Primary Outcome Measures

Name	Time	Method
<p>The main study parameter will be the accuracy (sensitivity, specificity, NPV<br /><br>and PPV) of the MRL in predicting the involvement of metastases in the<br /><br>investigated lymph nodes. We will compare the results of the MRL with the<br /><br>pathological results of a negative SLNB or the ALND.<br /><br>In cases with a positive MRL and negative SLNB, we will investigate if the MRL<br /><br>is really wrong, or that we probably found a case of a false negative SNLB<br /><br>procedure. </p><br>
