Physical activity, long-term symptoms, and physical health-related quality of life among breast cancer survivors: a prospective analysis

Family-Focused Facilitated Fitness: Feasibility and Acceptability of a Couple-Based Physical Activity Intervention for Hematopoietic Cell Transplant Recipients and Their Caregiving Partners

Reductions in physical activity (PA) are common among patients following hematopoietic cell transplantation, and a risk factor for poor physical functioning. PA among spouses/cohabiting partners, who frequently serve as the patient's primary caregiver, may also be reduced due to caregiving demands and limited bandwidth for self-care. In addition, the patient-caregiver relationship can be compromised, and communication patterns disrupted. All PA interventions in the hematopoietic cell transplantation setting have focused entirely on patients, ignoring an opportunity to synergistically engage and benefit the caregiver as well. We sought to test feasibility and acceptability of a couple-based intervention entitled Family-Focused Facilitated Fitness (FFFF), designed to improve PA as assessed by daily step counts among both patients undergoing hematopoietic cell transplantation and their caregivers. Guided by interdependence and communal coping perspectives, FFFF is an 8-week, remotely-delivered intervention that provides training in communication skills and joint problem-solving to help patients and caregivers support one another in PA. Participants are also given a Fitbit to track their steps and weekly individualized step prescription based on the 75th percentile ranked value of their last 7 recorded daily step counts. A priori benchmarks for feasibility and acceptability in this single-arm pilot were as follows: 50% of eligible couples would agree to participate, 70% of couples would attend all 8 sessions, 80% of participants would provide valid Fitbit wear data 4/7 days/ week, and among sessions reviewed for treatment fidelity, 85% of treatment protocol elements would be covered. Couples were recruited prior to transplant. Among 26 couples approached and deemed eligible, 17 enrolled (65% agreement) and completed baseline assessment. Three couples later withdrew after transplantation but prior to receiving the intervention, resulting in 14 couples commencing the intervention, on average 21 days post-transplant. Four couples subsequently discontinued due to medical complications (n = 3) or caregiver schedule (n = 1). Among the 10 couples who completed the intervention, the percentage of participants meeting our benchmark of valid Fitbit wear at least 4 days per week was 85% in week 1, 90% in weeks 2 to 7, and 80% in week 8. Treatment fidelity was 95% on average across 24 sessions reviewed (3 cases). Treatment satisfaction scores were uniformly high across multiple dimensions, with all means above 4 on the 1 to 5 scale. Daily step counts among those attending all 8 intervention sessions increased from 2249 ± 302 steps/day in week 1 to 4975 ± 1377 steps/day in week 8 among patients, and from 8676 ± 3760 steps/day in week 1 to 9838 ± 3723 steps/day in week 8 among caregivers. Qualitative feedback indicated perceived mental and physical health benefits of the program. Participants also offered suggestions for adaptations to accommodate medical setbacks and constraints. All a priori feasibility benchmarks were met or exceeded. Results offer promise for utility of the program to engage and leverage patient-caregiver dyads to increase PA following transplant. An investigation using a randomized controlled design will be necessary to adequately examine change over time relative to control and its possible impact on clinical and patient-reported outcomes.

Physical activity and pain in people with cancer: a systematic review and meta-analysis

PURPOSE

Physical activity can provide analgesic benefit but its effect on cancer-related pain is unclear. This review synthesised and appraised the evidence for the effect of physical activity on pain in people living with or beyond cancer.

METHODS

A systematic search of Ovid Medline and Embase was performed to identify randomised controlled trials (RCTs), randomised cross-over studies (RXTs), and prospective observational studies that examined physical activity and pain outcomes in adults living with or beyond cancer. Meta-analyses were performed to generate effect estimates. Risk of bias was assessed, and the GRADE system was used to assess evidence quality.

RESULTS

One hundred twenty-one studies (n = 13,806), including 102 RCTs, 6 RXTs, and 13 observational studies, met the criteria for inclusion. Meta-analyses of RCTs identified a decrease in pain intensity (n = 3734; standardised mean difference (SMD) - 0.30; 95% confidence interval (CI) - 0.45, - 0.15) and bodily pain (n = 1170; SMD 0.28; 95% CI 0.01, 0.56) but not pain interference (n = 207; SMD - 0.13, 95% CI - 0.42, 0.15) following physical activity interventions. Individual studies also identified a reduction in pain sensitivity but not analgesic use, although meta-analysis was not possible for these outcomes. High heterogeneity between studies, low certainty in some effect estimates, and possible publication bias meant that evidence quality was graded as very low to low.

CONCLUSION

Physical activity may decrease pain in people living with and beyond cancer; however, high heterogeneity limits the ability to generalise this finding to all people with cancer or to specific types of cancer-related pain.

Pain associated with breast cancer: etiologies and therapies

Pain associated with breast cancer is a prevalent problem that negatively affects quality of life. Breast cancer pain is not limited to the disease course itself but is also induced by current therapeutic strategies. This, combined with the increasing number of patients living with breast cancer, make pain management for breast cancer patients an increasingly important area of research. This narrative review presents a summary of pain associated with breast cancer, including pain related to the cancer disease process itself and pain associated with current therapeutic modalities including radiation, chemotherapy, immunotherapy, and surgery. Current pain management techniques, their limitations, and novel analgesic strategies are also discussed.

Patterns of Physical Activity and the Role of Obesity and Comorbidities Among Long-term African American Breast Cancer Survivors

PURPOSE

Physical activity (PA) has many health benefits for cancer survivors, but little research has examined patterns and correlates in African American women, who have a higher burden of comorbidities and obesity. We examined PA types and patterns overall and by obesity and comorbidities among long-term (> 5 years) breast cancer survivors.

METHODS

This cross-sectional study included 323 women who were previous participants of a case-only study in three southeastern states. Women completed a survivorship-focused questionnaire using validated measures to collect data on cancer treatment, PA (recreational, household, transportation) and other lifestyle factors, and comorbidities. Logistic regression models estimated adjusted ORs and 95% CIs for total PA (all three types, categorized as tertiles) and meeting PA guidelines (> 150 min/week of exercise).

RESULTS

The mean age of women was 59.1 years (range 27.9-79.5). The most frequent PA types (≥ 1/month) included routine household cleaning (92.9%), shopping (94.7%), walking slowly (42.1%), and walking briskly (40.6%). Less than 40% met PA guidelines. Women with more total comorbidities, arthritis, and obesity had lower levels of total PA (minutes/week) and/or recreational PA. In adjusted models, BMI ≥ 35 kg/m2 was associated with reduced odds of total PA (OR = 0.33, 95% CI 0.12-0.88, highest tertile). Arthritis was associated with reduced odds of meeting PA guidelines (OR = 0.61, 95% CI 36-1.05).

CONCLUSIONS

Close to 60% of African American breast cancer survivors did not meet PA guidelines based on recreational PA participation. Household PA was an important source of PA. Comorbidities and obesity were associated with both reduced total PA and not meeting PA guidelines.

Effect of the Fit2Thrive Intervention on Patient-reported Outcomes in Breast Cancer Survivors: A Randomized Full Factorial Trial

BACKGROUND

Moderate to vigorous physical activity (MVPA) interventions improve patient-reported outcomes (PROs) of physical and psychological health among breast cancer survivors (BCS); however, the effects of specific intervention components on PROs are unknown.

