery and 6 and 12 months after treatment completion with the Fatigue Assessment Scale and the Hospital Anxiety and Depression Scale. Patients' fatigue scores over time were classified (scores of 22-50, clinically significant; scores of 10-21, not clinically significant). Logistic regression models were fit to examine associations between fatigue and patient characteristics.

RESULTS

Among 262 participants, 48% reported clinically significant fatigue after surgery. One year later, 39% reported fatigue. There were 6 patterns over time: always low (37%), always high (25%), high then resolves (18%), new onset (10%), fluctuating (6%), and incidental (5%). Patients with fatigue after surgery were more likely to report fatigue at 12 months in comparison with others (odds ratio [OR], 6.08; 95% confidence interval [CI], 2.82-13.11; P < .001). Patients with depressive symptoms also had higher odds of fatigue (OR, 3.36; 95% CI, 1.08-10.65; P = .039), although only one-third of fatigued patients reported depressive symptoms.

CONCLUSION

Nearly half of women with gynecologic cancers had clinically significant fatigue after surgery, whereas 44% and 39% had fatigue 6 months and 1 year later; this suggests that spontaneous regression of symptoms is relatively rare. Women who reported fatigue, depressive symptoms, or 2 or more medical comorbidities had higher odds of reporting fatigue 1 year later. Future studies should test scalable interventions to improve fatigue in women with gynecologic cancers.

Targeting Exercise Interventions to Patients With Cancer in Need: An Individual Patient Data Meta-Analysis

Background

Exercise effects in cancer patients often appear modest, possibly because interventions rarely target patients most in need. This study investigated the moderator effects of baseline values on the exercise outcomes of fatigue, aerobic fitness, muscle strength, quality of life (QoL), and self-reported physical function (PF) in cancer patients during and post-treatment.

Methods

Individual patient data from 34 randomized exercise trials (n = 4519) were pooled. Linear mixed-effect models were used to study moderator effects of baseline values on exercise intervention outcomes and to determine whether these moderator effects differed by intervention timing (during vs post-treatment). All statistical tests were two-sided.

Results

Moderator effects of baseline fatigue and PF were consistent across intervention timing, with greater effects in patients with worse fatigue (Pinteraction = .05) and worse PF (Pinteraction = .003). Moderator effects of baseline aerobic fitness, muscle strength, and QoL differed by intervention timing. During treatment, effects on aerobic fitness were greater for patients with better baseline aerobic fitness (Pinteraction = .002). Post-treatment, effects on upper (Pinteraction < .001) and lower (Pinteraction = .01) body muscle strength and QoL (Pinteraction < .001) were greater in patients with worse baseline values.

Conclusion

Although exercise should be encouraged for most cancer patients during and post-treatments, targeting specific subgroups may be especially beneficial and cost effective. For fatigue and PF, interventions during and post-treatment should target patients with high fatigue and low PF. During treatment, patients experience benefit for muscle strength and QoL regardless of baseline values; however, only patients with low baseline values benefit post-treatment. For aerobic fitness, patients with low baseline values do not appear to benefit from exercise during treatment.

Pilot randomized controlled trial of a symptom cluster intervention in advanced cancer

OBJECTIVE

This study evaluated a three-session acceptance-based cognitive behavioral -acceptance and commitment therapy (CBT-ACT) intervention targeting a common symptom cluster in advanced cancer-worry-insomnia-depression-fatigue.

METHODS

Twenty-eight patients with advanced cancer were randomly assigned to the CBT-ACT intervention or waitlist. At preintervention, participants completed a psychodiagnostic interview, standardized questionnaires, and a sleep diary. Intervention and waitlist groups were reassessed after 6 weeks, at which point the waitlist group completed the intervention.

