Gefitinib in Treating Patients With Locally Advanced or Metastatic Thyroid Cancer That Did Not Respond to Iodine Therapy
Recruitment status was Active, not recruiting
RATIONALE: Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
PURPOSE: Phase II trial to study the effectiveness of gefitinib in treating patients who have locally advanced or metastatic thyroid cancer that did not respond to iodine therapy.

- Determine the all-measurable-disease response rate in patients with iodine-refractory locally advanced or metastatic thyroid cancer treated with gefitinib.
- Determine the toxicity of this drug in these patients.
- Determine progression-free and overall survival of patients treated with this drug.
OUTLINE: This is an open-label study.
Patients receive oral gefitinib once daily. Treatment continues in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 27 patients will be accrued for this study.
