Design outcomes

Primary

Measure	Time frame
The primary outcome parameters are identification rate of SLN(s) or lymph node metastases with bevacizumab-800CW, defined as the number of patients in which a SLN or lymph node metastasis was detected due to fluorescence during surgery and/or pathology assessment divided by the total number of procedures. Furthermore the rate of adverse events related towards bevacizumab-800CW will be measured. This is defined as the number of adverse events related towards bevacizumab-800CW/total number of procedures.	—

Secondary

Measure	Time frame
Secondary outcome parameters include: amount of fluorescence in lymph node metastases compared to lymph node without metastases, false-negative SLNs, true-negative SLNs, sensitivity, upstaged patients, aberrant lymph node status, accuracy, negative predictive value and number of SLNs identified.	—
