The effects of a six-week supervised multimodal exercise intervention during chemotherapy on cancer-related fatigue

Non-pharmacological treatment options for fatigue: A systematic review of RCTs in adults

OBJECTIVE

Fatigue is a significant contributor to the burden experienced by patients with chronic disorders. The development of standardized treatments is challenging due to the lack of consensus concerning the etiology of fatigue. The aim of this systematic review is to provide an overview of non-pharmacological interventions for fatigue. The efficacy and differences in fatigue treatment across conditions will be explored.

METHODS

A systematic literature search was conducted using the databases PubMed, Web of Science, PsycInfo and CINAHL. Trials were eligible when (1) adult patients (≥ 18 years old) with disorders causing fatigue were included, (2) non-pharmacological interventions performed, (3) treatment was compared to standard care, placebo or active control group, (4) fatigue was the only primary outcome assessed with a multidimensional tool, and (5) a randomized controlled trial (RCT) design was applied.

RESULTS

7592 papers were screened. 91 RCTs were eligible, with data reported in 95 papers. Specific fatigue interventions were present for a broad range of conditions. Findings demonstrated promising evidence for physical activity, CBT, online programs and multidimensional modules. Additional types of interventions were effective, but evidence was limited due to risk of bias and small sample sizes. Due to high heterogeneity concerning methodology, a meta-analysis was not possible.

CONCLUSION

Several non-pharmacological treatment options for fatigue are promising. No clear evidence was found that fatigue should be treated differently depending on the underlying condition. However, further research is necessary with a focus on a transdiagnostic approach to fatigue, high study quality and long-term follow-ups.

Resistance training for fatigue in people with cancer

BACKGROUND

Cancer-related fatigue (CRF) is one of the most common symptoms associated with cancer and its treatment. Different types of exercise have demonstrated beneficial effects on CRF. Previous evidence syntheses provided promising but inconclusive results when focusing on the effects of resistance training.

OBJECTIVES

To evaluate the effects of resistance training on CRF in people with cancer and, specifically, to compare the effects of resistance training with no training on CRF at: different periods of treatment in relation to anticancer therapy (before, during, or after anticancer therapy); different periods of assessment (up to 12 weeks after the intervention, between more than 12 weeks and less than six months after the intervention, or six months or longer after the intervention). Moreover, we wanted to compare the effects of resistance training with no training on quality of life (QoL), adverse events, depression, and anxiety.

SEARCH METHODS

We performed an extensive literature search in eight databases including CENTRAL, Medline, and Embase in October 2023. We searched trial registries for ongoing studies, and we integrated results from update searches of previously published Cochrane reviews.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared resistance training with no training in adults with any type of cancer who received resistance training initiated before, during, or after anticancer therapy. Eligible RCTs needed to evaluate CRF or QoL. Resistance training had to be structured, last for at least five sessions, and include face-to-face instruction. We excluded studies that randomised fewer than 20 participants per group.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology. For analyses, we pooled short-term, medium-term, and long-term effects (i.e. up to 12 weeks, between more than 12 weeks and less than six months, and six months or longer, after the intervention). We assessed risk of bias and certainty of the evidence using Cochrane's risk of bias tool (RoB 1), and the GRADE approach, respectively.

MAIN RESULTS

We included 21 RCTs with a total of 2221 participants, with diverse types of cancer, who received resistance training initiated during (14 studies), or after (7 studies) anticancer therapy. None of the studies investigated the effects of resistance training initiated before anticancer therapy. Here, we present the results on CRF, QoL, and adverse events. Results on depression and anxiety are reported in the full review. Resistance training during anticancer therapy Resistance training probably has a beneficial effect compared with no training on short-term CRF (mean difference (MD) on Functional Assessment of Chronic Illness Therapy - Fatigue scale (FACIT-Fatigue) 3.90, 95% confidence interval (CI) 1.30 to 6.51; scale from 0 to 52, higher values mean better outcome, minimal important difference (MID) 3; 12 RCTs, 1120 participants; moderate-certainty evidence). The evidence is very uncertain about the effect of resistance training compared with no training on medium-term CRF (MD on Multidimensional Fatigue Inventory -8.33, 95% CI -18.34 to 1.68; scale from 20 to 100, higher values mean worse outcome, MID 11.5; 1 RCT, 47 participants; very low-certainty evidence). The evidence is very uncertain about the effect of resistance training compared with no training on long-term CRF (MD on FACIT-Fatigue -0.70, 95% CI -4.16 to 2.76; 1 RCT, 133 participants; very low-certainty evidence). Resistance training may have a small beneficial effect compared with no training on short-term QoL (MD on EORTC QoL Questionnaire C30 - global health (QLQ-C30) 4.93, 95% CI 2.01 to 7.85; scale from 0 to 100, higher values mean better outcome, MID 10; 12 RCTs, 1117 participants; low-certainty evidence). The evidence is very uncertain about the effect of resistance training compared with no training on medium-term QoL (MD on QLQ-C30 6.48, 95% CI -4.64 to 17.60; 1 RCT, 42 participants; very low-certainty evidence). The evidence is very uncertain about the effect of resistance training compared with no training on long-term QoL (MD on Functional Assessment of Cancer Therapy - Anemia (FACT-An) 0.50, 95% CI -8.46 to 9.46; scale from 0 to 188; higher values mean better outcome, MID 7; 1 RCT, 133 participants; very low-certainty evidence). Only two RCTs (116 participants) reported data on adverse events for both the resistance training and the control arm. The evidence is very uncertain about the effect of resistance training compared with no training on the occurrence of adverse events (very low-certainty evidence). Resistance training after anticancer therapy The evidence is very uncertain about the effect of resistance training compared with no training on short-term CRF (MD on Chalder Fatigue Scale -0.27, 95% CI -2.11 to 1.57; scale from 0 to 33, higher values mean worse outcome, MID 2.3; 3 RCTs, 174 participants; very low-certainty evidence). Resistance training may have a small beneficial effect or no effect compared with no training on short-term QoL (MD on QLQ-C30 3.87, 95% CI -1.22 to 8.97; 4 RCTs, 243 participants; low-certainty evidence). None of the studies reported data on medium-, or long-term effects on CRF or QoL. Only three RCTs (238 participants) reported data on adverse events for both the resistance training and the control arm. The evidence is very uncertain about the effect of resistance training compared with no training on the occurrence of adverse events (very low-certainty evidence).

AUTHORS' CONCLUSIONS

Our review demonstrates beneficial effects of resistance training during anticancer therapy compared with no training on short-term CRF and QoL for people with cancer. Resistance training after anticancer therapy may also have a small beneficial effect on short-term QoL. Data on medium-, and long-term effects are sparse. In order to facilitate evidence syntheses beyond a narrative report of the data, investigators of resistance training programmes should report adverse events more consistently and completely for all study arms, including control groups.

Effect of resistance exercise on physical fitness, quality of life, and fatigue in patients with cancer: a systematic review

OBJECTIVE

The purpose of this study is to conduct a systematic review to assess the effects of different forms of resistance exercises (resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises) on physical fitness, quality of life (QOL), and fatigue of patients with cancer.

METHODS

We conducted a systematic review using the Cochrane Handbook for Systematic Reviews of Interventions guidelines. We searched PubMed, Web of Science, and Scopus databases for the studies from the establishment of the database to September 2023, including randomized controlled trials and clinical trials that evaluated the effects of different resistance exercise on physical fitness, QOL, and fatigue in all patients with cancer. Two reviewers independently assessed the quality of all the included studies using the Cochrane Handbook for Systematic Reviews of Interventions and MINORS scale. We divided the intervention into three types: resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises.

RESULTS

In total, 48 studies (3,843 participants) met the inclusion criteria. The three exercise intervention forms have significant effects on physical fitness and QOL, but the improvement effect on fatigue is not clear. A total of 34 studies reported significant and beneficial effects of resistance exercise on physical fitness across all types of cancer. There were 28 studies that reported significant or borderline improvement effects of resistance on QOL, and only 10 studies reported significant effects of resistance exercise interventions on fatigue improvement in patients with cancer.

CONCLUSIONS

Resistance exercise, resistance exercise combined with aerobic exercise, and resistance exercise combined with other exercises all have a positive effect on improving fitness and QOL in patients with cancer. Resistance exercise has an advantage in improving muscle strength, while combined resistance exercise has an advantage in improving QOL; however, there are no consistent findings in improving fatigue, although low-intensity resistance exercise is effective.

A qualitative study of barriers and facilitators for health behavior change in low-income men with prostate cancer

PURPOSE

Low-income prostate cancer survivors, who typically have worse outcomes and greater all-cause mortality, often have poor health-promoting behaviors. Our objective was to assess perceived facilitators of and barriers to healthy behavior change by interviewing low-income men with prostate cancer who received no-cost treatment through a state-funded program.

