**Thyroid TNM staging**
Stage	Description
TX	Primary tumor cannot be assessed.
T0	No evidence of primary tumor.
T1	Tumor ≤2 cm in greatest dimension limited to the thyroid.
T1a	Tumor ≤1 cm, limited to the thyroid.
T1b	Tumor >1 cm but ≤2 cm in greatest dimension, limited to the thyroid.
T2	Tumor >2 cm but ≤4 cm in greatest dimension, limited to the thyroid.
T3	Tumor >4 cm in greatest dimension limited to the thyroid or any tumor with minimal extrathyroid extension (e.g., extension to sternothyroid muscle or perithyroid soft tissues).
T4a	Moderately advanced disease.
T4a	Tumor of any size extending beyond the thyroid capsule to invade subcutaneous soft tissues, larynx, trachea, esophagus, or recurrent laryngeal nerve.
T4b	Very advanced disease.
T4b	Tumor invades prevertebral fascia or encases carotid artery or mediastinal vessel.
T4a	Intrathyroidal anaplastic carcinoma.
T4b	Anaplastic carcinoma with gross extrathyroid extension.

**Regional Lymph Nodes (N)**
Stage	Description
NX	Regional lymph nodes cannot be assessed.
N0	No regional lymph node metastasis.
N1	Regional lymph node metastasis.
N1a	Metastases to Level VI (pretracheal, paratracheal, and prelaryngeal/Delphian lymph nodes).
N1b	Metastases to unilateral, bilateral, or contralateral cervical (Levels I, II, III, IV, or V) or retropharyngeal or superior mediastinal lymph nodes (Level VII).

**Distant Metastasis (M)**
Stage	Description
M0	No distant metastasis.
M1	Distant metastasis.

**Anatomic Stage/Prognostic Groups**
Stage	T	N	M
Papillary or follicular (differentiated)
YOUNGER THAN 45 YEARS
I	Any T	Any N	M0
II	Any T	Any N	M1
45 YEARS AND OLDER
I	T1	Any N	M1
II	T2	N0	M0
III	T3	N0	M0
	T1	N1a	M0
	T2	N1a	M0
	T3	N1a	M0
IVA	T4a	N0	M0
	T4a	N1a	M0
	T1	N1b	M0
	T2	N1b	M0
	T3	N1b	M0
	T4a	N1b	M0
IVB	T4b	Any N	M0
Stage IVC	Any T	Any N	M1
