Purpose: Breast cancer patients are at increased risk of developing comorbidities such as lymphedema, sarcopenia, osteoporosis and cardiovascular disease after breast cancer treatment. These complications contribute to a decrease in quality of life, cardiorespiratory fitness and muscle strength. Regular and long-term physical activity is an effective non-pharmacological strategy that can improve physical, psychological and social outcomes. The aim of our research was to evaluate the effect of various modes of an exercise intervention on physical performance, body composition, depression and autonomic nervous system in breast cancer survivors. Methods: 16 women after surgery with hormonal treatment enter the research. Thirteen of them completed the controlled, quasi-experimental study (54 ± 9 yrs, 164cm ± 6cm, 72 ± 12kg) and were divided into 3 groups according to their place of living: trained under supervision (n=5) (SUPERV), trained at home without supervision by videos (n=7) (HOME) and with no prescribed physical activity (n=4) (CON). Exercise intervention lasted 3 months and comprised of 60 min training units 3 × week (aerobic with resistant exercise in a 2 : 1 mode combined with regular weekly yoga and breathing exercises). The exercise intensity was set individually at 65–75% of HRR based on spiroergometry and was continuously controlled by heart rate monitors. The same principles applied to the HOME group, which, in addition to heart rate monitors, recorded frequency, length, HRmax, HRavg, and Borg scale of intensity perception. VO2max, BMI, fat mass, depression level (Beck’s depression inventory) and the power of the autonomic nervous system (total power and sympatho-vagal balance) were analyzed. For data evaluation we used descriptive statistics and Cohens d effect size. Results: 3 women dropped out of research because of medical reason. In all groups VO2max values increased. The largest increase in VO2max values was in SUPERV group by 36%, in HOME group by 20% and in CON group by 2%. Body weight decreased for groups SUPERV (˗1.2 kg) and CON (-0.1kg), for HOME group there was an increase (+0.2 kg). Body mass index decreased for SUPERV group (-0.4), for HOME and CON it increased (both +0.1). Total power decreased in SUPERV (-0.6) and HOME group (-0.2), in CON has not changed. The same results were achieved by the sympatho-vagal balance, only the CON group increased. Values from Beck’s depression inventory decreased for all groups, most for CON group. Conclusion: A 3-months of supervised and controlled exercise had a significant effect on physical fitness and body composition in comparison with non-supervised home-based physical intervention. Our results indicate that it is strongly advisable to apply a supervised exercise program to induce positive physiological changes in breast cancer survivors as part of aftercare.

Objective. Weight gain and bone loss are commonly reported in breast cancer survivors. The purpose of this pilot study is to assess feasibility and explore the effect of an aerobic weight-loaded exercise intervention on bone remodeling, weight, and body composition.Design. A one-group pre-posttest design was used to test a 16—24-week supervised walking exercise intervention among women within 2 years of menopause. Through Weeks 1—4, time and weight were progressively increased. By Week 5 and through the end of the intervention, a waist belt was loaded with 5 lb and participants spent 45 min on the treadmill 3 times/week. Bone remodeling was measured by serum biomarkers (N-terminal propeptides of type I collagen [NTX] and serum osteocalcin). Dual-energy absorptiometry scans assessed body composition. Data were collected at baseline and 16 and 24 weeks.Results. The majority of the 26 participants were married, well educated, and employed, with a mean age of 51.3 years (SD = 6.2). The high adherence (M = 88.2%, SD = 6.8) demonstrated feasiblity. There were no significant changes in serum osteocalcin (p = .67), serum NTX (p = .31), lean muscle mass (p = .08), or percent fat mass for the group as a whole (p = .14), but fat mass increased for women on adjuvant endocrine therapy (p = .04). The women maintained their weight.Conclusions. This novel exercise intervention for breast cancer survivors was feasible, and women otherwise at high risk for weight gain and bone loss maintained their weight and bone mass.

