Objective. Breast cancer survivors are highly sedentary, overweight, or obese, which puts them at increased risk for comorbid chronic disease. We examined the prevalence of, and changes in, metabolic syndrome following 6 months of an aerobic exercise versus usual care intervention in a sample of sedentary postmenopausal breast cancer survivors.Design and Methods. 65 participants were randomized to an aerobic exercise intervention (EX) (n=35) mean BMI 30.8 (±5.9) kg/m2or usual care (UC) (n=30) mean BMI 29.4 (±7.4) kg/m2. Metabolic syndrome prevalence was determined, as well as change in criteria and overall metabolic syndrome.Results. At baseline, 55.4% of total women met the criteria for metabolic syndrome. There was no statistically significant change in metabolic syndrome when comparing EX and UC. However, adhering to the exercise intervention (at least 120 mins/week of exercise) resulted in a significant (P=.009) decrease in metabolic syndromez-score from baseline to 6 months (-0.76±0.36) when compared to those who did not adhere (0.80±0.42).Conclusions. Due to a higher prevalence of metabolic syndrome in breast cancer survivors, lifestyle interventions are needed to prevent chronic diseases associated with obesity. Increasing exercise adherence is a necessary target for further research in obese breast cancer survivors.

Risk Of Cancer

TPS9648 Background: Current evidence suggests that breast cancer treatments such as chemotherapy lead to excessive weight gain, fatigue, physical inactivity, and negative alterations in components of metabolic syndrome (MetS). MetS is associated with increased risk of cancer recurrence, cardiovascular diseases and type 2 diabetes, and is defined by visceral adiposity, insulin resistance, hyperglycemia, hyperinsulinemia, low serum high-density lipoprotein cholesterol, and hypertension. MetS is highly prevalent and present in 25% of American and European adults and higher in minorities. Given that chemotherapy for breast cancer induces many of the components of MetS, an effort to offset these consequences of cancer therapy using exercise/lifestyle intervention could improve breast cancer, cardiovascular and endocrine outcomes. Methods: Our study seeks to determine whether a 16-week exercise intervention induces changes in prognostic components of MetS (waist circumference, blood pressure, serum levels of glucose, insulin, lipids, C-reactive protein and HbA1c) among breast cancer survivors if initiated within 3 months of completion of chemotherapy or radiation therapy. We are currently recruiting women diagnosed with Stage I-III breast cancer from the USC Norris Comprehensive Cancer Center and Los Angeles County Hospital, which cares for a high proportion of minority/underserved patients. Participants are randomized to either the Control (usual care) or the Exercise group. The Exercise group participates in aerobic and resistance exercise sessions 3 times a week for 16 weeks supervised by an exercise specialist at the USC Clinical Exercise Research Center. At baseline and following the study period, all participants are tested for MetS components, muscle strength, body composition, bone density, cardiorespiratory fitness, quality of life, fatigue and shoulder function. We will recruit an additional 85 patients (at present time n=15) over the next 3 years. It is expected that this intervention will improve components of MetS and physical fitness in breast cancer survivors when compared to the Control group, thus defining intervention and biomarker variables for more definitive trials.

AbstractMOTS-c is a mitochondrial derived peptide with exercise mimetic activity that elicits beneficial effects on metabolism and exercise capacity. Furthermore, MOTS-c effects in humans are affected by race, potentially via ethnic-specific mtDNA variations. Women treated for breast cancer are at an increased risk for cardiovascular disease, diabetes and obesity, due to side effects of cancer-treatments. We conducted a secondary analysis of the effects of a 16-week aerobic and resistance exercise intervention on MOTS-c in Hispanic and Non-Hispanic White breast cancer survivors (BCS). BCS (Stage I–III) were randomized to exercise or standard care. The intervention promoted aerobic and resistance exercise for 16 weeks. MOTS-c was analyzed in fasting plasma using an in-house ELISA. Within and between group differences were assessed by paired t-test and repeated measures ANOVA. Pearson’s correlation was computed to assess the association between MOTS-c and metabolic biomarkers at baseline and post-exercise. Twenty-five Hispanic-BCS and 24 non-Hispanic White BCS were included. Hispanic BCS were younger, of greater adiposity, had higher stage cancers, and had worse metabolic profiles at baseline compared to non-Hispanic White BCS (p < 0.001). Post-exercise, MOTS-c levels significantly increased when compared to baseline and the usual care group among non-Hispanic White BCS (p < 0.01) but not among Hispanic breast cancer survivors (p > 0.01). Post-exercise levels of MOTS-c among non-Hispanic White BCS were significantly associated with reductions in fat mass, body weight, HOMA-IR, CRP, and an increase in lean mass (p < 0.01). A 16-week aerobic and resistance intervention increased MOTS-c levels among non-Hispanic White BCS.

