Prospective Study Evaluating the Medullary Thyroid Cancer Management's Care Using PET ( Positron Emission Tomography) F-DOPA in Patients With a High Level of Postoperative Residual Thyrocalcitonin

Intervention Type: Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY

The aim of the trial is to study a radiating diagnosis agent used in post surgery when the biological assessment highlighted a residual disease. This is an inter-regional multicentric, prospective study evaluating the benefit of PET F-DOPA imaging in involved node detection compared to standard imaging assessment in patient with medullary thyroid cancer. The purpose of the study is to evaluate the impact and performance of a new PET / CT (computerized tomography ) tracer targeting dopamine receptor in patient with residual ganglionar biological disease after initial surgery of medullary thyroid cancer compared to standard imaging. Obtained data will be compared to the gold standard based on : nodes cytology when they could be punctured histology when a new surgery will be recommended surveillance when the 2 first cases will be not applicable (imaging monitoring, evolution of thyrocalcitonin)

Participants
Target number of participants: 24
Treatments
Other: PET 18-FDOPA
18F-DOPA will be administered with an activity of 1.5-4 MBq/kg (MegaBecquerel) in the IV (Intra venous) tubing to decrease the extravasation risk and tracer lymphatic migration. The injection site will be distant from pathologic area (forearm).~PET CT exam will start 10 min after tracer injection and will cover the whole body (10 to 30 min).~Other series of images will be done 50 min after tracer injection. Images will be interpreted.