PURPOSE

To use the Multiphase Optimization Strategy (MOST) to examine overall effects of the Fit2Thrive MVPA promotion intervention on PROs in BCS and explore whether there are intervention component-specific effects on PROs.

METHODS

Physically inactive BCS [n = 269; Mage = 52.5 (SD = 9.9)] received a core intervention (Fitbit + Fit2Thrive smartphone app) and were randomly assigned to one of 32 conditions in a full factorial experiment of five components ("on" vs. "off"): (i) support calls, (ii) deluxe app, (iii) text messages, (iv) online gym, and (v) buddy. Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires assessed anxiety, depression, fatigue, physical functioning, sleep disturbance and sleep-related impairment at baseline, post-intervention (12-week), and 24-week follow-up. Main effects for all components at each time point were examined using an intention to treat mixed-effects model.

RESULTS

All PROMIS measures except sleep disturbance significantly improved (p's < .008 for all) from baseline to 12-weeks. Effects were maintained at 24-weeks. The "on" level of each component did not result in significantly greater improvements on any PROMIS measure compared to the "off" level.

CONCLUSIONS

Participation in Fit2Thrive was associated with improved PROs in BCS, but improvements did not differ for "on" vs. "off" levels for any component tested. The low-resource Fit2Thrive core intervention is a potential strategy to improve PROs among BCS. Future studies should test the core in an RCT and examine various intervention component effects in BCS with clinically elevated PROs.

Factors associated with weight gain in pre- and post-menopausal women receiving adjuvant endocrine therapy for breast cancer

PURPOSE

Weight gain after breast cancer poses health risks. We aimed to identify factors associated with weight gain during adjuvant endocrine therapy (AET).

METHODS

Women initiating AET enrolled in a prospective cohort. Participants completed FACT-ES plus PROMIS pain interference, depression, anxiety, fatigue, sleep disturbance and physical function measures at baseline, 3, 6, 12, 24, 36, 48 and 60 months. Treatment-emergent symptoms were defined as changes in scores in the direction indicative of worsening symptoms that exceeded the minimal important difference at 3 and/or 6 months compared to baseline. We used logistic regression to evaluate associations of clinicodemographic features and treatment-emergent symptoms with clinically significant weight gain over 60 months (defined as ≥ 5% compared to baseline) in pre- and post-menopausal participants.

RESULTS

Of 309 participants, 99 (32%) were pre-menopausal. The 60 months cumulative incidence of clinically significant weight gain was greater in pre- than post-menopausal participants (67% vs 43%, p < 0.001). Among pre-menopausal participants, treatment-emergent pain interference (OR 2.49), aromatase inhibitor receipt (OR 2.8), mastectomy, (OR 2.06) and White race (OR 7.13) were associated with weight gain. Among post-menopausal participants, treatment-emergent endocrine symptoms (OR 2.86), higher stage (OR 2.25) and White race (OR 2.29) were associated with weight gain while treatment-emergent physical function decline (OR 0.30) was associated with lower likelihood of weight gain.

CONCLUSIONS

Weight gain during AET is common, especially for pre-menopausal women. Clinicodemographic features and early treatment-emergent symptoms may identify at risk individuals.

IMPLICATIONS FOR CANCER SURVIVORS

Patients at risk for weight gain can be identified early during AET.

Does participation in therapeutic exercise programs after finishing oncology treatment still ensure an adequate health status for long-term breast cancer survivors? A ≥ 5 years follow-up study

PURPOSE

The aims of this study were to evaluate whether the effects of two therapeutic exercise programs are sustained over time (≥ 5 years) in long-term breast cancer survivors (LTBCS). Second, to determine the influence of the current level of physical activity (PA) performed on cancer-related fatigue (CRF) that these patients may present ≥5 years later.

METHODS

A prospective observational study was conducted with a cohort of 80 LTBCS in Granada during 2018. Firstly, considering their participation in one of the programs, they were allocated into two groups: usual care and therapeutic exercise program, to assess CRF, pain and pressure pain sensitivity, muscle strength, functional capacity, and quality of life. Secondly, they were also classified into 3 groups according to current level of weekly PA performed: ≤ 3, 3.1-7.4, and ≥ 7.5 (MET-hour/week) respectively, to assess its impact over CRF.

RESULTS

Although the positive effects of the programs are not sustained over time, a trend toward significance can be observed for a greater reduction in overall CRF levels, lower intensity of pain in the affected arm and cervical region, and greater functional capacity and quality of life in the group that underwent therapeutic exercise. Additionally, 66.25% of LTBCS are inactive ≥ 5 years after completion of the program and furthermore, such inactivity is accompanied by higher CRF levels (P .013 to .046).

CONCLUSION

The positive effects of therapeutic exercise programs are not maintained over time for LTBCS. Additionally, more than half of these women (66.25%) are inactive ≥ 5 years after completion of the program, this inactivity being accompanied by higher levels of CRF.

Development and preliminary testing of the cancer-related fatigue comprehensive assessment scale in cancer survivors

BACKGROUND

Tailored management of cancer-related fatigue (CRF) is important for effective coping; however, it has been hindered by the lack of a comprehensive tool that assesses both symptoms and treatable influencing factors.

AIMS AND OBJECTIVES

The aim was to develop a cancer-related fatigue comprehensive assessment scale (CRF-CAS) and assess its psychometric properties.

DESIGN

This was a mixed-method study.

METHODS

The study included two phases which were conducted in Zhejiang Province, China. In phase one, a literature search, brainstorming sessions, Delphi studies, cognitive interviews and a pilot study were conducted to construct and revise CRF-CAS indicators. In phase two, a questionnaire-based survey was conducted among cancer survivors. Item analysis was used to select and optimize indicators. Cronbach's α was calculated for reliability analysis. Validity analysis included concurrent validity and structural validity.

RESULTS

A 93-item tool was initially constructed. Phase one ended with revision and optimization. The preliminary scale included five dimensions (CRF symptoms, physical activity, cognitive-emotional status, sleep status, nutritional status) and 30 items. The mean item-content validity index (I-CVI) and scale-level CVI universal agreement (S-CVI/UA) were .98, and the adjusted mean values of Kappa for indicators ranged from .91-1, as evaluated by the expert group. The Pearson correlation coefficient between the CRF-CAS and criterion scales ranged from .337-.862. Cronbach's α coefficient ranged from .624-.728. Respondents agreed that the scale was acceptable for administration and that it contributed to decision-making in fatigue management. Confirmatory factor analysis (CFA) indicated that the CRF-CAS fit well.

CONCLUSIONS

The construction process of the CRF-CAS, involving panel discussion and expert and participant evaluations, was shown to be scientific and feasible. The CRF-CAS had relatively good validity and reliability in version 5 of its preliminary scale, which requires further improvement in future studies.

Conclusions

American Cancer Society nutrition and physical activity guideline for cancer survivors

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

A Comprehensive Evaluation of Health-Related Life Quality Assessment Through Head and Neck, Prostate, Breast, Lung, and Skin Cancer in Adults

Health assessment data assists the well-being and patient care teams' process in drawing up a care and assistance plan and comprehending the requirements of the patient. Comprehensive and precise data about the Quality of Life of cancer patients play a significant part in the development and organization of cancer patient care. Quality of Life has been used to mean a variety of various things, such as health situation, physical function, symptoms, psychosocial modification, well-being, enjoyment of life, and happiness. Chronic diseases such as cancer are among the disorders that severely affect people's health and consequently their Quality of Life. Cancer patients experience a range of symptoms, including pain and various physical and mental conditions that negatively affect their Quality of Life. In this article, we examined cancer and the impact that this disease can have on the Quality of Life of cancer patients. The cancers examined in this article include head and neck, prostate, breast, lung, and skin cancers. We also discussed health assessment and the importance and purpose of studying patients' Quality of Life, especially cancer patients. The various signs and symptoms of the disease that affect the Quality of Life of patients were also reviewed.