The Impact

Purpose Arthralgia occurs in up to 50% of breast cancer survivors treated with aromatase inhibitors (AIs) and is the most common reason for poor AI adherence. We conducted, in 121 breast cancer survivors receiving an AI and reporting arthralgia, a yearlong randomized trial of the impact of exercise versus usual care on arthralgia severity. Patients and Methods Eligibility criteria included receiving an AI for at least 6 months, reporting ≥ 3 of 10 for worst joint pain on the Brief Pain Inventory (BPI), and reporting < 90 minutes per week of aerobic exercise and no strength training. Participants were randomly assigned to exercise (150 minutes per week of aerobic exercise and supervised strength training twice per week) or usual care. The BPI, Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index, and Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire were completed at baseline and at 3, 6, 9, and 12 months. Intervention effects were evaluated using mixed-model repeated measures analysis, with change at 12 months as the primary end point. Results Over 12 months, women randomly assigned to exercise (n = 61) attended 70% (± standard deviation [SD], 28%) of resistance training sessions and increased their exercise by 159 (± SD, 136) minutes per week. Worst joint pain scores decreased by 1.6 points (29%) at 12 months among women randomly assigned to exercise versus a 0.2-point increase (3%) among those receiving usual care (n = 60; P < .001). Pain severity and interference, as well as DASH and WOMAC pain scores, also decreased significantly at 12 months in women randomly assigned to exercise, compared with increases for those receiving usual care (all P < .001). Conclusion Exercise led to improvement in AI-induced arthralgia in previously inactive breast cancer survivors.

244 Background: Current literature suggests that weight gain during treatment for breast cancer is associated with a poorer prognosis and an increased risk of developing secondary health problems such as the metabolic syndrome (MetSyn). Physical activity (PA) can alter features of the MetSyn and improve body composition by reducing abdominal adiposity. We report metabolic results of a prospective randomized controlled trial (PEACH trial; Walsh JM, et al. [2010] BMC Cancer. 10[42]) which examines the effect of an exercise intervention on the metabolic risk profile of breast cancer survivors 2-6 months post chemotherapy. Methods: All subjects gave written informed consent and were randomized to an 8-week, twice weekly aerobic exercise intervention programme or a usual care control group consisting of routine medical advice about PA. The five clinical features of the MetSyn were measured: waist circumference (WC), resting blood pressure (BP), triglycerides, high-density lipoprotein cholesterol (HDL-C) and fasting glucose. Insulin resistance was estimated by the homeostatic model assessment (HOMA). Statistical analysis was carried out using independent sample t-tests with significance set at p < 0.05. Results: Twenty-six breast cancer survivors participated (mean (± SD) age 48.13 (8.75) years). At baseline, 50% (n = 13) of subjects were overweight and 23.1% (n = 6) were obese, with 73.1% (n = 19) centrally obese. 34.6% (n = 9) of subjects were classified with the MetSyn. There were no significant differences between groups at baseline. Intention-to-treat analysis showed no significant changes, however, analysis of those who adhered to > 70% of the supervised exercise intervention showed a significant improvement in WC when compared to the control group (p < 0.05). Conclusions: Results show that an 8-week aerobic exercise intervention significantly reduced WC but did not modify other features of the MetSyn. The decrease in WC demonstrated by this short intervention may have important implications in terms of improving survival and the metabolic risk profile of breast cancer survivors. Final follow-up assessments are ongoing and will enable change in WC over time to be evaluated further.