RESULTS

Participants receiving the intervention demonstrated improved sleep efficiency (P = 0.0062, d = 1.08), sleep latency (P = 0.028, d = -0.86), insomnia severity (P = 0.0047, d = -1.18), and worry (P = 0.026, d = -0.89) compared with waitlist controls. They also demonstrated a 7-point reduction on depression (P = 0.03, d = -0.88), reduced hyperarousal (P = 0.005, d = -1.51), and a decrease in distress (P = 0.032, d = -0.83). Effects were maintained for the whole sample in sensitivity analyses. Effects on uncertainty intolerance approached significance (P = 0.058). No effect was found on fatigue.

CONCLUSIONS

The CBT-ACT group performed significantly better than the waitlist control group. CBT-ACT yielded strong effects for worry, sleep, depression, emotional distress, total distress, and hyperarousal. Future studies will enhance the fatigue and uncertainty tolerance components of the intervention.

Effects and moderators of psychosocial interventions on quality of life, and emotional and social function in patients with cancer: An individual patient data meta-analysis of 22 RCTs

Objective

This individual patient data (IPD) meta‐analysis aimed to evaluate the effects of psychosocial interventions (PSI) on quality of life (QoL), emotional function (EF), and social function (SF) in patients with cancer, and to study moderator effects of demographic, clinical, personal, and intervention‐related characteristics.

Methods

Relevant studies were identified via literature searches in 4 databases. We pooled IPD from 22 (n = 4217) of 61 eligible randomized controlled trials. Linear mixed‐effect model analyses were used to study intervention effects on the post‐intervention values of QoL, EF, and SF (z‐scores), adjusting for baseline values, age, and cancer type. We studied moderator effects by testing interactions with the intervention for demographic, clinical, personal, and intervention‐related characteristics, and conducted subsequent stratified analyses for significant moderator variables.Results: PSI significantly improved QoL (β = 0.14,95%CI = 0.06;0.21), EF (β = 0.13,95%CI = 0.05;0.20), and SF (β = 0.10,95%CI = 0.03;0.18). Significant differences in effects of different types of PSI were found, with largest effects of psychotherapy. The effects of coping skills training were moderated by age, treatment type, and targeted interventions. Effects of psychotherapy on EF may be moderated by cancer type, but these analyses were based on 2 randomized controlled trials with small sample sizes of some cancer types.

Conclusions

PSI significantly improved QoL, EF, and SF, with small overall effects. However, the effects differed by several demographic, clinical, personal, and intervention‐related characteristics. Our study highlights the beneficial effects of coping skills training in patients treated with chemotherapy, the importance of targeted interventions, and the need of developing interventions tailored to the specific needs of elderly patients.

Which exercise prescriptions improve quality of life and physical function in patients with cancer during and following treatment? A systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

Certain exercise prescriptions for patients with cancer may improve self-reported quality of life (QoL) and self-reported physical function (PF). We investigated the effects of exercise on QoL and PF in patients with cancer and studied differences in effects between different intervention-related and exercise-related characteristics.

DESIGN

We searched four electronic databases to identify randomised controlled trials investigating exercise effects on QoL and PF in patients with cancer. Pooled effects (Hedges' g) were calculated using Comprehensive Meta-Analysis software. Subgroup analyses were conducted based on intervention dimensions, including timing, duration and delivery mode, and exercise dimensions, including frequency, intensity, type and time (FITT factors).

RESULTS

We included 74 exercise arms. Patients who were randomised to exercise interventions had significantly improved QoL (g=0.15, 95% CI (0.10 to 0.20), n=67 exercise arms) and PF (g=0.21, 95% CI (0.15 to 0.27), n=59 exercise arms) compared with patients in control groups. We found a significant between-group difference for exercise delivery mode, with significant beneficial effects for supervised exercise interventions (g=0.20, 95% CI (0.14 to 0.26) for QoL and g=0.27, 95% CI (0.20 to 0.33) for PF), but not for unsupervised interventions (g=0.04, 95% CI (-0.06 to 0.13) for QoL and g=0.09, 95% CI (-0.01 to 0.19) for PF). No statistically significant differences in intervention effects were found for variations in intervention timing, duration or exercise FITT factors. Unsupervised exercise with higher weekly energy expenditure was more effective than unsupervised exercise with lower energy expenditure (z=2.34, p=0.02).

