18F-FDG PET-guided External Beam Radiotherapy in Iodine-refractory Differentiated Thyroid Cancer
Description of the role of a post-operative external beam radiotherapy in patients with differentiated thyroid cancer.
Study Overview
Status
Completed
Conditions
Detailed Description
The role of post-operative external beam radiotherapy (EBRT) in differentiated thyroid cancer is still discussed considering the low clinical aggressiveness and the availability of ablative 131Iodine therapy.
However, there is a subgroup of tumors which lose the ability to capture Iodine over time.
This study wants to describe the role of a post-operative external beam radiotherapy in patients with differentiated thyroid cancer.

Measure Description |
Time Frame |
---|---|---|
Progression free survival (PFS)
Time Frame: 6 months
|
Progression-free survival (PFS) after radiotherapy is evaluated with CT-scan and 18F FDG PET-scan.
Also laboratory tests are performed (HTG serum level evaluation in case of biochemical recurrence).
