Circulating Tumor DNA and Immunophenotyping as Potential Biomarkers With Regional Nodal Irradiation for Breast Cancer (NCT04308720)
Circulating Tumor DNA (ctDNA) and Immunophenotyping as Potential Biomarkers in Patients Undergoing Regional Nodal Irradiation for Breast Cancer
🩺 Plain-English Summary (8th-Grade Level)
This study will assess how radiation affects the patterns of circulating tumor deoxyribonucleic acid (ctDNA) and immune cells (T cells) during radiation treatment in patients with breast cancer. By better understanding how radiation therapy affects these markers (characteristic that is measured to see how well the body responds to a treatment for a disease) in the blood, researchers may better customize treatments for patients with breast cancer in the future.
