Exercise is physical activity that involves repetitive bodily movement done to improve or maintain one or more of the components of physical fitness: cardiorespiratory endurance (aerobic fitness), muscular strength, muscular endurance, flexibility, and body composition. Exercise interventions in patients with cancer have been provided as home-based, patient self-managed programs as well as supervised and unsupervised individual or group exercise sessions of varying duration and frequency. They can include combinations of aerobic and resistance activities. Exercise has been studied in patients with cancer for anxiety, chemotherapy-induced nausea and vomiting, depression, dyspnea, hot flashes, lymphedema, sleep/wake disturbance, pain, and fatigue. It has also been studied for caregiver strain and burden. Users of this information are encouraged to review intervention details in study summaries, as the exercise interventions studied and their timings in the trajectory of cancer care vary and these differences can influence effectiveness.

PHASE OF CARE: Multiple phases of care
Overall, the effect size for walking on sleep disturbance was -0.52 (Hedges' g: 95%; CI -0.79, -0.25). There was significant overall heterogeneity among the studies. Multiple subgroup analyses were conducted to explore factors that may contribute to the heterogeneity. The effect size was not associated with age, gender, the duration of the intervention, or adherence rate. An analysis demonstrated no evidence of publication bias. Studies were done before, during, or after treatment for cancer, and the overall effect sizes did not differ according to the timing of the intervention. All studies used walking of moderate intensity, and most studies were done in women with breast cancer. Some studies included additional exercise interventions such as strength training, and some also included psychoeducational interventions.
Walking exercise appears to improve sleep in patients with cancer.
There was a relatively small number of studies included with high heterogeneity. Twelve studies were excluded because they did not report sufficient data to compute an effect size or they did not use a self-reported sleep outcome. These excluded studies, which have been summarized in other PEP® summaries, did not demonstrate the effectiveness of exercise. This suggests that effectiveness may be overestimated in this analysis.
This analysis provides some support for moderate intensity walking exercise to improve sleep. The findings need to be viewed with caution because of the high heterogeneity of the studies and the contrary findings that were excluded from this analysis. However, walking is a safe activity for patients, and it can be suggested to patients as an approach that may improve sleep. It also could be incorporated into multicomponent approaches to address sleep-wake disturbances.

To synthesize findings from intervention studies for sleep disturbance in patients with cancer and their caregivers.
Databases searched were PubMed, CINAHL, and PsycINFO.
Search keywords were sleep, sleep disturbance, insomnia, intervention, cancer, oncology, and caregivers.
Studies dated through 2010 that evaluated sleep disturbance/sleep quality as the primary or secondary outcome were included.
Intervention groupings analyzed via meta-analysis included cognitive-behavioral therapy (CBT), education, exercise, and complementary and alternative therapies. Effect sizes appeared to be slightly over 1.0 for CBT, close to 0 for education, slightly over 1.0 for exercise, and slightly over 0 for complementary and alternative therapies. Specific effect sizes were only shown graphically, and actual data were not presented. No separate analysis of caregiver effects could be determined. Modes of delivery of interventions varied widely across studies.
Findings suggest at least moderate effects of CBT and exercise for improvement in sleep disturbances for patients with cancer. No substantial effects of exercise and education were demonstrated.
The review was limited by the lack of any data regarding heterogeneity in the meta-analysis, variability of interventions, and modes of delivery to enable any firm conclusions.
Insufficient evidence was provided to draw any conclusions regarding intervention effects for caregivers.

STUDY PURPOSE: To summarize the available evidence regarding the extent to which exercise improves sleep in patients with cancer
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Multiple phases of care
Sleep outcomes improved in 10 studies (47.6%). Interventions included home-based programs, supervised exercise, or a combination of these two approaches. Aerobic and resistance exercise were employed individually or in combination. Meta-analysis of 12 randomized, controlled trials showed no significant effect of interventions compared to control groups.
Analysis showed no clear significant effects of exercise interventions on sleep outcomes among patients with cancer.
Evidence from this analysis does not show an effect of exercise interventions on sleep quality. However, a large body of evidence regarding numerous other benefits of exercise for people with cancer exists. The analysis and most research have included patients who do not necessarily have clinical insomnia, so it would not be expected that interventions would improve sleep. Future research needs to be conducted among patients with clinically relevant insomnia.

To conduct a meta-analysis of the effectiveness of exercise interventions on health-related quality of life (HRQoL) and domains (e.g., physical, psychological, economic, social, and spiritual well-being) of HRQoL among adult cancer survivors posttreatment.
Databases searched were Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, PEDro, LILACS, SIGLE, SPORTDiscus, OTSeeker, Sociological Abstracts, Web of Science, and Scopus.
Search keywords (selected from appendices) were exercise, quality of life, health-related quality of life, pain, and cancer.
Studies were included in the review if they
Studies were excluded if they reported patients with terminal cancer or in hospice care who were receiving active treatment for primary or recurrent cancer.
A total of 1,795 relevant references were retrieved. A total of 1,636 articles were excluded based on the title and abstract. After further review of the abstract, 82 were excluded because they did not meet the inclusion criteria. An additional 13 were excluded from qualitative synthesis because they were ongoing studies.
The review has clinical applicability for late effects and survivorship.
Exercise had a positive effect on change in HRQoL scores at 12 weeks and six months of evaluation, and it improved cancer-specific HRQoL in breast cancer concerns. The effect on HRQoL remained after exclusion of patients who were receiving active treatment. For cancer-specific HRQoL, there was significant improvement in exercise groups compared with controls for breast cancer concerns at baseline to 12 weeks and six months. There was a significant decrease in anxiety in the exercise group compared to controls at 12 weeks only (standardized mean difference [SMD] = -0.26; 95% confidence interval [CI] [-0.44, -0.07]) but not in breast cancer-only analysis. There was a high risk of bias in most of these studies, and when these were removed, the results were not significant. Significant differences were noted in body image at follow-up (12 weeks to six months and beyond) using the Rosenberg Self-Esteem Scale. Significant change scores were noted for cancers other than breast for improving depression scores (SMD = -0.46; 95% CI [-0.72, -0.19]). Significant improvements were noted in emotional well being (12 weeks) and fatigue (12 weeks and 6 months) (SMD = -0.42; 95% CI [-0.83, -0.02]). No effects after six months were seen for fatigue, and effects were not significant when studies involving patients during treatment were excluded. Improvement in pain using follow-up scores (12 weeks) was seen (SMD = -0.29; 95% CI [-0.55, -0.04]), but this was from a single trial. Positive effects were noted in sexuality scores at six months and sleep disturbance at 12 weeks (sleep SMD = -0.46; 95% CI [-0.72, -0.20]). Significant improvements were noted in change scores for social functioning (12 weeks and six months). No significant changes were noted in cognitive function, general health perspective, role function, and spirituality in exercise trials.
Exercise interventions showed beneficial effects on HRQoL and some HRQoL domains, including breast cancer concerns, body image, emotional well being, sexuality, sleep disturbances, social functioning, anxiety, fatigue, and pain at various follow-up time points.
Findings supported the general benefit of exercise for patients with cancer; however, there is further need for research to verify the positive effects of exercise on symptoms of cancer in various patient groups and at various phases of cancer care. These future research studies should determine how to produce larger effect sizes over time and delineate predictors of that effect, such as type of exercise, intensity of the program, timing, and type of cancer and treatment in order to maximize the effect on QoL. It will be important to note that certain questionnaires can affect the outcomes, and consistency would improve this body of research.