Factors Impacting Functioning Level of Cancer Survivors in Turkey

The purpose of this study was to investigate the relationships between demographic variables, personal factors, impairment-related variables, and functioning levels of cancer survivors in Turkey. Data for this study were collected from a major oncology institute and a nonprofit cancer organization in Turkey. Hierarchical regression analyses were conducted to investigate the sequential effect of demographic variables (i.e., age, gender, income, and education), personal factors (i.e., core self-evaluations, purpose in life, and religiosity), and impairment-related variables (i.e., pain, fatigue, perceived stress, and sleep disturbance) on the functioning level of Turkish cancer survivors (i.e., physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning). The results indicated that impairment-related variables explained a significant amount of variance in functioning scores above and beyond demographic and personal factors. Pain intensity and perceived stress were most prominent factors impacting functioning levels of Turkish cancer survivors. Pain and stress self-management training, psychotherapy and counseling, physical activity and exercise, and cognitive remediation training are recommended interventions to increase the functioning level and well-being of cancer survivors.

Couple Communication in Cancer: Protocol for a Multi-Method Examination

Cancer and its treatment pose challenges that affect not only patients but also their significant others, including intimate partners. Accumulating evidence suggests that couples' ability to communicate effectively plays a major role in the psychological adjustment of both individuals and the quality of their relationship. Two key conceptual models have been proposed to account for how couple communication impacts psychological and relationship adjustment: the social-cognitive processing (SCP) model and the relationship intimacy (RI) model. These models posit different mechanisms and outcomes, and thus have different implications for intervention. The purpose of this project is to test and compare the utility of these models using comprehensive and methodologically rigorous methods. Aims are: (1) to examine the overall fit of the SCP and RI models in explaining patient and partner psychological and relationship adjustment as they occur on a day-to-day basis and over the course of 1 year; (2) to examine the fit of the models for different subgroups (males vs. females, and patients vs. partners); and (3) to examine the utility of various methods of assessing communication by examining the degree to which baseline indices from different measurement strategies predict self-reported adjustment at 1-year follow up. The study employs a longitudinal, multi-method approach to examining communication processes including: standard self-report questionnaires assessing process and outcome variables collected quarterly over the course of 1 year; smartphone-based ecological momentary assessments to sample participant reports in real time; and laboratory-based couple conversations from which we derive observational measures of communicative behavior and affective expression, as well as vocal indices of emotional arousal. Participants are patients with stage II-IV breast, colon, rectal, or lung cancer and their spouses/partners, recruited from two NCI-designated comprehensive cancer centers. Results will be published in scientific journals, presented at scientific conferences, and conveyed to a larger audience through infographics and social media outlets. Findings will inform theory, measurement, and the design and implementation of efficacious interventions aimed at optimizing both patient and partner well-being.

Physical activity and sedentary time: associations with fatigue, pain, and depressive symptoms over 4 years post-treatment among breast cancer survivors

INTRODUCTION

Despite the recommendations for cancer survivors to engage in physical activity (PA), little is known about the effects of both PA and sedentary time (ST) on key health symptoms. This study prospectively examined the lifestyle behaviors of moderate-to-vigorous PA (MVPA) and ST as predictors of depressive symptoms, pain, and fatigue in breast cancer survivors using longitudinal data from early post-treatment to 4-year survivorship.

METHODS

Breast cancer survivors (n = 199, mean(SD) age = 55.0(11.0) years) self-reported depressive symptoms, pain, and fatigue, and wore an accelerometer to measure MVPA and ST every 3 months during the first year (times 1 to 5) and 2 and 4 years (times 6 and 8) post-cancer treatment. Linear mixed models were adjusted for personal (e.g., age, BMI, education) and cancer (e.g., stage, time since treatment) variables.

RESULTS

MVPA and ST were independent predictors of depressive symptoms, but not fatigue, and only ST was associated with pain over 4 years post-treatment. Higher levels of MVPA were associated with lower scores of depressive symptoms ([Formula: see text] (95%CI): - 0.062 (- 0.092, - 0.031) p < .001), whereas higher levels of ST were associated with higher scores of depressive symptoms ([Formula: see text] (95%CI): 0.023 (0.017, 0.028) p < .001). Higher levels of ST were associated with increased pain level over time ([Formula: see text] (95%CI): 0.017 (0.007, 0.027) p = .001).

CONCLUSIONS

Rehabilitation interventions should aim to both increase MVPA and reduce ST to promote health and well-being among breast cancer survivors, in particular during the early post-treatment period.

Association Between Different Domains of Physical Activity and Body Adiposity Indicators in Breast Cancer Survivors

BACKGROUND

To analyze the relationship between different physical activity (PA) domains and adiposity indicators in breast cancer survivors.

METHODS

This is a cross-sectional study, composed of 115 breast cancer (BC) survivors. Measurements of weight, height, waist circumference (WC), and hip circumference were objectively collected, as well as the analysis of body fat percentage through bioelectrical impedance analysis. The PA level was assessed by the Baecke questionnaire including domains related to occupational activity, leisure-time activity, and transportation, while the time spent in sedentary behavior was assessed through self-reported screen-time. Socioeconomic status was assessed through the Brazilian criteria for economic classification and considered as a covariate.

RESULTS

BC survivors with higher PA levels in leisure-time activity/sport presented reductions in body fat percentage (β = 1.13%; CI = -2.06; -0.21), BMI (β = 0.80 kg/m²; CI = -1.50; -0.11), WC (β = 1.89 cm; CI = -3.54; -0.23), and waist-to-height ratio (β = 0.13 cm; CI = -0.23; -0.02). Similar values were observed in PA during transportation and in total. There was no correlation between PA at work and adiposity indicators.

CONCLUSION

Different PA domains were inversely related to body adiposity in BC survivors.

Exercise participation, barriers, and preferences in Korean prostate cancer survivors

Objective: To identify patterns of physical activity (PA) participation, exercise preference, and barriers of stage 2-3 prostate cancer survivors across cancer trajectories based on selected demographic and medical variables.Design: The current study is a descriptive cross-sectional study which included data from a total of 111 prostate cancer survivors, at Shinchon Severance Hospital, Seoul, Korea. The survey includes PA levels before and after prostate cancer diagnosis, exercise barriers, and preferences.Results: Moderate- to vigorous-intensity PA levels were significantly lower after cancer diagnosis (vigorous PA:41.9 ± 123.1 min/week vs. 4.6 ± 29.8 min/week, p < 0.001; moderate PA: 159.9 ± 240.0 min/week vs. 56.8 ± 129.7 min/week, p < .001) compared to their PA level before cancer diagnosis. Perceived exercise barriers were distinctly different according to participants' age and time since surgery. The two most prevalent exercise barriers among prostate cancer survivors <65 years were lack of time (28.6%) and poor health (26.5%), whereas the exercise barriers for prostate cancer survivors aged ≥65 years were lack of exercise facilities (21.4%) and lack of exercise information (17.9%). Furthermore, within 6 months after surgery, prostate cancer survivors perceived poor health (29.5%) and pain at the surgery site (29.5%) to be the two most prevalent exercise barriers. 6 months after surgery, prostate cancer survivors perceived lack of time (21.3%) and poor health (14.8%) to be the two most prevalent exercise barriers. Walking, pelvic floor and Kegel exercises were three most preferred exercises among prostate cancer survivors in our study, which uniquely differ according to time since surgery.Conclusion: This study showed significant reduction in PA levels among prostate cancer survivors and their perceived exercise barriers were distinct according to their age and time since surgery. Therefore, PA and exercise recommendation should be specific to their personal characteristics such as age and time since surgery.

