Pilot study of the effect of weight loss on breast tissue and blood biomarkers in women at increased risk for breast cancer
Investigating the Effects of Weight Loss from Bariatric Surgery on Breast Cancer Biomarkers and Breast Density
Brief description of study.
The purpose of this study is to see the effects that weight loss after bariatric surgery might have on certain breast cancer biomarkers and breast density.
Detailed description of study
The purpose of this study is to investigate the effect of dramatic weight loss secondary to bariatric surgery on biomarkers of breast cancer tissue and blood as well as on imaging in women at elevated risk for breast cancer.
Eligibility of study
You may be eligible for this study if you meet the following criteria:
- Conditions: breast cancer,obesity,weight loss,cancer,oncology
-
Age: 18 years - 75 years
-

Must be willing to provide a core tissue biopsy at baseline and with repeat tissue collection after 2 weeks and 12 months post-bariatric surgery
ECOG Performance Status of 0 - 1 within 28 days of registration
Patients must be planning to undergo primary bariatric surgery (no revisions)
Exclusion Criteria

Weight cannon exceed 500 lbs. at the time of imaging
Known allergy to gadolinium which us used for MRI contrast
This study investigates the effects of weight loss after bariatric surgery on breast cancer biomarkers and breast density. Biomarkers are substances in the body that can indicate a disease or condition, and breast density refers to the amount of fibrous or glandular tissue compared to fatty tissue in the breasts. The study focuses on women who are at an elevated risk for breast cancer.
Participants will undergo procedures including a core tissue biopsy, which involves taking a small sample of breast tissue for testing. This will happen at the start of the study, and again two weeks and twelve months after the surgery. Blood samples and imaging tests will also be conducted to observe changes in breast cancer risk factors.
- Who can participate: Women who are at an elevated risk for breast cancer and are planning to undergo primary bariatric surgery can participate. Participants must be willing to provide tissue samples, meet specific health criteria, and have no known allergies or weight limitations that could affect the study.
- Study details: Participants will provide tissue samples and undergo imaging tests. A placebo is not used in this study.