STUDY PURPOSE: To determine the effects of nonpharmacologic interventions on sleep quality in patients with lung cancer
TYPE OF STUDY: Meta-analysis and systematic review
DATABASES USED: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, WHO International Clinical Trials Registry Platform Search Portal and Clinical Trials.gov
YEARS INCLUDED: Open start date through December 2016
INCLUSION CRITERIA: Nonpharmacologic intervention studies of any design for patients with lung cancer at any stage or illness and at any point in treatment, compromising at least 25% of participants who used sleep disturbance or quality as primary or secondary outcome by subjective or objective measure
EXCLUSION CRITERIA: None noted
TOTAL REFERENCES RETRIEVED: N = 1,259
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Two authors reviewed all studies for eligibility, and disagreements were resolved through discussion and third author as needed.
FINAL NUMBER STUDIES INCLUDED: N = 22
TOTAL PATIENTS INCLUDED IN REVIEW: 1,272
SAMPLE RANGE ACROSS STUDIES: ≤ 10 = 3 studies, > 10 < 100 = 16 studies , ≥ 100 = 3 studies
KEY SAMPLE CHARACTERISTICS: 82.4% of participants had lung cancer, > 66% had stage III or IV illness and were undergoing treatment.
PHASE OF CARE: Multiple phases of care
Interventions were grouped into 3 categories. Standard exercise and rehabilitation programs showed statistically significant improvements in sleep outcome measures in the short-term follow-up period (SMD -0.43, 95% CI; -0.68, -0.19, p = 0.0005). No differences were seen at the medium- and longer-term follow-up periods. Information, psychoeducation, and symptom screening interventions showed significant differences when compared to control at short-term follow up but was not measured at a later interval (SMD: -0.87, 95% CI, -1.21, -0.54, p, 0.00001). Mind-body interventions (2 studies with n < 100) showed large effect in treating sleep disturbances in patients with lung cancer in the short-term follow-up period (SMD: -0.88, 95% CI, -1.59, -0.16, p = 0.02), which were not observed at the medium follow-up period.
Although the three groups of interventions, exercise, information, psychoeducation, and mind-body interventions appear to improve sleep disturbances in the short term following the interventions, the data quality is low. The series of 22 studies looks at multiple interventions per category, some with small sample sizes, and uses a variety of delivery methods. Based on individual assessments and results of studies in other cancer populations, nurses may want to recommend the interventions to patients with lung cancer, at least to try. However, the call for ongoing research in the area continues, with specific focus on larger sample sizes, specific disease states, and single interventions.
The data for recommending use of nonpharmacologic interventions for sleep disturbances in patients with lung cancer are not sufficient. It is clear that they are feasible and may be effective in some instances. It does appear that they may improve sleep disturbance in the short term, but further work is needed to conduct larger studies and examine individual interventions and their components, as well as the treatment phase for the patient in which the intervention in applied. Based on assessment of patient condition and desire, nurses can use their judgment to make recommendations for patients with lung cancer to try nonpharmacologic interventions to improve sleep.

To determine baseline sleep characteristics of endometrial cancer survivors, the impact of demographic and treatment characteristics on sleep quality, the association of sleep quality with quality of life and stress levels, and the impact of physical activities on sleep.
Individualized exercise prescriptions based on baseline function. Adherence to the American College of Sports Medicine Guidelines requiring 30 minutes of moderate exercise five or more days per week or at least 20 minutes of rigorous exercise three or more days per week with telephone-based counseling sessions, printed materials, and pedometers. Decreasing frequency of counseling telephone calls from weekly to twice monthly to monthly over six months.
Secondary analysis of Steps to Health, a single-arm cohort study.
Sleep quality measured with the Pittsburgh Sleep Quality Index (PSQI). Physical activity measured with the Community Health Activities Model Program for Seniors (CHAMPS). Quality of life (QOL) measured with the SF-36.
At baseline, 61% of the sample had poor sleep quality (PSQI > 5). Obese survivors were more likely to have sleep disturbances than were their normal-weight counterparts (p = 0.029). At baseline, poor sleepers had higher stress levels than good sleepers (p = 0.002). Poor sleep quality was associated with lower health-related QOL: vitality (p = 0.001), bodily pain (p = 0.004), general health (p = 0.002), social functioning (p = 0.005), role limitations caused by emotional problems (p = 0.005), mental health (p = 0.002), and the mental component score (p = 0.003). Sleep quality improved in cancer survivors who increased their weekly total physical activity or moderate-vigorous intensity physical activities (MPVA) throughout the intervention (p = 0.004 and 0.05, respectively). Adjusting for covariates (e.g., age, time since diagnosis, obesity status, disease stage, treatment), improvement in sleep quality was associated with increased hours of total activity (p = 0.026).
Poor sleep quality was common in endometrial cancer survivors and an increase in physical activity was associated with improved sleep quality.
Sleep problems are common in women following treatment for endometrial cancer and are associated with stress and poor QOL. Increasing physical activity may improve sleep quality for these women.

