Registration Number
NCT00416949
Lead Sponsor
Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins
Brief Summary

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.

Detailed Description

OBJECTIVES:

* 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.
