New magnetic tracer aims to reduce side effects in breast cancer lymph node biopsy
NCT ID NCT06610539
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a magnetic tracer called Magtrace for sentinel lymph node biopsy in women with breast cancer who are having a lumpectomy. The main goal is to see how often skin discoloration happens and how it affects patients' quality of life. Researchers will follow 184 participants for up to 24 months to track outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Magtrace (magnetic tracer)
- What this could lead to
- If successful, this could show that Magtrace is a safe and effective alternative to standard dyes or radioactive tracers for lymph node mapping, with manageable side effects.
- What could go wrong
- This is a small, early-phase study (184 participants) focused on side effects and patient experience, not on curing cancer. Skin discoloration may still be a common issue, and results may not apply to all breast cancer patients.

Inclusion Criteria: * Patient is willing and able to give informed consent for participation in the study * Patient is aged 18 years or older at the time of consent * Patients undergoing planned breast conserving surgery (for example, lumpectomy or partial mastectomy) and SLNB with Magtrace Exclusion Criteria: * The patient is pregnant or lactating * The patient has had prior breast radiation to the ipsilateral breast * The patient has clinical or radiological evidence of metastatic cancer including palpably abnormal or enlarged lymph nodes * The patient has recevied a Feraheme (ferumoxytol) injection within the past 6 months * The patient has intolerance or hypersensitivity to iron or dextran compounds or to Magtrace * The patient has iron overload disease * The patient has discoloration on the breast (such as tattoo, birthmark, tanning, rash etc.), that in the Investigator's opinion, could impact the clinical trial results, specifically the assessment of any skin discoloration, or plans to have a tattoo on the breast post-operatively.
