Tracer administration: Bevacizumab-800CW is administered via an IV 2 days
before surgery and patients are monitored for any
to be able to observe side effects. Dosages of 4.5 / 10 / 25mg can be used

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary endpoint - Fluorescent signal levels defined as Tumor-to-Background Ratio (TBR) derived from PTC/FTC/HTC/PDTC nodal metastasis and normal tissue to determine the optimal dose of Bevacizumab-800CW in patients with PTC/FTC/HTC. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints - Correlation of the fluorescent signal in PTC/FTC/HTC, nodal metastasis and normal tissue assessed by MFGS with other biological and molecular parameters (IHC) and the fluorescent signal assessed in the ex vivo biopsy specimens. - Wound bed biopsy specimen characteristics (number of positive and negative biopsies. - Distribution of bevacizumab-IRDye800CW in PTC/FTC/HTC, lymph nodes and normal tissue as identified by SDS-PAGE and/or ELISA and/or fluorescence microscopy. - Quantification of sensitivity and specificity of Bevacizumab-800CW in order to make a power size calculation for a possible subsequent diagnostic accuracy study. | — |