To determine the dose-response effect of aerobic exercise on health-related quality of life outcomes among colon cancer survivors after treatment completion, including functional status, sleep, fatigue, fear of recurrence, and bowel function.
The intervention was a prescription for home-based aerobic exercise over six months–either low-dose aerobic exercise (150 minutes per week) or high-dose aerobic exercise (300 minutes per week). Each participant received a treadmill and a heart rate monitor. An exercise physiologist provided ongoing in-person, telephone, and email support, individualized to each participant, and monitored adherence to the exercise protocol. Exercise intensity was prescribed at 50%-70% of age-predicted maximum heart rate and gradually increased for each participant to meet their goal.
PHASE OF CARE: Transition phase after active treatment
Randomized controlled trial with three groups: usual care (usual recommendations for activity), low-dose aerobic exercise (150 minutes per week), and high-dose aerobic exercise (300 minutes per week).
Medical Outcomes Survey Short Form (SF-36), Functional Assessment of Cancer Therapy–Colorectal (FACT-C), Pittsburgh Sleep Quality Index (PSQI), Fear of Cancer Recurrence Inventory (FCRI), Fatigue Symptom Inventory (FSI), North Central Cancer Treatment Group questionnaire (bowel function)
Physical health score in SF-36 improved by 1.2 (d = 0.08) in the low-dose group and 13.1 (d = 0.58) in the high-dose group. FACT-C scores increased by 7.6 (d = 0.49) in the low-dose group and 6.8 (d = 0.58) in the high-dose group. PSQI scores decreased by 0.3 in the low-dose group (d = -0.11) and by 1.1 (d = -0.3) in the high-dose group. PSQI subscales of sleep quality and sleep latency showed improvement. FSI scores increased by 0.8 (d = 0.08) in the low-dose group and decreased by 6 (d = -0.75) in the high-dose group. There were no changes observed in mental health scores of SF-36, FCRI scores, or bowel function scores.
The six-month home-based aerobic exercise intervention for survivors of colon cancer improved health-related outcomes, including physical function, quality of life, sleep quality, and fatigue. Improvements were dose-related, such that a higher dose of aerobic exercise resulted in greater improvement in outcomes.
Moderate intensity aerobic exercise in excess of the recommended 150 minutes per week showed clinically meaningful improvements in health-related outcomes, including physical function, quality of life, sleep quality, and fatigue in survivors of colon cancer who have completed treatment.

To assess the effects of a 12-week walking program on improving subjective and objective sleep quality and rest-activity rhythms in patients with lung cancer
Home-based walking exercise at moderate intensity and weekly exercise counseling were provided. Participants were given detailed instruction according to a manual for the exercise program, including determination of intensity, pulse monitoring, rating perceived exertion, prevention of injury, and conditions requiring termination of the exercise program. Weekly exercise-related phone counseling was provided to reinforce teaching and encourage continued participation. The usual care control group was given typical services and asked to maintain normal activity and not perform additional exercise. Exercise counseling was offered to the usual care group at the end of the study. An actigraph was worn by patients to collect data continuously for 72 hours.
PHASE OF CARE: Multiple phases of care
Randomized, controlled trial
Overall participants completed 58.2% of all planned exercise sessions. The usual care group showed a higher mean amount of moderate physical activity at all time points when measured (37–46 minutes per day compared to 38–10 minutes per day at three and six months). No significant difference over time was reported between groups. The walking exercise group had improved PSQI scores over time compared to the usual care group (p = 0.001). No differences between groups in objective measures of sleep quality existed, except that total sleep time at six months was higher in the exercise group (p = 0.023).
Sleep quality measures showed improvement in the study group compared to the controls; however, given that the average amount of moderate intensity exercise was higher in the control group, the impact of walking exercise versus counseling is unclear.
The effect of exercise on sleep quality in patients with insomnia remains unclear from this study. Although measures showed improvement in the walking exercise group compared to the controls, the amount of moderate intensity exercise was actually higher in the control group. This does not point to the impact of exercise on differences seen in this study.

A home-based exercise program to improve function, fatigue, and sleep quality in patients with stage IV lung and colorectal cancer: A randomized controlled trial. Journal of Pain and Symptom Management, 45, 811–821.
To report the effects of a strength training and walking program in patients with stage IV lung and colorectal cancer.
Patients were given usual care or 1.5 hours of training by a physical therapist on rapid, easy, strength training exercises (REST) and pedometer-based walking using an instruction manual, resistance bands, an exertion rating scale, and a study log. They were then followed bimonthly by telephone for eight weeks.
Patients were undergoing the end of life phase of care.
The study was a single-blinded, randomized, controlled trial.
Mobility, fatigue, and sleep measures were statistically significant between the intervention and control groups from baseline to week 8 (p = 0.002, p = 0.03, and p = 0.002, respectively), in favor of exercise. Other measures did not show significance. The number of REST sessions and weeks logged with step counts were associated with changes in the mobility score. Survival and withdrawals did not differ significantly between the groups.
A home-based intervention using walking and strength exercises may improve mobility, fatigue, and sleep quality in patients with stage IV colorectal or lung cancer.
The teaching of walking exercises and strength routines may improve functioning in this patient population in terms of mobility, sleep quality, and fatigue. The one-time education session may be appealing to nurses looking for a timely intervention to help improve these symptoms.

A home-based exercise program was used that included aerobic and resistance training. The exercise group received an individualized exercise prescription, with strength levels and aerobic capacity at first testing. The control group received usual care. Outcomes were exercise, fatigue, mood, and sleep.
Patients were undergoing the active treatment phase of care.

