Comparing ICG and Blue Patent for Axillary Dissection in Breast Cancer

ICG vs Blue Patent as a Tracer in the Performance of TAD in Patients With cN1 Breast Carcinoma After Neoadjuvant Chemotherapy

Observational Hospital Universitari de Bellvitge · NCT06339658

This study is testing whether a special dye called indocyanine green (ICG) works better than the traditional blue dye during surgery to remove lymph nodes in breast cancer patients who have already had chemotherapy.

What this trial studies

This observational study aims to validate the use of indocyanine green (ICG) as a tracer during targeted axillary dissection (TAD) in patients with clinically node-positive (cN1) breast carcinoma following neoadjuvant chemotherapy. It will prospectively collect standardized clinical, imaging, surgical, and pathological data to assess the effectiveness of ICG compared to the traditional Blue Patent method. Participating surgeons and radiologists will undergo training to ensure adherence to standardized procedures, and data quality will be maintained through electronic case report forms and regular inter-institutional meetings.

Who should consider this trial

Good fit: Ideal candidates are patients with clinically node-positive breast cancer who have undergone neoadjuvant chemotherapy.

Not a fit: Patients with contraindications for ICG use or evidence of disease progression after neoadjuvant treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy and outcomes of axillary dissection in breast cancer patients.

How similar studies have performed: Other studies have shown promising results with ICG as a tracer in similar surgical contexts, indicating potential for success.
