Thyroid Cancer Treatment (Professional) (cont.)

Stage III Papillary and Follicular Thyroid Cancer

Standard treatment options:

  1. Total thyroidectomy plus removal of involved lymph nodes or other sites of extrathyroid disease.
  2. I131 ablation following total thyroidectomy if the tumor demonstrates uptake of this isotope.[1]
  3. External-beam radiation therapy if I131 uptake is minimal.[2]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage III papillary thyroid cancer and stage III 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.

Stage IV Papillary and Follicular Thyroid Cancer

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.[2,3,4] Oral inhibitors of vascular endothelial growth-factor receptors are under clinical evaluation.[5][Level of evidence: 2Dii]
