Is this trial a fit for you?

Likely a good fit

Adults with breast cancer eligible for breast-conserving surgery requiring lesion bracketing and sentinel lymph node biopsy.

Probably not a fit

Patients who do not require bracketing or sentinel node biopsy, or who have contraindications to Magtrace, may not benefit.

What this trial studies

In early-stage breast cancer, precise localization of the lesion and sentinel lymph node is crucial for complete tumor removal and accurate staging. This trial uses superparamagnetic iron oxide (Magtrace) for bracketing the lesion and guiding sentinel node localization during breast-conserving surgery. The approach aims to reduce reliance on radioactive materials and wires, potentially improving patient comfort and workflow. Eligible participants are those undergoing lumpectomy with planned bracketing and sentinel node biopsy, under the care of the King Faisal Specialist Hospital & Research Center. The study observes safety and practicality of the Magtrace bracketing technique in real surgical settings.

Why it matters

Potential benefit: If successful, patients could benefit from more convenient localization with fewer radioactive materials and improved surgical precision.

How similar studies have gone: Prior experiences with Magtrace and magnetic localization have shown promise, but broader validation in bracketing for breast-conserving surgery is still being explored.

Inclusion Criteria:

All patients with breast cancer undergoing breast conserving surgery requiring bracketing of the area of excision (as determined by the multidisciplinary tumor board) and a sentinel lymph node biopsy for axillary staging.

Exclusion Criteria:

1. Patients having mastectomy.
2. Patients unfit for breast conserving surgery due to inability to have adjuvant radiotherapy.
3. Patients requiring axillary clearance without sentinel node biopsy.
4. Patient undergoing breast conserving surgery without need for sentinel node biopsy.
5. Patient with metastatic breast cancer requiring palliative surgery for local control.
6. Patients not consenting for research.
7. Patient with allergy to Magtrace.