Ethnic and biological differences in the association between physical activity and survival after breast cancer

Physical activity is recommended for most cancer patients as a nonpharmacological therapy to improve prognosis. Few studies have investigated the association between physical activity and breast cancer prognosis by ethnicity, biological, and modifiable risk factors for mortality. We investigated the association between physical activity and long-term survival among breast cancer survivors. A total of 397 survivors (96 Hispanic and 301 non-Hispanic White (NHW)) from the New Mexico HEAL study contributed baseline and biological data approximately 6 months after diagnosis. Study outcomes included all-cause, breast cancer-specific, and non-breast cancer mortality. The exposure was self-reported physical activity within the past month. Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox Proportional Hazards regression. A total of 133 deaths (53 breast cancer-specific deaths) were observed after a median follow-up time of 13 years. Engaging in >6.9 metabolic equivalent hours/week (MET-h/week) of moderate to vigorous physical activity (active) was inversely associated with all-cause mortality among all women (HR 0.66, 95% CI 0.43-0.99) and NHWs (HR 0.58, 95% CI 0.36-0.94). Active NHW women also had a reduced risk of non-breast cancer mortality (HR 0.56, 95% CI 0.31-0.99), compared to inactive women (0 MET-h/week). In subgroups, we observed the inverse associations with all-cause mortality among women >58 years old (p-interaction= 0.03) and with localized stage (p-interaction = 0.046). Our results confirm the protective association between physical activity and mortality after breast cancer diagnosis, and demonstrate that this association significantly differs by age and cancer stage. Larger studies are warranted to substantiate our findings.

Cancer-related Fatigue in Breast Cancer Survivors: A Review

Fatigue has been the most distressing and frequent symptom in breast cancer (BC) survivors after treatment. Although fatigue can occur in other cancer survivors, women with a history of BC might share some distinctive features. The present study aimed to recapitulate the knowledge about risk factors and correlates of cancer-related fatigue (CRF) in BC survivors after oncologic therapy. An electronic data search was conducted in PubMed using the terms "fatigue," "breast," "cancer," and "survivors." Records were included if they were original articles, available in English, had used a quantitative scale, had > 100 participants, and had excluded women with BC relapse. BC survivors were required to have finished their treatments ≥ 2 months before, except for hormonal therapy. The physiopathology and other interventions were considered beyond the scope of our review. The correlates were subsequently classified into 7 main categories: (1) sociodemographic data, (2) physical variables, (3) tumor- and treatment-related variables, (4) comorbidities, (5) other symptoms, (6) psychological issues, and (7) lifestyle factors. Fatigue was consistently greater in younger, obese, and diabetic women. Women reporting fatigue often communicated symptoms such as pain, depression, insomnia, and cognitive dysfunction. Coping strategies such as catastrophizing could play an important role in the persistence of fatigue. However, tumor characteristics, previous treatments received, and physical activity were not consistently reported. CRF was a strong predictor of the quality of life of BC survivors after treatment. In conclusion, we found CRF was a frequent and serious symptom that severely affects the quality of life of BC survivors after treatment. Health practitioners require more awareness and information about CRF.

Relationship of objectively measured physical activity and sedentary behaviour with health-related quality of life among breast cancer survivors

Background

Lack of physical activity throughout one’s lifetime has been associated with obesity and it is also an important risk factor of breast cancer. This study aimed to determine the relationship between objectively measured physical activity and sedentary behaviour with health-related quality of life (HRQoL) among breast cancer survivors in the East Coast region of Peninsular Malaysia.

Methods

A cross-sectional study involving 83 breast cancer survivors was carried out in two main government referral hospitals in the region. Participants wore the ActivPAL3™ microdevice physical activity monitor for seven consecutive days. The validated European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (EORTC QLQ–C30) and Breast Cancer Supplementary Measure (EORTC QLQ-BR23) were used to measure their HRQoL. Multiple linear regression analysis was conducted to determine the relationship between objectively measured physical activity and sedentary behaviour with HRQoL.

Results

Longer time spent on moderate to vigorous physical activity (MVPA) was significantly associated with an improvement of HRQoL (p = 0.039) whereas longer time spent on sedentary behaviour significantly reduced the functioning score (p = 0.005). In addition, prolonged sedentary bouts were also significantly associated with better body image that led to improved HRQoL (p = 0.013).

Conclusions

The study findings suggest that an increase in the time spent on MVPA was associated with improved HRQoL while sedentary behaviour was associated with poorer HRQoL among breast cancer survivors. Thus, it is essential to displace sedentary behaviour with MVPA to improve the quality of life of breast cancer survivors.

Intensity- and domain-specific physical activity levels between cancer survivors and non-cancer diagnosis individuals: a propensity score matching analysis

PURPOSE

To examine intensity- and domain-specific physical activity (PA) levels between Korean cancer survivors compared with non-cancer individuals.

METHODS

We used data from the 2014-2016 Korean National Health and Nutrition Examination Survey (KNHNES) to compare PA levels between 639 cancer survivors and 15,352 non-cancer individuals. Using the 1:5 propensity score matching analysis by sex, age, body mass index (BMI), and education level, 3195 non-cancer individuals were selected. Global Physical Activity Questionnaire (GPAQ) was used to assess PA levels.

RESULTS

Cancer survivors were more likely to participate in a leisure-time PA (64.5 ± 157.9 vs. 51.8 ± 145.3 min/week, p < 0.002) compared with non-cancer individuals, while no difference was observed between groups in work and transportation. Cancer survivors undergoing treatment participated in more leisure-time PA (80.9 ± 169.2 vs. 56.6 ± 151.8 min/week, p < 0.02) compared with cancer survivors who completed cancer treatment. However, we found no significant difference in vigorous-intensity PA (18.8 ± 113.9 vs. 20.5 ± 156.1 min/week, p = 0.56) and moderate-intensity PA (186.2 ± 313.1 vs. 203.1 ± 355.3 min/week, p = 0.17) levels between cancer survivors and non-cancer individuals.

CONCLUSIONS

This study showed that cancer survivors were more participated in leisure-time PA compared with age, gender, BMI, and education levels matched non-cancer individuals.

Quality of life in "chronic" cancer survivors: a meta-analysis

PURPOSE

Cancer survivors are now living longer giving rise to a new concept-chronic cancer as survivors continue to face long-term consequences of cancer and its treatment. For these survivors, QOL becomes a vital consideration in understanding their survivorship and the long-term impact of cancer and its treatment. The primary aim of this review is to describe QOL in cancer survivors two or more years from diagnosis.

METHODS

A meta-analysis was completed of relevant studies assessing QOL in long-term cancer survivorship using PubMed, CINHAL, and PsycINFO. A total of 64 articles met inclusion criteria and included in the analysis. Standardized effect sizes and errors were calculated using previously published standard QOL pass rates to compare QOL across measurement tools and calculate cumulative effect sizes (CES). Fixed-effect or random-effects models were used based on the presence of significant heterogeneity of ≤ 0.10.

