Exercise Recommendations for the Management of Symptoms Clusters Resulting From Cancer and Cancer Treatments

The Mechanisms Underlying the Beneficial Impact of Aerobic Training on Cancer-Related Fatigue: A Conceptual Review

Cancer-related fatigue (CRF) is a prevalent and persistent issue affecting cancer patients, with a broad impact on their quality of life even years after treatment completion. The precise mechanisms underlying CRF remain elusive, yet its multifaceted nature involves emotional, physical, and cognitive dimensions. The absence of effective medical treatments has prompted researchers to explore integrative models for potential insights. Notably, physical exercise emerges as a promising strategy for managing CRF and related symptoms, as studies showed a reduction in CRF ranging from 19% to 40%. Current recommendations highlight aerobic training at moderate intensity as beneficial, although questions about a dose-response relationship and the importance of exercise intensity persist. Despite the positive impact of exercise on CRF, the underlying mechanisms remain elusive. This review aims to provide a theoretical model explaining how aerobic exercise may alleviate CRF. Focusing on acute exercise effects, this review delves into the potential influence on peripheral and neural inflammation, immune function dysregulation, and neuroendocrine system disruptions. The objective is to enhance our understanding of the intricate relationship between exercise and CRF, ultimately paving the way for tailored interventions and potential pharmacological treatments for individuals unable to engage in physical exercise.

Effects of aquatic exercise program versus on-land exercise program on cancer-related fatigue, neuropathy, activity and participation, quality of life, and return to work for cancer patients: study protocol for a randomized controlled trial

BACKGROUND

Exercise has shown positive effects on fatigue, exhaustion, neuropathy, and quality of life in cancer patients. While on-land exercises have been studied, the aquatic environment offers unique advantages. Water's density and viscosity provide resistance, enhancing muscle strength, while hydrostatic pressure improves venous return. This trial aims to investigate the effect of aquatic exercises on time to return to work, work hours, work-related difficulties, daily life activity and participation, quality of life, exhaustion, fatigue, and neuropathy among cancer patients, compared to on-land exercise intervention group and a non-exercise group.

METHODS

This randomized controlled trial will include 150 cancer patients aged 18-65 years with stage III colon cancer or breast cancer patients with lymph node involvement. Participants in the aquatic exercise intervention group will undergo an 8-week, twice-weekly group-based Ai-Chi program, while the on-land exercise group will perform identical exercise. The control group will not engage in any exercise. The primary outcome will be assessed using an employment barriers questionnaire, capturing return to work date and working hours and daily life participation and activity and quality of life. Secondary outcomes include exhaustion, fatigue, and neuropathy. Data will be collected at baseline, post-intervention (8 weeks), and at 3,12, and 24 months. Mixed variance analyses will explore relationships among groups and over time for independent variables, with separate analyses for each dependent variable.

DISCUSSION

The potential benefits include an earlier return to work for patients, reducing their need for social and economic support. The study's implications on socio-economic policies are noteworthy, as a successful intervention could offer a cost-effective and non-invasive solution, improving patients' quality of life and increasing their participation in daily activities. This, in turn, could lead to a faster return to work, contributing to both personal well-being and broader societal interests by reducing reliance on social services.

TRIAL REGISTRATION

The trial is registered at ClinicalTrials.gov NCT05427344 (22 June 2022).

Symptom management in adult brain tumours: A literature review

AIM

To review the literature related to symptom management, clinical significance and related theoretical framework systems in adult patients with brain tumours.

BACKGROUND

As understanding of symptoms or symptom clusters and underlying biologic mechanisms has grown, it is apparent that symptom science is moving forward. Although some progress has been made in the symptom science of solid tumours such as breast and lung neoplasms, insufficient attention has been paid to symptom management for patients suffering from brain tumours. Further research is needed to achieve effective symptom management for these patients.

DESIGN

A literature review with a systematic search of symptom management in adult brain tumours.

METHODS

Electronic data bases were searched to obtain relevant published literature on symptom management in adults with brain tumours. This was then analysed and a synthesis of relevant findings is presented.