To compare usual care with a home-based individualized exercise program (HBIEP) in patients receiving intensive treatment for multiple myeloma (MM) and epoetin alfa therapy.
This was a randomized trial with repeated measures of two groups (one experimental and one control) and an approximate 15-week experimental period for the HBIEP. The control group received a recommendation to walk 20 minutes three times per week. In the HBIEP, patients were given color-coded stretch bands and materials to illustrate exercises to be used, and they were to perform aerobic walking to reach 65% to 80% of the maximal heart rate. Patients mailed in weekly activity summaries. Assessments were performed at baseline, 10 to 12 weeks later prior to the second chemotherapy cycle, and three to four weeks later when finishing stem cell collection.
This was a randomized, controlled trial with repeated measures of two groups and a 15-week experimental period.
No statistically significant differences existed among the experimental and control groups for fatigue, sleep, or performance (aerobic capacity). Statistically significant differences (p < 0.05) were found in each of the study outcomes for all patients as treatment progressed, and patients experienced more fatigue and poorer nighttime sleep and performance.
The effect of exercise seemed to be minimal on decreasing fatigue, improving sleep, and improving performance. Exercise is safe and has physiologic benefits for patients undergoing MM treatment and, when combined with epoetin alfa, helped to alleviate anemia.
Although the results might indicate no derived benefit, patients became more fatigued, slept less, and experienced a decline in performance with more treatment. The HBIEP group required fewer red blood cell transfusions to maintain a similar hemoglobin level, less platelet transfusions, and fewer days to collect stem cells. When combined with epoetin alfa therapy, exercise had an effect in decreasing cancer-related anemia and improving cell count recovery after high-dose chemotherapy. These are benefits to patients and the healthcare economy. Cancer rehabilitation exercises may result in improved performance. Having fatigue prior to treatment might predict having fatigue after treatment. Energy conservation measures should be considered with endurance and resistance exercises. Rehabiltation therapy might be needed for deconditioned patients. Exercise should be tailored individually based on the patient's disease stage, presence of bone lesions, and values. The HBIEP may have helped to alleviate anemia, but there is no evidence that HBIEP combining muscle strengthening and aerobic walking exercises decreases fatigue.

To compare the effects and doses of a three-arm exercise trial to improve sleep quality in patients with breast cancer receiving active chemotherapy
The three-group design of the CARE trial compared the standard dose of 25–30 minutes of aerobic exercise (STAN) to higher doses of activity that included 50–60 minutes of aerobic exercise (HIGH) and 50–60 minutes of combined-dose of aerobic and resistance exercise (aerobic and strength training three times per week) (COMB). COMB strength training was part of the 50–60 minute session and included two sets of 10–12 repetitions of nine different strength exercises at 60%–75% of the estimated one-repetition max (RM). All groups received three weekly treatments with outcomes measures to determine primary and secondary outcomes. Interventions continued for the duration of chemotherapy. Data were collected at baseline, midpoint 1, midpoint 2, and postintervention.
Blinded, randomized, controlled trial
296 patients completed the study with complete data. Baseline global sleep scores were M = 6.2 (SD = 4.1) with 52% of participants reporting poor sleep at baseline (PSQI > 5). The main effects of the study showed that the HIGH group had statistically better outcomes compared to the STAN group for primary sleep global scores (d = 0.22; p = 0.039), sleep quality (d = 0.26; p = 0.028), and sleep latency (d = 0.18; p = 0.049). The COMB group barely scored significantly higher than the STAN group for global sleep quality, sleep duration, and sleep efficiency (d = 0.24; p = 0.04) and percent of poor sleepers (d = 0.20; p = 0.045). The HIGH group was statistically better than COMB for sleep latency only (d = 0.20; p = 0.04) . Significant moderators included surgery, baseline aerobic fitness, baseline aerobic exercise guidelines, baseline strength guidelines, and number of comorbid conditions. The effect size for the HIGH group compared to the STAN group was larger for global sleep quality for lumpectomy patients with no comorbid conditions, those meeting aerobic exercise guidelines, and those who were fitter at baseline. Scores in the COMB group were higher than those of the STAN group for lumpectomy patients meeting strength exercise guidelines. The overall effect for each arm was small.
Higher doses of exercise and the combination of exercise and strength training were associated with better overall sleep quality compared to the standard dose of 50–60 minutes of aerobic exercise. Different sleep components appeared to be most affected by the type of exercise intervention, and no single intervention impacted all the sleep components measured.
Nurses often suggest maintaining activity during treatment, but there is little information about the effectiveness of this recommendation on sleep-wake disturbances. This study provided a large sample of patients with breast cancer that narrowed down the doses needed to affect sleep. The overall results of this study suggest that exercise can improve sleep during chemotherapy treatment. However, the limitations of this study need to be taken into consideration before recommending the actual interventions used.

To test the hypothesis that aerobic exercise would be better than usual care for improving sleep quality, and to examine potential moderators of intervention effects
Patients were stratified by lymphoma type and whether the patient was receiving chemotherapy and then randomized to receive the exercise intervention or usual care. The intervention consisted of supervised aerobic sessions three days per week for 12 weeks. Prescriptions for unsupervised exercise were provided for patients who were unable or unwilling to attend supervised sessions, and these sessions were not counted in adherence evaluation. Usual care patients were asked to not change baseline exercise habits and were offered supervised exercise after final study assessments.
Aerobic exercise resulted in a small (d = -0.19) but not significant improvement in global sleep quality. In the intervention group, the exercise program improved global sleep quality in patients receiving chemotherapy (p = .013), but not for those who were off therapy. Exercise improved global sleep quality in those who were poor sleepers at baseline (p = .007), but not in those who were good sleepers at baseline. Analysis further showed that positive effects of exercise were seen in patients with shorter time since diagnosis, patients who were obese, and patients who had less aggressive disease.
Aerobic exercise did not significantly improve sleep quality in this study of patients with lymphoma. Exercise appeared to have some benefits for sleep quality in individuals who were in active treatment.
Findings show that overall, participation in aerobic exercise does not improve overall sleep quality in patients with lymphoma. Some benefit may exist for patients during chemotherapy treatment and for individuals who have baseline poor sleep quality. For these types of patients, nurses should consider suggesting aerobic exercise or providing exercise prescriptions.