RESULTS

Physical health (CES = - 0.894; CI, - 1.472, - 0.316), role-physical health (CES = - 2.039; CI, - 2.643, - 1.435), and mental health (CES = - 0.870; CI, - 1.447, - 0.292) had large, negative cumulative effect sizes signifying worse QOL compared with acceptable QOL rates. Tested moderators, cancer type, average age, country of origin, time since diagnosis, or decade of diagnosis, were not significant to explain heterogeneity between included studies.

CONCLUSION

QOL is significantly impacted 2 to 26 years after cancer diagnosis. More research is needed to determine possible moderators of QOL in long-term cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

QOL continues to be significantly impacted in long-term cancer survivorship. More research is needed to understand the impact of these findings on care needs for survivors with chronic cancer.

The Physiology of Optimizing Health with a Focus on Exercise as Medicine

Physical inactivity is one of the leading health problems in the world. Strong epidemiological and clinical evidence demonstrates that exercise decreases the risk of more than 35 different disorders and that exercise should be prescribed as medicine for many chronic diseases. The physiology and molecular biology of exercise suggests that exercise activates multiple signaling pathways of major health importance. An anti-inflammatory environment is produced with each bout of exercise, and long-term anti-inflammatory effects are mediated via an effect on abdominal adiposity. There is, however, a need to close the gap between knowledge and practice and assure that basic research is translated, implemented, and anchored in society, leading to change of praxis and political statements. In order to make more people move, we need a true translational perspective on exercise as medicine, from molecular and physiological events to infrastructure and architecture, with direct implications for clinical practice and public health.

The role of neuro-immune interactions in cancer-related fatigue: Biobehavioral risk factors and mechanisms

Fatigue is a common and distressing symptom in both patients with cancer and cancer survivors. There is substantial variation in the severity and persistence of cancer-related fatigue that may be driven by individual differences in host factors, including characteristics that predate the cancer experience as well as responses to cancer and its treatment. This review examines biobehavioral risk factors linked to fatigue and the mechanisms through which they influence fatigue across the cancer continuum, with a focus on neuro-immune processes. Among psychosocial risk factors, childhood adversity is a strong and consistent predictor of cancer-related fatigue; other risk factors include history of depression, catastrophizing, lack of physical activity, and sleep disturbance, with compelling preliminary evidence for loneliness and trait anxiety. Among biologic systems, initial work suggests that alterations in immune, neuroendocrine, and neural processes are associated with fatigue. The identification of key risk factors and underlying mechanisms is critical for the development and deployment of targeted interventions to reduce the burden of fatigue in the growing population of cancer survivors. Given the multidimensional nature of fatigue, interventions that influence multiple systems may be most effective.

Putting the life in lifestyle: Lifestyle choices after a diagnosis of cancer predicts overall survival

BACKGROUND

The aim of this study was to examine predictors of health behaviors over time and the link between health behaviors and survival after a diagnosis of advanced cancer.

METHODS

Patients with a diagnosis of advanced cancer were administered a battery of questionnaires measuring optimism, depressive symptoms, physical activity, intake of fruits and vegetables, and alcohol and tobacco use over an 18-month period. Analyses included generalized linear mixed models and Cox regression survival analyses.

RESULTS

Of the 334 patients enrolled in the study, the mean age at cancer diagnosis was 62 years; the majority were male (62.3%) and white (91%). Twenty percent of the patients reported using alcohol, 19% reported using tobacco, 19% reported eating fewer fruits and vegetables than recommended by the Centers for Disease Control and Prevention and 28% reported physical inactivity after the diagnosis of advanced cancer. Clinical levels of depressive symptoms were associated with lower intake of fruits and vegetables (t = 2.67, P = .007) and physical inactivity (t = 2.11, P = .035). Dispositional optimism was positively associated with physical activity (t = -2.16, P = .031) and a lower frequency of tobacco use (Z = -2.42, P = .015). Multivariate analyses revealed that after adjusting for demographic variables (age and sex), depressive symptoms, and disease-specific factors (diagnosis, tumor size, cirrhosis, vascular invasion, and number of lesions), alcohol use (χ²  = 4.1186, P = .042) and physical inactivity (χ²  = 5.6050, P = .018) were linked to an poorer survival.

CONCLUSIONS

Greater dissemination and implementation of effective interventions to reduce alcohol use and increase physical activity in cancer patients are recommended.

Exercise and Education Program After Breast Cancer: Benefits on Quality of Life and Symptoms at 3, 6, 12, and 24 Months' Follow-up

BACKGROUND

Various clinical trials have demonstrated the benefits of physical training offered during and/or after breast cancer treatments. However, given the variety of adverse events that may be encountered, physical training could be combined with psychologic, relational, and social guidance. This kind of multidisciplinary program, as well as its long-term effects, have been little studied so far. Therefore, the objective of our study was to determine the benefits at 3, 6, 12, and 24 months of a 3-month exercise and education program among women after breast cancer treatment.

PATIENTS AND METHODS

Two hundred nine outpatients treated for primary breast carcinoma were divided into a control group (n = 106) and an experimental group (n = 103) which underwent a 3-month rehabilitation program including physical training and psychoeducational sessions. The assessments, performed before the program and at 3, 6, 12, and 24 months after inclusion, included validated questionnaires on quality of life and symptoms.

RESULTS

The analyses revealed an improvement in quality of life and symptoms after the exercise and education program within the experimental group and a maintenance of these improvements during the 2 years of follow-up. These improvements were significantly better than those in the control group, clearly demonstrating that the program has benefits.

CONCLUSION

This trial identified the benefits of a well-detailed 3-month exercise and education program over 24 months' follow-up among women after breast cancer treatment.

Relationship between time elapsed since completion of radiotherapy and quality of life of patients with breast cancer

BACKGROUND

To investigate the relationship between time elapsed since completion of radiotherapy (RT) and quality of life (QOL) of patients with breast cancer.

METHODS

A total of 300 patients with breast cancer were treated at the First Affiliated Hospital of Anhui Medical University between January 2013 and April 2016. Of these, 212 patients were included in the study. Patients were divided into 4 groups based on the time elapsed since completion of RT. The generic cancer questionnaire, EORTC QLQ-30, and the breast cancer-specific questionnaire, QLQ-BR23, were used to assess the QOL.

RESULTS

Analysis of time elapsed since completion of RT and QOL revealed changes in the scores for role function with passage of time; the third year's scores were the highest. Pain symptoms during the 3rd and 4th years after RT were lower than those during the 1st and 2nd years after RT; scores for financial difficulties fluctuated with passage of time; perception of own body scores improved within first 3 years; sexual activity and enjoyment of sexual activity showed a significant decrease during the 2nd to 4th year post RT. Scores pertaining to concerns about future state of health showed a significant increase during the 2nd to 4th year after RT, while breast symptoms score showed fluctuations with passage of time.

CONCLUSIONS

Social function, pain symptoms, and concerns about future state of health tended to improve with passage of time after RT. Other scales showed no correlation with time elapsed since completion of RT.

Can the Weight of an External Breast Prosthesis Influence Trunk Biomechanics during Functional Movement in Postmastectomy Women?

