Screening programs and advances in imaging have led to more breast lesions being diagnosed at an impalpable stage. Multiple localisation techniques for nonpalpable breast lesions have been developed during the past decades. Specifically, several alternatives to the golden standard hooked-wire technique have become available, of which magnetic seed localisation is one of the newest approaches. Since September 2018, Magseed® localisation is the standard of care for localising impalpable breast lesions in UZ Leuven. In this study, the oncological safety, the clinical safety and surgeon satisfaction of Magseed® localisation will be assessed and retrospectively compared to hooked-wire localisation.
Study Type
OBSERVATIONAL
Enrollment
192
Impalpable breast lesions are preoperatively localised, either with hooked-wire (retrospective study) or Magseed (prospective study)
University Hospitals Leuven
Leuven, Belgium
Number of participant with device-related adverse events
Time frame: Up to three weeks after surgical treatment
Total breast volume resected during breast conserving surgery
Time frame: Up to three weeks after surgical treatment
Number of participants with positive surgical margins as assessed by pathological examination of the specimen
Time frame: Up to three weeks after surgical treatment
Re-operation rate due to positive surgical margins
Time frame: Up to three weeks after surgical treatment
Surgeon satisfaction based on a questionnaire
After surgery, the surgeon will be asked to describe the magnetic seed procedure, choosing between 'easier than hooked-wire' or 'more challenging than hooked-wire'. Moreover, the surgeon wil have the chance to add additional remarks or experiences with this new technique.
Time frame: After surgery
