Alternate Title

Soy-Based Meal Replacement in Helping Women With Stage I, Stage II, or Stage III Breast Cancer in Complete Remission Lose Weight. Note: The information about this trial has not been updated by the sponsor/principal investigator/lead organization. Cancer.gov cannot verify the accuracy of the information.

Basic Trial Information

Objectives

1. 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.
2. Assess the patient's ability to adhere to this intervention protocol.
3. 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).
4. Measure changes in health-related quality of life.

Entry Criteria

Disease Characteristics:

• 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

Prior/Concurrent Therapy:

• See Disease Characteristics
• No concurrent medications for weight loss
• No concurrent treatment for ER/PR-negative disease

Patient Characteristics:

• Female
• Menopausal status not specified
• No history of soy allergies
• No uncontrolled blood pressure
• No uncontrolled hyperthyroidism or hypothyroidism
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception
• No diabetes mellitus (type 1 or 2)

Expected Enrollment

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

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.
