Brief Summary
The aim of this study is to compare the efficacy of the Sentimag localization system and its tracer Magtrace, superparamagnetic iron oxide nanoparticles, as a tracer in sentinel node biopsy in breast cancer with Tc99 in a single-center prospective study. The other part of the study will be the implantation of the smallest non-radioactive seed, Magseed, in the non-palpable breast cancer lesions. Another part of the study will be the implantation of Magseed in the positive axillary lymph nodes in patients diagnosed with clinically positive lymph nodes that will receive neoadjuvant systemic therapy.

Outcome Measures
Primary Outcomes (6)
Accuracy of Magseed placement
Accuracy of Magseed placement will be measured regarding its position towards the lymph node in mm. Will be defined as accurate, marginal or inadequate. Descriptive statistics will be used to summarize accuracy of placement. Other statistical methods, when appropriate, may be used for analysis.
During the surgical procedure
Surgeon-rated ease of detected lymph node localization and removal
Descriptive statistics will be used to summarize surgeon rated ease of localization.
During the surgical procedure
Number of nodes retrieved within the surgical specimen containing the Magseed
Descriptive statistics will be used to summarize number of nodes retrieved within the surgical specimen containing the Magseed.
During the surgical procedure
Surgeon-rated ease of detected labeled lesion localization and removal
Descriptive statistics will be used to summarize number of nodes retrieved within the surgical specimen containing the Magseed.
During the surgical procedure
Transcutaneous detection rate
Descriptive statistics will be used to summarize transcutaneous detection rate.
During the surgical procedure
Incidence of adverse events
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
Study Arms (3)
Non-palpable breast cancer lesion
Patients with the non-palpable histologically confirmed breast cancer lesion that will undergo breast-conserving surgery and sentinel lymph node detection - the tumor lesion will be labeled with Magseed.
Palpable breast cancer lesion
Patients with the palpable histologically confirmed breast cancer lesion that will undergo breast-conserving surgery and sentinel lymph node detection - The Magtrace will be injected preoperatively into the tumor and detected by Sentimag.
Axillary lymph node metastasis
Patients with the histologically confirmed breast cancer lesion with Axillary lymph node metastasis with pathologic confirmation by needle biopsy - the positive axillary lymph node lesion will be labeled with Magseed before the neoadjuvant systemic therapy.
Interventions
Patients with the non-palpable histologically confirmed breast cancer lesion - the tumor lesion will be labeled with Magseed and patient will undergo breast-conserving surgery and sentinel lymph node detection with Tc99.
Patients with the palpable histologically confirmed breast cancer lesion - The Magtrace will be injected preoperatively into the tumor and detected by Sentimag. Patient will undergo sentinel lymph node detection with Tc99 and Sentimag localization system with breast surgery.
Patients with the histologically confirmed breast cancer lesion with Axillary lymph node metastasis with pathologic confirmation by needle biopsy - the positive axillary lymph node lesion will be labeled with Magseed before the neoadjuvant systemic therapy, and later during target axillary dissection will be performed the biopsy of labeled lymph node during breast surgery.
Eligibility Criteria
