Brief Summary
This phase IV trial studies the side effects of the Magseed magnetic marker and how well it works in locating lymph nodes in the underarm area in patients with breast cancer undergoing surgery. Injecting a small metallic marker in or near the lymph node prior to surgery may help the surgeon locate the lymph nodes during surgery without using radiation.

Outcome Measures
Primary Outcomes (2)
Retrieval rate
Will be defined as the number of subjects in whom the clipped node and Magseed are retrieved in a single excised specimen divided by the total number of subjects. For the analysis of retrieval rate, if the trial is not stopped early and all 50 patients are accrued, then point estimate along with 95% credible interval will be provided. Logistic regression model will be utilized to assess the association of patient demographic and clinical factors with the retrieval.
Up to 15 months
Incidence of adverse events
Will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0. Toxicity data will be summarized by frequency tables. For the toxicity endpoint, per-treated analysis will be used to include any patient who received the treatment regardless of the eligibility nor the duration or dose of the treatment received.
Up to 6 weeks post-procedure
Secondary Outcomes (5)
Radiologist rated ease of Magseed placement
Up to 15 months
Accuracy of Magseed placement
Up to 15 months
Surgeon rated ease of node localization and removal
Up to 15 months
Number of nodes retrieved within the surgical specimen containing the Magseed
Up to 15 months
Transcutaneous detection rate
Up to 15 months
Study Arms (1)
Diagnostic (Magseed marker)
EXPERIMENTALPatients receive the Magseed marker via ultrasound guided injection into the previously clipped lymph node or within perinodal tissue =\< 3mm from the clipped node. Patients then undergo axillary lymph node localization and targeted dissection within 30 days.
Interventions
Undergo targeted axillary lymph node dissection
Receive Magseed via ultrasound guided injection
Eligibility Criteria
You may qualify if:
- Histologically confirmed cT0-4, N1 breast cancer
- Axillary lymph node metastasis with pathologic confirmation by needle biopsy
- Clip placed in the sampled axillary lymph node before completing chemotherapy
- Received neoadjuvant chemotherapy prior to surgical resection
- Scheduled for targeted axillary dissection (defined as selective localization and removal of the clipped node and sentinel lymph node dissection \[SLND\])
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
You may not qualify if:
- Distant metastases
- Inflammatory breast cancer
- Prior surgical axillary procedure including SLND or axillary node excision
- Prior history of breast cancer in the ipsilateral breast
- History of lymphoma
- The subject is known to be pregnant. Premenopausal patients under the age of 50 must have a pregnancy test performed as standard of care before the MagSeed is placed
- Previous radiation to the breast or axilla
- Pacemaker of other implantable device in the chest wall