FINDINGS

Four significant general themes relating to symptom management of brain tumours in adults were identified: (1) The potential theoretical foundation related to symptom management was revealed. (2) Widely accepted validated scales or questionnaires for the assessment of single symptoms or symptom clusters were recommended. (3) Several symptom clusters and the underlying biologic mechanisms have been reported. (4) Specific symptom interventions for adults with brain tumours were collected and classified as evidence-based or insufficient evidence.

CONCLUSION

There are still many challenges in the effective management of symptoms in adults with brain tumours. The guiding role of theoretical frameworks or models related to symptom management should be utilized in future research. Using the concept of symptom clustering for research into symptoms found in patients with brain tumours, exploring common biological mechanisms for specific symptom clusters and making full use of modern big data resources to build a strong evidence base for an effective intervention or management program may inform the management of symptoms among these patients leading to better results.

NO PATIENT OR PUBLIC CONTRIBUTION

This is a literature review.

IMPLICATIONS FOR SYMPTOM MANAGEMENT

The ultimate goal is obviously not only improving the survival rate of patients with brain tumours, but also enhancing their quality of life. Several important findings from our review include the theoretical foundations, validated assessment tools, the assessment of symptom clusters and the underlying biologic mechanism, and the identification of the evidence base for symptom interventions. These are of relevance for managers, researchers and practitioners and may function as a reference to help the effective symptom management for adults with brain tumours.

Patterns of Concerns Among Hematological Cancer Survivors

BACKGROUND

Advances in treatment for hematological cancers warrant greater attention on survivorship concerns.

OBJECTIVE

The aims of this study were to describe survivorship concerns among hematological cancer survivors, identify subgroups of survivors with distinct classes of concerns, and examine sociodemographic and clinical differences across subgroups.

METHODS

We conducted a cross-sectional analysis of data from 1160 hematological cancer survivors, who rated their degree of concern regarding 20 physical, emotional, and practical changes. Clusters of concerns were identified using latent class analysis. Associations between respondent characteristics and cluster membership were calculated using multinomial logistic regression.

RESULTS

Survivors had a mean of 7.5 concerns (SD, 4.6; range, 0-19), the most frequent being fatigue/tiredness (85.4%); anxiety, stress, and worry about cancer returning (70.2%); and changes to concentration/memory (55.4%). Three distinct classes of concerns were identified: class 1 (low, 47.0%), characterized by low endorsement of most concerns, apart from fatigue; class 2 (moderate, 32.3%), characterized by high endorsement of a combination of concerns across domains; and class 3 (high, 20.7%), characterized by the highest number of concerns out of the 3 identified classes, including greater endorsement of concerns relating to sexual well-being. Class membership was differentiated by survivor age, sex, marital status, and diagnosis.

CONCLUSIONS

Three distinct patterns of concerns were detected in a large sample of hematological cancer survivors. Patterns of concerns could be differentiated by survivor characteristics.

IMPLICATIONS FOR PRACTICE

Our study highlights the concerns experienced by hematological cancer survivors and provides support for a tailored biopsychosocial approach to survivorship care in this context.

Sleep-wake Disturbance following Allogeneic Hematopoietic Stem Cell Transplantation: Trajectory and Correlates.. [DOI: 10.21203/rs.3.rs-2055018/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Adults undergoing allogeneic hematopoietic stem-cell transplant (HSCT) experience progressive physical and psychosocial distress in early stages post-HSCT, including sleep-wake disturbance (SWD), psychological distress, and fatigue. We conducted a longitudinal feasibility study to determine severity/trajectory of SWDs and investigated relationships among actigraphic sleep parameters, sleepiness, insomnia severity, fear of cancer recurrence (FCR), anxiety, depression, and fatigue at 100 (T1), 150 (T2), and 180 days (T3) post-HSCT. Eight adults enrolled. Median total sleep time (TST) at T1–T3 days was adequate (7.24, 7.17, and 7.09 hours), but sleep efficiency (SE) was suboptimal (78.9%, 78.5%, 83.67%). Median Epworth Sleepiness Scale (ESS) and Insomnia Severity Index (ISI) scores indicated minimal drowsiness and subclinical insomnia at T1–T3. Median FCR Inventory (FCRI) scores indicate diminishing FCR over time. Median scores across time for anxiety (48.05, 50.2, and 44.1) and depression (44.9, 41, and 41) suggest moderate–mild distress with slight fluctuations. Surprisingly, fatigue scores increased from T1–T3 (46, 50.9, and 52.1). Increases in ISI and FCRI scores were associated with modest increases in anxiety. Findings suggest the need to evaluate and address sleep, psychological distress, and fatigue in HSCT recipients. Larger studies to confirm prevalence of SWD and association with psychological factors are warranted.