CONCLUSIONS

Exercise interventions, especially when supervised, have statistically significant and small clinical benefit on self-reported QoL and PF in patients with cancer. Unsupervised exercise intervention effects on PF were larger when prescribed at a higher weekly energy expenditure.

The assessment of fatigue: Psychometric qualities and norms for the Checklist individual strength

OBJECTIVE

The Checklist Individual Strength (CIS) measures four dimensions of fatigue: Fatigue severity, concentration problems, reduced motivation and activity. On the fatigue severity subscale, a cut-off score of 35 is used. This study 1) investigated the psychometric qualities of the CIS; 2) validated the cut-off score for severe fatigue and 3) provided norms.

METHODS

Representatives of the Dutch general population (n=2288) completed the CIS. The factor structure was investigated using an exploratory factor analysis. Internal consistency and test-retest reliability were determined. Concurrent validity was assessed in two additional samples by correlating the CIS with other fatigue scales (Chalder Fatigue Questionnaire, MOS Short form-36 Vitality subscale, EORTC QLQ-C30 fatigue subscale). To validate the fatigue severity cut-off score, a Receiver Operating Characteristics analysis was performed with patients referred to a chronic fatigue treatment centre (n=5243) and a healthy group (n=1906). Norm scores for CIS subscales were calculated for the general population, patients with chronic fatigue syndrome (CFS; n=1407) and eight groups with other medical conditions (n=1411).

RESULTS

The original four-factor structure of the CIS was replicated. Internal consistency (α=0.84-0.95) and test-retest reliability (r=0.74-0.86) of the subscales were high. Correlations with other fatigue scales were moderate to high. The 35 points cut-off score for severe fatigue is appropriate, but, given the 17% false positive rate, should be adjusted to 40 for research in CFS.

CONCLUSION

The CIS is a valid and reliable tool for the assessment of fatigue, with a validated cut-off score for severe fatigue that can be used in clinical practice.

Prevalence and impact of severe fatigue in adolescent and young adult cancer patients in comparison with population-based controls

Purpose

The current study determined the prevalence of severe fatigue in adolescent and young adult (AYA) cancer patients (aged 18–35 years at diagnosis) consulting a multidisciplinary AYA team in comparison with gender- and age-matched population-based controls. In addition, impact of severe fatigue on quality of life and correlates of fatigue severity were examined.

Methods

AYAs with cancer (n = 83) completed questionnaires including the Checklist Individual Strength (CIS-fatigue), Quality of Life (QoL)-Cancer Survivor, Hospital Anxiety and Depression Scale (reflecting psychological distress), and the Cancer Worry Scale (reflecting fear of cancer recurrence or progression).

Results

The vast majority of participants had been treated with chemotherapy (87%) and had no active treatment at the time of participation (73.5%). Prevalence of severe fatigue (CIS-fatigue score ≥35) in AYAs with cancer (48%, n = 40/83) was significantly higher in comparison with matched population-based controls (20%, n = 49/249; p < .001). Severely fatigued AYAs with cancer reported lower QoL compared to non-severely fatigued AYAs with cancer (p < .05). Female gender, being unemployed, higher disease stage (III–IV) at diagnosis, receiving active treatment at the time of study participation, being treated with palliative intent, having had radiotherapy, higher fear of recurrence or progression, and higher psychological distress were significantly correlated with fatigue severity (p < .05).

Conclusions

Severe fatigue based on a validated cut-off score was highly prevalent in this group of AYAs with cancer. QoL is significantly affected by severe fatigue, stressing the importance of detection and management of this symptom in those patients affected by a life-changing diagnosis of cancer in late adolescence or young adulthood.