METHODS

Between September 2021 and April 2022, we conducted semi-structured interviews with 19 men (ages 60-75). Purposive sampling was utilized from participants of a cohort of men with prostate cancer from low-income backgrounds. Interviews were recorded, transcribed, and then coded by the authors to generate salient themes via thematic analysis.

RESULTS

We found internal characteristics and structural characteristics that functioned independently and in concert to promote and/or hinder healthy behavior change. Internal characteristics such as motivations (prostate cancer diagnosis, self-perceptions, support system, and preferences) and determination, defined as level of motivation, drove behavior actualization. Structural characteristics that influenced behavior change included resources (access to food and opportunities for exercise) and social support.

CONCLUSIONS

These outcomes suggest that motivation and determination can serve as protective facilitators encouraging healthy behaviors despite structural barriers low-income prostate cancer survivors may face. However, motivations challenged by financial constraints were not sufficient to guide healthy behavior change. With this in mind, we recommend that interventions promoting healthy behavior change among this population should focus on identifying and strengthening internal assets such as motivations, self-perceptions, preferences, and support systems.

Qualitative exploration of the perceptions of exercise in patients with cancer initiated during chemotherapy: a meta-synthesis

OBJECTIVE

To synthesise qualitative literature on (1) the perceptions of patients with cancer of participating in an exercise intervention while undergoing chemotherapy and (2) to inform and guide professionals in oncology and haematology practice.

DESIGN

A qualitative meta-synthesis based on Noblit and Hare's seven-step meta-ethnography.

DATA SOURCES

Six electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, EMBASE, PubMed, SCI-Expanded-SSCI and Scopus (final search June 2022) were used to identify qualitative literature containing individual or focus group interviews. The transparency of reporting for each study was assessed using the Consolidated criteria for Reporting Qualitative research checklist.

RESULTS

The search identified 5002 articles, 107 of which were selected for full-text review. Seventeen articles from five countries with patients undergoing chemotherapy during exercise interventions were included. Eleven articles were included in the meta-synthesis, which comprised 193 patients with various cancer diagnoses, disease stages, sexes and ages. Four main themes were identified: chemotherapy overpowers the body; exercise in battle with side effects; a break from gloomy thoughts; and a question of survivorship.

CONCLUSIONS AND IMPLICATIONS

The meta-synthesis emphasised that patients with cancer undergoing chemotherapy and simultaneously participating in exercise interventions may experience momentary relief from overwhelming side effects, even though full bodily recovery may be perceived as a distant prospect. The synthesis offers a sparse empirical basis for gaining insight into what patients experience existentially following exercise interventions. It is up to patients to independently apply the transfer value of exercise to their own existential circumstances.

Comparative effects of different types of exercise on health-related quality of life during and after active cancer treatment: A systematic review and network meta-analysis

BACKGROUND

The positive influence of most types of exercise has been reported repeatedly, but what the most effective exercise approaches are for improving health-related quality of life (HRQoL) in people with cancer remains unknown. The aim of this systematic review and network meta-analysis was to synthesize the evidence from intervention studies to assess the effects of different types of exercise on HRQoL during and after cancer treatment.

METHODS

MEDLINE, SPORTDiscus, the Cochrane Library, Web of Science, and Scopus were searched for randomized controlled trials aimed at testing the effects of exercise interventions meant to improve HRQoL in people with cancer. Separate analyses were conducted for HRQoL as measured by general and cancer-specific questionnaires. We also evaluated whether the effects of exercise were different during and after cancer treatment in both the physical and mental HRQoL domains.

RESULTS

In total, 93 studies involving 7435 people with cancer were included. Network effect size estimates comparing exercise intervention vs. usual care were significant for combined exercise (0.35, 95% confidence interval (95%CI): 0.14-0.56) for HRQoL as measured by general questionnaires, and for combined (0.31, 95%CI: 0.13-0.48), mind-body exercise (0.54, 95%CI: 0.18-0.89), and walking (0.39, 95%CI: 0.04-0.74) for HRQoL as measured by cancer-specific questionnaires.

CONCLUSION

Exercise programs combining aerobic and resistance training can be recommended to improve HRQoL during and after cancer treatment. The scarcity and heterogeneity of these studies prevents us from making recommendations about other exercise modalities due to insufficient evidence.

Effectiveness of Therapeutic Exercise Models on Cancer-Related Fatigue in Patients With Cancer Undergoing Chemotherapy: A Systematic Review and Network Meta-analysis

OBJECTIVE

To assess and compare the effectiveness of different exercise modalities in reducing cancer-related fatigue (CRF) in patients with cancer undergoing chemotherapy. Exercise intensities for selected exercise types were also compared.

DATA SOURCES

We conducted a search in MEDLINE, Embase, CINAHL, Scopus, SPORTDiscus, and Web of Science from inception to October 15, 2021.

STUDY SELECTION

Randomized controlled trials concerning the effectiveness of exercise modalities on CRF in patients with cancer undergoing chemotherapy were included.

DATA EXTRACTION

Study characteristics were extracted using a structured protocol. Methodological quality was assessed employing the PEDro scale and risk of bias was assessed using the Revised Cochrane Risk of Bias Tool for Randomized Trials. The certainty of evidence was assessed based on Grading of Recommendations, Assessment, Development and Evaluation. The measure of effect used was the adjusted standardized mean difference (SMD) or Hedge's g, together with the corresponding 95% confidence intervals (CI).

DATA SYNTHESIS

Forty-seven studies were included. Data were pooled employing a random-effects model. There was a trend that adding low-intensity aerobic and resistance exercise (SMD=1.28, 95% CI -0.18; 2.75, P=.086), or moderate-intensity aerobic and resistance exercise (SMD=0.85; 95% CI -0.12; 1.82, P=.087), was more effective than adding flexibility training to usual care (UC). There was also a trend that UC alone was less effective than adding moderate-intensity aerobic and resistance exercise (SMD=-0.47, 95% CI -0.96, 0.02, P=.060) to UC.

CONCLUSIONS

The addition of low- to moderate-intensity aerobic and/or resistance exercise demonstrated a positive trend for improvement in CRF in patients with cancer undergoing chemotherapy, when compared with UC alone or UC with flexibility training.

Which Exercise Approaches Work for Relieving Cancer-Related Fatigue? A Network Meta-analysis

OBJECTIVE: To determine the most effective exercise modalities for managing cancer-related fatigue during and after cancer treatment. DESIGN: Network meta-analysis (NMA) of randomized controlled trials. LITERATURE SEARCH: Seven electronic databases were systematically searched from inception to January 2022. STUDY SELECTION CRITERIA: Randomized controlled trials testing the effects of exercise on relieving cancer-related fatigue in adult patients with cancer. DATA SYNTHESIS: An NMA of 56 studies was conducted, and the PRISMA-NMA guidelines were followed when reporting results. To determine the most effective interventions, the surface under the cumulative ranking curve (SUCRA) value was calculated for each exercise modality. RESULTS: Combined aerobic and resistance exercise (standardized mean difference [SMD], 1.57; credible interval [CrI], 1.03-2.10), yoga (SMD, 1.02; CrI: 0.44, 1.60), and regular physical activity (SMD, 1.07; CrI: 0.21, 1.92) could significantly alleviate cancer-related fatigue compared to control groups (usual care, wait-list, and regular physical activity). Combined aerobic and resistance exercise (SUCRA, 97.2%) had the highest probability of efficacy, followed by yoga (SUCRA, 75.5%) and regular physical activity (SUCRA, 74.1%). During cancer treatment, combined aerobic and resistance exercise (SUCRA, 94.5%) ranked first in efficacy, followed by regular physical activity (SUCRA, 82.1%) and yoga (SUCRA, 73.8%). After cancer treatment, only combined aerobic and resistance exercise (SMD, 0.99; CrI: 0.13, 1.84) had a significant effect on cancer-related fatigue. CONCLUSION: Combined aerobic and resistance exercise, yoga, and regular physical activity were the most effective exercise modalities for alleviating cancer-related fatigue. Combined aerobic and resistance exercise is recommended during and after cancer treatment. J Orthop Sports Phys Ther 2023;53(6):1-10. Epub: 23 March 2023. doi:10.2519/jospt.2023.11251.

Physical rehabilitation for the management of cancer-related fatigue during cytotoxic treatment: a systematic review with meta-analysis

OBJECTIVE

To assess the effect of physical therapy on cancer-related fatigue (CRF) during cytotoxic anticancer treatment.

METHODS

Systematic review with meta-analysis of randomized clinical trials published from 2010 to 2021 (EMBASE, MEDLINE, PEDro; SciELO, and LILACS). Studies assessing the effect of supervised physical therapy (IG) for the management of CRF on adults undergoing anticancer treatment compared with a control group (CG) covering usual care or any uncontrolled practice, such as recommendations about exercise and health education, were included in this review.

