Women's Healthy Eating and Living Study

Breast Cancer Clinical Trial

Official title: Dietary Intervention in Women Who Have Been Treated For Stage I, Stage II, or Stage III Breast Cancer: Women's Healthy Eating and Living (WHEL) Study

Status Completed

Clinical Trial Summary

RATIONALE: Dietary fats, fruits, vegetables, and fiber may affect the risk of breast cancer recurrence.

PURPOSE: Randomized clinical trial to determine the effectiveness of a diet rich in vegetables, fruit, and fiber and low in fat in women who have been treated for stage I, stage II, or stage III breast cancer.

Clinical Trial Description

OBJECTIVES: I. Determine whether a diet rich in vegetables, fruit, and fiber and low in fat is associated with a longer breast cancer event-free interval in breast cancer survivors. II. Motivate an intervention group of breast cancer survivors to adopt and maintain a dietary pattern that is rich in vegetables, fruit, and fiber and low in fat. III. Demonstrate that the intervention can produce significant changes in circulating carotenoid and estrogen biomarkers compared to a healthy control diet. IV. Test whether the probability of a secondary cancer event is associated with change in self-reported dietary intake, circulating carotenoid concentrations, and circulating estrogen concentrations.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age (under 55 vs 55 and over at time of diagnosis), stage of tumor (stage I and at least 1 cm vs stage II/IIIA), and clinical site. Patients are randomized to one of two healthy dietary regimens: Arm I: Patients are taught to follow a dietary pattern that will produce significant changes in circulating carotenoid and estrogen biomarkers. Arm II: Patients are assigned to follow dietary guidelines established by the National Cancer Institute and the USDA. All patients participate in 24 hour dietary recalls, cooking classes, as well as complete several questionnaires, at baseline and then at 12, 24 or 36, 48, and 72 months; a randomly selected 50% sample participate in recall at 6 months. Patients are followed by telephone every 6 months for an average of 6 years.

PROJECTED ACCRUAL: A total of 3,000 women will be accrued for this study within 5 years. ;
