Iodine I 131 in Treating Patients With Thyroid Cancer
RATIONALE: Radioactive iodine kills thyroid cancer cells by giving off radiation.
PURPOSE: This clinical trial is studying the side effects, best dose, and how well iodine I 131 works in treating patients with thyroid cancer.

- Determine the relationship between estimated absorbed dose of iodine I 131 and tumor response or normal organ toxicity for different dosimetric measures, using data derived from clinical radionuclide therapy studies in patients with thyroid cancer.
OUTLINE: Patients receive oral dosimetric iodine I 131 (^131I) on day 2 and then undergo nuclear medicine imaging at 0.5-4 hours, 24, 48, and 72 hours after dosimetric ^131I. Single-photon emission computed tomography (SPECT)/CT scans are performed at 0.5-4 hours and 24 or 48 hours over the head and neck region, including the salivary glands. Subsequent SPECT/CT scans are performed over the candidate tumor sites. Patients undergo ^131I therapy on day 11.
Saliva is collected on days 1 and 2, weeks 2 and 4, and months 3 and 6 to measure saliva flow rate. Blood is collected at baseline and periodically during study to measure FLT3 ligand levels.
PROJECTED ACCRUAL: A total of 96 patients will be accrued for this study.
