Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The proportion of sentinel nodes correctly detected with the magnetic method 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 „³ sensitivity; 4. The number and percentage of sentinel lymph nodes correctly diagnosed to be non-metastatic using ex vivo MRI specificity. | — |
Secondary
| Measure | Time frame |
|---|---|
| 5. The iron content in the dissected sentinel lymph nodes (average, minimum and maximum) in relation to the image quality; 6. The image parameters indicative for the presence of sentinel lymph node metastases; 7. The requirements in detection depth and minimally detectable mg iron per node for future magnetometers; 8. The usability of a dose of 1.1 mg iron in 1 ml injected volume for the proposed study. | — |