Determine the effectiveness of an intensive intervention (i.e., two weeks at a SPA centre involving exercise, physiotherapy, and dietary education) on overall quality of life, weight, nutrition, and physical activity in women who recently had completed treatment for non-metastatic breast cancer
The intervention included a two-week stay at a SPA centre with a daily routine of physical training (i.e., two hours daily under the supervision of a physiotherapist, which included walking, strength training, and aquaexercise), dietary education with cooking lessons and provision of healthy meals, and aesthetic care, massage, etc. Dietary consultations every six months for three years also were incorporated into standard follow-up care.
PHASE OF CARE: Transition phase after active treatment
Prospective, randomized, repeated measures (baseline, 6, 12, 18, and 24 months after intervention) two-group clinical trial
Statistically significant differences were seen between groups on the SF-36 measure at six months, but these differences did not persist in any dimension at year one except for a difference in vitality at one year between groups. Although data were collected on weight/body mass index, diet, and sleep, results for these variables are not reported (except to note no significant differences in sleep between the groups). The plots/trends in quality of life over time (at 6, 12, 18, and 24 months) look very similar for both groups, except for a significant upward trend at six months for the intervention group. The correlation was stronger between HADS depression and SF-36 quality of life. In the SPA group, an overall decrease was seen in anxiety compared to baseline scores (p = 0.0005). No significant difference was seen in the anxiety scores between the SPA and control groups at six months. Depression decreased in both groups but to a greater degree in the SPA group. A significant difference was seen between the SPA group and control group in terms of depression scores. What the “control” or comparison group was or what care was given to them is not clear.
As reported, patients with non-metastatic breast cancer did not appear to derive significant benefit (improved quality of life as measured by the SF-36) from a two-week SPA intervention in terms of improving quality of life and reducing anxiety and depression.
This unrealistic intervention (two-week SPA stay) does not seem sustainable. Furthermore, if this “intensive” intervention did not demonstrate significant impact on quality of life or anxiety, except for depression, then the “cost” of such an intensive intervention is not worth the benefit. When exactly the intervention occurred is not reported relative to timing of completion of breast cancer treatment except to say “within nine months,” but this is an important variable/covariate because time since treatment completion (and intervention) might impact study results. Importantly, unclear is how subjects were screened or that only a “distressed” group was enrolled. The report that global SF-36 scores at study inclusion were 56 and 54 respectively (treatment and control groups) indicates that this is not a very “stressed” group, as evidenced by SF-36. The higher the scores on the SF-36, the better the quality of life. These scores at study inclusion are right at the midpoint range of 0%–100%; thus, a possible floor effect is at play. Overall, this is not a very well developed or reported study.
No real meaningful nursing implications are drawn from this study. The intervention seems unrealistic and unsustainable and did not impact outcome measures as predicted, except for depression.

A self-paced, progressive, home-based exercise program (walking exercise versus usual care) was used. Individualized walking was based on age, level of fitness, and history of exercise. The program was a brisk, incremental, 20- to 30-minute walk, followed by a 5-minute slow walking cool-down, four to five times per week for six weeks. Outcomes were exercise, fatigue, physical functioning, emotional distress, and sleep.
Patients were undergoing the active treatment phase of care.
The study used a two-group, controlled, pre-/posttest experimental design.
Women who exercised regularly reported less difficulty sleeping than the control group.
Caution: maintain safety while exercising.

To test the feasibility and provide a preliminary evaluation of the effects of an exercise program for fatigue, sleep disturbance, mood, and symptoms in patients with cancer
Participants randomly were assigned to the treatment or control group. Patients in the control group received usual care, an educational booklet and DVD, and weekly telephone calls. Patients in the experimental group received initial one-on-one training sessions and were given exercise program kits containing written instructions, a pedometer, and an exercise log. Patients were to choose activities that provided low to moderate intensity exercise and perform these daily for at least 20 minutes. Participants also were asked to walk three to five days per week. Weekly phone calls to the experimental group were made to monitor participation and make adjustments to the walking prescription as needed. The program was planned for 12 weeks.
Randomized, controlled trial
Patients in the experimental group demonstrated a nonsignificant improvement in fatigue (d = -0.48). There were no significant group by time effects for other measures. Data were not collected after week 10 because of loss of subject follow-up.
The findings of this study support the known effect of exercise on cancer-related fatigue; however, the small sample in this study limits the strength of these findings.
This study provides minimal additional support for the benefits of exercise among women with breast cancer during active treatment. Exercise has been shown to be effective in reducing multiple symptoms, and nurses should encourage patients to be active.

To determine if a home-based walking program is more effective than usual care in reducing fatigue, sleep disturbances, and symptoms of depression in older women receiving hormone treatment for breast cancer.
Patients were recruited from breast cancer clinics and randomized to usual care or a prescribed exercise program that focused on walking. Researchers followed patients' progress over a 14-week period. Patients completed study instruments at baseline, two weeks later via mail, 12 weeks after baseline at a clinic visit, and 14 weeks after baseline via mail. Cortisol, serotonin, interleukin-6 (IL-6), and bilirubin were collected at the initial clinic visit and again at three months. At visit 1 and at 12 weeks, patients were asked to wear a sleep-watch actigraph for 72 continuous hours. The walking exercise intervention was a moderate walking activity for 20 minutes, four times a week. Patients were to log the duration and frequency of walking activity.
The study was a longitudinal, repeated-measures, randomized, clinical trial.
Levels of fatigue over time and between groups were not significantly different. PSQI scores decreased significantly over time in the exercise group (p = 0.007) and did not change in the usual care control. Actigraphy analysis after 12 weeks showed a shorter wake time (p = 0.02), sleep time (p = 0.05), and less movement during sleep (p = 0.002) in the exercise group. There was no difference between groups in regard to sleep efficiency, which is the ratio of total sleep time to time in bed. There were no differences in cortisol levels over time or between groups. ANOVA showed a significant difference between groups and across time in serotonin levels, with an intervention effect of exercise (p = 0.009). There were no differences between groups or over time in regard to symptoms of depression.
A home-based walking intervention appears to be acceptable to older women receiving hormone therapy for breast cancer and an intervention that is feasible for use in that population. Decline in PSQI scores in the exercise group suggest that this type of intervention may help improve sleep quality in this population. Effects of the exercise intervention on biomarkers are unclear.
An exercise program involving walking may be helpful to patients receiving hormone treatment for breast cancer, but the actual effects of such a program on fatigue, sleep, and symptoms of depression are unclear.
Rabin, C., Pinto, B., Dunsiger, S., Nash, J., & Trask, P. (2009). Exercise and relaxation intervention for breast cancer survivors: feasibility, acceptability and effects. Psycho-Oncology, 18, 258–266.
To assess the feasibility, acceptability, and preliminary effects of a 12-week combined physical activity and relaxation intervention for sedentary, early stage breast cancer survivors after completing all primary treatment.
Early stage breast cancer survivors participated in a 12-week combined physical activity (PA) and relaxation intervention, with baseline and 12- and 24-week assessments. Participants received a theoretically grounded intervention modeled after on the “Moving Forward” intervention based on the principles of the transtheoretical model (TTM) and the social cognitive theory (SCT). Participants were instructed to do moderate-intensity level exercise with pre-/post stretching. The goal was to walk 30 minutes five times a week by the twelfth week of the intervention. The relaxation component included instruction on progressive muscle relaxation (PMR); a CD with PMR instructions was included. Participants were telephoned weekly to provide counseling, a review of their practice activities, reinforcement, identification of barriers, and negation of the next week's goals.
The study used a prospective, single-arm, repeated measures design.
Participant evaluations of the intervention indicated that it was feasible and acceptable (e.g., 100% would recommend it to others); objective data further supported its feasibility (e.g., 83% completed the trial, and 91% of the intervention calls were received). In addition, when comparing 12- and 24-week follow-up data to baseline data, participants demonstrated significantly increased PA, improved mood and sleep quality, and reduced fatigue (p < 0.05).
The pilot study suggested that the intervention is feasible, acceptable, and produces promising effects on mood, sleep, and fatigue.
Multibehavior interventions, such as exercise and relaxation, hold promise for cancer survivors and may improve quality of life (i.e., fatigue, sleep, mood, and disturbance).

