The ATA does not have comprehensive guidelines for the treatment of follicular thyroid cancer (FTC) and Hürthle cell carcinoma as separate entities from papillary thyroid cancer; however, there are several individual recommendations that apply decision-making principles to these conditions. [37]

The ATA recommends that if cytology readings report a follicular neoplasm, an 123I thyroid scan may be considered, especially if serum thyroid-stimulating hormone (TSH) is in a low-normal range. If a concordant autonomously functioning nodule is not seen, lobectomy or total thyroidectomy should be considered.

If the cytology report indicates “Hürthle cell neoplasm” or “suspicious for papillary carcinoma”, the ATA recommends a lobectomy or thyroidectomy, depending on nodule size and other risk factors.

For patients with an isolated indeterminate (“follicular neoplasm” or “Hürthle cell neoplasm”) solitary nodule who prefer a more limited approach, the ATA recommends an initial lobectomy.

The ATA recommends a total thyroidectomy for patients with indeterminate nodules in any of the following situations:

  • The tumor exceeds 4 cm
  • Marked atypia is observed
  • Biopsy result is reported as “suspicious for papillary carcinoma”
  • The patient has a family history of thyroid carcinoma
  • The patient has a history of radiation exposure

The ATA recommends that patients with indeterminate nodules who have bilateral nodular disease or who wish to avoid future surgery should undergo total or near-total thyroidectomy. [37]