Purpose Accumulating data suggest that exercise may affect breast cancer risk and outcomes. Studies have demonstrated that high levels of insulin, often seen in sedentary individuals, are associated with increased risk of breast cancer recurrence and death. We sought to analyze whether exercise lowered insulin concentrations in breast cancer survivors. Methods One hundred one sedentary, overweight breast cancer survivors were randomly assigned either to a 16-week cardiovascular and strength training exercise intervention or to a usual care control group. Fasting insulin and glucose levels, weight, body composition, and circumference at the waist and hip were collected at baseline and 16 weeks. Results Baseline and 16-week measurements were available for 82 patients. Fasting insulin concentrations decreased by an average of 2.86 μU/mL in the exercise group (P = .03), with no significant change in the control group (decrease of 0.27 μU/mL, P = .65). The change in insulin levels in the exercise group seemed greater than the change in controls, but the comparison did not reach statistical significance (P = .07). There was a trend toward improvement in insulin resistance in the exercise group (P = .09) but no change in fasting glucose levels. The exercise group also experienced a significant decrease in hip measurements, with no change in weight or body composition. Conclusion Participation in an exercise intervention was associated with a significant decrease in insulin levels and hip circumference in breast cancer survivors. The relationship between physical activity and breast cancer prognosis may be mediated, in part, through changes in insulin levels and/or changes in body fat or fat deposition.

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.

Abstract Purpose The Trials within Cohorts (TwiCs) design aims to overcome problems faced in conventional RCTs. We evaluated the TwiCs design when estimating the effect of exercise on quality of life (QoL) and fatigue in inactive breast cancer survivors. Methods UMBRELLA Fit was conducted within the prospective UMBRELLA breast cancer cohort. Patients provided consent for future randomization at cohort entry. We randomized inactive patients 12–18 months after cohort enrollment. The intervention group (n = 130) was offered a 12-week supervised exercise intervention. The control group (n = 130) was not informed and received usual care. Six-month exercise effects on QoL and fatigue as measured in the cohort were analyzed with intention-to-treat (ITT), instrumental variable (IV), and propensity scores (PS) analyses. Results Fifty-two percent (n = 68) of inactive patients accepted the intervention. Physical activity increased in patients in the intervention group, but not in the control group. We found no benefit of exercise for dimensions of QoL (ITT difference global QoL: 0.8, 95% CI = − 2.2; 3.8) and fatigue, except for a small beneficial effect on physical fatigue (ITT difference: − 1.1, 95% CI = − 1.8; − 0.3; IV: − 1.9, 95% CI = − 3.3; − 0.5, PS: − 1.2, 95% CI = − 2.3; − 0.2). Conclusion TwiCs gave insight into exercise intervention acceptance: about half of inactive breast cancer survivors accepted the offer and increased physical activity levels. The offer resulted in no improvement on QoL, and a small beneficial effect on physical fatigue.

e12501 Background: Weight loss interventions are effective approaches to reduce body weight and alter serum biomarkers in breast cancer survivors, however the impact on breast tissue biomarkers is unknown. The Lifestyle, Exercise and Nutrition (LEAN) study was a randomized trial designed to test the effect of a weight loss intervention on body composition and breast tissue and serum biomarkers. Methods: Fifity-one women with a BMI ³ 25.0 kg/m2 diagnosed with breast cancer, who had completed chemotherapy and/or radiation therapy were randomized to weight loss intervention or usual care. Breast tissue biopsies from the unaffected breast, fasting serum samples, and body composition were measured at baseline and 6-months. Ki67, insulin receptor (IR), CD68 and CD163 were measured by Automated Quantitative Analysis (AQUA) method. Mean baseline to 6-month changes were compared using ANCOVA adjusting for baseline values. Results: Pre- and post-intervention biopsies were conducted in 49 and 42 women respectively, with both pre- and post- epithelial tissue available from 25 women; epithelial tissue was unavailable in the remaining 66 women. Women were 56.8 ± 8.9 years old, diagnosed 3.3 + 3.8 years prior, primarily Stage I breast cancer (54%), with a BMI of 32.8 ± 6.0 kg/m2. At baseline, breast tissue levels of IR were inversely associated with both percent body fat (r = -0.47, p = .03) and serum insulin levels (r = -0.45, p = .04); serum insulin levels were inversely associated with CD68 (r = -0.47, p = .03). Significant between-group biomarker changes are presented in Table 1. At month 6, loss in percent body fat was associated with increased IR (r = -0.42, p = .05). Increased CD68 breast tissue expression was associated with reductions in serum levels of CRP (r = -0.49, p=0.02). There was no significant effect of the intervention on IR expression or Ki67 (p>0.10). Conclusions: Breast tissue biopsies are feasible to collect in a clinical research setting among breast cancer survivors. A 6-month weight loss intervention led to decreased levels of CD163 in breast tissue and serum levels of leptin, and increased serum levels of adiponectin among breast cancer survivors. At baseline and month 6, changes in breast tissue biomarkers were favorably associated with serum biomarkers and body composition. Future confirmation is required to confirm the added benefit of tissue biomarkers beyond serum as an endpoint for lifestyle interventions among breast cancer survivors.
