Eligibility
Inclusion criteria
Inclusion criteria: Adult, clinically (palpation and ultrasound) node negative, patients that are diagnosed with invasive breast cancer or high grade ductal carcinoma in situ and that are scheduled for a two-day SLNB procedure and that gave informed consent for participation to the study;
Exclusion criteria
Exclusion criteria: 1.Patients incapable of giving informed consent for participation to the study; 2.Intolerance / hypersensitivity to iron or dextran compounds; 3.Patients that have received neoadjuvant chemotherapy in the period of 5 years prior to this study. 4.Pregnant or lactating patients
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The proportion of sentinel nodes correctly detected with the magnetic technique (magnetometer) as compared to the combined technique (visually and/or using the gammaprobe). 2. The proportion of patients in which the sentinel lymph nodes could successfully be detected (detection rate) using the magnetometer. 3. The number and percentage of sentinel lymph nodes correctly diagnosed to be metastatic using ex vivo MRI. 4. The number and percentage of sentinel lymph nodes correctly diagnosed to be non-metastatic using ex vivo MRI. | — |
Secondary
| Measure | Time frame |
|---|---|
| 5. The iron content in the dissected lymph nodes (average, minimum and maximum) in relation to the image quality; 6. The image parameters indicative for the presence of lymph node metastases; 7. The requirements in detection depth and minimally detectable mg iron per node for future magnetometers. | — |
