Papillary Thyroid Cancer

This is an excerpt from the content

Pearls and Pitfalls

  • Papillary thyroid cancer (PTC) accounts for 80% of all thyroid cancers and is the most rapidly increasing cancer in women in the United States.

  • Latent thyroid cancer is present in 6.2–36% of thyroid glands at autopsy.

  • Neck ultrasound evaluates the thyroid gland for suspicious nodules, as well as for thyroid cancer metastasis in cervical lymph nodes.

  • Fine needle aspiration biopsy cytology (FNAC) under ultrasound guidance accurately diagnoses papillary, medullary, and anaplastic thyroid cancer and/or lymph node involvement.

  • A total or near-total thyroidectomy is indicated for most patients with clinical thyroid cancer greater than 1 cm in size.

  • Central neck and/or lateral neck dissection is indicated for clinically or scan-positive abnormal lymph nodes.

  • A nonoperative approach is being done in Japan for patients with isolated micro PTC (≤1 cm) by FNAC without nodal involvement, in whom the tumor is not adjacent to the recurrent laryngeal nerve or trachea.