RESULTS

A total of 22 studies were included in the SR and 21 in the meta-analysis, resulting in 1.992 individuals (CG = 973 and IG = 1.019). There was a reduction in general fatigue [SMD =  - 0.69; 95%CI (- 1.15, - 0.22) p < 0.01; I² = 87%; NNT = 3], with greater weight attributed to combined exercise (44%). Physical fatigue also reduced [SMD =  - 0.76; 95%CI (- 1.13, - 0.39) p < 0.01; I² = 90%; NNT = 2], with greater weight for resistance exercise (50%) and greater effect with combined exercise [SMD =  - 1.90; 95%CI (- 3.04, - 0.76) p < 0.01; I ² = 96%]. There was reduction in general fatigue with moderate intensity (74%) [SMD =  - 0.89; 95%CI (- 1.61, - 0.17) p < 0.02; I² = 90%] and physical fatigue [SMD =  - 1.00; 95%CI (- 1.54, - 0.46) p < 0.01; I² = 92%], while high intensity reduced only general fatigue [SMD =  - 0.35; 95%CI (- 0.51, - 0.20) p < 0.01; I² = 0%]. The number of overall and weekly sessions has been shown to contribute to the reduction of CRF.

CONCLUSION

Physical rehabilitation with moderate intensity promoted greater relief of general and physical fatigue. Even after controlling for high heterogeneity, the quality of evidence, summarized in GRADE, was considered moderate for general fatigue and low for physical fatigue.

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.

Effects of multimodal training program on muscle deoxygenation in women with breast cancer: A randomized controlled trial

Purpose

Chemotherapy and/or radiation are the most often delivered treatments to cancer patients. Usually during the adjuvant treatment, patients complain about fatigue. In addition, physical exercise during adjuvant treatment of cancer seems to have beneficial effects. The aim of this investigation was to assess the effects of multimodal aerobic and strength exercises programs on muscle deoxygenation of patients with breast cancer undergoing adjuvant chemotherapy treatment.

Methods

Thirty-two women with breast cancer (20 patients as the training group and 12 patients as the control group) undergoing adjuvant chemotherapy participated in the study. The training group took part in 6 weeks of supervised intermittent aerobic cycling, home-based walking, isometric and electrical muscle stimulation (EMS) exercise training programs. The Outcome measures were muscle deoxygenation (ΔHHb), Maximal Voluntary isometric Contraction (MViC) and Endurance Time (ET) before and after the training period.

Results

Compared to the control group, a significant increase in ΔHHb (P < 0.01) accompanied with an increase in ET (P < 0.01) and MViC (P < 0.01) of the quadriceps was obtained in the training group. However, no significant differences of MViC, ET and ΔHHb were observed in the control group.

Conclusion

Multimodal aerobic and strength exercise programs enhance muscle oxygen utilization, which may partly explain the improvement in muscular strength and endurance, and the reduction of muscle fatigue in patients with breast cancer during an adjuvant chemotherapy period.

Application of the Multidimensional Fatigue Inventory to Ethiopian Cancer Patients

Objectives: Fatigue is a frequent debilitating symptom associated with cancer. However, scientific data on cancer-related fatigue is scarce in developing nations. This work examines psychometric properties of the multidimensional fatigue inventory (MFI-20) and analyzes the level of fatigue among Ethiopian patients with cancer in comparison with data from Germany.

Methods: A sample of 256 patients with cancer drawn from a hospital in Ethiopia was examined with the MFI-20 and the European Organization for Research and Treatment of Cancer Quality of Life questionnaire (EORTC QLQ-C30). A comparative sample of 780 German patients with cancer served as the control.

Results: The MFI-20 scales and total score showed acceptable reliability (α = 0.60–0.93) with a considerable convergent validity between MFI-20 and the EORTC QLQ-C30 fatigue scale (r = 0.67–0.75). The Ethiopian patients with cancer reported higher levels of fatigue than the German patients. Analyses of variance showed that Ethiopian patients with cancer who were illiterate, having advanced cancer, and those who did not receive either surgery or chemotherapy reported especially high levels of fatigue.

Conclusion: The MFI-20 is a fairly reliable and valid instrument to be used with Amharic speaking patients with cancer. The high level of fatigue in these patients implies that appropriate cancer care is needed in developing countries.

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.

Attention to principles of exercise training: an updated systematic review of randomized controlled trials in cancers other than breast and prostate

BACKGROUND

The primary objective of this systematic review was to update our previous review on randomized controlled trials (RCTs) of exercise in cancers other than breast or prostate, evaluating: 1) the application of principles of exercise training within the exercise prescription; 2) reporting of the exercise prescription components (i.e., frequency, intensity, time, and type (FITT)); and 3) reporting of participant adherence to FITT. A secondary objective was to examine whether reporting of these interventions had improved over time.

METHODS

MEDLINE, EMBASE, CINAHL and SPORTDiscus databases were searched from 2012 to 2020. Eligible studies were RCTs of at least 4 weeks of aerobic and/or resistance exercise that reported on physiological outcomes relating to exercise (e.g., aerobic capacity, muscular strength) in people with cancer other than breast or prostate.

RESULTS

Eighty-six new studies were identified in the updated search, for a total of 107 studies included in this review. The principle of specificity was applied by 91%, progression by 32%, overload by 46%, initial values by 72%, reversibility by 7% and diminishing returns by 5%. A significant increase in the percentage of studies that appropriately reported initial values (46 to 80%, p < 0.001) and progression (15 to 37%, p = 0.039) was found for studies published after 2011 compared to older studies. All four FITT prescription components were fully reported in the methods in 58% of all studies, which was higher than the proportion that fully reported adherence to the FITT prescription components in the results (7% of studies). Reporting of the FITT exercise prescription components and FITT adherence did not improve in studies published after 2011 compared to older studies.

CONCLUSION

Full reporting of exercise prescription and adherence still needs improvement within exercise oncology RCTs. Some aspects of exercise intervention reporting have improved since 2011, including the reporting of the principles of progression and initial values. Enhancing the reporting of exercise prescriptions, particularly FITT adherence, may provide better context for interpreting study results and improve research to practice translation.

Above and beyond cancer: a novel approach to growth and resilience in cancer survivors

Background

Although cancer diagnosis and treatment frequently cause distress, many survivors report personal growth, change, and transformation. To better understand these dynamics, we used a qualitative approach to study twenty-seven heterogeneous cancer survivors who participated in physically and emotionally challenging journeys through the Above and Beyond Cancer organization. Groups traveled to Kathmandu (Nepal), Mt. Kilimanjaro (Tanzania), and Mt. Kailash (China), and volunteered at nearby cancer hospitals.

Methods

Survivors completed short essays and surveys pre-departure, 3 weeks, and 3 months post-trip. Qualitative responses were categorized into themes by 4 independent reviewers following consensus, and quantitative measures assessed sociodemographic characteristics and mood.

Results

Qualitative findings highlighted the role of new experiences and social support in enabling participants to develop new meaning, growth, and a new sense of their capabilities. Quantitative measures showed that anxiety of participants decreased over time.

Conclusions

This study points to lifestyle undertakings that can support personal growth in cancer survivors.

Outcomes Related to Activity Performance and Participation of Non-Pharmacological Cancer-Related Fatigue Interventions

Increased cancer survivorship means more people are living with cancer-related fatigue (CRF), which is associated with activity performance limitations, restricted participation in meaningful life roles, and reduced quality of life. To identify whether non-pharmacological interventions that are effective in minimizing CRF also have an impact on everyday activity performance and participation outcomes for adult cancer survivors. This is a systematic review with narrative synthesis. Eight databases were searched (Medline, CINAHL, PsychINFO, EMBASE, Scopus, OT Seeker, CENTRAL, Cochrane SR database), from 2000 to 2020 for randomized controlled trials of effective non-pharmacological CRF interventions in adult cancer survivors with fatigue. A total of 5,762 studies were identified of which 29 studies were reviewed. In 28 studies, quality of life was investigated as a primary or secondary outcome, where concepts of participation or activity performance were used. Review findings indicate there is insufficient evidence to determine whether activity performance and participation is affected by CRF interventions.

Effects of high-intensity training on the quality of life of cancer patients and survivors: a systematic review with meta-analysis

Cancer and associated medical treatments affect patients' health-related quality of life (HRQoL) by decreasing functional dimensions of physical, social, cognitive, and emotional well-being, while increasing short and late-term symptoms. Exercise, however, is demonstrated to be a useful therapy to improve cancer patients' and survivors' HRQoL, yet the effectiveness of high-intensity training (HIT) exercise is uncertain. This systematic review and meta-analysis aimed to analyse the effects of HIT on HRQoL dimensions in cancer patients and survivors as well as evaluate the optimal prescription of HIT. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) and examined Web of Science and PubMed (Medline) databases. Data were analysed utilizing Review Manager Software. Twenty-two articles were included in the systematic review and 17 in the meta-analysis. Results showed HIT improved global quality of life, physical functioning, role functioning, social functioning, cognitive functioning, fatigue, pain, dyspnea, and insomnia, compared to an inactive control group, yet no differences were found between HIT and low to moderate-intensity exercise interventions. Particular improvements in HRQoL were observed during cancer treatment and with a training duration of more than eight weeks, a frequency of 2 days/week, and a volume of at least 120 min/week, including 15 min or more of HIT. Our findings whilst encouraging, highlight the infancy of the extant evidence base for the role of HIT in the HRQoL of cancer patients and survivors.