Introduction

Recent papers indicate that one-side mastectomy can produce deleterious effects on the posture and musculoskeletal system. This study was conducted to better understand the underlying mechanisms involved in trunk motion in external prosthesis users.

Objective

The aim was to evaluate the changes in surface electromyographic (SEMG) activity of the erector spinae muscles (ES) in postmastectomy women with and without breast prostheses during functional body movement tests.

Methods

In 51 one-side postmastectomy women the SEMG muscle activity of bilateral ES was measured during symmetrical and asymmetrical dynamic activities in a counterbalanced manner with different weights of the breast prosthesis. Range-of-motion measurements were taken for forward bending, backward bending, lateral bending, and rotation.

Results

The mean level of the ES activity in the lumbar region was not affected by the weight of the external breast prosthesis during most of the functional body tests (P > 0.05). The activity of ES during functional body tests with and without different external breast prostheses did not differ between the two sides of the trunk (mastectomy and nonmastectomy) for most of the movement tests (P > 0.05).

Conclusion

The lumbar ES activity during functional tests is not associated with the weight of the external breast prosthesis in postmastectomy women.

J, Giraldo PC, Gonçalves AK. Quality of life in breast cancer survivors

Summary Objective: To evaluate the influence of functional capacity (FC) and how it affects quality of life (QoL) in breast cancer survivors. Method: A total of 400 breast cancer survivors were studied - 118 without metastasis, 160 with locoregional metastasis and 122 with distant metastasis. The European Organization for Research and Treatment for Cancer Quality of Life Questionnaire--Core 30 (EORTC QLQ-C30), Breast Cancer-Specific (EORTC QLQ-BR23), and the Karnofsky Performance Scale (KPS) were used to evaluate FC and QoL. Results: Women with distant metastases presented lower KPS 75.3 (SD=12.5) (p<0.001). For QLQ-C30, the mean of the Functional Scale for patients with distant metastasis was 57 (SD=19) (p<0.001), and the mean of the Symptom Scale for patients with distant metastasis was 37 (SD=20) (p<0.001). Both the scales for pain and fatigue showed the highest mean in the groups. For the Global Health Scale, patients without metastasis scored a mean of 62 (SD=24) points, while those with locoregional metastases scored a mean of 63 (SD=21.4), and distant metastasis scored 51.3 (SD=24) points. In the group with distant metastases, 105 (87%) had pain, and the average KPS was 74 (SD=12.0) (p=0.001). Conclusion: Breast cancer was associated with decreased FC, compromised QoL in women with locoregional and distant metastases compared to those without metastasis.

The association between physical activity and health-related quality of life among breast cancer survivors

BACKGROUND

The quality of life for breast cancer survivors has become increasingly important because of their high survival rate and prolonged life expectancy. The purpose of this study was to examine the association of physical activity following diagnosis and health-related quality of life (HRQOL) in breast cancer survivors.

METHODS

We conducted a cross-sectional study of breast cancer survivors. A total of 231 women aged 21-78 years who had been diagnosed with stages I to III breast cancer and had breast cancer surgery at least 6 months prior were recruited from three hospitals between September 2012 and April 2015 and were included in this study. We asked participants about their HRQOL and engagement in physical activity using structured questionnaires. We examined the association between HRQOL levels and physical activity using a generalized linear model.

RESULTS

Breast cancer survivors in the high physical activity group (3rd tertile) were more likely to have lower scores for fatigue (p for trend = 0.001) and pain (p for trend = 0.02) and higher scores for sexual function (p for trend = 0.007) than those in the low physical activity group (1st tertile). When we stratified participants by stage, we found increasing scores for physical functioning (p for trend =0.01) and decreasing scores for fatigue (p for trend = 0.02) with increasing levels of physical activity in breast cancer survivors with stage I breast cancer. In survivors with stages II and III, we found statistically significant associations with fatigue (p for trend = 0.02) and sexual functioning (p for trend = 0.001).

CONCLUSIONS

In conclusion, engagement in physical activity was related to better health-related quality of life among breast cancer survivors. Our findings may warrant further prospective and intervention studies to support the benefit of physical activity in improving the quality of life and survival of Korean breast cancer survivors.

Exploring the Linkage between Activity-Friendly Zoning, Inactivity, and Cancer Incidence in the United States

Background: Physical activity (PA) protects against cancer and enhances cancer survivorship. Given high inactivity rates nationwide, population-level physical activity facilitators are needed. Several authoritative bodies have recognized that zoning and planning helps create activity-friendly environments. This study examined the association between activity-friendly zoning, inactivity, and cancer in 478 of the most populous U.S. counties.Methods: County geocodes linked county-level data: cancer incidence and smoking (State Cancer Profiles), inactivity (Behavioral Risk Factor Surveillance System), 11 zoning measures (compiled by the study team), and covariates (from the American Community Survey and NAVTEQ). For each zoning measure, single mediation regression models and Sobel tests examined whether activity-friendly zoning was associated with reduced cancer incidence, and whether inactivity mediated those associations. All models were clustered on state with robust SEs and significance at the P < 0.05 level.Results: Zoning for crosswalks, bike-pedestrian connectivity, and bike-pedestrian trails/paths were associated with reduced cancer incidence (β between -0.71 and -1.27, P < 0.05), about 1 case per 100,000 for each 10 percentage-point increase in county population exposure to zoning. Except for crosswalks, each association was mediated by inactivity. However, county smoking attenuated these results, with only crosswalks remaining significant. Results were similar for males (with zoning for bike-pedestrian connectivity, street connectivity, and bike-pedestrian trails/paths), but not females, alone.Conclusions: Zoning can help to create activity-friendly environments that support decreased inactivity, and possibly reduced cancer incidence.Impact: Given low physical activity levels nationwide, cross-sectoral collaborations with urban planning can inform cancer prevention and public health efforts to decrease inactivity and cancer.

Exercise as medicine - evidence for prescribing exercise as therapy in 26 different chronic diseases

This review provides the reader with the up-to-date evidence-based basis for prescribing exercise as medicine in the treatment of 26 different diseases: psychiatric diseases (depression, anxiety, stress, schizophrenia); neurological diseases (dementia, Parkinson's disease, multiple sclerosis); metabolic diseases (obesity, hyperlipidemia, metabolic syndrome, polycystic ovarian syndrome, type 2 diabetes, type 1 diabetes); cardiovascular diseases (hypertension, coronary heart disease, heart failure, cerebral apoplexy, and claudication intermittent); pulmonary diseases (chronic obstructive pulmonary disease, asthma, cystic fibrosis); musculo-skeletal disorders (osteoarthritis, osteoporosis, back pain, rheumatoid arthritis); and cancer. The effect of exercise therapy on disease pathogenesis and symptoms are given and the possible mechanisms of action are discussed. We have interpreted the scientific literature and for each disease, we provide the reader with our best advice regarding the optimal type and dose for prescription of exercise.

Physical Activity in Puerto Rican Breast Cancer Survivors

OBJECTIVE

Breast cancer survivors do not engage in appropriate levels of physical activity, despite the known benefits of such activity. This study aims to describe physical-activity levels and the barriers to it in a group of Puerto Rican breast cancer survivors, as well as detailing their preferences for an intervention.

METHODS

Participants who finished their chemotherapy and/or radiotherapy for breast cancer at least 4 months prior to the study were included. Demographic, anthropometric, and clinical data were obtained. The Godin Leisure-Time Exercise Questionnaire (GLTEQ) and questionnaires on exercise self-efficacy, barriers to self-efficacy, modeling, and social support were filled out by study participants. Data on access to exercise equipment and preferences regarding a physical-activity intervention were collected. Descriptive statistics and correlation analyses were performed.

