- Primary Outcome Measures
Name Time Method <p>The primary objective of this study is to assess feasibility of intraoperative<br /><br>visualization of small intestine neuroendocrine tumors (SI-NET). Feasibility is<br /><br>defined as a Tumor-to-Background Ratio (TBR) of >= 1.5 in at least 60% of the<br /><br>patients. TBR will be assessed based on in vivo measurements on the primary<br /><br>SI-NET. </p><br>
- Secondary Outcome Measures
Name Time Method <p>- To asses the ex vivo TBR of the primary SI-NET<br /><br>- To assess the TBR of (lymph node) metastases;<br /><br>- To assess the number of extra (occult) lesions found and their fluorescence<br /><br>intensity;<br /><br>- To assess fluorescence signal on the pathology slides;<br /><br>- To assess the optimal dose of ICG to visualize the primary tumor.</p><br>