"Doing What Only I Can Do": Experiences From Participating in a Multimodal Exercise-Based Intervention in Older Patients With Advanced Cancer-A Qualitative Explorative Study

Background

Sparse evidence exists regarding the feasibility and patients’ experiences of exercise programs among older cancer populations.

Objective

The aim of this study was to explore the experiences of older patients with advanced cancer who participated in a 12-week supervised and multimodal exercise program in a hospital setting.

Methods

Individual interviews were conducted with 18 participants (≥65 years) with advanced cancer who completed the intervention program regardless of compliance rate. In addition, written evaluation questionnaires were collected. Data were analyzed using thematic analysis.

Results

Three main themes were identified: (1) Motivated to strengthen body and mind, with the subthemes “Doing what only I can do” and “Reaching goals with support from healthcare professionals and peers”; (2) Exercise as an integrated part of the treatment course; and (3) Overcoming undeniable physical limitations.

Conclusions

The participants experienced several benefits from participation, including physical improvements, increased energy, reduction of symptoms, and improved social engagement. Goal setting, being positively pushed and cheered on, and integration of fun games increased motivation. In contrast, being pushed beyond physical limitations and experiencing severe symptoms were experienced as barriers toward exercising. Adherence to the exercise program was facilitated by coordinating a tailored program with medical appointments and receiving comprehensive support and guidance.

Implications for Practice

Multimodal exercise programs seem to be beneficial for older patients with advanced cancer and should be coordinated with oncological treatment in combination with targeted support and advice on symptom management.

Trajectories of Self-reported Physical Functioning and Symptoms in Lung Cancer Survivors

BACKGROUND

Lung cancer survivors are at risk of accelerated declines in physical functioning attributed to cancer treatment. However, it is unknown whether patients experience the same rate of functional decline and how symptoms may contribute to different trajectories.

OBJECTIVES

The aims of this study were to identify interindividual differences in the pattern and rate of change in self-reported functioning in lung cancer survivors and examine whether and how symptoms are related to physical functioning over time.

METHODS

This was a secondary data analysis in 72 lung cancer survivors. Multilevel modeling was used to estimate trajectories of self-reported physical functioning over 1 year and assess the relation between functioning, fatigue, depressive symptoms, and pain severity across time.

RESULTS

Within the sample, average physical functioning did not significantly decrease (coefficient, -0.46; 95% confidence interval [CI] = -2.85 to 0.94) over time. However, among individual lung cancer survivors, baseline physical functioning varied significantly (SD, 20.76; 95% CI, 16.84-25.59) and changed at significantly different rates over 1 year (SD, 3.50; 95% CI, 2.13-5.68). Fatigue, assessed over 1 year, was the only significant symptom predictor of physical functioning changes over time (coefficient = 1.03; 95% CI, 0.79-1.27).

CONCLUSIONS

In this sample of lung cancer survivors, not all survivors experienced the same rate of self-reported functional decline and those with lower levels of fatigue reported better physical functioning.

IMPLICATIONS FOR PRACTICE

Nurses should recognize that some lung cancer survivors may have faster rates of functional declines than others, which may be related to fatigue severity. Early identification and management of fatigue could help avoid or delay future disability.

The Relationship between Fatigue and Actigraphy-Derived Sleep and Rest-Activity Patterns in Cancer Survivors

Cancer-related fatigue can continue long after curative cancer treatment. The aim of this study was to investigate sleep and rest–activity cycles in fatigued and non-fatigued cancer survivors. We hypothesized that sleep and rest–activity cycles would be more disturbed in people experiencing clinically-relevant fatigue, and that objective measures of sleep would be associated with the severity of fatigue in cancer survivors. Cancer survivors (n = 87) completed a 14-day wrist actigraphy measurement to estimate their sleep and rest–activity cycles. Fatigue was measured using the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-F). Participants were dichotomised into two groups using a previously validated score (fatigued n = 51 and non-fatigued n = 36). The participant’s perception of sleep was measured using the Insomnia Severity Index (ISI). FACIT-F score was correlated with wake after sleep onset (r = −0.28; p = 0.010), sleep efficiency (r = 0.26; p = 0.016), sleep onset latency (r = −0.31; p = 0.044) and Insomnia Severity Index (ISI) score (r = −0.56; p < 0.001). The relative amplitude of the rest–activity cycles was lower in the fatigued vs. the non-fatigued group (p = 0.017; d = 0.58). After treatment for cancer, the severity of cancer-related fatigue is correlated with specific objective measures of sleep, and there is evidence of rest–activity cycle disruption in people experiencing clinically-relevant fatigue.

Attenuating Treatment-Related Cardiotoxicity in Women Recently Diagnosed With Breast Cancer via a Tailored Therapeutic Exercise Program: Protocol of the ATOPE Trial

OBJECTIVE

Therapeutic exercise is already used to ameliorate some of the side effects of cancer treatment. Recent studies examined its preventive potential regarding treatment-related toxicity, which can increase the risk of functional decline and lead to disease recurrence and death. This trial will examine whether the Tailored Therapeutic Exercise and Recovery Strategies (ATOPE) program, performed before treatment, can mitigate the onset and extent of cardiotoxicity beyond that achieved when the program is followed during treatment in recently diagnosed breast cancer patients.

METHODS

The intervention has a preparatory phase plus 12 to 18 sessions of tailored, high-intensity exercise, and post-exercise recovery strategies. A total of 120 women recently diagnosed with breast cancer, at risk of cardiotoxicity due to anticancer treatment awaiting surgery followed by chemotherapy and/or radiotherapy, will be randomized to either group. In a feasibility study, measurements related to recruitment rate, satisfaction with the program, adherence to them, the retention of participants, safety, and adverse effects will be explored. In the main trial, the efficacy of these interventions will be examined. The major outcome will be cardiotoxicity, assessed echocardiographically via the left ventricular ejection fraction. Other clinical, physical, and anthropometric outcomes and biological and hormonal variables will also be assessed after diagnosis, after treatment, 1 year after treatment ends, and 3 years after treatment ends.

CONCLUSION

Given its potential effect on patient survival, the mitigation of cardiotoxicity is a priority, and physical therapists have an important role in this mitigation. If the ATOPE intervention performed before treatment returns better cardioprotection results, it may be recommendable that patients recently diagnosed follow this program.

IMPACT

The ATOPE program will highlight the need for a physical therapist intervention from the moment of diagnosis, in the prevention or mitigation of cardiotoxicity, in women with breast cancer. It could help physical therapists to establish an adequate therapeutic exercise dose adapted to breast cancer patients and to propose correct therapeutic exercise prescription according to the assimilation of the sessions.

Validation of the Return To Work Self-Efficacy questionnaire in a population of employees undergoing treatment for cancer

OBJECTIVE

Several Return To Work Self-Efficacy (RTWSE) questionnaires have been developed and found relevant to understanding the return to work (RTW) process of employees with various health problems, including employees with cancer. The aim of the present study was to examine the reliability and validity of the Danish 19-item RTWSE questionnaire (RTWSE-19^DK ) in a sample of employees with cancer.

METHODS

Employees undergoing treatment for cancer completed the RTWSE-19^DK at baseline (n = 68) and at 1 week (n = 49). Additional questionnaires measured work ability, cancer-related self-efficacy and psychological distress. Internal consistency, test-retest reliability and construct validity were examined.

RESULTS

The total and the three subscales of the RTWSE-19^DK showed good internal consistencies with Cronbach's alphas between 0.90 and 0.97 and high test-retest reliability with Intraclass Correlation Coefficients between 0.84 and 0.90. Examining construct validity, the RTWSE-19^DK showed medium and large correlations with cancer-related self-efficacy (r = 0.54), mental work ability (r = 0.51), and general work ability (r = 0.35), small correlations with physical work ability (r = 0.26) and anxiety (r = -0.10), and no correlations with depression (r = -0.08) and test date (r = 0.03).

CONCLUSION

The RTWSE-19^DK showed good reliability and adequate validity in employees undergoing cancer treatment. In clinical practice, the RTWSE-19 questionnaire may help practitioners identify areas of concern in the RTW process of cancer patients.

