About this study
Official title: A Prospective, Open Label Study of the Use of Magseed® and Sentimag® to Localize Axillary Lymph Nodes With Biopsy-Proven Metastases in Breast Cancer Patients
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.
Read the detailed description
PRIMARY OBJECTIVE:
- To provide evidence that the clipped lymph node and Magseed can be successfully retrieved in the excised surgical specimen when Magseed and Sentimag are used for targeted axillary dissection in breast cancer patients.
OUTLINE:
Patients receive the Magseed marker via ultrasound guided injection into the previously clipped lymph node or within perinodal tissue =< 3 mm from the clipped node. Patients then undergo axillary lymph node localization and targeted dissection within 30 days.
After completion of study, patients are followed up within 6-22 days post-surgery.
- Conditions
- Breast Carcinoma Metastatic in Lymph Node, Stage II Breast Cancer AJCC v6 and v7, Stage IIA Breast Cancer AJCC v6 and v7, Stage IIB Breast Cancer AJCC v6 and v7, Stage IIIA Breast Cancer AJCC v7, Stage IIIB Breast Cancer AJCC v7
- Being tested
- Axillary Lymph Node Dissection, Localization, Medical Device
- Medical subject headings
- Breast Neoplasms

Patients then undergo axillary lymph node localization and targeted dissection within 30 days. Receives: Procedure: Axillary Lymph Node Dissection; Procedure: Localization; Device: Medical Device |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: Up to 6 weeks post-procedure
Secondary outcomes (5)
Radiologist rated ease of Magseed placement
Descriptive statistics will be used to summarize the radiologist rated ease of Magseed placement. Logistic regression models and/or linear regression models will be used to assess the association of variables with patient's characteristics in multivariate setting. Other statistical methods, when appropriate, may be used for analysis.
Measured: Up to 15 months
Accuracy of Magseed placement
Will be defined as accurate, marginal or inadequate. Descriptive statistics will be used to summarize accuracy of placement. Logistic regression models and/or linear regression models will be used to assess the association of variables with patient's characteristics in multivariate setting. Other statistical methods, when appropriate, may be used for analysis.
Measured: Up to 15 months
Surgeon rated ease of node localization and removal
Descriptive statistics will be used to summarize surgeon rated ease of localization. Logistic regression models and/or linear regression models will be used to assess the association of the above mentioned variables with patient's characteristics in multivariate setting. Other statistical methods, when appropriate, may be used for analysis.
Measured: Up to 15 months
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. Logistic regression models and/or linear regression models will be used to assess the association of the above mentioned variables with patient's characteristics in multivariate setting. Other statistical methods, when appropriate, may be used for analysis.
Measured: Up to 15 months
Transcutaneous detection rate
Descriptive statistics will be used to summarize transcutaneous detection rate. Logistic regression models and/or linear regression models will be used to assess the association of the above mentioned variables with patient's characteristics in multivariate setting. Other statistical methods, when appropriate, may be used for analysis.
Measured: Up to 15 months
