Comparing two types of radiation therapy for breast cancer patients

Official title: A Multicenter Randomized Controlled Phase III Study of Medial vs. Entire Supraclavicualr Lymph Node Radiation Therapy for Patients With Pathologically Positive Axillary Lymph Node and High Risk of Recurrence After Breast Cancer Surgery

Run by Fudan University · NCT05059379 · Data updated 2026-11-12

This study is testing which type of radiation therapy works better for breast cancer patients with positive lymph nodes to help them stay cancer-free after surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with newly diagnosed invasive breast cancer who have undergone surgery and have positive lymph nodes.

Probably not a fit

Patients with early-stage breast cancer or those who have not undergone surgery may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase III trial investigates the effectiveness of medial versus entire supraclavicular lymph node radiation therapy in patients with invasive breast cancer who have positive lymph nodes and are at high risk for recurrence after surgery. Patients will be randomized into two groups: one receiving medial supraclavicular radiation and the other receiving entire supraclavicular radiation. The primary objective is to evaluate disease-free survival, while secondary objectives include overall survival, recurrence rates, and assessment of radiation-related toxicities and quality of life. The trial aims to clarify the optimal radiation approach to improve patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved disease-free survival and overall survival for breast cancer patients at high risk of recurrence.

How similar studies have gone: Previous studies have shown varying results regarding the effectiveness of different radiation techniques, making this approach both relevant and necessary for further investigation.