Women's Experiences After Ovarian Cancer Surgery: Distress, Uncertainty, and the Need for Occupational Therapy

IMPORTANCE

Despite the growing literature on the association of functional, physical, and quality-of-life (QOL) deficits with poor postoperative outcomes, there is a gap in the literature identifying women's occupational performance needs after ovarian cancer surgery.

OBJECTIVE

To describe the experiences of women hospitalized after ovarian cancer surgery to identify potential areas for intervention. Goals were to (1) identify functional needs and limitations at time of discharge as measured by the typical acute care occupational therapy evaluation and semistructured interview and (2) understand the women's perspectives of their needs for occupational therapy and a safe return to home.

DESIGN

Single-arm, cross-sectional descriptive study. Mixed-methods data collection and analysis.

SETTING

Academic cancer center.

PARTICIPANTS

Women with ovarian cancer (N = 11) who had completed surgery.

INTERVENTION

Semistructured interviews and patient-reported outcome measures (PROMs) completed postsurgery.

OUTCOMES AND MEASURES

PROMs included the National Comprehensive Cancer Network (NCCN) Distress Thermometer and Problem List, the PROMIS® Global Physical Health (GPH) and Global Mental Health (GMH) scales, and the Possibilities for Activity Scale-Women (PActS-W).

RESULTS

The mean NCCN Distress score was 6.0 (standard deviation [SD] = 3.1, with the top three concerns being pain (80%), worry (80%), and fatigue (78%). Mean GPH and GMH T scores were 38.0 (SD = 8.8) and 48.2 (SD = 8.4), respectively. Women scored a mean of 39.2 (SD = 11.2, range = 26-58) on the PActS-W. Thematic analyses found that the women were uncertain about potential functional limitations and significantly distressed.

CONCLUSION AND RELEVANCE

Women with ovarian cancer experienced high levels of uncertainty and distress after surgery. Integrating in-home or community-based occupational therapy into routine care could decrease functional distress and uncertainty and help women manage concerns related to pain, worry, and fatigue.

WHAT THIS ARTICLE ADDS

This study suggests that occupational therapy evaluation and intervention are needed to decrease distress and improve QOL of women upon discharge after ovarian cancer surgery.

Role of Kinematics Assessment and Multimodal Sensorimotor Training for Motion Deficits in Breast Cancer Chemotherapy-Induced Polyneuropathy: A Perspective on Virtual Reality Avatars

Chemotherapy-induced polyneuropathy (CIPN), one of the most severe and incapacitating side effects of chemotherapeutic drugs, is a serious concern in breast cancer therapy leading to dose diminution, delay, or cessation. The reversibility of CIPN is of increasing importance since active chemotherapies prolong survival. Clinical assessment tools show that patients experiencing sensorimotor CIPN symptoms not only do they have to cope with loss in autonomy and life quality, but CIPN has become a key restricting factor in treatment. CIPN incidence poses a clinical challenge and has lacked established and efficient therapeutic options up to now. Complementary, non-opioid therapies are sought for both prevention and management of CIPN. In this perspective, we explore the potential that digital interventions have for sensorimotor CIPN rehabilitation in breast cancer patients. Our primary goal is to emphasize the benefits and impact that Virtual Reality (VR) avatars and Machine Learning have in combination in a digital intervention aiming at (1) assessing the complete kinematics of deficits through learning underlying patient sensorimotor parameters, and (2) parameterize a multimodal VR simulation to drive personalized deficit compensation. We support our perspective by evaluating sensorimotor effects of chemotherapy, the metrics to assess sensorimotor deficits, and relevant clinical studies. We subsequently analyse the neurological substrate of VR sensorimotor rehabilitation, with multisensory integration acting as a key element. Finally, we propose a closed-loop patient-centered design recommendation for CIPN sensorimotor rehabilitation. Our aim is to provoke the scientific community toward the development and use of such digital interventions for more efficient and targeted rehabilitation.

Thromboembolic events after high-intensity training during cisplatin-based chemotherapy for testicular cancer: Case reports and review of the literature

The randomized "Testicular cancer and Aerobic and Strength Training trial" (TAST-trial) aimed to evaluate the effect of high-intensity interval training (HIIT) on cardiorespiratory fitness during cisplatin-based chemotherapy (CBCT) for testicular cancer (TC). Here, we report on an unexpected high number of thromboembolic (TE) events among patients randomized to the intervention arm, and on a review of the literature on TE events in TC patients undergoing CBCT. Patients aged 18 to 60 years with a diagnosis of metastatic germ cell TC, planned for 3 to 4 CBCT cycles, were randomized to a 9 to 12 weeks exercise intervention, or to a single lifestyle counseling session. The exercise intervention included two weekly HIIT sessions, each with 2 to 4 intervals of 2 to 4 minutes at 85% to 95% of peak heart rate. The study was prematurely discontinued after inclusion of 19 of the planned 94 patients, with nine patients randomized to the intervention arm and 10 to the control arm. Three patients in the intervention arm developed TE complications; two with pulmonary embolism and one with myocardial infarction. All three patients had clinical stage IIA TC. No TE complications were observed among patients in the control arm. Our observations indicate that high-intensity aerobic training during CBCT might increase the risk of TE events in TC patients, leading to premature closure of the TAST-trial.

Effect of Baduanjin Qigong Exercise on Cancer-Related Fatigue in Patients with Colorectal Cancer Undergoing Chemotherapy: A Randomized Controlled Trial

BACKGROUND

Cancer-related fatigue (CRF) is one of the most troubling symptoms of cancer patients during chemotherapy, and no gold standard for the treatment of CRF has been established.

OBJECTIVE

This study aimed to examine the effects of the Baduanjin qigong on patients with colorectal cancer and CRF, and to explore its intervention effects.

METHODS

This was an open-label, randomized controlled clinical trial. Ninety patients with chemotherapy-treated colorectal cancer and CRF were randomized to a Baduanjin exercise group or a routine care group. The primary outcome was the Brief Fatigue Inventory (BFI) score at 24 weeks. The secondary outcomes were the Karnofsky Performance Status (KPS) and Pittsburgh Sleep Quality Index (PSQI) scores at 24 weeks.

RESULTS

There were no significant differences between the two groups in CRF level at baseline and 12 weeks. At 24 weeks, the proportion of patients with moderate-to-severe CRF was significantly smaller in the exercise group than in the control group (23.2 vs. 59.1%, p < 0.01). The KPS and PSQI scores were similar in the two groups at baseline and 12 weeks, but they were significantly higher and lower, respectively, at 24 weeks in the exercise group compared with the control group (KPS score: 89.3 ± 8.3 vs. 75.2 ± 11.5, p < 0.01; PSQI score: 4.1 ± 1.1 vs. 6.9 ± 2.0, p < 0.01). Significant time-group interactions were observed for all three scores (all p < 0.01).

CONCLUSIONS

Baduanjin qigong exercise can relieve CRF in patients with colorectal cancer undergoing chemotherapy and can improve their physical activity level and their quality of sleep.

Effects of combined supervised intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory responses in women with breast cancer

BACKGROUND

The aim of this investigation was to study the effects of supervised combined intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory fitness in women with breast cancer during adjuvant chemotherapy treatment.

METHODS

Thirty-two women with breast cancer undertaking adjuvant chemotherapy participated in the study (trained group n=20 and control group n=12). The trained group carried out 6weeks of supervised intermittent cycling aerobic, muscle strength and home-based walking training programs. The self-selected walking speed (WS), walking distance covered (WD), heart rate (rHR), blood lactate ([La]b) concentration and rating of perceived exertion (RPE) were assessed in the two groups during the 6-min walking test before and after the training period.

RESULTS

Compared to controls, a significant increase in the WS (P<0.01) and the WD (P<0.01) accompanied by a significant decrease in resting rHR (P<0.01), exercising HR6' (P<0.01), [La]b (P<0.05), HR6'/WS (P<0.01) and [La]b/WS ratios (P<0.01) was reported in the trained group. However, a significant decrease both in WD (P<0.01) and WS (P<0.01) has been observed in the controls. No significant difference was observed in resting HR, exercising HR6', [La]b, HR6'/WS, and [La]b/WS ratios were observed in the control group. A significant improvement was observed for RPE in training group (P<0.05). However, no difference was shown in controls.

CONCLUSION

Combined training based on intermittent aerobic exercise, muscle strength and walking improve cardiorespiratory responses and reduce the perception of fatigue in women with breast cancer.

Role of Sonification and Rhythmic Auditory Cueing for Enhancing Gait Associated Deficits Induced by Neurotoxic Cancer Therapies: A Perspective on Auditory Neuroprosthetics

Patients undergoing chemotherapy, radiotherapy, and immunotherapy experience neurotoxic changes in the central and peripheral nervous system. These neurotoxic changes adversely affect functioning in the sensory, motor, and cognitive domains. Thereby, considerably affecting autonomic activities like gait and posture. Recent evidence from a range of systematic reviews and meta-analyses have suggested the beneficial influence of music-based external auditory stimulations i.e., rhythmic auditory cueing and real-time auditory feedback (sonification) on gait and postural stability in population groups will balance disorders. This perspective explores the conjunct implications of auditory stimulations during cancer treatment to simultaneously reduce gait and posture related deficits. Underlying neurophysiological mechanisms by which auditory stimulations might influence motor performance have been discussed. Prompt recognition of this sensorimotor training strategy in future studies can have a widespread impact on patient care in all areas of oncology.

