Evaluating the Use of Magnetic Resonance Imaging and Contrast Enhanced Mammography After MagTrace® Use

Not yet recruiting
Conditions
Breast Cancer
Interventions
Diagnostic Test: MRI
Registration Number
NCT05637528
Lead Sponsor
Zuyderland Medisch Centrum
Brief Summary

Rationale: MagTrace® will be implemented as standard of care for sentinel lymph node biopsy, since it has several advantages compared to a radioactive technique. However, MagTrace® is known to interfere with MRI during follow-up imaging when using 2 mL. No data is available for patients who received 1 mL of MagTrace®, as is described in our current protocol. A contrast enhanced mammography (CEM) could be an alternative for MRI if it still shows artefacts.

Objective: The primary objective in this trial is to evaluate the use of MRI and contrast enhanced mammography after using MagTrace® to perform a sentinel node biopsy.

Study design: Prospective trial in an outpatient clinic setting.

Study population: Patients who were included in the previous MagTrace study will be asked to participate in this subsequent trial.

Study procedure: Participants will undergo MRI and CEM as standard 1-year follow-up. Since the MagTrace study started in August 2021 and finished in February 2022, this trial will start August 2022 to February 2023.

Main study parameters/endpoints: To evaluate the use of MRI and CEM, the following primary endpoints will be assessed: Visibility and size of artefacts undergoing MRI and CEM and its consequences of the quality for image assessment.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Since MagTrace® will be implemented as standard localisation technique for breast conserving surgery and sentinel lymph node biopsy in Zuyderland MC, the information obtained from this trial is essential for the follow-up planning of all breast cancer patients. Therefore, the burden for the patients (undergoing extra imaging) will be in proportion to the added value of this trial.

Primary Outcome Measures
NameTimeMethod
Are there any artefacts visible when undergoing an MRI?One year after surgery

Visible artefacts on MRI

Are there any artefacts visible when undergoing a CEM?One year after surgery

Visible artefacts on CEM

Secondary Outcome Measures
NameTimeMethod
Size of the possible artefact.One year after surgery

Size of the artefacts on MRI and mammography

The possibility to assess the imaging by a trained radiologistOne year after surgery

The radiologist will score the assessability using a 4 point scoring system:

0. No artefact

1. Good diagnostic quality

2. Impaired but still readable

3. Hampered clinical assessment
