Use of a Soy-Based Meal Replacement Weight Loss Intervention for Survivors of ER/PR Negative Breast Cancer


- Determine the ability to recruit survivors of estrogen receptor/progesterone receptor
(ER/PR)-negative stage I-III breast cancer to participate in a 3-month, soy-based,
meal-replacement (Almased®) weight loss intervention.

- Assess the patient's ability to adhere to this intervention protocol.

- Measure changes in anthropometrics (body weight, bioelectrical impedance, waist
circumference) and biomarkers (serum levels of glucose, insulin, highly specific
C-reactive protein, insulin-like growth factor, insulin-like growth factor binding
protein-3, lipids).

- Measure changes in health-related quality of life.

OUTLINE: This is a prospective, longitudinal, pilot study.

Patients undergo goal-oriented, cognitive-behavioral therapy comprising group counseling
weekly for 3 weeks and individual counseling once a month. Weight loss interventions include
behavioral techniques, dietary modification (using a portion-controlled diet and soy-based
meal-replacement [Almased®] once or twice daily), physical activity (≥ 15 minutes per day, 6
days a week), and social support. Weight loss is monitored weekly and patients complete
daily logs of dietary intake and physical activity. Therapy continues for 12 weeks.

Health-related quality of life is assessed at baseline and then weekly for 12 weeks.

Patients undergo blood draws at baseline and at 12 weeks for analysis of C-reactive protein,
glucose, insulin, insulin-like growth factor (ILGF), and ILGF-binding protein-3.

PROJECTED ACCRUAL: A total of 25 patients will be accrued for this study.