To determine the effectiveness and safety of a disseminated community-based exercise program for cancer survivors who completed cancer treatment.
Twice weekly over a period of 12 weeks, YMCA personal trainers supervised groups of seven to 14 study participants during 90-minute exercise sessions at 13 YMCA sites. Study measures were administered at baseline and after the 12-week exercise program. The standardized protocol included aerobic warm-up (10 minutes), resistance training (50 minutes), and community building time (e.g., sharing personal experiences, didactic and experiential training in breathing, relaxation, stress management, and nutrition). Precautions or contraindicated movements were noted for each participant, and resistance training was individualized. YMCA personal trainers had at least one year of personal training experience and received a specialized 16-hour group training by a cancer rehabilitation physical therapist. Additional training to address emotional issues for participants and trainers was provided by a licensed clinical psychologist with expertise in cancer survivorship. Participants and immediate family received access to YMCA facility branches and were encouraged to exercise outside of the sessions.
Patients were undergoing long-term follow-up postcancer treatment.
This was a prospective pre/post (nonrandomized) study design.
Validated patient-reported outcomes measures included
The study indicated that the community-based exercise program has important beneficial effects on physiologic, symptom, and quality of life health outcomes for cancer survivors and is safe to implement. Findings suggested that the program is helpful for improving fatigue, insomnia, physical function, overall musculoskeletal symptoms, mental health, social support, and physical activity in cancer survivors. Average baseline insomnia ratings of 1.63 (SD = 0.93) differed significantly from postintervention ratings of 1.43 (SD = 0.85) (p < 0.001). Additionally, the exercise program indicated notable improvements in physiologic measures (blood pressure, upper and lower body strength, walking endurance, and flexibility).
Community-based exercise groups for cancer survivors of mixed diagnoses and ages, who have completed active treatment, have physiologic and psychosocial benefits and appear to be safe. Because the participants self-selected to be part of the study and were screened for their ability to participate, findings cannot be generalized to the larger cancer survivor population.
Survivors may benefit from participating in a community-based exercise program tailored to meet their individual needs as a survivor; however, exercise programs should be preceded by consultation with health care providers. Additional nursing research is needed to determine the effect of resistance training and other exercise protocols in more diverse cancer survivor populations.

To examine mediators of fatigue effects of an exercise intervention
Patients were randomized to an exercise intervention or control group. The intervention combined walking and strength training with resistance bands. Walking was gradually increased by week 9 to 40 minute sessions of moderate intensity, four times per week, and participants attended 26 individual exercise sessions supervised by an exercise specialist. Resistance training was two times per week in the last 10 weeks of the study with the supervised aerobic walking sessions. Resistance was advanced as tolerated. Six group meetings with a psychologist also were provided every other week to provide support and improve exercise adherence. The control group was instructed to maintain usual exercise behavior.
Adherence to supervised exercise sessions was 91%–93%. Exercise goals for at home were met in 65% of the weeks during the study. General fatigue declined significantly in the intervention group compared to controls (d = –0.49, p < .01). Fatigue interference (d = –0.38, NS) declined in the intervention group. Fatigue intensity increased in the intervention group and declined in controls (d = 0.3, NS). There were no significant differences in depression. Anxiety declined in the intervention group (d = –0.54, p < .05). Sleep/wake dysfunction declined in both groups over time, but more in the intervention group (d = –0.054, p < .01). Positive effects in fatigue intensity were significantly mediated by IL-6, IL-10, IL-6:IL-10, and TNF alpha:IL-10.
The exercise program used here showed a small to medium non-significant effect on fatigue intensity and interference, as measured in this study. Effects of exercise on fatigue were mediated by some cytokine system responses.
Although this study has limitations, findings do provide additional support for positive effects of exercise on cancer-related fatigue among cancer survivors. Findings here show evidence of potential effects through the cytokine system. Adherence to the exercise program in this study was very good, using a support group interaction and the combination of supervised exercise sessions and home-based exercise recommendations. This type of additional support may help many patients adhere to an exercise program.

