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.

Weight Loss Intervention

Purpose African American women with breast cancer have higher cancer-specific and overall mortality rates. Obesity is common among African American women and contributes to breast cancer progression and numerous chronic conditions. Weight loss interventions among breast cancer survivors positively affect weight, behavior, biomarkers, and psychosocial outcomes, yet few target African Americans. This article examines the effects of Moving Forward, a weight loss intervention for African American breast cancer survivors (AABCS) on weight, body composition, and behavior. Patients and Methods Early-stage (I-III) AABCS were randomly assigned to a 6-month interventionist-guided (n = 125) or self-guided (n = 121) weight loss program supporting behavioral changes to promote a 5% weight loss. Anthropometric, body composition, and behavioral data were collected at baseline, postintervention (6 months), and follow-up (12 months). Descriptive statistics and mixed models analyses assessed differences between groups over time. Results Mean (± standard deviation) age, and body mass index were 57.5 (± 10.1) years and 36.1 (± 6.2) kg/m2, respectively, and 82% had stage I or II breast cancer. Both groups lost weight. Mean and percentage of weight loss were greater in the guided versus self-guided group (at 6 months: 3.5 kg v 1.3kg; P < .001; 3.6% v 1.4%; P < .001, respectively; at 12 months: 2.7 kg v 1.6 kg; P < .05; 2.6% v 1.6%; P < .05, respectively); 44% in the guided group and 19% in the self-guided group met the 5% goal. Body composition and behavioral changes were also greater in the interventionist-guided group at both time points. Conclusion The study supports the efficacy of a community-based interventionist-guided weight loss program targeting AABCS. Although mean weight loss did not reach the targeted 5%, the mean loss of > 3% at 6 months is associated with improved health outcomes. Affordable, accessible health promotion programs represent a critical resource for AABCS.
