Signature Development and Validation Protocol for an Epigenetic Assay in Diagnosing Breast Cancer

Signature Development and Validation Protocol for an Epigenetic Assay in Diagnosing Breast Cancer

The purpose of this research study is to test a new process for diagnosing breast cancer by examining changes to your DNA that can be detected from a blood test. The information we learn by doing this study could potentially help people in the future.

Participants in this study will have blood samples collected, have their medical records reviewed by study personnel and fill out questionnaires at different time points during the study. Blood sample collection will occur during normal routine clinic visits. Participation in this study will last approximately 5 years.

This clinical testing protocol outlines the validation process for an epigenetic assay targeting host peripheral blood cell and the associated host DNA methylation signatures designed to diagnose breast cancer. The overall protocol process will involve three distinct stages representing three patient cohorts with up to 150 subjects per cohort across 3 populations of patients. Cohort one will act as signature development phase; cohort two will act as signature finalization phase; and cohort three will act as a validation cohort phase. Each cohort with include the following patient populations with up to 50 patients per population:

1. Breast cancer, NO chemotherapy. Includes patients treated with surgical resection and/or radiation therapy and/or endocrine therapy
2. Breast cancer who have received chemotherapy. Includes all stages including remission
3. At risk group (patients at increased risk for breast cancer followed in a high risk breast program)

Inclusion Criteria:

• 18 years old or older
• Patient of UMMS
• Willing and able to consent to study procedures listed in the protocol
• Ability to speak and understand English

Exclusion Criteria:

• Younger than 18 years old
• Patient not cared for at UMMS
• Unable to consent to study procedures listed in the protocol
• Unable to speak or understand English
