| Main Objective: Uspio enhanced MRI (MRL) has the ability to show all lymph nodes and hence provide information on metastasis in all nodes, in contrast with SLNB which only provides information on 1 lymph node. With MRL metastases down to a size of 1 mm are detected. In 38% to 62% of patients with a positive sentinel lymph node (SLN), the SLN is the only positive node. ALND is performed in all these women and only afterwards judged unnecessary. We expect MRL to be able to identify women who have no (further) involvement of lymph nodes prior to SLNB or after a positive SLNB. Consequently ALND can be withheld from these women. MRL may also prove valuable in the 4% of patients where localisation of the SLN fails. Finally, because SLNB is false negative in 7-9% of patients, some patients are inadequately treated. MRL has a high sensitivity and provides information on all lymph nodes, consequently it may reduce the number of false negative SLNB findings. ;Secondary Objective: · Sensitivity on a node to node basis · Specificity, Accuracy, negative predictive value and positive predictive value on a patient to patient and node to node basis · Posttest probability negative rate · Feasibility of MRL after SLNB · Diagnostic accuracy of MRL after SLNB · Prognostic value of IMN involvement · Prognostic value of positive and negative MRL after positive SLNB followed by irradiation of the axilla · Feasibility of MRL after neoadjuvant chemotherapy · Diagnostic accuracy of MRL after neoadjuvant chemotherapy · Effect of chemotherapy on tumor positive axillary lymph nodes;Primary end point(s): The primary endpoint is the sensitivity of MRL for proved lymph node involvement by histopathology on a patient to patient basis | — |