Study protocol of the TIRED study: a randomised controlled trial comparing either graded exercise therapy for severe fatigue or cognitive behaviour therapy with usual care in patients with incurable cancer

BACKGROUND

Fatigue is a common and debilitating symptom for patients with incurable cancer receiving systemic treatment with palliative intent. There is evidence that non-pharmacological interventions such as graded exercise therapy (GET) or cognitive behaviour therapy (CBT) reduce cancer-related fatigue in disease-free cancer patients and in patients receiving treatment with curative intent. These interventions may also result in a reduction of fatigue in patients receiving treatment with palliative intent, by improving physical fitness (GET) or changing fatigue-related cognitions and behaviour (CBT). The primary aim of our study is to assess the efficacy of GET or CBT compared to usual care (UC) in reducing fatigue in patients with incurable cancer.

METHODS

The TIRED study is a multicentre three-armed randomised controlled trial (RCT) for incurable cancer patients receiving systemic treatment with palliative intent. Participants will be randomised to GET, CBT, or UC. In addition to UC, the GET group will participate in a 12-week supervised exercise programme. The CBT group will receive a 12-week CBT intervention in addition to UC. Primary and secondary outcome measures will be assessed at baseline, post-intervention (14 weeks), and at follow-up assessments (18 and 26 weeks post-randomisation). The primary outcome measure is fatigue severity (Checklist Individual Strength subscale fatigue severity). Secondary outcome measures are fatigue (EORTC-QLQ-C30 subscale fatigue), functional impairments (Sickness Impact Profile total score, EORTC-QLQ-C30 subscale emotional functioning, subscale physical functioning) and quality of life (EORTC-QLQ-C30 subscale QoL). Outcomes at 14 weeks (primary endpoint) of either treatment arm will be compared to those of UC participants. In addition, outcomes at 18 and 26 weeks (follow-up assessments) of either treatment arm will be compared to those of UC participants.

DISCUSSION

To our knowledge, the TIRED study is the first RCT investigating the efficacy of GET and CBT on reducing fatigue during treatment with palliative intent in incurable cancer patients. The results of this study will provide information about the possibility and efficacy of GET and CBT for severely fatigued incurable cancer patients.

Fatigue in Advanced Cancer Patients: Congruence Between Patients and Their Informal Caregivers About Patients' Fatigue Severity During Cancer Treatment With Palliative Intent and Predictors of Agreement

CONTEXT

Informal caregivers (ICs) are increasingly involved in the monitoring of symptoms during advanced cancer patients' treatment with palliative intent. A common but subjective symptom during this extended treatment phase is fatigue.

OBJECTIVES

This exploratory longitudinal study aimed to determine agreement between patients and ICs about patients' fatigue severity. In addition, predictors of agreement over time were studied.

METHODS

A sample of 107 patients with advanced cancer (life expectancy ≥ six months) and their ICs completed the subscale fatigue severity of the Checklist Individual Strength based on the patient's status at baseline and six months later. This eight-item subscale has a validated cutoff to determine the presence of clinically relevant levels of fatigue. ICs' own fatigue severity, strain, self-esteem, and relationship satisfaction were examined as predictors of agreement.

RESULTS

A total of 107 dyads completed measures at baseline and 69 dyads six months later. At baseline, ICs' significantly overestimated patients' fatigue severity (P < 0.001) with a moderate amount of bias (Cohen's d = 0.48). In 81 of the 107 dyads (76%), there was congruence about the presence or absence of severe fatigue. On a group level, congruence did not significantly change over time. On a dyad level, there was a tendency to either remain congruent or reach congruence. Next to baseline congruence, ICs' fatigue severity and strain predicted ICs' fatigue ratings (R(2) = 0.22).

CONCLUSION

Most ICs accurately predict presence or absence of clinically relevant levels of patients' fatigue. ICs' own fatigue severity and strain should be taken into account as they influence agreement.

Prevalence, Impact, and Correlates of Severe Fatigue in Patients With Gastrointestinal Stromal Tumors

CONTEXT

The introduction of the tyrosine kinase inhibitor (TKI) imatinib in the treatment of gastrointestinal stromal tumor (GIST) in 2000 was the start of a new era of targeted treatment. Since then, the median survival of patients with GIST has substantially increased. Prolonged survival and chronic TKI use are associated with treatment-induced symptoms, such as fatigue, which can compromise quality of life (QoL).

