Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective of this study is to prove the concept of sentinel lymph node imaging in thyroid carcinoma using preoperative 68Ga-tilmanocept PET/CT combined with intraoperative gamma probe and fluorescence camera localization. The number of visualized and resected SLNs will be assessed.;Secondary Objective: To<br>•Assess the localization of the sentinel lymph nodes<br>•Compare the pathological results of the sentinel lymp nodeswith the results of the rest of the lymph node level<br>•Define the optimal scan protocol<br>•Assess the (additional) surgical time<br>•Quantify how the surgeon experiences the complexity, feasibility and additional value of the various methods to identify the sentinel lymph nodesusing a questionnaire<br>;Primary end point(s): •Number of sentinel lymph nodes determined on PET/CT<br>•Number of resected sentinel lymph nodes <br>;Timepoint(s) of evaluation of this end point: Within 2 days
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): •Localization of sentinel lymph nodes<br>•Pathology result of sentinel lymph nodes compared to pathology result of rest of lymph node level<br>•Optimal scan protocol<br>•(Additional) surgical time<br>•Questionnaire directed to the surgeon about complexity, feasibility and additional value of various identification methods for sentinel lymph nodes<br>;Timepoint(s) of evaluation of this end point: Approximately 1-10 days