Interventions for promoting habitual exercise in people living with and beyond cancer

BACKGROUND

This is an updated version of the original Cochrane Review published in the Cochrane Library 2013, Issue 9. Despite good evidence for the health benefits of regular exercise for people living with or beyond cancer, understanding how to promote sustainable exercise behaviour change in sedentary cancer survivors, particularly over the long term, is not as well understood. A large majority of people living with or recovering from cancer do not meet current exercise recommendations. Hence, reviewing the evidence on how to promote and sustain exercise behaviour is important for understanding the most effective strategies to ensure benefit in the patient population and identify research gaps.

OBJECTIVES

To assess the effects of interventions designed to promote exercise behaviour in sedentary people living with and beyond cancer and to address the following secondary questions: Which interventions are most effective in improving aerobic fitness and skeletal muscle strength and endurance? Which interventions are most effective in improving exercise behaviour amongst patients with different cancers? Which interventions are most likely to promote long-term (12 months or longer) exercise behaviour? What frequency of contact with exercise professionals and/or healthcare professionals is associated with increased exercise behaviour? What theoretical basis is most often associated with better behavioural outcomes? What behaviour change techniques (BCTs) are most often associated with increased exercise behaviour? What adverse effects are attributed to different exercise interventions?

SEARCH METHODS

We used standard methodological procedures expected by Cochrane. We updated our 2013 Cochrane systematic review by updating the searches of the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, Embase, AMED, CINAHL, PsycLIT/PsycINFO, SportDiscus and PEDro up to May 2018. We also searched the grey literature, trial registries, wrote to leading experts in the field and searched reference lists of included studies and other related recent systematic reviews.

SELECTION CRITERIA

We included only randomised controlled trials (RCTs) that compared an exercise intervention with usual care or 'waiting list' control in sedentary people over the age of 18 with a homogenous primary cancer diagnosis.

DATA COLLECTION AND ANALYSIS

In the update, review authors independently screened all titles and abstracts to identify studies that might meet the inclusion criteria, or that could not be safely excluded without assessment of the full text (e.g. when no abstract is available). We extracted data from all eligible papers with at least two members of the author team working independently (RT, LS and RG). We coded BCTs according to the CALO-RE taxonomy. Risk of bias was assessed using the Cochrane's tool for assessing risk of bias. When possible, and if appropriate, we performed a fixed-effect meta-analysis of study outcomes. If statistical heterogeneity was noted, a meta-analysis was performed using a random-effects model. For continuous outcomes (e.g. cardiorespiratory fitness), we extracted the final value, the standard deviation (SD) of the outcome of interest and the number of participants assessed at follow-up in each treatment arm, to estimate the standardised mean difference (SMD) between treatment arms. SMD was used, as investigators used heterogeneous methods to assess individual outcomes. If a meta-analysis was not possible or was not appropriate, we narratively synthesised studies. The quality of the evidence was assessed using the GRADE approach with the GRADE profiler.

MAIN RESULTS

We included 23 studies in this review, involving a total of 1372 participants (an addition of 10 studies, 724 participants from the original review); 227 full texts were screened in the update and 377 full texts were screened in the original review leaving 35 publications from a total of 23 unique studies included in the review. We planned to include all cancers, but only studies involving breast, prostate, colorectal and lung cancer met the inclusion criteria. Thirteen studies incorporated a target level of exercise that could meet current recommendations for moderate-intensity aerobic exercise (i.e.150 minutes per week); or resistance exercise (i.e. strength training exercises at least two days per week).Adherence to exercise interventions, which is crucial for understanding treatment dose, is still reported inconsistently. Eight studies reported intervention adherence of 75% or greater to an exercise prescription that met current guidelines. These studies all included a component of supervision: in our analysis of BCTs we designated these studies as 'Tier 1 trials'. Six studies reported intervention adherence of 75% or greater to an aerobic exercise goal that was less than the current guideline recommendations: in our analysis of BCTs we designated these studies as 'Tier 2 trials.' A hierarchy of BCTs was developed for Tier 1 and Tier 2 trials, with programme goal setting, setting of graded tasks and instruction of how to perform behaviour being amongst the most frequent BCTs. Despite the uncertainty surrounding adherence in some of the included studies, interventions resulted in improvements in aerobic exercise tolerance at eight to 12 weeks (SMD 0.54, 95% CI 0.37 to 0.70; 604 participants, 10 studies; low-quality evidence) versus usual care. At six months, aerobic exercise tolerance was also improved (SMD 0.56, 95% CI 0.39 to 0.72; 591 participants; 7 studies; low-quality evidence).

AUTHORS' CONCLUSIONS

Since the last version of this review, none of the new relevant studies have provided additional information to change the conclusions. We have found some improved understanding of how to encourage previously inactive cancer survivors to achieve international physical activity guidelines. Goal setting, setting of graded tasks and instruction of how to perform behaviour, feature in interventions that meet recommendations targets and report adherence of 75% or more. However, long-term follow-up data are still limited, and the majority of studies are in white women with breast cancer. There are still a considerable number of published studies with numerous and varied issues related to high risk of bias and poor reporting standards. Additionally, the meta-analyses were often graded as consisting of low- to very low-certainty evidence. A very small number of serious adverse effects were reported amongst the studies, providing reassurance exercise is safe for this population.

[Physical Activity and Cancer]

Physical Activity and Cancer Abstract. This article aims to summarize the literature on the role of physical activity in cancer patients and to propose exercise programs based on studies and recommendations. Medical advances with improved early diagnosis and treatment have increased the number of cancer survivors. At the same time, the quality of life of these patients must also be improved. In the different stages of the disease physical activity has an important role to play with its beneficial effects on fatigue, physical condition, mood etc. Collaboration between health system actors and patient education are the key to success in this multi-disciplinary care.

Does Jacobson's relaxation technique reduce consumption of psychotropic and analgesic drugs in cancer patients? A multicenter pre-post intervention study

Background

Cancer patients often suffer from emotional distress as a result of the oncological process. The purpose of our study was to determine whether practice of Jacobson’s relaxation technique reduced consumption of psychotropic and analgesic drugs in a sample of cancer patients.

Methods

This was a multicenter pre–post intervention design. Participants were 272 patients aged over 18 years attending 10 Spanish public hospitals with oncological pathologies and anxiety symptoms. The intervention consisted of a protocol of abbreviated progressive muscle relaxation training developed by Bernstein and Borkovec. This was followed up by telephone calls over a 1-month period. The intervention was performed between November 2014 and October 2015. Sociodemographic variables related to the oncological process, mental health variables, and intervention characteristics were measured.

Results

A reduction in the consumption of psychotropic and analgesic drugs was observed throughout the follow-up period. Improvement was observed throughout the 4-week follow-up for all the parameters assessed: anxiety, relaxation, concentration, and mastery of the relaxation technique.

Conclusions

The practice of abbreviated Jacobson’s relaxation technique can help to decrease the consumption of psychotropic and analgesic drugs. Patients experienced positive changes in all the evaluated parameters, at least during the 1-month follow-up. To confirm these findings, additional long-term studies are needed that include control groups.

The Impact of Exercise on Cancer Mortality, Recurrence, and Treatment-Related Adverse Effects

The combination of an increasing number of new cancer cases and improving survival rates has led to a large and rapidly growing population with unique health-care requirements. Exercise has been proposed as a strategy to help address the issues faced by cancer patients. Supported by a growing body of research, major health organizations commonly identify the importance of incorporating exercise in cancer care and advise patients to be physically active. This systematic review comprehensively summarizes the available epidemiologic and randomized controlled trial evidence investigating the role of exercise in the management of cancer. Literature searches focused on determining the potential impact of exercise on 1) cancer mortality and recurrence and 2) adverse effects of cancer and its treatment. A total of 100 studies were reviewed involving thousands of individual patients whose exercise behavior was assessed following the diagnosis of any type of cancer. Compared with patients who performed no/less exercise, patients who exercised following a diagnosis of cancer were observed to have a lower relative risk of cancer mortality and recurrence and experienced fewer/less severe adverse effects. The findings of this review support the view that exercise is an important adjunct therapy in the management of cancer. Implications on cancer care policy and practice are discussed.