Synergistic Interactions Among Fatigue, Sleep Disturbance, and Depression in Women With Breast Cancer: A Cross-Sectional Study

OBJECTIVES

To assess the symptom cluster of fatigue, sleep disturbance, and depression among female patients with breast cancer receiving chemotherapy, and to evaluate its impact on quality of life (QOL) and symptom severity.

SAMPLE & SETTING

372 patients receiving adjuvant chemotherapy recruited from two tertiary hospitals in China.

METHODS & VARIABLES

Symptom severity and QOL were evaluated using the Brief Fatigue Inventory, Pittsburgh Sleep Quality Index, Patient Health Questionnaire-9, and Functional Assessment of Cancer Therapy-Breast on the eighth day after receiving chemotherapy.

RESULTS

All symptoms positively correlated with each other. Although the symptom cluster was significantly associated with decreased QOL, individualized symptom severity worsened as the number of symptoms increased.

IMPLICATIONS FOR NURSING

The prevalence of and interactions among fatigue, sleep disturbance, and depression negatively affect symptom severity and patients' QOL. Conducting early assessment followed by effective cluster-based interventions is needed to manage this symptom cluster.

Integrative oncology: Addressing the global challenges of cancer prevention and treatment

The increase in cancer incidence and mortality is challenging current cancer care delivery globally, disproportionally affecting low- and middle-income countries (LMICs) when it comes to receiving evidence-based cancer prevention, treatment, and palliative and survivorship care. Patients in LMICs often rely on traditional, complementary, and integrative medicine (TCIM) that is more familiar, less costly, and widely available. However, spheres of influence and tensions between conventional medicine and TCIM can further disrupt efforts in evidence-based cancer care. Integrative oncology provides a framework to research and integrate safe, effective TCIM alongside conventional cancer treatment and can help bridge health care gaps in delivering evidence-informed, patient-centered care. This growing field uses lifestyle modifications, mind and body therapies (eg, acupuncture, massage, meditation, and yoga), and natural products to improve symptom management and quality of life among patients with cancer. On the basis of this review of the global challenges of cancer control and the current status of integrative oncology, the authors recommend: 1) educating and integrating TCIM providers into the cancer control workforce to promote risk reduction and culturally salient healthy life styles; 2) developing and testing TCIM interventions to address cancer symptoms or treatment-related adverse effects (eg, pain, insomnia, fatigue); and 3) disseminating and implementing evidence-based TCIM interventions as part of comprehensive palliative and survivorship care so patients from all cultures can live with or beyond cancer with respect, dignity, and vitality. With conventional medicine and TCIM united under a cohesive framework, integrative oncology may provide citizens of the world with access to safe, effective, evidence-informed, and culturally sensitive cancer care.

The Successful Return-To-Work Questionnaire for Cancer Survivors (I-RTW_CS): Development, Validity and Reproducibility

Background

Cancer survivors’ perspectives on a successful return to work (RTW) may not be captured in the common measure of RTW, namely time until RTW.

Objective

The purpose of this study was therefore to develop an RTW outcome measure that reflects employed cancer survivors’ perspectives, with items that could be influenced by an employer, i.e. the Successful Return-To-Work questionnaire for Cancer Survivors (I-RTW_CS), and to assess its construct validity and reproducibility.

Methods

First, three focus groups with cancer survivors (n = 14) were organized to generate issues that may constitute successful RTW. Second, a two-round Delphi study among 108 cancer survivors was conducted to select the most important issues. Construct validity of the I-RTW_CS was assessed using correlations with a single-item measure of successful RTW and the Quality of Working Life Questionnaire for Cancer Survivors (QWLQ-CS; n = 57). Reproducibility (test–retest reliability) was assessed using the intraclass correlation coefficient (ICC; n = 50).

