Mapping lymphatic drainage pathways in women with breast cancer

Variable Anatomy and Function of the Arm's Alternate Lymphatic Pathway

Observational Beth Israel Deaconess Medical Center · NCT05253352

This study is trying to see if differences in lymphatic pathways in healthy women and breast cancer survivors can help predict who might develop lymphedema after treatment.

What this trial studies

This study evaluates the anatomy of the lymphatic system pathways in healthy women and breast cancer survivors who did not develop lymphedema after treatment. Using advanced imaging techniques like indocyanine green lymphography and SPECT/CT, the researchers aim to identify variations in the Mascagni-Sappey pathway that may influence the risk of developing lymphedema. The goal is to better understand these anatomical differences and potentially predict which women are at higher risk for lymphedema. This observational study will involve participants who meet specific eligibility criteria related to their breast cancer treatment history.

Who should consider this trial

Good fit: Ideal candidates are women who have undergone breast cancer treatment with axillary lymph node dissection and are at least 18 years old.

Not a fit: Patients with a history of lymphedema, bilateral lymph node surgery, or other specified exclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved risk assessment and management strategies for women at risk of developing lymphedema after breast cancer treatment.

How similar studies have performed: While this approach is innovative, similar studies have not been extensively documented, indicating that this may be a novel investigation into lymphatic anatomy.
