1 ml Magtrace for sentinel lymph node biopsy in people with breast cancer

Official title: A Prospective Open Label Study of Patient Reported Outcome Measures and Efficacy Following the Use of 1ml Magtrace® for Sentinel Lymph Node Biopsy in Breast Cancer Patients Undergoing Lumpectomy

Run by Endomagnetics Ltd. · NCT06610539 · Data updated 2026-11-12

This study will try to find how often Magtrace causes skin discoloration and whether it reliably finds sentinel lymph nodes in people having breast-conserving surgery for breast cancer.

Is this trial a fit for you?

Likely a good fit

Adults (18+) who can consent and are scheduled for breast-conserving surgery with sentinel lymph node biopsy using Magtrace are ideal candidates.

Probably not a fit

People who are pregnant or lactating, have prior ipsilateral breast radiation, clinical/radiologic metastatic nodes, recent ferumoxytol, iron overload, hypersensitivity to iron/dextran/Magtrace, or preexisting breast discoloration that would confound assessments are unlikely to benefit from participation.

What this trial studies

This prospective US study enrolls adults undergoing breast-conserving surgery with planned sentinel lymph node biopsy using 1 ml Magtrace and maps nodes with the Sentimag system. Baseline and postoperative patient-reported outcomes will be collected using the BREAST-Q, and a Sentimag count will be recorded for each removed node. Investigators will document the presence, size, and severity of any Magtrace-related skin discoloration and follow affected participants periodically up to 24 months or until discoloration resolves. A key secondary objective is to show non-inferiority of sentinel lymph node detection rates with Magtrace compared to ASBRS performance standards.

Why it matters

Potential benefit: If successful, the results could support wider use of Magtrace as a non-radioactive option that reliably identifies sentinel nodes with a low rate of lasting skin staining.

How similar studies have gone: International studies of Magtrace have shown comparable sentinel node detection rates to conventional tracers but have also reported skin staining, and prospective US-specific data remain limited.

Show full inclusion / exclusion criteria
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.