OBJECTIVES

This study determined the prevalence of severe fatigue in GIST patients compared to matched healthy controls, the impact of fatigue on daily life, and associations between fatigue and current TKI use.

METHODS

One hundred nineteen patients treated with surgery and/or a TKI for GIST were asked to participate. Participants completed questionnaires including the Checklist Individual Strength-Fatigue Severity scale (CIS-fatigue), Short-Form 36-Item Health Survey, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, Fatigue Catastrophizing Scale, Self-Efficacy Scale, and the Hospital Anxiety and Depression Scale.

RESULTS

Eighty-nine GIST patients (75%) completed questionnaires, 61 patients (69%) were on a TKI. Prevalence of severe fatigue measured with CIS-fatigue was significantly higher in GIST patients (30%) than in 234 matched healthy controls (15%). The prevalence of severe fatigue did not differ significantly between patients receiving treatment with curative (29%) or palliative intent (36%). Severely fatigued patients reported lower QoL and more impairment on all functional domains. TKI use, more psychological distress, and lower physical functioning were associated with fatigue.

CONCLUSION

Severe fatigue occurs in 30% of GIST patients and in 33% of GIST patients on a TKI. The fatigue is disabling and is not only associated with current TKI use but also with psychological distress and physical functioning. GIST patients should be informed about these associated factors of fatigue that deserve appropriate management.

Interventions for cancer-related fatigue: a scoping review

Cancer-related fatigue (CRF) is common and can be distressing for some survivors. There is increasing interest in measuring levels of CRF, highlighting its impact on quality of life. This review describes the nature and scope of evidence relating to interventions for CRF. Scoping review methodology was used to identify studies, extract data, collate and summarise results. Data were collated according to cancer tumour streams, stage of illness and the types of trial interventions. A total of 447 trials and 37 systematic reviews met the inclusion criteria. Nine papers reported longitudinal results. Populations studied were predominantly of mixed cancer diagnoses and breast cancer. The most frequent interventions were exercise, pharmacological, psycho-education and mind-body interventions. Fatigue was identified as a primary outcome measure (OM) in 58% of studies, with 58 different fatigue measures reported. Emerging evidence exists for the effectiveness of fatigue interventions for some cancer types. More research on interventions with participants with the same cancer type and illness phase is needed. Measurement of severity and impact of CRF using fewer, robust OMs will permit comparisons across studies.

Exercise improves quality of life in patients with cancer: a systematic review and meta-analysis of randomised controlled trials

PURPOSE

Exercise may be associated with increased health-related quality of life (QoL) in patients with cancer, but it is not prescribed as standard care during or after cancer treatment. We systematically reviewed the methodological quality of, and summarised the evidence from, randomised controlled trials (RCTs). A meta-analysis was performed to examine the effectiveness of exercise in improving the QoL in patients with cancer, during and after medical treatment.

METHODS

RCTs that met the PICO (Patient Intervention Control Outcome) format were included in this study. 16 RCTs were identified through a search of Embase, Medline (OvidSP) and the Cochrane Library. These trials were reviewed for substantive results and the methodological quality was assessed using the Delphi criteria list.

RESULTS

Exercise interventions differed widely in content, frequency, duration and intensity. Based on the meta-analysis, exercise improved QoL significantly in patients with cancer as compared to usual care (mean difference 5.55, 95% CI (3.19 to 7.90), p<0.001). Other outcomes closely related to QoL, such as fatigue and physical functioning, also improved.

CONCLUSIONS

Exercise has a direct positive impact on QoL in patients with cancer, during and following medical intervention. Exercise is a clinically relevant treatment and should be an adjunct to disease therapy in oncology.