RESULTS

Fifty breast cancer survivors were recruited. Almost all the participants reported that they did not engage in any kind of strenuous physical activity (94%), with more than three fourths (76%) reporting that they did not even participate in any kind of moderate physical activity. The GLTEQ score was associated with barriers to selfefficacy, while the association with exercise self-efficacy approached significance (p = 0.055). Nearly half of the patients (44%) had access to exercise equipment. Preferred methods for the delivery of physical-activity interventions were participating in group settings (72%) and receiving material in the postal mail (44%).

CONCLUSION

The study described herein reports on the low levels of physical activity being practiced by a group of Puerto Rican breast cancer survivors, despite the fact that many of them had access to exercise equipment and facilities. Further studies aimed at understanding breast cancer survivors' barriers to physical activity and at developing culturally competent interventions to increase the levels of such activity are warranted.

Factors Associated with Fatigue in Korean Gastric Cancer Survivors

Background

Gastric cancer is the second most common cancer in Korea. Fatigue is a common symptom among cancer survivors. The aim of this study was to identify factors associated with fatigue in gastric cancer survivors.

Methods

Data were analyzed from 199 gastric cancer survivors who visited a cancer survivor outpatient clinic from July 2013 to June 2014. Patients were surveyed using a questionnaire containing a fatigue severity scale (FSS) and questions regarding associated symptoms. Participants were divided into fatigue (FSS) and non-fatigue groups based on FSS scores (≥4 and <4, respectively). Age, sex, weight, body mass index, cancer stage, pathology, surgery type, chemotherapy, radiotherapy, comorbid disease, family history of cancer, smoking, alcohol consumption, exercise, and laboratory results were investigated.

Results

The fatigue and non-fatigue groups contained 42 and 157 survivors, respectively. Their mean age was 58 years, and the mean post-operative period was 6.58 years. Arthralgia (odds ratio [OR], 12.95; 95% confidence interval [CI], 3.21-52.34), dyspnea (OR, 10.54; 95% CI, 2.94-37.80), dyspepsia (OR, 8.26; 95% CI, 2.63-25.96), changed bowel habits (OR, 4.56; 95% CI, 1.09-19.11), anemia (OR, 3.18; 95% CI, 1.26-8.05), and regular exercise (OR, 0.31; 95% CI, 0.12-0.77) were significantly associated with fatigue in gastric cancer survivors, while weight, treatment, and depressive mood were not.

Conclusion

Arthralgia, dyspnea, dyspepsia, bowel habit change, anemia, and regular exercise are associated with fatigue in gastric cancer survivors.

Circadian rhythm mediates the relationship between physical activity and quality of life in younger and older cancer survivors

Increasing evidence suggests that physical activity (PA) improves the quality of life (QoL) of cancer survivors. However, the biological mechanisms underlying the relationship between PA and QoL are unclear. The purpose of this study was to determine whether the relationship between PA and QoL differs in younger and older cancer survivors and whether circadian rhythm (CR) mediates this relationship. We also explored the effect of the CR on QoL. The participants were 235 cancer survivors, comprising 143 younger and 92 older patients. Data were collected using the Taiwanese versions of the Physical Activity Scale for the Elderly and Short Form-36. The robustness and stability of the CR were measured using an actigraph. Mediation was tested using multiple mediation analyses. The CR mediated the relationship between PA and the physical domain of QoL in younger and older cancer survivors (23% and 59% mediating effects, respectively). The CR partially mediated the effect of PA on the mental dimension of QoL in older cancer survivors (36% mediating effect), but not in younger cancer survivors. Cancer survivors with a more robust CR had a significantly higher QoL, particularly in the physical functioning domain (d = 0.43, p < 0.001). The results provided evidence that the CR mediated the relationship between PA and QoL. Moreover, this mediating effect differed in younger and older cancer survivors. These results can serve as a reference for designing individualized PA programs for cancer survivors.

The effect of a community-based exercise intervention on symptoms and quality of life

BACKGROUND

Moderate-intensity physical activity in women with breast cancer has been reported to improve physical and psychological outcomes. However, initiation and adherence to a routine physical activity program for cancer survivors after therapy may be challenging.

OBJECTIVE

The purpose of this study was to determine the feasibility and effect of a community-based exercise intervention on physical and psychological symptoms and quality of life in breast cancer survivors.

METHODS

A 1-group pretest-posttest design was used to evaluate a thrice weekly, 4- to 6-month supervised exercise intervention on symptoms and quality of life. Data were collected at baseline and end of the intervention, using the Breast Cancer Prevention Trial Checklist, the Symptom Distress Scale, the Centers for Epidemiology Scale for Depression, and the Medical Outcomes Short Form.

RESULTS

There were 26 participants, with a mean (SD) age of 51.3 (6.2) years; most were married, well educated, and employed. The intervention was delivered at 3 community fitness centers, and adherence ranged from 75% to 98%. Vasomotor, musculoskeletal, and cognitive symptoms were common, but only muscle stiffness, fatigue, and depression significantly changed over time (P = .04, .05, and .01, respectively). Quality of life improved significantly in the areas of physical, emotional, and social function; pain; vitality; and mental health.

CONCLUSIONS

Providing an exercise intervention in the community where women live and work is feasible and improves physical, psychological, and functional well-being.

IMPLICATIONS FOR PRACTICE

Exercise is a key component of cancer rehabilitation and needs to be integrated into our standard care.

Socio-demographic, treatment-related, and health behavioral predictors of persistent pain 15 months and 7-9 years after surgery: a nationwide prospective study of women treated for primary breast cancer

The purpose of this study was to investigate and report prevalence and risk factors for persistent pain in breast cancer patients at 15 months and 7-9 years post surgery. A nationwide inception cohort study including 3343 women treated for primary breast cancer between 2001 and 2004, who returned a questionnaire 3 months post surgery. Socio-demographic and clinical information was obtained from registries. Questionnaire data on pain and health behaviors were obtained 15 months and 7-9 years post surgery. A total of 1905 women were eligible for analysis. At 15-month post surgery, 32.7 % reported pain "almost every day" or more frequently. At 7-9 years post surgery, the prevalence decreased to 20.4 %. Socio-demographic (young age, lower education, lower income, lower occupational status), treatment-related (being lymph node positive, axillary lymph node dissection (ALND), post-menopausal endocrine treatment), and health behavioral factors (smoking ≥ 10 cigarettes/day, obesity (BMI ≥ 30 and < 35), comorbidity, poor physical function) were significantly associated with pain at 15 months. Being physically active and moderate alcohol intake (<3 units/day) were negatively associated with pain. At 7-9 years post surgery, only ALND (OR:1.41, p = 0.03), post-menopausal endocrine treatment (OR:1.62, p = 0.01), poorer physical function (ORs:2.00-2.40, p = 0.003), and weight training (h/week) at 15 months (OR:1.10, p = 0.008) were significant predictors of pain when adjusting for age and pain 15 months post surgery. No socio-demographic predictors remained statistically significant. Younger age, lower socio-economic status, more invasive surgery, endocrine treatment, and adverse health behaviors emerged as risk factors for persistent pain. The influence of risk factors changed over time, suggesting a complex course of pain development and maintenance.

