Prospective Analysis of Patients at Risk for Breast Cancer-Related Lymphedema (BCRL) Using Indocyanine Green (ICG) Fluoroscopy and SPYTM Angiography

This clinical trial assesses the change in lymphatic structure from placement of an intravenous (IV) line and fluid administration using a diagnostic agent, indocyanine green (ICG), with SPY (Trademark) angiography in breast cancer patients at risk for breast cancer-related lymphedema (BCRL). Patients that are diagnosed with breast cancer with lymph node involvement often undergo treatment that includes surgery to remove the axillary nodes and radiation. Unfortunately, this procedure increases the incidence of BCRL in the surgical arm, as well as other problems including heaviness of the arm, fibrotic skin changes, and an increase in infection risk. Because of these symptoms, venipuncture (blood draw) is often avoided in these arms. Researchers want to show that placement of an IV line and fluid administration in patients at risk for BCRL will indeed not alter the lymphatic structure of the arm and will not change the incidence of BCRL by administering indocyanine green (ICG) dye to patients and assessing their arm lymphatics. ICG is a fluorescent dye that is able to be visualized by the SPY angiography imaging system as it travels through the lymphatic system, allowing researchers to assess how well blood flows throughout the body. Receiving ICG and undergoing SPY angiography may be effective in showing that placement of an IV and fluid administration in breast cancer patients at risk for BCRL will not alter the lymphatic structure of their arm and will not change the incidence of BCRL.