The impact of muscle relaxation techniques on the quality of life of cancer patients, as measured by the FACT-G questionnaire

INTRODUCTION

Patients with cancer frequently suffer from emotional distress, characterized by psychological symptoms such as anxiety or depression. The presence of psychological symptoms combined with the complex nature of oncology processes can negatively impact patients' quality of life. We aimed to determine the impact of a relaxation protocol on improving quality of life in a sample of oncological patients treated in the Spanish National Public Health System.

MATERIALS AND METHODS

We conducted a multicenter interventional study without a control group. In total, 272 patients with different oncologic pathologies and showing symptoms of anxiety were recruited from 10 Spanish public hospitals. The intervention comprised abbreviated progressive muscle relaxation training, according to Bernstein and Borkovec. This was followed by weekly telephone calls to each patient over a 1-month period. We collected sociodemographic variables related to the disease process, including information about mental health and the intervention. Patients' quality of life was assessed using the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire. Bivariate and univariate analyses were performed, along with an analysis of multiple correspondences to identify subgroups of patients with similar variations on the FACT-G.

RESULTS

Patients showed statistically significant improvements on the FACT-G overall score (W = 16806; p<0.001), with an initial mean score of 55.33±10.42 and a final mean score of 64.49±7.70. We also found significant improvements for all subscales: emotional wellbeing (W = 13118; p<0.001), functional wellbeing (W = 16155.5; p<0.001), physical wellbeing (W = 8885.5; p<0.001), and social and family context (W = -1840; p = 0.037).

CONCLUSIONS

Patients with cancer who learned and practiced abbreviated progressive muscle relaxation experienced improvement in their perceived quality of life as measured by the FACT-G. Our findings support a previous assumption that complementary techniques (including relaxation techniques) are effective in improving the quality of life of patients with cancer.

Exercise for people with cancer: a systematic review

BACKGROUND

This systematic review was completed by the Exercise for People with Cancer Guideline Development Group, a group organized by Cancer Care Ontario's Program in Evidence-Based Care (pebc). It provides background and guidance for clinicians with respect to exercise for people living with cancer in active and post treatment. It focuses on the benefits of specific types of exercise, pre-screening requirements for new referrals, safety concerns, and delivery models.

METHODS

Using the pebc's standardized approach, medline and embase were systematically searched for existing guidelines, systematic reviews, and primary literature.

RESULTS

The search identified two guidelines, eighteen systematic reviews, and twenty-nine randomized controlled trials with relevance to the topic. The present review provides conclusions about the duration, frequency, and intensity of exercise appropriate for people living with cancer.

CONCLUSIONS

The evidence shows that exercise is safe and provides benefit in quality of life and in muscular and aerobic fitness for people with cancer both during and after treatment. The evidence is sufficient to support the promotion of exercise for adults with cancer, and some evidence supports the promotion of exercise in group or supervised settings and for a long period of time to improve quality of life and muscular and aerobic fitness. Exercise at moderate intensities could also be sustainable for longer periods and could encourage exercise to be continued over an individual's lifetime. It is important that a pre-screening assessment be conducted to evaluate the effects of disease, treatments, and comorbidities.

Hand Massage for Cancer Patients Undergoing Chemotherapy as Outpatients: A Pilot Study

CONTEXT

There are no studies on the effect of volunteer-provided hand massage in a busy chemotherapy outpatient practice.

OBJECTIVE

To assess the feasibility of introducing hand massage therapy into an outpatient chemotherapy unit and to evaluate the effect of the therapy on various symptoms experienced by cancer patients.

DESIGN

A pilot, quasi-experimental, pretest-posttest study.

SETTING

Chemotherapy outpatient clinic of a large tertiary care academic medical center.

PATIENTS/PARTICIPANTS

Forty chemotherapy outpatients.

INTERVENTION

After being approached by a trained volunteer from a hand massage team, patients consented to receive a 20-minute hand massage before chemotherapy that was individualized according to patient preference and expressed needs.

MAIN OUTCOME MEASURES

The visual analog scale (VAS) was used to measure pain, fatigue, anxiety, muscular discomfort, nervousness, stress, happiness, energy, relaxation, calmness, and emotional well-being (on a scale from 0-10) before and after the intervention; a satisfaction survey was administered after the therapy. Patients' demographic data were summarized with descriptive statistics, and VAS total scores were compared between groups at each time point with the two-group t test. Feasibility was evaluated from the number of patients who were approached, received a hand massage, and completed the study surveys.

RESULTS

Of the 40 participants, 19 were men (mean age, 59.5 years). Significant improvement after hand massage was indicated by VAS scores for fatigue, anxiety, muscular discomfort, nervousness, stress, happiness, energy, relaxation, calmness, and emotional well-being (P < .05). Pain scores also improved, but the difference was not statistically significant (P = .06). All patients indicated that they would recommend hand massage to other patients, and 37 were interested in receiving it during their next chemotherapy treatment.

Systematic Review of Occupational Therapy and Adult Cancer Rehabilitation: Part 1. Impact of Physical Activity and Symptom Management Interventions

This article is the first part of a systematic review of evidence for the effectiveness of cancer rehabilitation interventions within the scope of occupational therapy that address the activity and participation needs of adult cancer survivors. This article focuses on the importance of physical activity and symptom management. Strong evidence supports the use of exercise for cancer-related fatigue and indicates that lymphedema is not exacerbated by exercise. Moderate evidence supports the use of yoga to relieve anxiety and depression and indicates that exercise as a whole may contribute to a return to precancer levels of sexual activity. The results of this review support inclusion of occupational therapy in cancer rehabilitation and reveal a significant need for more research to explore ways occupational therapy can positively influence the outcomes of cancer survivors. Part 2 of the review also appears in this issue.

Occupational Therapy Interventions for Adults With Cancer

This Evidence Connection describes a case report of a man with non-Hodgkin's lymphoma who underwent an allogenic stem cell transplant. The occupational therapy assessment and treatment processes for an outpatient rehabilitation setting are described. Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's Evidence-Based Practice Project.

Psychosocial interventions for fatigue during cancer treatment with palliative intent

BACKGROUND

Fatigue is a prevalent and burdensome symptom for patients with incurable cancer receiving cancer treatment with palliative intent and is associated with reduced quality of life. Psychosocial interventions seem promising for management of fatigue among cancer patients.

OBJECTIVES

To assess the effects of psychosocial interventions for fatigue in adult patients with incurable cancer receiving cancer treatment with palliative intent.

SEARCH METHODS

We searched the following databases: CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, and seven clinical trial registries; we also searched the reference lists of articles. The date of our most recent search was 29 November 2016.

SELECTION CRITERIA

We included randomised controlled trials that compared psychosocial interventions in adults aged 18 years or over undergoing cancer treatment with palliative intent for incurable cancer versus usual care or other controls. Psychosocial interventions were defined as various kinds of interventions provided to influence or change cognitions, emotions, behaviours, social interactions, or a combination of these. Psychosocial interventions of interest to this review had to involve at least two interactions between the patient and the care provider in which the care provider gave the patient personal feedback concerning changes sought by these interventions. We included trials that reported fatigue as an outcome of interest.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data, including information on adverse events. We assessed the quality of evidence using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) and created a 'Summary of findings' table.

MAIN RESULTS

We identified 14 studies (16 reports) that met inclusion criteria for this review and involved 3077 randomised participants in total. Most of these studies included a mixed sample of participants; we obtained data for the subset of interest for this review (diagnosis of incurable cancer and receiving cancer treatment) from the study investigators of 12 studies, for which we included 535 participants in the subset meta-analysis for fatigue post intervention. Researchers investigated a broad range of psychosocial interventions with different intervention aims and durations. We identified sources of potential bias, including lack of description of methods of blinding and allocation concealment and inclusion of small study populations.Findings from our meta-analysis do not support the effectiveness of psychosocial interventions for reducing fatigue post intervention (standardised mean difference (SMD) -0.25, 95% confidence interval (CI) -0.50 to 0.00; not significant; 535 participants, 12 studies; very low-quality evidence). First follow-up findings on fatigue suggested benefit for participants assigned to the psychosocial intervention compared with control (SMD -0.66, 95% CI -1.00 to -0.32; 147 participants, four studies; very low-quality evidence), which was not sustained at second follow-up (SMD -0.41, 95% CI -1.12 to 0.30; not significant; very low-quality evidence).Results for our secondary outcomes revealed very low-quality evidence for the efficacy of psychosocial interventions in improving physical functioning post intervention (SMD 0.32, 95% CI 0.01 to 0.63; 307 participants, seven studies). These findings were not sustained at first follow-up (SMD 0.37, 95% CI -0.20 to 0.94; not significant; 122 participants, two studies; very low-quality evidence). Findings do not support the effectiveness of psychosocial interventions for improving social functioning (mean difference (MD) 4.16, 95% CI -11.20 to 19.53; not significant; 141 participants, four studies), role functioning (MD 3.49, 95% CI -12.78 to 19.76; not significant; 143 participants, four studies), emotional functioning (SMD -0.11, 95% CI -0.56 to 0.35; not significant; 115 participants, three studies), or cognitive functioning (MD -2.23, 95% CI -12.52 to 8.06; not significant; 86 participants, two studies) post intervention. Only three studies evaluated adverse events. These studies found no difference between the number of adverse events among participants in the intervention versus control group.Using GRADE, we considered the overall quality of evidence for our primary and secondary outcomes to be very low. Therefore, we have very little confidence in the effect estimate, and the true effect is likely to be substantially different from the estimate of effect. Limitations in study quality and imprecision due to sparse data resulted in downgrading of the quality of data. Additionally, most studies were at high risk of bias owing to their small sample size for the subset of patients with incurable cancer (fewer than 50 participants per arm), leading to uncertainty about effect estimates.