Results

Forty-eight issues were generated, of which seven were included: ‘enjoyment in work’; ‘work without affecting health’; ‘confidence of employer without assumptions about work ability’; ‘open communication with employer’; ‘feeling welcome at work’; ‘good work–life balance’; and ‘joint satisfaction with the situation (employer and cancer survivor)’. Correlations with single-item successful RTW and QWLQ-CS were 0.58 and 0.85, respectively. The reproducibility showed an ICC of 0.72.

Conclusions

The I-RTW_CS provides an RTW outcome measure that includes cancer survivors’ perspectives and weights its items on an individual basis, allowing a more meaningful evaluation of cancer survivors’ RTW. This study provides preliminary evidence for its construct validity and reproducibility.

Longitudinal symptom burden in adult patients with acute leukaemia participating in the PACE-AL randomised controlled exercise trial-an explorative analysis

OBJECTIVE

Patients with acute leukaemia undergoing chemotherapy experience multiple symptoms that interfere with activities of daily living. Exercise-based interventions have been used to remedy disease and treatment-related symptoms in patients with cancer. We explored the impact of exercise and health counselling on symptom prevalence, severity and longitudinal patterns.

METHODS

Explorative analysis of M.D. Anderson Symptom Inventory and Brief Fatigue Inventory completed weekly in a randomized controlled trial of patients with acute leukaemia undergoing consolidation chemotherapy. Seventy patients were consecutively recruited and randomly allocated to usual care (n = 36) or 12-week supervised exercise and health counselling (n = 34) at Copenhagen University Hospital, 2011-2014.

RESULTS

There was no difference in symptom prevalence between groups, but we found a significant increase in symptom and fatigue severity in the intervention group during the study period. However, the symptom burden reduced significantly in both groups at 12 weeks. Longitudinally, the symptom cluster; 'drowsiness, fatigue, disturbed sleep, difficulty remembering' was significantly more severe in the intervention group.

CONCLUSION

Intervention and control group participants had substantial symptom and fatigue burden during 12-week moderate exercise and health counselling in patients with acute leukaemia undergoing chemotherapy. A greater symptom burden was found in the intervention group during the 12 weeks, though reducing in both groups at 12 weeks. Studies are needed to examine the link between exercise and symptom severity.

Exercise Barriers and Adherence to Recommendations in Patients With Cancer

PURPOSE

The American College of Sports Medicine exercise guidelines for cancer survivors encourage a combination of 150 minutes of moderate-intensity aerobic activity and 2-3 weekly sessions of strength training. Cancer survivors often experience more barriers to meeting recommended guidelines because of side effects from cancer treatments. Our aim was to measure the cancer survivors' adherence and barriers with these recommendations.

METHODS

Two hundred adult cancer survivors completed surveys (Stanford Patient Education Research Center Exercise Behaviors Survey and an exercise barrier scale) reporting their physical activity, barriers to physical activity, and symptom assessment.

RESULTS

A total of 68/200 participants (34%) reported adhering to the recommended physical activity guidelines of 150 minutes or more per week. Those who adhered to the guidelines reported fewer barriers to exercise (mean of 2.44 compared with 4.15 barriers, P < .0001). Female participants (P = .01), higher number of barriers, and feeling of poor well-being were less likely to report at least 60 or 150 minutes of exercise time. Lack of interest (P = .003) and self-discipline (P = .001) were reported as barriers. These participants were more likely to report high symptom burden of pain (P = .007) and fatigue (P = .005). Participants who reported < 60 minutes of exercise reported lack of enjoyment (P = .03), lack of equipment (P = .01), and symptoms of poor appetite, poor well-being, and increased dyspnea.

CONCLUSION

Although recommendations are given for exercise, adherence to recommendations is low. Issues of motivation, including lack of interest and self-discipline, and symptoms of pain and fatigue were some of the main reported barriers to adhering to the recommended exercise guidelines. Therefore, interventions aimed at increasing motivation and treating symptoms could improve cancer survivor adherence to recommended exercise guidelines.

