Preferred Label : Stage IVA Oropharyngeal (p16-Negative) Carcinoma AJCC v8;
NCIt related terms : Stage IVA Oropharyngeal (p16-Negative) Throat Cancer;
NCIt definition : Stage IVA includes: (T4a, N0, M0); (T4a, N1, M0); (T1, N2, M0); (T2, N2, M0); (T3,
N2, M0); (T4a, N2, M0). T4a: Moderately advanced local disease. Tumor invades the
larynx, 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 the larynx. T1: Tumor 2 cm or
smaller in greatest dimension. T2: Tumor larger than 2 cm but not larger than 4 cm
in greatest dimension. T3: Tumor larger than 4 cm in greatest dimension or extension
to lingual surface of epiglottis. N0: No regional lymph node metastasis. N1: Tumor
with metastasis in a single ipsilateral lymph node, 3 cm or smaller in greatest dimension
and ENE(-). N2: Tumor with metastasis in a single ipsilateral lymph node, 3 cm or
smaller in greatest dimension and ENE( ); or larger than 3 cm but not larger than
6 cm in greatest dimension and ENE(-); or metastases in multiple ipsilateral lymph
nodes, none larger than 6 cm in greatest dimension and ENE(-); or metastases in bilateral
or contralateral lymph nodes, none larger than 6 cm in greatest dimension and ENE(-).
M0: No distant metastasis. (AJCC 8th ed.);