Cancer rehabilitation: outcome evaluation of a strengthening and conditioning program

BACKGROUND

Cancer treatments can lead to detriments in patients' health and declines in quality of life (QOL). Cancer rehabilitation programs may improve functional status, symptom control, and QOL.

OBJECTIVE

The objective of this study was to determine if an outpatient, physical therapy-supervised Cancer Rehabilitation Strengthening and Conditioning (CRSC) program improved patients' conditioning level, functional status, QOL, and symptoms.

METHODS

This was a prospective study of oncology patients participating in CRSC program. Measurements included conditioning level (6-minute walk test [SMWT], metabolic equivalent level, grip strength), functional status (Physical Component Summary of Short Form 36), QOL (Mental Component Summary of Short Form 36), and symptoms (M. D. Anderson Symptom Inventory). Paired t tests were conducted to determine significant changes between pre- and post-CRSC program measures, and regression methods identified predictors of change from baseline.

RESULTS

One hundred fifteen patients with cancer were enrolled in the study; 75 patients completed pre- and post-CRSC program measures. Significant improvements were noted in SMWT by 186.4 ft, SMWT speed by 0.35 mph, treadmill time (3.5 minutes longer), metabolic equivalent level (by 0.87 units), QOL, symptom severity, symptom interference with daily life, fatigue, shortness of breath, and sadness.

CONCLUSIONS

In a pretest-posttest design, significant improvements were noted in conditioning level, functional status, QOL, and symptoms. Greater improvements were noted in participants who were most deconditioned at baseline.

IMPLICATIONS FOR PRACTICE

Further research should be conducted to provide additional support for CRSC programs. Cancer rehabilitation strengthening and condition programs may benefit patients across the continuum of care, including deconditioned patients.

Putting evidence into practice: an update of evidence-based interventions for cancer-related fatigue during and following treatment

Cancer-related fatigue (CRF) has deleterious effects on physical, social, cognitive, and vocational functioning, and causes emotional and spiritual distress for patients and their families; however, it remains under-recognized and undertreated. This article critically reviews and integrates the available empirical evidence supporting the efficacy of pharmacologic and nonpharmacologic treatment approaches to CRF, highlighting new evidence since 2007 and 2009 Putting Evidence Into Practice publications. Interventions that are recommended for practice or likely to be effective in improving fatigue outcomes include exercise; screening for treatable risk factors; management of concurrent symptoms; yoga; structured rehabilitation; Wisconsin ginseng; cognitive-behavioral therapies for insomnia, pain, and depression; mindfulness-based stress reduction; and psychoeducational interventions such as anticipatory guidance, psychosocial support, and energy conservation and activity management. This information can be applied to improve the management of CRF, inform health policy and program development, shape the design of clinical trials of new therapies for CRF, and drive basic and translational research.

Screening, evaluation, and management of cancer-related fatigue: Ready for implementation to practice?

Answer questions and earn CME/CNE Evidence regarding cancer-related fatigue (fatigue) has accumulated sufficiently such that recommendations for screening, evaluation, and/or management have been released recently by 4 leading cancer organizations. These evidence-based fatigue recommendations are available for clinicians, and some have patient versions; but barriers at the patient, clinician, and system levels hinder dissemination and implementation into practice. The underlying biologic mechanisms for this debilitating symptom have not been elucidated completely, hindering the development of mechanistically driven interventions. However, significant progress has been made toward methods for screening and comprehensively evaluating fatigue and other common symptoms using reliable and valid self-report measures. Limited data exist to support the use of any pharmacologic agent; however, several nonpharmacologic interventions have been shown to be effective in reducing fatigue in adults. Never before have evidence-based recommendations for fatigue management been disseminated by 4 premier cancer organizations (the National Comprehensive Cancer, the Oncology Nursing Society, the Canadian Partnership Against Cancer/Canadian Association of Psychosocial Oncology, and the American Society of Clinical Oncology). Clinicians may ask: Are we ready for implementation into practice? The reply: A variety of approaches to screening, evaluation, and management are ready for implementation. To reduce fatigue severity and distress and its impact on functioning, intensified collaborations and close partnerships between clinicians and researchers are needed, with an emphasis on system-wide efforts to disseminate and implement these evidence-based recommendations.