EEG Correlates of Central Origin of Cancer-Related Fatigue

The neurophysiological mechanism of cancer-related fatigue (CRF) remains poorly understood. EEG was examined during a sustained submaximal contraction (SC) task to further understand our prior research findings of greater central contribution to early fatigue during SC in CRF. Advanced cancer patients and matched healthy controls performed an elbow flexor SC until task failure while undergoing neuromuscular testing and EEG recording. EEG power changes over left and right sensorimotor cortices were analyzed and correlated with brief fatigue inventory (BFI) score and evoked muscle force, a measure of central fatigue. Brain electrical activity changes during the SC differed in CRF from healthy subjects mainly in the theta (4-8 Hz) and beta (12-30 Hz) bands in the contralateral (to the fatigued limb) hemisphere; changes were correlated with the evoked force. Also, the gamma band (30-50 Hz) power decrease during the SC did not return to baseline after 2 min of rest in CRF, an effect correlated with BFI score. In conclusion, altered brain electrical activity during a fatigue task in patients is associated with central fatigue during SC or fatigue symptoms, suggesting its potential contribution to CRF during motor performance. This information should guide the development and use of rehabilitative interventions that target the central nervous system to maximize function recovery.

Online Interventions to Improve Mental Health of Pediatric, Adolescent, and Young Adult Cancer Survivors: A Systematic Review and Meta-Analysis

Objective: Over the last 10 years, online interventions to improve mental health have increased significantly. This study's primary objective was to determine the effectiveness of online interventions in improving the mental health of pediatric, adolescent, and young adult (PAYA) cancer survivors. The secondary objective was to identify the independent variables associated with online intervention efficacy for mental health improvement. Methods: On June 25-30, 2021, we searched the Medline, PsycINFO, EMBASE, and Cochrane databases for eligible English language publications that reported randomized controlled trials of online interventions aimed at improving mental health among PAYA cancer survivors. The results were analyzed using a systematic review and a three-level meta-analysis. Results: Thirteen studies met the inclusion criteria. In six (42%) studies, the intervention focused on physical activity enhancement, while ten (77%) studies used self-directed interventions. Online interventions were more efficacious, compared to control conditions, in improving sleep g = 0.35 (95% CI 0.04-0.66) and psychological well-being g = 0.32 (95% CI 0.09-0.56), but not for reducing the symptoms of depression g = 0.17 (95% CI -0.13 to 0.47), anxiety g = 0.05 (95% CI -0.15 to 0.25), and pain g = 0.13 (95% CI -0.13 to 0.39). Conclusion: Online interventions were generally effective in improving mental health in PAYA cancer survivors, although negative results were found in some critical outcomes. More high-quality evidence is needed for definite conclusions to be drawn. The study protocol was registered in PROSPERO (CRD42021266276).

The Feasibility and Effects of Qigong Intervention (Mind-Body Exercise) in Cancer Patients With Insomnia: A Pilot Qualitative Study

Background:

Up to 80% of cancer patients experience insomnia that significantly affects their quality of life. This pilot qualitative study investigated the feasibility and effects of a 3-week Qigong (mind-body exercise) intervention with a 1-week follow-up in cancer patients experiencing insomnia.

Methods:

Cancer patients with insomnia who had completed radiotherapy or chemotherapy treatment and/or were at least 8 weeks post-cancer-related surgery were recruited. Primary outcomes were feasibility outcomes, which included recruitment, retention, attendance, completion of assessment, adverse events and participant feedback via a questionnaire and focus group/individual interview. Secondary outcomes on insomnia severity and sleep quality were measured using the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI) at baseline, mid, post-intervention and follow-up.

Results:

Seven participants were recruited and two withdrew from the study. The participant retention rate was 71.4% with an overall attendance rate of more than 84% and participants were able to complete all required assessments. An adverse event relating to the worsening of existing musculoskeletal condition was reported. Qualitative analysis of participant feedback identified 4 emerging themes: (1) experience from Qigong intervention; (2) class preferences; (3) barriers to participation; and (4) recommendation for improvement. Participants reported increased relaxation, improved sleep and energy level, better upper body flexibility and reduced stress. Both ISI and PSQI scores improved significantly (P < .05).

