About this trial
The overall aim is to demonstrate that the use of superparamagnetic iron oxide nanoparticles (SPIO) as a tracer in an ultra-low dose (0.1 ml) is non-inferior for sentinel lymph node (SLN) detection in patients with breast cancer compared to the dual technique using Tc99m +/- blue dye, and to evaluate MRI breast artefacts and skin staining over time.

Treatments tested in this trial
Superparamagnetic Iron Oxide
DrugSuperparamagnetic iron oxide (SPIO) consists of an iron oxide nanoparticle core and a hydrophilic coating to make it biocompatible and colloidal stable in a suspension. In this study injected intradermally in an ultra-low dose
Technetium99
DeviceTechnetium99 +/- blue dye is injected per routine as a comparator and as back up.
Treatment groups
Trial outcomes
Primary outcomes
SLN detection rate for Magtrace 0.1 ml and for dual technique (Tc99 +/- blue dye) measured as per cent of patients where a SLN is identified using either the magnetic or the dual technique.
percentage
Secondary outcomes
MRI Magtrace artefacts
Measured as per cent of patients with remaining artefacts evaluated by blinded central review.
Skin staining due to injected Magtrace
Measured as per cent of patients with remaining brown or blue skin staining and stain size, evaluated by the investigator and the Skin Discoloration Impact Evaluation Questionnaire (SDIEQ)
Rate of device-related AE and SAEs
Number
Numbers of nodes detected and removed for Magtrace 0.1 ml and for the dual technique (Tc99 +/- blue dye)
