High Dose vs Low Dose I 131 +/- rhTSH for Differentiated Thyroid Cancer

Phase 3
Active, not recruiting
Conditions
Head and Neck Cancer
Interventions
Biological: recombinant thyroid-stimulating hormone
Radiation: Radiodine ablation without rhTSH
Registration Number
NCT00415233
Lead Sponsor
University College, London
Brief Summary

RATIONALE: Radioactive iodine uses radiation to kill tumor cells. Giving iodine I 131 with or without thyroid-stimulating hormone after surgery may kill any tumor cells that remain after surgery. It is not yet known which dose of iodine I 131 is more effective when given with or without thyroid-stimulating hormone in treating thyroid cancer.

PURPOSE: This randomized phase III trial is studying two different doses of iodine I 131 to compare how well they work when given with or without thyroid-stimulating hormone in treating patients who have undergone surgery for thyroid cancer.

Detailed Description

OBJECTIVES:

Primary

* Compare the percentage of successful remnant ablation at 6-8 months after administration of high- vs low-dose iodine I 131 with vs without recombinant thyroid-stimulating hormone in patients who have undergone total thyroidectomy for differentiated thyroid cancer.

Secondary

* Compare quality of life in patients treated with these regimens.

* Compare locoregional recurrence in patients treated with these regimens.

* Compare distant metastases, survival, and incidence of second primary malignancies in patients treated with these regimens.

OUTLINE: This is a multicenter, factorial, randomized study. Patients are stratified according to treatment center and disease stage (I vs II vs III vs IVA). Patients are randomized to 1 of 4 treatment arms.

Patients receive thyroid hormone replacement therapy (THRT)\* with thyroxine (T4)\*\* or liothyronine sodium (T3). Patients randomized to arm III or IV discontinue THRT 4 weeks (for patients receiving T4) or 2 weeks (for patients receiving T3) prior to remnant ablation.

NOTE: \*Some treatment centers may chose to avoid starting THRT in patients randomized to arm III or IV.

NOTE: \*\*Patients receiving T4 may be switched to T3 for 2 more weeks before discontinuing THRT.

* Arm I: Patients receive recombinant thyroid-stimulating hormone (rTSH) intramuscularly on days 1 and 2 and undergo remnant ablation with low-dose iodine I 131 on day 3.

* Arm II: Patients receive rTSH as in arm I and undergo remnant ablation with high-dose iodine I 131 on day 3.

* Arm III: Patients undergo remnant ablation with low-dose iodine I 131 as in arm I.

* Arm IV: Patients undergo remnant ablation with high-dose iodine I 131 as in arm II.

Quality of life is assessed at baseline, day 3 before remnant ablation, and at 3 months.

After completion of study therapy, patients are followed at 3 months, between 6-8 months, and then annually thereafter.