Relationship between patterns of daily physical activity and fatigue in cancer survivors

PURPOSE

This study investigated: (1) physical activity behaviour of cancer survivors throughout the day, (2) the relationship between objective and subjective measures of physical activity, and (3) the relationship between daily physical activity and fatigue.

METHOD

Physical activity was measured objectively using 3D-accelerometry (expressed in counts per minute (cpm)), and subjectively using a Visual Analogue Scale (VAS; 0-10) implemented on a smartphone in 18 cancer survivors (6 male; age 55.7 ± 10.2 yrs; free from cancer, last treatment ≥three months previously), and matched controls. Fatigue was scored thrice daily on a smartphone (0-10 VAS).

RESULTS

Mean daily physical activity of cancer survivors did not deviate from controls (1108 ± 287 cpm versus 1223 ± 371 cpm, p = .305). However, in cancer survivors physical activity significantly decreased from morning to evening (p < .01) and increased levels of fatigue throughout the day were reported (p < .01). Furthermore, a positive correlation was found between levels of fatigue and the magnitude of the decline in physical activity from afternoon to evening (p < .05). Objective and subjective measured physical activity showed low correlations.

CONCLUSIONS

This study demonstrated imbalanced activity patterns in cancer survivors. Also, the more a survivor felt fatigued, the greater the decline in activity behaviour throughout the day. The low correlation between objective and subjective physical activity suggests low awareness in cancer survivors about their daily physical activity performed. Ambulatory monitoring provides new insights in both patterns of physical activity and fatigue, which might be a valuable tool to provide activity management more efficiently during treatment of fatigue.

Physical Activity of Patients With Chronic Pain Receiving Acceptance and Commitment Therapy or Cognitive Behavioural Therapy

Physical activity is positively related to various indices of quality of life and is found to reduce symptoms in individuals with chronic pain. This manuscript presents findings from a post hoc analysis investigating whether treatment-related improvements from psychological treatment for chronic pain are mediated by changes in physical activity (PA). Secondary analyses sought to determine predictor variables of PA in patients with chronic pain and to determine the relationship between objective and self-report measurements of PA. The effect of psychological treatment on physical activity was assessed using accelerometers in a sample of participants with chronic pain in a randomised controlled trial comparing 8 weeks of acceptance and commitment therapy (ACT) to cognitive behavioural therapy (CBT). Participants wore actigraph accelerometers for 7 consecutive days at baseline, post-treatment, and at 6-month follow-up. Hierarchical linear modelling analyses found that the variance in physical activity was not significantly predicted by time (b = 104.67, p = .92) or treatment modality (b = −1659.34, p = .57). Women had greater increases in physical activity than did men (b = 6804.08, p = .02). Current ‘gold standard’ psychological treatments for chronic pain were not found to significantly increase physical activity, an important outcome to target in the treatment of physical and mental health. These results suggest that tailored interventions with greater emphasis on exercise may complement psychological treatment for chronic pain. In particular, gender-tailored interventions may capitalise on physical activity differences found between men and women.

Impact of therapy and disease-related symptoms on health-related quality of life in patients with follicular lymphoma: results of the population-based PHAROS-registry

OBJECTIVES

The increasing number of longer living patients with follicular lymphoma (FL) and serious side effects of treatment urged us to study the health-related quality of life (HRQoL) and persistent (treatment-related) symptoms in unselected patients after different treatment modalities and compare HRQoL of patients with a normative population.

METHODS

The population-based Eindhoven Cancer Registry was used to select patients diagnosed with FL during 2004-2010. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) was completed twice, with a 1-yr interval. This questionnaire was also completed by an age- and sex-matched normative population (N = 580). Detailed data on treatment were extracted from the cancer registry and Population-based HAematological Registry for Observational Studies (PHAROS).

