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

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.

Cohorts and Interventions

Group / Cohort
differentiated thyroid cancer
Patients with locally recurrent thyroid cancer, treated with radical radiotherapy after total thyroidectomy +/- central compartment and/or laterocervical lymphadenectomy, previously treated with one or more cycles of 131 Iodine-ablation (RAI) and TSH suppression.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
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).
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
toxicities
Time Frame: 6 months
Acute and late toxicities after radiotherapy are assessed with CTCAE v. 4.03 and EORTC-RTOG scales, respectively.
6 months
