About this study
Promoter region hypermethylation of tumor suppressor genes is one the earliest molecular events in malignant transformation and is readily detectable in apparently normal benign breast epithelium adjacent to breast cancers. The investigators hypothesize that DNA methylation of certain genes occurs as a field change in benign breast tissue that is at high risk for malignant transformation, and as such, can be exploited for tissue-based breast cancer risk stratification. Additional work is required to identify new DNA methylation markers potentially useful for periareolar fine needle aspiration (RP-FNA)-based breast cancer risk stratification, to determine whether these markers are methylated more frequently in benign samples from women who develop breast cancer, to determine whether assessment of these markers is reproducible, to determine whether tamoxifen reduces DNA methylation, and to better understand the pattern of DNA methylation in benign samples from unselected healthy control populations. Each of these objectives contributes to advancement of a clinically useful RP-FNA-based breast cancer risk stratification test.
In addition, identification of genes that are preferentially methylated in estrogen receptor (ER) negative breast cancer will provide clues to the underlying biology responsible for this aggressive form of breast cancer. This knowledge may lead to the discovery of the causes of ER negative breast cancer, approaches for recognizing women at increased risk for this type of breast cancer, and approaches for reducing this risk.
This study seeks to identify patterns of DNA methylation in benign breast epithelial cells associated with an increased risk for breast cancer with a focus on ER negative breast cancer.

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer, run by University of Texas Southwestern Medical Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
DNA methylation (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2016.