Conclusion:

This study demonstrated that it is feasible to employ the current clinical trial design using Qigong intervention on insomnia in cancer patients. Preliminary data suggest that the intervention may improve sleep outcomes, however, these findings need to be confirmed by future robust randomized controlled trials.

Trial registration:

The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12618001670268) http://www.ANZCTR.org.au/ACTRN12618001670268.aspxon10October2018.

The role of physical activity in cancer survivors' quality of life

PURPOSE

As a result of a cancer diagnosis and treatment, many cancer survivors experience persistent physical, mental, and emotional symptoms that affect their quality of life. Physical activity has been identified as an intervention that may help to manage the side effects of a cancer diagnosis and its treatment. The purpose of this study was to investigate the role of physical activity on overall quality of life in adult cancer survivors.

METHODS

One-on-one semi-structured interviews were conducted in person or via telephone with 13 adult (≥18 yrs) cancer survivors who had completed cancer treatment.

RESULTS

These cancer survivors described their physical activity as improving their physical functioning and mental health, as a means of positive social engagement, and adding positivity to their daily life.

CONCLUSION

Even though the cancer survivors in this study experienced diverse types of cancer and for different lengths of time as well as varying methods of treatment(s), these results support the role of physical activity in enhancing cancer survivors' quality of life. Further research is warranted to (a) expand this research with a larger sample and quantitative methods, (b) examine healthcare providers' knowledge and application of exercise guidelines to cancer survivors in cancer care, and (c) explore implementation strategies for greater advocacy for healthcare providers to share the exercise recommendations with cancer survivors.

Relationships of exercise timing with sleep, fatigue and rest-activity rhythms of lung cancer patients in Taiwan: An exploratory study

OBJECTIVE

To explore the relationship of exercise timing (exercising close to bedtime, exercising in daylight and maintaining fixed exercise schedule) with sleep quality, fatigue and rest-activity rhythms among lung cancer patients in Taiwan.

METHODS

Results from 43 lung cancer patients who were assigned and adhered to the exercise intervention in a 12-week randomised controlled trial were analysed. The MD Anderson Symptom Inventory and Pittsburgh Sleep Quality Index (PSQI) were administered. Actigraphs were used to assess rest-activity rhythms (in-bed less than out-of-bed dichotomy index, I < O) and objective sleep parameters, including total sleep time (TST) and sleep onset latency (SOL).

RESULTS

Patients who exercised >4 hr before bedtime had significant improvement in fatigue (p < .0001), sleep quality (p = .012 for PSQI; p = .037 for TST; p = .017 for SOL) and rest-activity rhythms (p = .048 for I < O). Furthermore, patients who exercised with daylight exposure had a significant improvement in fatigue (p = .037) and sleep quality (p = .039 for PSQI).

CONCLUSIONS

Exercising >4 hr before bedtime with daylight exposure is associated with improvement in rest-activity rhythms, sleep quality and fatigue in lung cancer patients. The causal relationship requires further investigation with experimental design.

The experience of cancer-related fatigue, exercise and exercise adherence among women breast cancer survivors: Insights from focus group interviews

AIMS AND OBJECTIVES

To identify the experience of breast cancer survivors regarding cancer-related fatigue, exercise and exercise adherence.

BACKGROUND

Cancer-related fatigue is a common symptom among cancer survivors that limits quality of life. Despite exercise being recommended as a viable solution to manage cancer-related fatigue, relatively few research studies on the experience of cancer-related fatigue and exercise adherence have been conducted.

DESIGN

This was a qualitative study to identify breast cancer survivors' experience of cancer-related fatigue, exercise and exercise adherence. This paper adhered to the COREQ checklist in reporting.

METHODS

Four focus group interviews were conducted with 16 breast cancer survivors who had fatigue score of 4 out of 10 (moderate fatigue) or greater. Ethical approval was obtained and participants met for focus group interview discussion. The interview guide included questions on cancer-related fatigue, barriers and facilitators of exercising, strategies for exercise adherence and suggestions for a supportive programme.

RESULTS

Four themes were identified through thematic analysis: (a) The insidious and overpowering nature of cancer-related fatigue; (b) exercising when experiencing fatigue surrounded by prevailing myths; (c) multiple barriers to exercise; and (d) facilitative factors to continue exercising despite fatigue.

