Studying Changes to ctDNA During Radiation Therapy in DCIS and Stage I-IV Breast Cancer

Circulating Tumor DNA and Immunophenotyping as Potential Biomarkers in Patients Undergoing Regional Nodal Irradiation for Breast Cancer Scientific Title

Purpose
To study how radiation therapy affects ctDNA and the immune system and if ctDNA can predict disease progression.
Who is this for?
People diagnosed with DCIS, stage I, stage II, or stage III breast cancer who will receive radiation therapy after surgery. You may also enroll if you have metastatic (stage IV) breast cancer with no more than three metastases that you plan to treat with radiation therapy.    Full eligibility criteria
