NCIt definition : Stage IV includes: IVA (T4a, N0, M0); (T4a, N1, M0); (T1, N2, M0); (T2, N2, M0); (T3,
N2, M0); (T4a, N2, M0); IVB (T4b, Any N, M0); (Any T, N3, M0); IVC (Any T, Any N,

extrinsic muscle of tongue, medial pterygoid, hard palate, or mandible. Mucosal extension
to lingual surface of epiglottis from primary tumors of the base of the tongue and
vallecula does not constitute invasion of larynx. T1: Tumor 2 cm or less in greatest
dimension. T2: Tumor more than 2 cm but not more than 4 cm in greatest dimension.
T3: Tumor measuring more than 4 centimeters in greatest dimension or extension to
lingual surface of epiglottis. T4b: Tumor with very advanced local disease. Tumor
invades lateral pterygoid muscle, pterygoid plates, lateral nasopharynx, or skull
base or encases carotid artery. N0: No regional lymph node metastasis. N1: Metastasis
in a single ipsilateral lymph node, 3 cm or less in greatest dimension. N2: Tumor
with metastasis in a single ipsilateral lymph node, more than 3 cm but not more than
6 cm in greatest dimension, or in multiple ipsilateral lymph nodes, none more than
6 cm in greatest dimension, or in bilateral or contralateral lymph nodes, none more