CONCLUSIONS

Participants' experience of moderate or greater cancer-related fatigue prevented them from exercising, despite knowing its importance, and limited them to passive activities. Misconceptions that exercise is associated with lymphedema and risk of recurrence, poor psychosocial self-image and lack of clear knowledge and exercise programmes for cancer survivors further limited adherence to exercise. In contrast, finding comfort and strength through exercising and interacting with other breast cancer survivors were facilitative factors.

RELEVANCE TO CLINICAL PRACTICE

The insights shared by breast cancer survivors experiencing cancer-related fatigue can contribute to developing an exercise adherence programme as a way to manage and alleviate fatigue and establish healthy survivorship care.

Effect of a mixed-exercise program on physical capacity and sedentary behavior in older adults during cancer treatments

BACKGROUND

Aging, cancer and its treatment all contribute to increase the risk of deconditioning and sedentary behaviors. Mixed exercise is recognized to counteract the effects of aging and deconditioning as well as improving physical capacity during cancer treatment in adults.

AIMS

To determine the impact of a mixed exercise program (MXEP) to improve physical capacity and decrease sedentary behavior time (SBT) in older adults during cancer treatment.

METHODS

Fourteen participants (68.8 ± 3.4 years) completed 12 weeks of a mixed exercise program (MEXP) (n = 6) or stretching (n = 8) while they were under cancer treatment. Five tests of the Senior Fitness Test (Chair Stand, 8-Foot Up & Go, Arm Curl, Sit & Reach, 6 min Walk Test), two maximal strength tests (leg press and handgrip) and a Global Physical Capacity Score (GPCS) were used to assess physical capacity. For the amount of SBT (min/day), we used question 1 of the Physical Activity Scale for the Elderly.

RESULTS

Both groups presented significant pre- vs post-intervention differences for the Chair Stand, Arm Curl, 6 min Walk Tests and also GPCS. Nevertheless, this difference was significantly greater in the MEXP group only for the Chair Stand Test (4.3 ± 2.2 vs 1.0 ± 1.3 reps; p = 0.01) and the GPCS (4.0 ± 0.6 vs 1.5 ± 2.3 points; p = 0.047). A tend to display a greater decrease in SBT (- 295 ± 241 min/week vs - 11 ± 290 min/week; p = 0.079) was observed in favor of MEXP.

CONCLUSION

A 12-week mixed exercise program led to significant improvements in physical capacity and may reduce SBT.

Symptom-based interventions to promote quality survivorship

Survival alone is no longer an adequate outcome for persons with brain tumors; the quality of the survivorship experience should be viewed with equal importance. Symptom management is a significant component of quality survivorship care. Regardless of their histology, brain tumors and therapies used to treat them produce symptoms that affect an individual's ability to function in everyday life. Common symptoms include fatigue, cognitive impairment, distress, and sleep disturbance. Symptom-based interventions for persons with brain tumors focus on prevention, self-management, and prescriptive interventions targeted to these problems. Unfortunately, little evidence exists to support many interventions, making it challenging for clinicians to provide concrete recommendations. Research is needed to provide evidence in support of symptom-based interventions while novel approaches to these challenging problems are developed.

Effects of Aerobic and Resistance Exercises on Physical Symptoms in Cancer Patients: A Meta-analysis

Objective. This study aimed to conduct a meta-analysis to establish the effect of exercise interventions on physical symptoms, including fatigue, nausea/vomiting, pain, dyspnea, insomnia, loss of appetite, constipation, and diarrhea in cancer patients and survivors. Methods. We searched articles published before April 2017 using the following databases: Cochrane Library, PubMed/MEDLINE, CINAHL, Scopus, PEDro, Health & Medical Collection, and Psychology Database. Randomized controlled trials (RCTs) of exercise intervention in cancer patients, which evaluated cancer-related physical symptoms using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30, were included. Symptom scale data were extracted for meta-analysis. Subgroup analyses were performed for exercise types (aerobic, resistance, and mixed exercise programs). Results. Of the 659 articles, 10 RCTs were included in the meta-analysis, of which the mean PEDro score was 5.43 (SD = 1.28). Fatigue, pain, dyspnea, and insomnia were significantly lower in the intervention group than in the control group at postintervention in cancer patients. However, exercise intervention did not promote or suppress nausea/vomiting, loss of appetite, constipation, and diarrhea in cancer patients. The effect of exercise type on each symptom was not different. Conclusion. Exercise intervention was confirmed to improve fatigue, pain, and insomnia and might have reduced dyspnea in cancer patients. However, the benefits of exercise on nausea/vomiting, loss of appetite, constipation, and diarrhea were not shown in any exercise type. Further research is warranted to examine the effects of exercise interventions on physical symptoms in cancer patients.