The purpose was to determine the effects of a physical activity behavior change intervention compared to usual care on sleep quality in post-primary treatment breast cancer (BC) survivors.
Participants were randomized to a three-month, social cognitive theory-based Better Exercise Adherence after Treatment for Cancer (BEAT Cancer) behavior change intervention or usual care. BEAT Cancer included 12 supervised exercise sessions with exercise specialists during the first six weeks, followed by unsupervised home-based exercise supported by counseling sessions with exercise specialists every two weeks. Participants also completed 6 group discussion sessions with topics about exercise barriers and benefits, goal setting, behavioral modification, safety, relapse prevention, and exercise role models. The goal of BEAT Cancer was to complete ≥ 150 minutes of moderate-to-vigorous physical activity each week. Study measures were completed at three time points: baseline, immediately postintervention (month 3), and 3 months postintervention (month 6).
PHASE OF CARE: Transition (postprimary treatment, could be on hormonal therapy)
Randomized controlled intervention trial with usual care control
The BEAT Cancer intervention significantly improved PSQI global sleep quality when compared with usual care at postintervention (mean between-group difference [M] = -1.4; 95% CI = -2.1 to -0.7; p < 0.001) and 3 months postintervention (M = -1.0; 95% CI = -1.7 to -0.2; P = .01), after adjusting for covariates. BEAT Cancer improved several PSQI subscales at postintervention (sleep quality M = -0.3; 95% CI = -0.4 to -0.1; p = 0.002; sleep disturbances M = -0.2; 95% CI = -0.3 to -0.03; p = 0.016; daytime dysfunction M = -0.2; 95% CI = -0.4 to -0.02; p = 0.027) but not 3 months postintervention. A nonsignificant increase in the percentage of participants classified as good sleepers was reported. No significant between-group difference was noted for accelerometer sleep latency or efficiency.
A social cognitive theory-based physical activity intervention reduced perceived global sleep disturbance at postintervention and 3 months postintervention compared to usual care, primarily related to improvements in various aspects of sleep quality. However, improvements were not detected with accelerometer.
Exercise adherence intervention may reduce perceived global sleep disturbance at 3 and 6 months postintervention. Additional exercise research in oncology is needed to optimize the use of physical activity in improving the health and well-being of cancer survivors through improved sleep.

To assess the effect of home-based exercise on sleep quality and proinflammatory cytokines in patients with breast and prostate cancer receiving radiation therapy
Patients randomly were assigned to the home-based exercise or control group. Patients in the control group received standard care and were encouraged to remain only as active as they were prior to study inclusion. Patients in the intervention group were given 45 minutes of instruction by an exercise physiologist and given an exercise kit that contained written instructions, a pedometer, and resistance bands. The exercise prescription followed the American College of Sports Medicine guidelines for progressive walking at moderate intensity. Resistance band use was designed for low to moderate intensity, focusing on upper extremities. Patients wore pedometers during the first week. All patients were followed weekly for four weeks. Study measures were obtained at baseline and after the intervention.
Fifteen of the 19 patients in the exercise group reported increased daily steps walked and at follow-up at three months walked significantly more than patients in the control group (p < .05). Twelve of the 19 patients in the intervention group reported doing resistance training for an average of 17 minutes three days per week. Overall sleep quality improved over time in both groups, and no significant difference was seen between groups. Post-intervention levels of IL-6 and TNF-α increased slightly in both groups. Both of these were lower in the exercise group, but the difference was not significant.
These findings do not demonstrate an impact of a home-based exercise program on sleep quality.
Findings show that patients being provided with training and materials to do a home-based exercise program was associated with good adherence by patients. However, findings did not show an effect of this exercise on sleep quality. Exercise is beneficial and should be encouraged but does not appear to have a beneficial effect on sleep-wake disturbance.

The study goals were to (a) identify determinants of sleep disturbances in patients with breast cancer (BC) before radiotherapy, (b) determine the trajectory of sleep disturbances during radiotherapy and at 12-month follow-up, and (c) assess whether an exercise intervention could affect sleep trajectories.
The exercise intervention consisted of eight progressive resistance exercises (3 sets, 8–12 repetitions at 60%–80% of one repetition maximum). The relaxation control group did progressive muscle relaxation according to the Jacobson method. Both interventions were supervised and performed over approximately one hour twice weekly for 12 weeks along with other patients with cancer.
PHASE OF CARE: Active antitumor treatment
Prospective randomized controlled intervention trial with attention control (relaxation) and healthy control
Higher prevalence of sleep disturbances were observed among patients with BC who had previous chemotherapy, higher BMI and depressive symptoms, previous hysterectomy, degenerative diseases, thyroid disorders, and higher symptom burden (hot flashes, pain, breast or arm problems, dyspnea). Patients with BC experienced higher levels of sleep disturbance at all times, but the trajectory of sleep disturbances in exercising women was similar to healthy women. The exercise intervention significantly decreased sleep disturbances compared to the relaxation control group on a 0–100 scale (between-group mean differences of -10.2; p = 0.03) from baseline to the end of radiotherapy and -10.9 (p = 0.005) to the end of the intervention). Sleep disturbances decreased in the exercise group and increased in the control group. At 12 months, differences were observed but not statistically significant (mean difference = -5.9, p = 0.20) even after adjusting for potential confounders.
This exercise intervention trial supports the findings of smaller studies that radiotherapy worsens sleep disturbances in patients with BC compared to healthy women. Findings suggest that a 12-week resistance training during radiotherapy can have positive effects on sleep disturbances during the treatment phase and even months after treatment completion.
Sleep quality is associated with quality of life in patients with cancer. These findings about determinants of sleep disturbance, the course sleep disturbance during radiotherapy, and the effect of an exercise intervention are of significance to many patients with BC.

To evaluate the effects of a supervised outpatient physical therapy strengthening and conditioning program on symptoms and quality of life
The program included aerobic exercise and strength training. The first two sessions were individualized under the supervision of a physical therapist. Patients who needed additional assistance walking, transferring, or using equipment continued to attend one-hour individual sessions. Patients were placed into 90-minute group sessions. The program consisted of intensive work for eight weeks, then six months of maintenance training was offered for those who were interested. Study assessments were done at baseline and after eight weeks.
Quasi-experimental
The results of the 6MWt were better on average at the end of eight weeks (p < 0.0001). Physical component scores on the SF-36 improved (p < 0.001) as did mental component scores after eight weeks (p < 0.005). At the end of six months, only physical component scores remained higher than reported at baseline. Fatigue (p = 0.003) and dyspnea (p = 0.007) were improved at eight weeks. After six months, fatigue (p = 0.0077), shortness of breath (p = 0.0005), and disturbed sleep (p = 0.045) were improved from baseline. Patients still in active treatment showed significantly less improvement. Those who showed the worst performance at baseline showed the greatest improvement.
The eight-week strengthening and conditioning program improved physical function, fatigue, dyspnea, and sleep disturbance in this study. Improvement was greatest among those who had the worst symptoms and physical performance statuses at baseline and among those who were not in active treatment.
The findings of this study demonstrated the effectiveness of an exercise program on symptoms of fatigue, shortness of breath, and sleep disturbance among a variety of patients with cancer. These findings add to the large body of evidence about the efficacy of exercise.
Tang, M. F., Liou, T. H., & Lin, C. C. (2010). Improving sleep quality for cancer patients: benefits of a home-based exercise intervention. Supportive Care in Cancer, 18, 1329–1339.
To determine the effect of a home-based walking exercise program on the sleep quality and quality of life (QOL) of cancer patients and to determine if enhanced sleep quality was associated with improvement in QOL over time.
Patients were recruited from oncology outpatient clinics in two university-based medical centers and were allocated to either usual care (n = 35) or a home-based walking exercise intervention for eight weeks (n = 36). The exercise intervention involved brisk walking for 30 minutes three times per week in the evening before supper, with a five-minute warm-up and five-minute cool-down. Questionnaires were delivered in interview format.
Patients were undergoing the active treatment phase of care.
The study was a randomized, controlled trial.
Patients in the exercise group reported significant improvements in sleep quality (p < 0.01) at one and two months, and the mental health dimension of QOL; no change was reported in the control group. Physical components of QOL were also improved in the exercise group (p < 0.0001). Among patients who exercised, enhanced sleep quality also corresponded with reduced bodily pain and improvements over time in the mental health dimension of QOL.
A home-based walking exercise program can be easily incorporated into care for cancer patients who are suffering from sleep disturbances and may benefit sleep quality and aspects of QOL.
A home-based exercise program appears promising for improving sleep quality and QOL for cancer patients that can easily be incorporated into care, but further study is warranted with more objective measures and measurement of potential confounding variables.

