- 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.
- Previously diagnosed stage I-III breast cancer currently in complete remission
- Completed treatment for breast cancer ≥ 6 months ago
- Free of disease at last clinic visit
- Body mass index ≥ 27
- Hormone receptor status
- Estrogen receptor (ER)/progesterone receptor (PR) negative

- No uncontrolled blood pressure
- No uncontrolled hyperthyroidism or hypothyroidism
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception

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

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
