A Retrospective Multicentric Clinical Study Comparing Radioguided Occult Lesion Localization (ROLL) and Magnetic Seed in the Intraoperative Localization of Non-palpable Breast Lesions During Breast Conservative Surgery.

Observational Istituti Clinici Scientifici Maugeri SpA · NCT05942092

This study is testing whether a new way to locate breast tumors using ROLL or magnetic seeds helps patients have better surgery outcomes and less chance of the cancer coming back.

What this trial studies

This study compares two techniques, ROLL and magnetic seed localization, for preoperative localization of non-palpable breast lesions in patients undergoing breast-conserving surgery. The aim is to determine which method provides better outcomes in terms of complete tumor resection and minimizing the risk of local recurrence. By evaluating the effectiveness of these techniques, the study seeks to enhance surgical precision and patient comfort during the procedure.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 to 85 with non-palpable breast lesions who are scheduled for breast-conserving surgery.

Not a fit: Patients with benign lesions or those who have undergone breast tumor localization with clips for neoadjuvant chemotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and reduce the need for additional surgeries in breast cancer patients.

How similar studies have performed: While wire guided localization has been the gold standard, this study explores newer techniques, indicating a novel approach in the field.