To examine the effectiveness of an exercise program on quality of life (QOL), fatigue, sleep disturbances, exercise self-efficacy, exercise behavior, and exercise capacity in women with breast cancer.
Patients were randomly assigned to an exercise or usual care group. The exercise intervention was a six-week walking program based on modified exercise guidelines of the American Cancer Society and American College of Sports Medicine. This program included use of a heart rate ring monitor, pedometer, weekly telephone call, weekly meetings, and an exercise diary. Exercise was of low to moderate intensity (40%–60% maximum heart rate). In this program, patients did weekly goal setting and were given advice and information, and several specific strategies were described that were intended to boost self-efficacy. Patients were oriented to the exercise program prior to surgery, and exercise was begun within a few days after surgery. Data were collected 24 hours prior to surgery and at 24 hours prior to the first cycle of chemotherapy, 7 to 10 days after chemotherapy, and at the end of six weeks.
Patients were undergoing the active treatment phase of care.
The study was a randomized, controlled trial.
The pattern of change in QOL over time showed significant consistent improvement among those in the exercise group compared to usual care controls (p < 0.001). Patterns of change in sleep and sleep disturbance also showed significant improvement over time compared to controls (p < 0.006). The pattern of fatigue showed higher fatigue levels in the exercise group at all study time points. Average fatigue scores changed from 40.5 to 45.8 at week 6 in the exercise group and from 40.1 to 40 with usual care. Patients in the exercise group had significantly better exercise self-efficacy (p ≤ 0.001) and higher levels of exercise behavior (p < 0.001) than those receiving usual care. Patients in the exercise group walked farther on the 6MWT than controls after the intervention (p ≤ 0.001).
Findings showed that a self-managed home exercise program, along with intervention strategies aimed at boosting self-efficacy, had a positive effect on QOL and exercise behavior among women newly diagnosed with breast cancer.
The findings did not show a positive impact of a home-based exercise self-efficacy intervention on fatigue in the first six weeks after surgery in newly diagnosed patients. However, over a longer period of time, patients in the exercise group did better. Nurses may need to educate patients that adherence to an exercise program may not show results in the short term and that effects may take some time to be felt. Nurses can educate and encourage patients to exercise at home, and support activities to boost patient sense of efficacy may improve patient adherence to an exercise prescription.

To evaluate the impact of a home-based walking program on patient symptoms of fatigue, sleep disturbances, and mood.
Patients were randomly assigned to the walking program or a usual care control group. The exercise intervention included a walking prescription based on the American College of Sports Medicine guidelines. The targeted exercise prescription included a brisk 20- to 30-minute walk with five-minute warm-ups and cool-downs five days per week. Exercise participants wore pedometers. Usual care patients wore pedometers during the first two weeks only. Throughout the study, patients in both groups received telephone contact on a biweekly basis to discuss physical activity and any concerns. For those in the exercise program, adjustments to the program were made, barriers to walking were discussed, and strategies for resolution were planned.
Patients were undergoing the active antitumor treatment phase of care.
This was a randomized, controlled trial.
Analysis of dropouts showed that significantly more ethnic minorities and those with lower educational levels withdrew (p < 0.03). There were no differences at the end of the study in sleep quality. There were no differences between groups in overall mean emotional distress scores; however, dose-response analysis showed that those who exercised more had less emotional distress (p = 0.03). There were no between-group differences in fatigue; however, analysis showed that those who exercised more had lower fatigue scores (p = 0.03). Subgroup analysis among patients with prostate cancer showed that exercise group members had better sleep quality (p < 0.001), less emotional distress (p = 0.048), and less fatigue (p = 0.009). PAQ findings were moderately correlated with pedometer results, suggesting that the PAQ may be a reasonable measure of exercise dose (Spearman = 0.37; p = 0.002).
Findings suggested that a home-based exercise program can be beneficial in patients receiving cancer treatment to reduce fatigue. Among patients with prostate cancer, the program resulted in improved sleep quality and less emotional distress and fatigue.
A home-based walking program is a simple intervention that can be beneficial to patients, and study findings showed that patients who exercised more had less fatigue and improved mood. In patients other than patients with prostate cancer, it did not appear that exercise improved sleep quality. This study included biweekly telephone follow-ups. Other studies have not shown the same level of results with home-based walking, suggesting that the follow-up component is probably important to maintain patient exercise program use. Of interest, patients who were less educated and of ethnic minorities were more likely to drop out of the study. This suggests that these groups of patients need to be examined more in order to see what interventions will be most likely to appeal to them.

Oncology Nursing Forum, 30, 441–454; discussion 441–454.
Patients met twice a week for 12 weeks for exercise and education. Outcomes were exercise tolerance, activity, sleep, and quality of life (QOL).
Patients were either undergoing the active treatment or long-term follow-up phase of care.
This was a prospective, feasibility study with repeated measures.
No improvement was found in sleep patterns per actigraphy; improved subjective rating was noted.
