Condition: Breast Neoplasms · Lymphedema Due to Radiation · Sponsor: Inah Kim
The goal of this observational study is to learn how the lymphatic system changes before and after radiotherapy in female patients with breast cancer. The study aims to understand early lymphatic changes that may lead to breast-cancer-related lymphedema (BCRL) and to help identify patients who might benefit from early preventive rehabilitation. The main questions it aims to answer are: How does lymphatic flow and vessel function change after radiotherapy, as measured by indocyanine green (ICG) lymphography? Can early imaging changes on ICG lymphography predict later swelling or lymphedema symptoms in the arm? There is no comparison or treatment group, since all participants will receive radiotherapy as part of their standard breast cancer care. Participants will: Undergo ICG lymphography before radiotherapy and again within 4-6 weeks after completing radiotherapy Receive a small injection of ICG dye under the skin and have near-infrared imaging to visualize lymphatic flow Complete follow-up assessments (for some participants) at 3, 6, or 12 months to monitor long-term lymphatic changes Continue their usual standard medical and rehabilitation care throughout the study This study will include 40 female participants, aged 18 years or older, who have been diagnosed with stage I-III breast cancer and are scheduled for postoperative radiotherapy. Participants with a history of lymphedema, prior radiotherapy, severe organ disease, or known ICG/iodine allergy will not be in…