Exercise medicine for advanced prostate cancer

PURPOSE OF REVIEW

Exercise is a provocative medicine, known for its preventive, complimentary and rehabilitative role in the management of cancer. Impressively, exercise is also emerging as a synergistic and targeted medicine to enhance symptom control, modulate tumour biology and delay disease progression, with the potential to increase overall survival. Given the complex clinical presentation of advanced prostate cancer patients and their omnipresent comorbidities, this review describes the current and potential role of exercise medicine in advanced prostate cancer.

RECENT FINDINGS

Exercise has been shown to be safe, feasible and effective for advanced prostate cancer patients, inclusive of patients with bone metastases; a previously excluded population due to patient and clinician fear of adverse events. Preclinical data provide insight into the ability of exercise to modulate cancer-specific outcomes, may synergistically increase the potency of chemotherapy and radiotherapy and may endogenously and/or mechanically suppress tumour formation, growth and invasion in visceral and skeletal tissue. Epidemiological studies have also shown an association between physical activity and increased survival.

SUMMARY

Exercise oncology is rapidly evolving, with impressive possibilities that may directly improve patient outcomes in advanced prostate cancer. Research must focus on translating preclinical trials into human clinical trials and investigate the direct effect of exercise on overall survival.

Conclusiones: los pacientes con cáncer experimentan múltiples síntomas de forma simultánea durante las distintas fases de la enfermedad. Es incipiente el estudio de este fenómeno, los retos para la enfermería se centran en la generación de respuestas que alivien la carga de los grupos de síntomas y mejoren la calidad de vida de estos pacientes. Es necesario validar escalas de carga del síntoma y explorar los grupos de síntomas incluyendo variables clínicas ligadas a los tratamientos oncológicos.

Lifestyle interventions are feasible in patients with colorectal cancer with potential short-term health benefits: a systematic review

PURPOSE

Lifestyle interventions have been proposed to improve cancer survivorship in patients with colorectal cancer (CRC), but with treatment pathways becoming increasingly multi-modal and prolonged, opportunities for interventions may be limited. This systematic review assessed the evidence for the feasibility of performing lifestyle interventions in CRC patients and evaluated any short- and long-term health benefits.

METHODS

Using PRISMA Guidelines, selected keywords identified randomised controlled studies (RCTs) of lifestyle interventions [smoking, alcohol, physical activity (PA) and diet/excess body weight] in CRC patients. These electronic databases were searched in June 2015: Dynamed, Cochrane Database, OVID MEDLINE, OVID EMBASE, and PEDro.

RESULTS

Fourteen RCTs were identified: PA RCTs (n = 10) consisted mainly of telephone-prompted walking or cycling interventions of varied durations, predominately in adjuvant setting; dietary/excess weight interventions RCTs (n = 4) focused on low-fat and/or high-fibre diets within a multi-modal lifestyle intervention. There were no reported RCTs in smoking or alcohol cessation/reduction. PA and/or dietary/excess weight interventions reported variable recruitment rates, but good adherence and retention/follow-up rates, leading to short-term improvements in dietary quality, physical, psychological and quality-of-life parameters. Only one study assessed long-term follow-up, finding significantly improved cancer-specific survival after dietary intervention.

CONCLUSIONS

This is the first systematic review on lifestyle interventions in patients with CRC finding these interventions to be feasible with improvements in short-term health. Future work should focus on defining the optimal type of intervention (type, duration, timing and intensity) that not only leads to improved short-term outcomes but also assesses long-term survival.