AUTHORS' CONCLUSIONS

We found little evidence around the benefits of psychosocial interventions provided to reduce fatigue in adult patients with incurable cancer receiving cancer treatment with palliative intent. Additional studies with larger samples are required to assess whether psychosocial interventions are beneficial for addressing fatigue in patients with incurable cancer.

Rehabilitation and exercise oncology program: translating research into a model of care

INTRODUCTION

The Rehabilitation and Exercise Oncology model of care (ActivOnco) was established to optimize cancer survivorship through exercise prescription and active lifestyle promotion, providing a transition of care from hospital to community. Patients having any cancer diagnosis, stage of disease, and treatment were eligible for evaluation and exercise prescription upon deterioration of performance status. The team of professionals included hospital-based physiotherapists proactively screening for rehabilitation needs, loss of functional independence, and exercise eligibility, plus exercise specialists in a community-based Wellness Centre to provide follow-up or direct access for post-treatment or non-complex patients.

METHODS

From January 2011 to December 2015, the hospital team assessed 1635 patients representing all major cancer sites, and the Wellness Centre team evaluated and prescribed exercise for 1066 participants. Primary interventions provided were education about fatigue management, physical activity promotion, exercise prescription, fracture risk reduction, referral to specialized follow-up services (for example, occupational therapy, lymphedema clinic), and coordination for mobility aids and paratransit services.

RESULTS AND CONCLUSIONS

Implementation of the ActivOnco model of care showed that exercise alone is not a panacea for all functional deterioration associated with the cancer trajectory and its treatment. However, screening to identify rehabilitation needs combined with exercise prescription can effectively improve the quality of survivorship in cancer patients. Program developments are limited by the cost of human resources, lack of hospital-based physical resources, and lack of public funding, all of which significantly limit the scope and development of appropriate services.

Exercise for people with cancer: a clinical practice guideline

BACKGROUND

Development of this guideline was undertaken by the Exercise for People with Cancer Guideline Development Group, a group organized by Cancer Care Ontario's Program in Evidence-Based Care (pebc). The purpose of the guideline was to provide guidance for clinicians with respect to exercise for patients living with cancer, focusing on the benefits of specific types of exercise, recommendations about screening requirements for new referrals, and safety concerns.

METHODS

Consistent with the pebc's standardized approach, a systematic search was conducted for existing guidelines, and systematic literature searches were performed in medline and embase for both systematic reviews and primary literature. Content and methodology experts performed an internal review, which was followed by an external review by targeted experts and intended users.

RESULTS

The search identified three guidelines, eighteen systematic reviews, and twenty-nine randomized controlled trials with relevance to the topic. The present guideline provides recommendations for the duration, frequency, and intensity of exercise appropriate for people living with cancer. It also provides recommendations for pre-exercise assessment, safety concerns, and delivery models.

CONCLUSIONS

There is sufficient evidence to show that exercise provides benefits in quality of life and muscular and aerobic fitness for people with cancer both during and after treatment, and that it does not cause harm. The present guideline is intended to support the Canadian Society for Exercise Physiology's Canadian physical activity guidelines. The recommendations are intended for clinicians and institutions treating cancer patients in Ontario, and for policymakers and program planners involved in the delivery of exercise programs for cancer patients.

Nursing Implications of Chemotherapy Agents and Their Associated Side Effects in Patients With Pancreatic Cancer

BACKGROUND

Survival for patients with advanced (locally advanced unresectable and metastatic disease) pancreatic cancer is very poor; however, several advances in treatment have been made during the past several years. Gemcitabine (Gemzar®)-based regimens, FOLFIRINOX, and nab-paclitaxel (Abraxane®)-based regimens have demonstrated efficacy in patients with advanced pancreatic cancer. Understanding the unique safety profile of each of these regimens is crucial in helping nurses identify symptoms, develop patient education strategies, and ultimately improve outcomes.

OBJECTIVES

This article aims to provide background information on and nursing implications of the treatment of patients with advanced pancreatic cancer by exploring the mechanism of action and efficacy and safety profiles of standard treatment regimens.

METHODS

Key trials of standard treatment regimens used in the treatment of advanced pancreatic cancer were examined with respect to efficacy outcomes and the most commonly observed adverse events. Symptom identification and management strategies are discussed from the nursing perspective.

FINDINGS

The current standard treatment options for patients with advanced pancreatic cancer have differences in efficacy and safety profiles. Nurses should educate themselves on these differences, particularly on associated adverse events and their management.

Nutrition therapy with high intensity interval training to improve prostate cancer-related fatigue in men on androgen deprivation therapy: a study protocol

Background

Cancer-related fatigue is one of the most prevalent, prolonged and distressing side effects of prostate cancer treatment with androgen deprivation therapy. Preliminary evidence suggests natural therapies such as nutrition therapy and structured exercise prescription can reduce symptoms of cancer-related fatigue. Men appear to change their habitual dietary patterns after prostate cancer diagnosis, yet prostate-specific dietary guidelines provide limited support for managing adverse side effects of treatment. The exercise literature has shown high intensity interval training can improve various aspects of health that are typically impaired with androgen deprivation therapy; however exercise at this intensity is yet to be conducted in men with prostate cancer. The purpose of this study is to examine the effects of nutrition therapy beyond the current healthy eating guidelines with high intensity interval training for managing cancer-related fatigue in men with prostate cancer treated with androgen deprivation therapy.

Methods/design

This is a two-arm randomized control trial of 116 men with prostate cancer and survivors treated with androgen deprivation therapy. Participants will be randomized to either the intervention group i.e. nutrition therapy and high intensity interval training, or usual care. The intervention group will receive 20 weeks of individualized nutrition therapy from an Accredited Practising Dietitian, and high intensity interval training (from weeks 12–20 of the intervention) from an Accredited Exercise Physiologist. The usual care group will maintain their standard treatment regimen over the 20 weeks. Both groups will undertake primary and secondary outcome testing at baseline, week 8, 12, and 20; testing includes questionnaires of fatigue and quality of life, objective measures of body composition, muscular strength, cardiorespiratory fitness, biomarkers for disease progression, as well as dietary analysis. The primary outcomes for this trial are measures of fatigue and quality of life.

Discussion

This study is the first of its kind to determine the efficacy of nutrition therapy above the healthy eating guidelines and high intensity interval training for alleviating prostate-cancer related fatigue. If successful, nutrition therapy and high intensity interval training may be proposed as an effective therapy for managing cancer-related fatigue and improving quality of life in men during and after prostate cancer treatment.

Impact of Different Exercise Programs on Severe Fatigue in Patients Undergoing Anticancer Treatment-A Randomized Controlled Trial

CONTEXT

Physical exercise can alleviate cancer-related fatigue. Randomized controlled trials in patients with advanced cancer are scarce.

OBJECTIVES

We test the impact of a structured, individual sports program on fatigue in patients with advanced cancer.

METHODS

Seventy-seven patients were invited to participate in this randomized controlled trial exploring the effects of physical exercises on fatigue 12 and 24 weeks after baseline. Patients were randomized into three groups. Group A received treatment as usual, Group B was taught a structured, individual sports program, and Group C received additional ambulatory physiotherapeutical supervision. Primary outcome was general fatigue, secondary outcomes included rate of severe general fatigue, further dimensions of the Multidimensional Fatigue Inventory (MFI), as well as walking distance.

RESULTS

Mean score of general fatigue as well as other MFI subdimensions differed nonsignificantly between all groups at 12 weeks. However, the mental fatigue score demonstrated a statistically significant difference between the three groups. The rate of severe general fatigue was significantly reduced within Intervention Group C. Significant longitudinal change of MFI-dimension mental fatigue was found and reached the threshold for minimal clinically important difference, while all MFI-dimensions increased in Group A.

CONCLUSION

Our results imply that tumor-patients' severe general fatigue can be reduced when patients conduct appropriate physical exercise. This study amends previous knowledge, as it describes the impact of outpatient physical exercise on fatigue in a heterogeneous patient cohort with various advanced cancer entities. Furthermore, this trial differentiates between patients with only a self-directed exercise program versus those receiving additional partially professional supervision.
