Who may be able to join

  • Adults ≥ 18 years of age.
  • Patients with a core needle biopsy diagnosis consistent with ductal carcinoma in-situ (DCIS), Stage 0 breast cancer, who are planning to undergo a mastectomy.
  • o The mastectomy can be with or without reconstruction and with or without contralateral prophylactic mastectomy.

About this study

The standard surgical approach for all patients undergoing mastectomy for the treatment of non-invasive, ductal carcinoma in situ (DCIS) is to perform axillary lymph node staging through use of a traditional sentinel lymph node biopsy (SLNB) procedure where the lymph nodes that drain the breast first are removed at the time of mastectomy. This recommendation for traditional SLNB is due to the risk of finding invasive cancer during surgical evaluation of the mastectomy specimen and the inability to accurately map the lymphatic channels once the breast is removed.

In a study by Herremans et al, the majority of traditional SLNBs were demonstrated to be unnecessary. By using Magtrace, a novel iron based lymphatic mapping agent, a delayed SLNB could eliminate these unnecessary traditional SLNBs.

Magtrace, or superparamagnetic oxide (SPIO), was developed in 2018. Unlike traditional mapping agents of blue dye and technetium that clear the body within 24-48 hours, Magtrace remains in the lymph nodes for at least 4 weeks. Magtrace's ability to remain in the lymph node allows accurate mapping of the lymph nodes at the time of the mastectomy with the ability to return to the operating room for a delayed sentinel lymph node biopsy if invasive cancer is found on final pathology.

This study will investigate whether the use of Magtrace will successfully allow patients with DCIS undergoing mastectomy to avoid undergoing SLNB.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of patients with DCIS who do not undergo sentinel lymph node biopsy

    Determine the percentage of patients with DCIS who do not undergo sentinel lymph node biopsy.

    Measured: 24 months post-mastectomy

Secondary outcomes (3)
  1. Percentage of patients that are found to have invasive disease at time of mastectomy

    Determine the Percentage of patients that are found to have invasive disease at time of mastectomy.

    Measured: At the time of mastectomy

  2. Rate of return to operating room for delayed sentinel lymph node biopsy

    Determine the number of patients who return to the operating room for delayed sentinel lymph node biopsy.

    Measured: 24 months post-mastectomy

  3. Patient-reported outcomes measures

    Compare the scores obtained to the historical control for each of the following scales of the Breast-Q questionnaire: psychosocial well-being, sexual well-being, cancer worry, fatigue, and impact on work.

    Measured: 24 months post-mastectomy

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Magtrace in people with Ductal Carcinoma in Situ, run by University of Florida at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: paused, as of the sponsor's last update on 11 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients with DCIS who do not undergo sentinel lymph node biopsy (time frame: 24 months post-mastectomy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2026.
