Current Clinical Trials

The most common sites of metastases are lymph nodes, lung, and bone. Treatment of lymph node metastases alone is often curative. Treatment of distant metastases is usually not curative but may produce significant palliation.

Standard treatment options:

1. I¹³¹: Metastases that demonstrate uptake of this isotope may be ablated by therapeutic doses of I¹³¹.



2. External-beam radiation therapy for patients with localized lesions that are unresponsive to I¹³¹.[1]



3. Resection of limited metastases, especially symptomatic metastases, should be considered when the tumor has no uptake of I¹³¹.



4. Thyroid-stimulating hormone suppression with thyroxine is also effective in many lesions not sensitive to I¹³¹.

Patients unresponsive to I¹³¹ should also be considered candidates for clinical trials testing new approaches to this disease.

Treatment options under clinical evaluation:

• Clinical trials evaluating new treatment approaches to this disease should also be considered for these patients. Chemotherapy has been reported to produce occasional complete responses of long duration.[2-4]

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with stage IV papillary thyroid cancer and stage IV follicular thyroid cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
