Thyroid cancer staging is done with the TNM staging system.

TNM staging system

Tumour stage not including anaplastic carcinoma

T stage Size/criteria Other requirements Comment
pT1a 1 cm or less limited to thyroid very common
pT1b >1 cm and <=2 cm limited to thyroid
pT2 >2 cm and <=4 cm limited to thyroid
pT3a >4 cm limited to thyroid changed from AJCC 7th Ed.
pT3b extension into strap muscles strap muscles include: sternothyroid m., sternothyroid, thyrohyoid, omohyoid changed from AJCC 7th Ed.
pT4a any size any of the following: subcutaneous tissue, trachea, esophagus, larynx, recurrent laryngeal nerve
pT4b any size any of the following: mediastinal vessels, encasing carotid artery, prevertebral fascia

Lymph nodes

N stage Criteria Comment
pN0 negative for lymph node metastasis
pN1a metastasis to level VI or VII level VI = pretracheal, paratracheal, prelaryngeal/Delphian, perithyroidal; VII = mediastinal lymph nodes
pN1b metastasis to level I, II, III, IV, V, or retropharyngeal (level VII changed to pN1a in AJCC 8th Ed.)