Physical inactivity and risk of poor quality of life among elderly cancer survivors compared to women without cancer: the Iowa Women's Health Study

PURPOSE

Few studies have examined lifestyle factors and quality of life (QOL) in cancer survivors compared to a cancer-free group. Compared to active cancer-free women, we examined the association between physical inactivity and QOL in elderly cancer survivors and similar-aged women without cancer.

METHODS

Participants included 1776 cancer survivors and 12,599 cancer-free women enrolled in the Iowa Women's Health Study in 1986 who completed the SF36 QOL assessment in 2004 (ages 73-88 years). The odds of poor QOL were computed for each SF36 subscale (>0.5 SD below mean score of cancer-free women) associated with physical inactivity (moderate-vigorous activity <once/week) between four groups based on the cross-classification of cancer history (no/yes) and physical inactivity (no/yes) (referent group = active cancer-free women).

RESULTS

Compared with the referent group, inactive cancer survivors were significantly more likely to report poor QOL for each SF36 subscale (odds ratios 1.8 to 4.7), independent of age, comorbidity, body mass index (BMI), and diet quality. The greatest odds for poor QOL occurred for general health, vitality, and physical function. These increased odds occurred regardless of whether survivors were inactive at both baseline (1986) and follow-up or became inactive sometime after baseline. Among physically active women, cancer survivors had similar QOL as cancer-free women.

CONCLUSION

These findings provide evidence on the importance of leisure-time physical activity in older women and support the need for interventions to help older women maintain or regain a physically active lifestyle.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors who remain or become physically active as they age report better mental and physical QOL.

Symptoms and Symptom Attribution Among Women on Endocrine Therapy for Breast Cancer

BACKGROUND

Adherence to adjuvant endocrine therapy (ET) influences breast cancer survival. Because ET side effects are frequently cited as reasons for nonadherence, understanding how perceptions and motivations in relation to ET are associated with symptom attribution can help promote timely symptom management.

MATERIALS AND METHODS

Participants were 2,086 breast cancer survivors recruited through the Army of Women registry who were current tamoxifen or aromatase inhibitor (AI) users. Participants reported whether they were bothered by each of 47 symptoms during the past month and whether they thought each symptom was related to taking ET. Frequencies of overall symptoms and symptoms attributed and misattributed to ET were calculated, and linear regression was used to assess sociodemographics, emotions, and illness perceptions as predictors of symptoms attributed to ET.

RESULTS

Women attributed a mean of 8.9 symptoms and misattributed a mean of 1.5 symptoms to ET. In the multivariable analysis, younger age, a more recent diagnosis, AI use (vs. tamoxifen), anxiety, depressive symptoms, more ET-related negative emotions, more concern about long-term ET use, and greater perceived ET necessity were independently associated with attribution of more symptoms to ET. More perceived ET necessity was associated with correctly attributing symptoms to ET, whereas higher depressive symptoms and more concern about ET use were associated with misattribution of symptoms to ET.

CONCLUSION

Given that many women perceive a range of symptoms as a consequence of ET, attention to these symptoms may reduce symptom burden and improve quality of life, potentially improving ET adherence and optimizing survival.

IMPLICATIONS FOR PRACTICE

Many breast cancer survivors on endocrine therapy (ET) experience a range of side effects while taking ET. Targeting potentially modifiable factors associated with attributing a greater number of symptoms to ET, including perceived need for ET, concerns about long-term ET use, negative emotions toward ET, and symptoms of anxiety and depression, may reduce symptom burden and improve quality of life.

Fit & strong! Promotes physical activity and well-being in older cancer survivors

INTRODUCTION

Physical activity reduces fatigue and depression while improving quality of life in cancer survivors. Exercise is generally considered safe and is recommended to survivors of all ages. Despite the high prevalence of cancer in the elderly, few studies address physical activity interventions targeting this older population. Fit & Strong! is an evidence-based physical activity program shown to improve level of physical activity, exercise-self-efficacy, and mood in older adults with osteoarthritis. This study tests the feasibility and short-term impact of the Fit & Strong! exercise program adapted for older cancer survivors.

METHODS

Participants were cancer survivors at least 50 years of age who were not on active treatment with intravenous chemotherapy or radiation. They participated in the 8-week Fit & Strong! program, which included three 90-min sessions per week; 60 min of group physical activity and 30 min of education. Education on osteoarthritis was removed from the Fit & Strong! program and replaced with relevant topics on cancer survivorship issues. Feasibility was measured by the ability to recruit and retain older cancer survivors. Pre and post-intervention surveys evaluated the effect of the intervention on physical activity and quality of life.

RESULTS

The study enrolled 72 cancer survivors to participate in an 8-week exercise program. The mean age of participants was 70. Over two-thirds (68%) of participants completed the program and with a mean attendance rate of 75% (18 of 24 sessions). No safety issues occurred. Improvements from baseline to post-intervention were observed for self-reported minutes of physical activity per week, self-efficacy for aerobic exercise, and symptoms related to depression and anxiety.

CONCLUSION

This study was successful in recruiting and retaining a population of older cancer survivors to participate in a group exercise program. Significant improvement in level of physical activity and mood suggests this evidence-based physical activity intervention can be adapted to promote health benefits in cancer survivors. Additional studies are necessary to confirm efficacy and assess long-term benefits.

Longitudinal study on the impact of physical activity on the symptoms of lung cancer survivors

PURPOSE

To examine the effect of physical activity on the physical and psychosocial symptoms of lung cancer survivors.

METHODS

A longitudinal design was used in this study. Participants were recruited from the chest and surgical departments of medical centers in Taiwan. The instruments used were the Godin Leisure-Time Exercise Questionnaire and the Taiwanese version of the M.D. Anderson Symptom Inventory.

RESULTS

In total, 185 survivors were followed up for 6 months (response rate 66%). Disturbed sleep was the most prevalent symptom in the participants. A generalized estimating equation (GEE) method was employed to analyze the relationships among intensity of physical activity, symptom severity, and symptom interference in the daily life of the participants. Regarding symptom severity, significant differences were observed in fatigue, drowsiness, and disturbed sleep between the participants who engaged in moderate physical activity and those who did not engage in any physical activity. Regarding symptom interference, the participants who engaged in light physical activity experienced a significantly lower level of symptom interference than did those with a sedentary lifestyle.

CONCLUSION

This is the first study to explore the role of physical activity in alleviating symptoms in lung cancer survivors by using the GEE method. The results suggest that physical activity plays an essential role in alleviating the physical and psychological symptoms of lung cancer survivors.

Review of the literature including research reports, review articles, and clinically based articles available through PubMed and CINAHL.

CONCLUSION

Minority women generally experience worse breast cancer outcomes despite a lower incidence of breast cancer than whites. A variety of factors contribute to this disparity, including advanced stage at diagnosis, higher rates of aggressive breast cancer subtypes, and lower receipt of appropriate therapies including surgery, chemotherapy, and radiation. Disparities in breast cancer care also extend into the survivorship trajectory, including lower rates of endocrine therapy use among some minority groups, as well as differences in follow-up and survivorship care.

IMPLICATIONS FOR NURSING PRACTICE

Breast cancer research should include improved minority representation and analyses by race, ethnicity, and socioeconomic status. While we cannot yet change the biology of this disease, we can encourage adherence to screening and treatment and help address the many physical, psychological, spiritual, and social issues minority women face in a culturally sensitive manner.
