The Robot-LVA Study: Robot-assisted Microsurgical Lymphaticovenous Anastomosis in Breast Cancer-related Lymphedema

This study tests whether robot-assisted microsurgery can better treat arm swelling (lymphedema) that develops after breast cancer treatment. Lymphedema happens when the lymphatic drainage system is damaged during cancer surgery or radiation. A procedure called lymphaticovenous anastomosis (LVA) creates tiny connections between lymphatic vessels and veins to restore drainage — and this study tests a robotic-assisted version to see if it offers better precision than conventional microsurgery. **You may be eligible if...** - You are a woman who has been treated for early-stage breast cancer - You have early-stage lymphedema of the arm (ISL stage 1 or 2 — meaning there is swelling that may or may not resolve with elevation) - Your affected arm is more than 10% larger than the other arm - Only one arm is affected **You may NOT be eligible if...** - You are male - Your lymphedema is stage 3 (severe, with hardened tissue) - You are currently receiving breast cancer treatment - Your breast cancer has spread to distant parts of the body - You have had a previous LVA procedure in the last 10 years - You have an allergy to indocyanine green (a dye used in imaging) - Your lymphatic system is no longer viable on imaging Talk to your doctor to see if this trial is right for you.