Objective cancer-related fatigue(CRF) is the most commonly reported and most distressing symptom in cancer patient.The purpose of this study was to review the effect of exercise intervention on cancer-related fatigue in breast cancer survivors. Methods From 1998 to 2018 in Chinese and English literature of Wanfang Database, Pubmed, SportDiscus and Springer databases, picked out the randomized controlled trials which up to standard. Keywords cancer, exercise, fatigue, etc. were used for systematic search and tracking. 12 experiments were reviewed to analyze the effect differences between exercise intervention and exercise-related fatigue. Results Most interventions use aerobic exercise as the primary form of exercise. Generally, exercise interventions are effective for cancer-related fatigue, but some findings are not. Many studies have shown that moderate intensity aerobic exercise has a significant effect on cancer-related fatigue, with 50-70% heart rate reserve and 3-5 times of exercise per week for at least 30 minutes each time. Exercise methods mainly include walking, yoga, cycling and tai chi. Firstly, Supervised aerobic exercise was statistically more effective than conventional care in improving CRF among breast cancer survivors. It has been shown that group-based, supervised exercise produces positive psychosocial‘side-effects’ due to social interactions, improved self-efficacy, and attention from a trainer. Secondly, Cancer fatigue is divided into acute and chronic fatigue, 18 weeks of exercise intervention can reduce the short-term fatigue, at 36 weeks, baseline levels of fatigue index responses and contrast on the issue of the multivariate statistics. Thirdly, usual-care group were reported that they had been actively engaged in regular exercise before study enrollment. During the exercise intervention, most studies on the control ways are according to the daily life or to take care of, but studies have reported, before intervention, to a high level of 40% in the control group often exercise, exercise also as usual during the intervention, which causes the control to the baseline level is higher, but the intervention group and control group will be difference, no significant difference, lead to the result is invalid. Conclusions First, the exercise intervention of cancer-related fatigue needs to be supervised; second, the exercise intervention is effective for short-term cancer-related fatigue; third, the daily exercise level of the control group will affect the intervention effect.

Abstract Background: Breast cancer survivors have double the risk of mortality from cardiovascular disease than age-matched women without a cancer history. Reynolds risk score (RRS) is a validated algorithm for the assessment of cardiovascular disease risk. This secondary analysis sought to examine the effects of a 16-week aerobic and resistance exercise intervention on RRS in overweight or obese breast cancer survivors. Methods and Results: One hundred overweight or obese (BMI>25kg/m2) breast cancer survivors were randomized to exercise or usual care. The exercise group underwent aerobic and resistance exercise sessions for 16 weeks. RRS was calculated using a validated equation. Group differences in mean change for RRS were evaluated using repeated-measures analyses of variance. Post-intervention, RRS was significantly reduced (7.9±0.9% to 1.0±0.5%, p<0.001) in the exercise group compared to a significant increase (9.0±0.8% to 11.6±1.2%; p=0.002%) in the usual care group (P<0.01). RRS was significantly reduced in exercise vs usual care (between group difference, -10.6; 95% CI, -16.3 to -7.4; p<0.001). Conclusion: A 16-week aerobic and resistance exercise intervention is an effective approach to reduce the risk of cardiovascular disease in breast cancer survivors. Exercise during cancer survivorship should be considered to reduce the risk for cardiovascular disease risk in overweight women breast cancer survivors.Trial registration: ClinicalTrials.gov: NCT01140282.

Abstract Background Postmenopausal bone fracture's have been proposed as a marker of lifetime estrogen exposure and have been associated with decreased risk of breast and endometrial cancer. It is plausible that prediagnostic fractures may be related to survival of estrogen-sensitive cancers. Methods We evaluated a cohort of breast (n = 6411), endometrial (n = 1127), and ovarian (n = 658) cancer cases diagnosed between 1992 and 2010 while participating in the Women’s Health Initiative. Postmenopausal fracture history was assessed from baseline reports of fractures after age 55 years and incident fractures that occurred at least one year prior to cancer diagnosis during study follow-up. Using Cox regression, we compared women with and without a history of fractures with respect to overall and cancer-specific survival. Estimates were adjusted for participant factors, including hormone therapy use; hormone receptor status was not included in our analysis. Results Among women with breast cancer, a history of prediagnostic fractures at any site was associated with poorer overall survival (hazard ratio [HR] = 1.22, 95% confidence interval [CI] = 1.05 to 1.43). A history of hip, forearm, or spine fractures, or hip fracture alone, was associated with increased risk of mortality (HR = 1.26, 95% CI = 1.01 to 1.58, and HR = 2.05, 95% CI = 1.27 to 3.32, respectively). Fracture history was associated neither with cancer-specific survival among breast cancer survivors, nor with overall or disease-specific mortality among endometrial and ovarian cancer survivors. Conclusions Postmenopausal breast cancer patients with a history of fractures, especially of the hip, are more likely to die of any cause than breast cancer survivors without a fracture history. Identifying and intervening in fracture risk factors should be standard of care for all women diagnosed with breast cancer.