RESULTS

Of the 181 patients who were invited, 148 responded (82%, T1). Patients treated with immunochemotherapy reported clinically relevant higher mean fatigue scores than those who underwent radiotherapy (P = 0.02). No differences were observed on the other HRQoL scales between treatment groups. Mean HRQoL scores were worse for FL patients treated with immunochemotherapy compared with a normative population (P < 0.01). A quarter to 50% of patients persistently reported to be slowed down, lethargic, or persistently worried about future health or was limited in social activities. Subsequently, patients reporting these symptoms/worries had a lower global health status/HRQoL.

CONCLUSION

Alertness for persistent symptoms that occur during and after treatment of FL patients is needed and may help to avoid lasting negative influence on their HRQoL.

Management of fatigue in patients with cancer -- a practical overview

Cancer-related fatigue (CRF) is a serious clinical problem and is one of the most common symptoms experienced by cancer patients. CRF has deleterious effects on many aspects of patient quality of life including their physical, psychological and social well-being. It can also limit their ability to function, socialise and participate in previously enjoyable activities. The aetiology of CRF is complex and multidimensional, involving many potentially contributing elements. These include tumour-related factors and comorbid medical/psychological conditions and also side effects associated with anti-cancer therapies or other medications. Barriers to the effective management of CRF exist both on the side of physicians and patients, and as a result CRF often remains unrecognised and undiscussed in clinical practice. A change of approach is required, where fatigue is treated as central to patient management during and after systemic anti-cancer treatment. In this review we summarise factors involved in the aetiology of CRF and the barriers to its effective management, as well as factors involved in the screening, diagnosis and treatment of cancer patients experiencing fatigue. Pharmacological and non-pharmacological approaches to its management are also reviewed. We suggest an algorithm for the process of managing CRF, guided by our experiences in The Netherlands, which we hope may provide a useful tool to healthcare professionals dealing with cancer patients in their daily practice. Although CRF is a serious and complex clinical problem, if it is worked through in a structured and comprehensive way, effective management has the potential to much improve patient quality of life.

Randomized controlled trial of a cognitive-behavioral therapy plus hypnosis intervention to control fatigue in patients undergoing radiotherapy for breast cancer

PURPOSE

The objective of this study was to test the efficacy of cognitive-behavioral therapy plus hypnosis (CBTH) to control fatigue in patients with breast cancer undergoing radiotherapy. We hypothesized that patients in the CBTH group receiving radiotherapy would have lower levels of fatigue than patients in an attention control group.

PATIENTS AND METHODS

Patients (n = 200) were randomly assigned to either the CBTH (n = 100; mean age, 55.59 years) or attention control (n = 100; mean age, 55.97 years) group. Fatigue was measured at four time points (baseline, end of radiotherapy, 4 weeks, and 6 months after radiotherapy). Fatigue was measured using the Functional Assessment of Chronic Illness Therapy (FACIT) -Fatigue subscale and Visual Analog Scales (VASs; Fatigue and Muscle Weakness).

RESULTS

The CBTH group had significantly lower levels of fatigue (FACIT) at the end of radiotherapy (z, 6.73; P < .001), 4-week follow-up (z, 6.98; P < .001), and 6-month follow-up (z, 7.99; P < .001) assessments. Fatigue VAS scores were significantly lower in the CBTH group at the end of treatment (z, 5.81; P < .001) and at the 6-month follow-up (z, 4.56; P < .001), but not at the 4-week follow-up (P < .07). Muscle Weakness VAS scores were significantly lower in the CBTH group at the end of treatment (z, 9.30; P < .001) and at the 6-month follow-up (z, 3.10; P < .02), but not at the 4-week follow-up (P < .13).

CONCLUSION

The results support CBTH as an evidence-based intervention to control fatigue in patients undergoing radiotherapy for breast cancer. CBTH is noninvasive, has no adverse effects, and its beneficial effects persist long after the last intervention session. CBTH seems to be a candidate for future dissemination and implementation.
